Two insect groups vary genetically by two genes. When put together, they were able to reproduce and produce offspring that could also breed. Which best describes this insect population?
The insects experienced geographic isolation.
The insects experienced reproductive isolation.
The insects are different species.
The insects are the same species.
Answer:
The insects are the same species.
Explanation:
The insects are the same species because they interbreed with each other successfully. If the organisms belongs to the same species, they have the ability to interbreed with each other and produce fertile offspring while on the other hand, different species can't interbreed with one another. These two organisms have some genetic variations among each other due to environmental factors that leads to the differences between these two organisms.
The insects are the same species because they were able to reproduce and produce offspring that could also breed.
What are species?Species are a group of related organisms which are able to interbreed and produce reproductively viable offspring.
The species level of taxonomy is the closest relationship and has the fewest number of organisms.
Since, the two insect groups were able to reproduce and produce offspring that could also breed, they are of the same species.

When pure black hamsters were mated with pure white hamsters, all of the offspring were black. The trait for whiteness would best be described as?
Answer:
Recessive
Explanation:
All of the offsrping were black so that means black was the dominant gene and white was the recessive
At the time when the pure black hamsters were mated so here, the whiteness trait should be called the recessive.
What is recessive?It refers to the allele type that should not be manifested in an individual till both individual copies of the gene should include the particular genotype.
And, all the offspring should be considered as black so here black treated as the dominant gene and white should be considered as the recessive
Hence, the whiteness trait should be called recessive.

Can someone name and explain each lymph organ?
Answer:
The lymphatic system consists of all lymphatic vessels and lymphoid organs. For example, the lymph nodes, spleen, thymus as well as the lymphatic tissue found in the small intestine (Peyer’s patches) and throat (adenoid tonsils, palatine and tubal tonsils), to name a few, all represent lymphatic organs.Hence, rather than representing a single organ, the lymphatic system comprises a circulatory network of vessels and lymphoid tissue and cells in every part of the body. It works together closely with the blood-producing (haematopoietic) system in the bone marrow, thereby playing a vital role in immune responses to protect the body from various pathogens. Also, the lymphatic vessel network helps transporting nutrients and waste products in the body.

Each planet spins on an epicycle.
The Sun is at the center.
The Earth was at a point slightly offset from the center.
The stars are attached to the outermost sphere.
Earth is at the center.
Each planet is attached to a crystalline sphere.
Answer:
The Earth is at the center
Explanation:
Aristotle was the first to believe the earth was round but he still thought everything revolved around the earth.
Aristotle's geocentric model of the solar system was based on the belief that the planet moves around the earth at the same speed.
One peculiar thing about this model was that the earth was said to be at the centre, which is why it is described as the geocentric model.

explain how the adaptation to reproduce quickly is beneficial in bacteria's ability to
develop resistance to antibiotics
Answer:
Antibiotics save lives but any time antibiotics are used, they can cause side effects and lead to antibiotic resistance.
Since the 1940s, antibiotics have greatly reduced illness and death from infectious diseases. However, as we use the drugs, germs develop defense strategies against them. This makes the drugs less effective.

2. Why is it possible for different species of penguins to live in different climates?
3.What are some environment factors and their impact?
4.What is the carrying capacity of an ecosystem?
5.What kind of factors do you think can change a carrying capacity?
6. Compare artificial selection to natural selection?
7. How do environment factors and genetic factors affect natural selection?
Adaptation is the evolutionary process whereby an organism becomes better able to live in its habitat or habitats. 2. Adaptedness is the state of being adapted: the degree to which an organism is able to live and reproduce in a given set of habitats.
On the western peninsula, the changing climate means different weather is turning sheets of snow and ice into a land of rain and mud. Older penguins are equipped with waterproof layers of feathers allowing them to move swiftly in the water, and also allowing them to stay warm on land.

Carrying capacity can be defined as a species' average population size in a particular habitat. The species population size is limited by environmental factors like adequate food, shelter, water, and mates. If these needs are not met, the population will decrease until the resource rebounds.
6.Natural selection and selective breeding can both cause changes in animals and plants. The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene. For this reason selective breeding is sometimes called artificial selection.
The population of white pines on his land in 2015 was 40. After last weekend the population is 155. Find the growth rate.
Answer:
287.5%
Explanation:
Initial = 40
Recent = 155
Growth rate = ( recent - initial )÷ initial ×100/1
=( 155-40/40) × 100/1
= 115/40×100/1
= 2.875×100/1
= 287.5%
The rate of growth is 287.5%
WILL GIVE BRAINLIST!!!!! what are 3 ways that animals and plants can erode rocks in different locations?
Answer:
Hope this Helped :)
Explanation:
1.Biological weathering-Plants and animals release acid forming chemicals that cause weathering and also contribute to the breaking down of rocks and landforms.
2.Plants change Earth’s surface through weathering and erosion.They take minerals from the rock. This is a type of weathering, and it weakens the rock. Eventually the surface of the rock starts to break down and become soil.
3.As larger plants like trees start to grow in a rocky area, their roots
grow into the small cracks in the rock. Slowly, as the tree grows, its roots break the rock apart. This forms more soil and makes it easier for other plants to grow there as well.
4.When too many animals live in one place, they tend to eat and trample all the plants. Without the plants to protect the soil, it is more likely to be eroded by wind and water.

What would happen to a deep sea fish brought rapidly to the surface? Explain your answer in light of the fact that gas pressure in the swim bladders of some deep sea fishes increase up to about 300 atmospheres. Also define an atmosphere as it relates to the oceans.
Answer:
Its gas-filled swim bladder explode.
Explanation:
The gas-filled swim bladder of deep sea fish is explodes when brought to the surface too rapidly because in the deep sea there is high pressure on the gases that is present in its tissue so when the fish is brought to the surface too rapidly, the high pressure is removed and the gases that were compressed in the tissue of the fish in deep sea are releases to expand that causes explode of gas-filled swim bladder. There is very high pressure in the atmosphere when we go deep into the sea which put pressure on the lungs of humans and gas-filled swim bladder of fishes which decrease its volume.

View Available Hint(s) Why are liver extracts used in the Ames test? A liver extract is necessary for the bacteria to produce histidine revertants. Liver enzymes activate the bacterial enzymes. Liver enzymes may activate some innocuous compounds, making them mutagenic. The bacteria require the nutrients present in the liver extract for growth.
Answer:
Part A: False
Part B: Liver enzymes may activate some innocuous compounds, making them mutagenic
Explanation:
The Ames test, also known as Salmonella typhimurium reverse mutation assay, is a bacterial short-term technique used to identify if a particular chemical compound may cause mutations in target cells. It has been shown that there exists a positive correlation between carcinogenicity and mutagenicity in the Ames test, but this correlation is not absolute. In the Ames test, a rat liver homogenate (containing liver enzymes) can be added in order to identify substances that are not mutagenic themselves but are metabolized in order to form a mutagen (e.g., benzopyrene).
