General Science Questions

Inhaling of oxygen and releasing of carbon dioxide to make our living is the process called as respiration. We know that, air is a mixture several gases like 78% of nitrogen, 21% of oxygen and several other gases with watervapour.

Hence, Oxygen is essential for respiration process.

Glycolysis involves the breaking down of a sugar into more manageable compounds in order to produce energy.

The net end products of glycolysis are two Pyruvate, two NADH, and two ATP.

The term for classifying and grouping organisms is Taxonomy. It is the science of defining and naming groups of biological organisms on the basis of shared characteristics.

Oxygen released during photosynthesis comes from splitting of water.

Water possess intermolecular hydrogen bonding in the condensed phase.

Hence, the given statement 'There is extensive intramolecular hydrogen bonding in the condensed phase.' about water is FALSE.

The main goals of psychology are four. They are::

1. To describe,

2. To explain,

3. To predict (and)

4. To control the behavior and mental processes of others.

When water is cooled from 4°C to 0°C, its density decreases.

When water cools from 4°C to 0°C, ice crystals begin to form because the water is approaching its freezing point. When water freezes, the water molecules form a lattice that increases the volume. As a result, the density decreases. This is why ice will float on top of water; ice has a lower density than the water.

A clade is a group of ancestral species and all its descendants. Hence it is a branch of one same species and so monophyletic.
