Mammals reproduce through a process called sexual reproduction. During this process, which involves two parents,A. a female egg cell combines with a male sperm cell to make an offspring that is identical to one of the parents.

B. a female egg cell and a male sperm cell each develop separately into an offspring that is different from both parents.

C. a female egg cell and a male sperm cell each develop separately into an offspring that is identical to its parent.

D. a female egg cell combines with a male sperm cell to make an offspring that is different from both parents.

Answers

Answer 1

Answer: D. a female egg cell combines with a male sperm cell to make an offspring that is different from both parents. Gametes are produced by meiosis, and the source of genetic variation during sexual reproduction comes from crossing over of tetrads at chiasma during prophase I, independent assortment, and random fertilization. These gametes (egg and sperm) then combine to form a genetically different offspring.

What is the RNA sequence that will be formed from the DNA sequence: GGCTATTC?a. GGCUAUUC
b. CCGAUAAG
c. CCGUAUUG
d. CCGTUTTG

Answers

The correct answer is B.

According to base pairing rules, A will always pair with T and and G will always pair with C. This pairing happens in DNA.

When it comes to RNA, there is a slight difference. Thymine is never found in RNA but is replaced with Uracil. So instead of Adenine pairing with Thymine, it will be Uracil which takes the place of Thymine.

It is important to note that Thymine in DNA will code for Adenine in RNA because Adenine is found in RNA base sequence. However whenever Adenine in DNA wants to code for a complementary base to copy on RNA, then Adenine will call for Uracil, not Thymine.

What distinguishes high blood pressure from conditions such as arteriosclerosis and atherosclerosis?

Answers

High blood pressure is a condition in which blood makes pressure on artery walls. It usually has no obvious symptoms, unless it is very high, and the only way to find out if high blood pressure is present is to measure it.

Arteriosclerosis is a condition in which blood vessels become thin and stiff. Atherosclerosis is a condition in which cholesterol, fats, and other substances build plaque inside the arteries. In both cases, blood flow is affected.

Which compound is also a carbohydrate?A) enzyme
B) lipid
C) salt
D) starch

Answers

Starch, or asylum, is a complex carbohydrate that exists in many foods, including grains, vegetables, and fruits. Thus, option D is correct.

What is carbohydrate ?

The body's primary energy source is carbohydrate-based. They are the dietary fibre, sugars, and carbohydrates found in dairy and plant-based diets. Carbohydrates have carbon, hydrogen, and oxygen atoms in their chemical makeup. Aldehydes, which are double-bonded carbon and oxygen atoms plus one hydrogen atom, and aldehydes, which are double-bonded carbon and oxygen atoms plus two more oxygen atoms, are the two basic molecules that make up carbohydrates.

It is a carbon atom-containing ketone. Different forms of carbohydrates can be produced by combining carbs to form polymers or chains. Monosaccharides, disaccharides, and polysaccharides are all types of carbohydrates.

D) starch
enzymes could be nearly anything lipid is a separate category and salt is not a carb so that leaves starch which is the answer (also it is a compound so nothing to doubt here!)
