I think it is C An increase in the activity of nitrogen-fixing bacteria but don’t hold me to that I’m not sure
Answer:
choanoflagellates and sponges are sister groups
Explanation:
The choanoflagellates are small unicellular organisms belonging to the Protista kingdom. These microorganisms are collared flagellates morphologically similar to the choanocyte cells of animal sponges, which have a central flagellum surrounded by a collar of microvilli. In consequence, it has been suggested that choanoflagellates may represent the closest living relatives of primitive metazoans (i.e., they are sister groups to sponges). This hypothesis has recently been supported by both molecular phylogenetic and comparative genomic analyses.
The answer is aneuploidy.
This means having an abnormal number of chromosomes
in a cell. MAD protein ensures that the spindle fibers
during metaphase of mitosis, attach properly.
The MAD protein inhibits progression to anaphase if this
process of spindle attachment is defective.
Answer:
The correct answer is - no it cant not change from the lytic cycle to the lysogenic cycle.
Explanation:
In the lysogenic cycle, phage DNA is fused into the host genome, where it is moved to the next generation with the host genome. Natural stressors, for example, exposure to toxic compounds or starvation may cause the prophage to extract and enter the lytic cycle where the virus burst or kill the host genome.
So, in the lytic cycle virus kills the host cell s there is no chance or need to change into the lysogenic cycle as whereas in the lysogenic cycle virus incorporated with the host and becomes a chromosome.
Answer:
1. Cell walls: virtually all bacteria contain peptidoglycan in their cell walls; however, archaea and eukaryotes lack peptidoglycan. Various types of cell walls exist in the archaea. Therefore, the absence or presence of peptidoglycan is a distinguishing feature between the archaea and bacteria
