Answer:
According to the semiconservative model, after one round of replication, every new DNA double helix would be a hybrid that consisted of one strand of old DNA bound to one strand of newly synthesized DNA. ... Each subsequent round of replication would then produce double helices with greater amounts of new DNA.
The semiconservative model, after one round of replication, every new DNA double helix would be a hybrid that consisted of one strand of old DNA bound to one strand of newly synthesized DNA. Each subsequent round of replication would then produce double helices with greater amounts of new DNA.
Why do they call it semi-conservative?This ]method is known as semi-conservative replication because two copies of the original DNA molecule are made, each copy conserving (replicating) the details from one half of the original DNA molecule.
Each copy has one actual strand and one newly-synthesized strand.
Thus, new DNA double helix would be a hybrid that consisted of one strand of old DNA bound to one strand of newly synthesized DNA.

Carbon-14 has 8 neutrons and 6 protons. When this radioisotope undergoes the radioactive decay process it becomes nitrogen-14.
The number of protons in nitrogen-14 is?
Answer:
Nº of protons = Atomic number → 7Nº of neutrons = Massic number - Atomic number → 14 - 6 = 7Explanation:
Probably, you will find it useful to know how to deduct this information for any other isotope.
To interpreter the representation of an isotope, you need to know that the symbol representing the isotopes is the same as the chemical element. The representation also includes a superior number that indicates the massic number, and an inferior number that indicates the atomic number.
Isotope representation ⇒ ⁰ X ₙ
Where
X is the element o is the massic number, which is defined as the sum of the number of protons and the number of neutrons. n is the atomic number, which is the number of protons.(Note: You can also find the O symbol as m symbol. Both represent the same massic number)
When protons, neutrons, and electrons get together to form an atom, they lose part of their mass as energy. This is why the atomic weight is slightly inferior to the sum of masses.
In the periodic table, there is only one value of atomic mass, which belongs to the media mass of isotopes pondered by their abundance in nature.
So, what you need to know is that
Nº of protons = Atomic number → nNº of neutrons = Massic number - Atomic number → o - n (or m - n)Nº of Electrons = Nº of protons = Atomic number → nCarbon-14 forms in the atmosphere, it is radioactive and unstable. When they emit an electron and an antineutrino, they become Nitrogen-14.
Isotope representation ⇒ ¹⁴ C ₆
Massic number = 14Atomic number = 6So, from this information we can assume that
Nº of protons = Atomic number → 6Nº of neutrons = Massic number - Atomic number → 14 - 6 = 8 Nº of Electrons = Nº of protons = Atomic number → 6So, from this information we can assume that
Massic number = 14Atomic number = 6The same reasoning can be used to determine the number of protons and neutrons of nitrogen-14.
Isotope representation ⇒ ¹⁴ N ₇
Massic number = 14Atomic number = 7So, from this information, we can assume that
Nº of protons = Atomic number → 7Nº of neutrons = Massic number - Atomic number → 14 - 6 = 7 Nº of Electrons = Nº of protons = Atomic number → 7

