What are chromosomes?
Answer:Chromosomes are thread-like structures found within the nucleus of both animal and plant cells. Protein and a single molecule of deoxyribonucleic acid make up each chromosome (DNA). DNA is passed along from parents to children and carries the precise instructions that distinguish each living thing.
The word "chromosome" is derived from the Greek terms "chroma" and "body" (soma).
--------------------------hope it helps...have a great day!!During which phase of the cell cycle are chromo-
somes copied?
Answer:
S phase
Explanation:
S phase is the second phase of interphase (longest phase where cell grows and replicates it's DNA and does it function. It is broken up into smaller sub phases). S phase is the synthesis phase. During this phase chromosomes are replicated ( The DNA is copied).
The microscopes we use today are far more complex than those first microscopes like the one used in the 1600s by Anton van
Leeuwenhoek. Despite the limitations of his simple microscope, van Leeuwenhoek observed some cells he termed
"animalcules." Robert Hooke then coined the term "cell" for the box-like structures he observed when viewing cork tissue
through a lens. Later advances in lenses, microscope construction, and staining techniques enabled other scientists to see
some components inside cells. Just as the microscope has been a work in progress with advances that have led to our current
technology, so the cell theory changed as new discoveries changed the understanding of cells.
Which of these contributed to the cell theory? Select ALL that apply.
A)
Robert Brown discovered the nucleus of plant cells.
B)
Matthias Schleiden discovered that plants are made of cells.
o)
Rudolf Virchow proved that cells come from preexisting cells.
D)
Theodor Schwann discovered that animals are composed of cells.
E)
Karl Rudolphi conducted experiments that proved cells had their own cell
walls.

What is microscope?
The instrument that is used to observe tiny particles as well as objects or cell of the body has been known as microscope. One lens in the microscope has been used to magnify the image at least once. The main function of the lens has to bend the light in the direction of the eye and forms the larger image of the object.
There are several types of microscope and these are electron microscope,scanning probe microscope, stereomicroscope, simple microscope, and light microscope.The main function of the lens has to bend the light in the direction of eye and forms the larger image of the object.
Each microscope have different function and ability to observe the object. As we know that the size of the cell has very small and it has impossible to observe it without microscope. So, microscope helps to observe the interior part of the cell and it will help in the study of different part of cell.
Therefore, The microscopes we use today are far more complex than those first microscopes like the one used in the 1600s by Anton van Leeuwenhoek.

Explanation:
Quade is studying for an exam, which will cover neurons and action potentials. He has drawn a diagram that shows the segments of an axon, and he has noted that every time a segment fires, the _____ flood in from the outside of the cell, while the prior segment returns to its resting potential. Please choose the correct answer from the following choices, and then select the submit answer button.
Answer: positive sodium ions
Explanation:
This relates to the Action Potential which is what a nerve cell goes through when it needs to send information down the nerve cell to another cell and so on till it gets to the destination of the message.
The information is transmitted when the segments of the axon fire and when they do, positive sodium ions come in from outside the cell to the inside thereby making the inside positive. The previous segment would return to a resting potential when potassium ions which are negative, rush into the cell.

B. the alleles each parent can contribute in their gametes.
Answer:
B. the alleles each parent can contribute in their gametes.
Explanation:
This observation forms the second principle of inheritance, the principle of segregation, which states that the two alleles for each gene are physically segregated when they are packaged into gametes, and each parent randomly contributes one allele for each gene to its offspring.

Identifying an individual's genetically influenced health risks could increase their potential to achieve optimal health.
Answer:
Yes.
Explanation:
Yes, Identifying an individual's genetically influenced health risks could increase their potential to achieve optimal health because necessary steps can be taken in order to prevent the disease from more spreading and cause damaged to the body. Identification of genetical disease can be prevented to cause damage if the factors that triggers the disease can be avoided so we can conclude that identification of genetically influenced health risks can increase the chances of getting good health.

The idea of laissez-faire, or how much the government should do, is
DONE
Answer:
Laissez-faire means that the government does not interfere with people's right to pursue happiness.
The idea of laissez-faire, or how much the government should do, is debated heavily.
Explanation:
Laissez-faire is the main concept defended by economic liberalism and capitalism, mainly in the USA and other countries that adopt this type of concept. In a simple way, Laissez-faire can be defined as the separation of the State and the commerce of a region. This means, that in places where Laissez-faire is adopted, the State, ie the government, does not have the right to interfere in any type of commercial relationship and should only be responsible for guaranteeing property rights and consumer protection, otherwise, trade must regulate itself, within its own limits.
While many people see this policy as beneficial, preventing government from interfering with people's happiness, others believe that Laissez-faire is not beneficial and that government interference, or lack of it, should be discussed.

What is boiling factor ?
The boiling factor of a liquid varies in keeping with the carried out strain; the everyday boiling factor is the temperature at which the vapour strain is identical to the same old sea-degree atmospheric strain (760 mm [29.92 inches] of mercury). At sea degree, water boils at 100° C (212° F).
Thus it is well explained.

Explain how Sodium and Potassium exchange during active transport Write your answer in steps.
Answer:
Three sodium ions are extruded from and two potassium ions are imported into the cell.
Explanation:
Sodium-Potassium pump occurs during active transport in which sodium ions are removed and sent outside the cell while on the other hand, potassium ions are moved inside the cell due to their needs in the cell. Three sodium ions are moves outside the cell whereas two potassium ions are imported into the cell with the use of ATP molecules. The exchange occurs till the equilibrium of inside and outside environment can be achieved.
One reason why anabolic steroids can imitate the hormone testosterone is because
(1) anabolic steroids and testosterone both interact with the same cell receptors
(2) testosterone acts only on muscle cells
(3) females produce small amounts of the hormone testosterone
(4) an increase in testosterone in males using anabolic steroids increases male features
Answer:it’s 4 (an increase in testosterone in males unsung anabolic steroids increases male features
Explanation:
Anabolic steroids can imitate the hormone testosterone is because they both interact with the same cell receptors.
What do you mean by anabolic steroids?"Anabolic steroids are synthetic (man-made) versions of testosterone."It is used to enhance physical appearance by increasing muscle mass and decreasing fat.What is testosterone?"Testosterone is the male s ex hormone that is made in the testicles."It helps in regulating male s exual development and functions.What are cell receptors?"Structures found in the plasma membrane (surface) of cells that tightly bind specific molecules."It functions in information transmission.The anabolic steroids interact with same cells receptors as that of testosterone and results in increase of testosterone level causing increase in muscle mass.
Hence, the correct option is 1. anabolic steroids and testosterone both interact with the same cell receptors.
