_______ 10. Most mutation are harmful.
Answer:
FalseFalseFalseFalseTrueTrueFalseTrueTrueFalseExplanation:
_False_1. A molecular group consisting of a sugar molecule, a phosphate group, and a nitrogenous base is a nucleic acid.
Nucleotides: subunits or monomers composed of a sugar molecule, joined with a phosphate group and a nitrogenated base. The chain or sequence of nucleotides composes the polymer. Different nucleotides joined by their extremes compose the nucleic acid: DNA or RNA.
A molecular group consisting of a sugar molecule, a phosphate group, and a nitrogenous base is a nucleotide.
_False_ 2. In a DNA molecule, a base pair would be composed of adenine and guanine.
In the DNA molecule, Adenine (Purine) always pairs with Timine (Pyrimidine), while Guanine (Purin) pairs with Cytosine. A-T pair is united by 2 hydrogen bonds, and the G-C pair is united by 3 hydrogen bonds.
In a DNA molecule, a base pair would be composed of adenine and timine, or In a DNA molecule, a base pair would be composed of cytosine and guanine.
_False_ 3. Cytosine and adenine are purines.
Nitrogenated bases that form nucleic acids correspond to purines and pyrimidines. Adenine and guanine derive from purines, while Thymine and Citocine derive from Pyrimidines.
Guanine and adenine are purines.
_False_ 4. During the replication of DNA, bonds are broken between the phosphate groups.
During the replication of DNA, bonds are broken between the hydrogen groups.
_True_ 5. RNA contains the nitrogenous base uracil.
Instead of Timine, RNA contains uracil that pairs with adenine.
_True_ 6. There are 20 different amino acids in a cell.
_False_ 7. The coded message carried by messenger RNA is translated into polypeptides at organelles called chloroplasts.
When mRNA leaves the nucleus, meets a free ribosome in the cytosol. Into this organelle, it starts the protein building. Ribosomes read the mRNA code and begin protein synthesis by adding the correct amino acid using transference RNA.
The coded message carried by messenger RNA is translated into polypeptides at organelles called ribosomes.
__True__ 8. The decoding of a messenger RNA message into a polypeptide chain is known as translation
__True__ 9. A severe mutation may lead to cell death and may have no effect on the body.
_False_ 10. Most mutation are harmful.
A mutation is a change or alteration in DNI sequences that introduce new variants. Many of these are eliminated, but most of them might succeed and be incorporated into each individual. These mutations are the ones that have been selected by natural selection, leading to evolution.
Most mutation are not harmful
Based on structure, DNA molecules are composed of nucleotides and mutations in DNA are mostly harmful.
What is DNA?DNA refers to sequences of nucleotides which contain the genetic information of organisms.
Nucleic acids are chains of nucleotides.
Nucleotides are molecular group consisting of a sugar molecule, a phosphate group and a nitrogenous base.
Four nucleotides are present in DNA and they include:
adenine guanimecytidine andthymidineIn a DNA molecule, a base pair would be composed of adenine and guanine is false because adenine bonds to thymine, while guanine bonds to cytidine
Cytosine and adenine are purines is false because cytosine is pyrimidine while adenine is a purine
During the replication of DNA, bonds are broken between the phosphate groups is false because the bonds broken are hydrogen bonds.
RNA contains the nitrogenous base uracil is true as uracil is found in RNA in place of thymine in DNA.
There are 20 different amino acids in a cell is true as these amino acids are found in proteins.
The coded message carried by messenger RNA is translated into polypeptides at organelles called chloroplasts is false because protein synthesis occurs at the ribosomes.
The decoding of a messenger RNA message into a polypeptide chain is known as translation is true.
A severe mutation may lead to cell death and may have no effect on the body is false because mutations can cause death of organisms.
Most mutation are harmful is true because only free mutations are beneficial.

