Based on this information, what type of transport is used for glucose in blood and intestinal cells?
Answer:
Facilitative glucose transporters (GLUTs)
These are responsible for the bidirectional transport of glucose in tissues and cells. This involvesusing facilitative diffusion to carry glucose down a concentration gradient, into the cell.
DNA is often compared to a twisted ladder. In this analogy, what forms the
rungs of the DNA ladder?
A. Pairs of nitrogenous bases
B. Pairs of nucleotides
C. Pairs of sugars
D. Pairs of phosphate groups
The pairs of nucleotides result in the twisting of strands. Therefore, option "B" is correct.
What is nucleotide base pairing?There are five types of nucleotide bases adenine, cytosine, guanine, thymidine, and uracil. These divide into two classes of nucleotides pyrimidine and purine nucleotide bases. Pyrimidines are uracil, thymine, and cytosine whereas adenine and guanine are purine.
In RNA, adenine, cytosine, and guanine are present but thymine is replaced by uracil. Pyrimidine always binds with the purines through hydrogen bonding. Adenine binds with thymine. Cytosine binds with guanine. But when adenine pairs with uracil in RNA.
Therefore, nucleotide base pairing determines the twisting of the DNA strand depending on the type of nucleotide present.

Cierto.
Explicación:
Todas las células no tenían pared celular. Sabemos que la célula animal es un tipo de célula que solo tiene membrana celular. Las células procariotas se originaron hace aproximadamente 3,5 mil millones de años. Los centríolos son orgánulos cilíndricos, formados por proteínas, que contribuyen en la división celular. El ADN determina las características de un organismo porque el ADN tiene toda la información sobre los organismos. La digestión celular no ocurrió en las mitocondrias. El lugar de la digestión celular son los lisosomas. En la definición de celda, la palabra estructural, se refiere a la composición y forma de la celda. La palabra eucariota significa "núcleo verdadero" y núcleo verdadero significa que la membrana rodea al núcleo.
Think of an organism you've heard of or read about that has a surprisingly unusual trait or behavior. How is this trait or behavior different from similar organisms? How does it help the organism survive in its environment?
Answer: The organism with an unusual behaviour that I have read of is the CHAMELEON
Explanation:
Behaviour is everything an organism does in response to changes in its environment. It is basically adaptive, geared mainly to promoting the organism's survival and reproduction. Generally, we associate behavioural adaptations with animals since most behaviour patterns involve movements of various body parts and locomotion. Animals exhibit a variety of behaviour patterns with respect to
--> obtaining food,
--> escape and defence,
-->surviving unfavorable conditions,
--> communication,
--> finding mates and
--> caring for the young.
The CHAMELEON is famous for its rapid colour changes as it moves from a background of one colour to another. It is DIFFERENT from other similar organisms because it can display a variety of coloured patterns to blend with its background.
The colour change exhibited by the chameleons helps the organism to obtain food and survive in its environment. The CHAMELEON simply sits still, unnoticed and when an unsuspecting insect flies by, it flicks out its tongue to catch it.
Answer:
I have heard that black bears are almost entirely vegetarian while many other bears including polar bears are carnivorous. The black is not actually considered friendly but studies have shown that compared to other animals it is quite nice. Studies have shown that the black bear is omnivorous but that it rarely and I mean rarely eats meat. This trait is different from similar species such as polar bears that eat mainly bearded seals. But maybe if they lived in a place that actually grew plants or other vegetarian things maybe it could have also been a vegetarian or even omnivores. The black bear is also considered “nice” researchers have said that when they studied black bears that they aren’t the meanest animals around which I guess is a plus. The black bears mainly live in forests or even sometimes alpines. So being omnivorous or mostly vegetarian may help the organism survive in its environment because there are a lot of plants and other greens that it can eat around the area it stays in. As well as, when it is in the alpines there may be little to no greens so it will resort to meat or fish because it has to feed its cubs or because it is simply just hungry.

1. Describe some surface mining methods.
2. What are some ways an area can undergo reclamation after being mined?
3. What makes a gemstone valuable?
4. How is an atom different from an ion? How is an atom different from an element?
5. How is a molecule different from an element? Can a molecule be an element?
6. In which type of bonding are electrons shared? In which are they given or taken? Which type of bond is stronger?
7. What is a crystal?
8. What are the eight major mineral groups?
9. How does the native elements mineral group differ from all of the other mineral groups?
10. Which properties of a mineral describe the way it breaks apart?
11. Apatite scratches the surface of an unknown mineral. Which mineral would you use next to test the mineral’s hardness—fluorite or feldspar? Explain your reasoning.
12. What is the difference between magma and lava?
13. Explain how mineral veins form.
Answer: 1:There are five recognized types of surface mining, each with specific variations depending on the minerals being extracted. These include strip mining, open-pit mining, mountaintop removal, dredging and highwall mining.
2:Refilled/reshaped w/vegetation planted; filled w/water to become a lake; turned into landfill; left open as home for bats or sealed off if underground.
3:Physical characteristics that make a colored stone valuable are color, clarity to a lesser extent (emeralds will always have a number of inclusions), cut, unusual optical phenomena within the stone such as color zoning (the uneven distribution of coloring within a gem) and asteria (star effects).
4:Atoms where the electrons and protons are not equal are called ions. Ions are charged particles. They can be either positively charged ions or negatively charged ions.
5:Molecule is a substance with two or more atoms bonded together such as the oxygen humans breathe (O2). Elements are pure substances made up of all the same atoms such as gold (Au), hydrogen (H), and oxygen (O). Elements all have the same number of protons in their nuclei and can't be broken down.
6:A covalent bond involves electrons being shared between atoms. The most stable state for an atom occurs when its valence electron shell is full, so atoms form covalent bonds, sharing their valence electrons, so that they achieve a more stable state by filling their valence electron shell.
7:A crystal or crystalline solid is a solid material whose constituents are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.
8:How does the native elements mineral group differ from all of the other mineral groups? Native elements contain atoms of only one type of element. Only a small number of minerals are found in this category. Some of the minerals in this group are rare and valuable.
9:How does the native elements mineral group differ from all of the other mineral groups? Native elements contain atoms of only one type of element. Only a small number of minerals are found in this category. Some of the minerals in this group are rare and valuable.
10:Cleavage. The way in which a mineral breaks along smooth flat planes is called cleavage. These breaks occur along planes of weakness in the mineral's structure. However, if a mineral breaks along an irregular surface, it does not have cleavage.
11: I would use fluorite to test the hardness because apatite has a higher hardness then fluorite does mean that the unknow mineral is lower on the hardness test then both apatite and feldspar. 5. Why is streak more reliable than color when identifying a mineral?
12:magma for molten rock that is underground and lava for molten rock that breaks through the Earth's surface.
13:In geology, a vein is a distinct sheetlike body of crystallized minerals within a rock. Veins form when mineral constituents carried by an aqueous solution within the rock mass are deposited through precipitation. The hydraulic flow involved is usually due to hydrothermal circulation.

