The answer is letter D. The macronucleus is not exchanged during conjugation. <span>It normally contains the working duplicates/copies of genes necessary to support an enormous cell. Macronucleus is formed by a direct division of the polyploid nucleus right after conjugation then followed by series of internal gene replication that is not oftenly occurring in micronucleuse.</span>
the brain is the only place you wil find brain nurons and when a person is in a coma the brain is not running at a fast alert as it would if u where awake the brain is working at a really slow alert speed becuase u wont be able to jus shake and wake a person out of a coma becuase the brains nurons are working slow
Answer:
47
Explanation:
We all know that gametes like egg cell and sperm have haploid set of chromosomes but here as per this question she has produced 2 copies of chromosome 21. For the sake of maintaining haploidy, she was supposed to have only a single copy of chromosome 21 as a result of which her egg cell was supposed to have 23 chromosomes not 24.
But, this is a case of non dis-junction. Also, in a normal sperm there are no such copies of any chromosome i.e. there is a haploid set of chromosomes. It means that sperm must be having only 23 chromosomes. So we can easily infer that when the egg cell and sperm will fuse, the zygote will have 47 chromosomes (24 from egg cell and 23 from sperm).
Answer:
Animal Respiration Every cell in an animal requires oxygen to perform cellular respiration. Cellular respiration is the process by which animals take in oxygen and exchange it for carbon dioxide and water as waste products.
