Biology
1 answer:
Vlada [557]3 years ago
4 0

Answer:

True.

Explanation:

Earth rotation can be defined as the amount of time taken by planet earth to complete its spinning movement on its axis. This ultimately implies that, the rotation of earth refers to the time taken by earth to rotate once on its axis. One spinning movement of the earth on its axis takes approximately 24 hours to complete with respect to the sun.

Basically, the effect of the Earth spinning on its axis on winds and currents is that, global winds will move along a curved path and therefore cause ocean currents to curve.

As a result of the Earth's rotation on its axis, a phenomenon known as Coriolis effect arises.

Coriolis effect occurs when circulating winds are deflected to the left in the southern hemisphere and to the right in the northern hemisphere.

Hence, rather than have this air circulating in a straight pattern, it is deflected to the left of the southern hemisphere and to the right of the northern hemisphere, typically in a curved path or pattern.

In conclusion, we can say that the deflection of fluids due to the rotation of earth is the Coriolis effect.

Science <br><br> Myth: Tigers and goldfish are not related.
DerKrebs [107]

Answer:

Although they are not closely related, as vertebrate animals, they share some characteristics and belong to the same Phylum.

Explanation:

Tigers and goldfish belong to different Classes. Tigers (<em>Panthera tigris</em>) belong to the Class Mammalia, while goldfish (<em>Carassius auratus</em>) belong to the Class Actinopterygii. However, they both belong to the Phylum Chordata.

Chordates share particular characteristics, such as a dorsal neural tube, a notochord, a bilateral symmetry, circulatory system, amongst other features. They are divided into different groups of vertebrates as well: mammals, birds, amphibians, reptiles, and fish. And, according to evolutionionary studies, over 300 million years ago, the first vertebrates that lived on land (amphibians) evolved from a lobe-finned fish species, which eventually led to the evolution of mammals that adapted to terrestrial environments.

Therefore, even though goldfish and tigers may seem completely different, they share similar characteristics. Plus, they are vertebrates that belong to the same phylum.

Name three evolutionary trends that occurs as organisms become more complex
Alexus [3.1K]

Answer:

divergent, convergent and parallel evolution

Explanation:

The evolution of analogous structures is called convergent evolution which occurs due to different organisms exploiting the same environment. Divergent evolution is basic structural forms of organs with the same embryonic origin are modified to serve different functions because of exploiting different ecological niche. Parallel evolution occurs when two species evolve independently of each other, maintaining the same level of similarity. Parallel evolution usually occurs between unrelated species that do not occupy the same or similar niches in a given habitat.

Histones are essentially identical in sequence/structure in all eukaryotic organisms from yeast to plants to animals. What does
xxTIMURxx [149]

Answer:

It indicates that core histone genes were present in the last common ancestor of yeasts, plants, and animals

Explanation:

Histones are highly basic proteins that can strongly interact with DNA, which is packaged into nucleosomes, the basic structural and functional unit of chromatin. Each nucleosome is composed of approximately 147 base pairs of DNA wrapped around a core of eight histone proteins (two copies of four types of histones H3, H4, H2A, H2B). These core histones are evolutionarily conserved across eukaryotic kingdoms in terms of sequence and structure. Therefore, DNA-packaging into nucleosomes is considered a constraint for the evolution of core histones. Moreover, the presence of conserved core histones in eukaryotic kingdoms (e.g., yeast, plant, and animal kingdoms) is strong evidence that histone-mediated DNA packaging was presumably present in the last common ancestor of eukaryotic genomes.

How would there be flooding in the villages is there is a dam in place?
frosja888 [35]
The dam could burst or, if not properly constructed cause water to spill over the sides and top of the dam. Hope this helps.
