Why were the prokaryotes split into
two kingdoms?
A. Their size was much different from
each other
B. They were discovered to be very
different from each other
C. It makes it easier to sort out all of
the organisms
D. There were too many bacteria for
one kingdom
Prokaryotes were split into two kingdoms because they were discovered to be very different from each other.
The correct option is B.
What are prokaryptes?Any organism that lacks internal membranes, which prevents the formation of a distinct nucleus and other organelles, is referred to as a prokaryote (also written procaryote). The most well-known prokaryotic species are bacteria. Prokaryotes are different from eukaryotes because they don't have internal walls.
Separate prokaryotic kingdoms with purportedly distinct evolutionary histories are called bacteria or eubacteria and archaebacteria or archaea.

hrips are insects that feed on rose pollen. Scientists noted that the thrips population increased in the spring and decreased dramatically during the summer. The researchers hypothesized that food abundance was the limiting factor for the population. Which of the following types of data would be most useful for the scientists to collect at regular intervals on a designated test plot of rose plants?
A. Amount of sunlight (hours/day)
B. Mean temperature (°C)
C. Density of rose pollen produced (g/m2)
D. Amount of pollen produced by each flower (g/flower)
Answer: Density of rose pollen produced (g/m2)
Explanation:
The data that would be most useful for the scientists to collect at regular intervals on a designated test plot of rose plants is the density of rose pollen produced (g/m2).
It should be noted that the amount if sunlight or the mean temperature isn't the appropriate data that's useful in this case. Therefore, the correct option is D.

Plants do not take life of any kind to sustain their own lives.Plants harvest atmospheric carbon dioxide (a waste product), water and sunlight (both ubiquitous and freely available) to produce within themselves the food which nourishes them.Plants are born and die in the same place.Plants have yet to start a war, perpetrate a genocide, or kill members of their own species over disagreements about mere ideas.When plants die, they do not entertain silly notions of a Better Place, somewhere beyond the stars.please help

Light Forest
Dark Forest
1. Explain the theory of Natural Selection in your own words. How did the moth population change over time?
2. What selective pressure drove the moth population to change during the industrial revolution?
Answer:
Explanation: 2. the environment, its genetics
1. the industrial revolution, by carrying steam engines polluted the air
3. the change that they were having from parents to children in the colors, and the variation that they had
4. the moths were changing to better survive their environment
5. is the change of the wings of flying species due to pollution
6. Because there is little pollution, industrial melanism is reduced, which allows the moths to change to light colors

Melanie is asked to list the complementary base pairings of a DNA sample in her lab. What is the MOST appropriate response she can give? Group of answer choices ST, RJ, CO, DI, SE RFLP and PCR chromosomes and genes AT, CG, CG, AT, CG
Answer:
AT, CG, CG, AT, CG
Explanation:
Deoxyribonucleic acid, known as DNA, is a double-stranded molecule that constitutes the genetic information of a cell. DNA is a nucleic acid made up of monomeric units called NUCLEOTIDE. In other words, DNA is a long chain of nucleotides. The nucleotides are four bases namely; Adenine (A), Thymine (T), Cytosine (C) and Guanine (G).
In the DNA molecule, one strand made up of nucleotides is paired to another strand containing complementary nucleotides. This means that the nucleotide bases of one strand of a DNA molecule is complementary to the bases of the other strand.
In this question, Melanie is asked to list the complementary base pairings of a DNA sample in her lab. Her best response will be the following: A-T, C-G, C-G, A-T, C-G. Note that, Adenine pairs with Thymine while Guanine pairs with Cytosine.

Evan's playroom is 4 m by 3 m. The area of the room is:
o 7 m
07 m2
O 12 m
O 12 m2
Answer:
12 m^2
Explanation:
Area = length * width
A = 4m * 3m
A = 12 m^2
(Area is measured in square units)
Answer:
D. 12 m2
Explanation:
To do this problem, you need to find the area. To find the area of a rectangle, you multiply length x width. In this scenario:
4 x 3 = 12.
So, we know that the first two options are incorrect. Next, we have to look at the unit of measurement that we are needed to imply. In this case, we are using meters, which we need to square. Therefore, the answer is 12 m2.

You are touring several ecosystems, including an icy coastline in the Arctic, and a dry desert in the southwest United States. Do you predict that you will observe equal numbers of ectotherms and endotherms in all ecosystems? Explain your prediction.
Answer:
No.
Explanation:
No, we observe different number of ectotherms and endotherms in Arctic, and a dry desert ecosystems because there is difference in the temperature of both the environment. Due to difference in temperature of the external environment, the number of ectotherms and endotherms are present in that ecosystem. More number of ectoderms are present in the desert ecosystem where the ectoderms survive better than endotherms so we can say that number or population is different.

Identify the definition of biomagnification.
1.the accumulation over time of a chemical in a living organism.
2.the process of energy increasing in amount as you move up through the trophic levels in a food chain.
3.the accumulation of a chemical from food exposure that results in a concentration that is greater in higher trophic levels.
4.the process of using a microscope to inspect a living organism.
Answer:
3
Explanation:
basically biomagnification describes how toxins get in the body of a trophic level and increase over time as larger quantity of that trophic level are needed since only 10% of energy is transferred form one trophic level to the other.
8. TRUE FALSE Stimuli may include sights, sounds, tastes, and smells. plz answer thanks
Answer:
True
Explanation:
Our senses include both exteroception (stimuli that occur outside of our body) and interoception (stimuli occurring inside of our bodies). Our primary senses are considered to be sight, hearing, taste, smell, and touch
Answer:
True!
Explanation:
Stimuli is a thing or event that evokes a specific functional reaction in an organ or tissue. Like for example, you see a snake! That is using your sight. And since you see that snake, you run away.
