Two substances are both reabsorbed in the kidneys are Glucose and salts. The correct option is a.

Glucose and salts are both substances that are reabsorbed in the kidneys. During the process of urine formation, the kidneys filter waste products, excess water, and solutes from the blood. However, some essential substances need to be retained in the body, so they are reabsorbed back into the bloodstream.

Glucose is a sugar and an important source of energy for the body. Normally, all filtered glucose in the kidney tubules is reabsorbed back into the bloodstream to maintain the body's glucose balance. The reabsorption of glucose occurs primarily in the proximal tubules of the nephrons.

Salts, such as sodium, potassium, and chloride, are essential electrolytes for various physiological processes in the body. The kidneys regulate the balance of these electrolytes by reabsorbing them from the filtrate back into the bloodstream. The reabsorption of salts occurs throughout the different segments of the renal tubules, primarily through active transport mechanisms.

Option b (glucose and starch), option c (glycogen and salts), and option d (glycogen and starch) are incorrect because starch and glycogen are not substances that are reabsorbed in the kidneys. Starch is a complex carbohydrate found in plant-based foods, while glycogen is a storage form of glucose in animals. These substances are typically broken down into glucose and then reabsorbed if necessary. However, in the context of kidney reabsorption, glucose refers to the direct reabsorption of filtered glucose molecules. Thus, the correct option is a.

Endothecium lies below epidermis is a true statement and the point at which funicle touches the ovule is raphe is also a true statement. Therefore, option A. a and d only is the correct answer.

Here's a brief explanation of each statement mentioned in the question:

a. Endothecium lies below epidermis: The endothecium is the innermost layer of the anther. It is a specialized tissue that provides support to the anther. It lies below the epidermis layer. Therefore, the statement is true.

b. Fusion of egg with male gamete is called apogamy: Apogamy is the development of the sporophyte without the occurrence of fertilization. It is the formation of a gametophyte from a somatic cell without the fusion of gametes. The fusion of an egg with a male gamete is called fertilization, not apogamy.

Therefore, the statement is false.

C. Synergids are haploids: Synergids are specialized cells found in the ovule of flowering plants. They are haploid cells that develop from the megaspore mother cell and are an essential part of the female gametophyte. Therefore, the statement is true.

D. Point at which funicle touches the ovule is raphe: The funicle is a stalk-like structure that attaches the ovule to the placenta in the ovary. The point where the funicle touches the ovule is called the hilum, not the raphe. The raphe is a ridge-like structure that runs along the side of the ovule. Therefore, the statement is false.

On chemical analysis, a particular protein was found to contain 438 amino acids. Then the number of peptide bonds present in this protein will be 437.

Proteins are the polymers made up of amino acid as the monomeric unit. These amino acids are joined together by the peptide bond. The proteins serve various functions inside then body like: structural, functional or catalytic.

Peptide bond is formed between two amino acids by the condensation reaction. The carboxylic group of one amino acid binds with the amino group of another amino acid, releasing water ad a by-product. The peptide bonds in a polypeptide is always one less than the total number of amino acids.

Compared with the fresh water zones, Marine zones occupy more space of the planet and are more salinity. Firstly most of the planet occupied by the oceans then the land are developed. They are more salinity because they have some chemicals in their sand that gives the salinity in water. Fresh water doesn't have salinity because the fresh water run off quickly and they didn't stop at any place. So, it has less salinity than Marine water.

Birds for example, if the trees are falling down, then they will most likely die. Fish, if the sun vaporizes all the water, they'll die too.

Answer: Male

Explanation:

The pelvis is narrow in males, the pubis arch is 90 degrees in angle. It is broad in case of females to support pregnancy and child birth. Also the pubis arch is more than 90 degrees in angle. An occipital protuberance is a region that connects the head to the neck and it is generally larger in males than in female. In males the forehead is sloping in the cranium whereas that in females it is vertical and flat.

Hence, the skeleton have the features that can be indicated towards the features of a male.

Exercise causes a rise in growth hormone (GH) levels, while a decrease in glucose levels or a rise in amino acid levels causes a decrease in GH levels. Growth hormone (GH) is a hormone secreted by the pituitary gland, which is located at the base of the brain. GH helps to stimulate growth, cell reproduction, and regeneration.

It also helps to regulate body composition, body fluids, muscle, and bone growth. GH levels are affected by various factors, such as exercise, sleep, and stress. Exercise has been found to increase GH levels. For example, research has shown that high-intensity exercise, such as weightlifting, can cause a significant increase in GH levels.

A decrease in glucose levels or a rise in amino acid levels, on the other hand, causes a decrease in GH levels. This is because GH production is inhibited by the presence of glucose in the bloodstream. When glucose levels are low, GH production is stimulated in order to maintain adequate blood sugar levels. However, when amino acid levels are high, GH production is inhibited because amino acids can be used as a source of energy, and there is no need to produce GH.

Answer: obligate anaerobe

Explanation: This experiment established that a bacterial isolate is subcultured into same medium in two different plates, but one is placed in an aerobic condition (i.e., presence of oxygen) while the other in an anaerobic condition (i.e., absence of oxygen), and the result shows that there was no growth on the plate incubated on the incubator shelf, whereas there was growth on the plate conditioned anaerobically.

This simply translates that the bacterium does not need oxygen to grow i.e., It’s an anaerobe. Moreso, assuming it grows on the two plates we would say it's a facultative anaerobe.

Thus, since it growth was only established on the plate with anaerobic condition, it's an obligate anaerobic bacterium.

Cellular storage deposits of glycogen, a free polysaccharide, could best be detected histologically using the Periodic acid-Schiff reaction.

Periodic acid-Schiff (PAS) staining is a technique for identifying mucosubstances such as glycoproteins, glycolipids, and mucins as well as polysaccharides like glycogen in tissues. The vicinal diols in these sugars are oxidized by the periodic acid reaction, typically causing the bond between two adjacent carbons not involved in glycosidic linkage or ring closure to break in the ring of the monosaccharide units that make up the long polysaccharides. This results in the formation of two aldehydes at the two free tips of each broken monosaccharide ring. The oxidation situation must be properly controlled to prevent additional oxidation of the aldehydes. The Schiff reagent then reacts with these aldehydes, producing a purple-magenta hue. Counterstains are frequently applied using an appropriate basic stain.

Tropomyosin is a protein that stabilizes existing actin microfilaments.

Tropomyosin is a two-stranded, alpha-helical coiled-coil protein that twists along the actin filament surface, spanning seven actin monomers. It stabilizes existing actin microfilaments by preventing actin polymerization and depolymerization.Tropomyosin is a long, thin, fibrous protein that binds to the actin molecule's grooves.

It stabilizes actin microfilaments by promoting the formation of microfilaments and inhibiting the depolymerization of microfilaments by sterically blocking actin filament association. Tropomyosin's coiled coil binds to a continuous groove on the surface of actin monomers, which serves as a scaffold for troponin to attach to tropomyosin.The tropomyosin molecule stabilizes the actin filament by preventing the myosin head from binding to the actin monomers, causing muscle contraction.
