Which individuals in the pedigree are identified and labeled carriers for red-green color blindness?

Answers

Answer 1

Answer: Do you have the pedigree to share? Red green color blindness is an x linked trait, which means that it is found on the X chromosome. X linked traits are often recessive, and this is why they usually show up in males, such as the case of red green colorblindness. A male has only one copy of the X chromosome, so if a recessive x linked trait is present, he does not have the option of the dominant version of the trait to show up. A recessive X linked trait can present itself in a female, but since she has two X chromosomes, she would need to have two copies of the recessive trait for it to present itself. This is why color blindness is less common, but still possible in females. I hope this helps you with your pedigree.

Respiratory structures of land animals can include which of the following: A. Lungs B. Skin C. Gills D. Both A and B

Answers

Answer:

Option D

Explanation:

Animals on land get air directly from atmosphere. They need to extract it from any other sources like water animals use air dissolved in water or so. Lungs is the most prominent and essential organ of respiratory system of organisms that directly intake oxygen from atmosphere and release carbon dioxide back into the atmosphere.

However, all amphibians and some other creatures like earthworms uses skin as respiratory organ on land. They intake air through their permeable moist skin.

Hence, option D is correct

(Lungs & Skin), D. Both A and B

Why are the walls of the atria thinner than the walls of the ventricles

Answers

The blood is pumped down to the ventricles, which are larger pumping chambers which must propel blood out of the heart therefore, they contain more muscle tissues than atria do.
