Q: A cell with two sets of chromosomes is called a? Read this paragraph and choose the correct option from the provided answers: A cell with two sets of chromosomes is diploid , referred to as 2n , where n is the number of sets of chromosomes. Most of the cells in a human body are diploid. A cell with one set of chromosomes, such as a gamete, is haploid , referred to as n . Sex cells are haploid. When a haploid sperm ( n ) and a haploid egg ( n ) combine, a diploid zygote will be formed ( 2n ). In short, when a diploid zygote is formed, half of the DNA comes from each parent. Choices: - haploid - chloroplasts - biploid - diploid A:
(Answer)
diploid

Ques: Q: Where does the christmas tree worm live? Read this paragraph and choose the correct option from the provided answers: It is actually the Yellow Christmas tree worm. These animals are colorful, and can be red, orange, yellow, blue, and white. The Christmas tree worm lives on tropical coral reefs throughout the world. The Christmas tree worm's plumes are used for feeding and respiration. These worms use their plumes to catch plankton and other small particles passing in the water. Cilia then pass the food to the worm's mouth. Choices: - northeast coral reefs - Atlantic shoreline - rainforests - tropical coral reefs A:
Ans: tropical coral reefs

Ques:Q: What is the diffusion of water through a semipermeable membrane according to the concentration gradient of water across the membrane Read this paragraph and choose the correct option from the provided answers: Osmosis Osmosis is the diffusion of water through a semipermeable membrane according to the concentration gradient of water across the membrane. Whereas diffusion transports material across membranes and within cells, osmosis transports only water across a membrane and the membrane limits the diffusion of solutes in the water. Osmosis is a special case of diffusion. Water, like other substances, moves from an area of higher concentration to one of lower concentration. Imagine a beaker with a semipermeable membrane, separating the two sides or halves (Figure 3.21). On both sides of the membrane, the water level is the same, but there are different concentrations on each side of a dissolved substance, or solute, that cannot cross the membrane. If the volume of the water is the same, but the concentrations of solute are different, then there are also different concentrations of water, the solvent, on either side of the membrane. Choices: - nutrients - mirrors - Gravity - osmosis A:

Ans:
osmosis
