I'm not sure but if you are talking about cells I think it is cytoplasm.
Answer:
Duplication of hox genes is important in the radiation of animals because they are regulating genes of symmetry and the body plan of the animals' bodies. Some change or mutation in these genes during duplication can cause mutations and with these evolution of the species as it controls the different segments of these animals as they develop, launching the genetic programs that form various body structures, such as limbs and organs. .
Answer:
The correct answers to the question are:
- The concentration of solute bathing the inner side of the plant cell membrane should be high.
- The concentration of solute bathing the outer side of the plant cell membrane should be low.
Explanation:
- Turgidity can be defined as a condition in which the cell membrane of the plants cells becomes completely extended as a result of which it pushes tightly against the cell wall.
- This happens when the cell takes up water from its environment and stores it in the vacuoles.
- Water enters to the inside of the cell by the process of Osmosis.
- Osmosis can be defined as the process by which molecules tend to move or diffuse from a region where its concentration is high to another region where its concentration is low, provided the two regions are separated by a semi-permeable membrane.
- In any region, the concentration of solute and and concentration of solvent bears an inverse relationship. This means that the region where the solute concentration is high, the solvent concentration is low and where the solute concentration is low, the solvent concentration is high.
- In the given question, as the cell takes up water from the surrounding into its vacuole to become turgid, so by the concept of osmosis, the concentration of water must have been high outside the cell and low inside the cell.
- Again by the inverse concentration concept of solute and solvent, the concentration of solute inside the cell should be more than the concentration of solute outside the cell.
According to the theory proposed by Harry Hess, what causes continents to move?
The correct answer is : seafloor spreading.
Earlier, in 1912 Alfred Wegener produced evidence that the continents are in motion but this idea was shelved as he could not explain what forces the continents to move. So, almost 50 years later Harry Hess confirmed Wegener's ideas by using the evidence of seafloor spreading to explain what moved continents.
I believe it is D bcuz there is no more reproducing of that species so it will eventually die out.
