C. Beginning of autumn

Explanation:

On this image we can see the position of the Earth toward the Sun in four different parts of the year. WE can see that in one part of the year the Northern Hemisphere is tilted toward the Sun, while in the opposite part of the year it is the Southern Hemisphere that is tilted toward the Sun. In between them, we have 21 March and 23 September when both hemispheres are equally exposed to the sunlight. These to dates mark the beginning of spring and beginning of autumn. As they are dates when both hemispheres receive equal amounts of sunlight, it means that these are the dates when the equinoxes appear on Earth.

Answer:

C. Beginning of autumn

is the position of the Earth that represents an equinox.

Two species that have few physical traits in common do not share a comman ancestor and most likely evolved from different species.

Explanation:

Answer:

C. Water will move into the cell through osmosis. The salt and water concentrations will become similar inside and outside the cell.

Explanation:

Osmosis is the movement of water from its higher concentration to the lower concentration through a semi permeable membrane. Here, the cell have higher salt concentration and lower water concentration as compared to its outside. Since cell membrane is semi permeable, salt cannot pass through it. So, water will move into the cell through osmosis to equalize the salt and water concentration on either side of cell membrane.

Sugars, starches, fats, proteins.

Vegetables and meats are not types of food molecules but rather, specific food molecules.

Final answer:

If everyone on the planet used the same amount of resources as an average American, we would need three planets to support everybody. The U.S. population makes up 5% of the global population but uses one-third of all the resources consumed each year.

Explanation:

If everyone on the planet used the same amount of resources as an average American, we would need three planets to support everybody. The current consumption patterns of humans, particularly in developed countries like the United States, are already dramatically reshaping the world. The U.S. population makes up 5% of the global population but uses one-third of all the resources consumed each year.

- Energy

"Matter is recycled, but energy is not. In an ecosystem, matter is represented by the presence of biogeochemical elements such as Hydrogen, Carbon, Nitrogen, Oxygen, Phosphorus and Sulfur."

In an ecosystem which of these is not recycled energy. Thus, option "B" is correct.

Biodiversity has three levels - ecosystem, species and genetic diversity. Therefore, Biodiversity can be defined as the variability among living organisms involving terrestrial, marine, and other aquatic ecosystems, genes and alleles in a species and their ecological complexes such as diversity within species, and between species of the ecosystems.

Thus, option "B" is correct.

Explanation:

Answer:

C. Positive phototropism

Explanation:

This is a response of plants towards external stimuli. The plant is bent toward the glass of the window because light is coming from the window. It is considered as positive phototropism because it is moving towards the light. The opposite occurs with negative phototropism. In negative phototropism, the movement of plant would be away from the external stimulus.

When you talk about gravitropism, this is the direction of the growth of plants that is affected by gravity. Thigmotropism is the growth response of the plant towards physical touch.  

Answer:

The correct answer is ATP.

Explanation:

When molecules or ions moves into higher concentration from lower concentration through a cell membrane with the help of enzymes and requires energy, this type of transport of molecules or substances called active transport. Active transport requires chemical energy to perform this transport and ATP is the form of chemical energy expended in this process. ATP is an abrevation of adenosine triphosphate.

ATP is the energy expended in active transport.

Active transport is the homeostatic process that requires energy to move particles across the plasma membrane.

Answer:

A prime environmental concern associated with nuclear power is the generation of radioactive wastes like used reactor fuel, uranium mill tailings, and other radioactive wastes. These substances can stay radioactive and threatful to human beings as they remain for thousands of years. These wastes are confined to unique regulations, which manage their transportation, handling, disposal, and storage to safeguard the health of human beings and the environment. The radioactive wastes are categorized as low-level and high-level wastes.

Can you show me the following??

1. False

Whale sharks and manta rays can indeed be large, and they are predators, but they do not pose threat to divers. Both of these species, even though they do not look alike at all, are part of the shark family. While they are both in the predator category, they actually eat miniature organisms and very tiny fish in general, thus not being anywhere near as aggressive or dangerous for the divers as some of their shark relatives. The manta rays for example do not even have teeth to pose a significant threat, they have a poisonous sting on their tail but that is only used for defense, not attack.

2. False

The octopuses are definitely one of the weirdest and most interesting animals on the planet. They are highly intelligent, have even been noticed using tools, have three hearts, one central and eight other independent brains in their tentacles, and also have a beak. Like all of that is not weird enough, they also have the ability to change their color, and not just the color all over, but also to mimic certain patters. The change of color is used for both camouflage for attack and for defense and avoiding predators.

3. True

The turtles spend the majority of their lives in water, but they still use the land for nesting. They will come to the sandy beaches, dig a large hole, and fill the hole with hundreds of tiny eggs, and than cover them with send. The sex of the turtles that are developing in the eggs depends directly on the temperature of the sand, so it can literary be a situation where all of them will be female because of the temperature, or all of them to be male because of the same reason.

4. True

The corals are a weird bunch. They look like plants, but they are actually animals. They also look like one compact unit, but they are actually millions, or billions miniature animals that are collaborating and build colonies. They also are interesting in their reproduction, as all of the species are able to reproduce asexually, but there are some that are able to reproduce both asexually and sexually, depending on the circumstances.

5. Yes.. In turner syndrome every cell of body contains only 45 chromosomes

(44 + X0)..it is monosomy.

It happened when abnormal 22 +0 male sperm fuses with normal 22 +X female.

Or when abnormal female ovum fuses with normal sperm.

The Zygote if formed has 1 copy missing of X chromosomes.. When this zygote undergoes goes mitosis every cell will only 1 coly of X chromosomes.

6. No.. Bcoz in down syndrome.. There is extra copy of chromosome no. 21..

(45 +XX) or (45+XY). No.. They can't give rise to normal child.

Also

Males having down syndrome have very rare chances of being fertile.

7.yes..in case of XXYY syndrome.

In this abnormal male gametes (22+YY) fuses with abnormal female gametes

22+XX.

8. Color blindness is reccessive sex linked disease..

In females there are two copies of X.. Nit present in males and girls having Turner's syndrome.

This type of circulatory system is called the open circulatory system... :)

Answer: Single loop

Explanation:

The circulatory system of the fishes are considered as the single loop circulatory system because they have a single circulatory pattern.

Deoxygenated blood from the body reaches the heart which is then pushed towards the gills. The gaseous exchange takes place between the outer environment and gills and then oxygenated blood is circulated through out the body.
