Nonnative species can cause serious problems with marine ecosystem biodiversity. The graph shows a summary of the different methods by which invasive species reach new locations based on United States Geological Survey data as of 2016. Based on this information, what recommendation could be made to reduce introductions?
A- Methods should be put in place to reduce the ability of species from escaping from captivity and establishing themselves in new locations.
B- People should take extra care when setting up a home fish tank to be certain that all organisms in it will be properly maintained so that the animals remain healthy and diseases are not spread.
C- Science should more closely study the genetics of the different organisms used to prevent mixing of DNA.
D- Ships should install some form of cleansing mechanisms before releasing their ballast water during transport and should be checked for unintended cargo.
Answer: D
Explanation: 20% of invasive species are introduced by Shipping so checking the ballast tanks in cargo ships would help the most I think
To reduce introductions of Non-native species, ships should install some form of cleansing mechanisms before releasing their ballast water during transport and also check for unintended cargo.
What are non-native species?Non-native species are also called invasive species. They are called so as they are foreign or not indigenous to a particular ecosystem and have been introduced to the said ecosystem by some unnatural methods.
These species show a high capacity for adaptation to their new environment. They quickly multiply and reproduce and therefore increase in population.
This sudden and unnatural increase in their population soon after they are introduced to a new environment will greatly affect the ecosystem of the new environment. The new species will compete with the native organisms of that environment for resources. This may cause the native flora or fauna to become endangered or even extinct.
The accidental introduction of invasive species happens quite often and causes a lot of problems. In a marine ecosystem, it happens a lot due to the ships that travel through a variety of marine regions.
So, ships should install some form of cleansing mechanisms before releasing their ballast water during transport and should be checked for unintended cargo.
Therefore, the correct option is D.

What acts as the final destination for chromosomes during mitosis?
Answer:
Telophase
Explanation:
if you're asking what the final stage of mitosis is called
Answer:
Telophase
Telophase is the fifth and final phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. Telophase begins once the replicated, paired chromosomes have been separated and pulled to opposite sides, or poles, of the cell.

A genetic experiment with peas resulted in one sample of offspring that consisted of green peas and yellow peas.444167a. Construct a %confidence interval to estimate of the percentage of yellow peas.90b. It was expected that 25% of the offspring peas would be yellow. Given that the percentage of offspring yellow peas isnot 25%, do the results contradict expectations
Answer: a.) 0.2438 < p < 0.3028
b.) No
Explanation: Confidence Interval to estimate the percentage of yellow peas is calculated following these steps:
1) Total of the offspring in one sample:
n = 444 + 167
n = 611
2) Proportion of yellow peas, which is the number of yellow peas observed divided by the total of offspring:
p = [tex]\frac{167}{611}[/tex] = 0.2733
3) For a 90% confidence interval:
α = 1 - 0.90
[tex]z_{\alpha/2}=z_{0.05}[/tex]
Checking z-table, z-score will be: z = 1.645.
4) Calculate margin of error:
[tex]E=z.\sqrt{\frac{p(1-p)}{n} }[/tex]
[tex]E=1.645.\sqrt{\frac{0.27(1-0.27)}{611} }[/tex]
E = 0.0295
5) Confidence interval has boundaries:
p - E = 0.2733 - 0.0295 = 0.2438
p + E = 0.2733 + 0.0295 = 0.3028
Then, we are 90% confident that the percentage of yellow peas is between 24.38% and 30.28%.
b.) Since 25% is in the confidence interval, and we are 90% sure the true percentage of yellow peas are inside the interval, the result does not contradict the expectations.

1. Identify one population of organisms shown in the food web, other than rabbits or mice, that would likely be affected by the introduction of snowy owls AND explain why their population would be affected.
2. State which level, a, B, or C, contains the least total available energy. Support your answer.
Answer:
The population if snakes will decline because there will be competition between snakes and snow owls. The snow owls will eat the mice, but if there's only a small population of mice. Only a few snakes will eat, other snakes will die of starvation. There will be competition between snow owls, hawks and mountain lions, but they have other sources of food, unlike snakes.
Level C contains the least amount of energy. This is because each level gets less and less energy per meal, beacuse energy is released by each organism.

