Two questions:
1. What are the 2 major functions of proteins?
2. Describe the structure of proteins.

Answers

Answer:

1.  It helps repair and build your body's tissues and it also provides your body with a structural framework.

2.  Protein structure is the three-dimensional arrangement of atoms in an amino acid-chain molecule.

Explanation:

Answer:

1-Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body's tissues and organs.

2-The overall structure of the protein includes both alpha helices (green) and beta sheets (red). The primary structure of a protein — its amino acid sequence — drives the folding and intramolecular bonding of the linear amino acid chain, which ultimately determines the protein's unique three-dimensional shape.

How does the structure of DNA explain chargaff's rule?

Answers

Answer:

Chargaff's rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio (base pair rule) of pyrimidine and purine bases and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine

Chargaff's Rule explains that in the natural DNA, the total number of guanine equals to the number of cytosine and the total number of adenine equals to the number of thymine. This tells about the base pair composition of DNA molecule.

What is Chargaff's rule?

Chargaff's rule states that in the DNA molecule of any species or organism, the total amount of guanine residues should be equal to the amount of cytosine residues and the amount of adenine residues should be equal to the amount of thymine residues. A stoichiometric ratio of 1:1 of purine and pyrimidine bases i.e., A + G = T + C should be fulfilled.

Chargaff's rule describes the ratio of the various nitrogenous bases present in the DNA molecule. It aids in the determination of the structure and composition of DNA in living organisms. It is constant for a species.

- Use what you have learned about dominant and recessive alleles to explain why Ravyn
is albino when neither of her parents is abino?

Answers

Answer:

Please find the explanation as to why Ravyn is albino when neither of her parents is abino below

Explanation:

According to Gregor Mendel in his law of dominance, a DOMINANT allele is a form of a gene (allele) that masks the phenotypic expression of another in a gene while the RECESSIVE allele is the allele being masked. This means that an allele can be present in a gene but in a masked or recessive condition.

According to this question, Ravyn happened to be an albino when neither of her parents is albino because BOTH of his PARENTS are HETEROZYGOUS for the skin color trait i.e. they both contain the allele for normal skin color, which is dominant, and the allele for albinism, which is recessive. Note that a recessive trait will only express itself when in a pure breed condition, hence, both parents contributed the reccesive allele (albinism) to produce the recessive condition in Ravyn.

In a nutshell, Ravyn is an albino because his parents are heterozygous and both passed on the recessive alleles to him.

Which two factors are most likely to cause a plant's guard cells to open its stomata?
A. Increased gravitational pull I
B. Increased sunlight
C. Increased rainfall
D. Increased turgor pressure​

Answers

the correct answers are B and D

the increased sunlight will determine the guard cells to start photosynthesis, this will result in an incresed glucose concentration inside the guard cells .The increased glucose concentration will cause osmotic pressure to build up, so the guard cell will absorb water from neighbouring cells, this will cause increased turgor pressure that will deform the cells in order for the stomata to open

Answer:

D. Increased turgor pressure​

B. Increased sunlight

If the forces acting on two objects are the same, which object has greater acceleration? An object that is 200 kg or an object that is 400 kg? Text to speech

Answers

Answer:

Object with 200kg

Explanation:

Newton's second law of motion depicts how the acceleration of an object depends on the force (F) and mass of the object (m). This law can be represented by the mathematical equation: F = ma

However, the acceleration of the object is inversely proportional to the mass i.e. a = F/m. This means that an increase in the mass of an object causes a decrease in acceleration of the object and vice versa.

According to this question, If the forces acting on two objects are the same, an object that is 200 kg will have a greater acceleration than an object that is 400 kg. Note: the higher mass the mass, the lower the acceleration and the lower the mass, the higher the acceleration.

Because biological systems are generally held at constant temperature and pressure, it is possible to predict the direction of a chemical reaction by measuring which of the following?

a. ATP concentration
b. Enthalpy
c. Entropy
d. Free energy

Answers

I think it is B hope this helped

Because biological systems are typically maintained at constant temperature and pressure, calculating the free energy of a chemical reaction allows one to predict the reaction's direction that is in option d.

What role does free energy play in the biological system?

In a biological system, the free energy is very significant, where the free energy is the amount of energy that is needed by the cells of the body to perform the function, and the negative free energy indicates that the reaction is exothermic and this energy can be used for other processes. The process where free energy is needed, known as endothermic process, must be completed when there is positive free energy.

Hence, because biological systems are typically maintained at constant temperature and pressure, calculating the free energy of a chemical reaction allows one to predict the reaction's direction that is in option d.

This means the monarch is the ceremonial leader, but Parliament makes the laws. Unlike the United States Constitution, the British constitution is not a single document, but a group of laws and court decisions. The symbolic head is Queen Elizabeth II, who symbolizes Britains nationhood.The British legislature, or Parliament, is located in London, England. It is made up of the House of Lords and the House of Commons. At one time, members of the House of Lords inherited their seats. Today, Parliament is moving toward a combination of elected and appointed members in both houses. These members are composed of high-ranking clergy, judges, and national leaders. The head of the majority party in the House of Commons is the prime minister, the true head of the British government.Which statement best explains why the British system of government is considered a constitutional monarchy?Responses A. A king or queen is the head of state, but Parliament makes the laws. B. Some members of Parliament are elected, while others are appointed. C. The monarch has more power than the elected parliament.

Snowball did not deny that to build it would be a difficult business. Stone would have to be carried and built up into walls, then the sails would have to be made and after that there would be need for dynamos and cables. (How these were to be procured, Snowball did not say.) But he maintained that it could all be done in a year. And thereafter, he declared, so much labour would be saved that the animals would only need to work three days a week. Napoleon, on the other hand, argued that the great need of the moment was to increase food production, and that if they wasted time on the windmill they would all starve to death. The animals formed themselves into two factions under the slogan, "Vote for Snowball and the three-day week and "Vote for Napoleon and the full manger."Why does Snowball want to build a windmill?He wants to compel the animals to work harder.He wants to increase food production immediately.He wants to find a use for the stone on the farm.He wants to make the farm run more efficiently.
