If two parents who's blood types are both B produce a child that has blood type O, what can you say about the parent's genotypes?a. one is ii
b. one is IBi
c. both are IBi
d. nothing, this is impossible

Answers

Answer 1
Answer: Our blood groups are composed of two "letters", one from both parets.

People with Blood group B can have the type BB or B0 (IBi).

if they both have a blood group B0 (that is IBi) they can both give their children the "0" part of their blood group, and the child will have a 0 blood group.

The answer is

c. both are IBi (that is both are B0).
Answer 2
Answer: I believe the answer is C

What are the components needed in order for an experiment to be valid? Identify these components in the following experiment: A scientist is testing a new plant food to see if it causes plants to grow faster. The scientist tests two plants with the new plant food, and two plants he grows without plant food.

Answers

. Growing two plants without plant food at all doesn't count; in order to see if the new food is better, he must also grow plants with the original food in order to compare it. 
  have an independent variable. This is the type of plant food. It's independent because he has direct control over it.give plants the same conditions besides food: same water (amount), same light exposure, same temperature, etc.

In which part of the nephron are sodium and chloride ions actively reabsorbed?A.
Glomerulus

B. Loop of Henle

C. Bowman's capsule

Answers

Answer:

The correct answer is option C. loop of Henle.

Explanation:

The loop of Henle is the part of a nephron in the kidney, that starts from the proximal convoluted tubule or PCT to the distal convoluted tubule DCT. The major role of the loop of Henle is to build a concentration gradient in the kidney.

Sodium (Na+), chloride (Cl−) and potassium (K+) ions are reabsorbed by secondary active transport from the urine by a Na-K-Cl co-transporter. The electrical gradient and concentration gradient causes more reabsorption of calcium (Ca2+), magnesium (Mg2+) and Na+.

Thus, the correct answer is option C.
Hey there! Here is my answer.

B. Loop Henle

Reason: Well, let's keep it short and sweet, it ascends, also meaning to rise, go up, or increase in size!

which organism would more closely resemble it's parent,one produced by asexual reproduction,or one produced by sexual reproduction? why?

Answers

An organism produced by asexual reproduction would more closely resemble its parent because an organism produced through asexual reproduction is created by the parent duplicating its genetic code and separating into two. Essentially the child is a duplicate.
Asexual, because the offspring comes directly from its parent organism
