When a primary follicle enlarges, and there are several layers of granulosa cells, it is called a:.
A follicle with a single layer of cuboidal granulosa cells is called a primary follicle. A follicle with more than one layer of granulosa cells is called a secondary follicle. Eventually, fluid-filled vesicles occur n the granulosa cell layer, forming early antral follicles.
What is a secondary follicle?A secondary ovarian follicle is a maturing ovarian follicle including of an oocyte encircled by two or more layers of tall, keeping granulosa cells.

The ability for people to roll their tongue is dominant to people who cannot. If a tongue roller and a non-tongue roller were crossed, the highest percentage of potential non-tongue roller offspring would be which of the following?
Answer:
50%
Explanation:
Tounge rolling is a dominate trait, so that means it would have to have at least 1 captial letter in it't genotype (assuming captial letters refer to the dominate trait). But, because the demonate trait covers any non-dominate traits, you can have a lower case letter in the genotype while still having someone be a tounge roller (assuming lower case letters are non-dominate traits)
Because non-tounge rollers are non-dominate, they must have two lower case letters in their genotype.
This leaves you with the two genotypes of :
AA or Aa (tounge rollers)
aa (non-tounge rollers)
When crossing AA with aa in a punette, every outcome is Aa. This leaves you with no potentional non-tounge rollers. But, you can still cross Aa with aa, because as said before Aa has a dominate gene, so it would result in someone with the tounge rolling ability.
When crossing Aa and aa in a punnet sqaure, you can get outcomes. Aa or aa. 2 of teh 4 options are Aa, and 2 of teh four options are aa. This means half, or 50% of the offspring are predicted to be non-tounge rollers, showing the high ercentage must be 50%.

Which structure is an important site for early blood cell formation and is the first of the extraembryonic membranes to form
Yolk sac is a structure that has a short duration in intrauterine development and is an important site for early blood cell formation.
What is the yolk sac?It is the bag that houses yolk inside and that allows the embryos of certain species to feed in the initial stages of development.
Due to this structure, the embryo receives oxygen and nutrients and can discard its waste, in the case of the human being, the yolk sac fulfills the functions of the circulatory system, until the internal circulation begins to develop.
Therefore, we can conclude that the yolk sac is a structure that has a short duration in intrauterine development and is an important site for early blood cell formation.

Where does the energy in a food web come from or originate?.
Answer:
The energy in the food web ultimately originates from the sun. Energy travels from the sun to the earth in the form of electromagnetic radiation. Autotrophs (primary producers) are able to capture this energy and convert it into sugar molecules via photosynthesis. These sugar molecules provide the energy that travels up the food chain as consumers eat other organisms.
So, the answer is: The Sun.
