if the orangutans eat the fruits, basically their place of residence is their only means of obtaining and if the human continues to cut down trees and destroy forests, the fruits will be lost and the monkeys will starve and thus could become extinct.

Infrastructure Expansion.
Overpopulation.
2.Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play.
For example, A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms
3. In the rainforest, most of the carbon and essential nutrients are locked up in living vegetation, dead wood, and decaying leaves. As organic material decays, it is recycled so quickly that few nutrients ever reach the soil, leaving it nearly sterile.
4. The surplus carbon is stored in the plant, helping it to grow. When trees are cut down and burned or allowed to rot, their stored carbon is released into the air as carbon dioxide. And this is how deforestation and forest degradation contribute to global warming.
5. Restore damaged ecosystems by planting trees on land where forests have been cut down. Encourage people to live in a way that doesn't hurt the environment. Establish parks to protect rainforests and wildlife. Support companies that operate in ways that minimize damage to the environment.

Explanation:
In snapdragons, flower color is determined by a gene with two alleles. Red flower color (R) shows incomplete dominance over the gene for white flower color (R'). A scientist is observing the genes and genotype of a snapdragon population. Which observation provides evidence that the population is evolving?
A) The alleles R and R' have unequal frequency in the population.
B) The population is decreasing, and the allele frequencies remain the same.
C) The allele R' is becoming more common in the population.
D) The population is increasing, and the allele frequencies remain the same.
Answers
Answer:
C) The allele R' is becoming more common in the population.
The observation from this experiment provides the evidence that the population is evolving and the allele R' is becoming more common in the population. Thus, the correct option is C.
What is Incomplete dominance?Incomplete dominance is the form of gene interaction which results from a cross in which each of the parental contribution is genetically unique and the allele gives rise to progeny whose phenotype is intermediate of the two parental genotypes and phenotypes. Incomplete dominance is also referred to as semi-dominance or partial dominance. It is an exception of the Mendel's law of dominance.
From the observation made in the experiment, it can be said that the allele R' which is responsible for white colored flowers in the plant are becoming more common in the population.
Therefore, the correct option is C.

I need help with the diagram
Answers
Explanation:
Answer:
Explanation: Animal cells are eukaryotic cells or cells with a membrane-bound nucleus. Unlike prokaryotic cells, DNA in animal cells is housed within the nucleus. In addition to having a nucleus, animal cells also contain other membrane-bound organelles, or tiny cellular structures, that carry out specific functions necessary for normal cellular operation. Organelles have a wide range of responsibilities that include everything from producing hormones and enzymes to providing energy for animal cells.
The answer
Key Takeaways
Animal cells are eukaryotic cells that have both a membrane-bound nucleus and other membrane-bound organelles. These organelles carry out specific functions that are needed for the normal functioning of the cell.
Plant and animal cells are similar in that they are both eukaryotic and have similar types of organelles. Plant cells tend to have more uniform sizes than animal cells.
Cell structure and organelle examples include: centrioles, the Golgi complex, microtubules, nucleopores, peroxisomes, and ribosomes.
Animals typically contain trillions of cells. Humans, for example, also have hundreds of different cell types. The shape, size and structure of cells go along with their specific function.

Why are there more mutations in RNA
Answers
Answer:
There are more mutations in them because in viruses they allow them to evolve to survive drugs and evolve more rapidly.
Explanation:
Answer:
Average mutation rates in RNA viruses are estimated to be about 100 times higher than those in DNA viruses for a couple of reasons.
Replication errors
The enzymes that occur in RNA viruses and participate in copying viral genomes is a key reason for this difference. These enzymes lack the built-in capabilities to recognize DNA damage that enzymes in most organisms have.
Retroviruses take their RNA-based genome, use it to make DNA within a host cell and use the new DNA to replicate more viral RNA. This process is error-prone and results in an unusually high mutation rate. HIV, for example, has a mutation rate of 3.4 x 10^-5 errors per base pair each time its genome goes through this process. Retroviruses have higher mutation rates than most other viruses, including other RNA viruses.
Another interesting difference between RNA and DNA mutations involves the bases thymine, cytosine and uracil, typically represented as T, C and U in the DNA code. DNA uses thymine, while RNA uses uracil instead. Cytosine can sometimes spontaneously change to uracil by deamination. In DNA, this error will be detected because DNA doesn't ordinarily contain uracil; the cell has enzymes that can recognize and fix the substitution. In RNA, however, this kind of error cannot be detected because RNA ordinarily contains both cytosine and uracil bases. So, some mutations are less likely to be recognized and repaired in RNA viruses, and the mutation rate increases.

write a paragraph to show your knowledge about diabetes that include the following terms:
Glucose, Glucagon, Pancreas, Negative Feedback, Homeostasis, and Liver
Answers
Answer:
Glucose is a simple sugar molecule that helps play a role in high/low blood sugar levels. If your blood level is too low Glucagon is released to increase your blood sugar and if it’s too high Insulin is secreted to lower blood sugar; both Insulin and Glucagon are hormones.This being said these two hormones are secreted by the pancreas. Both of these two hormones are examples of negative feedback leading to a stability In homeostasis. It is regulated by the liver, however if homeostasis is disrupted the body will stop functioning properly leaving no insulin to be produced. Therefore the end result is Diabetes

layers that are billions of years old.
0 Fossils of species that no longer exist but are ancestors of
current species have been found in rock layers.
Answers
Fossils of species that no longer exist but are ancestors of current species have been found in rock layers. Thus, the correct option is D.
What are Fossil fuels?A fossil fuel is a hydrocarbon-containing material which is formed naturally in the Earth's crust from the remains of dead organisms such as plants and animals which are extracted and burned as a fuel. The main fossil fuels which are present in the earth's crust include coal, oil, and natural gas.
The evolution of species is easily confirmed by the presence of fossils of the most diverse species of the living beings in the world. This is because, fossils are the records of species which do not currently exist, however there are existed millions of years ago and are similar to the current species, being their ancestors.
Therefore, the correct option is D.

Sod or turf is grass with the top layer of soil held together by the grass roots. A sod farmer cuts strips of turf and rolls them up for delivery. The fresh sod is used in sports stadiums, golf courses, and lawns.
Back where the turf was removed is an empty expanse of bare dirt. Within a day, seeds from dandelions are dropped by the wind. There is plenty of sunlight and space for the new seeds. No other plants are around to compete. The new plants grow quickly in their habitat and produce many seeds.
Describe how natural selection affects the dandelions just after they arrive and as time passes.
