Answer:
DNA rearrangment.
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
The human somatic cell is made up of 46 chromosomes which are sub-divided into 22 pairs of autosomes and a pair of sex chromosomes (X and Y). An autosome is one of the numbered chromosome that is typically not a sex chromosome.
On the other hand, sex chromosomes (X and Y) are responsible for determining the gender or sex of living organisms such as humans.
Deoxyribonucleic acid (DNA) is an organic complex-molecular structure found in all living organisms. It comprises of genes and is essentially the foundation block of all living organisms such as humans, animals and plants.
DNA rearrangment can be defined as a process which typically involves re-writing the informations contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.
Hence, the ability of an individual to produce over a million different antibody molecules doesn't require the use of over a million different genes; rather, this wide range of antibody production is due to deoxyribonucleic acid (DNA) rearrangment.

Give any 3 parts of a microscope that could make a student see a blurred image.
Answer:
Contrast can be altered by light intensity and staining. How do the coarse and fine focus knobs work on a bright field microscope?
Explanation:
why shouldn't a microscope get wet
Answer:
A hole in the center of the stage allows light to pass from the light source beneath the stage through the slide specimen, which should be centered over the hole in the stage. Keep the stage dry at all times. Fluids can damage metal parts and also make it difficult to move a slide around on the stage.

I just took the test. Its like this because if the Cow does not calf for a few years she is less likely to calf.
a key feature of enzymes is that they _____.
a. interact generally within cells
b. are changed by reactions
c. are carbohydrates
d. are not used up in reactions
e. force reactions to occur
Answer:
d. Are not used up in reactions
Explanation:
This is a property of enzymes. They are not used up since they don't participate in reactions. They just help increase the rate at which it occurs
A key feature of enzymes is that they force reactions to occur. Thus, the correct option for this question is E.
What are Enzymes?Enzymes may be defined as biocatalysts that increase the rate of a chemical reaction without being changed in the overall process. It may be thought that all sorts of cellular reactions or processes are mediated by enzymes.
Most of the enzymes are proteins. They are highly specific in nature. Enzymes also exhibit enormous catalytic power. They do not alter the equilibrium state of biochemical reactions.
Enzymes typically speed up the rate of a chemical reaction by lowering the activation energy of a particular reaction. Thus, it leads to the conversion of reactants into products at a faster rate.
Therefore, a key feature of enzymes is that they force reactions to occur. Thus, the correct option for this question is E.

In a batch culture, bacterial cultures typically exhibit four different phases of growth. In which phase are the cells rapidly synthesizing proteins, but cell numbers are not changing
Answer:
Lag phase
Explanation:
The lag phase is the first phase of bacteria growth and it is refer to period when bacteria is first introduced to the culture and the time it started increasing. The lag phase is the phase bacteria adapt to growth conditions and start surviving in the environment. It is the time bacteria start growing and cannot divide. In this phase , RNA and enzymes are synthesized.

Cual seria el recorrido de una molecula de glicosa desde que es absorbida en el intestino delgado hasta que es metabolizada en el cerebro ?
Answer:
Del intestino delgado ---- torrente sanguíneo --- célula u órgano de almacenamiento.
Explicación:
Después de la absorción de glucosa por el intestino delgado, las moléculas de glucosa se difunden por un gradiente de concentración hacia la sangre capilar dentro de las vellosidades y estas moléculas de glucosa se liberan en el torrente sanguíneo. Cuando las moléculas de glucosa se agregan al torrente sanguíneo, la glucosa puede usarse para la producción de energía o almacenarse en nuestros cuerpos, que puede usarse cuando sea necesario. Si nuestro cuerpo necesita energía esta glucosa es absorbida por las mitocondrias de las células para la producción de energía mientras que por otro lado, si no se requiere energía, estas moléculas de glucosa se almacenan en diferentes órganos en forma de glucógeno.

Question 16
How does the flu vaccine, an injection usually composed of a small amount of live but not harmlul
viral cells, prevent a person from getting sick with the flu virus?
It stimulates the host cell to produce antiviral toxins, which are released
continually into the respiratory tract, to destroy the viral cells even before they
are recognized by white blood cells.
А
B
It prevents the flu virus from converting host cells into pathogenic bacterial cells,
which are the source of a person's symptoms, as it is the bacterial cells that
damage the respiratory tract.
Ос
It initiates the production of memory cells specific for that year's predicted flu
virus. When the flu virus is inhaled, it is recognized quickly by memory cells and
destroyed.
D
It gives a person a mild case of the flu all year long. Since the person already
has an active form of the flu virus, it is impossible to infect that person again
with another flu virus.
Answer:
It stimulates the host cell to produce antiviral toxins, which are released continually into respiratory tract, to destroy the viral cells before they are recognized by the white blood cells.

7. The diagrams show stages in the passage of water through a plant,
The circles are the starting points for arrows to show the direction in which the water moves.
Which circle must have an arrow pointing downwards only?
From the understanding of how water moves through plants, the only circle that can have a downward pointing arrow only is A.
Water moves through a plant in the following direction:
Soil ----> root -----> stem ----> leaves
Once water gets into the root from the soil, a conducting tissue known as xylem conducts the water upward through the stem of the plant branching off into the leaves through the petiole. from the petiole, water is then conducted to the mesophyll cells.
Circle D represents the root, so the arrow must be upward.
Circle C represents the stem, the arrow continues upward towards the leaves
Circle A and B represent the leaf. The movement of water within the leaf might requires that it is from circle A to circle B. Hence, the only circle that must have an arrow pointing downward only can only be A.
