Answer:

Yes, it accelerates

Explanation:

We have that:

The ball was stationary implies that its initial velocity, u = 0

It gained 5m/s means that its final velocity, v = 5m/s

Using first law of newton, we can determine whether it accelerates or not.

v = u + at

Substitute values for v and u

5 = 0 + at

5 = at

Make a the subject

a= \frac{5}{t}

<em>This implies that the ball accelerates over a period of time t</em>

<em></em>

Another way to tell if it accelerates or not is to consider the change in velocity.

When there is an increment in velocity of an object, the object accelerates.

In this case, the velocity increases from 0 to 5. Hence, we can conclude that it accelerates

Tpy6a [65]

Gulliver was a surgeon and he was on the ship named “Antelope”. When a violent storm came and the ship sank, all the crew members were engulfed in the ocean. Gulliver somehow managed and swam to the shore.

He was so tired that soon he fell into a deep sleep and when he woke he saw that he was caught and chained by little men called Lilliputians who lived there.

Sever21 [200]

When a fish swims from salt water into fresh water its cells react by losing water and shrinking.​ The correct option is D.

<h3>What is fresh water?</h3>

Glaciers, lakes, reservoirs, ponds, rivers, streams, wetlands, and even groundwater contain fresh water.

These freshwater habitats cover less than 1% of the world's total surface area but are home to 10% of all known animals and up to 40% of all known fish species.

When a fish swims from salt water into fresh water its cells react by losing water and shrinking due to osmosis.​

Thus, the correct option is D.

B. Green


Chlorophyll is found in and around the photosystems embedded in the thylakoid membrane of the chloroplasts.

The chloroplasts are organelles found in eukaryotic algae. The chloroplasts in eukaryotic celss are contained in the cytoplasm together with other organelles.

<span>Since the chlorophyll is insided the chloroplast which is inside the cytoplasm, it is safe to say that the chlorophyll of the green algae is spread throughout the cytoplasm of its cells.</span>
