Answer;
-23 in males
In humans, 23 in males is the only homologous chromosome pair that isn't the same.
Explanation;
-In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46.
-Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females. Females have two copies of the X chromosome, while males have one X and one Y chromosome.
-The 22 autosomes are numbered by size. The other two chromosomes, X and Y, are the sex chromosomes.
Answer:
active transport, like Na + ions leaving the cell
Explanation:
The active transport requires an energy expenditure to transport the molecule from one side of the membrane to the other, but the active transport is the only one that can transport molecules against a concentration gradient, just as the diffusion facilitated the active transport is limited by the number of transport proteins present.
Two major categories of active, primary and secondary transport are of interest. The primary active transport uses energy (generally obtained from ATP hydrolysis), at the level of the same membrane protein producing a conformational change that results in the transport of a molecule through the protein.
The best known example is the Na + / K + pump. The Na + / K + pump performs a countertransport ("antyport") transports K + into the cell and Na + outside it, at the same time, spending on the ATP process.
The secondary active transport uses energy to establish a gradient across the cell membrane, and then uses that gradient to transport a molecule of interest against its concentration gradient.
The answer is A. cleavage, differentiation, fertilization, gastralution
Answer:
<em>Beans and whey protein.</em>
Explanation:
The most abundant element in the atmosphere is nitrogen, and both beans and whey protein contain nitrogen.
Hope this helps! :)
