Answer:
why is it important
Healthy marine ecosystems are important for society since they provide services including food security, feed for livestock , raw materials for medicines, building materials from coral rock and sand, and natural defenses against hazards such as coastal erosion and inundation.
How does it effect humans:
Recreation, tourism and water transport are familiar services provided by many marine ecosystems. Some unique estuarine, coastal, and marine habitats are also important stores of genetic material and have educational and scientific research value as well.

Losing 100 orangutans a week is an astonishing number. Within your lifetime they could become extinct in the wild because of human impact. We use palm sugar in many products consumed and other things. Do you feel that it could be said we have a parasitic relationship with orangutans? Defend your answer.
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.

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.
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.

Why are there more mutations in RNA
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.
The different functions of the skeletal system include all of the following EXCEPT: *
a) Forms blood cells
b) Protects internal organs
c) Stores hormones
d) Assists movement
Which type(s) of muscle can contract without stimulation from the nervous system? *
a) skeletal only
b) skeletal and smooth
c) smooth and cardiac
d) cardiac only
Which of the following are events following fertilization? (Check all that apply. There may be more than one answer). *
a) Embryo develops into the fetus
b) Zygote cell rapidly divides
c) Embryo embeds into uterine wall
d) Zygote travels down the fallopian tube toward the uterus
Storing hormones, smooth and cardiac muscles are the correct answers.
Storing hormones is not function of skeleton system. Skeleton system protects internal organs such as heart, kidney and lungs etc. It is also responsible for the movement of the muscles as well as produces blood cells because of the presence of bone marrow.
Smooth and cardiac muscles can contract without nervous system stimulation because they are involuntary Muscle which is beyond the control of the nervous system so we can conclude that storing hormones, smooth and cardiac muscles are the correct answers.

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.
Answer:
The exposed dirt makes it easy for seeds to drop into the area and they are able to grow because they have room, sunlight, and water. As time passes, they will go through the cycle that dandelions go through and it will repeat itself each summer
