Answer:
The answer is A
Explanation:
b. natural selection.
c. descent with modification.
d. acquired characteristics.
Answer: Artificial selection.
Explanation: Artificial Selection can be defined as the intentional reproduction of the individuals that have the desired trait. The organism having the desired character breed together to give rise to the individual having the desired trait.
The dairy farmer choose to breed the cows that give most milk. This is the desired character that we want in the offspring.
Well, i took the test and i put artificial selection and got it right. The definition of artificial selection is "The breeding of plants and animals to produce desirable traits" So the answer is A
Answer: ENDOTOXIN
Explanation: Meningitis is a nervous system disorder that occurs when there is an infection and inflammation of the meninges,these meninges are the membranes that cover the brain and the spinal cord,they are the pia mater, dura mater,and the arachnoid mater.
This infection and inflammation of the meninges is causes by inversion of microorganism, bacteria precisely,when these bacteria that are gram negative invade the meninges,the cell wall of the bacteria dies off exposing the cellular contents, this exposure introduces a toxin known as LIPOPOLYSACCHARIDE directly in to the meninges which disrupts the normal functioning of the meninges, infection further sets in and inflammation is triggered as well.
An ant that is resistant to pesticide .
B)
A cactus that has no spines.
C)
A mouse that has learned to avoid mousetraps.
An example of an organism with a genetic variation that could improve survival chances over time would be an ant that is resistant to pesticides (Option A)
Genetic variation refers to differences in the genetic material (DNA) among individuals within a species. This can arise due to several mechanisms, including mutation, recombination, and genetic drift. Genetic variation provides the basis for evolution by natural selection, as it allows for populations to adapt to changing environments and helps to ensure the survival of the species over time.
Genetic variation can also play a role in disease resistance, as some individuals may carry genetic variations that protect them from certain diseases. Additionally, genetic variation can impact physical and behavioral traits, such as eye color, height, and intelligence.

Answer:
True
Explanation:
Because the genetic code is universal and the DNA molecule is the same for all living organisms, an organism can be genetically modified by introducing a gene from a different organism (called a transgene).
An example of this are Bt crops. Scientists isolated from a bacteria (Bacillus thuringiensis, Bt) a gene that produces a toxic protein that kills insects. Then, they modified crops such as cotton and corn by inserting this gene, and plants that express it can resist being eaten by insects (because when insects try to eat them they die due to the toxin).
B. real, inverted image
C. virtual, upright image
D. virtual, inverted image
I believe the answer is B. But not to sure.
B. hypothermia
C. reflex
D. respiration
The term best describes this process is homeostasis.
A self-regulating process by which an organism maintains a constant internal environment of their body is known as homeostasis.
The variables that are maintained during homeostasis are:
The substances that can disrupt homeostasis are:
