What general shape do water molecules have?

Which pair is mismatched? Multiple Choice Trypanosoma - causes African sleeping sickness Giardia - transmitted by feces in drink

Grace [21]

Answer:

Trypanosoma ------------ causes Chagas disease.

Trypanosoma -------------- causes African sleeping sickness.

Giardia --------------------- transmitted by feces in drinking water.

Trichomonas ------------ sexually transmitted.

Histoplasma ------------- causes Ohio Valley fever.

Explanation:

- Trypanosoma cruzi is a parasite transmitted by the bite of an insect of the Triatominae subfamily, very common in rural areas. It causes weakening of the heart muscle and heart failure, characteristic of Chagas disease.

- Trypanosoma brucei is a hemoparasite - found in the blood - transmitted by the tse-tse fly. Causes African trypanosomiasis or African sleeping sickness, characterized by progressive involvement of the central nervous system.

- Giardia lamblia is a parasite that is predominantly found in the duodenum. Infestation by this biological agent produces abdominal pain, nausea and belching with an unpleasant taste. It is transmitted by water contaminated with feces.

- Trichomonas vaginalis is a parasite that is transmitted through sexual contact, and produces vaginal trichomoniasis, a disease that causes inflammation and secretion in the genitals of men and women.

- Histoplasma capsulatum is a fungus that produces the disease called Ohio Valley fever (histoplasmosis), characterized by cough with expectoration, respiratory distress, fever, headache and severe muscle aches.

In early spring, many wildflowers begin to grow,

Musya8 [376]

In early spring, many wildflowers begin to grow, produce flowers, and release seeds. The leaves of the wildflowers make food before the leaves of the trees in the area begin to develop. The early growth pattern of the wildflowers would likely result in decreased competition for sunlight between the trees and the wildflowers (1). There is a good reason why the wildflowers grow so much earlier than the trees. If they start growing at the same time in spring, then the tree leaves will block out the sun for the wildflowers.

Let’s assume that dragons show incomplete dominance for fire breathing. The F allele provides lots of fire and the F’ allele giv

laila [671]

The progenies of the dragons with strong fire and dragon with no fire will be dragons with fire at medium rate.

<h3>Explanation:</h3>

Incomplete dominance is the phenomenon when two different alleles are present in a same organism gives a mixed type of phenotype which isn't similar to any characters of the parents.

In case of the dragons, the genotype of the dragons with strong fire = FF.

The genotype of the dragons with no fire = F'F'.

So the gametes produced by the dragon with strong fire is F and that by the dragons with no fire is F'.

So the dragons produced as a progeny = FF'.

As this gene shows incomplete dominance, so both the characters will be mixed and present as a mixed character. So the offsprings will be moderately fire breathing.

When DNA is duplicated during mitosis

serg [7]

Answer:

Replication and Distribution of DNA during Mitosis. ... This process involves replication of the cell's chromosomes, segregation of the copied DNA, and splitting of the parent cell's cytoplasm. The outcome of binary fission is two new cells that are identical to the original cell.

Some bacteria live in the roots of plants like soybeans and peas. What is the role of these bacteria in the nitrogen cycle.

love history [14]

Answer:The nitrogen present in the soil is not directly used by the bacteria. It can be used only when the nitrogen is converted into usable form. These bacteria convert atmospheric nitrogen into ammonia, then nitrite which is then converted into nitrate. This nitrate is used by the roots of the plants like soybeans and peas. This is the role of bacteria present in the roots of the plant to convert atmospheric nitrogen into usable form that can be used by plants.
