Answer:
true
Explanation:
Carbohydrates, like all organic molecules, always contain carbon (C) and hydrogen (H) atoms. Carbohydrate molecules are characterized by the presence of the atomic grouping H-C-OH, in which the ratio of hydrogen atoms (H) to oxygen atoms (O) is approximately 2:1. Because this ratio is the same as the ratio in water, the name “hydrates of carbon” seems appropriate. Carbohydrates first and foremost function for quick, short-term energy storage in all organisms, including humans.
Answer:
The aim of question is to know about molarity of ammonia solution 25% . ... If you have 17 g NH3 in 1000 ml H2O, you have a 1M NH3. ... Can you not titrate it using standardised acid? ... Mass concentration of ammonia in stock solution = ... So 1 M means 35.04gr in a liter of water and because the solution ...

Explanation:
Answer:
The correct labels are :
Label A prophase
Label B metaphase
Label C anaphase
label D telophase
Explanation:
Mitosis, a method of cell division which complete in four different phases. These phases are prophase, metaphase, anaphase and telophase. In the given question the correct labels are: A-prophase; B-metaphase; C-anaphase and D-telophase. Mitotic division is begins with prophase in which chromatin threads condense and called chromosomes. During metaphase all the chromosomes get arranged in the central plane. In the anaphase, the sister chromatids of each chromosome gets separated and move to the opposite pole. In the telophase the spindle breaks from the chromatids and begins to disappear. The nuclear membrane starts to form around each of the daughter chromosomes.
Answer:
The correct answer is option D.
Explanation:
Dynamic equilibrium refers to the sense, which interprets angular acceleration in the three-axis of rotation that when combined provides a sense of equilibrium when movement takes place. The receptors for dynamic equilibrium are known as ampulla, maculae are the receptors of static equilibrium.
The movement of the head does stimulate dynamic equilibrium receptors, as these receptors are situated in the inner ear that moves with the head. The receptors for dynamic equilibrium are situated in the semicircular canals. The receptors for dynamic equilibrium react to rotational forces, as the receptors are located on the three-axis, thus, they can detect rotation, that is, angular momentum.
