What are hyphae made of
postnew [5]
Structure. A hypha consists of one or more cells surrounded by a tubular cell wall. In most fungi, hyphae are divided into cells by internal cross-walls called "septa" (singular septum). Septa are usually perforated by pores large enough for ribosomes, mitochondria and sometimes nuclei to flow between cells.

Allisa [31]

\huge\mathbb\colorbox{black}{\color{yellow}{AnSwEr}}

In humans, the medulla region of the brain is mainly responsible for the regulation process of respiration. It is also called the respiratory rhythm centre. The chemosensitive area located near the respiratory centre sends signals across nerve impulses to alter the rate of expiration to eliminate compounds.

Who is most in danger from the effects of overfishing ?
faltersainse [42]

I don't think we can answer this question just like that. The question should be formulated a bit differently:

WHAT is in danger from the effects of overfishing?


Well, in the end of the "effect-spectrum" we are in danger, since we also eat fish. But the most affected species are the ones that form the aquatic ecosystems. Such as fish. Examples:

1 - Many of the fish we eat, feed on sea-weed. If there aren't enough fish to eat the growing population of sea-weed, many fish die of intoxication.

2 - We don't have almost any fish restrictions in a way, because we can eat basically all of them. Therefore, many fish (which are also being eaten) find themselves in a lack of food.

3 - Many times, we concentrate on a specific species, which is a main cause of the extinction of species.



Hope it helped,

A dot is drawn every second to show the position of a toy car coasting up a ramp. Which statement best describes the motion of t
lbvjy [14]

It is speeding up because more distance is covered every second.

Explanation:

The car can be described to be speeding up because more distance is covered every second.

From what we understand about velocity and acceleration, the car is accelerating through the ramp.

It's velocity is increasing with every second it covers.

This will invariable reduce the time between each distance covered.

Originally, the toy car starts with a low initial velocity or speed. As it gains acceleration, the speed will increase and more distance covered per seconds.

This is why the dots clustered towards the end of the diagram. The positions are getting closer and distance reducing per seconds.
