The answer you are looking for is true.
B. Viruses are not living.
C. Viruses have organelles.
D. Viruses can reproduce by themselves.
B. Viruses are not living.
A virus is nothing more than a packet of genetic material that does not display the characteristics of living organisms.
Viruses are not living and they do not have organelles or produce their own energy.
The correct statement regarding viruses is B. Viruses are not living.
Viruses are considered non-living because they lack the necessary characteristics to be classified as living organisms. While they can infect and replicate within a host cell, they are unable to carry out essential life processes on their own.
Unlike cells, viruses do not have organelles and cannot produce their own energy. They are composed of genetic material surrounded by a protein coat, and they rely on host cells to replicate.

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.

A downward arching rock layer is called syncline.
Explanation:
Syncline and anticline are words used to design folds based on the analogous ages of folded rock layers. A syncline is a fold in which the modern rocks happen in the core of a fold. Where rock layers have been changed prior to folding, such as by folding about a giant fold with a shallowly inclined axial surface, the dearest rocks now occur in the core of folds where layers slide towards the fold axis.
A downward arching rocklayer is called a syncline. It is a type of fold that is characterized by its downward-facing axis.
Synclines are typically formed when sedimentary rocks are subjected to compressional forces. The compressional forces cause the rocks to bend, forming the downward-facing axis.
Synclines are often found in sedimentary basins, which are areas where sediment has accumulated over time. The sediment is typically deposited in horizontal layers, but the compressional forces can cause the layers to bend, forming synclines.
Synclines can be identified by their characteristic shape. They are typically bowl-shaped, with the axis of the fold running through the center of the bowl.
