what is overpopulation and how does it effect us?
Answer:
The over loaded of peoples is called overpopulation. There will be more crowded and people will be unemployed and It can effect the global warming
Answer:
Overpopulation is is basically when there is too much of something on our planet or anything else.
When you have a tent that holds 5 people but you put 10 people in it, you would be "overpopulating" the tent. there's such thing as over-farming.
What are researchers doing to great whites in hopes of being able to learn more about their behavior patterns?
Answer:
tagging the sharks
Explanation:
To learn their behavioral patterns researchers are tagging the sharks. Doing so allows the researchers to track their movements individually and gather data as to how they move, where they migrate to, how many migrate together, etc. All this information is extremely valuable and when pieced together can shed light on why they have certain behavioral patterns or traits.
Eutrophication occurs when excess nutrients are supplied to a region, leading to an algae bloom and ultimately
A) ocean deoxygenation
B) coral bleaching
c) ocean acidification
D) overfishing
Answer:
A) ocean deoxygenation
Explanation:
Eutrophication (eutrophication) begins when fertilizers (usually washed away by rain) reach the water from fields and other agroecosystems. Fertilizers are rich in phosphates and nitrates, which are otherwise a limiting factor for the flourishing of life in water.
With an excess of these salts, plants, especially algae, often begin to flourish. Then the number of dead algae increases, which are then decomposed by saprophytes, consuming oxygen. Thus, the concentration of oxygen in the water decreases, and thus there is suffocation and mass death of aquatic organisms that consume oxygen in the process of respiration.

What is the complementary strand to the following DNA below?
YOU WILL GET BRAINLIEST IF YOUR RIGHT
ATTCCGATAA
Answer:
The correct answer is - TAAGGCTATT
Explanation:
The DNA molecule is made up of two strands that make a double helix and each chain of nucleic acid sequence known as an individual strand that is composed of a complementary base bound with another strand bases.
Adenine is complementary to thymine similarly cytosine to guanine and vice versa so the complementary strand of the given would be as follows:
DNA strand- ATTCCGATAA
Complemntary strand - TAAGGCTATT

acrostic of planets
Answer:
You can combine the acronym and acrostic methods. The first four (inner) planets, in order from the Sun, are Mercury, Venus, Earth, and Mars. ... Now consider the acrostic: "My very easy mnemonic. Just spin us nine planets." You can memorize two sentences and use the first letter of each word to help you think of planets.
Answer:
To remember the planets, you can create an acrostic from the first letter of each planet, like "My Very Educated Mother Just Served Us Nachos"
Explanation:
The products that plants produce in photosynthesis are different from the products that animals and some bacteria produce in cellular respiration. The products of photosynthesis are
Answer: Carbohydrates in the form of glucose and oxygen as byproduct.
Explanation:
Photosynthesis is a process which occurs in green plants and in other autotrophs. In this process the autotrophs can prepare their own food by using reactants like water and carbon dioxide to produce glucose which is a carbohydrate which a major source of energy for plants and oxygen gas is released as a byproduct of this chemical reaction. On the contrary to this the cellular respiration can be defined as the process in which the biochemical oxidation of food occurs and energy is released in the form of ATP and carbon dioxide and water are produced.
Thus in photosynthesis the carbon dioxide and water are the reactants whereas in cellular respiration they are the products.
Which is a reactant in the Calvin cycle?
A. Glucose
B. Oxygen
C. Carbon dioxide
D. Water
The reactant of the Calvin cycle is the carbon dioxide that is present in Option C, and the product of the Calvin cycle is glucose. The Calvin cycle takes place during the photosynthetic reaction.
What is the role of photosynthesis?Photosynthesis is a process in which the plant plays an important role, such as when the plant absorbs the sun's light, water, and carbon dioxide and then produces oxygen and glucose by combining all of these elements; thus, glucose and oxygen are the products, and water and carbon dioxide are the reactants. The water is used in the light-dependent reaction and converted into oxygen as a product, while in the case of the Calvin cycle or the light-independent reaction, carbon dioxide is used as the reactant and the product that is formed is glucose.
Hence, the reactant of the Calvin cycle is the carbon dioxide that is present in Option C.

The appearance of the pink color was due to the movement of a. phenolphthalein molecules from low concentration to high concentration b. base molecules from high concentration through the membrane to low concentration c. water molecules through the membrane from high concentration to low concentration d. phenolphthalein molecules in the water from high concentration to low concentration
Answer:
b. base molecules from high concentration through the membrane to low concentration
Note: the complete question is found in the attachment below
Explanation:
The process which enabled the color change in the water and phenology mixture is known as diffusion.
Diffusion is the movement of molecules from regions of higher concentration to regions of lower concentration until equilibrium concentration is attained.
In the setup by the student, the concentration of the base molecules are higher in container than in the test tube. The vaporized molecules of the base therefore, moved through the membrane into the water and phenolphthalein mixture, resulting in the color change to pink in the mixture due to the reaction of the base and the phenolphthalein.

18. During meiosis, homologous chromosomes exchange genetic material. This exchange of
genetic material -
A. increases the genetic variation
B. reduces the diploid number to the haploid number
C. increases the haploid
number to the diploid number
D. reduces the probability of mutations
A. increases the genetic variation
that's why individuals don't look like their partents. This process is called crossing-over
During meiosis, homologous chromosomes exchange genetic material. This exchange of genetic material - A. increases the genetic variation.
During meiosis, homologous chromosomes may exchange genetic material during a process called "crossing over."
Crossing over takes place during the pachytene stage of Prophase I of Meiosis I where the non-sister chromatids of homologous chromosomes exchange genetic materialthis results in recombination of the genetic material and creates a new genetic combination. This results in variations, which can be beneficial to the offspring providing a better survival advantage.So, the correct answer is Crossing over produces new combinations of genes on alleles, increasing genetic variation.

You have a piece of DNA containing the gene for green fluorescent protein (gfp) and the pBAD promoter. This DNA fragment has been cleaved with BamHI and HindIII and can be inserted into either the pKAN-R plasmid or the pARA plasmid. Which plasmid would you choose to use as the plasmid vector to express gfp protein in bacterial cells
Answer:
pARA plasmid
Explanation:
Plasmids are natural circular DNA samples found in bacteria cells. There are two types of plasmids founds in bacteria cells namely; pARA and pKAN-R.
The pKAN would not be maintained in the cell during replication but the pARA plasmid would and when the DNA fragment is inserted, the pARA would serve as a catalyst for the gfp protein.

A student looks at his cell under a microscope which of the following observations would indicate the cell is from a plant rather than an animal
Answer:
Chloroplasts in the cytoplasm of the cell
Explanation:
The options you were given are the following:
nucleus is located inside of the cell numerous cilia on the outside of the cell chloroplasts in the cytoplasm of the cell a thin membrane around the edge of the cellThe organelles that would indicate that the observed cell belongs to a plant rather than an animal are chloroplasts. Chloroplasts are organelles that conduct photosynthesis - a process in which plants (and some other organisms that possess chloroplasts) get food. In this process, with the help of sunlight, plants transform carbon dioxide, water, and minerals into oxygen, which is released into the atmosphere, and glucose, which they feed on.
Both animal and plant cells have a cell membrane and the nucleus located inside of them.
The cilia are usually found in animal cells.
This is why the third option is the correct one.
