I believe the answer would be C. codons
Answer:
The answer to 1. is option a. asexual portion.
The answer to 2. is option b. sexual portion.
The answer to 3. Is option a. Mosquito
Explanation:
1. The asexual portion is the stage in the Plasmodium erythrocytic cycle where the parasite develops in the erythrocytes causing accumulation of waste and toxic substances which ultimately end up in the bloodstream when the infected cells lyse. These factors acts to produce the symptoms experienced in malaria.
2. During the sexual portion of the Plasmodium cycle spores formed in the human host are released into the bloodstream which is usually picked up by an uninfected female anopheles mosquito when it takes a blood meal.
3. An infected mosquito passes the sporozoites to a new human host when it takes a blood meal and the cycle starts all over.
Answer:
large central vacuole
cell wall
Explanation:
Let me clear some things up for you. There are two types of cells - Prokaryotes and Eukaryotes. The principle difference between these types of cells are the structure of their genome. In case of prokaryotes, the genomic matter do not have a defined structure, it just kind of floats around in the protoplasm. But in the eukaryotes, the genome is more structured, have all kinds of proteins associated with them, and is surrounded by a two layered sack called the nuclear membrane. Both plant and animal cells have these feature of structured nucleus, therefore, they are both eukaryotes.
Now for the difference between plant and animal cells. the features you mentioned are unique about plant cells, but do not rule them out from being eukaryotes, as the 'true' structure of the nucleus is still there. Cell walls are necessary for the plant cells because plants do not posses an endoskeleton like most of the animals do. The cell wall makes the whole plant rigid so they don't fall apart or appear like a blob. Chloroplast is where photosynthesis happens, so it should most definitely be in a plant cell. Animals don't do photosynthesis so they don't have chloroplasts. Vacuoles are also present in animal cells, but they are much smaller, greater in number, and are known as lysosomes. Functionally they are virtually the same.
<span>The mechanism that affected the gene pool of the immigrants that entered the United States through Ellis Island from 1892 to 1954 is B. gene flow. Gene flow is the transfer of genes or alleles from one population to another. The migration of millions of individuals from countries across the Atlantic Ocean to the United States is responsible for the changes in the gene pool of the immigrants.</span>
