During the proliferative phase of the menstrual cycle,

1 answer:

7 0

The ovaries are works on developing the egg-containing follicles, the uterus is reacting to the estrogen made by the follicles, reva6mping the lining that was just rid during the last period. This is called the proliferative phase because the endometrium evolves thicker.

<h3>What is the proliferative stage?</h3>

In the proliferative phase, the fibroblasts make collagen that rises wound stability, new epithelial cells cover the wound area, and capillaries join to form new blood vessels.

In the late phase, the production of new and collagen remodels the scar, blood vessels widen, and the epithelium.

Thus, The ovaries are working on developing the egg-containing follicles, the uterus is responding to the estrogen produced by the follicles, rebuilding the lining that was just shed during the last period

Not all inspired air reaches the alveoli; 150 ml is stopped in the airway leading to the alveoli. this is called?

Igoryamba

Not all inspired air reaches the alveoli; 150 ml is stopped in the airway leading to the alveoli. This is called dead air space.

Alveoli are the tiny air sacs present all over the lungs. These are supposed to increase the surface area of the lungs so as to increase the amount of inhaled air. The exchange of oxygen and carbon dioxide takes place through these alveoli.

Dead air space is the unventilated area where air circulation does not take place. This air is supposed to be get trapped somewhere in the respiratory pathway or it reaches an alveoli that is poorly perfused. The dead air space can be of two types: anatomical dead space and physiologic dead space.

Propane is burned to provide the heat in many cooking grills. The chemical

tangare [24]

Answer: it's 3CO2+4H2O+Energy

Propane is a linear alkane of formula C3H8. It is mainly used as fuel (this is the main component of liquefied petroleum gas) in cooking and chemical industry reactions.

The reaction of its complete combustion by the presence of oxygen is:

C3H8 (gas) + 5O2 ==> 3 CO2 + 4H2O + energy (2220⋅kJ)

As we can see, propane can release carbon dioxide and water as every combustion reaction, and a lot of energy in the form of heat.

The testcross makes it possible to determine the genotype of an individual of unknown genotype who exhibits the dominant version

klio [65]

Answer:

All of the above answer choices are correct.

Explanation:

Test cross is done to find out the genotype of an individual displaying dominant phenotype as it can be homozygous or heterozygous. To find this the individual is crossed with a recessive phenotype individual. For example: a dominant trait tall height can be homozygous TT or heterozygous Tt. If it is TT all the offspring of test cross with tt will be tall. If it is Tt half of the offspring will be tall and half of the offspring will be short.

Multiple offspring are required to come to the final result because offspring production happens in random order and it might take a few tries before another type of phenotype is produced. For example: If a test cross produces an individual with dominant phenotype we can still not surely say if the test individual is homozygous or heterozygous because both can produce dominant phenotype in test cross. We need more offspring to check if the recessive phenotype is produced or not and accordingly decide the genotype of test individual.

Hence all of the above answer choices are correct.
