The position of the Earth in the solar system and more regional effects, such as carbon dioxide levels, all play a role in the causes of ice ages. Thus, option A is correct.

<h3>What are factor that involve in ice age on earth?</h3>

When the orbital cycle turns back, these feedbacks—involving the spread of ice and the emission of greenhouse gases—work in reverse to warm the Earth once more.

A prolonged period of cooling of the Earth's surface and atmosphere is known as an ice age, which is marked by the development or presence of polar and continental ice sheets as well as alpine glaciers.

Flooding has increased along the U.S. coastline as a result of the warming, rising, and acidifying of the seas.

Therefore, The Earth is currently facing an ice age.

In mice, the allele for black fur is dominant to the allele for brown fur. a male homozygous black mouse is crossed with a femal

Darina [25.2K]

B- black allele;
b- brown allele;

The parental cross is true-breeding because both the male and the female are homo zygotes, so: BBx bb

The F1 generation will be all black heterozygote: Bb
The F2 generation will be between mice of the F1 generation and they all have the same genotype:Bb xBb
In this cross it would result in:
1/4 of the plants being black homozygote-BB 25%
2/4 of the plants being black heterozygote- Bb- 50%
1/4 of the plants being brown homozygote- bb- 25%
answer: 25%+25%=50% are homozygotes

Graphic Organizer: Cell Membrane

Simora [160]

The cell membrane maintains homoeostasis in the body which is the process by which cell maintains a fairly constant environment.

<h3>What is the cell membrane?</h3>

The cell membrane is a lipid bilayer membrane which separates the contents of a cell from the external environment.

The correct graphical chart is as follows:

cell membrane maintains homeostasis
active transport requires energy
passive transport does not require energy
Diffusion occurs either through osmosis or facilitated diffusion
facilitated diffusion occurs through protein channels
Osmosis involves movement of water
Endocytosis is the process the cell takes in substances into its inner compartment
Exocytosis is the process the cell takes in substances into its inner compartment
Pinocytosis is cell drinking
Phagocytosis is cell eating

Therefore, the process by which cell maintains a fairly constant environment is called homoeostasis and is maintained by the cell membrane.

An objects position is always defined relative to a reference point. If the object changes position, its motion can be described

Orlov [11]

The position of the diver is described as "below a certain point"; therefore, the reference point must be above the diver. For a diver in the middle of his dive, the bottom of the pool, the other swimmers and the far side of the swimming pool are likely to be below the diver, or at level with the diver at most. Out of the options, the only point of reference that is likely to be above the diver is B. the diving board.
