Answer:
Scanning electron microscope.
Explanation:
We can answer this question by process of elimination.
A dissection and compound light microscope have too small magnification for this question. Transmission electron microscopes allow the electrons to pass through the subject, visualizing the inside, while scanning electron microscopes capture the exterior (or as the problem worded it, the surface). Therefore, scanning electron is the right answer.

On your own: Click Return to original settings and Restart. Investigate the effects of agriculture on
Caribbean reefs. Summarize your findings on a separate sheet of paper to turn in with this activity.
Agriculture negatively affects reef ecosystems because the soil and the sea have a direct interaction of substances and minerals that can be altered with the intensification of agriculture.
What is agriculture?Agriculture is a human activity that is based on planting seeds in the ground so that they develop and form plants that have uses such as food or others.
This is one of the oldest activities of humanity and has allowed communities to develop and create trading systems, wooden constructions, navigation, among others.
What impact does agriculture have on the reefs?Agriculture generally takes place in coastal areas or near rivers because the composition of the soil must have certain minerals necessary for plants to grow.
Additionally, the components of the soil go underground to the sea and provide the water with different substances that contribute to marine life. However, the use of pesticides and other agricultural chemicals could reach the sea through runoff and affect the reefs.

Why are unsuccessful genes eventually
lost?
A. because the body alters them into more desirable
genes
B. because the body removes those genes immediately
after they are created
C. because the organisms with those genes are more
likely to die before they can reproduce
D. because the organisms with those genes will choose
not to pass them on to their offspring
Unsuccessful genes are not favored by natural selection, so they do not get lost through generations. Option D. because the organisms with those genes will choose not to pass them on to their offspring.
What is Natural Selection?
Natural selection is an evolutive force that selects beneficial alleles and increases their frequency in the population.
It acts favoring an allele or against it, according to how it affects the fitness of individuals.
Natural selection acts on variation caused by mutations. Let us remember that a mutation is a change or alteration in DNI sequences that introduce new variants.
Many of these are eliminated, but some of them might succeed and be incorporated into each individual. These mutations are the ones that have been selected by natural selection.
Unsuccessful genes are not favored by natural selection, so they do not get set. Instead, they are lost. Their frequency decreases until they dissappear. This is because they are not transmitted to the following generations.
The correct option is D. because the organisms with those genes will choose not to pass them on to their offspring.

According to Gordon Allport, __________ traits are common personality traits found in most people.
A.
primary
B.
central
C.
cardinal
D.
secondary
According to Gordon Allport, central traits are common personality traits found in most people.Therefore, the correct option is B.
What are central traits?Central traits are the core traits that define a person's personality, and they are the most useful for describing an individual's overall character. Allport believed that central traits are relatively stable and consistent over time and across different situations, and that they can have a powerful influence on an individual's behavior and attitudes.
In contrast, primary traits are more specific and less influential, while cardinal traits are rare and dominate an individual's entire personality. Secondary traits are less important and less enduring than central traits, and they are typically related to specific situations or contexts.Therefore, the correct option is B.

Explanation:
You are dealing with a problem in which the male parent has a genotype of DDmm, while the female parent has DdMm. After doing the FOIL method, what are the four sets of alleles for each parent?
The sets of alleles for each parent are Dm for the mother and DM, Dm, dM, and dm for the father. This information is fundamental for estimating genotype and allele frequencies in offspring.
What are alleles?Alleles are gene variants for a given gene locus, diploid organisms inherit two alleles for each locus (one from each parent).
Gametes are germinal (haploid) cells that carry specific allele combinations.
The analysis of gamete combinations is fundamental to estimate genotypes and allele frequencies.

Given what we know, we can confirm that a disease that harms the roots of a plant will not allow the plant to draw in water, which it needs to maintain all basic functions of life.
What do the roots of plants do?The roots of plants are the means through which they absorb water and nutrients from the soil. Without their roots, plants cannot take in water to allow for all of the most basic functions of life, and cannot survive.

these layers were buried under sand, silt, and rock. Pressure and heat changed some of this carbon and hydrogen-rich material into coal, some into oil (petroleum), and some into natural gas. (Info U.S. Energy Information)
Advantages:
Readily available (at the moment)
Relatively easy to produce energy from them
Disadvantages:
Non-renewable source – will eventually run out
Increasing fuel costs
Release carbon dioxide (CO 2 ) when burnt – greenhouse gas
Explanation: Similarities: they are both formed from organic remains and both form under enormous pressures in a sedimentary sequence. Differences: coal is formed from land-based plants in bogs and coastal swamps, while oil and gas are derived from tiny marine organisms, such as algae and phytoplankton. (https://socratic.org)
