This is an example of an Obligate anaerobe

Obligate anaerobes are organisms that require an oxygen-free environment in order to survive and grow. Staphylococcus epidermidis is able to use fermentation to survive in pores without oxygen, meaning that it is an organism that does not require oxygen to survive.

Instead, they rely on fermentation or other anaerobic metabolic processes to generate energy. Examples of obligate anaerobes include Clostridium species, Fusobacterium species, Bacteroides species, and Staphylococcus epidermidis.

These organisms can be found in a variety of environments, such as deep sea hydrothermal vents, soil, and the human body. Obligate anaerobes are important for a variety of processes, such as breaking down organic matter and generating energy for other organisms.

RNA contains the nitrogenous base uracil. Its complimentary base is adenine. Adenine invariably interacts with uracil in RNA (A-U).

The polymeric molecule ribonucleic acid (RNA) plays numerous biological roles in the coding, decoding, regulation, and expression of genes. The two types of nucleic acids are RNA and DNA. The four main macromolecules required for all known forms of life are lipids, proteins, carbohydrates, and nucleic acids. The building blocks of RNA are nucleotides, just like DNA, however unlike DNA, RNA exists in nature as a single strand folded over itself rather than a paired double strand. In cellular organisms, messenger RNA (mRNA) carries genetic instructions that instruct the synthesis of particular proteins. A large number of viruses use RNA genomes to encode their genetic material.

In Drosophila, sex is determined by a balance between the number of haploid sets of autosomes and the number of X chromosomes.

Drosophila, also known as fruit flies, are small, winged insects that have been widely used as a model organism for over a century because of their small size, rapid life cycle, and simple care requirements, as well as the wide range of genetic and molecular tools available to manipulate and study them. They have provided important insights into the mechanisms of genetic inheritance, developmental biology, and evolution.

The presence of one or two X chromosomes determines whether an individual develops as a male or female, respectively. The presence of one X chromosome leads to the development of a male, while the presence of two X chromosomes leads to the development of a female. This is known as X-chromosome dosage compensation.

It is crucial to remember that DNA replication happens simultaneously in both strands of the molecule. Each new DNA molecule is created by a semi-conservative replication process and has both its original and new strands.

DNA replication happens in these steps:

An enzyme known as helicase unwinds and separates the double-stranded DNA molecule to start DNA replication. Then, using the RNA primer as a starting point, the enzyme DNA polymerase adds nucleotides to the template strand of DNA. As DNA replication polymerase continues to add nucleotides to the new strand, strengthening it as it goes, DNA replication proceeds. In the last stage, called ligation, the enzyme ligase binds the new strand's sugar-phosphate backbone, creating an entirely new DNA replication molecule.

Answer:

Explanation:

The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.

During photosynthesis, in order to achieve a compensation point or to limit gas exchange reaction, we would need to stop the chemical reaction of pyruvate becoming acetyl CoA since this reaction produces gas. Also, we would have to restrict the cell from receiving water since the Krebs Cycle produces CO2 by using water.

In general, photosynthesis is an important chemical reaction and also responsible for the existence of life on earth.

During this process , light energy is used by the plant to convert CO2 and water into carbohydrates through cellular respiration. The chemical equation for photosynthesis is 6CO2 + 6H2O → C6H12O6 + 6O2. In this reaction six molecules of carbon dioxide and six molecules of water are consumed to from six molecules of glucose. Oxygen is formed as by product and is main source of survival for human beings.

Mutations are the factor most likely to increase genetic diversity in a population. When an organism mutates, new genetic information is created.

The nucleic acid sequence of an organism's, virus's, or extrachromosomal DNA can change due to a mutation. RNA or DNA make up viral genomes. Errors in DNA replication, viral replication, mitosis, meiosis, or other types of DNA damage (such as pyrimidine dimers from exposure to ultraviolet radiation) can result in mutations. These errors can also occur during repair processes, such as microhomology-mediated end joining, which is prone to error (translesion synthesis). Mobile genetic elements can cause mutations by causing the insertion or deletion of DNA sequences.

Sequence changes can take many distinct forms as a result of mutation. Gene mutations can have no effect, change the gene's product, or stop the gene from working fully or correctly. Non-genic areas are likewise susceptible to mutation. Large portions of DNA can be duplicated during mutations, usually as a result of genetic recombination. Tens to hundreds of genes are replicated in animal genomes every million years, which serves as a significant supply of genetic material for the development of new genes.

For efficient nutrient uptake and waste disposal, cells must be somewhat small in size.

The cell's small size allows for metabolic movement similar to the movement of items from smaller utensils, and the nucleus can also govern cytoplasmic processes effectively. Cells are so small that they can maximize their area to volume ratio. Smaller cells have a better ratio, allowing more molecules and ions to penetrate the cell membrane per unit of cytoplasmic volume. As a result, if the cell grows beyond a certain point, not enough material will be available to cross the membrane quickly enough to meet the increasing cellular volume.

