what type of bacteria could you identify by using the emb plates, and why would these bacteria be of concern for human health?

Soil air supplies plants and microorganisms with two vital gases for life processes: oxygen (O2) and carbon dioxide (CO2).

Plants and microorganisms require oxygen (O2) for respiration, the process by which cells generate energy. During respiration, organic molecules are broken down in the presence of oxygen to release energy. Oxygen is obtained from the soil air through tiny air pockets or air-filled spaces in the soil. The roots of plants and the surrounding soil microorganisms extract oxygen from the soil air, enabling them to carry out aerobic respiration and sustain their metabolic activities.

On the other hand, carbon dioxide (CO2) is essential for photosynthesis in plants. During photosynthesis, plants use carbon dioxide, along with sunlight and water, to produce glucose and oxygen. The carbon dioxide needed for photosynthesis is obtained by plants through the stomata in their leaves, which open up to allow gas exchange with the atmosphere. In the soil, microorganisms also require carbon dioxide for various metabolic processes.

Therefore, soil air plays a critical role in providing plants and microorganisms with the necessary oxygen for respiration and carbon dioxide for photosynthesis and other life processes.

Simple diffusion occurs passively without the need for energy or protein assistance, while facilitated diffusion utilizes specific proteins to facilitate the movement of solutes across the membrane, still without energy input.

Simple diffusion and facilitated diffusion are both passive processes that involve the movement of solutes across a membrane, but they differ in terms of energy requirement and the mechanism of solute movement.

In simple diffusion, solutes move down their concentration gradient from an area of higher concentration to an area of lower concentration, without the need for energy input. This process relies solely on the random thermal motion of molecules, allowing solutes to pass directly through the lipid bilayer of the membrane.

In facilitated diffusion, on the other hand, specific membrane proteins called transporters or channels facilitate the movement of solutes across the membrane. Although facilitated diffusion does not require energy, it does rely on the presence of these protein transporters to assist in the movement of solutes that cannot pass through the lipid bilayer easily.

Answer:

Antibiotic resistance is an act of evolution via natural selection. The antibiotic action is an environmental pressure: those bacteria which have mutation allowing them to survive and re-produce

Explanation:

A variation in the properties of an organism over a period of time is called evolution.

Antibiotic resistance can transpire naturally or due to progression.

This type of endurance occurs so that the bacteria can persist and proliferate in the changed conditions.

Fluoroquinolones (FQ) modify the enzymes like DNA gyrase and topoisomerase IV.

The bacteria in order to survive from this antibiotic adapted mechanism so that the use of antibiotics would not hinder their reproduction mode and hence they will be able to survive.

Cell A is more efficient at exchanging substances due to larger surface area to volume ratio.

Cell A is more efficient at exchanging substances with the surrounding environment than cell B because it has the larger surface-area-to-volume ratio. Larger surface area of the cell exchanges more substances with the surrounding environment.

While on the other hand, lower surface area of the cell exchanges less materials with the environment so we can conclude that cell A is more efficient at exchanging substances due to larger surface area to volume ratio.

Sex-linked traits are the characteristics that are determined by genes located on sex chromosomes. Inheritance patterns for these traits can be different for males and females, as X and Y chromosomes differ. One of the example of sex-linked trait is color blindness, which is mostly seen in males.

Females can get X-linked recessive disorder, but this is rare. An abnormal gene on X chromosome from each parent would be required, as female has two X chromosomes.

There is an equal chance that the spinner will stop on either the red or blue segment.

Probability theory is the mathematical study of the numerical representation of the probability that an event will take place or a statement will be true. Probability is measured on a scale from 0 to 1, with 0 denoting complete impossibility and 1 denoting absolute certainty.

Generally, the equation for the Probability of getting of  spinner landing is  mathematically given as

\(P= \frac{ total \ number \ of \ favourable \ outcome}{total \ number \ of \ outcome }\)

The blood clot-dissolving enzyme vampire bats use while feeding is Desmoteplase, DSPA-alpha-1. Desmoteplase functions by activating plasminogen.

Plasminogen is in the blood in an inactive form and must be activated to dissolve blood clots. Desmoteplase activates plasminogen by cleaving it at a specific site, resulting in plasmin formation. Plasmin then breaks down the fibrin protein in blood clots, leading to their dissolution.

Blood clots, also known as thrombi, are clumps of blood cells and proteins that form in response to injury or other conditions that cause damage to blood vessels. Blood clotting is a natural process that helps to stop bleeding and prevent blood loss.

Joints involving a cartilage disc at the junction of 2 bones are called "synovial joints."

Synovial joints are characterized by the presence of a cartilage disc, known as an articular disc or meniscus, located between the articulating surfaces of two bones. These joints allow for smooth and controlled movement, providing stability and reducing friction between the bones. Examples of synovial joints include the temporomandibular joint (TMJ) in the jaw, the sternoclavicular joint in the shoulder, and the knee joint. The articular disc in these joints acts as a cushion, absorbing shock and facilitating joint movement.
