Catalyst. A catalyst is a substance that increases the rate of a reaction without being consumed the rate of a reaction without being consumed in process, or being chemically altered. There are many enzymes present in cells, proteases, lipases, that speed up metabolism, and catalysts .

Compare the amount of hyaline cartilage found in an embryonic skeleton compared to a child
larisa [96]
The amount of hyaline cartilage in the embryonic skeleton is much higher than in a child. This is because the embryonic skeleton will still go calcification as the embryo ages to fetus and eventually to being a child to adulthood.

Describe the path blood takes through the circulatory
ratelena [41]
Ooh this will be good

So blood let’s say starts in the left atrium where it goes down through the mitral valve into the left ventricle. From the left ventricle of the blood is pushed through the aorta and from there through the various branches of the body eventually allowing oxygen rich blood to flow all across the body. Once this blood is picked up by veins as deoxygenated blood it goes back to the heart through the inferior and superior vena cava. From there the deoxygenated blood is sent into the right atrium, through the tricuspid vale into the right ventricle, through the pulmonic valve into the pulmonary artery and into the lungs for re-oxygenation. The re-oxygenated blood (oxygen rich blood) now goes through the pulmonary veins into the left atrium and the cycle beings again.


Remember this, Left side of heart is for oxygenated blood, Right side of heart is for deoxygenated blood.

Artery takes oxygen rich blood away from heart itself
Vein takes oxygen poor blood back into the heart

Exceptions, Pulmonary Artery takes oxygen poor blood away from heart and into lungs

Pulmonary vein takes oxygen rich blood into the left atrium to be pushed to the rest of e body.

timofeeve [1]

In order to test the implications of early emotional bonding, scientists have done testing on infant emotionality by separating animal babies from their natural mothers, allowing them to be raised by another of their same species. This testing strategy is called Cross fostering

  • Transfer of children between mothers is known as cross-fostering. This method is used to distinguish between environmental and genetic impacts on behavior.
  • Transferring some freshly born or hatched young of species A from their mother nest to the nests of species B is the primary process of cross-fostering.
  • A behavior can be proven to have a genetic foundation if cross-fostered offspring have a behavioral attribute that is distinct from that of their foster parents and similar to that of their biological parents.
  • Similarly, environmental variables are proven to be dominating if the offspring exhibits qualities that are different from those of their biological parents and comparable to those of their foster parents.
  • There is frequently a combination of the two, demonstrating both genes.
  • This can be utilized in selective livestock breeding to combine desirable genetic traits like weight, fat distribution, or looks with ones that are influenced by the environment, like temper.

In humans, the hormone testosterone enters cells and binds to specific proteins, which in turn bind to specific sites on the cel
LuckyWell [14K]

Answer:

As a transcription factor

Explanation:

Testosterone is a male sex hormone secreted by the testicles which promote the growth of the male reproductive organs and the male characters like muscle buildup.

The hormone shows the paracrine effect and thus act on the target cell at distant. The mechanism of action of the testosterone is that it controls the gene expression of various other genes.

The testosterone binds the specific proteins which activate the expression of the gene that is they acts as a transcription factor which activates the expression.  

Thus, as a transcription factor is correct.
