A major point of understanding natural selection is that not all organisms in a population get to reproduce. Consider the term fitness as used in biology. How does this term relate to natural selection?

Answers

Answer 1
Answer:

Answer:

The correct answer is: fitness relates to natural selection in how the organisms that get to survive and reproduce are the ones that are the fitter.

Explanation:

Fitness, in biology, is used to measure the reproductive success of an organism or a species.

An organism that is fitter, due to its fitness-increasing alleles given by microevolution (this is the change in allele frequencies), has more chances of reproducing and pass its alleles on to its offspring - this way, the more competent traits are the ones that keep on existing in the environment of said organism.

Answer 2
Answer:

Answer:

fitness relates to natural selection in how the organisms that get to survive and reproduce are the ones that are the fitter.

Explanation:

An organism that is fitter, due to its fitness-increasing alleles given by microevolution (this is the change in allele frequencies), has more chances of reproducing and pass its alleles on to its offspring

Answers

The correct answer for the question that is being presented above is this one: "root system; shoot system." Parts of a plant that are underground are called root system, while those above ground are called shoot system. the underground part is responsible for seeking for water and nourishment; the upper part is responsible for pollination.

Select all that apply.Select the items that have a pH level between 5 and 8.

pure water

Great Salt Lake

saliva

ammonia

Answers

Pure water is very close to a pH of 7. The Great Salt Lake (from what I've read about) can range from 8.2 to 7.7 in different areas. Saliva is between 6.5 and 7.5. And ammonia has a pH of 11.
So the items that have a pH between 5 and 8 are pure water, saliva, and possibly the Great Salt Lake.

Answer:

Pure water and Saliva

Explanation:

Pure water has a pH of about 7

Your saliva has a pH of about 6

The Great Salt Lake has a pH of about 10

Household ammonia has a pH in between 11 and 12

D. Eukarya

Answers

B. Bacteria 

 Unicellular organisms are not that complicated in terms of parts. They are not made to have a lot of systems and are very much suited to flourish in many places.       
Unicellular organisms are not seen to the naked eye. Because of this, unicellular organisms are not easily identified by a lot of predators except of their own kind.

Answer:

B. Bacteria

"Bottom-up" (or "data-driven") mechanisms are Group of answer choices A. mechanisms for which activity is primarily triggered and shaped by the incoming stimulus information.
B. the scientific process in which all claims must be rooted in well-established biological evidence.
C. the process by which researchers seek to develop new theories by paying close attention to the available data.
D. mechanisms for which activity is influenced by thoughts provided by the individual.

Answers

Final answer:

Bottom-up mechanisms in psychology refer to processes that are primarily driven by incoming stimulus information, starting from lower-level sensory data and working up to higher-level cognitive functions.

Explanation:

The 'bottom-up' or 'data-driven' mechanisms are A. mechanisms for which activity is primarily triggered and shaped by the incoming stimulus information.

This means that information processing starts with the stimuli that reaches our senses and then proceeds to the higher-level cognitive processes. In other words, we begin our perception by witnessing an event and the sensation driving our processing, rather than being directed by prior knowledge or expectation.

On numerous occasions, our brains begin to process data at very fundamental levels and then move on to more complex analytical thinking, which can be signified as bottom-up processing.

Final answer:

Bottom-up (or data-driven) mechanisms are mechanisms for which activity is primarily triggered and shaped by the incoming stimulus information. These mechanisms operate by processing sensory inputs in a sequential and incremental manner to build a higher-level representation or understanding.

Explanation:

Bottom-up (or data-driven) mechanisms are mechanisms for which activity is primarily triggered and shaped by the incoming stimulus information. These mechanisms operate by processing sensory inputs in a sequential and incremental manner to build a higher-level representation or understanding. They are commonly observed in biological systems, such as neuronal processing in the brain or sensory perception. For example, when you touch a hot object, your sensory receptors in the skin send signals to your brain, triggering a cascade of physiological responses to remove your hand from the source of heat.
