No, high percentage of Sand particles don't contribute to high porosity. Water in sandy soil just passes through it because of larger pore diameter.

A high percentage of sand particles contributes to low porosity of soils.

Porosity is a characteristic that determines the level of pores in soils.

When it comes to porosity, the component of soil with the highest is clay, followed by silt, and then sand.

Sand particles are large and leave little pores as compared to the particles of silt and clay which are smaller.

Thus, the more sand particles in soils, the lower the porosity.

Answer:

(a) The structures labelled A and B in the diagram are:

A - Capillaries

B - Alveoli

(1) Healthy lung

(2) Diseased lung

The disease shown in the diagram is emphysema.

(3) Explanation:

Emphysema is a respiratory disease that affects the alveoli, the tiny air sacs in the lungs responsible for the exchange of oxygen and carbon dioxide between the lungs and the bloodstream. In emphysema, the walls of the alveoli are damaged, leading to the formation of larger, less efficient air spaces. This causes a reduction in the surface area available for gas exchange, leading to impaired breathing and reduced oxygen supply to the body.

As the walls of the alveoli break down, the lungs lose their elasticity and become less able to expel air. This results in a buildup of air in the lungs, which can cause shortness of breath and other respiratory symptoms. In addition, the capillaries around the alveoli may become damaged, leading to reduced blood flow to the lungs and further reducing the efficiency of gas exchange.

Overall, emphysema reduces the efficiency of the process of gaseous exchange in the lungs by reducing the surface area available for gas exchange and impairing the ability of the lungs to expel air. This can lead to reduced oxygen supply to the body and other respiratory symptoms.

The correct sequence of events in cellular respiration is option a: glycolysis, citric acid cycle, electron transport chain.

During cellular respiration, glucose is broken down to produce energy in the form of ATP. The process starts with glycolysis, which occurs in the cytoplasm and involves the breakdown of glucose into pyruvate molecules. Glycolysis generates a small amount of ATP and NADH.

The pyruvate molecules produced in glycolysis enter the mitochondria, where the citric acid cycle, also known as the Krebs cycle, takes place. In this cycle, the pyruvate is further broken down, releasing carbon dioxide and generating NADH and FADH2 as electron carriers. The citric acid cycle also produces a small amount of ATP.

The electron carriers NADH and FADH2 then participate in the electron transport chain, which is located in the inner membrane of the mitochondria. In the electron transport chain, the electrons from NADH and FADH2 are transferred through a series of protein complexes, creating a flow of electrons that drives the synthesis of ATP. This process is known as oxidative phosphorylation.

Therefore, the correct sequence of events in cellular respiration is glycolysis, citric acid cycle, and electron transport chain, as stated in option a.

The chemical reaction is sped up.

The activation energy is lowered.

Explanation:

When enzymes are added to a chemical reaction, they lower the activation energy needed in the reaction.

In return, that also speeds up the chemical reaction, since less energy is needed to start it.

Enzymes do not stop chemical reactions, and enzymes can also be reused, so they are not used up.

To characterize Patient B's karyotype, I would use the International System for Human Cytogenetic Nomenclature (ISCN).

Begin by obtaining a sample of the patient's chromosomes from nucleated cells in their blood. This can be done through a blood draw or other suitable methods.

Prepare the chromosomes for analysis by staining them to create a banding pattern. This pattern helps in identifying and distinguishing individual chromosomes.

Examine the stained chromosomes under a microscope and capture high-resolution images of the metaphase spread. This ensures clear visualization of each chromosome.

Analyze the chromosome images and identify any structural abnormalities, such as deletions, duplications, inversions, or translocations. Pay close attention to the sex chromosomes, as abnormalities in these can be relevant to the patient's infertility.

Determine the number of chromosomes present in the patient's karyotype. In a normal human karyotype, there are 46 chromosomes, including 22 pairs of autosomes and 1 pair of sex chromosomes.

Assign a karyotype designation to the patient based on the observed chromosome abnormalities. This involves using the International System for Human Cytogenetic Nomenclature (ISCN), which provides a standardized notation for describing chromosomal variations.

Document the patient's karyotype using the ISCN notation, indicating the specific abnormalities observed and their locations on the chromosomes.

Interpret the findings of the karyotype analysis in the context of the patient's infertility. Consult with a geneticist or reproductive specialist to determine if the identified chromosomal abnormalities could be contributing to the patient's condition.
