Answer:

The four steps of the menstrual cycle are as follows:

1. Menstruation: It is the eradication of the endometrium, that is, the thickened lining of the uterus from the body via the vagina. The menstrual fluid comprises cells from the lining of the uterus, blood, and mucus.

2. Follicular phase: The follicular phase begins on the menstruation's first day and terminates with evolution. It is mediated by the hypothalamus, the pituitary gland, which discharges FSH.

3. Ovulation: It is the release of a developed egg from the ovary surface. This generally takes place mid-cycle, around two weeks or so prior to the beginning of menstruation.

4. Luteal phase: At the time of ovulation, the egg erupts from its follicle, however, the ruptured follicle remains on the ovary surface. In the next two weeks, the follicle gets convert into a composition called corpus luteum.

A cousin who has been traveling overseas sneaks a plant through customs (who help along with the USDA, help to prevent invasive

Reil [10]

Answer and Explanation:

Invasive species are not native to an ecosystem/environment to which they've been introduced, which can cause disastrous disruptions to various food chains/webs and other native species' populations.

In this case, your cousin is bringing in a plant from overseas, so it clearly will be an invasive plant. You can tell them the following:

- this plant may take over the feeding source of native plants, causing those populations to decrease drastically or possibly even be wiped out

- secondary consumers that had once relied on those native plants for food energy will now have limited resources, competition will increase, and these consumers may begin to die off

- tertiary consumers that consumed these secondary consumers will begin to die off, as well

- this chain reaction will ripple through the entire food chain and food web, and totally disrupt the existing ecosystem

Thus, your cousin shouldn't plant this organism in their backyard and should instead destroy it.

Enzymes' specificity appears in their unusual three-dimensional structures. Like all enzymes, enzymes improve the reaction rate by decreasing its activation potential.
