Answer:
During metaphase, all of the chromosomes are aligned in a plane called the metaphase plate, or the equatorial plane, midway between the two poles of the cell. The sister chromatids are still tightly attached to each other.

Your answer is B, C , and D.
Answer and Explanation:
Mutation:
It is the sudden variation that occurs in the sequence of our DNA either due to factors related to environment or mistakenly. These are inheritable changes in our genes.
Effects:
a. It results in the ability of an organism to adapt to the environmental variations.
b. It can also cause disorders and diseases in an organism.
c. It results in the evolution of organisms.
d. It also results in the variation in an organisms' phenotype.
d. It helps to carry out scientific research.
Patterns of Inheritance:
The inheritance in mutation only occurs when it is in germ cells which leads to the production of gametes and this mutation is known as germ line mutation.
Data analysis:
As only few cells are effected mostly in mutation it can not be detected.
Answer:
Properties of life include the use of <u><em>energy</em></u> to power an organisms activities.
Explanation:
Energy is the driving force which allows every cell to perform its functions. Organisms like humans tend to gain energy by the process of cellular respiration. Cellular respiration can be described as a process in which organisms make carbon dioxide and water from glucose (from food) and oxygen (from air). Huge amounts of ATP is also released during this process. In plants, the process of photosynthesis and cellular respiration supplies them with the energy sources.
The introduction of the Asian Clam in Lake George is an example of an Invasive Species.
Asian Clam are small in size, hardly 1.5 inches long. However, they can reproduce very quickly without the need for a partner. A single clam can give birth to hundreds of offspring in a single day without a mate.
Asian Clam is extremely unpleasant for most fresh water bodies since it excretes nutrients such as nitrogen.
This helps in the development of algae and gives off a foul stink.
