<h3>Answer;</h3>

Ground cover vegetation

Permafrost remains throughout the summer because it is insulated by ground cover vegetation.

<h3>Explanation;</h3>

Permafrost is permanently frozen soil, a common feature of Polar regions. There is a layer at the surface of varying depth which does melt during the summer when the temperature consistently warms above freezing.
Permafrost is often rich in organic matter due to the slow rate at which it decomposes in these climates.Permafrost remains throughout the summer because it is insulated by ground cover vegetation.

Which of the following is TRUE of a cell membranes?

adoni [48]

Answer:

B, C, Dand E are all correct

Explanation:

Why B is correct- The cell membrane, also known as the plasma membrane, is a double layer of lipids and proteins that surrounds a cell and separates the cytoplasm (the contents of the cell) from its surrounding environment. It is selectively permeable, which means that it only lets certain molecules enter and exit.

Plants, animals, and bacteria have a cell membrane. Why d is correcect

Why C is correct- The cell membrane is not a solid structure. It is made of millions of smaller molecules that create a flexible and porous container. Proteins and phospholipids make up most of the membrane structure.

Why E is correct- The plasma membrane is primarily composed of phospholipids arranged in a bilayer, with the hydrophobic tails on the interior of the membrane, and the hydrophilic heads pointing outwards

Why A Is Not correct- It is very fragile and its role is to hold the cell together and to help control what substances can get in and out. It is partially permeable, allowing only some substances to pass through it. The membrane has a complex structure consisting of a phospholipid bi-layer and different types of proteins.

In cats, being awesome (A) is dominant to being average (a), and being bashful (B) is dominant to being

BlackZzzverrR [31]

Answer:

Probability that both cats described will have an offspring who is heterozygous for both traits is 50%, according to the scenario given.

Explanation:

When a cat amazing and bashful is crossed with a cat average and boring, it is a crossing where two traits are taken into account that will be segregated independently by the parents, and the result can be obtained by analyzing their genotypes and making the corresponding crossing in a Punnett square.

Genotypes:

Male cat AABb
Female cat aabb

Crossing :

Punnett's square (simplified)

Alelles AB Ab

ab AaBb Aabb

Offspring:

AaBb amazing and bashful (heterozygous for two traits) 50%
Aabb amazing and boring (heterozygous for trait A ans homozygous recessive for B) 50%

Probability that they will have an offspring who is heterozygous for both traits is 50%.
