Newton's 2nd Law is F= ma. Write a problem that gives the mass and the acceleration of an object and asks us to find the force.

Answers

Answer:

An object having a mass of 20kg is pushed by John and it then accelerates down the inclined plane at a rate of 0.5m/s². Find the force applied on the object.

Explanation:

Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.

For example, an object having a mass of 20kg is pushed by John and it then accelerates down the inclined plane at a rate of 0.5m/s². Find the force applied on the object.

Given the following data;

Mass = 20kg

Acceleration = 0.5m/s²

To find the force;

Force = mass * acceleration

Substituting into the equation, we have;

Force = 20 * 0.5

Force = 10 Newton.

The first generation of hybrid offspring is called the ______ and can often be used to determine the ____ gene.
a. F2 generation; h.o.m.o.z.y.g.o.u.s.
b. F1 generation; h.o.m.o.z.y.g.o.u.s.
c. P generation; dominant
d. F1 generation; dominant

(Brainly needs to realize if they let us talk about college biology, that we are going to use words that have h.o.m.o. and that they are genuinely correct scientific terms.

Answers

P is parent gene, and then the offspring goes to the F1 and then F2, the dominant gene is what gene wins over a recessive. So the answer is c

The preferred generation of hybrid offspring is called the P generation and can often be used to determine the dominant gene.

What is P generation and dominant?

Dominant directs to the relationship between two versions of a gene. Then, Individuals receive two versions of each gene, which are called alleles, from each parent. When the alleles of a gene are different, So, one allele will be expressed This is a dominant gene.

When The P generation is the start of Mendel's work on inheritance, or receiving genetic qualities by transmission from parent to offspring. So, Basically that it refers to traits or genes that are passed from a parental generation to its offspring

When P is the parent gene, and also then the offspring goes to the F1 and also then F2, the dominant gene is what gene wins over a recessive. So the correct option is 'C'.

Two women gave birth in the same hospital on the same afternoon. Their babies were taken
away, and then brought back to them one hour later. One of the women was worried that

Answer:

Explanation:

If the Husband of Woman One had group O blood, than It would be hard for Woman 2's baby to have group O blood, because the Parents of Baby 2 are AB and A. So the hospital did give the woman the right babies

They were given the right baby cause the women who was worried her husband was group o and the baby they got was group o and the other women had a child with group b and her blood was a and b so yes it’s correct

Radioimmunoassay (RIA) of peripheral blood indicated elevated TSH levels. A TSH stimulation test did not increase the output of thyroid hormones from the thyroid gland.

a. What endocrine organ is involved here?
b. Is this a primary or secondary disorder? Why? (Is a TSH or TRH determination necessary for your diagnosis?)
c. Describe the feedback loop involved, indicating if there is an increased or decreased TSH level.
d. List several defects that could cause these symptoms.
e. Would you expect to find a palpable goiter? Explain your answer.
f. Describe a suitable treatment for this individual.

Answers

Answer:

1. Thyroid gland is the endocrine gland that is involved here.

2. TSH stimulation test did not show an increase in the output of thyroid hormones secreted from thyroid glands which makes it a primary disorder. The determination of TSH or TRH gives an idea about hypothyroidism if it is due to feedback inhibition of the pituitary or absence of TSH hormone from the pituitary, however, Circulating levels of TRH not necessary.

3.  The feedback loop involves the following:

TRH hormone secreted from the hypothalamus triggers the anterior pituitary to secret TSH that in turn triggers the relapsing of the T3 and T4 levels by the thyroid glands. If there is a low level of T3 and T4 hormones then negative feedback takes place and increases the TSH output.

4.  symptoms:

Not able to uptake the iodide into the cells of the thyroid gland

Defects in the conversion of iodide to iodine

tyrosine molecule iodization

secretion of the hormones from the Tg molecules

Less TSH receptors on the gland.

5.  The chronic TSH stimulation due to negative feedback may cause hypertrophy of the gland, results in goiter formation.

6. synthetic hormone therapy is known as Synthroid such asT4 (L-thyroxine).

If a DNA strand contains 12% thymine, it also contains ____

a. 12% A, 38% G, 38% C
b. 12% A, 12% G, 38% C
c. 12% A, 12% G, 12% C
d. 38% A, 12% G, 38% C

Answers

Answer:

If G = 14, then C = 14 and G + C is 28. Thus A + T. The percent of adenine in a double-stranded DNA is 38. Therefore G + C = 100 - 76 = 24, and C = 24/2 = 12 percent.  

Explanation:

A=T
so A is 12% too
100-(12+12)
=100-24
=76
then divide by 2 to get each C and G
76/2=38
so C and G are each 38%

the answer is option A