C. All animals in the rain forest have the same adaptations.
D. Animals in the rain forest all need the same amount of sunlight.
i think answer is D animal in the rain forest
All animals in the rainforest have the same adaptations. Therefore, option C is correct.
What is adaptation?A physical or behavioral characteristic of an animal that enhances its ability to survive in its environment is known as an adaptation.
To put it another way, an adaptation is something a person does or has on them that makes it easier for them to locate food, water, mates, and shelter. The structural adaptations made by some plants to survive in hot, dry deserts are one illustration of this.
Animals can defend themselves against predators and extreme weather by adapting. Numerous birds may conceal themselves under long grass, while weeds, insects, and other creatures can alter their colour to blend in. Predators find it challenging to locate them in search of food as a result. Hence, option C is correct.

Malaria, a type of parasite, infects 500 million people each year by infecting the red blood cells of its host. The virus, HIV, that causes AIDS, reports 50,000 newly infected persons. Which statement best differentiates the pathogens, parasites and viruses?
options: Although both rely on other living organisms to survive, viruses are usually beneficial.
Although both rely on other living organisms to survive, parasites feed on the host organism.
Although both are living organisms, viruses break down dead plants and animals that other organisms use.
Although both are living organisms, parasites depend on the cells of living things to reproduce.
Answer:
The second statement clearly differentiates the pathogens best. Parasites feed on living host while viruses depend on the cells of other organisms to survive and reproduce as they cannot function outside a living host.
Although both rely on other living organisms to survive, parasites feed on the host organism. The correct option is B.
What are parasites?A parasite is an organism that lives on or in the host and obtains its food from or at the expense of the host.
Protozoa, helminths, and ectoparasites are the three main types of parasites that can cause disease in humans.
They frequently go unnoticed because they have few symptoms. However, these infections frequently result in serious illnesses such as seizures, blindness, heart failure, and even death.
A parasitic relationship takes place when one lifeform, the parasite, feeds on another organism, the host, causing harm and possibly death.
The parasite lives on or in the host's body. Tapeworms, fleas, as well as barnacles are examples of parasites.
Thus, the correct option is B.

AZT is a drug that is commonly used to fight HIV infection. The active component of AZT is a nitrogenous base that mimics thymine. Normal nucleotides CANNOT covalently bond to the thymine mimic. HIV's reverse transcriptase enzyme will use the thymine mimic instead of using thymine, whereas our DNA polymerase will not make this mistake. What is the most likely explanation for how AZT prevents HIV replication
AZT works by selectively inhibiting HIV's reverse transcriptase, the enzyme that the virus uses to make a DNA copy of its RNA. Reverse transcription is necessary for production of HIV's double-stranded DNA, which would be subsequently integrated into the genetic material of the infected cell to produce its proteins. All reverse transcriptase inhibitors are analogues of the naturally occurring deoxynucleotides needed to synthesize the viral DNA and they compete with the natural deoxynucleotides for incorporation into the growing viral DNA chain.

The best way to practice sustainable use of rangelands is to
Answer: 1. Rotating the rangelands that are being used.
2. Reducing overgrazing of rangelands.
Explanation:
Rangelands are the sites which are occupied and dominated by vegetation cover mostly the shrubs and herbs. It can be occupied by grasses. Overgrazing by the cattle cause a huge damage to the field of rangeland so it can cause soil erosion and can convert the rangeland on barren land. The regrowth rate is slower than that of the consumption rate of the cattle. So, reduction in overgrazing is advisable to maintain the sustainability of the land. Rotation of the rangelands being used if the cattle are taken to the different grassland for grazing on alternate days then the rangelands can be maintained sustainably.
