Answer:

A. an embryo sac

Explanation:

Angiosperms or flowering plants produce their gametes through the meiosis.

In the ovule (contains female reproductive cells) a diploid cell (megaspore )undergoes meiosisin which four cells (megaspores) with haploid nuclei are produced. One of these four megaspores then undergoes three successive mitotic divisions to produce an immature embryo sac which is the megagametophyte with 8 haploid nuclei (3 antipodal cells, 2 synergid cells, 1 egg cell and 2 polar nuclei).

Name the difference between a food chain and a food web. Also state a few animals role in the food chain and food web.
Brums [2.3K]
The food chain in a visual representation of how energy is flowed through out a specific environment. While it is very similar to the food web, the main difference is that the web gives a more broad wide range of organisms and it is more specific with what eats what. The second part of your question about a few animals roles umm... Grass is a producer which has the role of feeding primary consumers, it is the base of the chain or web without it the whole thing would collapse. Tertiary consumers such as owls have the role of eating secondary consumers. I always thought of it like the tertiary consumers are population control since nothing eats them they have no responsibility to feed other organisms just make sure that secondary consumers don't overpopulate.

How does central retina differ from peripheral retina differ?
Musya8 [376]
When an ophthalmologist uses an ophthalmoscope to look into your eye he sees the following view of the retina

In the center of the retina is the optic nerve, a circular to oval white area measuring about 2 x 1.5 mm across. From the center of the optic nerve radiates the major blood vessels of the retina. Approximately 17 degrees (4.5-5 mm), or two and half disc diameters to the left of the disc, can be seen the slightly oval-shaped, blood vessel-free reddish spot, the fovea, which is at the center of the area known as the macula by ophthalmologists.
