Fermentation of lactic acid occurs when cells make ATP without having a supply of oxygen.

Oxygen abundance permits aerobic respiration to proceed. This permits glucose to be totally oxidized to produce an abundance of energy. In contrast, when oxygen is low, cells switch to a significantly less efficient type of energy production. This process is called anaerobic respiration.

Glycolysis is the first step in the fermentation process, but fermentation does not involve the second and third stages of aerobic cellular respiration (the Krebs cycle and oxidative phosphorylation). Glycolysis results in the production of two additional ATP molecules on top of the reduction of two NAD+ electron carriers into two NADH molecules. It is important that NADH be oxidized once more so that glycolysis may proceed and cells can keep producing two copies of ATP. Due to the absence of oxygen, the cells are unable to undergo oxidative phosphorylation, which prevents them from producing more than two ATP during the fermentation process.

There are two different kinds of fermentation: alcoholic fermentation and lactic acid fermentation. Only the fermentation of lactic acid can take place within our cells. The pyruvate produced by glycolysis is converted to lactic acid in the process of lactic acid fermentation in the absence of oxygen.

The mean is greater than the median, the distribution of tail length is positively skewed. The median is more relevant in this case as it is not affected by the outliers.

The descriptive statistics of the data is shown below. Rounded to 2 decimal places:

Mean tail length: \(e. \bar{x}\) =95.50 mm4.

Median tail length: f. Q2=95.50 mm

IQR: Q3-Q1 = 12.50 mm

Variance: d. s²=46.80 mm²

SD: s=6.84 mm.

The mean is greater than the median of the tail length data. This implies that the data is positively skewed. This is because the mean is affected by outliers, which pulls it in the direction of the outliers. Hence, since the mean is greater than the median, the data is skewed towards the higher values.

The median measure is more relevant for this data because of the presence of outliers in the data, which has caused the mean to be influenced by the outliers, thus pulling it towards the higher side. So, the median will be more representative of the typical tail length of the population without being affected by the outliers. The mean, on the other hand, is an appropriate measure when the data is normally distributed, and there are no outliers in the data.

Some microbes can gain access to the normally sterile central nervous system (CNS) through several routes like hematogenous spread, direct extension, trauma or surgery, congenital transmission, and nvasive procedures.

1. Hematogenous spread: Microbes can enter the CNS through the bloodstream. They may initially infect another site in the body, such as the respiratory tract, urinary tract, or skin, and then disseminate through the bloodstream to reach the CNS. Examples of microbes that can spread hematogenously to the CNS include bacteria like Streptococcus pneumoniae and Neisseria meningitidis.

2. Direct extension: In some cases, infections in nearby structures or tissues can extend directly into the CNS. This can occur when microbes invade the structures surrounding the CNS, such as the sinuses, middle ear, or skull, and then spread into the brain or spinal cord. For instance, untreated sinusitis can lead to the spread of bacteria to the meninges, causing meningitis.

3. Trauma or surgery: Physical trauma, such as a head injury or penetrating wounds, can provide a direct route for microbes to enter the CNS. Surgical procedures involving the brain or spinal cord also carry a risk of introducing microbes into the CNS.

4. Congenital transmission: Some microbes can be transmitted from an infected mother to her baby during pregnancy or childbirth. For example, the bacterium group B Streptococcus can be transmitted from a colonized mother to the newborn, leading to neonatal meningitis.

5. Invasive procedures: Invasive medical procedures, such as lumbar puncture or ventricular shunt placement, which involve the insertion of needles or catheters into the CNS, carry a risk of introducing microbes into the normally sterile environment.

The substance, needed for protein synthesis, that is carried into a leaf from the stem is nitrate. Nitrate is an essential nutrient that plants use to produce amino acids and proteins. It is a part of the nitrogen cycle and is used in chloroplasts to create essential proteins.Option B is correct

The process of protein synthesis takes place in chloroplasts of the leaves of plants where nitrogen, along with other elements, is utilized to produce proteins. Nitrogen, in the form of nitrate, is an essential element required by the plant for the synthesis of amino acids and proteins.

Plants obtain nitrate through the soil from the water they absorb through their roots. It is transported from the roots to the leaves through the xylem vessels, which form a continuous pipeline from the roots to the stem and leaves of the plant. The process of protein synthesis is important for the growth and development of plants.

It is essential for the production of enzymes, hormones, and structural components such as cell walls and membranes. Nitrate is, therefore, a critical substance for protein synthesis and the growth and development of plants. Option B is correct

Adaptive immunity utilizes memory cells and antibodies to provide a specific and enhanced response to a pathogen upon second exposure, while innate immunity relies on general defenses to respond to pathogens.

The immune system is responsible for defending the body against pathogens such as bacteria, viruses, and parasites. It consists of two primary components: innate immunity and adaptive immunity.

Innate immunity is the first line of defense and provides immediate, nonspecific protection against a wide range of pathogens. It includes physical barriers like the skin, as well as cellular components such as macrophages and natural killer cells that can engulf or destroy pathogens.

Adaptive immunity, on the other hand, is a specific and highly targeted response that develops over time. It involves the recognition of specific pathogens and the production of memory cells and antibodies to fight off future infections. During the first exposure to a pathogen, adaptive immunity takes time to mount a response.

However, once the pathogen is encountered again, memory cells recognize it quickly, leading to a faster and more effective immune response. This process is known as immunological memory.

