Why is it important that your body has the ability to replicate your DNA?
Answer:
In order for an organism to grow, develop, and maintain its health, cells must reproduce themselves by dividing to produce two new daughter cells, each with the full complement of DNA as found in the original cell. Billions of new cells are produced in an adult human every day.

Which organism is the primary consumer in the following food chain?
Plant Caterpillar — Lizard Snake
O A. Snake
O B. Caterpillar
O c. Lizard
D. Plant
Lizard organism is the primary consumer in the following food chain
The main consumer is the caterpillar. An organism is a primary consumer if it consumes plants. It qualifies as a secondary or tertiary consumer if it consumes other animals.
What is a primary consumer?
Every food chain starts with producers and here the producers is plant that makes food by the help of the process known as photosynthesis.This process converts the solar energy into chemical energy.
The primary consumer is caterpillar that is dependent on the plants for its energy need. They are most herbivores.
The secondary consumers depend on the primary consumer for their food.

Phospholipid bilayer:
Fibrous Protein:
Pore Protein:
Glycoprotein:
Channel protein:
Answer: -Forms a pone for movement of water -Transports ions -Used for identification of cells -Receptors for the cell -2 layers that limit what enters or leaves the cell
Answer:
Phospholipid bilayer: layers that limit what enters or leaves the cell
Fibrous Protein: Receptors for the cell
Pore Protein: Transports ions
Glycoprotein: Used for identification of cells
Channel protein: Forms a pone for movement of water
Explanation:
Phospholipid bilayer is consist of two layers, interior layer is hydrophilic (water loving) and exterior layer is hydrophobic (water hating). This layer functions as a selectively permeable membrane and allows only required materials into the cell.
Fibrous Protein is one of the type of protein and act as cell surface receptor. for example: collagen and fibronectin act as cell surface.
Pore Protein are beta barrel proteins that creates pores for the ions to diffuse across the cell.
Glycoproteins are located on the surface of the lipid bilayer and act in cell-cell recognition and bind to the cell after recognizing or identifying properly for further procedure.
A channel protein is a channel in he cell membrane that is made up of amino acids. It forms a hydrophilic gateway for water and small, polar ions.
Hence, the correct answer is:
Phospholipid bilayer: layers that limit what enters or leaves the cell
Fibrous Protein: Receptors for the cell
Pore Protein: Transports ions
Glycoprotein: Used for identification of cells
Channel protein: Forms a pone for movement of water

3.) Cellular respiration
Explanation:
During cellular respiration, the energy stored in glucose is transferred to ATP.
During this, glucose, in the presence of oxygen, is converted into carbon dioxide and water.
glucose + oxygen → carbon dioxide + water.
During this process, the energy stored in glucose is transferred to ATP.

Got 100% <3
The amount of energy that is available to organisms above producers is equal to the gross primary productivity minus the amount of organic material used in respiration (Option D).
Producers (e.g, plants, algae) are all autotrophic organisms at the first trophic level of the food chain in a particular ecosystem.
Gross primary productivity refers to the net amount of carbon fixed by producers in a particular ecosystem.
Moreover, the net primary productivity refers to the net amount of carbon dioxide that is fixed by producers (i.e., organic material) in an ecosystem minus the amount of organic material that is used for metabolic activities, i.e., during cellular respiration.
Therefore, the net primary productivity (NPP) can be estimated as the gross primary productivity (GPP) minus respiration rate (R):
NPP = GPP - RIn conclusion, the amount of energy that is available to organisms above producers is equal to the gross primary productivity minus the amount of organic material used in respiration (Option D).

In each case, what is the end product of burning the fossil fuel, and where does it go?
Answer:
when fossil fuels are burned they release carbon dioxide and other greenhouse gases which traps heat in the atmosphere and making them primary contributors to global warming and climate change
Explanation:
When fossil fuels are burnt, they generally give rise to six different kinds of products, these are carbon dioxide, sulfur dioxide, carbon monoxide, lead, nitrogen oxides, and particulate matter.
• Of these, the main product of the burning of fossil fuels is carbon dioxide.
• When the burning of fossil fuels takes place, the carbon dioxide and other greenhouse gases get released into the atmosphere in excess amounts and trap heat more than expected.
• Thus, making them the primary contributors to climate change and global warming.

Why does the thermosphere have the highest temperature of alle
atmosphere layers?
O A. It has the least gas particles.
B. It is closest to the sun.
C. It contains the ozone layer.
D. It is the thinnest layer.
Answer: B.
Explanation:
The thermosphere is most directly affected by the Sun’s radiation.
The thermosphere have the highest temperature of alle atmosphere layers It is closest to the sun.
What is Thermosphere?A portion of the Earth's atmosphere known as the thermosphere is situated precisely above the mesosphere and under the exosphere. It stretches from around 90 km (56 miles) to 500–1,000 km above the surface of our planet.
In the lower thermosphere temperatures rise dramatically before leveling off and remaining rather constant as altitude rises above that point. The thermosphere's temperature is significantly influenced by solar activity.
In general, the thermosphere is around 200° C hotter during the day than at night, and about 500° C hotter during periods of high solar activity.
Therefore, The thermosphere have the highest temperature of alle atmosphere layers It is closest to the sun.
