Option (a) 77
(b) 87
(c) 92
(d) 95
(e) 102
Plz answer
Answer:
its e (102)
Explanation:
so, 120*15/100
Cancelling the zeros!
so,
12*15/10
= 6*15/5
=6*3/1
First we have to find 15% of 120
=6*3
=18
So, 15% of 120 is 18
now decreasing it from 120
120-18
=102
SO THE OPTION (e) IS CORRECT

Can be specialized for specific tasks in multicellular organisms Contain DNA Contain nuclei Are surrounded by a cell membrane Were the first photosynthetic organisms on Earth Can be specialized for specific tasks in multicellular organisms
Answer:
See the answer below
Explanation:
Prokaryotic cell: contain DNA, are surrounded by a cell membrane, were the first photosynthetic organisms on earth.
Eukaryotic cells: can be specialized for specific tasks in multicellular organisms, contain DNA, contain Nuclei, are surrounded by a cell membrane.
Prokaryotic cells are the earliest cells to be formed in the pre-oxygen earth. The photosynthetic prokaryotic cells released oxygen into the atmosphere during the process of photosynthesis and as such, other forms of cells were able to evolve. Prokaryotic cells lack a nucleus and membrane-bound organelles. Their DNA lies freely within the cytoplasm but the cell itself is surrounded by a cell membrane that controls the movement of substances in and out of the cell.
The eukaryotic cells evolved much later after the prokaryotic cell. It has both nucleus and membrane-bound organelles. The DNA is located in the nucleus and the cell is also surrounded by the cell membrane. The eukaryotic cells can aggregate together to form tissues, organs, or systems for a specific task in multicellular organisms.
Answer:
Prokaryotes.
1. Have dna.
2. Were the first photosynthetic organisms on Earth
Eukaryotes.
1. Have DNA
2. Have nuclei.
3. Are surrounded by cell membrane.
4. Can be specialized for specific tasks in multicellular organisms.
Explanation:
Prokaryotes are majorly unicellular organisms that have no membrane bound nucleus or organelles. They are the first photosynthetic organisms on Earth. They lack mitochondria and endoplasmic recticulum.
Eukaryotes are multicellular organisms that have membrane bound nucleus or organelles. They lack chloroplast and they gave mitochondria and Endoplasmic recticulum.

What is the role of enzymes in the DNA replication process?
A. Enzymes read the DNA code and build a new DNA molecule from scratch.
B. Enzymes link together to form a template for a new DNA molecule to be built.
C. Enzymes split the DNA molecule into two rails and then transport corresponding nitrogenous bases to each rail.
D. Enzymes link adjacent nucleosides together, becoming an integral part of the structure of the new strands of DNA.
Answer: C. Enzymes split the DNA molecule into two rails and then transport corresponding nitrogenous bases to each rail.
Explanation: This would be known as the double helix because it is being split.
Different enzymes are involved in DNA replication: DNA polimerase, primase, helicase, ligase, and topoisomerase. The correct option is C. Enzymes split the DNA molecule into two rails and then transport corresponding nitrogenous bases to each rail.
---------------------------------------------
DNA Replication starts in some specific place named replication origin.
Helicase
This is the first enzyme that works in the replication origin. It separates the DNA into two strands allowing the replication forks to advance by unwinding the DNA. It breaks hydrogen bonds between nitrogenated bases pairs.Topoisomerase impedes the DNA double helix near the replication forks to get too coiled when the DNA is opening.
DNA polymerase III
This enzyme is responsible for DNA elongation. It is in charge of adding nucleotides to the growing chain, from 3' to 5' extremes. It includes only nucleotides that complement the original strand. They need to recognize a primer to begin.Primase is in charge of synthesizing primers.
DNA polymerase I eliminate ARN primers and substitute them with DNA.
DNA ligase seals the gaps that remain after replacing the primers.

Homologous chromosomes are chromosomes that are the same? true or false
Answer:
False
Explanation:
The 22 pairs of homologous chromosomes contain the same genes but code for different traits in their allelic forms since one was inherited from the mother and one from the father. So humans have two homologous chromosome sets in each cell, meaning humans are diploid organisms.

At very high temperatures, most enzymes do not increase the rate of the reactions they regulate. What is the most likely reason for this lack of enzyme activity at very high temperatures?
a.The enzyme denatures and can no longer function properly.
b.The enzyme would have already broken down at a much lower temperature.
c.The products would have already been used up in the reaction by the time it reaches that high temperature.
d.The enzyme would have already sped up the rate of reaction as much as it could and would not be affected by the increase in temperature.
The enzyme would have already sped up the rate of reaction as much as it could and would not be affected by the increase in temperature. Hence, option D is correct.

The diagram shows molecules that a mitochondrion and produces during a cellular process. Which other molecules is a product of this process?
A. DNA
B. RNA
C. C6H1206 (glucose)
D. ATP
Answer:D
Explanation: DNA and RNA are held in the nucleus and have nothing to do with what is shown in the image which is the process of cellular respiration. What is fascinating is that the mitochondrion has its own DNA but it does not produce it in a cellular process. C is false because the mitochondrion takes in glucose so it will go alongside the pyruvate O2. So we can conclude that it produces ATP with H2O and CO2 during this process.
ATP molecule is also a product of the cellular process that occurs in the mitochondria.
MITOCHONDRIA:
The mitochondrion is a membrane bound organelle found in eukaryotic cells. The mitochondrion is regarded as the power house of a cell because it is the site of the cellular process that synthesizes energy for the cell.The cellular process that occurs in the mitochondria is called cellular respiration. Generally, cellular respiration breaks down glucose molecule in the presence of oxygen. The chemical equation is as follows:C6H12O6 (glucose) + 6O2 (oxygen) → 6CO2 (carbon dioxide) + 6H2O (water) + ATP (energy)
From the attached image, it can be seen that water (H20) and carbon dioxide (CO2) are products. However, ATP molecules is also synthesized during this cellular process. Therefore, ATP molecule is also a product of the cellular process that occurs in the mitochondria.Learn more: https://brainly.com/question/23126016?referrer=searchResults

If the strand of DNA being used is A A A T A A G C G C C A, what is the messenger RNA strand that will be produced?
Answer: UUUAUUCGCGGU
Explanation: Remember the base pairing rules: cytosine with guanine and adenine with uracil. To compliment the given strand, you'd have to choose the base that would pair with each individual nucleotide. Since mRNA has no thymine, the adenine must pair with uracil instead. However, it does have adenine to pair with the thymine, even if it doesn't have any of its own.

White blood cells are especially active when you are sick because their primary job is to fight off infections – often bacteria or viruses that do not belong in you. Once they locate the invader making you sick, they eat it and destroy it. What organelle do you think is plentiful in white blood cells?
Answer:
Lysosomes
Explanation:
Lysosomes are membrane bound organelles that contain degradative enzymes. They degrade worn-out cellular parts and may also be used by cells to degrade/destroy invading bacteria or viruses. Hence, since white blood cells are primarily responsible for fighting infections, it is expected that they have a high amount of lysosomes (which they indeed do have in high amount).
