Answer:
Explanation:
pH is a measure of the relative amount of free hydrogen and hydroxyl ions in water. Water that has more free hydrogen ions is acidic, whereas water that has more free hydroxyl ions is basic. Since pH can be affected by chemicals in the water, pH is an important indicator of water that is changing chemically.

Answer:
False
False its faster! Hope this helps! More information here! Answer: An area going through secondary succession reaches its climax community faster because the area begins with some soil and some plant and animal species. An area that goes through primary succession, on the other hand, begins with no soil and no organisms, so reaching the climax community takes longer.

What is the importance of neutral variation in evolution?
A trait that is neutral in one environment may be advantageous in another.
It is usually removed from the population by natural selection due to its deleterious phenotypes in the environment.
A trait that is neutral will most likely be removed from the gene pool.
It will cause for a population to risk decline and extinction.
Answer:
A trait that is neutral in one environment may be advantageous in another.
Explanation:
Neutral variation refers to the variation (either genetic or phenotypic variation) which is unaffected by natural selection. Neutral variation is known to increase genetic variation, which is a prerequisite to evolutionary change. An allele may be neutral in one environment and beneficial (or deleterious) in another. In consequence, neutral variation in one environment may increase the response to selection in different environmental conditions.
The dew point is the point at which the
water vapor beings to fall out of the air?
True or
False
Answer:
The dew point is the temperature when water will start to condense out of the air. When air is saturated as much as possible with water vapor it is at the dew point. Air that is holding less vapor than it actually could is below the dew point

Why do you think analogous structures would cause Evolutionary biologists problems when trying to determine the relatedness of certain species?
Answer: Two analogous structures are similar in phenotype and developed to perform the same function, despite not being inherited from a common ancestor. As so unrelated species may look related due to having analogous structures.
Explanation:
Analogous structures evolved due to Convergent evolution. It means that structures are similar in functions but differ in morphology.
What do you mean by Species?A biological species is a group of organisms that can reproduce with one another in nature and produce fertile offspring.
Analogous structures are similar in structure that evolved independently in two living organisms to serve the same purpose. Due to their approx similarity sometimes evolutionary biologists face problems when trying to determine the genetic relatedness of certain species.
Therefore, Analogous structures evolved due to Convergent evolution. It means that structures are similar in functions but differ in morphology.

Cottontail rabbits closely resemble the fall and winter plants in which they hide
Answer:
In earlier generations, the rabbits that looked most like their surroundings survived and reproduced.
Explanation:
The cotton-tailed rabbits consist of 20 species that are found in America and have stubby tales with white under them. They're distributed over north, central, and southern America. They live in nests called forms, have an average life span of 2 years. Due to their camaflugeous nature, they change their coat color twice every year to protect themselves from predators.What does Sach see in the plant cells when he views them through the “new” microscope?

Answer:
5= mRNA is “messenger” RNA. mRNA is synthesized in the nucleus using the nucleotide sequence of DNA as a template. This process requires nucleotide triphosphates as substrates and is catalyzed by the enzyme RNA polymerase II. The process of making mRNA from DNA is called transcription, and it occurs in the nucleus.

Which statement about the effects of natural events and human activities is true?
A.The environment is not usually affected by natural events
B.Human activities and natural events can damage the environment.,
C.Natural events always have a positive impact on the environment.,
D.All human activities change the environment in a negative way.
Answer:
B. Human activities and natural events can damage the environment.,
Explanation:
Human activities are those activities carried out by a human being. The environment is being degraded daily as a result of the activities of man as well as natural occurrences e.g earthquake, tsunami, wild fire etc.
Human activities also called anthropogenic activities that damage the environment include sewage pollution, burning of fossil fuels, oil spillage etc. Hence, according to this question, human activities and natural events can damage the environment.

difference between parallel venation and reticulate venation
this is where you can get
The difference between parallel venation and reticulate venation is in parallel venation, the vein of the leaf blade is in a parallel pattern, and in reticulate the vein of the leaf blade is a net or web-like structure.
What is venation?Venation is the pattern of veins present in the leaves. There are different patterns of veins present in the leaves, parallel venation, for example, banana leaf, and reticulate venation, for example, papaya leaf.
Thus, In contrast to reticulate venation, where the vein of the leaf blade is arranged in a net-like pattern, parallel venation has the vein of the leaf blade arranged in a parallel pattern.
