Explanation:
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.

anthracite coal
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)

Oxygen is essential for many forms of life, yet early earth had very little oxygen in the atmosphere. Where did the increase in oxygen come from?.
Answer:
Literally, it is the waste product of cyanobacteria, also known as blue-green algae.
EXPLANATION
Explanation:
Between two to three billion years ago, Earth's atmosphere started changing.
Organisms living then were doing so anaerobically (without oxygen), but there was a gradual build up of oxygen in the atmosphere - the reason for this, as well as for the percentage of oxygen stabilising at around 21% is still unclear.
What we do know is that tiny organisms known as cyanobacteria (or blue-green algae) would photosynthesise carbohydrates for their nutrition and growth using sunlight, water, and carbon dioxide.
The waste product of photosynthesis, till today, is oxygen.
Over time, this oxygen increased till it reached the levels that we experience today.
The chloroplasts in today's plants are symbiotic cyanobacteria that continue the same process started billions of years ago.

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.

Answer:All star smash mouth
Explanation:
All star smash mouth. A planet is a sizable body that revolves around a star.
What are planets?
An object must have enough mass to have been compressed by gravity into a spherical, or round, shape in order to qualify as a planet. It must also be big enough for any rocky or icy debris in its orbit around the star to have been swept away by gravity.
According to science, planets start to form when a nebula, or dense cloud of gas and dust, revolves around a young star.
Gravity forces the nebula's material fragments to clump together over time. These aggregates develop and gather over time. These clusters eventually develop into planets.
Therefore, All star smash mouth. A planet is a sizable body that revolves around a star.

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.
Therefore, 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.
