Sarah and Thomas are thinking about having kids. They are concerned that because Thomas’s father was diagnosed with cystic fibro

sis last year, it could run in the family. Cystic fibrosis is a recessive genetic disorder which affects the respiratory system. Both Thomas and Sarah get tested for the recessive allele (f), with the results indicating that they are each carriers of the disorder (a genotype of Ff).
Is it possible for Sarah and Thomas to develop cystic fibrosis?

It is not possible for Sarah and Thomas to develop cystic fibrosis but it would be possible for one of their children to inherit it. Both Sarah and Thomas are heterozygous and in a heterozygous pair of alleles the dominant allele is the one that will present. Because Sarah and Thomas both have the heterozygous allele combination Ff they are carriers which means that they will not experience symptoms of cystic fibrosis but they could pass cystic fibrosis onto one of their children.

Cell biologist, Dr. Martine Dinen, is observing an organism's cell using a transmitting electron microscope. She notices that wi
Assoli18 [71]

The cell is most likely prokaryotic because:

Prokaryotes lack membrane-bound organelles such as the nucleus due to which the DNA are seen throughout the cytoplasm.

Eukaryotes have membrane-bound organelles such as the nucleus. So for eukaryotes, the DNA will be present packed inside the nucleus instead of being dispersed in the cytoplasm.

Prokaryotes can either be autotrophic or heterotrophic depending on their mode of nutrition. Autotrophic prokaryotes can make organic molecules for a carbon dioxide source. On the other hand, heterotrophic prokaryotes can take carbon from organic compounds. Hence, the organism can be autotrophic or heterotrophic.

What number represents a Ribosome? What is the function
Oduvanchick [21]

Answer:

A ribosome is a complex molecular machine found inside the living cells that produce proteins from amino acids during the process called protein synthesis or translation. The process of protein synthesis is a primary function, which is performed by all living cells. Ribosomes are specialised cell organelles and found in both prokaryotic and eukaryotic cells. Every living cell requires ribosomes for the production of proteins
