Cells at the completion of meiosis compare with cells that are in prophase of meiosis I is (A) The cells have half the number of chromosomes and half the amount of DNA.  

The correct option is (A).

  • The cells produced at the end of meosis cell division have half the number of chromosomes (termed as Haploid), so they will have half the number of chromosomes but same DNA as that of the parent cell as DNA divides and makes a copy of the parent cell DNA.
  • Meiosis is a form of cell division of germ cells that creates gametes such as sperm or egg cells in sexually reproducing animals. It consists of two rounds of division that result in four cells with just one copy of each chromosome (haploid). Prior to division, genetic material from the paternal and maternal copies of each chromosome is crossed across, resulting in novel code combinations on each chromosome.
  • During fertilisation, the haploid cells generated by meiosis from a male and female will unite to form a zygote, a cell with two copies of each chromosome.

Temperature in the tropics all year, whereas temperature at higher latitudes. Organisms that are physiologically adapted to cons
Reptile [31]

Answer:

May not

Explanation:

Adaptation is made possible as a result of an organism being exposed to different environmental conditions. These exposure makes it adopt different techniques for its survival which eventually results in it being adapted to the condition and is then passed on as traits to its offsprings. They are then able to survive when met with such environmental condition.

When an organism is exposed to the same conditions all the time then there is lack of genetic variation and adaptation may not occur.

What would happen to the possible variation in gametes if the number if chromosome pairs increased from two to three?
Orlov [11]
<span>If each of the pairs of chromosomes was heterozygous (what gives you the highest potential number of different gametes), then the number of possible gametes increases from 4 to 8 for a diploid organism. To figure out how many are possible, raise the number of homologous chromsomes (2 for a diploid organism) to the power of the number of chromosomes. So if you have two different chromosomes (A and B), raise 2 to the 2nd power (or multiply 2 x 2) and you have 4. If you have chromosomes A, B, and C, then you have 2^3, or 2 x 2 x 2 = 8.

To show possible combinations, AaBb gives you AB, Ab, aB, or ab. AaBbCc gives possible gametes of ABC, ABc, AbC, Abc, aBC, aBc, abC, and abc. </span>

Group the following into the appropriate range of measurement.
Vesna [10]

Answer:

Hydrogen atom & glucose molecule --- atomic.

Herpesvirus, DNA --- ultramicroscopic.

Protozoan, Rickettsia - microscopic.

Roundworm and algae --- macroscopic

Explanation:

1) Hydrogen atom & glucose molecule --- atomic.

The atomic size level, which interacts with atoms as well as small molecules, is much lower than the ultramicroscopic range.

2) Herpesvirus, DNA --- ultramicroscopic.

Ultramicroscopic particles are very tiny structures that cannot be seen using a conventional optical microscope, necessitating the use of an electron microscope. Viruses and DNA falls into this group since they are much smaller than tiny species like bacteria.

3) Protozoan, Rickettsia - microscopic.

Microscopic species are much smaller than macroscopic organisms because they cannot be observed by the naked human eye and must be viewed through a microscope. The size range for microscopic particles is ( 10^3  \ \ to  \ \ 10^{10}), which contains protozoans and Rickettsia (a gram-negative, non-motile bacteria genus).

4) Roundworm and algae --- macroscopic

Naked eyes can see macroscopic organisms; for example, several types of circular worms and algae can be seen by them.

How do the parts of the flower interact as a system for the purpose of reproduction?​
lesya [120]

Answer:

The function of the male parts of flowering plants is to produce pollen grains. The pollen grains contain sperm which will fertilize the egg and create a seed to sprout the next generation of plants. The main male part is the stamen. It is divided into two parts: the anther and the filament.

Explanation: that may or may not help, but i hope it does
