Answer: D I think

Explanation:

Before 1945, the US and USSR worked well together mainly because cooperation was necessary to fight common enemies, Germany and Japan, during World War II. Thus, correct option is D.

In order to fight Nazi Germany and Imperial Japan, the US and USSR forged an alliance during World War II. The two nations momentarily put their ideological differences aside to concentrate on the shared threat, which is how the partnership came about. During this time, both countries provided one another with military assistance and basic resources.

It is crucial to remember that the alliance began to deteriorate following the war as conflicts developed between the capitalist US and the communist Soviet Union. The Cold War, which was defined by rivalry and mistrust between the two superpowers during the post-war period, heralded a substantial change in their earlier cooperative relationship.

Shrimp

Pleopods or swimmerets are the names of the appendages, which are utilised for activities other than swimming. Others contain gills for breathing, while other species of shrimp utilise the first pair or two for insemination. Some shrimp species use them for brooding eggs.

The thorax and the head are the two halves of their bodies. The two halves are joined by a small abdomen and the cephalothorax. The carapace, which serves as the body's physical defence, is a tough covering. Together with its gills, the shrimp's mouth functions.

The gills let it to obtain oxygen from the surrounding waters while being protected by the hard external shell. Its strong shell also sprouts its legs, eyes, and rostrum. Shrimp have a pointed beak or snout, known as the rostrum, that protrudes from the top of their bodies to defend them from predators. Additionally, this beak acts as a stabiliser when swimming backwards and forwards.

Two organisms in the Genus Homo would indicate the closest relationship.

The extant species Homo sapiens (modern humans) and several extinct species categorized as either ancestral to or closely related to modern humans (depending on the species) are all included in the otherwise extinct genus Australopithecus, where the species Homo first appeared.

The most notable of these extinct species are Homo erectus and Homo neanderthalensis. The first individual of the genus, Homo habilis, emerged just over 2 million years ago. Homo, along with the genus Paranthropus, is most likely related to Australopithecus africanus, which had previously diverged from the Pan, or chimpanzee, branch.

The scientific name of the genus Homo implies that its constituent species can be categorised as humans. Furthermore, over the course of the 20th century, fossil discoveries of early human and pre-human creatures from the late Miocene and early Pliocene produced a diverse range for classification debates.

In this question, the amount of water absorbed by an egg completely depends on the amount of sugar in which it placed. The amount of sugar stands alone and cannot be altered by other variables hence it is classified as an independent variable.

While the amount of water they absorbed can not stands alone and would be altered by variable like the amount of sugar. Hence, it is classified as the dependent variable.

Therefore, in this example, the different amount of sugar is categorized under the independent variable while the amount of water gets absorbed is categorized under the dependent variable.

Long-term use of one drug increases tolerance to different drugs because these compounds need to bind the same receptors for to produce a given effect.

The expression drug tolerance makes reference to higher concentrations of drugs required to produce the same effect due to the rate between a drug and its receptors in the cell.

This phenomenon (drug tolerance) is associated with the increase of the concentration of a given drug to produce the same effect due to the ligand-receptor relationships between both variables.

Different drugs use the same receptors in the cell to bind and trigger a given signaling pathway, thereby one drug may increase the tolerance of another substance.  

In conclusion, long-term use of one drug increases tolerance to different drugs because these compounds need to bind the same receptors for to produce a given effect.

It's generally recommended that people consume between 45-65% of their total calories in the form of carbohydrates per day. However, carbohydrate needs depend on many factors, including body size, activity levels, and blood sugar control.

Explanation:

PbSO4 has 1 atom of Pb, 1 atom of S, and 4 atoms of O. So, in total it has 6 atoms.

The smallest component that makes up a chemical element is an atom. Atoms that are neutral or ionized are the building blocks of all solids, liquids, gases, and plasma. A normal atom is 100 picometers across, which is incredibly small.

Protons, which have a positive charge, make up the majority of it, while neutrons, which have no charge, form the remainder. All regular, naturally occurring atoms have protons, neutrons, and electrons that orbit them because they are heavy particles.

A sample's mass in grams should be divided by the periodic table's amu atomic mass, and the result should be multiplied by 6.02 x 1023, or Avogadro's number, to determine how many atoms are there. So, PbSO4 has 1 atom of Pb, 1 atom of S, and 4 atoms of O. So, in total it has 6 atoms.

Explanation:

Answer:

Observed light shifts to a longer wavelength.

They indicate receding galaxies.

The light source and observer move farther apart.

Explanation:

Red light is the lowest frequency visible light, violet is the highest frequency (hence INFRA-red, as in below red and ULTRA-violet, as in above violet).

Redshift is an effect where we observe light (from space) that we'd otherwise expect to be higher frequency than observed.

Redshift is an effect very similar to Doppler's effect, where we hear lower (lower frequency) sounds when moving away from a sound source.

Because we're moving away from the light source (or the light source moves away from us). Similarily, when you're driving, you'll pass more cars going the opposite way than those going along with you.

So, when a galaxy recedes (and fast!) we'll observe the light frequency to be lower than the galaxy actually emits. Lower frequency = higher wavelength.

To conclude - any answer that relates to the light being lower frequency, or higher wavelength, or the observer and source moving apart are good answers, whereas those that suggest the opposite are bad answers.
