why do x-linked conditions appear more frequently in males than in females?
Answer:
Because, with females, who have two x-chromosomes, meaning both parents (mother and father) have to pass down alleles for the condition, and males only need one parent (mother) to pass down the condition for the male to have the mutation
X-linked conditions appear more frequently in males than in females because:-
In males there is only one X chromosome.Any X linked condition will appear in males as there will no other X chromosome to dominate it.In female there are two X- chromosome. If any one of the two X chromosome has defect other chromosome will dominant it and will the female will act as a carrier.What are X linked disorder?X-linked disorders are caused by variants in genes on the X chromosome, one of the two sex chromosomes in each cell. In males who have only one X chromosome, an alteration in the only copy of the gene in each cell is sufficient to cause the condition.

Answer: C.-Water
Explanation: Water is the main component when it comes to wetlands.
Habitat is the environmental place where organisms like plant and animal lives. Water is the habitat component present in the wetland ecosystem. Thus, option C is correct.
What is an ecosystem?An ecosystem is a biological community that lives together and has an interconnection with each other as well as their surroundings and other abiotic factors.
The ecosystem can be found in freshwater, marine, or terrestrial places. The wetland ecosystem is covered by water in all seasons and is seen in the form of swamps, marshes, etc.
The wetland is characterized by the presence of water that controls the erosion, water quality, abatement of the flood, etc.
Therefore, water is a component of the wetland ecosystem.

Explain how water move from cell to cell in a leaf
Answer:
By osmosis, water enters the root and travels through the root cells until it reaches the xylem vessels. These canals carry water from the stem to the leaf. Transpiration is the process of removing water from the leaves of plants via evaporation.
Explanation:
Water moves from cell to cell in a leaf through a process called transpiration, facilitated by a combination of cohesion, adhesion, and capillary action in the plant's vascular system.
Transpiration: Transpiration is the process by which water vapor exits the leaf's stomata (tiny openings on the leaf surface) into the surrounding atmosphere. As water vapor evaporates from the cells within the leaf, it creates a lower pressure within the leaf's interior, drawing water molecules from neighboring cells.
Cohesion refers to the attraction between water molecules, causing them to stick together. Adhesion, on the other hand, is the attraction between water molecules and the surfaces of other materials, such as the walls of plant cells and the walls of xylem vessels. These properties work together to create a continuous column of water within the plant's vascular system, allowing water to move upward from the roots to the leaves.
