1. Unlike animal cells, plant cells contain A. a nucleus B. chloroplasts c. mitochondria
Answers
Answer:
Chloroplasts
Explanation:
Chloroplasts makes photosynthesis
Nucleus stores the DNA
Mitochondria produces energy
Unlike animal cells, Plant cells contain chloroplasts. Option B is correct.
Unlike animal cells, plant cells contain chloroplasts. Chloroplasts are organelles found in plant cells that are responsible for photosynthesis. They contain a green pigment called chlorophyll, which captures sunlight and converts it into energy for the cell. This process allows plants to produce their own food.
Animal cells, on the other hand, do not contain chloroplasts. Instead, animal cells obtain energy through other organelles called mitochondria. Mitochondria are often referred to as the "powerhouses" of the cell because they generate energy in the form of ATP through cellular respiration.
So, while both animal and plant cells contain a nucleus and mitochondria, only plant cells contain chloroplasts. option B is correct.

Summarize the roles of glycolysis, citric acid cycle, and the electron transport chain in energy generation. (in 2-3 sentences please) :)
Answers
Answer:
Glycolysis is a series of reactions that take place in the cell cytoplasm. It involves the oxidation of glucose into pyruvate (a 3 carbon compound), that produces (overall)ATP and reduced NAD: an enzyme that carries hydrogen. The number of carbons in each of these compounds is indicated in the green circle.
The carriers FAD and NAD bring the hydrogen and it separates to H+ and electrons (e-). The electrons pass from carrier to carrier and loose energy. This is used to synthesize ATP.
However, there are a lot of hydrogen ions, that unless they are removed, they'll cause a large increase in pH. Therefore, oxygen reacts with the ions to remove it and produce water. This is what the oxygen you inhale is used for (in terms of respiration).

is equal to A. The addition is represented below. (Note
that the variables are used to represent individual digits;
no mu
ltiplication is
taking place).
AB + B
A= 1A2
What
is B?
Answers
Answer:
9
Explanation:
Another way to represent this question is:
+ AB BA1A2
In the one's column, B and A add to produce a number with a two in the one's place. In the ten's column, we can see that a one must carry in order to get a digit in the hundred's place. Together, we can combine these deductions to see that the sum of A and B must be twelve (a one in the ten's place and a two in the one's place).
In the one's column: B+A=12
The one carries to the ten's column.
In the ten's column: (1)+A+B=(1)+12=13
The three goes into the answer and the one carries to the hundred's place. The final answer is 132. From this, we can see that A=3 because 1A2=132.
Using this information, we can solve for B.
A+B=12 and A=3
3+B=12
B=9

_____________________________________Eukaryotes:Eukaryotes are those organism which have the DNA inside the nucleus surrounded by the nuclear membrane. They have all the membrane bound organelles and they have complex cell.
_____________________________________RNA TRANSCRIPTION:Transcription is the first step of gene expression (process by which the instructions in our DNA are converted into a functional product, such as a protein), in which a particular segment of DNA is replicated into a messenger RNA (mRNA) by using the RNA Polymerase as an enzyme. So the information that was in that segment of DNA is now transferred or copied into the mRNA. Both DNA and RNA are the nucleic acids, and the nucleic acids use the nucleotides as its base.
RNA TRANSLATION:When mRNA is formed, it moves out from the nucleus and attaches it self to the ribosomes. The ribosome is the main hub for the protein synthesis thus called protein factory. The ribosomes have two types of RNA, Transfer RNA (tRNA) and Ribosomal RNA (rRNA).
mRNA basically works as a INSTRUCTOR and tell the ribosome what kind of protein is supposed to be made.
tRNA works as a little boy who does all the errands so it does the grocery for the making of that PROTEIN. The grocery basically include the amino acids which are present in the cytoplasm, and the list for what amino acids are needed is given by mRNA (THE INSTRUCTOR).
rRNA works as a cook, it makes the PROTEIN. It forms the major part of the ribosomal subunits.
After the hard work of the rRNA and all the other types of RNA. THE PROTEIN IS FORMED.

Explanation: i just did the quiz on k12 :) and i put answers to all the questions if u go serch it up on brainly
In the table below, all organisms have the same four nitrogenous bases in common with each other. The correct option is d.
What are nitrogenous bases?The DNA sequence is the sequence or pairing of DNA bases. RNA and DNA both are genetic materials and both are made up of nucleic acids made up of deoxyribose acid and iron is made up of ribonucleic acid.
DNA and RNA both contain four bases that are joined with hydrogen bond RNA contain uracil in the place of thymine and DNA contain timing all other bases are the same.
The base pairs are complementary to each other: Thymine: Adenine and cytosine: guanine. But in RNA, it is uracil with adenine. Guanine and cytosine are the same.
Therefore, the correct option is d. The same four nitrogenous bases are in common with each other.

What environmental stimulus is most likely to result in a more rapid heartbeat in an animal?
Answers
Answer:
This question is incomplete, the options are:
A) Decreased temperature
B) Strong southerly winds
C) Presence of a predator
D) Lack of water
The answer is C
Explanation:
A stimulus is something that provokes a response or reaction in a living organism. It can either be internal or external. An animal can respond to stimulus such as hunger, heat, predator etc.
However, among all the listed stimuli in the options, the PRESENCE OF A PREDATOR is most likely to result in a more rapid heartbeat in an animal. This is because the predator stimulus will require the animal to respond by running in order to survive. Running will increase its metabolic activity and cause its heartbeat to increase.

The clade of organisms characterized as containing many extremophilic microbes is archea. The correct option is A.
What are archaea?A class of microbes known as archaea is related to yet evolutionary separate from bacteria. Numerous archaea have been discovered to survive in harsh conditions, such as high pressures, salt concentrations, or temperatures.
Extremophiles are the name given to these kinds of creatures. Single-celled microbes called archaea have a similar structure to bacteria. They make up the third domain of life and are unique from bacteria and eukaryotes in terms of evolution. Archaea are obligate anaerobes that exist in low-oxygen settings (e.g., water, soil).
