Smut are plant disease caused by
several species of fungi that affects plants such as, corn, wheat, and sorghum.
Smut is characterized by fungal spores which are infectious and can affect
different parts of the plant at the same time. The fungi attacks grain crops by
forming thick, fleshy, gall on the ear, tassel, stalk and leaves of the plant. Smut
are destructive to grain crops, with negative economic effects to the farmer.
The answer is weathering.

Answer:
Option 1, 0
Explanation:
Complete question
Flower color in the varieties of pea plants studied by Mendel is controlled by alleles at a single locus. A group of peas homozygous for purple flowers is grown in a garden. All flowers are purple, yet there is some variation in the intensity of the purple color. The estimated heritability for this observed variation in flower color would be
- 0.
- 0.5.
- 0.75.
- 1.
- Cannot be determined without additional information
Solution
Given all the pea plants in the garden are homozygous purple (PP)
If we cross two PP parents, the following offspring will be produces
PP * PP
PP, PP, PP, PP
This means that all offspring are also homozygous purple.
Thus, chances of inheriting variation in the purple color of offspring are negligible. However, the variation in their color can be due to their individual interaction with the variable factors in the environment
Hence, option 1, 0 is correct
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.
