Answer:

C. experimental

Explanation:

Experimental variables are the variables that are changed during the experiments to observe the effects of these changes. An experiment usually has one or more experimental variables. An experimental variable that is changed to know its impact on some other variable is called the independent variable.

In the given experiment, goldfishes were exposed to various temperature conditions to observe the effect of temperature on respiration. Therefore, both temperature and respiration rate are the experimental variables here.

Why does compact bone have canaliculi, but spongy bone does not?
stich3 [128]
Canaliculi are tiny canals in bone between osteocytes containing osteocyte cell processes. A spongy bone, also known as a cancellous bone, is a bone with latticelike appearance. A compact bone is a bone that is denser and has fewer spaces than cancellous bone. A compact bone has canaliculi but the spongy bone doesn't, because compact bone tissues form the outer layer of the bone while the cancellous bone tissues form the inner layer of the bone and it does not have osteons. Anosteon is a single central canal, with its contents, and the associated lamellae and osteocytes surrounding it.

Normal development of the immune response is due in part to hormones produced by the _______
oksano4ka [1.4K]

The immune response is the body's defense mechanism against the pathogens. The immune response of the body protects it from bacteria, viruses and multiple other disease causing organisms. The normal development of this protective immune response of the body is produced by as a result of the hormones which are produced by the thymus gland. The thymus gland produces the T-lymphocytes, which are important for a healthy immune response. The thymus gland secretes thymosin which is crucial for the development of these cells.

Hence, the answer is 'thymus gland'.

What structure holds the two sister chromatids together as they prepare for cell division.
otez555 [7]

Two sister chromatids are held together by the centromere

<h3>The Chromosome</h3>

The chromosome consists of 2 sister chromatids that are linked together by a structure known as the centromere.

Each of the sister chromatids carries an allele of the same gene.

The link between the two sister chromatids is broken at the anaphase stage of the cell division when spindle fibers pull them apart towards opposite poles within the cell.
