In your letter, you need to explain how the theory of evolution is supported by evidence. Be sure to include the 4 pieces of evidence for evolution as well as an example of each.
Answers
The evidence of evolution was posited by Charles Darwin. The theory of evolution states that all species are related and that they change over time
The different postulates of Drawin support the natural selection phenomenon. Darwin stated that the organisms that are fit and are able to change according to evolution are able to survive. This was known as the survival of the fittest.
The evidence of the evolution can be studied by fossil record , comparative embryology , molecular biology , and comparative anatomy.

Aspirin makes the blood thinner and prevents blood clotting which causes heart attack. i) What type of rupture did Suman suffer from? ii) What did the doctor advise her to do? Why do you think so? iii) What is the cause of Amit's heart attack? iv) Why do doctors give Aspirin to the heart patient?
Answers
Answer:
Aspirin is administered in patients who produce blood hypercoagulation, that is why it is prescribed in order to antiaggregate platelets or platelet thrombi, this is how the platelets do not add or encompass each other and do not generate obstructions in the blood vessels to trigger an AMI (acute myocardial infarction) or CVA (cerebrovascular accident.)
Explanation:
Aspirin is an anticoagulant that is made up of N acetylsalicylic acid, that is, by an acid that inhibits the union of platelets with each other, that is why these in systemic situations where there is a tendency to hypercoagulation of the blood is a benefit for the patient .
Amit's infarction is caused by a platelet thrombus that obstructs the arterioles that supply the cardiac muscle tissue, that is, the coronary arteries. When these arteries are blocked by a platelet engulfment, the irrigation does not oxygenate the tissue and it suffers a transient hypoxia or anoxia that leads to partial necrosis and even in some cases of more serious situation it could be total where the person loses his life.

Garden Care
By
Mary Simpson
This flower must have grown in neutral soil, with little aluminum.
In some varieties of bigleaf hydrangeas (Hydrangea macrophylla), soil pH determines whether the plant will produce blue or pink flowers. Blooms appear bluest when grown in acidic soil with a pH in the 5.0 to 5.5 range. The same cultivar may sport pink blossoms in soil with a more neutral pH, such as 6.5 to 7.0. Florists control flower color by potting soil mixture

What technology helps her to stay in her home safely?The technology that can help her stay in her home instead of moving to a nursing home is a medical-alert bracelet that informs first responders of a fall or an emergency.

Asexual reproduction is a mode of reproduction in which a new offspring is produced by a single parent. The new individuals produced are genetically and physically identical to each other, i.e., they are the clones of their parents.
In asexual reproduction, one parent copies itself to form a genetically identical offspring. Sea turtles are an example of an animal that reproduces sexually, a volvox (green algae) is an example of an organism.

Answers
Answer:
Amino acids
Explanation:
Proteins are made up of amino acids which come together to form polypeptide chains.
The organic molecule that is closely related to proteins are amino acids. The correct option is B.
What are amino acids?Amino acids are molecules that form proteins when they combine. The fundamental components of life are amino acids and proteins.
Amino acids are left over after proteins are digested or broken down. To help the body, the human body uses amino acids to make proteins: Food should be broken down.
Isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, valine, cysteine, tyrosine, histidine, and arginine are the 12 amino acids.
An amino acid is an organic molecule composed of a basic amino group, an acidic carboxyl group, and a unique organic R group (or side chain) for each amino acid. Alpha-amino carboxylic acid is the chemical formula for amino acids.
Thus, the correct option is B.

One side of the water molecule has a positive charge, while the other side has a negative charge. What do the charges indicate about the molecule?
Answers
Answer:
That its a nuetral
Explanation:
In the given case of water molecule, the charges shows that it is a polar molecule.
What is a polar molecule?It is a molecule in which one terminal of the molecule is slightly positive and the other terminal is slightly negative. In the case of water molecule, the unequal sharing of electrons provides the molecule with a slight negative charge close to its oxygen atom and a slight positive charge close to its hydrogen atoms.
When a neutral molecule, possesses a positive region at one terminal and a negative region at the other, it is considered as a polar molecule. The molecules of water attract each other on the basis of the positive end of one water molecule and the negative end of the other molecule of water.
Thus, the charges shows that it is a polar molecule.

Answers
Answer:
D). different due to independent assortment during meiosis
Explanation:
Gametes that an organism produces accommodates a blend of genes of that organism and in each gamete, this blend or combination is 'distinct and that is due to independent assortment during meiosis.' It implies that the chromosomes pass randomly for isolation of poles during the division of cells at the time of the process of meiosis and this independent segregation causes each gamete to contain a unique combination of genetic code.
