What are cell biology, genetics, and
molecular biology?
Answer:
Explanation:
Cell biology (also cellular biology or cytology) is a branch of biology studying the structure and function of the cell, also known as the basic unit of life. Cell biology encompasses both prokaryotic and eukaryotic cells and can be divided into many sub-topics which may include the study of cell metabolism, cell communication, cell cycle, biochemistry, and cell composition.
Genetics, study of heredity in general and of genes in particular. Genetics forms one of the central pillars of biology and overlaps with many other areas, such as agriculture, medicine, and biotechnology. Learn more about the history, biology, areas of study, and methods of genetics.
Molecular biology, field of science concerned with studying the chemical structures and processes of biological phenomena involving molecules. In particular, researchers focus on DNA, RNA, and proteins and their interactions. As a result, the field is closely related to genetics and biochemistry
The study of heredity is a field of genetics and cell biology. The DNA itself (molecular genetics), entire populations, or whole creatures are investigated at various levels of genetics (population and evolutionary genetics).
What relation between cell biology and molecular biology?Two branches of biology are cell biology and molecular biology. The study of cellular mechanisms is a focus of the subject of cell biology.
As a result, it primarily concerns the functions and architecture of the cell. The study of molecular level mechanisms is a focus of the science of molecular biology.
Therefore, cell biology, genetics, and molecular biology are interconnected.

Explain the relationship among
homeostasis, defective mitochondria, and the
symptoms caused by LHON.
Answer:
There is an important relationship among homeostasis, defective mitochondria, and the symptoms caused by LHON.
Explanation:
There is a great relationship among homeostasis, defective mitochondria and the symptoms caused by LHON because defective mitochondria disturbs the homeostasis in the body. If mitochondria works properly, homeostasis will be maintained whereas if there is any defect occurs in the mitochondria then the whole homeostasis will be adversely affected because mitochondria is the powerhouse of the cell responsible for the production of energy for the cell. Symptoms occurs due to Leber's hereditary optic neuropathy (LHON) also effected the state of equilibrium in the body.
The relationship among homeostasis, defective mitochondria and the symptoms caused by LHON is the following:
The power center of the cell, the mitochondria are also involved in homeostasis, the maintenance of a stable internal environment even in the face of variations in the external environment.
Mitochondrial diseases can be caused by inherited mutations in mitochondrial DNA or defects in the proteins responsible for regulating mitochondrial division, affecting the body's homeostasis.
Leber's Hereditary Optic Neuropathy (LHON) is the first disease associated with a mutation in the mitochondrial genome, specifically it produces the specific degradation of neurons involved in sending information from the eye to the brain (RGC).This disease is caused almost entirely by three mutations in mitochondrial DNA (mtDNA).The first symptoms are blurred vision, with unilateral or bilateral onset, which over time affects and / or worsens in both eyes, with loss of visual acuity and color vision.Vision loss is painless and is caused by degeneration of the optic nerve, specifically of the retinal ganglion cells (RGC).
Therefore, we can conclude that LHON is a disease associated with a mutation in the mitochondrial genome affecting the body's homeostasis.

Answer: I think it is d
Among the given options, immigration is considered as the limiting factor to a population. Thus, the correct option is D.
What is Population?A Population may be defined as the number of individuals of the same species living in a particular area at a definite time. It also represents the number of males and females in any population with respect to their characteristics.
Competition, predation, and human disturbances are responsible for the reduction of any population. This is because these factors generally involve the ultimate death of individual and health damage.
While immigration is typically a process through which an individual has come in order to live in that place. This place is not native to the individual. This increases the population of any specific region.
Therefore, among the given options, immigration is considered as the limiting factor to a population. Thus, the correct option is D.

Plants such as the Venus Flytrap and the Sun Dew attract and consume insects. These plants are unable to produce substances which break down the insect into compounds that are usable by the plant. The chemical compound that breaks down the insects is most likely * O ATP O Lipids O Enzymes O Vitamins
Answer:
The chemical compound that breaks down the insects is most likely enzymes.
Explanation:
Venus flytraps and sundews are carnivorous- they consume insects to absorb nutrients via digestion. During absorption, their cells take up molecules synthesized via the breakdown of macromolecules like carbohydrates and proteins. When regions of the plant come into contact with insects, these plants recognize specific macromolecules like chitin, they increase the production of digestive enzymes.
Forming digestive liquid enzymes are specialized proteins that function as biological catalysts to speed up reactions. They act on substrates, which can bind to specific regions of the enzyme, called the active site. Once bound in the presence of highly specific temperature and pH, enzymes increase the rate of a reaction over time.
Common enzymes found in their digestive secretions include chitinases, phosphatases, amylases, and proteinases.

Gregor Mendel conducted thousands of genetic experiments using pea plants. Mendel is called the Father of Genetics because it was these studies that lead to the principles of genetics. In one of his many experiments, he crossed purple-flowered pea plants with white-flowered pea plants. Much to his surprise, all of the offspring turned out to be peas with purple flowers in appearance.
Although Mendel used the term factors instead of genes, how did Mendel explain why all the pea plants had purple flowers and not a mixture of white and purple flowers?
A.The offspring received the factors (genes) from both parents, but the genotype for purple flowers dominated over white flower pea plants.
B.The offspring only received the factors (genes) from the parent with the genotype for purple flowers and nothing from the white flower parent.
C.The offspring received the factors (genes) from both parents, but the phenotype for purple flowers dominated over the factor for white flowers.
D. The offspring only received the factors (genes) from the parent with the phenotype for purple flowers and nothing from the white flower parent.
Answer:
A
Explanation:
The purple gene was dominant, so though the plants got "factors" from both parents, only the purple gene was expressed in their phenotype (purple petals).

A defensive soccer player is having trouble reacting quickly to the movements of the opposing player. How can the soccer player adjust her base of support to improve her reaction time?
Answer:
decrease the base of support and centralize her line of gravity
Explanation:
A wider base of support leads to an unsteady gait. The base of support is the contact between the feet of the soccer player and the surface (the field) supporting him. The root cause of the player's inability to react quickly to the movements of the opposing player is a lack of balance.
Balance is the ability of an individual to sustain the line of gravity which runs the center of gravity. For the player to regain his balance, she needs to decrease the base of support and centralize her line of gravity, so as to maintain balance.

Analyze the document "King Andrew the First (c. 1833)” by explaining its "HIPP” (historical context, intended audience, author’s purpose, and author’s point of view). Refer to elements in the image to explain your response.
Answer: Andrew Jackson was a strong president. He used the office to forcefully pursue his agenda. This cartoon is quite famous, coming out around 1833, because of the 1833 removal order. In the cartoon, the president can be seen holding a veto in his hand, and standing on top of the Constitution. He is dressed up as a king, holding - perhaps - too much power. I believe that the intended audience was the people. The people saw him as a king, abusing his powers as a president. The author’s purpose was to show how people truly viewed him. The president’s order to remove federal deposits from the Bank of the United States led to an increase in state debt. The President was strongly criticized because he acted without congressional approval, as a king would.

When an antigen attacks the body, it activates adaptive immunity. This adaptive immunity produces a strong response when it encounters the same antigen for the second time. Which feature of adaptive immunity is essential for this kind of response?
Answer:
A) the ability to remember the antigen it encounters
Adaptative immunity reacts in a more general way producing nonspecific antibodies against the foreign antigen when the organism is first attacked by that foreign antigen. The second time around, when the organism is faced again with the same foreign antigen, it produces a much stronger response because it memorised the antigen and is not strange anymore so the response can be more specific, quicker, and effective.
