Caribbean reefs. Summarize your findings on a separate sheet of paper to turn in with this activity.

Answers

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.

B. because the body removes those genes immediately

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

Answers

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.

coal, oil and natural gas.

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)

Answers

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.

walked 25 hours or more per week were 63 to 69 less likely to develop diabetes than were those who walked less than 1 hour per week Regular exercise can prevent type 2 diabetesAlthough using a

particular the factors that encouraged or discouraged regular exerciseDiscussionThis study describes the experiences of inactive participants at high risk of type 2 diabetes who used a pedometer during a 6month group counseling process to promote lifestyle changes Participants saw the pedometer as a source of feedback on their exercise It provided immediate feedback on the amount of exercise in steps aerobic steps 60 steps minute kilometers walking time and calories By monitoring their walking the participants noted improvements in their physical capacity which in turn motivated them to exercise more Some participants particularly monitored the steps taken during a workday and many were surprised by the low number of steps recordedUsing the pedometer made it easier to set personal exercise goals These goals included increasing the amount of exercise exercising regularly and exercising daily Some participants tried to increase the number of steps taken per day whereas others pursued the goal of a minimum of 10000 steps daily Using the pedometer helped people exercise more regularly More active participants were motivated to further increase their exercise Participants found that achieving a certain number of steps made them want to increase their goal The pedometer motivated sedentary people to exercise moreThe pedometer was not appropriate for all Some were disappointed because of technical problems Moreover the 10000step recommendation for daily exercise was considered too difficult to achieve In these cases the pedometer did not increase motivation to exercise Several arguments can motivate inactive adults to use a pedometer First using the pedometer helps people monitor their own level of exercise easily set goals and track their progress Second to avoid negative experiences users could be taught to use the pedometer correctly Third a proportional increase in the number of steps as a personal daily goal should be discussed to avoid the disappointment of not reaching the difficult target of 10000 stepsGood instructions for using the pedometer are essential because functional errors were a barrier to its use The effects of the
