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.

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.

Answer:
A) Identify the Dependent and Independent variables
The Independent variable is Temperature.
The Dependent variable is the seeds. The dependent variable is the variable that is being studied.
B) Calculate the average height of the seedlings in tube C.
To find the average, you must add up all of the heights and divide by the number of seedlings.
3.4 + 4.5 + 2.5 + 3.7 + 2.8 + 4.4 + 4.3 + 2.9 + 2.1 + 3.7 = 34.3
34.3 ÷ 10 = 3.43 cm
C) Conclusion
The seedlings in tube C grew much taller than the seedlings in tubes A and B.
This means that seedlings germinate better in warmer temperatures.
D) Why does Temperature affect Germination?
The temperature of the climate affects the dampness of the cotton wool. Moisture is key to germinating seeds. Seeds like a moist but not soggy environment caused by the correct temperature.
E) How could the experiment be better controlled?
The light levels in this experiment varied, but were not accounted for in the calculations.
It would have been better to keep them all under the same amount of light in order to keep the experiment accurate.

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.

cuáles son las características adaptativas que favorecen la sobrevivencia de los pingüinos?
Answer:
Los pingüinos tienen una cola corta y rígida. Pueden inclinarse hacia atrás y mantener el equilibrio sobre los talones y la cola. Esto reduce la pérdida de calor de los pies al suelo. El color del cuerpo de un pingüino ayuda a camuflarlo cuando nada.
Explanation:
Penguins have a short stiff tail. They can lean backwards and balance on their heels and their tail. This reduces heat loss from their feet to the ground. The color of a penguin's body helps to camouflage it when it is swimming.

DNA contains instructions for making the different molecules, such as proteins, that a cell needs to grow and function. To use these instructions, the DNA must first be _______ into _______.
A.
translated; amino acids
B.
translated; mRNA
C.
transcribed, mRNA
D.
transcribed; amino acids
Answer:
C. transcribed, mRNA
Explanation:
DNA, also known as deoxyribonucleic acid, is a molecule that holds genetic information needed to make other molecules in living organisms. However, before this genetic information can be harnessed, it needs to be expressed via two processes called transcription and translation.
Transcription is the first of the two processes that take place during genetic expression. It involves the synthesis of mRNA molecule from a DNA template. In other words, the DNA must first be TRANSCRIBED into mRNA.
