The Siberian Husky is a medium dog, weighing between 16-27kg (35-60lbs). These dogs have strong pectoral and leg muscles, allowing them to move through dense snow. If they had heavier muscles, they would sink deeper into the snow and move slower. Yet, if they had lighter muscles, they would not be strong enough to pull sleds and equipment. This is an example of which type of natural selection? A)Directional selection B)Stabilizing selection C)Disruptive selection

Which best describes genetic mutations? Some inherited genetic mutations can be good for the offspring. Different genetic mutations cause few forms of cancer. Somatic mutations can be inherited from parents or acquired during life. Genetic mutations that cause diseases are always passed on to offspring.

Answers

Genetic mutations are the changes in the genetic code and composition of organisms.

Genetic mutation can occur due to many factors like insertion, deletion, inversion of chromosomes.

The correct answer is:

Option A. Some inherited genetic mutations can be good for the offspring.

  • Mutations can be advantageous, inert or dangerous based upon the location of the genes.

  • Some mutations like in the case of sicklecell anemia in some communities conferred them resistance towards malaria disease.

  • The mutation can be beneficial as it can raise the chance of survival of the offspring.

Therefore, some inherited geneticmutations can be good for the offspring.

Which of the following best describes the structure of the sides of the DNA molecule? a double helix b alternating c single helix d twisted

Answers

a double helix best describes the structure of the sides of the DNA molecule. The correct option is A.

Thus, Deoxyribonucleic acid, or DNA, has a double helix-like structure. It is made up of two lengthy nucleotide strands that are spirally coiled around one another.

The complementary nitrogenous bases adenine (A) and thymine (T) and cytosine (C) and guanine (G) form hydrogen bonds that hold the two strands together.

This double helix structure is frequently compared to a spiral staircase or a twisted ladder.

Thus, a double helix best describes the structure of the sides of the DNA molecule. The correct option is A.

a defect in which of the following molecules would dramatically reduce the rate of diffusion of water across cell membranes?

Answers

A defect in the aquaporin molecule would dramatically reduce the rate of diffusion of water across cell membranes.

Aquaporins are a type of protein that form channels in the cell membrane, allowing for the rapid diffusion of water across the membrane. These proteins are essential for the movement of water in and out of cells, and play a crucial role in regulating the balance of fluids in the body. If there is a defect in the aquaporin molecule, the rate of diffusion of water across cell membranes would be significantly reduced, leading to potential problems with fluid balance and cell function.

In summary, a defect in the aquaporin molecule would dramatically reduce the rate of diffusion of water across cell membranes, potentially leading to problems with fluid balance and cell function.

Bright-field microscopes are used for most microscopic work. True or false?

Answers

Answer:

The correct answer will be option-true

Explanation:

A bright-field microscope is an optical instrument widely used by students and researchers all over the world.

The bright-field microscope is a compound light microscope which uses the light to see the samples. In the microscope the samples appear darker in color on the bright or light-coloured background.  This enables the viewer to clearly see the sample in the microscope.

Thus, true is the correct answer.
true, Bright-field microscopes are used for most microscopic work.
