It was earlier introduced to Lake Victoria but after sometime it was evaluated that native fishes got extinct and the Nile Perch become very huge in size.

<u>2. The cotton whitefly: </u> Cotton whitefly are native to India but now can be found on most of the continents and have very bad impact on the fauna or agricultural plants. They have capability of transmitting upto 100 different plant viruses. find them thriving

<u>3. The desert locust:</u> The desert locust is a species of locust which can fly and are one of the most disastrous migratory pests in the world. They feed over green green vegetation, including pasture, crops and fodder. They have very bad impact on native flora as they are migratory pests. They are found in Africa and migrated to nearby countries such as India and damages the native flora.

NEED HELP ASSAAPP!!!! 2. What protein changes shape in sickle cell anemia? What are two effects of this change?
mixer [17]

Answer:

Hemoglobin

Explanation:

Hemoglobin is a protein in red blood cells that carries oxygen throughout the body. With SCD, the hemoglobin forms into stiff rods within the red blood cells. This changes the shape of the red blood cells. The cells are supposed to be disc-shaped, but this changes them into a crescent, or sickle, shape.

The sickle-shaped cells are not flexible and cannot change shape easily. Many of them burst apart as they move through your blood vessels. The sickle cells usually only last 10 to 20 days, instead of the normal 90 to 120 days. Your body may have trouble making enough new cells to replace the ones that you lost. Because of this, you may not have enough red blood cells. This is a condition called anemia, and it can make you feel tired.

The sickle-shaped cells can also stick to vessel walls, causing a blockage that slows or stops the flow of blood. When this happens, oxygen can't reach nearby tissues. The lack of oxygen can cause attacks of sudden, severe pain, called pain crises. These attacks can occur without warning. If you get one, you might need to go to the hospital for treatment.

A bird is flying in the air at a 4 m/s. If the mass of the bird is 7kg what is it’s kinetic energy
yaroslaw [1]

Answer: The kinetic energy of the flying bird is 56 Joules.

Explanation:

Mass of the bird  = 7 kg

Velocity of the flying bird = 4 m/s

Kinetic energy of the bird will be given by :

K.E.=\frac{1}{2}mv^2

K.E.=\frac{1}{2}\times 7 kg\times (4 m/s)^2=56 Joules

The kinetic energy of the flying bird is 56 Joules.
