if a colour-blind male marries a female carrier of colour-blind, what is the probability of the couple getting a colour-blind son?

Answers

1/16 because it is a 1/2 chance their child is a son 1/2 they have a daughter another 1/2 chance if their son is color blind and another 1/2 they have a color blind daughter. I hope this helps :) 1/2 * 1/2 * 1/2 * 1/2 = 1/16

There is 100% that the offspring will be colorblind

Jasmine, at 33 months of age, is able to engage in some self-care behaviors but still has trouble with tasks such as putting on socks. A few months later, she accomplishes this same task relatively easily. The change in abilities is most likely due to _____.

Answer:

Developmental progression of functional skills

Explanation:

With the passage of time, a kid not only grows physically and mentally but also in his/ her cognitive abilities to perceive and understand the happening around him. He develops a a relationship sense for peers, family members and related adults. Similarly, he also develops the ability to learn the things which are quite basic for us like taking off clothing items.

These things come under the umbrella of developmental progression for functional skills.  studies have shown that a kid learns to take off clothing items before he learns to  put them on. Same is the case with putting on socks, a kid can take off socks by the age of 12 months which is earlier than he learns to put them off (age of 18 months) with the assistance of any elder and independently by the age of almost 4 years.

This developmental progression helps a kid to modify his behavior and to be more independent.

Hope it helps!

most animal cells membranes have proteins that pump Ions out of the cell and potassium ions into the cell

Answers

Ans.

The membrane proteins that pump sodium ions out of the cell from inside and potassium ions inside the cells are called as sodium-potassium pumps or sodium-potassium ATPases.

These proteins perform active transport by using energy from ATP hydrolysis and transport two potassium ions inside the cells, along with transport of three sodium ions outside the cells, against the concentration gradient.

Thus, the correct answer to complete the sentence is sodium.

What three things make up a nucleotide?

Answers

A nucleotide contains a base (adenine, thymine, guanine, or cytosine), sugar, and phosphoric acid.

What is a nucelotide?

Nucleotides are organic compounds that are composed of a base (one of the following four chemicals: adenine, thymine, guanine, and cytosine), in addition to a sugar molecule and a phosphoric acid molecule. They perform the function of monomeric units inside the nucleic acid polymers, which include ribonucleic acid and deoxyribonucleic acid. These two types of biomolecules are required for the survival of all kinds of life on Earth.

Nucleotides are required in order for metabolic processes and physiological functions to be carried out.