You have joined a lab studying DNA replication in E. coli. The graduate student you are working with has identified a mutation in primase that makes primase very inefficient. Your project is to characterize the cells with this mutation. Predict the defects you would most likely see in the mutant E. coli cells. Choose one or more: A. a delay in the unwinding of DNA B. rapid lagging-strand synthesis but slow leading-strand synthesis C. a delay in DNA polymerase beginning synthesis D. a longer total time to replicate DNA E. inefficient Okazaki fragment joining
Answer:
C. a delay in DNA polymerase beginning synthesis
D. a longer total time to replicate DNA
Explanation:
DNA primases are RNA polymerases that play an active role during DNA replication by catalyzing the synthesis of short RNA sequences or 'primers' that are complementary to a single-stranded piece of DNA (i.e., to the DNA template). Primases are continuously required at the DNA replication fork before DNA replication can occur. Moreover, DNA polymerases always require a pre-existing primer sequence to initiate DNA chain elongation, thereby it is expected that an inefficient primase delay the DNA replication process and DNA polymerase activity.
what is the meaning of respiration
Answer:
in physiology respiration is the movement of oxygen from the outside environment to the cells with tissues and the removal of carbon dioxide in the opposite direction .. in contrast exhalation is usually a passive process
hope it's helpful
Answer:
The process of breathing.
Explanation:
The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.
**Physiological respiration and cellular respiration are not the same. People sometimes use the word "respiration" to refer to the process of cellular respiration, which is a cellular process in which carbohydrates are converted into energy. The two are related processes, but they are not the same.

Read the question and type out the
mRNA codon that would result. (make
sure to capitalize)
Answer: Threonine or Thr.
Explanation:
DNA or deoxyribonucleic acid is a molecule containing genetic information that is passed on from one generation to the next. This molecule is transcribed into another molecule called messenger ribonucleic acid or messenger RNA which is used for protein synthesis in the ribosomes. That is, the one that determines the order in which the amino acids of a protein will be joined. Both RNA and DNA have monomers called nucleotides, composed of a sugar molecule (ribose in RNA or deoxyribose in DNA) linked to a phosphate group and a nitrogenous base. The nitrogenous bases can be adenine (A), thymine (T), guanine (G), cytosine (C) and uracil (U) in RNA replacing T.
A codon is a sequence of three nucleotides found in RNA that codes an amino acid. The genetic code describes the relationship between the sequence of DNA bases in a gene and the corresponding sequence of the protein it encodes. Also note that there is base complementarity between DNA and RNA, that is why DNA is used to make RNA. Complementarity is the ability of the nitrogenous bases in the nucleic acid molecule to combine with their complement, Adenine (A) with Thymine (T) in DNA and A with U in RNA; and Cytosine (C) with Guanine (G) joined by hydrogen bridges.
In the figure, a RNA molecule is shown with the bases, showing which amino acid is code by each codon. In the case where there is a mutation and the G is replaced by an A in the codon coding for alanine, the codon would be ACA coding for threonine or Thr.

How can one use a community in teaching the concept "Safe use of agro-chemicals" to grade six level?
Answer:
A community can be divided into groups, where each group can present the correct ways to use agro-chemicals safely in different types of activity.
Explanation:
Using a community can be very helpful in teaching the safe use of agrochemicals. This is because, as a community usually has a large number of people, these people can be divided into small groups that will serve as small workshop rooms. Within these groups, the different ways to use agro-chemicals in a safe way, both for the applicator and for the environment, will be shown. Information on the composition of agrochemicals, first aid in case of accidents with the use of these products, among other things, can also be presented.

plz can anyone write an essay about water pollution about 1300 words
Answer:
Explanation:
The biological or chemical change in the quality of water due to the presence of contaminants in water is called water pollution. Most of this contamination as on date is due to various human activities. In fact, humans are responsible for the mass deaths of whales and other aquatic organisms often swept ashore at different beaches in the world. There is an urgent need to look into the measures to control water pollution although a lot many efforts and schemes have already been announced by the Government in this regard. To make the students aware of this we have prepared short and long essays for students which shall inform them about water pollution and the means to minimise it.
