Answer:
The correct answer is - Test cross.
Explanation:
A test cross is a cross that is made between an organism with an unknown dominant genotype and an organism that purebred recessive genotype for the particular trait. It determines if the unknown genotype of the individual being tested is purebred allele dominant or heterozygous for the trait.
If all offspring in F1 generation has phenotypically dominant trait then the tested organism is pure breed dominant and if half of the offsprings have the phenotypically dominant trait and half show recessive trait then the organism to be tested is heterozygous or hybrid.
Thus the aforementioned response is correct.

A white blood cell (WBC) encounters bacteria in a scrape on the knee of a child who has fallen off of his bicycle. The WBC’s job is to take the bacteria inside of itself and destroy the bacteria. If the bacteria cannot be moved across the WBC membrane, how will the WBC most likely take it in?
Answer:
The correct answer is - phagocytosis.
Explanation:
Phagocytosis is a type of endocytosis that also engulfs the solid material including microbial pathogens like bacteria and others. In immunity response macrophages, neutrophils and. immature dendritic cells are white blood cells that perform the phagocytosis process to kill the microbes and antigens.
Phagocytosis ingests and digest pathogens and develops an adaptive immune response an essential part of the innate immune system. WBC will most likely take it in through phagocytosis in the given case.

How does your model support the claim that
the Northern and Southern Hemispheres
have different seasons?
Answer:
Due to presence on opposite side of the globe.
Explanation:
My model support the claim that the Northern and Southern Hemispheres have different seasons due to present on different location on the globe. The seasons in the Northern Hemisphere are different and opposite of those in the Southern Hemisphere. Seasons occur because Earth is tilted on its axis. This tilting causes summer in one location whereas winter in other location. The Earth's tilt causes the Southern Hemisphere to lean towards the Sun during summer season of Southern Hemisphere while on the other hand, it is winter season in the Northern Hemisphere which leans away from the Sun.

g Two linked genes, (A) and (B), are separated by 18 centiMorgans. A man with genotype Aa Bb marries a woman who is aa bb. The man's father was AA BB. What is the probability that their first child will both be ab/ab
Answer:
The probability that their first child will both be ab/ab = 41%.
Explanation:
Available data:
Two linked genes (A) and (B) ⇒ 18 centiMorgans apartMan ⇒ Aa BbMan´s father ⇒ AA BBWoman ⇒ aabbThe recombination frequency is given by the distance between genes. We have to know that 1% of recombinations = 1 map unit = 1cm.
Recombination frequency = 0.18
Man: AaBb
Gametes) AB Parental
ab Parental
Ab Recombinant
aB recombinant
18 centi morgan = 18 % of recombination in total
= % aB + % Ab
= 9% aB + 9% Ab
100% - 18% = 82% of parental in total
= % of AB + % ab
= 41% AB + 41% ab
The frequency for each gamete is:
AB 41%
ab 41%
Ab 9%
aB 9%
Cross: man x woman
Parental) AaBb x aabb
Gametes) AB, Ab, aB, ab ab, ab, ab, ab
Punnett square) AB ( 41%) Ab (9%) aB (9%) ab (41%)
ab AaBb Aabb aaBb aabb
ab AaBb Aabb aaBb aabb
ab AaBb Aabb aaBb aabb
ab AaBb Aabb aaBb aabb
F1) 41% of the progeny is expected to be AaBb
9% of the progeny is expected to be Aabb
9% of the progeny is expected to be aaBb
41% of the progeny is expected to be aabb

Answer:
A single replacement reaction occurs when an element reacts with a compound to produce a new element and a new compound. It can only occur when the element that is doing the replacing is more reactive than the element that is being replaced. Therefore, it is useful to have a list of elements in order of their relative reactivities. The activity series is a list of elements in decreasing the order of reactivity. Since metals replace other metals, while nonmetals replace other nonmetals, they each have a separate activity series.
There are two types of single replacement reactions:
A metal replaces another metal that is in solution:
A + BC → B + AC
Example: Zn + CuC[tex]l_{2}[/tex] → Cu + ZnC
A halogen replaces another halogen that is in solution:
A + BC → C + BA
Example: Br[tex]_{2}[/tex] + 2KI → I

Say you had the following DNA sequence: ATGCTGCGAAACTTTGGCTGA Let's say there was a mutation that removed one letter (the first C): ATGCTGCGAAACTTTGGCTGA Provide the 6 DNA codons that would be read following the mutation. Are they the same as the original 6 DNA codons that would have been read
Answer:
Codons after the mutation are not exactly the same as before mutation, because one base was deleted, changing the sequence of codons.
Codons before mutation: ATG TGC GAA ACT TTG GCT
Only the first one (ATG) might coincide with one of the codons before mutation.
Explanation:
Genetic information for the aminoacids assembly during the protein synthesis is stored in short sequences of three nucleotides named codons in the DNI or mRNA. Each of the codons represents one of the 20 amino acids used to build the protein. There are a total of 64 codons. 61 codify amino acids, one of these amino acids is also the start point of protein synthesis, and the left three codons are stopping translation points.
The Sequence before mutation ATGCTGCGAAACTTTGGCTGA
Codons: ATG CTG CGA AAC TTT GGC TGA
The Sequence after mutation ATGTGCGAAACTTTGGCTGA
Codons: ATG TGC GAA ACT TTG GCT
Only the first one (ATG) might coincide with one of the codons before mutation.
Which process is characterized by the movement of particles from an area of high concentration to an area of low concentration across the plasma membrane without the use of energy?
1) hypertonic transport
2) active transport
3) passive transport
4) dynamic equilibrium
Answer:
3) passive transport
Explanation:
Passive transport is a type of cellular transport that does not require the use of energy to move substances (i.e., ions and molecules) across biological membranes. Passive transport uses concentration gradients to move substances across cell membranes, thereby transporting them from regions of high concentration to regions of low concentration. Passive transport can be divided into 1-osmosis (i.e., movement of solvents), 2-diffusion (i.e., movement of solutes), and 3-facilitated diffusion (i.e., movement of molecules with help of protein channels or carriers), and 4-filtration (i.e., movement of water by using a pressure gradient).
Answer: moves particles from on area of low concentration to an area of high concentration
Explanation: Active transport differs from passive transport because active transport
can only move particles into the cell.
does not require energy to transport particles.
moves particles from an area of low concentration to an area of high concentration.
depends on the random movements of particles to carry them across the membrane.

Which statement correctly compares mass and weight?
A.Both depend on the force of gravity pulling on an object B.The basic unit of both is the kilogram C.Both mass and weight ofan object would be less on the moon than on Earth D.Weight varies with location, but mass does not vary
Answer:
D. Weight varies with location, but mass does not vary
Explanation:
Weight can be defined as the force acting on a body or an object as a result of gravity.
Mathematically, the weight of an object is given by the formula;
[tex] Weight = mg [/tex]
Where;
m is the mass of the object.g is the acceleration due to gravity.Mass can be defined as a measure of the amount of matter an object or a body comprises of. The standard unit of measurement of the mass of an object or a body is kilograms.
Irrespective of the location of an object or a body at a given moment in time, the mass (amount of matter that they're made up of) is constant. This ultimately implies that, whether you're in the moon, space, earth or any other place, your mass remains the same (constant).
Hence, the statement that correctly compares mass and weight is that, weight varies with location, but mass does not vary. This is simply because acceleration due to gravity changes with location i.e its value varies with the planets.
