Why would a diverse community be more resistant to disease, predation, and invasion

Shtirlitz [24]

Answer and explanation;

-A diverse community would be more resistant to disease, predation, and invasion because it would be a bigger diversity of genes, which means that the chance of disease would be more likely to spread in a different area than in a diverse population.

-Diversity is expected to increase the resilience of ecosystems. A diverse community would be more resistant to disease because of simple biology. The more sources for possible resistance the better the heterogeneous pool will be at resisting disease.

-High diversity strengthens a community and prevents invasion of the introduced predator. After a gradual loss of native species, the introduced predator can escape control and the system collapses into a contrasting, invaded, low-diversity state.

Juli2301 [7.4K]

Answer:

In babies born with congenital defects during the German measles rubella epidemic the specific cause of these birth defects was most likely the development of rubella virus infections in embryos.

Explanation:

Options for this question are:

1. The development of rubella virus infections in embryos. 

2. The failure of zygotes infected with rubella to develop

3. Mutations in the nerve cells of pregnant females at the time of the rubella epidemic .

4. An increase in the amount of time needed for healthy embryonic development.

Rubella is a viral infection caused by a virus of the genus Rubivirus, considered highly teratogenic during the phases of pregnancy where the embryo and the fetus are developing, that is, before 20 weeks of gestation.

The virus is transferred to the embryo or fetus by the mother's blood, acquiring the disease, which can cause abortions or visible malformations at birth, which is called Congenital Rubella Syndrome (CRB).

CRB is responsible for producing cardiovascular, renal, neurological malformations, loss of vision or hearing, problems that German children born during the epidemic probably had.

Mrac [35]

The small, almond-shaped organs of the female reproductive system, suspended by ligaments in the upper lateral portion of the pelvic cavity are known as ovaries.

Ovaries are oval-shaped so are also termed almond-shaped organs and are present on the sides of the uterus in females. In females, the processes of pregnancy and ovulation which is also termed menstruation are controlled by the hormones that are made by ovaries. These hormones include estrogen and progesterone. Another major function of the ovary is that it releases the female gametes known as eggs during the menstrual cycle.

The ovaries are attached to two types of ligaments which are the ovarian ligament and suspensory ligament. Ovaries are connected to the womb by the ovarian ligament while the suspensory ligaments of the ovary contain the ovarian vessels and nerves.
