Lions live in the south Sahara Desert in breeding groups called prides. Females tend to stay in their pride, but males may leave to join another pride. Which mechanism does this describe?
The correct answer to this open question is the following.
Although there are no options attached we can say the following.
This mechanism describes the necessity of males to lead and form their own pride to show their dominance and power. That is why young lions leave and wander, and when they are ready, they fight for their right to lead their own pride.
So yes, Females tend to stay in their pride, but males may leave to join another pride. And that is the male instinct for lions in the wildlife.
On the other hand, males tend to stay in the same pride, taking care of their cubs, raising them, and hunting. That is what they do best, hunt animals to feed the pride and the cubs.
Cytosine makes up 30% of the nucleotides in a sample of DNA from an organism. What percent of the nucleotides in this sample will be adenine?
Answer:
20%
Explanation:
The four different bases pair together in a way known as complementary pairing. Adenine always pairs with thymine, and cytosine always pairs with guanine.
if adenine makes
The guanine percent is 30. This is because the other 30% of the 60% is cytosine. Getting back to adenine, it always partners up with thymine as i mentioned before, So it would be 20% thymine and 20% adenine, add those portions to the 60% of the other two, mentioned above and you have 100%.

2. What is life processes
3.Formula of photosynthesis
Answer:
Explanation:
what is #2 asking?
1.) respiration is the action of breathing. It produces energy, we take in oxygen as we inhale and when we exhale we release carbon dioxide.
2.) to reproduce and survive?
3.) carbon dioxide + water⇒ sugars + oxygen
CO2 + H2O energy/sunlight ⇒C6H12O6+ O2
Answer:
1 respiration is the inhaling of oxygen and exhaling of carbon dioxide
2life process is the activities of living organisms such as respiration, reproduction,digestion and circulation
3photosynthesis----carbon dioxide + water + chlorophyll + oxygen

Describe how protists are helpful and harmful to humans and other organisms. (1 paragraph)
Describe how fungi are helpful and harmful to humans and other organisms. (1 paragraph)
PLEASE HELP!!!!!
Answer:
Plant-like protists produce almost one-half of the oxygen on the planet through photosynthesis. Other protists decompose and recycle nutrients that humans need to live. For example, medicines made from protists are used in treatment of high blood pressure, digestion problems, ulcers, and arthritis. Fungi are very important ecologically, because they are one of the most important decomposers in most ecosystems. They help to break down plant fibers such as dead leaves and wood and allow the nutrients to be released into the soil. Fungi are useful to humans because they have economic value.
Explanation:
Why do very few plants live in streams?
Answer: Very few plants Survive in deep water because concentration of oxygen is less therefore very few plants develop the ability to catch oxygen from water
Explanation:
Efforts to reduce pollution began occurring later in the century. If pollution near factories was reduced, what would happen to the color of the moths? Explain your answer.This would happen because
Answer:
moths would begin becoming lighter as the pollution is reduced
Explanation:
The color of the moths would begin becoming lighter as the pollution is reduced. This is because during the time of high amounts of pollution industrial melanism takes place and the moth's pigmentation becomes a darker tone. This is so that the moths are able to blend in better with its surroundings and survive. Pollution causes sulphur dioxide gas and dark soot deposits which have a greyish dark tone, thats why moths pigmentation turns darker. With pollution reduced moths need a lighter colored pigment to blend into lighter colored objects such as trees and leaves.
The color of the Moths will become lighter as a result of this due to the effect
pollution has on its color.
Industries and factories make use of fuel and when it is burned in generating
sets and other equipment it produces the compound known as Nitrogen
oxide.
The Nitrogen oxide has a brownish color which goes into the atmosphere
where the moths fly in thereby contact with the gas darkens the color to
shades of brown. A reduction in the discharge of the gas will lead to it
becoming lighter.

If someone has a heavy weight on his or her chest, explain why after a short time it becomes difficult to breathe, even though the person’s mouth and nose are not affected
Answer:
When you breathe, air flows from your nose or mouth to your lungs, the lungs expand to allow the air in, and then they contract to remove the air from your body, then you exhale that air.
Then you can see that in the breathing process, your lungs need to expand. If you have a heavy weight on your chest, then the amount that your lungs can expand is really small, then the amount of air that they can have is smaller than normal. This is why is harder to breathe when you have a heavy weight on your chest.

Explanation:
AB blood type in humans as well as, red and white striped flowers are examples of this type of inheritance pattern.
Answer:
The inheritance pattern is CODOMINANCE
Explanation:
Codominance is a type of non-mendelian inheritance i.e. does not follow Mendel's principles of inheritance, in which two alleles of a gene are both dominant, hence, they are both simultaneously expressed in that gene.
Examples or cases of codominance are the AB blood type in humans where alleles A and B are both expressed in the gene. Also, red and white striped flowers in certain plants is an example of codominance as red and white alleles are both expressed.

During Earth's early history, microbial life on land contributed to the formation of soil. Soil formation, in turn, led to the evolution of land plants. Which term describes this chain of events?
Answer:
The correct answer is - nitrogen fixation.
Explanation:
In soil formation microbes play an important role as they help in providing important compounds such as nitrogen by the process of nitrogen fixation that is used by the plants.
Nitrogen-fixing organisms mostly bacteria are free-living but some live in a symbiotic relationship with plants such as Azobacter or with other organisms such as Rhizobium.
