His space station has plants growing inside it, and astronauts who eat the fruits and vegetables from those plants. Because it i

s in space, the station is sealed so no material can get in or out. The space station is in Earth’s shadow, so no light is getting into it. The sensors in the space station show that carbon dioxide in the air is increasing.What is happening to the energy storage molecules in the plants and humans in the space station? Explain your answer as completely as possible.

Answer:

Photosynthesis is not taking place and carbon dioxide is not being processed.

Explanation:

The process by which plants make glucose (carbohydrates = energy stores) from carbon dioxide and water is called photosynthesis and uses sunlight energy. A by-product of photosynthesis is oxygen.So plants use water and sunlight to grow and they produce oxygen. Animals on the other hand eat plants, use oxygen and breathe out carbon dioxide.

Since the space station is in the shadow of the earth, the plants are unable to complete the process of photosynthesis and the carbon dioxide that is being produced by the humans cannot be utilized by the plants due to no sunlight. There for the carbon dioxide is going to continue to build up as the energy storage molecules are being depleted and not replenished.

If a homozygous black bull is mated with a homozygous white cow and the calf is gray, this could be an example of ___________. H
givi [52]

Answer:

Incomplete dominance

Co-dominance

Explanation:

Gregor Mendel discovered the principles that governs heredity, in which one of them is that an allele called DOMINANT allele, is capable of masking the expression of its variant allele called RECESSIVE allele in a heterozygous state. However, there has been genetic scenarios contrary to this his LAW OF DOMINANCE.

One of those Non-mendelian pattern of inheritance is a phenomenon called INCOMPLETE DOMINANCE, where an allele does not mask the expression of another completely, instead their combined state produces a third intermediate phenotype that is different from both parents. This is the case of the homozygous black bull mated with a homozygous white cow to produce a grey calf. The grey phenotype is an intermediate phenotype of both the black and white colours that forms due to incomplete dominance.

Another genetic scenario is called CO-DOMINANCE, where one allele is neither dominant nor recessive to the other allele, but instead both phenotypes becomes simultaneously expressed in the heterozygous offspring. In this case, the black bull and white cow were mated to form a heterozygous calf with both black and white spots.

If sugar is sprinkled on a strawberry, osmosis will cause
Goshia [24]

Answer:

The correct answer is c. water to move out of the strawberry, making it smaller

Explanation:

Osmosis is the process refers to the movement of liquid molecule from the area of high solute concentration to an area of low solute concentration through a semipermeable membrane to equalize the osmotic balance.

Osmosis is important for any cell to maintain a proper osmotic balance of the cell. So if sugar is sprinkled on a strawberry the solute concentration outside the strawberry cells will increase which will result in water release from the cell.

This release of water from the cell will shrink the strawberry and make it small.  Therefore the correct answer is c.

Silver chloride combines with Copper (II) fluoride to yield Silver fluoride and Copper (II) chloride.
MA_775_DIABLO [31]
<h3>Answer;</h3>

2, 1, 2, 1

<h3><u>Explanation</u>;</h3>

Silver chloride reacts with Copper (II) fluoride to form Silver fluoride and Copper (II) chloride.

AgCl (aq) + CuF2 (aq) ----> AgF (s) + CuCl2 (aq)

The balanced chemical equation will be;

2AgCl (aq) + CuF2 (aq) ----> 2AgF (s) + CuCl2 (aq)

Balancing a chemical equation ensures that the Law of conservation of mass is conserved , such that the number of atoms of each element on either side of the equation is equal.
