A population of rabbits lives on one side of a wide river. Another population of rabbits lives on the opposite side of the river. They cannot cross the river. If speciation occurred as a result of the river, what kind of speciation was this? ___________
Answer:
Allopatric speciation
Explanation:
The kind of speciation that occurs when 2 populations of rabbits separated by water become different species is allopatric speciation.
Allopatric speciation occurs when two populations of the same organisms become physically separated and each population ends up developing unique characteristics that make them distinct species. This is as opposed to sympatric speciation in which a new species just spontaneously emerge from the existing population without any being separated from the population.
Other forms of speciations include parapatric speciation which occurs as a result of the spreading out of a population over a large geographical area and peripatric speciation which occurs as a result of the breaking off of a small group from a large group of organism.
In the illustration, the two populations of rabbits are separated physically by the river. Hence, the speciation that will occur if each population goes ahead to form a new species would be allopatric speciation.

Genetic testing could cause ecosystem damage by creating mutant mosquitos.
Answer:
i think it could reveal health risks
Explanation:
i hope that is correct!
Genetic testing results in some circumstances could be ambiguous or inconclusive. Detrimental effect on connections with family and friends. Thus, option C is correct.
What are negative impact of genetic testing in humans?The following are some drawbacks or hazards of genetic testing: Your stress and anxiety may increase throughout testing.
Results in some circumstances could be ambiguous or inconclusive. Detrimental effect on connections with family and friends.
Because the findings of genetic testing can expose information about family members besides the test subject, this causes conflict between families.
Another issue is the potential for genetic discrimination in insurance or the workplace.
Therefore, Genetic testing could cause discrimination by revealing health risks.

Explanation:
The mitochondria is known as the “powerhouse of the cell." Why?*
glucose is broken down into cellular energy (ATP).
lipids release energy as they form polypeptide bonds.
glucose is created through the process of photosynthesis.
proteins create energy as they are converted from sugars.
Answer:
The correct answer is - glucose is broken down into cellular energy (ATP).
Explanation:
Mitochondria is the double membrane cell organelle presents in all eukaryotic cells that produce the energy by the process of cellular respiration from the food to the cell to perform its day to day functions.
The cellular respiration is the process that involves the braking of the sugars into simple molecules and these catabolic reaction produce energy with CO2 and water as waste. The energy is stored in the form of ATP which is generated in the inner membrane of mitochondria. ATP is used by the cell to perform its function.
Thus, the prower house of the cell is mitochondria.
5.21 Unit Test: Water and Oceans - Part 1
What forms as a result of the wind's frictional force on water?
O deep sea currents that move in a path opposite to the wind currents
O surface currents that move in a path opposite to the wind currents
surface currents that move in a path similar to the wind currents
deep sea currents that move in a path similar to the wind current
Answer:
Surface currents that move in a path similar to the wind currents
Explanation:
One of the reasons of the movement of the surface of the oceans is the force of the blowing wind. When there is a movement of wind over the surface of the ocean, the surface friction is created. Because of this there is an energy transfer between the force of the wind and the surface of the ocean water. This results in the creation of roughness of the surface of the ocean. The more the surface area of the ocean, the more is the transfer of the energy.

The image shows a spruce tree, which is a gymnosperm.
Which characteristic can be used to classify the tree as a gymnosperm rather than "any other type of seed" plant?
naked seeds
green leaves
thick bark
tall height
Answer: Naked Seeds
Explanation:
Gymnosperm means 'naked seed' and these were the earliest trees to evolve. They do not produce flowers and have seeds which are directly exposed to the air for wind pollination. Pine cones are one example. For ease you might think of the gymnosperms as conifers, such as yew and Scots pine.
The exposed seeds characteristic can be used to classify the tree as a gymnosperm rather than "any other type of seed" plant.
What is gymnosperm?Gymnosperms are a small category of plants that don't blossom and produce "exposed seeds."
Unlike angiosperms, or flowering plants, whose seeds are enclosed by fully developed ovaries, or fruits, gymnosperms, or any vascular plant, reproduce by the use of an exposed seed, or ovule.
Many gymnosperms bear their seeds in cones, which are known as "exposed seeds" because they are not visible until they are fully developed.
This means that unlike in a fruit, where the seeds are formed inside the reproductive structure, they are produced on the surface of the reproductive structure.
Therefore, option A is correct.

i need help with this can someone help me?
Explanation:
Predation plays an important role in the overall health of an ecosystem since it regulates the population of preys as well as maintain the population of higher-level consumers. If predators were eliminated from an ecosystem, it would cause an increase of the population of preys and potentially decrease the population of other organisms on lower trophic levels. An example of such effect can be seen from the population of rabbits and plants supposing that foxes, eagles and snakes are eliminated from the ecosystem. The rabbit population will multiply, causing a decrease in the population of plants such as grass that rabbits feed on.

According to CDC, between 1998 and 2011, about 79% of the dairy-related illness outbreaks were caused by
cheese or raw milk (unpasteurized) products. 148 outbreaks and 2,384 illnesses were reported during that time.
284 required hospitalizations and 2 deaths were caused by cheese or raw milk products. Although these numbers
seem small, there are risks. At a federal level, although the FDA forbids the sale or distribution of raw
(unpasteurized) milk, 13 states allow the sale of raw milk in their retail stores, and another 17 states allow the
sale of raw milk on the actual farm that the milk was produced.
Explain the thinking that caused the FDA to forbid the sale and distribution of raw milk.
