How does a ring species illustrate speciation in action?

Biology
1 answer:
NikAS [45]3 years ago
3 0

Answer:

Speciation occurs at terminal population groups

Explanation:

A ring species represents a group of organism that has moved beyond a geographic barrier to produce a ring shaped distribution. This population is contiguous and there exists no barrier to gene flow anywhere in the ring except at the terminal populations.  

Speciation is demonstrated in the terminal population has become sympatric and it does not interbreed even if they are connected by chain of intergrading or interbreeding populations

Can someone help match these defenitions.
luda_lava [24]

The right matches are:

1. nuclear envelope  is matched with b.

2.centriole  is matched with  a.

3.interphase is matched with j.

4.furrowing  is matched with h.  

5.anaphase  is matched with g.

6.spindle apparatus is matched with f.

7.chromatin is matched with i.

8.haploid is matched with c.

9.meiosis is matched with e.  

10.homologous chromosomes is matched with d.


Cell division consists of the formation of two or more cells from a single cell, which ensures their numerical growth. During mitosis of a cell, each daughter cell is identical to the mother cell. During meiosis, the mother cell gives two haploid daughter cells with n chromosomes, then each of these daughter cells give two n chromatid cells.

May be some word in this exercise are not very common like:

The mitotic spindle, allows chromatid migration during cell division.

The dividing groove is the invagination of the cell surface that allows the cell to divide in two.

Centriole is a specific cell element of animal cells, which form the centrosomes located at both poles of the cell.

What is an alternative stable state? the first species to grow after a severe disturbance after a disturbance, a stable communit
Dima020 [189]

Answer:

In biomes the species community undergoes certain changes in evolution and growth in order to reach the climax.

Explanation:

  • An alternative stable state is one which suggests the discrete states are sperate by an ecological threshold and in opposition to the ecosystem that is changing and thereby stating that the ecosystem can exist in a variety of alternative state.  
  • The first species after origin grows develops and then declines. This community of species may be disturbed in middle such as by a fire or flood and forms the secondary community which is more diamine and resistant. The changes are known as seres in biomes.

ANTONII [103]

Answer:

The process that is used by producers to make glucose is called photosyntheis and the chemical process used by both producers ans consumers to make ATP ito contribute to the energy exchange is called cellular respiration.

Explanation:

Photosynthsis

Photosynthesis occue in the mesophyll tissue present in  leaves of plants .During photosynthesis the green plants or producers acquires CO2 from the atmosphere and utilizes water in presence of sunlight to produce glucose molecules along with the liberation of oxygen gas.

Cellular respiration

During cellular respiration the glucose molecules are oxidized to form energy in form of ATP along with the production of water and carbon dioxide.

    The O2 that formed during photosynthesis is inhaled by human beings for respiration whereas the CO2 that is produced as waste material inside our body is exhaled by us in the atmosphere.The CO2 is then used by the green plants to carry out photosynthesis.
