The only difference in the chemical structure of DNA between various organisms is---
the number of nucleotides present
the order of base pairs
the variety of bases
the number of bases in a codon
Answer: the order of base pairs
Explanation: i took this quiz lol
l
The only difference in the chemical structure of DNA between various organisms is the order of base pairs that is present in the second option. The order of base pairs is different in different organisms.
What is the base-pair role present in the DNA?There are two DNA strands in double-helical DNA that are linked together by hydrogen bonds, such as adenine's double hydrogen bond with thymine and guanine's triple bond with cytosine. All the organisms that belong to different species have the same bases and same nucleotides, such as ATP, GTP, CTP, and TTP, but the base pair order is different, and that makes them unique. The gene having some specific sequences in an animal is different from the gene of another animal, and this is due to the various base pairs in the DNA.
Hence, the only difference in the chemical structure of DNA between various organisms is the order of base pairs that is present in the second option.

Plant and animal cells have many organelles in common such as the cell membrane. However, the function of the cell membrane differs between the plant and the animal cell. Which best describes how the function of the cell membrane differs in plant and animal cells?
A. In animal cells, the cell membrane is the outermost layer of the cell, while in plant cells, the cell membrane separates the cell wall from everything inside the cell.
B. In plant cells, the cell membrane is the outermost layer of the cell, while in animal cells, the cell membrane separates the cell wall from everything inside the cell.
C. In animal cells, the cell membrane controls what comes in and out of the cell, while in plant cells, the cell membrane houses all the genetic material.
D. In plant cells, the cell membrane is made of a gel-like material that is green, while in animal cells, the cell membrane is made of a gel-like material that is red.
In plant cells, the cell membrane is the outermost layer of the cell, while in animal cells, the cell membrane separates the cell wall from everything inside the cell. Thus option B is correct.
What are the function of plant cell wall ?
Plant Cell wall is composed of cellulose which is a sugar which is a rigid structure that provides support and protection to the plant cell from any external damage.
Mechanical strength can be provided due to the presence of skeletal framework in cellulosic microfibrils.
The various shapes of plant cell due to cell wall, the additional wall component include pectin and/or lignin
Growth of plant cell can also depends on the elastic and plastic nature of cell walls.
The transport of intracellular substances between plant cells can be done by cell wall.
It occurs in two ways such as apoplastic and symplastic transport.

How does the moon cause tides?
The pull of the moon on Earth causes the water level on the shores to fluctuate.
The moon's gravitational pull acts on Earth.
The moon dries up Earth during different times of the month.
As the moon's gravity pulls on Earth, the ocean water is pulled toward it.
The moon pushes down on Earth and causes the water to rise.
Answer: 1, 4, 5
Explanation:
The moon always pulls on the tides, and in certain moments like the equinoxes the moon will set a patterned tide for the rest of the month, since the moon is being flung around in earths orbit, its gravity causes it to pull on the most flucuate object on earth: water. And if you have glass of water then put your hand into it you will see how your hand displaces the water.!
Four students were asked to classify the activities of the people in the picture below as examples of either potential or kinetic energy.
Which student correctly classified the activities? Hurry!!!!!!!!!
Hi there!
[tex]\large\boxed{\text{The first choice.}}[/tex]
Kinetic Energy (1/2 · mass · velocity²) occurs when an object is in motion, or a force is occurring on the object. An example would be a car in motion.
Potential energy (mass · height · gravity ) is obtained when an object has the ability to do work. An example would be an object on a shelf. It has the potential to fall, and this would cause the potential energy to become converted into kinetic energy.
-----------------------------------------------------------------------------------------------------------
Looking at the examples in the table, we can sort them as such:
Girl swimming laps- Kinetic energy because the girl is in motion.
Boy on diving board - Potential energy because the boy is not in motion, but has the potential to be in motion.
Girl hitting volleyball - Kinetic energy because the volleyball is in motion.
Boy holding volleyball- Potential energy because the volleyball is stationary and has the potential to be in motion.
Therefore, the correct table is table 1.
7. Which of the following statements is not
true of enzyme behavior? (pp.78–79)
a. Enzyme shape may change during
catalysis.
b. The active site of an enzyme orients its
substrate molecules, thereby facilitating
interaction of their reactive parts.
c. All enzymes have an active site where
substrates are temporarily bound.
d. An individual enzyme can catalyze a
wide variety of different reactions.
Answer:
c
Explanation:
The statement which is not true about enzyme behavior is that all enzymes have an active site where substrates are temporarily bound.
Enzymes are proteins that can act as biological catalysts by increasing the rate of chemical reactions. The molecules upon which enzymes may act are known as substrates, and the enzyme which converts the substrates into different molecules are known as products. Almost all metabolic processes which take place in the cell need enzyme catalysis in order to occur at rates fast enough to sustain life.
Metabolic pathways depend upon the enzymes to catalyze individual steps. The study of enzymes is called as enzymology and the field of pseudoenzyme analysis recognizes that during evolution, some enzymes have lost the ability to carry out biological catalysis, which is often reflected in their amino acid sequences and thus have unusual 'pseudocatalytic' properties.
Thus, statement which is not true about enzyme behavior is C.

