Sponges have no trust tissues. what does this mean ?

Biology
1 answer:
Nesterboy [21]3 years ago
5 0
Sponges have cellular-level organization, meaning that that their cells are specialized so that different cells perform different functions, but similar cells are not organized into tissues and bodies are a sort of loose aggregation of different kinds of cells. This is the simplest kind of cellular organization found among parazoans

Explain (1) what type of variation is always required for natural selection and (2) where this variation comes from?
larisa86 [58]

When we talk about evolution we come across the process of natural selection. Genetic variation is always required for the natural selection. A change or variation in the genes may help the individuals in a population to better adapt to the environment. Such changes may be brought by mutations or random mating in the population. Such variations help in the survival of the population by allowing them to adapt to changing environmental conditions.

Free palmitate is activated to its coenzyme A derivative (palmitoyl-CoA) in the cytosol before it can be oxidized in the mitocho
Andrew [12]

Answer:

The cytosolic and mitochondrial pools of CoA are  kept separate, and no radioactive CoA from the cytosolic pool enters the mitochondrion.

Explanation:

  • Fatty acyl group condensed with CoA in the cytosol are first transferred to carnitine and in this process, CoA is released.
  • After this, it is transported into the mitochondrion, where it is again condensed with CoA.
  • In this way, the cytosolic and mitochondrial pools of CoA are kept separate, and due to this reason, no radioactive CoA from the cytosolic pool enters the mitochondrion.
  • Therefore, according to the given question, the C14 CoA that is added into the liver homogenate along with palmitate shows cytosolic radioactive fraction but not mitochondrial as in the mitochondria a different CoA joins palmitate and not the one containing C14.