To generate a knockin mouse, a scientist introduces to ES cells a construct with a mutant exon and within an adjacent intron, loxP sites flanking a neomycin resistance gene. What event will occur next?a. Crossing of heterozygous mice to a Cre-expressing strain.b. Homologous recombination between the mutant DNA and the corresponding gene in the mouse genome.c. Recombination between the loxP sites.d. Transplantation of cells into host blastocyst.
Answers
Answer:
b. Homologous recombination between the mutant DNA and the corresponding gene in the mouse genome
Explanation:
The Cre-lox recombination system is a versatile mammalian gene-editing tool used to produce site-specific recombination events in specific cell lines (e.g., embryonic stem or 'ES' cell lines) by facilitating the integration of a circular molecule in genomic DNA. This system makes use of a Cre recombinase enzyme from bacteriophage P1 that has the ability to recombine specific sequences referred to as Lox sequences. By using this system, it is possible to generate knockout mice by crossing a strain of mice expressing Cre recombinase strain with a targeted loxP-flanked (floxed) mouse strain. The generation of a floxed mouse consists of 1-generation of a targeting construct containing homologous sequences with the mouse genome and loxP sites flanking the gene sequence of interest, and 2-homologous recombination of the targeting construct with the endogenous target gene sequence in the mouse genome.

A plant with narrow leaves and shallow roots would probably be found in the desert, where there is not a lot of water. Narrow leaves help prevent water loss. Shallow roots can spread out long distances in search of water.
Answers
Answer:
No.
Explanation:
The characteristic of narrow leaves is present in desert plants but shallow roots are not present because water is not available in the upper layer of soil due to faster leaching of water. Desert plants have deep root system which helps them to extract water from the deep layers of soil. Narrow leaves prevent transpiration of water from the plant body which helps the plant to store more water inside its body and remain turgor.

A planet's gravity is related to which of the following?
mass and size
orbit
weight and density
surface area
Answers
Depending on the size, mass and density of the object, the GRAVITATIONAL force it exerts varies
xxx
The gravity of a planet is related to its mass and size. So, the correct option is (A).
What is Gravity?Gravity is a fundamental interaction caused by the mutual attraction between all things that have mass or energy. The force of gravity keeps all the planets in orbit around the Sun.
It is a property of matter where all the matter is attracted to all other matter. The more matter there is, and the closer the objects are to each other, the greater the force of attraction and unlike electricity and magnetism, which can either repel or attract, gravity always pulls things together.
The magnitude of gravity depends upon the mass of each object and the distance between the centers of the two objects along with the he weight of an object is determined by the pull of gravity on it.
Thus, the gravity of a planet is related to its mass and size. So, the correct option is (A).

Which statement best describes the relationship between an allele and a gene? hint - height has alleles of tall or short...
Answers
Answer:
See the answer below
Explanation:
A gene is made up of a pair of alleles that can be the same or different. When a gene is made up of the same allele, such gene is said to be homzygous and an individual is said to be true-breeding for that gene. When a gene is made of different alleles, such a gene is said to be heterozygous.
An allele, on the other hand, represents the alternate form of a gene. For example, height can be tall or short. Tallness represents one allele while shortness represents another allele. When the two alleles for a height are tall or short, it is homzygous, when it consists of one tall and one short allele, it is heterozygous.
Which pattem of wind flow is most likely to occur during a hot summer season in a coastal location?
А
From land to sea, toward areas of lower air pressure.
B.
From sea to land, toward areas of lower air pressure
С
From land to sea, toward areas of higher air pressure.
D
From sea to land, toward areas of higher air pressure
Answers
Answer:
B. From sea to land, toward areas of lower air pressure
Explanation:
The pattern of wind flow is most likely to occur from sea to land during a hot summer season in a coastal location due to difference of air pressure. In the summer season when the land is heated, the temperature of the air also increases and hot air rises up, as a result a region of low pressure is created at the surface. The air over the sea moves into this area of low pressure on the land. Hence, the direction of the wind is from the sea to the land during the day in summer season.
