A scientist is extracting the DNA of a multicellular organism. He finds that 20% of the strands bases are Thymine. Based on Chargaff's rule, what percentage of the
strands bases would be Adenine?
A. 20%
B. 70%
C. 40%
D. 60%
Answer:
A. 20%
Explanation:
A DNA molecule consists of four nucleotides viz: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). According to Chargaff in his complementary base pairing rule, these nucleotides pair with one another in such a way that A bonds to T, while G bonds to C.
Based on Chargaff's rule, the amount of Adenine in the DNA is equal to the amount of Thymine while the amount of Guanine is equal to that of Cytosine i.e. A=T, G=C.
A + T + G + C = 100%
Hence, in this question, a scientist finds that 20% of the strands bases are Thymine. This means that the amount of Thymine in that DNA will also be 20%. S
Since A=T = 20% in accordance to Chargaff rule.

PS: Love you babe ill see you when you get home.
A dry soil sample has a volume of 500 mL. After 400 mL of water are added to the soil, the soil becomes saturated with 150 mL of surface water left on top. The porosity of the soil is 50%. Thus, option C is correct.
What is Forest soil?Forest soil has more moisture than sandy soil therefore the types of plants that are grown in soil of forests are more qualitative and more superior than the sandy plants which are facing certain limitations and facing certain situations.
Forest soil supports plant life, but sandy soil does not support any plants. Forest soil produces more superior life and the plants life are found in the forest area and the sandy plants are lesser found in the sandy areas.
The reason for vegetation in forests is because of the supportive factors that are involved in the good plants life. The soil type that is the richest in organic material would be a dark-colored soil. Decaying matter turns brownish-black which makes this type of soil having a dark color even almost black.
Therefore, A dry soil sample has a volume of 500 mL. After 400 mL of water are added to the soil, the soil becomes saturated with 150 mL of surface water left on top. The porosity of the soil is 50%. Thus, option C is correct.

What part(s) of photosynthesis would the plant not be able to perform if there were no rain?
Answer:
When plants are not watered properly they wilt. ... When a plant is properly hydrated, there is enough water pressure to make the leaves strong and sturdy; when a plant doesn't get enough water, the pressure inside the stems and leaves drops and they wilt. Plants also need water for photosynthesis.
Plants wilt when they are not adequately watered. When a plant receives enough water, the water pressure inside the stems and leaves rises and causes the plant to flourish.
What is photosynthesis?The process by which plants convert carbon dioxide, water, and sunshine into oxygen and sugar-based energy is known as photosynthesis.
When a plant does not receive enough water, the water pressure inside the stems and leaves decreases and the plant wilts. Water is also required by plants for photosynthesis.
Photosynthesis is essential to most life on Earth. Plants, algae, and some types of bacteria carry out the process by capturing solar energy to create oxygen (O2) and chemical energy stored in glucose (a sugar).
Therefore, Plants wilt when they are not adequately watered. When a plant receives enough water, the water pressure inside the stems and leaves rises and causes the plant to flourish.

Answer:
Force, F = 90 N
Explanation:
Given that,
Mass of the bicycle and rider, m = 60 kg
Acceleration of the bicycle and rider, a = 1.5 m/s²
We need to find the force acting on the bicycle and rider to accelerate. Let it is F. Its force is given by :
F = ma
F = 60 kg × 1.5 m/s²
F = 90 N

Answer: (Structure) mRNA: always single stranded, rRNA: single stranded, twisted upon itself in some regions, tRNA: cloverleaf-like structure
(Function) mRNA: carries the information in the DNA to the ribosomes where it is translated into amino acids of proteins, rRNA: helps assemble tRNA, mRNA, and amino acids to form the polypeptide chain during protein synthesis, tRNA: acts as an adaptor molecule, which identifies correct amino acids corresponding to the anticodon present on it
Explanation: Plato, you're welcome
(Structure) mRNA: always single stranded, rRNA: single stranded, twisted upon itself in some regions, tRNA: cloverleaf-like structure.
(Function) mRNA: carries the information in the DNA to the ribosomes, rRNA: helps assemble tRNA, mRNA, and amino acids to form the polypeptide chain, tRNA: acts as an adaptor molecule.
What is mRNA, rRNA and tRNA?mRNA carries instructions from the DNA to the ribosome work site. rRNA forms part of the structure of the ribosome and helps to connect pieces together. tRNA brings in the amino acids, which are the pieces that get strung together to make the final protein.
Moreover, the three major types of RNA are: mRNA (messenger RNA) : it provides the template for protein synthesis during translation, tRNA (transfer RNA) : it brings amino acids and reads the genetic code during translation, rRNA (ribosomal RNA) : it plays a structural and catalytic role during translation.
Therefore, the main difference between mRNA and tRNA is that mRNA serves as the messenger between genes and proteins whereas tRNA carries the specified amino acid into the ribosome in order to process the protein synthesis.

