Answer:
Variations in species led to evolution. Some species have desirable traits that are beneficial to their survival. Some species have undesirable traits that are not beneficial to their survival. E.g. peppered moths are not easily seen by predators because they camouflage with the bark, black moths are easily seen by predators so they are eaten. In the example mentioned, the peppered moths have a beneficial trait, this is also known as fitness, because the organism is fit for survival, unlike the black moths. Overtime the population of black moths decreases because they are not fit for survival, therefore the black moths cannot reproduce offspring that also have black wings. However, the population of peppered moths increases, because the peppered moths are able to reproduce offspring. Those offspring inherit their parents' traits, which make them have peppered wings too.
We learned that Robert Hooke named cells from the Latin, cella, which means "small room". Do you think Mr. Hooke was observing plant or animals cells when he named them? How do you know?
Answer:
Plant cells
Explanation:
Visually, plant cells are more rectangular and organized as compared to animal cells which are more diverse in shape. I hope this can help you!

What is the phenotype of a person whith the genotype I^Ai?
Answer:
Type A
Explanation:
Mode of inheritance for blood is tricky, but type A and B are codominant, while type A and type B are dominant over O. So in this situtation
I^Ai is A because type a is dominant over o

4. Which of the following best describes how LAMARCK would explain giraffes with long necks? A. Long-necked giraffes eat more grass that short-necked giraffes, so their necks grow longer. B. Natural variation in the population produces some longer and some shorter-necked giraffes, and necked giraffes can reach food more easily C. Some giraffes have acquired longer necks by stretching to reach food and passed the trait to the D. Giraffes just started out with long necks and haven't changed.
Answer:
C. Some giraffes have acquired longer necks by stretching to reach food and passed that trait on.
Explanation:
in wetter climates plants usually have more stomata and grow faster. Suggest why
Answer:
A wetter climate slows the rate of transpiration allowing for there to be more stomata present on each leaf. Plants lose a lot of water when they open their stomata to get carbon dioxide for photosynthesis, especially in hot, dry deserts. Cacti lose less water by only opening their stomata at night.

Explanation:
Answer:
According to this theory mitochondria evolved from bacteria and somehow became incorporated into the cytoplasm.
Explanation:
i don't know which theory ur talking about but this theory is the endosymbiotic theory
How does population growth differ between developing countries and developed countries? What might account for these differences?
Answer:
Developing countries have a low life expectancy because things like water might be populated/scarce, the air may be polluted and immunisation might not be possible. But developed countries are more likely to have safe drinking water, and vaccines.

How the
immune system works, explain why injecting an
antigen from a pathogen would help our immune
system create "memory" of the infection but not
cause the disease.
Answer:
Our immune system produces antibodies against that antigen of pathogen.
Explanation:
Injecting an antigen from a pathogen would help our immune system memorize the infection and protect our body from causing of the disease because our immune system produces antibodies against that antigen so when the pathogen enters our body these antibodies attack on that and prevent them of causing infection in the body so that's why injecting an antigen has to be done from the childhood to prevent diseases.

Define the following :
-self-concept
-self motivation
-volunteer
-self-image
-Adolescents
Answer:
Self-concept is the set of ideas that make up the image that each person has about himself, that is, it is the opinion that an individual forges about himself. That sentence carries a certain value judgment. Self-concept: set of elements that a person uses to describe himself. Self-motivation is giving the reasons, the drive, the enthusiasm and the interest that provoke a specific action or a certain behavior. Volunteer is the person who, by his own choice, dedicates part of a part of his time to solidary, altruistic action, without receiving remuneration in return. The stage that comes after childhood and that ranges from puberty to the full development of the body is known as adolescence. Self-image is the value we have in relation to ourselves.
Explanation:
Self-concept: set of elements that a person uses to describe himself. The ability to motivate yourself is what is known as self-motivation. This is an important skill, as it encourages people to continue progressing even in the face of setbacks, to seize opportunities and to show commitment to what they want to achieve. Volunteer is that person who joins an organization in a free way to help altruistically in various social activities. When we speak of self-image we refer to the image that our subconscious has of ourselves. Adolescence is understood as the period of human development after childhood and before adulthood, in which the biological, sexual, social and psychological changes necessary to form a socially mature individual and physically prepared for reproduction take place.
