Explain the relationship among
homeostasis, defective mitochondria, and the
symptoms caused by LHON.
Answers
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.

In 1851, Gregor Mendel, a young monk in Europe, formed the foundation of genetics by using pea plants. In one of his experiments, Mendel crossed yellow pea seeds with green pea seeds. Much to Mendel’s surprise, all of the offspring were yellow peas.
Which of the following statements explains Mendel’s results?
A.When the two peas were crossed, the offspring received genes from both parent plants, but the genotype for yellow seed color was dominant over green seed color.
B.When the two peas were crossed, the offspring received genes from both parent plants; the phenotype for yellow peas was dominant over green pea color, which caused all the offspring to have yellow seed color.
C.When the two peas were crossed, the offspring only received the genes from the parent plant which had the genotype for yellow seed color.
B.When the two peas were crossed, the offspring only received genes from the parent plant with the phenotype for yellow seed color, which caused all the offspring to be yellow.
Answers
Answer:
It's A
Explanation: They both have gene for both of the color but the yellow pea seed gene or whatever is dominant.
The statement that best explains Mendel’s results is when the two peas were crossed, the offspring received genes from both parent plants, but the genotype for yellow seed color was dominant over green seed color. The correct option is A.
What is Mendel's law?Gregor Mendel was a scientist and botanist, and he experiments on pea plants and discovered three laws that are very helpful in genetics.
Mendel's law of segregation, "during gamete formation, every gene segregates from each other so that each gamete conveys only one allele for each gene." The second law of inheritance is the law of segregation.
Mendel's 2nd law of inheritance is also known as the law of independent assortment of genes.
It states that each character behaves as a separate unit and is inherited independently of any other character.
Therefore, the correct option is A.

explain why soil micro-organisms should break down plant and animal residues
Answers
Hello there wish you a GREAT Thanksgiving :)
Microbial Soil Organic Matter Decomposition
Organic matter decomposition serves two functions for the microorganisms, providing energy for growth and suppling carbon for the formation of new cells. ... Dead plant residues and plant nutrients become food for the microbes in the soil.
Microbes thrive underneath no-till conditions and winter cover crops. cowl plants and manure may be used to feed soil microbes and recycle soil vitamins. As soil microbes decompose organic residues, they slowly release vitamins lower back into the soil for the winter cowl vegetation or for the preceding crop.
Why soil microorganisms should break down plant and animal residues?
By-products from growing roots and plant residues feed soil organisms. In turn, soil organisms support plant health as they decompose organic matter, cycle nutrients, enhance soil structure and control the populations of soil organisms, both beneficial and harmful (pests and pathogens) in terms of crop productivity.
What's the significance of microorganisms within the soil what's their role?Useful soil microbes carry out fundamental capabilities which include nutrient cycling, breaking down crop residues, and stimulating plant boom. at the same time as the position of microbes to preserve soil fitness and make contributions to crop performance is clear, the soil organic factor is extremely difficult to take a look at and control.

Meiosis is a process of Cell division in which the number of chromosomes per cell is cut in __________ and homologous chromosomes in a ___________ cell are separated. Meiosis involves two distinct stages: meiosis I and ___________. One diploid (full # of chromosomes) cell becomes ____haploid (half # of chromosomes) daughter cells.
Answers
Answer:
Explanation: This process is called mitosis. However, parental gametes – the sperm and egg cells – are unique from all other cells in that they reproduce through a process called meiosis. The purpose of meiosis is to shuffle genetic information and cut the cellular chromosome number in half, from 46 chromosomes to 23 chromosomes. In this way, when an egg and sperm cell combine during fertilization, the resulting embryo will inherit the appropriate amount of unique genetic information from each parent.tion:

The amount of fossil fuels formed is approximately the same as the amount used. The amount of fossil fuels formed is much less than the amount used. The amount of fossil fuels formed is greater than the amount used.
Answers
Answer:
The amount of fossil fuels formed is much less than the amount used.
Explanation:
Fossil fuels, which include petroleum, coal, natural gas etc are an example of non-renewable sources of energy. They are termed non-renewable because they are sources that gets exhausted quickly without replenishment.
One of the characteristics of non-renewable sources of energy is that they get exhausted faster than they can be produced. Hence, regarding fossil fuels as an example of non-renewable source of energy, this means that the amount of fossil fuels formed is much less than the amount used.

O D and A
Answers
Answer:
According to the plant cell scheme, the two structures that produce energy that cells can use are D, which corresponds to mitochondria, and A, which is a chloroplast, so the answer is D and A (fourth option).
Explanation:
In the plant cell —unlike the animal cell— there are organelles called chloroplasts, responsible for converting light energy from the sun into chemical energy. In addition, there are mitochondria, which also provide useful energy to the cell.
In the chloroplast, photosynthesis takes place, a process that during the light phase produces ATP and NADPH⁺ from solar energy. In the mitochondria, energy in the form of ATP is obtained from glucose, due to oxidative phosphorylation and the electron transport chain.The organelles indicated in the diagram are mitochondria (A) and chloroplast (D), both responsible for producing energy for the plant cell.

Answers
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.

The chromosomes in the daughter cells are half the number from the parent cell. So, the correct option is (A).
What is Mitosis?Mitosis is defined as the part of the cell cycle in which the duplicated chromosomes are divided into two new nuclei. Cell division by mitosis gives rise to genetically identical cells in which the total number of chromosomes remains the same. Hence, it is also known as Equilateral Partition.
The phases involved in the mitosis are :-
ProphasePrometaphaseMetaphaseAnaphaseTelophase.Mitosis occurs in somatic cells which occurs in all types of cells that are not involved in the production of gametes. Each mitotic division contains one copy of each chromosome, thus a complete set of chromosomes is found in the nucleus of each new cell.
