Answer:
64
Explanation:
Since the cell has two chromosomes and a diploid number of 2, in each generation, the cell doubles. In the first generation, we have two cells, in the second generation, we have 2 × 2 cells ,in the third generation, we have 2 × 2 × 2 cells. It follows that we have 2ⁿ cells in each generation where n represents the generation.
So, in the fifth generation, n = 5, so the number of cells is 2⁵ = 32.
Since we have 2 chromosomes in each cell, the number of chromosomes in the 32 cells in the 5th generation is 2 × 32 = 64 chromosomes.
Answer:
b. muscle
Explanation:
The Sponges usually known as Porifera (pore bearers) are aquatic filter feeders. The sponges consist of structural materials (spongin, spicules) which are usually made of calcium carbonate and/or silica. These structures forms their skeletal materials giving their body a thin sheet of cells over a frame (skeleton). As invetebrate and at the unicellular level of organization, Sponges lack muscle.
Because caffeine is a big polar molecule and it can't pass directly through the phospholypid bilayer so it needs to pass through a channel.
Answer:
With a single species, competition is more intense because the one specie because if the one prey they hunt is scarce, then the whole specie has a chance of dying out quicker. With two different species, they have a wider variety of prey they can hunt, who knows, the two species may hold a separate niche which can help them surpass the competition. With a singular specie with the same niche having competition, then they're niche has a greater chance of dying out. Even if one animal's niche collapses entirely, this could lead to a whole ecosystem collapsing--Considering the fact that each animal's niche is equally important to the ecosystem.
