The statement that is not true concerning the zebra mussel in the United States would be option "D" that it can be eliminated from a river with minimal effort.
What are the zebra mussels and why should we care about them?Zebra mussels are an invasive, fingernail-sized mollusc that is indigenous to freshwaters in Eurasia. Their name comes from the dark, zig-zagged stripes on each shell.
They probably arrive in the Great Lakes in the 1980s via ballast water that was discharged by huge ships from Europe. They have spread rapidly throughout the Great Lakes region and into the large rivers of the eastern Mississippi drainage. .
Thus, option "D" can be eliminated from a river with minimal effort.

In biology, a dichotomous key helps to identify and classify organisms based on similar features and structures
What is a dichotomous key?A dichotomous key is a tool used in biology to identify organisms based on similarities in their structure and function.
Organisms with similarities in their structure and function will be placed under the same category and any difference will be used to separate them.
For example in the dichotomous key for Shark, the features:
Fish with long tubelike body will identify sharksFish with body shape not tubelike will be used to separate fishes that are not shark.Therefore, a dichotomous key helps to classify organisms based on similar features and structures.

Daniel’s mother takes his baby sister Robin to the doctor for a regular check-up. The doctor tells her that the baby will start to get her first vaccinations on the next visit. His baby sister is a formula-fed baby. Why will the vaccinations provide immune protection for Robin?
Vaccines will provide immune protection for Robin because immunization is one of the main ways to prevent disease. Through it, the body is protected from viruses and bacteria that seriously affect the human being, which can lead to death.
Why vaccinate?After application of doses, the vaccine interacts directly with the patient's immune system, thus producing a response similar to that generated by natural infection. However, it does not cause illness or risk the life of the immunized patient due to possible complications of a naturally caused disease.
With this information, we can conclude that vaccines will provide immune protection for Robin because immunization is one of the main ways to prevent the disease. Through it, the body is protected from viruses and bacteria that seriously affect the human being, and can lead to death.

describe the goals of maximum sustainable yield management, ecosystem based management, and adaptive management. list a drawback of each
In this question we will describe the management goals of maximum sustainable yield, ecosystem-based management and adaptive management.
What is a sustainable management plan?A sustainable management plan aims to maximize forest production and minimize damage to the remnant responsible for the productive, structural, functional and genetic support of the exploited forest.
What is ecosystem-based adaptation?Ecosystem-based adaptation protects vulnerable communities from extreme weather while providing a variety of crucial benefits for human well-being, such as clean water and food.
What is Adaptive Management?Adaptive Management is a management approach developed to provide organizational systems with a greater degree of adaptability, seeking to provide means to increase the speed of response to environmental pressures and improve the quality of this response.
With this information, we can conclude that the disadvantages of these methods are that they will bring harm to the affected ecosystem.

Why is it important to have species specific sperm egg binding.
Answer:
to restrict the gene pool to individuals
of the same apecies.
Explanation:
abstract. species-specific adhesion of sperm to the egg during sea urchin fertilization involves the interaction of the sperm adhesive protein, bindin, and a xomplemetary receptor on the egg surface, and serves to restrict the same gene pool to individuals of the same species.The inner planets are Mercury, Venus, Earth, and Mars. These four planets are small and solid and have few or no moons. All but Mercury have an atmosphere large enough to create weather.
The outer planets are Jupiter, Saturn, Uranus, and Neptune and are all gas giants. These large planets are composed of gasses such as hydrogen and helium and ices. They have many moons--Jupiter has sixty-six!

In guinea pigs, the allele for black fur (B) is dominant over the allele for white fur (b). A black male guinea pig is mated to a white female guinea pig. The offspring were 7 black and 6 white guinea pigs. What are the genotypes of the parents?
Answer:
Male: Bb
Female: bb
Explanation:
1. I made punnet squares to test each genotype pairs:
BB (black male) x bb (white female)
Bb (black male) x bb (white female)
** B is dominant over b so if Bb, black will be expressed
3. I calculated the percentage of each phenotype to see if it matched the the number of white and black guinea pigs produced. I found that Bb x bb had 50% chance for white guinea pigs and 50% chance for black guinea pigs, which is about the same in the scenario above (7 black, 6 white).
4. I infered that the male black guinea pig's genotype is Bb and the female white guinea pig's genotype is bb.
In a diploid cell with the genotype RrYyPp , how many different haploid cell genotypes could be created if all three genes show independent assortment
A total of 8 different haploid cell genotypes will be formed if all the three genes show independent assortment.
Independent assortment
The genes of RrYyPp assorting independently means they are not linked in any way.
During meiosis, the genes separate to produce haploid gametes as follows:
RYP
RYp

What kind of relationship does mistletoe
have with the oak tree? Explain your answer.
Answer:
Parasitic symbiosis is when one organism exploits the other. For example, the mistletoe that grows on oak trees at the Table Rocks is a parasite; it sinks its roots into the oak and steals water and nutrients. The oak suffers from the association; a heavy mistletoe infestation can even kill the tree.