B. the water vapor exceeds an absolute humidity of 80 ppm
C. a warm front meets a cold front
D. clouds reach an altitude of 1000 ft
Answer:
A. the air becomes saturated with water vapor
Explanation:
The saturated water vapor air forms clouds ( nimbus clouds ) which hold that vapour at a low pressure
Answer:
A. The air becomes saturated with water vapor
Explanation:
Condensation happens one of two ways: Either the air is cooled to its dew point or it becomes so saturated with water vapor that it cannot hold any more water. Dew point is the temperature at which condensation happens.
Coffee growers can form coops to eliminate the middlemen and get better pricing for their crop. When these coops receive "social certification from a reputable agency, this
indicates to the consumer what? Choose the best answer.
O a. That migrating songbirds are better served by the farmer's coffee plantation
ob. That coffee beans have been grown under organic conditions.
Oc. That coffee quality is the best possible.
O d. That social equity has been improved for these farmers.
The correct answer is C. That coffee quality is the best possible.
Explanation
A cooperative is a term that refers to a society made up of several individuals who group for the common benefit of its members. These associations are organized democratically and are administered according to the agreement established by their partners. For example, in this case, the coffee producers formed a cooperative to sell their products directly to consumers and eliminate intermediaries. In addition, they were accredited with a social certification by an accredited agency, which supports their products by indicating to consumers that their coffee is of the best quality. Therefore, the correct answer is C. That coffee quality is the best possible.
Capillaries are very thin, narrow blood vessels that allow for the transfer of oxygen, carbon dioxide, and nutrients. The image shows
how normal red blood cells and sickle-shaped red blood cells flow through a capillary,
Use information in the image to describe two ways that the sickle cell gene mutation affects the ability of red blood cells to perform
their normal function
Answer:
less packaging of oxygen
Explanation:
normal RBC (red blood cells) have a large surface area for oxygen packaging due to its biconcave shape but when mutation occurs the RBC being produced by the short bones is sickle shaped reducing surface area of haemoglobin exposed, responsible for packaging oxygen so tissues don't get right amount of oxygen

A fiber reinforced composite contains e-glass fibers in an epoxy matrix. E for the glass is 72 GPa, E for the epoxy is 2.4 GPa. Find the elastic modulus of a composite that contains 5% fibers in the longitudinal direction, Ecl
Answer: hello your question is in complete below is the complete question
A fiber reinforced composite contains e-glass fibers in an epoxy matrix. E for the glass is 72 GPA, E for the epoxy is 2.4 GPa. Find the elastic modulus of a composite that contains 5% fibers in the longitudinal direction, Ecl = ViEi + EmVm? (note Vi + Vm= 1.) O 5.88 GPa O 5.66 GPa O 2.52 GPa O 6.74 GPa
answer : 5.88 GPa
Explanation:
Fiber reinforced composite containing e-glass fibers
E for the glass ( Ei ) = 72 GPa
E for the epoxy ( Em ) = 2.4 GPa
Determine the Elastic modulus of a composite containing 5% fibers
percentage of glass = 5% = Vi = 0.05
∴ percentage of epoxy = 95% ; Vm = 0.95
using the relation included in the question
Ecl = Ei Vi + Em Vm
= ( 72 * 0.05 ) + ( 2.4 * 0.95 )
= 3.6 + 2.28 = 5.88 GPa

In cats, coat color is an X-linked trait with incomplete dominance. Yellow coat is caused by the allele XT and black coat by the allele Xt. A tortoise cost is caused by the heterozygous condition. What is the correct way to represent the genotype of a male cat with a black coat
Answer:
The genotype of a black male is XtY
Explanation:
Available data:
coat color is an X-linked trait with incomplete dominance.Yellow coat is caused by the allele XTBlack coat by the allele Xt.Tortoise coat is caused by the heterozygous conditionSo,
females genotypes females phenotype
XTXT → Yellow coat XtXt → Black coat XTXt → Tortoise coatmales genotype males phenotype
XTY → Yellow coat XtY → Black coatMales only carry one X chromosome, so they can only be either black - XtY- or yellow -XTY-.
Females are the only ones that can express the tortoise coat.
The correct way to represent the genotype of a male cat with a black coat - XtY
We know that,
In cats, coat color is an X-linked trait - it means it is influenced by the X allele onlyIn cats, coat color is shows incomplete dominance - it means if corresponding alleles present together they will show an intermediate coat color.the allele XT - Yellow coatthe allele Xt - black coatXTXt (heterozygous) - tortoise coat (incomplete dominance)In X linked traits heterozygous conditions are not possible in males as they have only one X allele and the other is Y allele.So,
Female cats genotype would be:
XTXT - female cat with yellow coatXTXt - female cat with a black coatXtXt - female cat with tortoise coatMale cats genotype:
1. XtY - black coat male cat
2. XTY - yellow coat male cat.
Thus, The correct way to represent the genotype of a male cat with a black coat - XtY
