Answer:
I think the answer is a plant cell contains one large vacuole in its wrong because they have a nucleus I did not all plants have the same size or shape and they only have one large vacuole or sap vacoule hope it helps
Answer:
Domains
Explanation:
Living organisms are divided into three domains:
Archaea
Eubacteria
Eukarya
Organisms are divided into these three domains based on genetic similarities or closeness. Archaea and Eubacteria are domains that consist of prokaryotes or prokaryotic cells.
Prokaryotes in the domain Archaea differ from those in Eubacteria because of certain characteristics like their ability to live in extreme environments and the absence of the peptiglycan in their cell walls.
Prokaryotes in the Eubacteria domain have peptidoglycan walls and RNA unique to them.
Organisms uner Eukarya, as the name suggests, have eukaryotic cells meaning the have an enclosed or membrane-bound nucleus.
Answer:
See the answer below
Explanation:
First of all, each genotype will produce games that will be aligned on both sides of the Punnet's square.
FfEe will produce FE, Fe, fE, and fe gametes. Hence, the Punnet's square showing the offspring from the dihybrid cross would be as attached in the image below.
A mix of red and white alleles would be Rr which is a red flower
Answer:
B) Heterozygotes are less susceptible to the malaria parasite, so there is an advantage to being heterozygous.
Explanation:
Sickle cell anemia is a recessive condition in which the red blood cells (RBCs) become sickle shaped. Due to the abnormal shape they are not able to transport oxygen efficiently which proves lethal for the person. Both, homozygous dominants and heterozygotes survive.
However in African countries with high rate of malaria, heterozygotes are selected over the dominant homozygotes. Dominant homozygotes have all normal RBCs which make them susceptible to malarial parasite since RBC is the host cell for it.
Heterozygotes produce some normal RBCs and some sickle shaped. Malarial parasite is not able to attack sickle shaped RBCs because of its unusual shape. So heterozygotes are less susceptible to malaria. Since they also have some normal RBCs, they are not affected much by sickle cell anemia too. Hence, heterozygotes evade both sickle cell anemia and malaria and heterozygous is the most advantageous genotype in this case.
