Answer:

The question lacks options, the options are:

A. testicle B. epididymis C. penis D. vas deferens

The answer is Testicles or testes

Explanation:

Testis (plural-testes) is the male reproductive organ. It is responsible for producing the male sex cell or gamete. Sperm cells are produced by the division and differentiation of germ cells (a process called spermatogenesis) located in the seminiferous tubules, which is a tube-like structure located in the testicles. The testes is responsible for secreting the hormone, TESTOSTERONE, that catalyzes this process.

This sperm cell produced are still immature. They undergo development until maturity when they travel to another region of the testes called EPIDIDYMIS. Matured sperm cells finally leave the epididymis and becomes stored in the VAS DEFERENS, from where they mix with seminal fluid to form SEMEN and released from the male's penis.

When apparent competition occurs, the:

artcher [175]

Answer:

The correct answer is:

population of the predator species is larger and the populations of the prey species are smaller. (C)

Explanation:

apparent competition occurs occurs between two species or group of organisms that do not directly compete for resources affect each other indirectly by being prey to the same predator. For example consider three species of organisms; sparrows, earthworms and beetles, where earthworms and beetles are preys of the sparrows, an increase in the population of earthworms will in the long term lead to an increase in the population of sparrows, which means that more predators will be available, leading to a decrease in the population of beetles, because more predators are available to prey on them. Also a decrease in the population of earthworms will also lead to a decrease in the population of beetles because their probability of being seen by the predators will increase leading to an increase in their killing.

Therefore in apparent competition, although it occurs between two prey species, their in an increase in the number of predators and a decrease in the population of the prey.

Form a Hypothesis: As the map shows, the sickle cell allele is not found in African populations that are native to southern Afri

kati45 [8]

A hypothesis for this observation might be that malaria is not endemic to southern Africa. It is a plausible explanation of a given scientific question.

<h3>Hypothesis and scientific method</h3>

A hypothesis is a plausible explanation of an observation of the natural world, which must be tested by using the scientific method.

Testing a hypothesis involves performing additional observational and/or experimental procedures in order to confirm or reject this assumption.

In this case, the sickle cell allele is found in high frequency in regions where malaria is endemic.

In a certain species of plant, the allele to produce green melons (G) is dominant over the allele to produce yellow melons (g).

marishachu [46]

Answer:

4.26

Explanation:

Let the green-melon parents be Gg, then we expect the cross with the yellow-melon plant gg so as to produce 50% Gg and other 50% of gg offspring. What we observed was that 53 green and a 41 yellow. Based on the total number of 94 offspring , we expected half and a half ratios to be 47 of each color.
