Answer:
used to separate mixtures of DNA, RNA, or proteins according to molecular size
Gel electrophoresis is used for the separation of genetic material present in the cell such as DNA, RNA and even proteins. Thus, the correct option is A.
What is Gel electrophoresis?Gel electrophoresis is a technique which is used to separate the genetic material such as DNA fragments, RNA and proteins on the basis of their size and charge. Gel Electrophoresis involves running an electric current through a gel containing the molecules of interest in it.
The principle of Gel electrophoresis is that the DNA or protein sample to be separated is loaded on to a porous gel placed in an ionic buffer. On the application of electric charge, each of the molecules having different size and charge will move through the gel at different speeds and therefore separates out.
Therefore, the correct option is A.

B. they can metabolize
C. they can't reproduce on their own
D. they can't move on their own
Answer:
they can't reproduce
Explanation:
Viruses rely on the cells of other organisms to survive and reproduce, because they can't capture or store energy themselves. In other words they cannot function outside a host organism, which is why they are often regarded as non living thing
All cells in the body have the same genome, with a couple of exceptions. What are these exceptions?
Answer:
red blood cells, which contain no DNA in their mature state, and some immune system cells that rearrange their DNA while producing antibodies
Cell is the basic unit of life and they contain the needed information known as the DNA (genetic material) to carry out the basic life functions and processes.
All cells in the body essentially have the same genome except some red blood cells and some immune cells.
Red blood cells do not contain as DNA as they lack a nucleus so they are an exception to the rule. While some immune cells needs to reassemble their genome in order to aid in the production of antibodies.
Actually, gene expression comes in with this because cells become different as a result of the fact that a cell can decide which gene is to be expressed or not in accordance to its function it is supposed to perform.

D) social construction.
E) binary arrangement.
Sociologists argue that the division of the human population into two distinctive and mutually exclusive categories, male and female, is best understood as a biological fact.
The division into these two major categories as male or female is mainly due to the biological and the physiological characteristics produced in both male and female.
Although in some cases, it may be argued that they are not mutually exclusive as there are some who have both.
Nevertheless, the above mentioned characteristics are just used to differentiate between a male and a female in humans and as well an individual self-concept of being a male or a female.

All bone formation is a replacement process. During development, tissues are replaced by bone during the ossification process. In intramembranous ossification, bone develops directly from sheets of mesenchymal connective tissue. In endochondral ossification, bone develops by replacing hyaline cartilage, bone formation, also called ossification, process by which new bone is produced. ... Soon after the osteoid is laid down, inorganic salts are deposited in it to form the hardened material recognized as mineralized bone. The cartilage cells die out and are replaced by osteoblasts clustered in ossification centres.

A. is critical for preventing contraction of an antagonist muscle when the other muscle is contracting during voluntary
movement
B. is critical for maintaining the appropriate tension on the spindle organ during contraction of extrafusal fibers.
C. is the process by which Ca2+ is released from the sarcolemma when nicotinic acetylcholine receptors are activated
at the neuromuscular junction
none of the above
The correct option is B.
Alpha gamma coactivation is critical for maintaining the appropriate tension on the spindle organ during contraction of extrafusal fiber.
Alpha‐gamma coactivation is a process that the muscle use to keep or maintains it's length. It works in a way that when the muscle contracts or relaxes , the sensory neuron send the information to the central nervous system about what happen to the muscle. This lead the intrafusal and extrafusal fibers to contract.
Alpha-gamma coactivation enhance the muscle spindles ensure its sensitivity to stretch the muscle lengths.
Therefore, Alpha gamma coactivation is critical for maintaining the appropriate tension on the spindle organ during contraction of extrafusal fiber.

Explain what happens in each stage of mitosis.
no links
Answer:
Stage #1 Prophase: Chromatin fibers become coiled into chromosomes, with each chromosome having two chromatids joined at a centromere.
The mitotic spindle, composed of microtubules and proteins, forms in the cytoplasm.
The two pairs of centrioles (formed from the replication of one pair in Interphase) move away from one another toward opposite ends of the cell due to the lengthening of the microtubules that form between them.
Polar fibers, which are microtubules that make up the spindle fibers, reach from each cell pole to the cell's equator.
Kinetochores, which are specialized regions in the centromeres of chromosomes, attach to a type of microtubule called kinetochore fibers.
The kinetochore fibers "interact" with the spindle polar fibers connecting the kinetochores to the polar fibers.
The chromosomes begin to migrate toward the cell center.
Stage #2 Metaphase: The nuclear membrane disappears completely.
Polar fibers (microtubules that make up the spindle fibers) continue to extend from the poles to the center of the cell.
Chromosomes move randomly until they attach (at their kinetochores) to polar fibers from both sides of their centromeres.
Chromosomes align at the metaphase plate at right angles to the spindle poles.
Chromosomes are held at the metaphase plate by the equal forces of the polar fibers pushing on the centromeres of the chromosomes.
Stage #3: Anaphase: The paired centromeres in each distinct chromosome begin to move apart.
Once the paired sister chromatids separate from one another, each is considered a "full" chromosome. They are referred to as daughter chromosomes.
Through the spindle apparatus, the daughter chromosomes move to the poles at opposite ends of the cell.
The daughter chromosomes migrate centromere first and the kinetochore fibers become shorter as the chromosomes near a pole.
In preparation for telophase, the two cell poles also move further apart during the course of anaphase. At the end of anaphase, each pole contains a complete compilation of chromosomes.
Stage #4 Telophase: The polar fibers continue to lengthen.
Nuclei begin to form at opposite poles.
The nuclear envelopes of these nuclei form from remnant pieces of the parent cell's nuclear envelope and from pieces of the endomembrane system.
Nucleoli also reappear.
Chromatin fibers of chromosomes uncoil.
After these changes, telophase/mitosis is largely complete. The genetic contents of one cell have been divided equally into two.
Stage #5 Cytokinesis: Cytokinesis is the division of the cell's cytoplasm. It begins prior to the end of mitosis in anaphase and completes shortly after telophase/mitosis. At the end of cytokinesis, two genetically identical daughter cells are produced. These are diploid cells, with each cell containing a full complement of chromosomes.
Cells produced through mitosis are different from those produced through meiosis. In meiosis, four daughter cells are produced. These cells are haploid cells, containing one-half the number of chromosomes as the original cell. Sex cells undergo meiosis. When sex cells unite during fertilization, these haploid cells become a diploid cell.

Which is a heterotroph?
A. Grass
B. Lion
C. Dandelion
D. Oak Tree
Answer:
Lion
Explanation:
Heterotrophs are known as consumers because they consume producers or other consumers. Dogs, birds, fish, and humans are all examples of heterotrophs. Heterotrophs occupy the second and third levels in a food chain, a sequence of organisms that provide energy and nutrients for other organisms.
Mountain lions, or cougars, are carnivorous heterotrophs and feed on a wide range of prey, such as insects, small mammals, reptiles and birds, but their most common prey is deer.
Grass, like the majority of green plants, is autotrophic. Thus, Grass produces its food through the photosynthesis process, which uses solar energy, water, and carbon dioxide. Thus, it is not a Heterotroph.
Dandelion is a typical photosynthetic autotroph. (Dandelion) An autotroph is an organism that can produce its own glucose and use it as energy. The Dandelion is a plant that can preform photosyntesis by collecting sunlight, water, and nutrients and create it’s own glucose. This makes the Dandelion an autotroph.
Trees, like all other plants, are autotrophic, meaning that they can produce food through the process of photosynthesis. Oak trees are considered autotrophs because they produce their own food.
