Answer:
Daughters who are descendants of a woman carrier of Fragile X Syndrome and a healthy man will have a 50% chance of having or being carriers of the syndrome.
Explanation:
Fragile X syndrome has an autosomal dominant inheritance pattern, linked to the X chromosome. That is, someone with an altered X chromosome can either be a carrier or have the syndrome.
In this case, the mother is a carrier of the altered chromosome (X) while the father is neither a carrier nor has the condition (XY).
Cross X x XY
Alleles X Y
[tex]X^{f}[/tex] [tex]X^{f}[/tex]X [tex]X^{f}[/tex]Y
X XX XY
The couple has a 50% chance of having daughters, and of those daughters half (50%) have the chance of having an Xf chromosome, and being a carrier or suffering from the syndrome.

Explain how 1st and 2nd law of thermodynamics applies to the trophic structure of an ecosystem?
Answer:
First law: In the ecosystem, the energy flow from lower levels of the food chain to the highest levels
Second law: During energy transference between trophic levels, the main part of the energy is lost as heat and other processes.
Explanation:
The first law of thermodynamics states that the energy can not be created or destroyed, but instead it is transformed into one type to another. Moreover, the second law states that when energy is transformed an important proportion of this energy is lost as heat, and it increases the entropy level.
In an ecosystem, the energy flow is unidirectional, it means that energy flow from primary producers to primary consumers, then from primary consumers to secondary consumers and so successively in all levels. Moreover, organisms fight against entropy by converting foods into energy (which is used to maintain order within their cells. During the feeding process, the energy intake is not 100 % efficient, it means that most part of the energy is lost as heat (approximately 90%), thereby increasing the entropy in the ecosystem.
if one species in a community dies out or moves, the community will
Answer:
The community will slowly decline, or be just fine, or be better off.
Explanation:
Wolves being killed in Yellowstone showed that Yellowstone suffered, because there was nothing to kill the elk, so their population exploded and they ate everything.
If certain rats were gone in certain areas, then the community/environment would be fine, because rats eat birds and other small animals (they eat too many of them).
And if stray cats were gone then certain forests would be better off and see an increase in birds population, stray cats eat birds.

Conduct online research to learn more about competition between two species not mentioned in this lesson. Make sure to include information about their niches, common resources, and other competitors.
Answer:
In many forest ecosystems, squirrels and chipmunks compete for acorns and some other resources. However, they don’t have the exact same niches. Squirrels nest in trees, while chipmunks live underground. These species don’t compete with each other for mates either. Thus, squirrels are in interspecific competition with chipmunks.
All squirrels in a particular ecosystem share the same niche. The same is true of all chipmunks. So, both of these species are in intraspecific competition. Competing with an individual from the same species is harder than competing with members of other species. For example, squirrels compete with other squirrels for not only food (acorns), but also shelter and mates. However, they also compete with some other species, such as deer and acorn weevils, for acorns. Furthermore, they are both prey for many of the same predators, such as hawks, raccoons, foxes, and weasels.

what are the different parts of microscope ?A microscope is which produces large images of tiny substance and provide observer a close view of minute structures at a convenient scale for examination and analysis.
Anatomically the microscope consist of three structural parts, i.e. head, base, and arm, where head is known as the body and it carries the optical parts in the upper part of the microscope.
Base of microscope is used to support and carries microscopic illuminators and Arms connect the base and the head and the eyepiece tube to the microscope base.
The optical parts are basically applied for the view, magnify, and production of an image from a specimen placed and the various parts.
Eyepiece or ocular located at the top of the microscope with standard magnification is 10X, Eyepiece Tube which carries the eyepiece just above the objective lens.

What will happen to the pressure in the brain if water moves into it from the blood?
Answer:
A sudden increase in the pressure inside a person's skull is a medical emergency. Left untreated, an increase in the intracranial pressure (ICP) may lead to brain injury, seizure, coma, stroke, or death. With prompt treatment, it is possible for people with increased ICP to make a full recovery
Explanation:
A medical emergency occurs when a person's internal pressure suddenly increases. An increase in intracranial pressure (ICP) may cause brain damage, seizures, comas, strokes, or even death if left untreated.
What is brain?The brain is a sophisticated organ that manages every bodily function as well as thought, memory, emotion, touch, motor skills, vision, respiration, temperature, and hunger. The central nervous system, or CNS, is made up of the spinal cord that emerges from the brain.
There are two distinct parts of the central nervous system: gray matter and white matter. Gray matter in the brain refers to the thicker, outer layer, and white matter to the thinner, inner layer beneath.
It is possible for patients with elevated ICP to fully recover with prompt treatment.

A nerve impulse is an electrical charge running across a neuron. Explain why the simulation supports this explanation.
Answer:
Sudden reversal of the electrical charge across the membrane of resting neuron
Answer:
Stimulation of a neuron causes a change in the charge inside the cell from negative to positive. This change is caused by ions, which are atoms with an electrical charge, moving across the cell. This change within the cell is consistent with the definition of an electric charge.

What is the use of reverse transcriptase?Reverse transcriptase enzyme has been generally used by the retrovirus for their genome replication. This enzyme has been discovered by the Howard tenim.
Reverse transcriptase enzyme generates the complementary DNA from the mRNA template by the process of reverse transcription. The presence of RNase H, RNA-dependent DNA polymerase and DNA-dependent DNA polymerase activity enable the enzyme to convert the mRNA into DNA.
The position of the mRNA is to carry protein facts from the DNA in a cell's nucleus to the cellular's cytoplasm (watery interior), where the protein-making machinery reads the mRNA sequence and translates every three-base codon into its corresponding amino acid in a growing protein chain.
Therefore, The mRNA sequence will best match the section of DNA shown below is C-U-A-G-G-A. Thus, option C is correct.

When the concentration of molecules on both sides of a membrane is the SAME, the solution is
Answer:
When the concentration of molecules of a substance is the same on both sides of a membrane the solution is isotonic.
Explanation:
A given substance, when it has the same concentration on both sides of the membrane, is in equilibrium and the solution is called isotonic, from the extracellular space with respect to the cytoplasm.
The cell membrane is semipermeable to the passage of water and some substances. Hypertonic and hypotonic solutions tend to establish the dynamics of entry and exit of molecules or water, due to the concentration or osmotic gradients that are established, respectively.
An isotonic solution does not generate gradients, because the concentration of molecules is equal in the extracellular space with respect to the intracellular space.

Why is it important to have a control group in the experimental design?
The control group is the main one because it acts as a benchmark to balance the results of the experiment.
What is control group in the experiment?Control groups are a principal aspect of true experimental designs. The presence of control groups authorizes researchers to confirm that study results are due to the drafts of independent variables rather than irrelevant variables. The control group of an experiment is a group that is not revealed to the independent variable and thus serves as a benchmark to which to compare the outcome of the experimental group. An experimental group, also known as a use of group, receives the treatment whose effect researchers wish to study, whereas a control group does not. They should be similar in all other ways.
So we can conclude that an example of a control group is a group of individuals in a detached trial that receive placebo pills instead of medication.
