Explanation:
if a gene is made up of 20% adenine, how much thymine, guanine, and cytosine will there be
Explanation:
You have 20% of adenine. If you have 20% of adenine than you have 20% of thymine, because the amount of adenine and thymine is equal. 20% plus 20% is 40% of adennine and thymine. From 100% DNA bases subtract 40% and you will get 60%. Then divide this by 2 and you will get 30%. 30% of guanine and 30% of cytosine, because their amounts are equal in the DNA stand.
Eric drops a 3.70 kg water balloon that falls a distance of 20.38 m off the top of a building. What is the velocity at the bottom?
Answer:
The velocity of the balloon at the bottom is 19.99 m/s.
Explanation:
Given;
mass of water balloon, m = 3.7 kg
height of fall, h = 20.38 m
The velocity of the balloon at the bottom is calculated from the law of conservation of energy;
[tex]K.E_{bottom} = P.E _{top}[/tex]
[tex]\frac{1}{2}mv^2 = mgh \\\\ v^2 = 2gh\\\\v= \sqrt{2gh} \\\\v = \sqrt{2\times 9.8 \times 20.38} \\\\v = 19.99 \ m/s[/tex]
Therefore, the velocity of the balloon at the bottom is 19.99 m/s.

Describe the basic histological (tissue) structure of the mucosa layer in the alimentary canal. Identify the unique features of the mucosa in the stomach and the duodenum, and explain how this uniqueness determines the function of the stomach and the duodenum.
Answer: The basic tissue structure of the mucosa layer of the alimentary canal consists of:
--> mucous membrane
--> lamina propria
--> muscularis mucosa
Explanation:
The MUCOUS MEMBRANE forms the innermost layer of the alimentary canals which includes the stomach and the duodenum (small intestine) . It's major functions is protection, secretions and absorption. The type of mucous membrane found in the stomach and duodenum is the Columnar epithelial cells. Not numerous gastric glands are situated below the surface in the mucous membrane of the stomach. They consist of specialised cells that secrete gastric juice that aids in the digestion of food. While the duodenal mucosa consists of mucous producing goblet cells. These cells produce a viscous, alkaline mucus that protects against the acidic gastric juices and pepsin. The folding of these mucosal cells (microvilli) provides a large surface area to optimize nutrient absorption.
The LAMINA PROPRIA: This layer separates the mucous membrane and the muscularis mucosa. It is made up of connective tissues which supports the blood vessels that nourishes the inner epithelial layer. In both the stomach and duodenum, digested nutrients are absorbed into the capillaries.
MUSCULARIS MUCOSA: This is made up of thin layer of smooth involuntary muscles. The contraction and relaxation of these muscle layers occurs in waves, which push the contents of the tract onwards. This type of contraction is called peristalsis which occurs in the duodenum. While in the stomach, these muscles allows for the churning motion characteristic of gastric activities.

a. The mRNA leaves the nucleus and goes to a ribosome open choices for ranking.
b. The building blocks of proteins, are carried to the ribosome by tRNAsAmino acids.
c. Transcription of one DNA strand results in mRNA, which is a complementary copy of the information in the DNA.
Answer:
Explanation:
c. Transcription of one DNA strand results in mRNA, which is a complementary copy of the information in the DNA.
a. The mRNA leaves the nucleus and goes to a ribosome open choices for ranking.
b. The building blocks of proteins, are carried to the ribosome by tRNAsAmino acids.
The process of deoxyribonucleic acod starts with replication to transcription and translation.
Replication involves the formation of a complementary base from a old or template DNA Strand this then serve as a template for transcription.
transcription involves the coping of information on the DNA to an intermediate mRNA ( messanger ribonucleic acid) in the nucleus which then move from the nucleus to ribosome in the cytoplasm where translation occurs.
Translation is the conversion of the information on the mRNA to an amino acid with the help of enzyme transferse ribonucleic acid(tRNA).
Hence the arrangement is from C ---- A-----B.

Describe how plants and animals each contribute to the survival of the other. (This type of cooperative relationship is called interdependence.)
Answer:
Plants produce oxygen which is used by animals in the process of cellular respiration, while animals produce carbon dioxide which is required for plants to make the photosynthesis process
Explanation:
In biology, interdependence can be defined as a mutual dependence relationship among two (or more) taxonomic groups. Animals and plants are cooperatively interdependent because they mutually need each other for different essential aspects of life such as food, respiration, refuge, protection, propagation, etc. For example, plants produce oxygen which is used by animals for cellular respiration (obtaining energy from this process), since most animals are aerobic organisms. Similarly, animals release carbon dioxide (CO2) when they breathe out, and CO2 is used by plants to perform photosynthesis (i.e., to produce energy and carbohydrates from this process).

4. Living things are sometimes called "carbon-based life forms." Do you think this is a good way to describe life? Explain your answer., help me asap
Answer:
Explanation:
Yes, for a couple of reasons.
1. Carbon connects easily with other carbons.
2. Carbon forms chemical that can change and connect with other carbons even in biology or especially in Biology. If you take a brown seen and plant it where it can get water and soil nutrients, to will come up as a green plant. Think about the chemistry that goes into that. Not only that, but there are mechanisms that tell the upper part of the plant that the roots can't supply any more growth. Isn't that something? All made from Carbon.
3. The human body is a mass of Carbon based chemicals and all cells there can have different functions. Amazing isn't it? I'm a fan of the diversity of our planet and its growth.

Since its inception, the theory of evolution has been the subject of frequent debate. Those who oppose evolutionary theory often point to gaps in the
fossil record in an attempt to discredit the theory. Which statement would be the best counterargument as to why the fossil record can be relied upon to
support evolution?
The fossil record provides evidence that extinct species only fossilized during certain geologic eras.
The fossil record provides evidence that extinct species are genetically identical to current species.
The fossil record provides evidence of many different types of organisms, since most species fossilize well.
The fossil record provides evidence of many transitional organisms that show relationships between species
Answer:
There are lots of transitional organisms in the fossil record though it does take very specific and precise conditions for a fossil to be preserved, a deer that dies in a field will not end up in the fossil record so we are looking at a small sampling of the evidence (and a good thing too or there wouldn't be anywhere to walk with all the bones laying around)

The type of weathering seen in the pictures is mechanical weathering.
Weathering is the process by which rocks, minerals, and other geological materials are broken down and altered over time by various physical, chemical, and biological processes. It is a fundamental part of the Earth's surface dynamics and plays a significant role in shaping landscapes.
Mechanical weathering involves the physical breakdown of rocks into smaller fragments without changing their chemical composition. It increases the surface area of rocks, making them more susceptible to further weathering.
