O A. The mother feels the fetus move for the first time.
B. The fetus begins rhythmic breathing movements.
C. The fetus's hands and feet appear
D. The fetus begins to form teeth.
During the second trimester of a woman's pregnancy, the mother starts feeling the fetus's movements for the first time and the fetus's hands and feet start to appear. Therefore, the correct statements are option A and option C.
The second trimester period ranges from 13 weeks to 27 weeks and is considered to be the middle stage of pregnancy. During this period, significant growth and development can be seen in the developing fetus, and some organs get fully developed.
During the second trimester, any health issues associated with the fetus can also be detected. The second trimester is a very important stage of pregnancy where the mother and her fetus both experiences a significant change.
During the second trimester of pregnancy, the fetus's hands and feet begin to appear. However, the mother also starts feeling the movements of the fetus usually during the second trimester. However, the teeth fully form after birth.

Answer:
a. the mother feels the fetus move for the first time
Explanation:
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.

Explanation:
Answer:
Option C , I and II only
Explanation:
The study conducted is done only for people or organisations that either started a compost pile or who want to start a compost pile. Thus result III is not at all a valid question for the study conducted.
However, there can be question related to the result of experiments clarifying the quantity of additives used in the experiment for example why only 10 Kg of dry water, why not to add more than 1 L of water , why only water is to be added why not some other solvent etc. Thus question I is a valid question.
Also , question II is valid as it asks about expanding the scope of experiment from one type of organic material to all other type of organic matter in the compost.
There fore both question I and II are valid question and thus option C , is correct.
