Why is it important for an organism to have high fitness (the ability to survive and make a lot of offspring)?
Answer:
An organism with high fitness has adaptations that are well suited to their environment allowing them survive and reproduce. An organism with low fitness has characteristics that are not well suited to their environment meaning they almost certainly die without reproducing.

What statement is true as you go deeper into the ocean? Question 5 options: As ocean depth increases, temperature increases. As ocean depth increases, temperature decreases. As ocean depth increases, density decreases,
Answer:
As ocean depth increases, temperature decreases.
Explanation:
The sun plays a big part in the temperature of the water, and the higher you are, the more impactful the sun is. When you get much deeper into the water, the sun's rays can't warm as much, so the temperature decreases.
The statement that is true when one goes deeper into the ocean is that as ocean depth increases, temperature decreases, which is a second option, as the temperature of the ocean generally decreases as one goes deeper into the ocean.
What is the relationship between depth and temperature?As one goes deeper into the ocean, less sunlight reaches the water, and the water becomes colder, the density of seawater generally increases as one goes deeper because the pressure of the water increases with depth, causing the water molecules to become more tightly packed together. Density is another property of seawater and depends on the temperature, salinity, and pressure of the water, so when one goes deeper into the ocean, the pressure increases, which causes the density of the seawater to increase.
Hence, the statement that is true when one goes deeper into the ocean is that as ocean depth increases, temperature decreases, which is a second option.

What are some of the implications of Directed Evolution?
Answer:
Adaptive laboratory evolution selects many genome-wide mutations that contribute to the fitness of actively growing cultures, whereas directed evolution typically targets a specific gene for mutagenesis and then screens the resulting variants for a phenotype of interest, often independent of fitness effects.
Explanation:
Answer:
Directed evolution is the laboratory process by which biological entities with desired traits are created through rounds of genetic diversification. It can also be created through library screening or selection and has become one of the most useful tools in basic biology. It's role includes improving the stabilities or biochemical functions of proteins by repeated rounds of mutation and selection.
More simply said, directed evolution is a mimic of the natural evolution cycle in a laboratory setting.
It has indirectly revealed that single amino acid mutations can enhance properties such as catalytic activity or stability and that adaptation can often occur through pathways consisting of beneficial mutations.

if you were asked to construct a power plant that uses only renewable energy sources, what type of energy would you use ? Explain.
In an ecosystem, a deer consumes grass. what percentage of energy will the deer acquire from the grass? 0.1% 1% 10% 100%
About 10% of energy is transferred from the grass to the deer when the deer eats the grass.
Second law of thermodynamicsThe second law of thermodynamics pertains to the conversion of energy from one form to another. According to the second law of thermodynamics, when energy is converted from one form to another, the conversion is not 100% efficient.

geologists describe the rock cycle as ' nature's recycling system' what does it mean? please help
Answer:
The Rock Cycle is Earth's great recycling process where igneous, metamorphic, and sedimentary rocks can all be derived from and form one another.Older rocks are destroyed by weathering processes and the remains are recycled into new rocks. This cycle from old rocks to new rocks is called the rock cycle. The interaction between the tectonic and the hydrologic systems causes constant recycling of the materials of the Earth's crust.

Which of the following is a major risk factor for a noninfectious disease?
A virus
A bacterium
High cholesterol
Poor hygiene
Answer: High Cholesterol
Explanation:
Got it right on my test
High cholesterol is a major risk factor for a noninfectious disease. Option C is correct.
Non-infectious diseases are not caused by germs, but rather by other factors such as genetics, lifestyle, and environmental factors. High cholesterol is a major risk factor for several non-infectious diseases, including heart disease, stroke, and peripheral artery disease.
Viruses and bacteria are examples of infectious agents that can cause infectious diseases. Poor hygiene can increase the risk of contracting an infectious disease, but it is not a major risk factor for non-infectious diseases. The risk of developing many non-infectious diseases increases with age. Some people are more genetically predisposed to developing certain non-infectious diseases than others.
