Describe how The Carbon Cycle works.

1 answer:

4 0

Carbon cycle refers to an array of procedures by which the compounds of carbon are interconverted in the environment, comprising the inclusion of carbon dioxide into living tissue by the process of photosynthesis and then getting back into the atmosphere via respiration, the burning of fossil fuels, and the decomposition of dead organisms.

The following are the steps that illustrate how the carbon cycle functions:

1. Carbon enters the atmosphere as carbon dioxide from combustion and respiration.

2. The absorption of carbon dioxide takes place by the producers to manufacture glucose in photosynthesis.

3. The animals feed on the plant passing the carbon components through the food chain. The majority of the consumed carbon is exhaled in the form of CO2, which was produced at the time of aerobic respiration. The plants and animals die eventually.

4. The dead plants and animals get dissociated by the dead organisms and return the carbon present in their bodies back to the atmosphere as CO2 by the process of respiration. In certain occasions, the dead plant and animals get converted into fossil fuel, which is available in future for combustion.

How are the law of independent assortment and the law of segregation different?

san4es73 [151]

Hi there!

The law of independent assortment says that the traits are randomly selected, there is no pattern to how they are sorted. The law of segregation says that the traits are divided between each gamete, using a pattern to sort them.

Hope this helps!! :)

Why does meiosis produce cells with half the chromosomes

Which of these is unique to flowering plants?

Aliun [14]

Answer:

Double fertilization. (Ans. 5)

Explanation:

Double fertilization is a complex fertilization process occurs only in flowering plants known as angiosperm. In this process two male gametes or sperm cells fertilization occurs, first one is fertilized with the egg and form the zygote and second one is fuses with the 2 polar nuclei which cause the formation of endosperm.

In double fertilization, after the process of fertilization, the tissue of ovary forming the fruit and fertilized ovule of an ovary forming the seed.

alex41 [277]

Answer:

Both C and E are reasonable answers.

Explanation:

Homeostasis describes the body's ability to maintain a stable equilibirum. In other words, if the body experiences a stress, it will generate a response that works to counteract that stress and restore itself to how it was prior to the stress.

A. This describes a cause and effect (BP down --> venous return down). It does not describe an active physiological response to counteract the BP drop such as an increase in heart rate. Not homeostasis.

B. Again, a cause and effect is described. Blood vessel walls becoming thinner is not a response to counteract increased BP. Not homeostasis.

C. Here a response to a stress is described. Men are drinking more water. The body responds by getting rid of that water, restoring the body to its former state. This describes homeostasis.

D. This sounds like homeostasis, but it's actually the opposite of what happens. Dilation of peripheral blood vessels is a way for the body to get rid of heat. This is the opposite of what you would want if the body got colder - it would make the stress worse, which is the opposite of homeostasis. In actuality the response to cold temperature is constriction of blood vessels to preserve heat.

E. This deescribes homeostasis. The stress is increased glucose. The body's response to manage it is to release insulin, which helps remove the glucose from circulation.
