The hypothesis that whales evolved from land-dwelling ancestors is supported by __________. ANSWER Unselected molecular comparisons of whales and fish Unselected historical accounts of walking whales Unselected the ability of captive whales to be trained to walk Unselected fossils of extinct whales that had increasingly reduced hind limbs Unselected evidence from the current biogeographic distribution of whales Unselected I DON'T KNOW YET

Answers

Answer 1

Answer:

The answer is "Third choice".

Explanation:

Fossils are a great source of evidence about whales' forebears. It demonstrates, for instance, that a land mammal lived 50 million to 700 years ago. Whales evolved from such marine residents were thought by scientists. Scientists. This and more cells from a fossil can be said, so the concept that whales evolved from ancestors of land is reinforced by an extinct whale which has shortened the hind limbs evermore.

How long does it take the moon to rotate on its axis?


about 25.3 days


about 27.3 days


about 30 days


about 2 months

Answers

Answer:

27.3 days

Explanation:

The Moon takes 27.3 days to rotate on its axis as the Moon takes 29.5 days to revolve around the Earth. So, the correct option is B.

What is Rotation?

Rotation is defined as the circular movement of an object around a central axis where a two-dimensional rotating object has only one possible central axis and can rotate in a clockwise or counterclockwise direction, while a three-dimensional object has an infinite number of possible centers that is axes and rotational directions.

The Moon orbits the Earth in the same direction, completing one orbit relative to the vernal equinox and the stars in about 27.32 days while one orbit relative to the Sun takes about 29.53 days.

Thus, the Moon takes 27.3 days to rotate on its axis. So, the correct option is B.

how meiosis turn one cell into four new sex cells?

Answers

Answer:

A single round of DNA replication occurs in the parent cell, followed by two distinct nuclear division cycles. The process produces four haploid daughter cells, each with half as many chromosomes as the diploid parent cell.

Explanation:

During sexual reproduction, meiosis produces the sex cells that combine to make new children.

Meiosis is a type of cell division that results in the formation of sex cells (egg and sperm). And that is brought together to generate new progeny through the act of sexual reproduction.

Meiosis generally results in 4 haploid daughter cells, meaning half no chromosomes are contained in diploid cells.

When water warms or cools, ____ either break or form.
Thus, water absorbs or releases a great deal of ____, helping to moderate temperatures.
Water is a versatile ____.
Blood and other biological fluids are aqueous solutions with a diversity of dissolved ______.

Answers

Answer:

The polarity of water molecules and the hydrogen bonds between water molecules explain most of water's life-supporting properties.

The cohesion of water molecules to each other helps transport water from the roots to the leaves on plants.

When water warms or cools, hydrogen bonds either break or form.

Thus, water absorbs or releases a great deal of heat, helping to moderate temperatures.

Water is a versatile solvent.

Blood and other biological fluids are aqueous solutions with a diversity of dissolved solutes.

Explanation:

The sentences presented in the question above had their various spaces complemented by the words that best fit the sentence and that were capable of forming true invormations on water.

Water is a very versatile solvent as it is capable of dissolving and mixing with various substances both liquid and solid. Furthermore, water has a great capacity to absorb or release heat, which is very useful for the entire planet, as this allows water to be very efficient in regulating temperature.

Water is formed by H2O molecules, which hold these molecules together are the hydrogen bridges formed between them. Hydrogen bridges are broken through heat, which allows the water to evaporate, but at low temperatures these bridges are strengthened and new bridges can be created, which allows the water to become solid.

The properties of water are extremely important for life on the planet and for most biological processes we know about. Among these properties we can mention polarity and cohesion as one of the most important. Polarity allows water to be a polar substance, while cohesion allows water to create an attractive relationship between molecules.
