Answer:
b. multiple copies of the dna sample are made
Explanation:
Polymerase chain reaction (PCR) is a method used to make millions to billions of copies i.e. complete copies or partial copies of a specific DNA sample, allowing scientists to take a very small sample of DNA and amplify it. The new fragments of DNA that are synthesize during Polymerase chain reaction (PCR) also serve as templates to which the DNA polymerase enzyme can attach and start making DNA. The result of this attachment in a production of huge number of copies of the specific DNA segment in a short period of time.
Atoms are the most basic unit of matter. Two or more atoms from the same or different elements can combine to form molecules.
Cells are the most basic unit of life. Cells are made up of many different types of molecules. Which of the following accurately shows higher levels of organization within organisms, from least complex to most complex?
A. cells → organs → organ systems → tissues → organism
B. cells → tissues → organs → organ systems → organism
C. cells → organ systems → organs → tissues → organism
D. cells → organs → tissues → organ systems → organism
Answer:
B
Explanation:
Because cells make tissues which then combine to make organs which then further combine to form system
Which makes organisms like me and you
Answer: B
(An atom is the smallest unit of matter that retains all of the chemical properties of an element. Atoms combine to form molecules, which then interact to form solids, gases, or liquids. For example, water is composed of hydrogen and oxygen atoms that have combined to form water molecules.)

Answer: Clastic sedimentary rocks are made up of pieces (clasts) of pre-existing rocks. Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped. If the sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock.
Explanation:
A key part of the Watson-Crick model came when Watson realized
that adenine could form hydrogen bonds with thymine and guanine
could form hydrogen bonds with cytosine. This explains why A=T
and G C in Chargaff's rules. Also, these two hydrogen-bonded
nucleotide pairs had the exact same width, so they could form the
rungs of the DNA ladder.
The fact that these pairs could match up only in this way meant that
the sequence of bases in one strand could determine the sequence
of bases in a second strand created from the first. The second strand
is said to be complementary to the first strand. Individual bases are
paired so that the identity of any base determines the identity of the
base paired with it; that is, the complementary base.
This table lists the base abbreviations for bases in a sample of single-
stranded DNA. Fill in the second column with the base abbreviations
that are complementary to the given bases.

A–T
G–C

Explanation:
A always pairs up with T
C always pairs up with G
A - TT - AT - AC - GA - TG - CG-CC - GT - AA - TA usually pairs up with TC usually pairs up with GThese are bases of amino acids called nucleotides sequences. And this helps in the bond of several base pairs to their nucleotide sequence.What is the Watson-Crick model?
In “A Structure of Deoxyribose Nucleic Acid,” Watson and Crick defined DNA as a double helix that contained long, helical strands wound together. In their model, every DNA strand contained personal devices referred to as bases, and the bases alongside one DNA strand matched the bases alongside the opposite DNA strand.
Thus it is clear that the above answer is well explained.

Organisms of either extreme characteristic dying out while organisms with the medium characteristic have a higher fitness is identified as?
Answer: Stabilization selection
Explanation:
Natural selection involves the differential survival and growth of organisms which have suitable traits to survive in unfavorable or adverse environment. Such traits are passed on to the next generation. Stabilization selection is a type of natural selection in which the nature selects the non-extreme phenotypic traits. Middle traits are selected and such organisms grow and reproduce. Example can be given that of human babies in which babies with low weight lose more heat and babies with high weight are difficult to be delivered from the pelvis. Therefore, babies with middle weight are expected to survive more than that of low or middle weight.

.A jogger with a mass of 81.6 kg is moving at 2.2 m/s. What is the jogger's
kinetic energy
Answer:
89.6Joules
Explanation:
Kinetic energy is 1/2MV^2
Where m is Mass and v is velocity.
M=81.6 v=2.2m/s
K.E= 1/2 × 81.6 × 2.2
= 81.6 ×1.1
K.E=89.6 Joules

what is the botanical name of milk
Answer:
Milk of magnesium's scientific name is magnesium hydroxide, and the scientific name for milk of sulfur is precipitated sulfur.
The botanical name of milk is not applicable, as it is not a plant or a plant product. Botanical name is the scientific name given to plants, fungus and algae.
Milk is a nutrient-rich fluid produced by mammals. It is frequently consumed as a source of nutrients and is renowned for having a lot of calcium. Water, lipids, proteins, carbs, vitamins, and minerals are all present in milk in complicated proportions.
There is no particular botanical name for milk in the field of biology, which is the study of plants and their categorization. Different plant species are identified and categorized using botanical names.
Milk lacks a botanical name since it is a byproduct of animals, not plants.

what is the meaning of
•molecule
•compound
•atom
•element
•organic compound
•inorganic compound
Molecule: a molecule is the smallest particle in a chemical element or compound that has the chemical properties of that element or compound. Molecules are made up of two or more atoms that are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons among said atoms. Although oxygen is an element, it naturally has 2 atoms (O2), because it is a halogen and in order to reach 8 valence electrons and become stable and unreactive, it bonds with another oxygen atom. This means that oxygen atoms and oxygen molecules are different; one is an element, the other is a molecule.
Pure Substance: can be divided into two sub-categories: compounds and elements.
Compound: A chemical compound is a chemical substance composed of many identical molecules composed of atoms from more than one element held together by chemical bonds. A molecule consisting of atoms of only one element is therefore not a compound, meaning that oxygen molecules (O2) are NOT compounds. NaCl, or table salt, is.
Atom: An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms.
Element: An element is a pure substance consisting only of atoms that all have the same numbers of protons in their atomic nuclei. Elements are the base, more "pure" of the pure substances. Each element is assigned a symbol. Perhaps the most recognizable of them is H, for hydrogen.
Organic Compounds: organic compounds are generally any chemical compounds that contain carbon-hydrogen bonds. The study of these is called organic chemistry. I mean, carbon is the basis of ALL known life.
Inorganic Compounds: They are any substance in which two or more chemical elements (usually other than carbon) are combined, nearly always in definite proportions. Compounds of carbon are classified as organic when carbon is bound to hydrogen. THE OPPOSITE OF ORGANIC COMPOUNDS.

Camouflage is the use of any combination of materials, coloration, or illumination for concealment, either by making animals or objects hard to see, or by disguising them as something else. Examples include the leopard's spotted coat, the battledress of a modern soldier, and the leaf-mimic katydid's wings.Name three reasons why the atmosphere is important to life on earth and explain your reasoning.
The atmosphere ensures that all living things can carry out daily processes that are vital to survival, such as breathing. Photosynthesis, for example, could not be possible without an atmosphere, because all of the gasses in our atmosphere stay there due to Earth's gravity.
The atmosphere is vital because it plays a role in the water cycle as well, allowing rain to keep falling and giving life-giving water to organisms that need it.
Life would not be possible without an atmosphere on this planet, along with other vital things, like gravity, sunlight, and water.
