Describe the process of photosynthesis and cellular respiration.

1 answer:

8 0

Photosynthesis and respiration are the opposite processes, basically speaking. Photosynthesis gets its name from light-dependent reactions, which involve photolysis of water (breakdown of H2O into oxygen and hydrogen), and then combining hydrogen with small sugar molecules, while also incorporating CO2 into them.

Point where crossing over takes place between chromatids of the homologous chromosomes during prophase 1

Free_Kalibri [48]

Answer:

Crossing over occurs during prophase I of meiosis before tetrads are aligned along the equator in metaphase I.

Explanation:

When chromatids "cross over," homologous chromosomes trade pieces of genetic material, resulting in novel combinations of alleles, though the same genes are still present. Crossing over occurs during prophase I of meiosis before tetrads are aligned along the equator in metaphase I.

Imagine these two elements, element A and element B are solids. The two elements are poured into a beaker and mixed. Illustrate

Kryger [21]

Chromatography is a simple technique in principle, it remains the most important method for the separation of mixtures into its components. It is quite versatile for it can be used to separate mixtures of solids.

Explanation:

The two elements of chromatography are the stationary phase and the mobile phase. There are many choices of stationary phases, some being alumina, silica, and even paper. The mobile phase, in liquid chromatography, can also vary. It is often either a solvent or a mixture of solvents and is often referred to as the eluant.
A careful choice of eluting solvent helps to make the separation more successful. The mixture is placed on the stationary phase. The eluant passes over the mixture and continues to pass through the stationary phase carrying along the components of the mixture.
Chromatography is used in industrial processes to purify chemicals, test for trace amounts of substances, separate chiral compounds and test products for quality control. Chromatography is the physical process by which complex mixtures are separated or analyzed.
Chromatography is based on the principle where molecules in mixture applied onto the surface or into the solid, and fluid stationary phase (stable phase) is separating from each other while moving with the aid of a mobile phase

ololo11 [35]

Answer:

If the calcium levels in blood increases, then there is increase in blood glucose level.

Explanation:

Calcium in blood plays a vital role of homeostasis in regards to level of secretion of insulin. If the calcium level is altered, the homeostasis mechanism is hampered. Several researches have shown that alteration of serum calcium level affects the metabolism process of carbohydrate and makes the person vulnerable to risks of diabetes mellitus and associated complications. Hence during calcium supplementation, the person's blood glucose level must be considered.
