Let’s say two items which are balls, are very identical and were dropped at the same times and same height, fell at different times. The pink ball fell first while the blue one fell last. What could have caused the pink ball to fall first?
Answers
Answer:
This could mean that the pink ball had a little bit more air in it than the blue ball. They could also have been dropped at the same time, but they were dropped on a hill, and the pink one landed first at the top of the hill, and the blue one landed second at the bottom of the hill.

Which is a characteristic that distinguishes members of the
plant kingdom from members of the animal kingdom?
Select one:
A. Plants store genetic information in the nucleus of their cells
B. Plants are motile primary consumers
C. Plants are multicelular
D. Plants are autotrophic
Answers
Answer:
D. Plants are autotrophic
Explanation:
Both plants and animals are eukaryotic, meaning they contain a nucleus with genetic information, so that crosses out A. I don't know what motile primary consumers are. Assuming, they're primary consumers, primary consumers are those that eat producers, so in this case, this would elminate B. Both plants and animals are multicellular. Plants ARE autotrophic, meaning they produce their own food. Animals, however, have to get their own food, either by hunting or scavaging.In a school, small noses (S) are dominant to Big noses (b).

What traits would help a predator be more “fit” to survive in each environment?
The environments it means are a white snowy place and a darker summer place. No links
Answers
A predator would likely be more fit if he could blend in with his surroundings, made minimal noise, had good hearing, and could move quickly.
What will make a predator fit in every environment?
Not simply color, but also possibly rough skin, sharp teeth, or claws to ward off predators, could have an impact on an individual's ability to survive.Microevolution (change in allele frequencies) can result via natural selection, with fitness-increasing alleles becoming more prevalent in the population.Reproductive success is measured by physical fitness (how many offspring an organism leaves in the next generation, relative to others in the group).It is the only method of evolution that may continuously lead to populations being more acclimated to, or better suited for, their environments, throughout time.Therefore, natural selection is the phenomenon for survival of the fittest.

Determine which are true of prokaryotic and eukaryotic transcription. In prokaryotic cells _____________; in eukaryotic cells ______________.
Answers
Answer:
This question is not complete as it lacks options. However, it can be answered by giving the general differences between eukaryotic and prokaryotic transcription.
Explanation:
Eukaryotes are organisms that possess a membrane-bound nucleus that harbors their genetic material while prokaryotes are organisms that lack a membrane-bound nucleus.
Transcription is the process whereby a DNA template is used to produce an mRNA molecule. Below are the common differences in the transcription of eukaryotic and prokaryotic:
- Transcription in eukaryoric cell occurs in a NUCLEUS while transcription in prokaryotic cell takes place in a CYTOPLASM
- Transcription in eukaryotic cell requires proteins called TRANSCRIPTION FACTORS while transcription in prokaryotic cell does not require TRANSCRIPTION FACTORS.
- Transcription in eukaryotic cells occurs differently from translation while transcription in prokaryotic cells is coupled with translation i.e occur simultaneously.

Which statement describes both a positive impact and a negative impact associated with the effects of nitrogen-enhanced fertilizers?
They increase polluted runoff and damage drinking water.
They increase plant growth and damage drinking water.
They increase denitrifying bacteria and increase plant growth.
They increase both limiting resources and denitrifying bacteria.
Answers
Answer:
Option B
Explanation:
Nitrogen fertilizer runoff into the farmlands results into Eutrophication which is a form of nutrient enrichment of the water body. Because of the nutrient enrichment, the productivity of the water increases and hence the oxygen level of the water reduces thereby degrading the quality of water and adversely affecting the aquatic life in the water body
Hence, option B is correct

A person sees a ball and kicks it, in part because of actions of the nervous system. Using the parts of the nervous system listed, describe the path of nerve impulses that cause the person to (1) see the ball and (2) kick the ball.
Answers
Answer:
In the case of seeing a ball and kicking it can be expressed in the actions of the nervous system as follows:
Part 1. Eyes see the ball and send signals with the help of sensory neurons that carry this message to the spinal cord.
PArt 2. The spinal cord processes the information and sends an "impulse" of kicking the ball that will transfer to motor neurons that transfer it to the brain and then muscles.
Sensory neurons --> spinal cord --> motor neurons --> brain---->leg muscles

The advantage of selective breeding is the ability to produce offspring with more desirable traits. Therefore, option A is correct.
What is selective breeding?Choosing parents with specific traits to breed with one another in order to generate kids with more desired traits is known as selective breeding. For thousands of years, humans have carefully bred a variety of animals and plants, including crop species that produce more.
Through artificial selection, several fruits and vegetables have been enhanced or even created. For instance, selective breeding was used to create broccoli, cauliflower, and cabbage from the wild mustard plant.
