Genetic variation results in different forms, or alleles?, of genes. For example, if we look at eye colour, people with blue eyes have one allele of the gene for eye colour, whereas people with brown eyes will have a different allele of the gene

How might adding trees, other plants, and phytoplankton to the biosphere impact global climate change?
astraxan [27]

Answer:

B) The biosphere will absorb carbon dioxide, and the temperature of the atmosphere may decrease or the warming of the atmosphere will slow.

Explanation:

The Climate is constantly influenced by changes caused by the increase in global temperature called Global Warming. Global warming is caused by the emission of green house gases which includes carbondioxide (CO2). Hence, one way to prevent the climate from further deterioration is to find a way of removing gases like CO2 from the atmosphere.

Plants like trees and phytoplanktons like algae are photosynthetic organisms. This means they have the ability to perform the process of photosynthesis, which is the usage of light energy from sun to synthesize food in form of organic molecules (glucose) from an inorganic source. The inorganic source is Carbondioxide (CO2). Plants take in CO2 via the stomata on their leaves. Carbondioxide is a vital raw material for photosynthesis, hence, the photosynthetic process helps remove Carbondioxide from the atmosphere.

If trees, other plants, and phytoplankton are added to the biosphere, they will perform photosynthesis and absorb a good amount of Carbondioxide (CO2), which contributes to global warming, from the atmosphere. Hence, the temperature or warming of the atmosphere caused by global warming will decrease.

I have a very important question today. NEED ANSWERS QUICK... FAMILY MEMBER NEEDS THIS ANSWER.
iris [78.8K]

Answer:

A very small number of bone cancers (especially osteosarcomas) appear to be hereditary and are caused by defects (mutations) in certain genes. Retinoblastoma is a rare eye cancer in children that can be hereditary. The inherited form of retinoblastoma is caused by a mutation (abnormal copy) of the RB1 gene. Those with this mutation also have an increased risk of developing bone or soft tissue sarcomas. Also, if radiation therapy is used to treat the retinoblastoma, the risk of osteosarcoma in the bones around the eye is even higher. Finally, there are families with several members who have developed osteosarcoma without inherited changes in any of the known genes. The gene defects that may cause cancers in these families haven’t been discovered yet.

They will most likely survive becuase stage one of bone cancer is the most treatable stage.

Digestion of food occurs in the small intestine. No further digestion takes place when food passes from the small intestine to t
Aliun [14]

Here is your answer:


This statement is "false" or the second option. Digestion takes places as soon as you put food in your mouth. That's because your saliva has chemicals that starts to break down the food as soon as you put it in your mouth. Then it goes down through your esophagus then through your stomach going through the primary intestines but when it gets to the small intestine that's when it sucks all the nutrient's out of the food that would give the body energy and gets rid of the food that won't.


Hope this helps!

What is the indication for the use of magnesium in cardiac arrest?
a_sh-v [17]

If there is suspected hypomagnesemia present that’s the time that you can use the magnesium. This is for use in cardiac arrest.  This kind of drug is life threatening ventricular arrhythmias due to digitalis toxicity. There is insufficient evidence to recommend for or against the routine administration of magnesium during cardiac arrest. Magnesium is for the treatment of documented hypomagnesemia or for torsade de pointes.
