Cells need oxygen and nutrients to function well and get rid of waste products produced incellular reactions. Which system participates in these exchanges?

Answers

Answer 1

Answer:

cardiovascular system

Answer 2

Answer:

circulatory system

A requirement for the circulatory system to carry out its function of bringing blood close to cells so that the exchange of nutrients (e.g., oxygen) and wastes can take place by diffusion is that the blood be able to flow through the complicated networks of blood vessels in the various organs

Kai has a see-through glass tank with air, plants, and animals that eat
those plants. He sealed the tank so no material can get into or out of it,
but light can get in when the tank is not covered.
The light for the tank has been on all day, and Kai measured the carbon
in the air and found that it is decreasing. How is carbon moving between
the air and the living things in
the tank? What is happening to the amount
of carbon in living things?
Just tell me those two questions plz help me I will give you my points I swear plz help me I beg you

Answers

Simple answer is that the plants are conducting more photosynthesis than all the organisms in the tank are carrying out cellular respiration. This would be why the carbon (CO2) levels are decreasing. They are being incorporated into the plant as sugars.

The amount of carbon is captured by plants to perform photosynthesis as a light for the tank has been on all day and prepare their own food. The product of photosynthesis is consumed by other organisms to perform cellular respiration.

What are the components of photosynthesis?

The components of photosynthesis may include carbon dioxide, water, and sunlight as raw materials to convert into glucose (a food molecule).

The amount of carbon will not remain the same for the entire time in the living organism. The cycling of carbon is processed synergistically during photosynthesis and cellular respiration.

Living things in the tank respire out carbon, which is taken up by plants for photosynthesis, a product of photosynthesis are the reactants for cellular respiration. In this way, carbon delocalized among the living entities.

Therefore, it is well described above.

In the 1970s, the pesticide DDT was used to kill insects that damaged fruit and vegetable crops. Most insects died from being exposed to DDT, but some survived. These surviving insects contributed to an increase in their population by

Answers

Answer:

gaining modification in their Gene's which helped them to resist that particular pesticide

These surviving insects contributed to an increase in their population by passing genes for DDT resistance to the next generation.

What is a resistance gene?

In order to survive, bacteria can create mechanisms known as resistance against antibiotics and antifungals. The germ's resistance mechanisms are determined by the specific proteins that DNA instructs the germ to produce. Many different forms of resistance genes can be found in bacteria and fungi.

Once a bacteria have acquired a resistance gene and incorporated it into its DNA, the bacterium can dominate other bacteria and convey the resistance gene to all of its offspring. Bacteria reproduce quickly, which amplifies resistance.

Hence, These surviving insects contributed to an increase in their population by passing genes for DDT resistance to the next generation.

Why is it possible that two ecosystems with identical conditions of temperature and precipitation, could support different plants?

Answers

Answer:

Because even if they are similar, they still have a difference between them, and that difference helps other plants.

It is possible because plants require other factors like sunlight and soil nutrients) other than Temperature and precipitation to grow

Plants require some Important factors for its growth and development and they are :

Temperature precipitation Sunlight soil nutrients type of soil

The two ecosystems with identical conditions of Temperature and precipitation might have differences in the amount of sunlight they receive and the Nutrients contained in its soil. therefore the ecosystems although similar can support different plants based on the difference in the amount of sunlight and Nutrients contained in the soil.

The Haunted Forest  

Once upon a time there was a family, made up of two young ones and their parents, traveling by road to road. One day the car broke down in the forest. The parents went out to get help, and so the children would not get bored, they left them with the radio on. It turned night time and the parents still did not return. Then suddenly they heard the disturbing news go on in the radio: A very dangerous killer had escaped from a prison near the forest. Hours passed and the children's parents did not come back. Suddenly, they began to hear something really loud. ¨Bang, Bang, Bang¨. They heard that which seemed to come from something hitting the top of the car. Then, the sound became louder and louder every time. ¨BANG, BANG, BANG¨. The terrified children could no longer resist. They opened the door and ran in a hurry. Only the eldest of the children dared to turn his head to see what caused the loud noise. He should have not done it though, there was a large and scary man on top of the car, who hit the top of the vehicle with something on his hands, they were the heads of his parents! The children began to run even faster and the large man began to run towards them. The children ran into the forest and so did the large man.
