the correct answer might be neuro-toxin
Fungal Parasites,
specifically basidiomycetes causes various infectious diseases that destroys
billions of dollars of food crops annually with worldwide impact. The 1972 U.S.
corn crop was almost completely destroyed by a fungus and during the late 1990s
most wheat fields in Arizona had to be devastated due to the existence of
fungal parasites. This clearly suggest that the presence of fungal
parasites resulted in loss or reduction of food crops.
Furthermore, basidiomycetes are
called club fungi, which is part of a <span>major group of fungi that produce a basidium
structure that includes mushrooms and toadstools. Although, they have economic
use in pharmaceutical industry such as producing penicillin and provide us food
like cheese, mushroom, in baking and in brewing, there negative impact must
also be consider and should be handle appropriately to eradicate crop
destruction.</span>
Answer:
a. all tall
Explanation:
If genotypically one of the parents is homozygous dominant and another one is heterozygous for plant height then phenotypically all their progeny will be tall.
Let us suppose, 'T' represents dominant allele and 't' represents recessive allele. Then the genotype of one parent who is homozygous dominant will be TT and genotype of another parent who is heterozygous will be Tt.
The cross is depicted in the attachment.
Here it may also be noted that genotypically two of the progeny will be homozygous dominant while two of the progeny will be heterozygous but phenotypically all the progeny will be 'tall'.
The question is incomplete. The complete question is:
"In Graves disease, thyroid-stimulating immunoglobulins (TSI) contain an active site that can mimic the active site of TSH to stimulate thyroid hormone production. One would expect TSI to cause:"
A. An increase in thyroid gland size because of the trophic effect of TSH.
B. A decrease in thyroid gland size because of competitive inhibition with TSH.
C. No change in thyroid gland size because antibodies only recognize foreign particles.
D. An immune response against TSH molecules.
Answer:
A. An increase in thyroid gland size because of the trophic effect of TSH.
Explanation:
Thyroid-stimulating hormone is a trophic hormone and is released by the anterior pituitary gland. It targets the thyroid gland and stimulates it to release the thyroid hormones. Graves disease is an autoimmune disorder in which the person produces antibodies such as thyroid-stimulating immunoglobulins that mimic the action of thyroid-stimulating hormone (TSH).
These antibodies continually stimulate the thyroid gland to grow and produce thyroid hormones. The result is an abnormally enlarged thyroid gland. The affected individuals also develop peculiar edema behind the eyes that causes the eyes to protrude.
