Answer:

1.reduced oxygen levels

4.blocked blood vessels

3.heart disease

Explanation:

Sickle cell anemia is a disease that causes changes in the shape of red blood cells. These globules are responsible for the oxygenation of tissues, when a person has sickle cell anemia, these globules have an incorrect structure, lose their rounded and elastic shape, assume a plump appearance and become hardened. This prevents the red blood cells from being able to couple with the oxygen molecules.

As a result of this, people like this disease have problems such as: blockage of blood flow and lack of oxygenation in the tissues, joint pain, intense fatigue, pallor, delayed growth, wounds, gallstones, neurological, cardiovascular, pulmonary and kidney problems.

Describe what happens as a plant's turgor pressure increases and decrease AS MUCH POINTS AS I CAN GIVE​
Dimas [21]

Answer:

Brainliest pls

Explanation:

Turgor pressure in plants. Turgor pressure within cells is regulated by osmosis and this also causes the cell wall to expand during growth. Along with size, rigidity of the cell is also caused by turgor pressure; a lower pressure results in a wilted cell or plant structure (i.e. leaf, stalk).

Turgor pressure in plants plays a key role in processes such as growth, development, mechanical support, signalling, flowering and stress response. Turgor pressure is an ideal means in plant cells through which the energy content of water molecules (water potential) can be adjusted quickly, within seconds.

What evidence do paleobotanists look for that indicates the movement of plants from water to land?
attashe74 [19]

The evidence that paleobotanists look for that indicates the movement of plants from water to land is the possession of waxy cuticle to decrease evaporation from leaves.

<h3>What are some adaptations of plants on land compared to water?</h3>

Plants possess various adaptive features which enables them to survive on land or in water.

Plants that are found in water are known as aquatic plants. They possess features which enable them to get rid of excess water as well as to stay afloat on water. For example, their leaves are waxy to enable them remain afloat.

Plants found on land are terrestrial plants and possess features that enable them survive on land. They possess features which prevent excessive water loss such as waxy cuticle.

Therefore, the evidence that paleobotanists look for that indicates the movement of plants from water to land is the possession of waxy cuticle to decrease evaporation from leaves.

In conclusion, plants show adaptations as they moved from water to land.
