What role does cellular respiration play in the carbon cycle?

2 answers:

7 0

During cellular respiration, carbon dioxide is released to the atmosphere during the formation of acetyl coenzyme A. This step involves the oxidative decarboxylation of pyruvic acid, the result of which is carbon dioxide. This carbon dioxide is uptaken by plants and used in the process of photosynthesis to produce glucose.

Which statement summarizes the law of independent assortmnt?

Sedbober [7]

The Principle of Independent Assortment describes how different genes independently separate from one another when reproductive cells develop. Independent assortment of genes and their corresponding traits was first observed by Gregor Mendel in 1865 during his studies of genetics in pea plants.

1.Write the part of the brain that preforms each of the functions shown below.

Damm [24]

The parts of the brain of a living organism which perform each of the functions are listed as follows:

Hypothalamus: it regulates sleep.

Optic nerve: it connects brain and eyes.

Cerebellum: it controls balance.

The frontal lobe: it controls thinking.

The brain stem: it controls breathing and heart rate.

The nucleus accumbens: it is the pleasure center.

<h3>What is a brain?</h3>

A brain can be defined as an organ of soft-nerve tissue that is found within the skull of vertebrates, and it's mainly responsible for the coordination of nervous activities, sensation and intellect in living organisms.

Based on scientific records and information, the two (2) sides of the brain (symmetrical left and right hemispheres) are able to communicate through the corpus callosum.

In conclusion, we can infer and logically deduce that the parts of the brain of a living organism which perform each of the functions are listed as follows:

Hypothalamus: it regulates sleep.

Optic nerve: it connects brain and eyes.

Cerebellum: it controls balance.

The frontal lobe: it controls thinking.

The brain stem: it controls breathing and heart rate.

The nucleus accumbens: it is the pleasure center.

An experiment was performed to study the progress of cells through the mitotic cell cycle. The compounds listed below were used

Hatshy [7]

<h2>Mitotic Cell Cycle</h2>

Explanation:

a. Cytochalasin: an inhibitor of actin microfilament

Cytokinesis is the process by which cytoplasm is divided into two cells hence generation of two daughter cells
In animal cells the division of cytoplasm starts with the assembly of contractile ring
Contractile band consists of actin and myosin and catalyze cleavage furrow formation
Cytochalasin is a drug that blocks the polymerization of actin filament
When cytochalasin is added dividing cell fails to undergo in cytokinesis due to defective assembly of contractile band

b. Colchicine: an inhibitor of microtubule formation

Colchicine tightly binds with free tubulin dimer and prevents its polymerization
In this case mitotic spindle apparatus do not assemble and cells unable to do partitioning of chromosomes into two groups
Thus cell division is arrested

c. Aphidicolin: an inhibitor of DNA Polymerase activity

Aphidicolin is used to induce cell cycle arrest via specific inhibition of DNA Polymerase α
It blocks the cell cycle at early synthesis(S) phase

d. Emetine: an inhibitor of ribosome activity

It blocks the protein synthesis in eukaryotic cells by binding to small subunit(40 S) of ribosomes
It interferes with the synthesis and activities of DNA and RNA

If there was a fungicide that killed all fungi, make a prediction on how it would affect the economy and eventually is humans

Lady bird [3.3K]

Hello!

Fungi are natural decomposers in ecosystems. They break down waste and dead organisms, and return the nutrients back into the ecosystem so more plants can receive nutrients, animals can eat those plants, and so on and so forth.

If all the fungi died out, things that decompose it will remain, and the nutrients will not return to the ecosystem. This will cause the plants to receive less nutrients, along with the animals, and as the cycle continues plants will not have enough nutrients to become a sustainable food source. If this happened, the herbivores would not have food and die out. The creatures that eat the herbivores would not have their food either. Eventually us humans will not have good food sources due to lack of nutrients.

In terms of the economy, many animals are sold in the stock market or sent to stores for humans to buy. If there was a large decrease in cattle, for example, the cattle stock would disappear and all the shares in that stock would be lost. This would make a lot of problems, and as the stock market is very complicated and large scale it would be an absolute disaster if an entire stock disappeared. It also wouldn't be JUST cattle. Wheat, corn, and crop stocks would be lost too. Other animal or livestock stocks would be lost as well. This could eventually cause the stock market to crash in a way, which would lead to the Great Depression. Just because of fungicide.

It's not like you would put down some fungicide and the stock market would crash a month later. It would be a very slow and gradual thing, which is good so we can keep things like that from happening right now!

Hope this helped!
