Answer: D) chromosomes and genes
Chromosomes are long thread like structures which are found inside the nucleus of the living organisms. These chromosomes consists of small segment units called as genes. The genes control the genetic information which when expresses result in the production of specialized functional proteins. The gene is a hereditary material which is passed from the parents to the offsprings after reproduction. The expression of genes in the new organisms results in the expression of characters which were found to be similar in both parents and offsprings but some changes occur due genetic variation. Therefore, organisms exhibit anatomical similarities in features due to chromosomes and genes.
Chromosomes and genes determines the similarities in anatomical features among organisms. The correct option is D.
Thus, Chromosomes, which resemble lengthy threads, are found inside the nucleus of living things. The little segment units that make up these chromosomes are known as genes.
The genes regulate the genetic material, which, when expressed, leads to the creation of certain, useful proteins. The gene is a genetic component that, during reproduction, is transferred from parents to children.
Characters that were determined to be comparable in both parents and children are expressed by genes in new creatures, however some modifications take place owing to genetic diversity. The correct option is D.

Well the soil classification is usually done on the basis of particle sizes and composition of soil.
Clay usually consists of particles less than 0.075 mm in size. It is a sticky soil and shows great changes in volume with variation in its water contact. It also shows considerable strength when air dried.
Silt has larger particles than clay and are mainly inorganic in nature. The particle size is less than 0.075mm and exhibits slightly plastic or non plastic behaviour.
Humus is soil consisting of dead and decaying organic matter. It is mainly organic in content but some inorganic particles may be mixed in it. The top soil in a tropical forest may be considered as humus.
Sand is the largest particle in soil among the options provided. Particles in soil are categorized into three groups: sand, silt, and clay, with sand having the largest particle size. Humus, though a soil component, is not a soil particle but decomposed organic material.
The largest particle in soil, out of the options given, is sand. In soils, particles are categorized into three main groups according to their sizes: sand, silt, and clay. Sand has the largest particles, typically between 0.05mm and 2mm in diameter. On the other hand, silt particles are smaller than sand, typically between 0.002mm and 0.05mm, and clay has the smallest, less than 0.002mm. Humus, another component of soil but not a soil particle, is decomposed organic material that contributes to the nutrient content of the soil.

Answer: Loess is the fine grained material that has been transported and deposited by the wind.The answer isA.
Explanation:
Since the wind can carry these types of material (find grained) father than sand, and also higher up, they are generally found very far from their original place of origin.
Loess is no larger than 50 micrometers in size. It is coarse in texture like clay, but finer than a grain of salt.
I think it brings to the warm places cold air and to cold places it brings warm air
