If Tom Harris had type AB blood and Mary had type O, could the type O child they brought home be their child? * No, the baby would have to have inherited a gene for O from both parents and Tom has only a gene for A or B. Yes, both parents had the recessive hidden gene for O blood in their genotype which they passed on to the baby. No; the baby would have to have Type AB blood that it inherited from the father since A and B are dominate to O. Yes; the baby inherited type O blood from the mother Mary Harris which is dominant to the genes for both A and B.

Answers

Answer 1
Answer:

The study of blood is called hematology. The component of blood is RBC, WBC, platelets, and plasma.

The correct answer to the question is option B.

What is a blood group?

  • A blood type is a classification of blood, based on the presence and absence of antibodies and inherited antigenic substances on the surface of red blood cells.
  • These antigens may be proteins, carbohydrates, glycoproteins, or glycolipids, depending on the blood group system.

The genes A and B are dominant over O therefore the O blood group can not be seen in offspring.

Hence, the correct answer to the question is option B is Yes, both parents had the recessive hidden gene for O blood in their genotype which they passed on to the baby. No; the baby would have to have Type AB blood that it inherited from the father since A and B are dominant to O.

Answers

Answer:

Cell, tissue, and organ.

Explanation:

A cell is an obvious one because it makes up the tissue, and it is needed in order to form an organ. Meaning tissue and cell would have to be included. Tissues witch are made of many cells form an organ, and an organ would be  the human stomach/digestive system. It can't be organ system because a stomach can't be a whole system including the heart and ect. It can't be organism because a stomach isn't enough organ systems to create an organism.

How many hydrogen bonds will be involved in base pairing in a DNA molecule of 50 base pairs that contains 15 cytosine bases

Answers

Answer:

The number of hydrogen bonds involved will be 39

Explanation:

There are 4 types of bases that exist in a DNA, which are adenine, thymine, guanine and cytosine. Double stranded DNA molecules have these bases attaching specifically to one another; adenine only binds to thymine and vice versa while guanine only binds to cytosine and vice versa. These two bases bonding together are referred to as base pairs and the type of bond here is the hydrogen bond. There are double bonds between the adenine and thymine base pair while there are triple bonds between the guanine and cytosine base pairs.

Thus, when there are 13 cytosine bases in a DNA molecule, the number of hydrogen bonds present in the resulting base pairs will be 13 × 3 (because cytosine binds with a triple bond to guanine).

13 × 3 = 39

The number of hydrogen bonds involved will be 39

Final answer:

So, in a DNA molecule of 50 base pairs that contains 15 cytosine (C) bases, there would be a total of 115 hydrogen bonds involved in base pairing.

Explanation:

In DNA, base pairing occurs between complementary nitrogenous bases. Adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). Each base pair is connected by hydrogen bonds.

In a DNA molecule of 50 base pairs with 15 cytosine (C) bases, you can determine the number of hydrogen bonds involved in base pairing as follows:

1. Each adenine (A) pairs with thymine (T) and forms two hydrogen bonds.

2. Each cytosine (C) pairs with guanine (G) and forms three hydrogen bonds.

So, for the 15 cytosine (C) bases, you would have 15 pairs of C-G base pairs, and for the remaining 35 bases, you would have 35 pairs of A-T base pairs.

Total hydrogen bonds involved in base pairing:

(15 pairs of C-G base pairs * 3 hydrogen bonds per pair) + (35 pairs of A-T base pairs * 2 hydrogen bonds per pair)

= (15 * 3) + (35 * 2)

= 45 + 70

= 115 hydrogen bonds.

So, in a DNA molecule of 50 base pairs that contains 15 cytosine (C) bases, there would be a total of 115 hydrogen bonds involved in base pairing.

Nicotinamide adenine dinucleotide phosphate (NADP ) is a biological oxidant involved in the oxidation of testosterone to estradiol.True/false

Answers

Answer:

False.

Explanation:

NADP does not  convert  testosterone to estradiol. This oxidation  is done by a steroid   17-a-hydroxysteroid dehydrogenase.

This oxidation  is essential for stability of hormone: it helps to regulates the elevation of Testosterone in women,subduing the manifestation of male sexual characteristics,

and

for preventing autoimmune diseases.

The oxidation involved two basic  steps of  reaction, controlled by two different enzymes.

NADP is a Co- factor,  when in reduced form( NADPH) is used in Calvin cycle, of light independent reaction of photosynthesis, and in Nucleic acid and triglycerides synthesis.

It has nothing to do with conversation of Androgen( testosterone  to Estradiol.

All of these processes help a cell maintain homeostasis except:A. making new molecules for growth.
B. transporting oxygen across the cell membrane.
C. breaking down unneeded molecules.

D. taking in wastes from other cells

Answers

Final answer:

The correct answer is D. taking in wastes from other cells.

Explanation:

The correct answer is D. taking in wastes from other cells.

Homeostasis is the process by which cells, organisms, or systems maintain stable internal conditions. To achieve and maintain homeostasis, cells perform various processes such as making new molecules for growth, transporting substances across cell membranes, and breaking down unneeded molecules. However, taking in wastes from other cells does not contribute to maintaining homeostasis and is not a recognized process for this purpose.
