Correct answer: B). With fewer contractions

The main function of a contractile vacuole is to maintain the sufficient amount of water in the protoplasm of the cell. For the freshwater amoeba contractile vacuole is needed to pump water and maintain a osmoregulation.

But when it is kept in sea water, more contraction is required to expel the water out of the cell in order to make the environment inside amoeba same as of sea water.

Answer:D

Explanation: Because it has the least amount of density in it. All the others are heavier, meaning they will sink. Just like if you drop a rock water and a feather, the feather will float.

Density def:

Density, mass of a unit volume of a material substance. ... Density offers a convenient means of obtaining the mass of a body from its volume or vice versa; the mass is equal to the volume multiplied by the density (M = Vd), while the volume is equal to the mass divided by the density (V = M/d).

All weather is energy in motion. Where does this energy come from?

icang [17]

Answer:

Energy makes it all happen. The Sun radiates huge amounts of energy. Only a small portion of that energy hits the Earth, but it is enough to light our days, heat our air and land, and create weather systems over the oceans. Most of the energy you will learn about comes from the Sun.

In horses, the allele for a black coat (B) is dominant over the allele for a brown coat (b). A cross between a black horse and a

GaryK [48]

Answer:

Bb X bb

Explanation:

It is given that the allele B for the black coat is dominant over allele b for a brown coat.

A dominant allele always leads to the expression of the dominant trait in the heterozygous condition.

When a black and brown horse is crossed as given in the question and the result is a brown foal, then the genotype of the brown foal must be bb as the brown coat is a recessive trait.

Since each parent contributes one allele each for a given gene, the black horse must have b allele, and hence must be heterozygous Bb.
The cross is shown in the punnett square.
