What causes the formation of a cervical plug a testorone b progesterone c luteal d estroge e follicle

Biology

nlexa [21]3 years ago

Answer: The correct option is B (progesterone).

Explanation:

The cervix is the ring of muscles also called the neck of the uterus in female reproductive system. This protrudes through the anterior wall of the vagina, opening into it at the external os.

After the fertilization of the ovum by the spermatozoa, the uterus prepares for the implantation which results from the secretion of hormones. Under the influence of oetrogen, secreted by the developing follicle, the cells of the endometrium divide rapidly causing the endometrium to build up and thicken.

While the viscosity of cervical mucus changes in response to hormone levels and during pregnancy, progesterone fosters the production of highly viscous mucus resulting in the formation of a plug that forms a physical barrier to bacteria and prevents their ascension into the uterine cavity. This plug is called CERVICAL PLUG.

Answer:

b progesterone

Explanation:

The plug is formed as soon as there is implantation of fertilized eggs. The thickness of the cervical mucus becomes different as hormone levels changes in pregnancy.  

The progesterone, encourages the production of thick fluid/ mucus  which brings about the formation of a plug. This prevents bacteria from getting into the uterine cavity.

DDT is an insecticide that was formerly used to control insects that would eat crops. It was banned from use in the 1970s.
Reil [10]
<h2>It contains toxins</h2><h2>It killed off bird populations.</h2><h2>It caused harm to human populations.</h2>

Explanation:

Let us understand the term DDT

DDT : Dichlorodiphenyltrichloroethane

  • This is a crystalline chemical compound
  • Basically used for protecting insects eating crops
  • It is colorless, odorless, tasteless
  • Initially used as pesticides

It killed off bird populations: Though it does not kill birds directly by consuming, it has indirectly damaged the egg by making the egg's shell too thin which gets broken easily.

It controlled diseases like malaria: Since this option talks about positive attribute of DDT, this option stands invalid. This chemical compound controls mosquitoes attacking the crop.

It caused harm to human populations: DDT causes vomiting, tremors or shakiness, and seizures

It contained toxins: It contains moderate toxins.

What is an effective recovery plan for the rehabilitation of endangered species?​
Mashcka [7]

Answer:

An endangered species recovery plan is a document describing the current status, threats and intended methods for increasing rare and endangered species population sizes.

Explanation:

When recovery plans are carried out well, they do not simply act as stop gaps to prevent extinction, but can restore species to a state of health so they are self-sustaining. There is evidence to suggest that the best plans are adaptive and dynamic, responding to changing conditions. However, adaptive management requires the system to be constantly monitored so that changes are identified.[10] Surprisingly this is frequently not done, even for species that have already been red listed.[11] The species must be monitored throughout the recovery period (and beyond) to ensure that the plan is working as intended. The framework for this monitoring should be planned before the start of the implementation, and the details included in the recovery plan. Information on how and when the data will be collected should be supplied.

Suppose white and brown fur in a species of rodent were due to different alleles at the same gene. An F1 cross between true bree
svetlana [45]

An F1 cross between true breeding brown and white lines is set up. What evidence would best support white fur being dominant to brown -----

The best evidence to show that white fur being dominant is when all the offspring after the cross are white instead of brown

They are therefore expected to produce heterozygous lines.

The evidence that would best support white fur being dominant is when all the lines produced are white despite being heterozygous.

A dominant trait is known to mask the expression of other traits.
