This is true. The impact of human on trees has been completely negative. This includes deforestation which causing negative effects on the environment. A massive scale of Earth’s forest has been cleared through deforestation. This results to the damage of the land quality.
Answer:
(E) present the two sides of the debate concerning the development of the vertebrate skeleton
Explanation:
In the paragraph, the author talks about two sides of view in the subject of vertebrates evolution. On one hand, he/she says that the first idea of vertebrates development is that the skeleton evolved as a defensive character and that many researchers rely on soft-bodied vertebrates to conclude it. On the other hand, he/she says that other researchers postulate that some vertebrate features (as paired eyes and adaptation in some muscles) could not have evolved if the first vertebrates were not depredators.
Oxygen and carbon dioxide pass through the plasma membrane by simple diffusion, a process of passive transport that moves these gases down their concentration gradient. Certain other substances rely on facilitated transport, another type of passive transport, to cross the membrane.
Oxygen and carbon dioxide pass through the plasma membrane by simple diffusion. The structure of the lipid bilayer, composed of hydrophobic phospholipids, allows small, uncharged molecules such as oxygen and carbon dioxide to diffuse down their concentration gradient. This process is a form of passive transport, meaning it doesn't require energy input from the cell.
When there is a higher concentration of oxygen or carbon dioxide outside the cell than inside, these gases will naturally diffuse across the membrane, moving from an area of higher concentration to an area of lower concentration. The same concept applies when there's a higher concentration of these gases inside the cell; they will diffuse out of the cell into the extracellular fluid where their concentration is lower.
Also note that some polar substances and other molecules that do not easily pass through the membrane rely on facilitated transport. This is another type of passive transport where specific integral proteins or glycoprotein receptors on the cell membrane help these substances cross the membrane down their concentration gradient.

Answer:
Polygenic therapies are more likely to show unintended effects in other regions of the genome likely resulting in harmful diseases.
Explanation:
Gene therapy involves biotechnological techniques that add or remove gene sequences in the genome. These are typically used in eliminating harmful genes that cause genetic diseases or disorders and are generally thought to improve an individual's quality of life.
Polygenic traits are controlled by several genes. Similarly, polygenic diseases may be caused by variations in several gene sequences. These include hypertension, heart disease, and diabetes. Polygenic therapies are more likely to show unintended effects in other regions of the genome, leading to other deleterious disease-causing effects.
Anaerobic respiration
Aerobic respiration
Cellular respiration
Answer:
The correct answer would be photosynthesis.
Photosynthesis is the process by which occurs only in plants and not in animal cells. Rest of the processes can occur in both plants as well as animal cells.
It is the process by which plant cells synthesize their food (glucose) from simple substances such as carbon dioxide and water in presence of chlorophyll and sunlight.
Chlorophyll is an essential element for the process of photosynthesis which is present in plant cells but absent in animal cells.
Photosynthesis does not occur in both plant and animal cells, while anaerobic respiration, aerobic respiration, and cellular respiration occur in both types of cells.
The process that does not occur in both plant and animal cells is photosynthesis. Photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into glucose and oxygen. Animal cells do not have chloroplasts, the organelles required for photosynthesis, so they cannot perform this process.
On the other hand, both plant and animal cells undergo anaerobic respiration and aerobic respiration. Anaerobic respiration occurs in the absence of oxygen and is less efficient than aerobic respiration. Aerobic respiration requires oxygen and is the most efficient way for cells to produce energy.
Cellular respiration refers to the overall process by which cells generate energy from glucose. It includes both anaerobic and aerobic respiration. Therefore, cellular respiration occurs in both plant and animal cells.
