Answer:
Sporozoa-flexing the pellicle
Explanation:
Sporozoa do not have flagella, cilia, or pseudopodia and they show gliding movement, amoeboids show movement by pseudopodia, ciliates by cilia and zooflagellates show by flagella, the pellicle is shown by paramecium.
So, the correct option is 'Sporozoa-flexing the pellicle'.
why is it important photosynthetic organisms to have access to water
Answer:
Plants also need water for photosynthesis. Photosynthesis is what plants do to create their food, and water is critical to this process. ... The water from the leaves evaporates through the stomata, and carbon dioxide enters the stomata, taking the water's place. Plants need this carbon dioxide to make food.

UV radiation exposure causes a mutation in a skin cell that results in the formation of cancer
a chromosomal mutation that affects a sperm cell, deactivating a crucial gene involved in development
an insertion mutation in an egg cell that deactivates a gene for hair color, resulting in a viable error
Answer:
an insertion mutation in an egg cell that deactivates a gene for hair color, resulting in a viable error
Answer:
Option 4. an insertion mutation in an egg cell that deactivates a gene for hair color, resulting in a viable error.
Explanation:
Only germline mutations are hereditary in nature i.e., that can be passed on from the parent to the offspring. Examples of hereditary mutation include Sickle cell anemia or hemophilia.Germline mutation: Any noticeable genetic changes in the germ cells of the body that is passed on from the parent to off spring.Mutations such as somatic cell mutation, chromosomal mutation, silent mutations are not hereditary.Option 4 talks about the mutation in egg cells i.e., the reproductive cell which affects the phenotypic traits such as hair color. The change in the phenotypic trait means that it is a genetic mutation of the egg cell as phenotypic changes only occur as a result of genetic mutation. Hence, any detectible mutation in the germ cell can pass on from a parent to offspring.For more information:

under the biological species concept, what criterion is used to assign populations of organisms to the same biological species?
Answer: According to the biological species concept, organisms belong to the same species if they can interbreed to produce viable, fertile offspring. Species are separated from one another by prezygotic and postzygotic barriers, which prevent mating or the production of viable, fertile offspring. Speciation is the process by which new species form

Two women gave birth to girls in the same hospital at the same time. The nurses think they may have accidentally switched the babies' name tags and given the babies to the wrong parents. One baby, Jane, is type O blood. The other baby, Mary, it type A blood. The father in the first set of parents, the Reds, is blood type A and the mother is blood type B.The father in the second set of parents, the Greens, is blood type AB and the mother is blood type O.Which baby belongs to the Reds?
Answer:
Jane belongs to the greens
Mary belongs to the Reds
Mary belongs to Greens, whereas Jane belongs to Reds (it is due to the allele in the parents).
What is the ABO blood system?The blood system is an allele system that determines the presence of antigens in the red blood cells.
In the ABO blood system, the A and B alleles are codominant, whereas the O allele is recessive and masked by A and B.Mary is type A blood, whereas Jane is type O blood which can be due to the following allele combinations:Reds
A O
B AB OB
O OA OO
Greens
A B
O AO OB
O AO OB
In conclusion, Mary belongs to Greens, whereas Jane belongs to Reds (it is due to the allele in the parents).

A) formation from weathering of rocks
B) organic content, including microbes
C) pore spaces allowing the flow of water
D high surface area increasing oxidation
The characteristic of soil that makes it the largest pool of carbon is its organic content, including microbes.
Soil is defined as the outermost portion of the earth's crust on which plants grow. The soil is the part of the earth that supports plant growth because it is rich in nutrients and organic matter.
Plants and animals die and decompose. The carbon content of these organisms are thereby returned to the soil. Also, many microbes are found in soil. Therefore, the characteristic of soil that makes it the largest pool of carbon is its organic content, including microbes.
