Describe how climate would be influenced if:

madam [21]

The rate of energy coming from the Sun changes slightly day to day. .It has been suggested that changes in solar output might affect our climate—both directly, by changing the rate of solar heating of the Earth and atmosphere, and indirectly, by changing cloud forming processes.
The axial tilt angle affects climate largely by determining which parts of the earth get more sunlight during different stages of the year Likewise, during winter for the northern hemisphere, there would be fewer hours of daylight because the northern hemisphere would essentially be pointed away from the sun.
If an asteroid were to strike land or a shallow body of water, it would eject an enormous amount of dust, ash, and other material into the atmosphere, blocking the radiation from the Sun. This would cause the global temperature to decrease drastically.
The Sun's irradiance has its greatest effect on Earth's upper atmosphere, while the lower atmosphere insulates Earth from the increased heat. If the Sun were driving Earth's warming, one would expect to see that upper atmosphere getting increasingly hot.\
have a nice day sorry if wrong T_T

Calculate the population. There is a flock

laiz [17]

Answer:

C. Population shrinks; 15 birds in the end

Explanation:

Let us understand some of the given terms;

immigration is a form of migration in which organisms comes into a territory.

emigration is a form of migration in which organisms leaves a place

population is a group of organisms of the same species

Given:

Population = 21 birds

Immigrant = 3 birds

Emigrants = 9 birds

Population change = total number of birds + immigrant - emigrants

= 21 + 3 - 9

= 15 birds

The population will shrink giving 15 birds in the end

Which of the following are TRUE statements about red blood cells (erythrocytes)?

Romashka [77]

Answer:

The correct answer will be options A, B and E.

Explanation:

Red blood cells or RBC or erythrocytes are the cells present in the connective tissue which forms the blood. RBC perform various functions in the body but the primary function is the transport of the gases in the body.

The RBC are continuously formed in the bone marrow region of the bone form the hemopoietic stem cell found in the bone marrow. These cells produce a large amount of RBC that is about 2 million cells per second in a healthy adult.

When RBC are formed posses nucleus but when mature, they lack nucleus that is genetic material and organelles like mitochondria so, they are not able to divide.

These RBC contain haemoglobin in their cytoplasm which shows high affinity to bind oxygen and low affinity to bind carbon dioxide to the iron group of haemoglobin.

Thus, options A, B and E are the correct answer.
