Think of one wild plant or animal species that lives near your home. Do you think that organism is native to
the local habitat? If it is, what steps could you take to protect it? If it is not, how would removing it affect
other organisms in the area?

Answers

For me it’s easier to think of native animals so think of an animal that lives by you. For me rabbits are very common were I live. Native animals are animals that could live in your back yard or somewhere near your backyard and non native animals are the animals at the zoo. You could think of either one! You could protect the habitats by usui house solar energy, picking up trash, using cars that run on battery, using sweaters when it’s cold instead of Turing on the heat, ect!

For me, deer is a very common animal in my area, as it is native to the habitat. Some things I could do to protect them is to prevent myself and others from littering, pick up trash, and fight to ban hunting on deer

Using a diagram or physical model to make a prediction about how lunar phases might be changed if the moon was hit by an asteroid
please help quick

Answers

Answer:

mak a plastik moon

Explanation:

make a plastic moon and make a bid dent

The actual effects would depend on various factors, including the size and velocity of the impacting asteroid, the angle of impact, and the specific characteristics of the Moon's surface. Also, these effects might be subtle and might require careful observation to detect changes in lunar phases.

New Crater Formation: The impact of an asteroid on the Moon's surface would create a new crater. This crater would likely disrupt the terrain and create a visible indentation on the Moon's surface.

Altered Reflectivity: Depending on the size and composition of the impacting asteroid, the reflectivity (brightness) of the impacted area could change. A significant impact might expose different layers of the Moon's surface materials, affecting how it reflects sunlight.

Changing Shadows: The new crater and any ejected materials could cast unique shadows during different lunar phases. The angle and position of these shadows might be different from what we typically observe.

Temporary Brightness: Immediately after the impact, the debris and ejected material might temporarily increase the Moon's brightness, potentially affecting its appearance during full moon phases.

Long-Term Effects: Over time, if the impact was significant, the crater and surrounding area might continue to affect the Moon's appearance during different phases, causing irregularities in the brightness and shadow patterns.

many species of animals carry an allele for albinism (lack of pigmentation). Albinos are usually pale or white in color. explain why the allele for albinism is present at la lower frequency than the allele for having pigments. what conditions would be necessary for the albino allele to be more frequent?

Answers

Answer: breeding an albino with an albino and let the babies lose and repeat

Explanation:

The allele for albinism is present at a lower frequency because it is not adaptive for most of the environments where humans live.

What is an allele?

An allele is a gene variant that confers a certain fitness to an individual depending on the environment where this organism lives.

Adaptive alleles are in high frequency because they confer an adaptive advantage.Non-adaptive alleles are present in low frequency because they do not confer an advantage.

In conclusion, the allele for albinism is present at a lower frequency because it is not adaptive.
