A warming effect on earth
Explanation:
An increase in the concentration of greenhouse gases in the earth's atmosphere will cause warming of the earth surface. Examples of these gases are carbon dioxide, methane, water vapor e.t.c
- Greenhouse gases leads to the warming of the surface by trapping solar radiation and preventing them from escaping back into the outer reaches of the atmosphere.
- The trapped radiation causes warming of the earth surface.
- This is known as the global warming.
- Global warming leads to warming of the earth surface and melting of polar ice.

<h2>Answer:</h2>
The option A, B and E are correct.
<h3>Explanation:</h3>
Homeostasis is the ability or tendency to maintain internal stability in an organism to compensate for environmental changes. An example of homeostasis is the human body keeping an average temperature of 37 C degrees.
Homeostasis, any self-regulating process by which biological systems tend to maintain stability while adjusting to conditions that are optimal for survival.
So for the existence of living organism homeostasis is important.
Statements A, B and E apply to the definition of homeostasis.
Answer:
Intraspecific Competition
Bloodstain shape is determined by the angle between the flight path of the droplet and the surface that it impacts (Fig.1). When a drop of blood strikes a horizontal surface from the perpendicular (at an angle of 90°, Fig.2), the resulting bloodstain will be round. As the angle between the blood drops’ flight path and the target surface decreases, the length of the resulting bloodstain increases and the width decreases; in other words, the bloodstain becomes longer and narrower as the size of the angle decreases (Fig.3). A blood drop that has impacted a target surface from an angle of 12° will be long and narrow (Fig.4). Also present on these long, narrow stains is a ‘tail’ (Fig. 4). As the drop of blood impacts the target surface, the main body of the droplet will stick to the surface. A small portion of the blood drop will tear off from the top and continue in a forward direction. This secondary spatter has the appearance of a tail.
Other physicists would probably perform it to test if his conclusion from the data was correct, and to test to see if the data is consistent with more than one trial.
