Answer: Option D.

The atoms and molecules of the liquid water are moving, and the atoms and molecules of the

table are not moving.

Explanation:

The atoms and molecules of the liquid water are moving, and the atoms and molecules of the table are not moving and this is because the atoms and molecules of liquid water are closely packed together and they collide to each other often, thereby moving in random motion in all directions.

The molecules of solid cannot move because they are closely packed together and there is a very strong of attraction which make them to only vibrate and not move and this make solid to have definite shape.

In pea plants, yellow (Y) seed color is a dominant trait, and green seed color (y) is a recessive trait. Which resulting plant w

german

Answer: The correct answer is-

B. Yy

As per the information in the question, yellow (depicted by Y allele) seed color is a dominant trait whereas green seed color is a recessive trait ( depicted by y allele).

A dominant trait always masks the expression of a recessive trait.

Presence of single dominant allele ( such as in Yy, which shows heterozygous dominant genotype) in the genotype can produce a dominant trait whereas recessive trait is only expressed when its genotype is homozygous recessive (such as yy that is both alleles should be recessive allele) .

A plant with genotype Yy will form two gametes that is Y and y.

When such plants are allowed to interbreed, there is a probability of 25% of producing green seeds in the next generation.

Which word equation summarizes the hydrolysis of a carbohydrate?

maria [59]

Answer: Option C) sucrose + water-glucose + fructose

Explanation:

Sucrose, is a dissacharide (carbohydrate with two simple sugars) composed of glucose and fructose units. Thus, on hydrolysis (addition of water to split a compound) sucrose yields its constituent units.

Thus, the correct answer is that adding water to sucrose splits it into glucose and fructose

In a certain species of plant, the allele to produce green melons (G) is dominant over the allele to produce yellow melons (g).

marishachu [46]

Answer:

4.26

Explanation:

Let the green-melon parents be Gg, then we expect the cross with the yellow-melon plant gg so as to produce 50% Gg and other 50% of gg offspring. What we observed was that 53 green and a 41 yellow. Based on the total number of 94 offspring , we expected half and a half ratios to be 47 of each color.

Observed(o) Expected(e) (o-e) $(o-e)^2$ $(o-e)^2/e$

Green-melon plant 53 47 6 36 0.766

Yellow-melon plant 41 47 -6 36 0.766

Therefore the chi-square value is 1.53 which is less than the critical value of 3.84. Therefore, the null hypothesis is accepted.

A certain area received a large amount of rain and some of it remained on top of the soil. What happened to the rest of this wat

ValentinkaMS [17]

In the large rainfall is some water remains in the top of the soil the rest of this water is seeped into the ground.

<u>Explanation:</u>

Mainly the absorption of water by the ground depends upon the nature and the fertility of the soil.
When the ground receives the water it mainly accounts for the absorption and then there will be a runoff. The absorption helps to raise the level of groundwater for future usage.
The amount of water that can get into the soil mainly depends upon the permeability of the soil surface. The water which can't infiltrate in the soil runs off into the water bodies.
The water is an essential requirement for survival and the existence of biological organisms.