Limiting factors are any factors that limit the growth, reproduction, or survival of organisms within an ecosystem. In the tropic levels of an ecosystem, limiting factors can affect the flow of energy in several ways:

By limiting the productivity of primary producers: Primary producers such as plants and algae are the base of the food chain and are responsible for converting energy from the sun into organic matter. If limiting factors such as temperature, water, or nutrients are limiting their growth, then the amount of energy available for the next tropic level will also be limited.

By limiting the population of consumers: Consumers such as herbivores and carnivores rely on the energy from primary producers to survive. If limiting factors such as predators, disease, or competition for food limit their population, then the amount of energy available for the next tropic level will also be limited.

By limiting the efficiency of energy transfer: Limiting factors such as predation, competition, and disease can affect the efficiency of energy transfer between tropic levels. For example, if predators are scarce, then herbivores may have a higher survival rate, and thus a higher proportion of the energy they consume will be available to transfer to the next tropic level.

In summary, limiting factors can affect the flow of energy in the tropic levels of an ecosystem by limiting the productivity of primary producers, limiting the population of consumers, and limiting the efficiency of energy transfer between tropic levels. As a result, the amount of energy available for the next tropic level will also be limited.

We conclude that there is a relationship between gender and dreams for the comparision of given data.

As per the given matrix: Gender Female 18 4 2 and Male 4 17 15.

Initially state the hypotheses and select an alpha level as:

H0: In the population, dream is independent of (NOT related to) gender

Ha: In the population, dream is related to gender

Given α = 0.01

Then compute the degrees of freedom (df)

df = (#Columns - 1) * (#Rows - 1) = (3-2) * (2-1) = 2

find the critical value in the chi square statistic table

For this example, with df = 2, and α = 0.01 the critical chi-squared value is 5.99. Then collect the data and compute test statistic as below:

Obtain row and column totals, also called the marginals as the total members in low = 18+4 =22 in medium = 4+17 = 21 in high = 2+15 = 17

Total number of dreams (n) = 22+21+17 = 60

Then compute the expected frequencies as fe = (fc x fr)/n where fc is frequency of columns and fr is frequency of rows and n is total dreams.

Total number of females = 18+4+2 = 24

Total number of males = 4+17+15 = 36

For females low dreams(fe) = 22 x 24 / 60 = 8.8

medium dreams (fe) = 21 x 24/60 = 8.4

high dreams (fe) = 17 x 24/60 =6.8

Similarly for males low dreams (fe) = 22 x 36/60 = 13.2

medium dreams (fe) = 21 x 36 / 60 = 12.6

High dreams (fe) = 17 x 36 / 60 = 10.2

Lets compute the Chi-squared statistic as: x^2 = (f0 - fe)^2/fe

We find the residuals (fo - fe) for each cell and do the computation after which we get x^2 = 27.7

Now we compare this computed statistic (38.09) against the critical value and make a decision about your hypotheses. Here our hypothesis is rejected as conclude that there is a relationship between gender and dreams.

Type of transport where proteins channels help move molecules across the membrane. it is called by Facilitated diffusion

Facilitated diffusion is the passive movement of molecules down a concentration gradient. This is a selective process. In other words, the membrane selectively allows only molecules and ions to pass through. However, it prevents other molecules from crossing the membrane. As a result of facilitated diffusion, polar and charged molecules like carbohydrates, amino acids, nucleosides, and ions can traverse the plasma membrane. In general, two classes of proteins that mediate facilitated diffusion are distinguished.

Facilitated diffusion does not require high-energy molecules such as ATP. To transport chemicals across the plasma membrane, channel proteins and carrier proteins are used. Facilitated diffusion involves the movement of molecules from areas of high concentration to areas of low concentration.

The order of events from egg and sperm to embryo is Once the sperm fertilizes the egg, the zygote goes through mitosis.

The two gametes' membranes joining together to establish a channel that allows material to move from one cell to the other is the first critical event in fertilisation. Pollination, which occurs before fertilisation in advanced plants, is when pollen is delivered to and makes contact with the female gamete or macrospore. A single spermatozoon often penetrates the egg after fusion in mature animals. A cell (zygote) that can divide into new cells to create a person is the product of fertilization.

In the egg, multiple processes are started when two gametes fuse. One of them alters the egg membrane(s), making it impossible for many spermatozoons to adhere and penetrate. In animals where polyspermy—the presence of many spermatozoons in an egg—is the norm, only one spermatozoal nucleus actually fuses with the nucleus of the egg. Egg activation, which allows the egg to go through cell division, is the most significant outcome after fertilisation. The presence of a spermatozoon is not necessary for activation, though; during parthenogenesis, in which fertilization does not take place, physical and chemical factors may be used to activate an egg. Aphids, bees, and rotifers are examples of invertebrates that typically reproduce by parthenogenesis.
