Explain the difference between the structure of a simple leaf and a compound leaf, and how such differences can be used within identification systems to determine the species of a plant.
Answer:
Explanation:
A simple leaf is a single leaf that is never divided into smaller leaflet units. It is always attached to a twig by its stem or the petiole. A compound leaf on the other hand is divided to the midrib, forming two or more distinct blades
Answer:
Simple leaves have an undivided leaf blade and there is an axillary bud at the base of the leaf. However, compound leaves have divided leaves. Thus, a compound leaf has more leaflets than a simple leaf. Furthermore, there is no axillary bud present at the base of each leaflet.

for purple and a gene for pink, what hair color will they have?
Select one:
O pink
O kind of pinkish, puplish
O purple
O they will be bald
Answer:
The answer is option 3.
Explanation:
Given that purple is dominant (similar to greater) to pink so the allele will choose purple as their phenotype (physical appearance)
2. If the climate were to change in an environment,
it is more likely that some individuals within a
population will survive if
a. the individuals stop reproducing.
b. the individuals are genetically
identical.
c. there is genetic variation within the
population
d. the individuals reproduce asexually.
Answer:
C, there is genetic variation within the population
Explanation:
When climate change occurs in an environment, it is more likely that some individuals within a population will survive if there is genetic variation within the population. So, the correct option is C.
What is Genetic variation?Genetic variation is defined as the difference in DNA between individuals or between populations where there are many sources of genetic variation including mutation and genetic recombination. Mutations are the ultimate source of genetic variation, but some other mechanisms, such as genetic drift, contribute to it as well.
Genetic variation is caused by mutations that can create completely new alleles in a population, random mating, random fertilization, and recombination between homologous chromosomes during meiosis. When climate change occurs in an environment, it is more likely that some individuals within a population will survive if there is genetic variation within the population.
Therefore, the correct option is C.

a.) pollution that comes from a source that can't be tied to a specific location
b.) pollutants that are discharged from a specific location
c.) pollutants that are found in deep water
Answer:
I think it might be B
Explanation:
nonpoint sorce polution is polution resulting from many different sources in direct contrast to the point port source pollution which results in a single source
Answer:
is A. because the pollutants that come from a source that cannot be tied to a specific location.
Nonpoint source pollution can include: Excess fertilizers, herbicides and insecticides from agricultural lands and residential areas. Oil, grease and toxic chemicals from urban runoff and energy production. Sediment from improperly managed construction sites, crop and forest lands, and eroding streambanks.

The respiratory system brings in _________ and the digestive system breaks down _____________ so that both substances are available to cells to make __________.
Answer:
Oxygen; food; adenosine triphosphate (ATP).
Explanation:
Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells, so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP).
All living organisms such as plants and animals require energy to function properly (life activities). The cell organelle where energy from nutrients are released is generally referred to as mitochondria. Animals and plants retrieve energy using mitochondria to do cellular respiration because they typically act like a digestive system by taking in nutrients, breaking them down and obtaining energy rich molecules for cell-life activities.
This ultimately implies that, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.
Generally, oxygen goes into the body of a living organism such as plants, humans and animals when they breathe (respiratory system) while glucose is absorbed by the body when they eat (digestive system).
Hence, the respiratory system brings in oxygen and the digestive system breaks down food so that both substances are available to cells to make adenosine triphosphate (ATP).
Explain in 3-4 sentences: How can a population's gene pool can change?
Answer:
The composition of a population's gene pool can change over time through evolution. This can occur by a variety of mechanisms, including mutations, natural selection, and genetic drift. The result is a gene pool that is altered to be attuned to the needs of the population's specific environment.
