Both plant and animal cells need to produce energy for cellular functions. In both types of cell, this function is carried out by the - O Nucleus O Mitochondria O Chloroplast O Vacuoles​

Answers

The answer is mitochondria.

Mitochondria is the “powerhouse” of the cell. Or the “energy source.”

The nucleus is the brain of the cell. It tells everyone else what to do.

Vacuoles store food or water for the organism.

And finally Chloroplast is only found in plants, not animals.

Thus the answer is the MITOCHONDRIA. I hope this helps. Can i get brainlyest??

Tobias found a rock that has a mass of 475kg. He placed it in 2000ml of water and the water rose to 2025ml. What is it’s density?

Answers

Given parameters:

Mass of rock Tobias found  = 475kg

Volume of initial water  = 2000mL

New volume  = 2025mL

Unknown:

Density  = ?

Solution:

Density is the mass per unit volume of a substance.

Mathematically;

               Density  = [tex]\frac{mass}{volume}[/tex]

Volume of rock = New volume - Initial volume = 2025 - 2000 = 25mL

Now let us convert the mass to g;

     1000g  = 1kg

       So; 475kg will be 475000g

So;

  Density of stone = [tex]\frac{475000}{25}[/tex]   = 19000g/mL or 19000g/cm³

Explanation:

                                                     

The spleen and the thymus work together to fight infection. These organs together make up immune system.

What is immune system?

The immune system defends the organism's body against external invaders. Toxins and germs such as bacteria, viruses, and fungi are examples of these (chemicals made by microbes).

The immune system is made up of various organs, cells, and proteins that collaborate.

The thymus and bone marrow, lymph nodes and vessels, spleen, and skin are all vital to the immune system's proper functioning.

The spleen filters and stores blood, as well as producing white blood cells to fight infection or disease.

The thymus gland is located in the upper chest, beneath the breast bone. It is responsible for the maturation of a specific type of white blood cell that fights off foreign organisms.

Thus, immune system encompasses spleen and thymus.

Which best describes the role of chlorophyll in energy conversion?

Answers

Answer:

Explanation:

Chlorophyll absorbs light and converts it to chemical energy. ... During photosynthesis, plants absorb light energy from the sun and convert it into chemical energy in the form of glucose.

The role of chlorophyll during the process of photosynthesis is that it effectively converts the captured radiant energy (light energy) from the sun to chemical energy.

What is Chlorophyll?

Chlorophyll may be defined as the type of green-colored pigment which is present in all green plants, some algae, and cyanobacteria. It is present in the chloroplast of the plant and carries out the entire process of photosynthesis.

This green-colored pigment is generally made up of porphyrin rings with magnesium being the co-factor. A chain of carbon and hydrogen is also present. This is known as the Phytol tail. The function of chlorophyll in each photosynthetic organism remains the same throughout.

Therefore, the role of chlorophyll during the process of photosynthesis is that it effectively converts the captured radiant energy (light energy) from the sun to chemical energy.

Explanation:

Water would be considered an actual renewable resource and actual nonrenewable resource. Thus, option C is correct.

Why water is considered as actual renewable?

Water would be considered an actual renewable. A renewable resource is a resource which can be used repeatedly and replaced naturally. Examples include oxygen, fresh water, solar energy and biomass. New resources may include goods or commodities such as wood, paper and leather.

Non renewable energy comes from sources that will run out or will not be replenished in our lifetimes-or even in many, many lifetimes. Non renewable energy sources are fossil fuels: coal, petroleum, and natural gas.

Potential renewable resource, potential nonrenewable resource, and actual renewable resource and actual nonrenewable resource. Water would be considered an actual renewable.

Therefore, Water would be considered an actual renewable resource and actual nonrenewable resource. Thus, option C is correct.

A cell has many substances and organelles present in it, that all have specific functions in the cell. DNA is the hereditary unit of the cell that contains genetic information about growth, development, and reproduction.

DNA helps in synthesizing protein by a two-step process called protein synthesis. The first step called transcription involves copying the instruction from DNA into an mRNA sequence and the second is producing an aminoacid chain by translating the mRNA sequence.