Scientist observed an organism X and noted down the mode of nutrition as follows X secretes enzymes outside its body and digests food with these enzymes. It then absorbs the digested food. Which organism was observed by the scientist?
Answer:
Hydra
Explanation:
The mode of nutrition being described in this question is EXTRACELLULAR DIGESTION, in which a food substance is chemically broken down externally. The organisms being portrayed is HYDRA. Hydra is an animal that secretes digestive enzymes that work on the food extracellularly (outside the organism), then absorb the digested food.
Therefore, the organism X observed by the scientist whose mode of nutrition is to secrete enzymes outside its body and digests food with these enzymes, then absorbs the digested food is the HYDRA.

Question 7 of 10 What is the product of meiosis |I? O
A. Four haploid cells
B. Two diploid cells
C. Two haploid cells
D. Four diploid cells
Answer:
A. Four haploid cells
Explanation:
In this division, the secondary spermatocytes and oocytes, which contain 23 chromosomes each and are diploid in the amount of DNA, are divided into two cells, each of which will have 23 chromosomes, but twice the amount of DNA, since in anaphase there was a separation chromosome to sister chromosomes, reducing the amount of DNA by half.
As a result of this division in males in the process of spermatogenesis from the initial, diploid spermatogonia or primary spermatocytes, 4 cells are formed - spermatids that have a haploid number of chromosomes and twice less DNA than the cells from which they were formed.

2 haploid cells

Which lines are parallel if mZ1+ m2 2 = 180? Justify your answer.
A. j || k by the converse of the Same-Side Interior Angles Theorem.
B. i || k by the converse of the Alternate Interior Angles Theorem.
C. g || h by the converse of the Alternate Interior Angles Theorem.
o
D. g || h by the converse of the Same-Side Interior Angles Theorem.
Answer is choice A) j || k by the Converse of the Same Side Interior Angles Theorem
Lines j and k are the upward slanted lines on the left and right respectively. The transversal we only care about is line k. Line g is extra info put in there most likely to throw you off.
------------------------------------------------------
The Same Side Interior Angles Theorem says that if two lines are parallel, then the same side interior angles (formed by the transversal cut) are supplementary. Those two same side interior angles add to 180 degrees. The converse reverses the direction of the theorem.
The converse says that if we know the same side interior angles are supplementary, then it leads to the two parallel looking lines to actually being parallel. So this is one way to check parallel-ness of two lines.
Lines j and k are parallel if mZ1+ m2 2 = 180 by the converse of the Same-Side Interior Angles Theorem. Therefore, the correct option is option A.
No matter how far they are extended, parallel lines are two or more lines that exist in the same plane and never cross. In other words, they will move in the same direction and stay a fixed distance apart from one another over their whole lengths. One side of an intersecting line with parallel lines has a total interior angle of 180 degrees. One line, h, crosses the lines j and k in this instance. Also the interior angles in one side are 1 and 2. Here angle 1 +angle 2= 180 degree. Thus j and k lines are parallel.
Therefore, the correct option is option A.
