The fertilized egg cell of a mouse contains 40 chromosomes
Answer and Explanation:
Cells are made of DNA (Deoxyribonucleic Acid).
They provide the genetic instructions for making and forming a cell.
The DNA is found inside the nucleus of the cell.
Because the cell is very small, and because organisms have many DNA molecules per cell, each DNA molecule must be tightly packaged. This packaged form of the DNA is called a chromosome
DNA do NOT have cells, but cells DO have DNA.

Smooth muscles depolarize as a result of a transmembrane current of Calcium ions. When an action potential depolarizes the muscle cell membrane, it also travels into the body of the cell via the t-tubules. Unlike skeletal muscle, smooth muscle is dependent in two sources of calcium in order to intiate contraction. These two sources are calcium sequestered in the S.R. of the smooth muscle cell.
Herbivore; carnivore
A rabbit is an example of a herbivore while a hyena is an example of a carnivore.
A herbivore is an animal that obtain its energy by feeding mainly on plants (i.e. that eats no meat). Other examples of herbivores apart from rabbit are cows, sheep and insects. A carnivore is an animal that feeds on meat as the main parts of its diet. Other examples of carnivores apart from hyena are lions, coyotes, tigers and eagles.
Global warming is a phenomenon of rising the average temperature of the earth over the past 100 years.
The following would provide the best evidence to support the claim :
(A) Habitat loss would occur, leading to a decline in species diversity.
<h3>Global warming has a long term impact on the ecosystem</h3><h3 />
- The earth warming gases are carbon dioxide, methane, nitrous oxide, etc.
- As the earth will warm up, we will experience more extreme weather, heatwaves, and droughts.
- Due to heat, the glaciers are melting to a high extent.
- Due to the melting of the glaciers, the sea level is rising.
- Some animals are already experiencing extinction due to global warming.
- Due to the loss of habitat, there is a loss of diversity.
Thus, the correct option is: (A) Habitat loss would occur, leading to a decline in species diversity.
