The main purpose of a forester is to identify land for timber harvesting.

It was identified that a disease resistance locus in Arabidopsis is functionally homologous to the rpg1 locus of soyabean.

Using an avirulence gene that was previously cloned from a pathogen that does not affect Arabidopsis, the new disease resistance locus RPS3 in that plant was discovered. Pseudomonas syringae pv. tomato strain that is virulent on Arabidopsis was transformed with the avrB avirulence gene from the soybean pathogen, and conversion to avirulence was tested on Arabidopsis plants. On most Arabidopsis ecotypes, but not all, the avrB gene was avirulence active. Of the 53 ecotypes that were tested, eight were susceptible and 45 were resistant to a P. syringae pv. tomato strain that carried avrB. Crosses between the susceptible ecotype Bla-2 and the resistant ecotype Col-0 were used to study the transmission of this resistance. The ratio of resistant to susceptible F2 plants from this cross was almost 3:1, showing that ecotype Col-0's solitary dominant locus, RPS3, controls resistance to P. syringae that expresses avrB. RPS3 was located on chromosome 3 near markers M583 and G4523 and or = 1 cM from RPM1, another disease resistance locus, using RFLP analysis. The locus RPG1 in soybean regulates resistance to P. syringae strains that possess avrB. As a result, RPG1 and RPS3 both provide resistance to avrB-specific diseases, raising the possibility that these genes are homologs.

Ribosomes are involved in protein synthesis. Almost all enzymes are proteins. Hence, ribosomes make enzymes too. Chemical structure of hormones is diverse including steroid, eicosanoids, amino acids derivatives, proteins and peptides. Hence, except proteinous hormones, all other types of hormones cannot be synthesized by ribosomes.Ribosomes are not involved in starch manufacture.Was this answer helpful?

Based on the matrix Phylogeny 2  tree represents the most parsimonious explanation of relatedness among these species

The study of relationships and the evolutionary history of various groupings of species is known as phylogeny. The goal of phylogeny is to reconstruct the evolutionary course of all species on Earth. It is based on the phylogenetic theory, which holds that all living things descended from a single common ancestor. A phylogenetic tree is a visual representation of how species are related to one another. The comparison of genetic and anatomical similarities shows that relationships are based on shared traits.

Thyroxine hormone is a hormone that plays an important role in regulating metabolic rate and hence body temperature.

Thyroxine is a hormone that is important in regulating body's metabolism and thus body temperature. Because it is released into the bloodstream by the thyroid gland, this hormone is also known as thyroid hormone. Thyroxine (T4) is the inactive form of thyroid hormone that is later transformed into active triiodothyronine (T3).

Thyroxine and triiodothyronine are two major hormones released into the bloodstream by the thyroid gland. Thyroid hormones stimulate all cells and regulate biological processes like metabolic activity, development, reproduction, and growth.

Epithelial tissue lines the cavities and surfaces of organs and blood arteries throughout the animal body, whereas connective tissue supports, links, and divides many types of tissues and organs in the body. This is the main distinction between epithelial and connective tissue.

Cell arrangement: The physical properties of the Epithelial tissue affect how the connective tissue is organized. There are different arrangements of epithelial cells, such as squamous, cuboidal, and columnar, that organize as simple, stratified, pseudostratified, and transitional. Since epithelial cells form from ectoderm, mesoderm, and endoderm, this explains why epithelia line body cavities.

The interference pattern seen when light passes through narrow, closely spaced slits, is due to Diffraction:

Diffraction is a light phenomenon that occurs when light strikes an impediment or travels through the slit. This results in a light pattern known as interference.

When light goes through a slit or hits an object, it creates a series of patterns known as interference patterns. The light bends through the corners of the barriers or passes through a slit that might behave as an obstruction. The pattern is caused by the diffraction phenomenon and involves the form of the slit in it. Diffraction is the sole phenomena that causes interference patterns, rather than reflection, refraction, dispersion, or deflection. Thomas Young's work on limited double-slit geometry produced observable interference effects and was the basis for diffraction.

Anaphylaxis caused by stinging insects is typically an allergic reaction to the injected poison, irritating toxin, and deadly venom rather than the bite or sting itself. The correct answer is option(D)i.e, All of these answers are correct.

Anaphylaxis can be fatal if untreated or improperly treated. Even if your symptoms disappear pretty quickly, they may return a few hours later, worsen, and become more challenging to cure.

People who have allergies typically experience mild to moderate symptoms, such as watery eyes, a runny nose, or a rash. Anaphylaxis, a serious allergic reaction that can be fatal, can however occasionally result from exposure to an allergen. When too many chemicals are released at once, shock results, which is a severe reaction

The most frequent triggers within these groups were wasp and bee stings (n = 1460 and 412, respectively), legumes (n = 241), animal proteins (n = 225), and analgesics (n = 277). In children, peanuts, cow milk, and hen's eggs were the most common food allergens to cause anaphylaxis; in adults, it was wheat and shellfish. When you have anaphylaxis, your immune system releases a rush of chemicals that can put you in shock and cause your blood pressure to drop and your airways to constrict.