In summary, adaptive immunity utilizes memory cells and antibodies to provide a specific and enhanced response upon second exposure to a pathogen. Innate immunity, on the other hand, relies on general defenses to respond to pathogens without the specificity and memory of adaptive immunity.

The feature that distinguishes DNA polymerases from RNA polymerases is that the latter requires both a template and a primer.

DNA polymerases are enzymes involved in DNA replication and repair, while RNA polymerases are responsible for synthesizing RNA molecules. One key difference between these polymerases is the requirement for a template and a primer. DNA polymerases require a template strand, which serves as a guide for synthesizing a complementary DNA strand, and a primer, which provides an initial starting point for DNA synthesis.

In contrast, RNA polymerases only require a template strand, as they can initiate RNA synthesis de novo without the need for a primer. RNA polymerases are capable of binding to specific DNA sequences, called promoters, and initiating RNA synthesis from the template DNA strand. This distinction in the requirement for a primer is a fundamental difference between DNA polymerases and RNA polymerases, highlighting their distinct roles in DNA and RNA synthesis processes.

Answer:

Most plants absorb water through the roots. Land plants get almost all the water they need from the soil. The amount of water available in the soil varies according to its porosity and its degree of desiccation. A large proportion of water is retained by cohesion forces between the particles. When the water is in the roots it moves inside the plant through the xylem. The xylem is the transport system that carries water to the entire plant.

Explanation:

The xylem connects all parts of the plants (from the roots to the stems and from there to the leaves). The water in the xylem creates a gigantic chain of molecules that adhere to each other, just like they adhere to the xylem. For plants to transport water from roots to leaves and use it in other functions, other structures called stomata are required. Stomata are small pores in leaves that plants can open and close as needed. If they open, the water moves out of the stomata and evaporates into the air. This occurs because the water molecules diffuse, from the humid air inside the leaf, to the much drier air surrounding the leaf. The loss of water through the stomata together with the high cohesion of the water particles and the resistance of the root "stress" the water column. This causes the water potential of the roots to decrease and the surrounding water enters the plant.Each stoma is made up of two occlusive cells. When these cells are turgid, a hole opens between them; when the cells relax, the hole disappears. The turgor pressure depends directly on the inlet or outlet of the water. This movement, in turn, depends on the concentration of solutes within the cell.

Your nerves somehow allow this signal to pass through and, like magic, it causes that large muscle to contract.   If it's okay, we'll concentrate on it as the question directly refers to the muscular contraction. We move ahead to the motor neuron, where the brain's action potential has already reached the muscle. Motor units, which are made up of an upper and a lower motor neuron, are used to control muscles. The top motor neurons, or the neuron that transmits signals from the brain, are represented by the tracts above. After connecting to lower motor neurons, upper motor neurons link to the muscle. The basic structure of your muscles is fibers inside fibers inside fibers. Sarcomeres, the smallest unit, are made up of sections that are separated by Z-lines. We have two filaments, actin and myosin, between the Z-lines. The M-line is where Myosin is connected, while Actin is a long, thin filament attached to the Z-line. The actin will be pulled by the myosin, which will cause the Z-lines to constrict inward toward the M-line. The bigger structures will follow if many of these tiny fibers do this at once, triggering the contraction of the entire muscle. The Sliding Filament Model of contraction is used to describe this.

A single Actin and Myosin pair appears quite similar if we zoom in on it. Myosin and actin do not contact when your muscles are at rest, yet they have a strong attraction for one another (they really want to touch). If not for two proteins (tropomyosin and troponin) linked to the Actin filament, they would touch. As we are still awaiting a signal, we slightly zoom out.

An action potential is sent by the lower motor neuron, which causes Acetylcholine to be released into the synapses. This results in an inflow of sodium, which changes the voltage and spreads the signal.

The action potential is no longer in the neuron but rather within the muscle. The Sarcolemma is struck by the action potential as it travels through the muscle cells.

The Sarcolemma has tubes that penetrate the cell deeply (T-Tubules). The Action Potential is sent at the Sarcomeres via these tubes.

Calcium is continually being pumped out of the cell by the Sarcoplasmic Reticulum, which houses the sarcomeres (these pumps use ATP as energy). Additionally, it has voltage-gated calcium channels that are still closed that line it.

The Voltage Gated Calcium channels open when the T-Tubules produce an action potential, allowing calcium to flood the cell.

The two proteins that surround the actin are now activated by calcium. When calcium attaches to troponin, a shape shift occurs (as proteins do when they bind). The active strands are revealed as the troponin pulls tropomyosin in its direction.

Now that the Actin sites are revealed, the Myosin is free to bind to them. However, myosin, which used some ATP and broke it down into ADP and phosphate, is the only protein that can actually do this. This myosin, which has been "charged," extends. It remains put, clinging to ADP+Phosphate like a loaded weapon.

As a result, the two Z-lines are pulled toward the centre by the Myosin, and the sarcomere contracts.

Since the Sarcoplasmic Reticulum's calcium pumps are actively pumping calcium out, calcium ultimately dissociates from Troponin. Actin is rendered unavailable to myosin as a result of the protection being reset. The fun is gone now because Myosin can no longer link to the actin, and when an action potential occurs, the cycle restarts.

And that’s how a signal from the nervous system, an action potential, can cause a muscle to contract. Isn’t nature cool?
