Answer:
A) its elliptical orbit and tilt on its axis
Explanation:
Earth revolves around the sun in an elliptical path. Its axis is tilted to about 23.5° from the vertical.
These two factors determine the global climate on the Earth.
Due to elliptical orbit, the earth is sometimes closer to sun than the rest of the time. When it is closer the global temperature rises by 5 degrees. Due to the tilt of the Earth, seasons occur. The hemisphere which points towards the sun has summers where as which points away has winters.
Thus, the long-term climate change is effected by elliptical orbit and tilt of the axis.
Developed a way to protect their foliage. Instead of flat leaves, pine trees have needles<span>. These </span>needles<span> are the key to the Winter survival of the </span>pine tree<span>. </span>Needles<span> cut evaporation so</span>trees<span> can save water!
Cacti have sines instead of leaves because they help protect them from getting eaten and they don't need leaves because they store water inside themselves.
They both have adapteations to help them servive in very harsh conditions. Cacti use their adaptations to survive in scourching heat and pine trees can servive in freezing cold.</span>
Answer:
The correct answer is A The student is investigating the passive transport of diffusion.
Explanation:
Diffusion is a type of transport process which helps in the transport of small molecules and gases towards their concentration gradient that"s means from region of high concentration to the low concentration region untill equilibrium is reached.
In this question the 10 drops are red coloured food particles that are placed into the beaker, diffuses to all the regions of the beaker untill the concentration of that red colored food particle become same in all the regions to which red colored food particle diffuse.
Folate deficiency impairs DNA synthesis, so the nuclei of immature red blood cells are unable to divide and the cells grow larger than normal. This condition is called macrocytic anemia.
<h3>What is folate deficiency anemia?</h3>
- The red blood cells in folate-deficiency anemia are excessively big. Macrocytes are this type of cell.
- When they are discovered in the bone marrow, they are also known as megaloblasts.
- This anemia is also known as megaloblastic anemia for this reason.
- When your body doesn't get enough folate, it develops a folate deficiency.
- Symptoms include fatigue, weakness, mouth sores, and neurological issues.
- A diet rich in folate-rich foods can help prevent folate insufficiency.
- Haemoglobin, a component of red blood cells, is used to transport oxygen throughout the body.
