Ingestion of foreign substances by macrophages and yeast cells by an amoeba is known as
Iteru [2.4K]

Ingestion of foreign substances by macrophages and yeast cells by an amoeba is known as <u>Phagocytosis</u>

<u>Explanation:</u>

Phagocytosis that is the name given to the process of ingestion of foreign particles by macrophages. In human body the white blood cells does this function. Macrophages is found in all the tissues. Any foreign particle entering the body is engulfed by this process hence protecting the organisms.

Once a bacteria enters the body it is at once detected and recognised as the foreign particle. Then it is attached to the phagocyte. Then it is engulfed into a vesicle called phagosome. Then this is killed by the process of phagocytosis.

the data collected over the years clearly confirm depletion of ozone in the stratosphere. what do scientists still need to learn
Lisa [10]

<span>Ozone is simply a molecule consisting of 3 oxygen atoms, which reacts strongly with other molecules. Ozone is created in the stratosphere when high energy uv radiation causes on O2 molecule to split. The free oxygen atoms collide and react with other O2 molecules to form O3.</span>

Production is highest where the solar uv is the greatest eg near the tropics, but once created, the ozone is then circulated towards the poles by the atmosphere. The amount of ozone in the stratosphere can vary with location, season and even day to day climatic conditions.

<span>The process of ozone creation is what makes the O3 in the atmosphere very effective at shielding the Earth from harmful uv radiation, which can cause many biological problems, such as skin cancer. However, due to its high reactivity, the uv found in the tropospher at ground level can aslo be dangerous as a toxic pollutant which is harmful to plants and lung tissue, and is a major cause of smog.</span>

A grasshopper jumps along a line. His first jump takes him 1 cm., the second 2 cm, etc. Each jump can take him to the right or t
loris [4]

Answer:

The grasshopper cannot be in the same location it started because by 2017, it would have covered a distance of 1017576.5 to either left or right. and that distance is not an integer.

Explanation:

The grasshopper jumps in integer of 1 cm to either right or left

Calculating for the total distance covered in 2017 jumps

Total Distance = (2017 x 2018)/2 = 2035153 cm

To either right or left: this implies that the total distance be divided by 2

=> 1017576.5 cm

It shows that at some point, the grasshopper will not be in a position of integer on either right or left.

Therefore, it can not get to its initial point of start.
