<span>Animals gradually adapt to changes within their environment over time. This gives them a better chance of surviving rather than going extinct because of the change. Say there is a gene mutation affecting color within a population of beetles in a rain-forest. All of the beetles used to be red, but now a few of them have experienced a gene mutation and are green. Because they live in a rain-forest, it is likely that the green beetles would blend in with their surroundings far better than the original red beetles, and those red beetles would be wiped out by predators because they are easier to spot. The green beetles would live on and flourish, and their population would increase. Soon there would be few or none red beetles, and many green beetles.</span>
Depending upon the type of energy detected by receptors , they can classified into many groups but you need for so I'm going to write here only four with their functions
1. Thermoreceptors: they detect changes in temperature
2. Chemoreceptors: they detect chemicals dissolved in body fluid medium surrounding them.
3. Mechanoreceptors: they detect sound , motion , position in relation to gravity.
4. Photoreceptors: they detect visible and ultra violet light!
Hope so it would help!
Answer:
A cell that has duplicated chromosome cannot be in<u> G1 phase.</u>
Explanation:
- G1, G2 and S phase are the divisions of the interphase i.e. the resting phase of the cell cycle.
- A cell cycle has two phases; interphase and M-phase.
- During interphase the cell grows and in M-phase it divides.
- G1 is the Gap between the M-phase and the S-phase.
- G2 is the gap between the S phase and M phase.
- DNA replication is confined to the S part of interphase.
- Since G1 phase comes before the S phase , we can say that a cell that has duplicated chromosome cannot be in G1 phase.
The fluid is called blood
The first statement matces with the last option - autosome
The second one goes with chromosome theory
Then, third is diploid
The next - haploid
Sixth - <span>linkage
Then </span>x chromosome and y <span>chromosome
Hope you still need the answer because this one is really helpful.
