Chromosomes are visible under the microscope during cell division, as because the chromatin has condensed and essentially the DNA with numerous histone proteins wrapped around and folded again and again to produce thick structures of chromosomes during prophase.

A population's emigration in one month totaled three individuals. During the same period, immigration was 17 individuals. Natali
Ratling [72]

There was no net change in the given population. The size of the given population remains unchanged.

The explanation behind this is that if we consider the given values-

Emigration- 3

Immigration- 17

Natality- 12

Mortality-26

Therefore,

The overall effect on the population will be=

(Emigration+ Mortality) - (Immigration + Natality)

= (3+26) - (17 + 12)

=29-29

=0

Here the emigration means the number of people who have migrated from the population. Mortality refers to the number of deaths in a given population. Immigration is the migration of people into the population and natality is the overall number of births that have taken place in a population. Therefore there is no net gain or loss in the given population. This exerts no effect on the population keeping it unchanged.

If you place an organism classified as a photoautotroph at the bottom of a lake and later see that it is able to acquire nutrien
kkurt [141]

Answer:

The correct answer is- photoheterotroph

Explanation:

Photoheterotrops are the organisms that get their energy from sunlight but they take their nutrient or carbon source from the organic compounds like from other plants and animals. Carbon dioxide is not used by them as their source of energy.

Some of the examples of photoheterotroph are purple non-sulfur bacteria, green non-sulfur bacteria, etc. Therefore here the organism which was thought to be photoautotrophs acquire nutrients from dead plants material therefore they are actually photoheterotrophs.
