24) is it possible to know the genotypes of the three children in generation 111?
should their shapes be shaded? explain your answer to both questions.
Answers
Answer:
The genotype of all children in generation III is Hh. as H comes from dad and h comes from the mother for every case.
yes, their figures should be shaded.
reason :-
The dominant allele Fort this disease is shown by H whereas the recessive trait shown by h.
each offspring in generation III has the genotype Hh
and the presence of one dominant allele is enough to cause the disease.
all children in generation 3 suffer from the disease and so their figures should be shaded

The student wants to see the cells at a greater magnification. Describe the steps that she should take.
Answers
Gradually turn the crude focus knob until you can see the cells. Turn the fine focus knob slowly until the cells are in focus and visible.
What is magnification?Magnification is the process of enlarging something's apparent size rather than its physical size.
This enlargement is measured by a calculated number known as "magnification." When this number is less than one, it refers to a size reduction, also known as minification or de-magnification.
The magnification of a compound microscope is the product of both lenses, so if the microscope has a 10x eyepiece and a 40x objective, the total magnification is 400x. Magnification is defined as the ratio of the image size to the object size.
The student should use the adjustment knobs to bring the sample back into focus after selecting the x40 or x10 objective lens.
Thus, these steps are necessary to see cell's magnification.

A population of tree frogs lives in an area that has many types of plants and trees. The skin of most of the frogs is gray, which blends in better with the bark of trees than with the leaves of plants. Some of the frogs have skin that is greener in color, which blends in better with grasses and leaves. Snakes and birds are predators of the frog. Humans have come to the area and are beginning to cut down the trees. Describe the probability of survival for the three frogs of each genetic variation of skin colour if most of the trees are cut down. Use evidence in the paragraph to support your answer.
Answers
Answer:
with the normal natural predators their chances of survival are high but when humans step in entire forests can be wiped out which will endanger every species of frog
If most trees are cut down, grey individuals will not survive because they will be more exposed to predation. Green frogs will show a greater survival rate. Directional selection is favoring the green phenotype and its genotype.
What is directional selection?
Directional selection is one of the different types of natural selection.
It increases the proportion of individuals with an extreme phenotypic trait.
It causes a decrease in the number of individuals expressing intermediate phenotype, and the other extreme phenotype.
This selection presents more frequently in those cases in which interactions between living organisms and the environment modify in the same direction.
In the exposed example, there is a natural environmental pressure: predation. Frogs need to camouflage to avoid being seen by birds and snakes.
Most frogs are grey. They camouflage with the bark of treesSome other frogs are green. They camouflage with the grass and leaves.The curve in a graph frequency vs phenotype shows a higher frequency of gray individuals.
When humans cut down the trees, they are applying another pressure to the population.
Since humans remove trees, grey frogs remain without a substrate in which to camouflage. They are now exposed to predation.
Birds and snakes can detect the gray frogs better and prey on them.
The grey phenotype and its genotype are affecting the animals' fitness. Grey frogs do not get to survive. So natural selection does not favor it.
Natural selection tends to benefit the green phenotype, which is now the one that increases the frogs' fitness. Green animals are not seen by predators, so they get to survive.
The curve in a graph frequency vs phenotype now shows a higher frequency of green individuals and a sharp decrease of grey frogs.
If more trees are cut down, grey individuals will not survive. However, green frogs will show a greater survival rate.
Directional selection is favoring the green phenotype and its genotype.

The reason that the mail bed appears pink is the presence of a larger number of melanocytes in the underlying dermis
Answers
Complete question:
True or False: The reason that the nail bed appears pink is the presence of a larger number of melanocytes in the underlying dermis.
Answer:
False
Explanation:
Nails are composed of the lamina, which is a smooth, shiny, translucent, and keratinized structure. The nails are born the nail matrix. The newly formed nail slice along the mail bed, which is the plane surface under the nails.
The nail bed places under the nail and is composed of a thin epithelium, with no granulous stratum, and a few layers of parakeratotic cells attached to the nail.
The nail matrix and nail bed have melanocytes. Half of the melanocytes of the matrix produce melanin, while melanocytes of the nail bed are inactive.
The nail bed is laying over many small vessels that nourish it and provides a pink color to the nails.
When the stimulus voltage is increased, _______. When the stimulus voltage is increased, _______. sodium permeability into the cell decreases sodium permeability into the cell increases to overcome the potassium exiting a greater-than-threshold depolarization results a greater-than-threshold depolarization results and sodium permeability into the cell increases to overcome the potassium exiting.
Answers
Answer:
a greater-than-threshold depolarization results and sodium permeability into the cell increases to overcome the potassium exiting.
Explanation:
The occurrence of action potential requires the existence of active voltage-dependent channels to open and close in response to the membrane depolarization.
When depolarization reaches and supers the threshold point, voltage-dependent Na+ channels open and the ion gets into the cell. The entrance of Na+ decreases the electric charge difference between the cellular interior and exterior. Membrane depolarizes and produces the action potential that tends to reach a potential equilibrium for Na+ = +60mV. The higher the Na+ input is, the greater is the depolarization and the greater is the Na+ permeability.
Once Na+ channels are closed, voltage-dependent K+ channels open, increasing the membrane permeability to the ion, letting K+ get out of the cell, following the electrochemical gradient.
The closure of Na+ channels and opening of K+ channels are responsible for membrane repolarization.
Take a look at the two boxes below. Each box has the same volume. If each ball has the same mass, which box 1 or 2 would weigh more? Why?
Answers
Answer:
Box 1.
Explanation:
The box 1 have the more mass because there are large number of balls present in the box while on the other hand, box 2 has less number of balls in the box. The volume of box boxes are the same as well as weight of the both boxes before placing of balls. Placing of balls changes the weight of both boxes because of the presence of different number of balls in each boxes.

Rapid growth of cells is observed in tumors. One hypothesis of rapid tumor growth is that the creation of new cells uses old cells only as a scaffold to promote rapid growth similar to how crystal solids form. In this hypothesis, new cellular material is not created from preexisting cells. First a new nucleus of a cell attaches to the preexisting cells followed by the formation of the cytoplasm and lastly a cellular membrane forms around the cytoplasm-nucleus complex. This process can only happen if there is a pre-existing lattice network of cells that can function as a site of nucleation. Group of answer choices This hypothesis is not supported by cell theory because new cells are not created from older, preexisting cells. This hypothesis is not supported by cell theory because cell walls are required to grow new cells
Answers
Answer:
This hypothesis is not supported by cell theory because new cells are not created from older, preexisting cells.
Explanation:
This hypothesis does not agree with cell theory because it states that new cells do not need pre-existing cells to be created. Cell theory states that cells are generated from old, pre-existing cells, which go through the process of cell division to create new cells.
We can see the disagreement of this hypothesis with the cell theory in the lines:
