Explanation:

If a cell's mitochondria were destroyed it would die. Mitochondria are the power houses of the cell and without energy, necessary reactions could not take place .

If a mitochondria stopped working the cell would not have its respiratory function such as to use carbon dioxide, water, and energy in which the cell needs to survive so the cell would eventually stop moving and slowly die out with no nutrients and energy.

Answer:

This question lacks options, the options are:

A). Active transport requires chemical energy to move nutrients from areas of low concentration to areas of high concentration.

B). Passive transport requires chemical energy to move nutrients from areas of low concentration to areas of high concentration.

C). Active transport moves nutrients from areas of high concentration to areas of low concentration without the use of chemical energy.

D). Passive transport moves nutrients from areas of low concentration to areas of high concentration without the use of chemical energy.

The answer is A

Explanation:

Transport of materials across a cell occurs via passive transport or active transport depending on whether energy input is required or not to facilitate the movement.

- Passive transport is the transport of materials e.g nutrients from areas of high concentration to areas of low concentration i.e down a concentration gradient, without the use of chemical energy (ATP).

- On the other hand, active transport requires chemical energy (ATP) to move nutrients from areas of low concentration to areas of high concentration i.e against concentration gradient.

Answer:

The atria are thin-walled sacs that receive blood from the body or lungs, while the ventricles have a thick muscular wall because they must pump the blood with greater pressure than the atria.

Explanation:

In the human heart, the atria and ventricles are responsible for handling blood and have different structures and function.

The structure of each chamber of the heart is configured to be able to fulfill the specific function that they possess.

Answer:

The solar system speed and Milky Way speed should be switched.

Explanation:

The speed of the Earth is with respect to how it moves around it's own axis (rotation speed), the Sun (revolution speed), solar system (solar system speed), and the milky way galaxies (milky way speed) etc.

According to this question, Luca made a chart for this Earth's four basic movements. The chart with their respective speed are as follows:

Rotation Speed - 0.3 miles/sec

Revolution Speed - 18.5 miles/sec

Solar System Speed - 370 miles/sec

Milky Way Speed - 150 miles/sec

Luca, however, made a mistake in his chart.

- The rotation speed of the Earth around its axis is correctly 0.3miles/sec

- The revolution speed of the Earth around the sun is correctly 18.5 miles/sec

- The solar system speed of the Earth i.e. around the solar system is about 150miles/hour

- The milky way speed of the Earth i.e. around local group of galaxies is about 370miles/hour.

Based on the comparison of Luca's chart and correct speed illustration, THE SOLAR SYSTEM SPEED AND MILKY WAY SPEED SHOULD BE SWITCHED.

Answer:

Because eggs contain amost all organelles, and materials for growth. A sperm only contains haploid chromosome and certian mitochondria for movement.

Explanation:

:)

The egg, like a sperm cell, has a nucleus with half the number of chromosomes as other body cells. Apart from a sperm cell, the egg contains a large amount of cytoplasm, or cell contents, which is why it is so large.

A gamete is an animal or plant reproductive cell. Female gametes are known as ova or egg cells in animals, while male gametes are known as sperm.

Ova and sperm are haploid cells, with only one copy of each chromosome in each cell. A sperm and an ovum combine during fertilization to form a new diploid organism.

Because the formation of the egg begins before birth inside the developing body of a female embryo and is not completed until the egg is fertilized by a sperm many years later, the egg cell is much larger than the sperm cell.

The sperm cell is small in size because its primary function is to swim to the egg cell.

Thus, the egg cells are large and sperm cells are small.

Answer:

Some bacteria are good for you, including the bacteria in your digestive system, or gut. These bacteria help to break down food and keep you healthy. Other good bacteria can produce oxygen are used to create antibiotics. Bacteria are used in food production to make yogurt and fermented foods.

An example of how Eubacteria can be beneficial is that these bacteria fix nitrogen for soil that can be used by living beings.

The bacteria in your gut and digestive tract are among the beneficial bacteria. These microorganisms aid in the digestion of food and promote good health. To make antibiotics, other beneficial microorganisms that can also produce oxygen are employed. Yogurt and other fermented foods are produced using bacteria in the food industry.

Oxygen, carbon, nitrogen, and phosphorus that living things like animals and plants cannot use can be converted by eubacteria into usable forms. In the soil, they fix the nitrogen that is present in the air.

Therefore,  Eubacteria can help the environment by fixing nitrogen into the soil so that living things can use it.

The question is incomplete, the complete question is;

In the process of photosynthesis, plants use carbon dioxide (CO2), water (H2O), and light energy to produce a sugar (C6H12O6) and oxygen (O2). In the process of aerobic cellular respiration, animals and plants release energy from sugar and oxygen and produce carbon dioxide and water. The chemical equations that describe these reactions look like this:

photosynthesis: 6CO2 + 6H2O + light ---> C6H12O6 + 6O2

cellular respiration: C6H12O6 + 6O2 ----> 6CO2 + 6H2O + 36 ATP

How do these equations explain why the total amount of O2 and CO2 remains the same?

Answer:

See explanation

Explanation:

If we look at photosynthesis and cellular respiration, we will realize that the both are complementary processes. The product of one process is the input material for the other process.

Respiration and cellular respiration helps to balance the amount of O2 and CO2 in nature because photosynthesis takes in CO2 and releases oxygen while cellular respiration takes in oxygen and releases CO2. This maintains the delicate balance between the both gases in nature.
