A man with blood type B marries a woman with blood type A . Their first child has blood type 0 . Use a Punnett square to predict what other blood types are possible for their offspring .

Answers

Answer 1

Answer:

Answer:

They have 1:4 chances of 0, 1:4 cahnces of AB, 1:4 chances of A, 1:4 chances of B

Explanation:

Blood has three types of alleles: A, B, 0 depending on the type of proteins in blood cells. They can have protein A, B, or not having them 0. The dominant allele will be B or A.

All types of blood are A, B, AB (co-dominance) and 0.

We all have two alleles for each gene, one comes from our mother, and one comes from our father.

If both parents are dominant, but they have a recessive child, you have both heterozygote genes to do the Punnett square.

Mother: I(A)i(0)

Father: I(B)i(0)

Answer 2

Answer: The punnett square is attached to this.
The other possibilities are AB, BO, and AO.
All of them have 25%.

An example of multiple allelism in humans is?

Answers

Answer The correct answer is -

An example of multiple allelism in humans is ABO blood group system.

Explanation:

Multiple allelism can be described as a condition when three or more than three gene variant ( also called alleles) occupying the same locus, are present within a population. However, only two of those alleles are present within a single organism.

For example, the ABO blood group system, which is controlled by three different alleles (A, B, and O) is an example of multiple allelism.

Two human examples of multiple-allele genes are the gene of the ABO blood group system, and the human-leukocyte-associated antigen (HLA) genes.

How does atp become adp

Answers

If a cell needs to spend energy to accomplish a task, the ATP molecule splits off one of its three phosphates, becoming ADP (Adenosine di-phosphate) + phosphate. The energy holding that phosphate molecule is now released and available to do work for the cell.

What is the chemical equation for cellular respiration?

Answers

Correct answer is:

$C_(6)H_(12)O_6+6O_(2)\Rightarrow 6CO_(2)+6H_(2)O+energy$

But how to get there?

Let's start with simple explanation of what exactly is cellular respiration.

Cellular respiration is a multistage biochemical oxidation process of organic substances when prime product is energy (ATP - adenosine triphosphate) and other are released waste products.

Cellular respiration takes place even if other metabolic processes are stopped, but cellular respiration may differ in particular organism groups.

Some reactions during whole process of cellular respiration are similar in all types of living organisms.

Cellular respiration is prime indication of declining living processes.

Only viruses which are on the edge of living organism and chemical particle are not performing cellular respiration.

But to the point :P

In cellular respiration all substrates which are in the cell might be organic, but mostly we are using sugar oxidation - glucose in the presence of oxygen.

Chemical formula of sugar looks like this:

$C_(6)H_(12)O_6$

Oxygen is just $O_2$

so for now we have just part of the equation:

$C_(6)H_(12)O_6+O_(2)\Rightarrow$

But what would be on the right hand side?

It's quite simple, remember equation of full combustion? If we want to burn something we need oxygen like in the equation, so the product of this equation would be carbon dioxide, water and of course energy (ATP).

Carbon dioxide formula looks like this:

$CO_(2)$

As a reminder water formula:

$H_(2)O$

Full formula would look like that:

$C_(6)H_(12)O_6+O_(2)\Rightarrow\ CO_(2)+H_(2)O+energy$

But still as you see this equation is unbalanced, after balancing it would like that:

$C_(6)H_(12)O_6+6O_(2)\Rightarrow 6CO_(2)+6H_(2)O+energy$

At the end I would like to explain one more thing. Energy which has been released during this process is part of high-energy connection which might be used to perform chemical reactions in the cell or to move organism for example in muscles. We need to remember that production of ATP is not happening with 100% efficiency and part of this energy is released as heat.

$C_(6) H_(12) O_(6) +6O_(2) ---\ \textgreater \ 6CO_(2) +6H_(2) O+ENRGY$