( please, do not comment if you do not know the answer, I will give Brianlist ) Please complete the following:
1. You and Tim, who is larger than you are outside with a wagon. Tim (the bigger person) gets in the wagon and you (the smaller one) pull it. As you pull
it, you accelerate until you reach a comfortable velocity. Then you stop and switch places with Tim. Tim now pulls you in the wagon, accelerating
from a stop to a comfortable velocity. Now, Tim may be bigger than you, but you have been working out and are just as strong as Tim, so the force
that Tim uses to pull the wagon is the same force that you used. You both pull with the exact same amount of force. Who was riding in the wagon
when it had the greatest acceleration during start up? Why? Use Newton's second law to explain.
2. Now Sara comes along, and she is the exact same size as you. However, she is even stronger than you! When she pulls you in the wagon, she pulls
with a greater force than when you pull her. Now who is in the wagon when it has the greatest acceleration? Explain, using Newton's second law.
Answer:
2. Sarah
Explanation:
because she is stronger, she is able to pull faster and easier because of the amount of weight she can carry vs the amount of weight you can carry. Although you are the same height, she has more muscle.
There are two forms of diabetes. Type II diabetes is also known as late-onset diabetes because it typically affects adults. Consider the following information about Type II diabetes:
Studies have shown that the lifetime risk for developing Type II diabetes is 40% for individuals who have one parent with Type II diabetes.
If a person has two parents with Type II diabetes their risk rises to 70%
Other factors that affect your risk for Type II diabetes include obesity, a sedentary lifestyle (not moving around much), a small or large birth weight, and stress.
Use the information above to answer the question: Is your risk of having Type II diabetes due to your genes, or due to the influence of the environment on your genes (epigenetics), or both?
Answer:
Both
Explanation:
As explained in the passage wether your mom or dad or both have had type ll diabetes in the past determines your risk of having it as well which is part of your genes. But also the influence of the environment on your gene is also a cause to type ll diabetes . Some people would rather stay inside rather than get exercise or some people would rather eat candy or sweets for breakfast or dinner all these things are causes of type ll diabetes which they are caused by the influence big the environment on your genes.

When a person eats the yogurt, the 14 grams of protein will be A combined into monosaccharides. B combined into polysaccharides. C broken down into amino acids. D broken down into nucleic acids.
Answer:
C broken down into amino acids.
Explanation:
Proteins are one of the four major biological molecules. They are organic polymers made up of monomers called AMINO ACIDS. Proteins are contained in food we ingest and are subsequently digested or broken down into their amino acid components.
In this case, when a person eats yogurt (containing proteins), the 14 grams of protein will be broken down into amino acids during digestion by enzymes called PROTEASES. Note that every polymer will be broken down into its monomeric constituents during digestion.
Shoot the Golgi Apparatus. Fill in the blanks: Golgi receives ANSWER containing ANSWER that were sent by the ANSWER Then it modifies ANSWER and send them where they need to go.
Answer:
Golgi receives a vesicle containing newly synthesized proteins that were sent by the endoplasmatic reticulum. Then it modifies the proteins and sends them where they need to go.
Explanation:
Protein synthesis is initiated in the cytoplasm when mRNA meets a free ribosome, which is the primary structure for protein synthesis. They read the mRNA code and add the correct amino acid using transference RNA to build the protein. The synthesizing protein is driven to the rough endoplasmic reticulum and translocated to the lumen. Once there, the protein suffers a few modifications, one of them is folding to become functional. Once membrane proteins are folded in the interior of the endoplasmic reticulum, they are packaged into vesicles and sent to the Golgi complex, where it occurs the final association of carbohydrates with proteins. The Golgi complex sends proteins to their different destinies. Proteins destined to a certain place are packaged all together in the same vesicle and sent to the target organ. In the case of membrane proteins, they are packaged in vesicles and sent to the cell membrane where they get incrusted.
