Describe mechanism of blood circulation.
Answer:
Look down!! ;)
Explanation:
Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body's tissues through the aorta.

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
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.

A _______________ from the sun hits chlorophyll and excites an electron, known as __________________________________.
Answer:
Photon, light dependent reaction of photosynthesis
Explanation:
Photosynthesis is the process by which green plants make their own food in the presence of sunlight and water.
There are two steps of Photosynthesis that include light dependent reaction and light-independent reaction.
In light dependent reaction, a photon from the sun is absorbed by the green pigment in leaves called chlorophyll that allow the electron to excite from ground energy level to high energy level. It converts the solar energy into chemical energy and called light dependent reaction of photosynthesis.
Hence, the correct answer is "Photon, light dependent reaction of photosynthesis".
- Use what you have learned about dominant and recessive alleles to explain why Ravyn
is albino when neither of her parents is abino?
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.

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
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.

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