Answer:
As the graph is not provided, lets try to answer the question generally.
Explanation:
Human activities are known to be threatful and harm biodiversity in several ways.
Humans activities like deforestation results in many species from losing their homes. These species are not able to survive and hence become extinct.
Human activities such as fragmentation cause the genetic diversity to become lowered for organisms of a species. As a result, a disaster such as a disease results in killing all the organisms of a species present in a community.
Answer:
The correct answer will be-
1. Mitosis
2. Meiosis
3. Mitosis
4. Meiosis
5. Meiosis
6. Meiosis
Explanation:
A cell can divide by one of the two ways of cell division which are: Mitosis and Meiosis.
During mitosis, a cell undergoes four stages of distribution of nuclear material which are prophase, metaphase, anaphase, and telophase and easily characterised.
The mitosis division produces cells with the same genetic material called clones and is involved in the division of the somatic cells. This helps in the growth and repair of the damaged tissue.
Meiosis type of cell division divides and form the four haploid cells from parental cells. The process produces haploid cells in two stages: Meiosis I and Meiosis II. The tetrad formation takes place during the prophase I of the meiosis I.
BMR or Basal Metabolic Rate
Answer:
A.The hole in the ozone layer
Explanation:
• Montreal protocol is an international treaty that was signed to control the use of substances that are resulting in the depletion of the ozone hole.
This treaty was signed in the year 1987 and became effective form 1989.
• Since the time that this treaty has come into force, there has been a significant improvement in the ozone hole that was observed over Antarctic as it's size has decreased.
• This improvement has been possible because the treaty helped to phase out chemicals such as chlorofluorocarbons, carbon tetrachloride, etc. that are responsible for ozone hole depletion.
