<h3><u>Answer;</u></h3>
B.introduced species
<h3><u>Explanation;</u></h3>
- <em><u>Animals become extinct for a number of reasons. Currently many animals are endangered or have become extinct due to human activities or human influence.</u></em>
- Extinctions may be caused by reasons;<em><u> such as pollution; loss of habitat due to human activities such as agriculture, introduced species, hunting and poaching for meat and other animal products such as feathers, horns and skins, and also over-harvesting among other influences.</u></em>
- In this question; <em><u>Introduced species occupies the largest percentage, that is 39%, from the pie chart (Attached).</u></em>
- Hunting and poaching; 23 %, Habitat loss; 26%, and Others; 2%.
Answer:
Speciation was allopatric or peripatric, but would depend on the number of individuals that dispersed from the original populations.
Explanation:
- There are two types of speciation: allopatric and peripatric.
- Allopatric speciation occurs when the species of same population gets isolated that results in lack of gene flow.
- From the isolated population, new species are formed then it is known as the peripatric speciation.
- All these isolation of populations and formation of new species depends upon the initial or original group of species that was dispersed.
In the plant, when a cell divides into two daughter cells, we observe in this experiment Mitosis, which is the cell division that allows the plant to elongate and occurs in the meristematic tissues that are at the ends of the plants. Whereas meiosis is restricted to reproductive tissue and forms gametes that will form new seeds through fertilization, carrying genes from one generation to another.
<h3>How does mitosis occur in plant cells?</h3>
In plant cells, division takes place from the inside out – centripetal cytokinesis. In plant cells, cytokinesis is centrifugal, from the outside to the inside: there is the formation of a lamella, which grows from the center to the periphery and separates the two cells.
With this information, we can conclude that through successive mitotic divisions that the zygote (cell generated after the meeting of gametes) manages to originate all the cells of its organism. Mitosis, therefore, is responsible for the growth and development of embryos.
