Pseudopodia are temporary projections of the cell membrane of eukaryotic cells. And by temporary, it means that it is not a fixed structure. Single-celled organisms characterized by the ability to form arm-like protrusion that can be protracted or retracted are referred to as amoebae.
Answer:
D
Explanation:
This involves a dihybrid inheritance I.e. two genes are being passed on. During meiosis, specifically, the Prophase stage, homologous chromosomes (similar but non-identical chromosomes received from each parent) line side by side. According to the question, one chromosome contains A and B alleles and its homologue, received by the other parent carries a and b alleles. This means that the diploid individual has a genotype AaBb for that gene.
According to Mendel's law of independent assortment, the alleles separate independently of one another into gametes. I.e. allele A and a separates into the gametes without affecting alleles B and b of the other gene.
Crossing-over, which is the exchange of chromosomal segment occurs between the two homologues. Hence, the exchange of chromosomal segments containing alleles in the individual will possibly produce four gametes with the genotypes: AB, Ab, aB, ab.
Human chorionic gonadotropin is secreted from the placenta. The correct option is D.
<h3>What is HCG?</h3>
HCG is known as Human Chorionic Gonadotropin.
It is a hormone secreted by the placenta during pregnancy.
The hormone specifically functions to thicken the wall of the uterus in order to be able to support the growing embryo.
It also signals to the body system to halt the process of menstruation.
