Answer:
Gamete C
Explanation:
During the formation of gametes, the DNA is first duplicated, and 2 separate cell divisions take place to make a haploid cell.
In the first division, the homologous chromosomes are separated
Before the first cell division, the homologous chromosomes align in the centre. In this cell, the light green and dark green chromosomes align, as do the light purple and dark purple chromosomes. These are then separated into 2 different cells, 1 gets either the light or dark green chromosome and either the light purple and dark purple chromosome. The other cell also gets either light green or dark green and light purple or dark purple.
Then, a second division takes place that separates the sister chromatids to produce what we see in the gametes A, B, C, and D.
The only one that is not possible in a healthy cell is C, because it has not received any of the green chromosomes and instead has two homologous purples.
Answer:
The correct answer is - 1. true, 2. true, 3. false, and 4. true.
Explanation:
1. Rod cells are the photoreceptors present in the retina that are hyperpolarized not depolarized in dark due to sodium ions efflux.
2. Depolarisation of the bipolar cell of the retina by glutamate release by rods and cones.
3. The adaption according to the light is known as a light adaptation which takes place due to a large part of photochemical in both rods and cones which is reduced to retinal and opsins.
4. when the light reaction takes place retinal converted to opsin
Answer:
The plasma membrane forms a barrier which is phospholipid bilayer on the outer and inner surface and compartments on the inferior
The following option are correct:
1. There will be interspecific competition between foxes and tigers.
Competition for food between animals of different species is called interspecific competition while that between the same animal species is called intraspecific competition.
2. The energy received at the tropic level of carnivores will be less than the usual amount.
The energy received at the trophic level become reduced because the amount of food available for the carnivores has been reduced.
3. There will be decreased biomass at the trophic level of carnivores.
Decrease biomass will occur at the trophic level of carnivores because, those carnivores that can not survive the food reduction problem will die off.
Answer:
oxygen will diffuse into the body tissue cell
Explanation:
diffusion is the movement of particles from a region of higher concentration to a region of lower concentration.
since oxygen in the blood surrounding the cell is higher, oxygen will diffuse from the into the body tissue cell which is lower.
