True or false, most lakes grow larger over time due to erosion?
ipn [44]

Answer: False

A lake is a water body that is surrounded by land. The water in the lake comes from melting glaciers, rain, groundwater, rivers. Lake formation also occurs when a water body is restricted to it's natural flow. Erosion due to wind  and water will limit the life of lake. As, soil removed during landslides or mudslides from hills or mountains get settled as debris at the bottom of lake will cause water pollution. Also, soil coming from agricultural field through water will carry in it fertilizers ,which will promote excessive plant and algal growth in lakes therefore, oxygen content of lake water will decrease which lead to death of animals residing in lake hence, will ultimately lead to water pollution ,which will be responsible for limiting the life of lake.

Achondroplasia is a form of dwarfism inherited as a completely dominant trait. Two achondroplastic dwarfs have a dwarf child; la
yulyashka [42]

Answer:

There's 25% probability that their next child will be normal, and 75% of it being a dwarf.

Explanation:

Achondroplasia (A) is a dominant trait.

Two achondroplastic dwarfs (A_ x A_) have a dwarf child (A_) and a normal child (aa). The second child must be aa because if it had a dominant allele it would also be dwarf.

The only way for two achondroplastic parents to have a normal child is that <u>they are both heterozygous (Aa) for this gene.</u>

The cross Aa x Aa would produce the following offspring probabilities:

  • 1/4 AA - dwarf
  • 2/4 Aa - dwarf
  • 1/4 aa - normal

So there's 1/4=25% probability that their next child will be normal, and 3/4=75% of it being a dwarf.

The leakiest capillaries, which allow large substances such as cells to cross the capillary walls are called?
ki77a [65]

The leakiest capillaries, which allow large substances such as cells to cross the capillary walls are called sinusoidal capillaries.

Sinusoidal capillaries are a unique kind of capillaries that are wide in diameter. The diameter of a sinusoidal capillary is 30 to 40 nm.

Sinusoidal capillaries can be found in the liver, spleen, and bone marrow. In the spleen, sinusoidal capillaries help in the filtration of blood. They remove broken red blood cells, antigens and other pathogens remains in the blood.

Sinusoidal capillaries are known as leakiest capillaries because all other capillaries have a narrow diameter and do not allow the passing of large substances. Sinusoidal capillaries are the only ones with a large diameter that allows the passing of larger substances.
