What is abiotic and biotic? Write examples of each.
The biotic factors are the living components of an ecosystem and are sorted into three groups: producers or autotrophs, consumers or heterotrophs, and decomposers or detritivores.Examples of biotic factors include any animals, plants, trees, grass, bacteria, moss, or molds that you might find in an ecosystem.
Abiotic factors come in all types and can vary among different ecosystems. For example, abiotic factors found in aquatic systems may be things like water depth, pH, sunlight, turbidity (amount of water cloudiness), salinity (salt concentration), available nutrients (nitrogen, phosphorous, etc.), and dissolved oxygen (amount of oxygen dissolved in the water). Abiotic variables found in terrestrial ecosystems can include things like rain, wind, temperature, altitude, soil, pollution, nutrients, pH, types of soil, and sunlight

How does artificial selection differ from natural selection? Choose all that apply.
O During artificial selection, the mating pairs are selected by humans, not the organisms.
O The outcomes of artificial selection are predictable.
O Artificial selection requires variety in a population.
O Artificial selection does not help a population adapt to its environment.
Answer:
All answers should be selected.
Explanation:
Artificial selection means humans select the mating pairs which makes the outcomes predictable. Variety is required because it is how humans can "customize" the traits of an organism. However, it does not help a population adapt to its environment because these traits are made for human satisfaction, not the survival of an organism.

Answer:
a- brown eyes
b- blue eyes
c- brown hair
d- widows peak
e-short arms
f- can roll tongue, long arms
g- brown eyes, brown hair
h- widows peak, short arms
i- brown eyes, can roll tongue
j- brown eyes, brown hair, no widows peak, long arms, can't roll tongue
Explanation:
So the capital letter is the dominant trait, and the lowercase letter is recessive. The capital dominant trait will always overpower the lowercase recessive trait. So the only way the recessive trait can be seen is if there are two together. So... if R is white fur and r is brown fur...
RR would show the dominant trait of white fur
Rr would show the dominant trait of white fur
rr would show the recessive trait of brown fur

The immune response consists of different components playing their role for a common goal: to rid the body of a pathogen. Create an analogy that helps explain the roles of the responses of the immune system and describe the relationship between the responses.
Answer:
In a primary immune response, naive B cells are stimulated by antigen, become activated, and differentiate into antibody-secreting cells that produce antibodies specific for the eliciting antigen.
A secondary immune response is elicited when the same antigen stimulates memory B cells, leading to the production of greater quantities of specific antibodies that are produced in the primary response

What is metabolism?
Metabolism refers to the chemical processes that occur within a living organism in order to maintain life. These processes include the conversion of food into energy and the use of that energy to power the organism's growth, reproduction, and other functions.
Metabolism can be further divided into two main categories: catabolism and anabolism.
Catabolism is the process by which the body breaks down molecules to release energy. It includes the breakdown of complex molecules such as carbohydrates, fats, and proteins into simpler molecules that can be used by the body's cells for energy. This process produces waste products such as carbon dioxide and water which are eliminated from the body.
Anabolism is the process by which the body uses energy to build molecules. It includes the synthesis of complex molecules such as proteins, nucleic acids, and polysaccharides from simpler molecules. Anabolic reactions consume energy, rather than release it, and they require precursors and enzymes.

Come up with five ethical guidelines for research. Write statements that reflect your own views of
what is right and wrong. If you really love animals, an example of one guideline might be "No
animals may be used in research of any kind." However, when coming up with these guidelines, be
thoughtful about what they really mean. Think of the information you read about earlier. Try to
phrase your guidelines in a way that would allow research that you think would be beneficial to
still be done. You may find that certain circumstances may cause you to rethink your own ethics!
