how do you prove the fact that green plant releases Oxygen gas in the process of photosynthesis explain the experiment.
Answer:
Aim : To prove that oxygen is produced during photosynthesis
Procedure : Place water plant in a beaker containing pond water.
Cover the plant with short stemmed funnel.Invert the test tube full of water and cover the stem of the funnel.While placing the test tube, ensure that the level of the water in beaker is above the level of stem of funnel.Expose the apparatus to the sunlight.
After few hours, gas bubbles will form and collect in the test tube.Test the gas in the test tube.
A glowing splinter bursts into the flame shows the presence of oxygen.
Observation: Gas bubbles in a test tube.
Result: Presence of oxygen.
Conclusion: Formation of gas bubbles prove that oxygen is produced by the green plants
Describe the convalent bond including providing examples of compounds formed through each type of bond ?
Answer:
is a chemical bond between two non-metal atoms. Like Hydrogen, Oxygen, Carbon are just few.
There is a covalent bond between the oxygen and each hydrogen in a water molecule (H 2 O). Each of the covalent bonds contains two electrons, one from a hydrogen atom and one from the oxygen atom.
Explanation:
Water or Co2 is a covalent bond that be either polar which has a negative charge and positive charge like water that has one negative oxygen and two positive hydrogen. and non polar like Carbon bonding with carbon is both positive.

What type of genotype does a person with a recessive genetic disorder have?
Answer:
one mutated recessive one and one mutated dominant gene
Explanation: These disorders are usually passed on by two carriers. Their health is rarely affected, but they have one mutated gene (recessive gene) and one normal gene (dominant gene) for the condition.
Answer:
Because it is a recessive disorder both the representative letters will be lowercase. It will look like this, using D as an example: dd

Which evidence is provided by fossil record
The fossil record
This supports Darwin's theory of evolution, which states that simple life forms gradually evolved into more complex ones. Evidence for early forms of life comes from fossils. By studying fossils, scientists can learn how much (or how little) organisms have changed as life developed on Earth.There are gaps in the fossil record because many early forms of life were soft-bodied, which means that they have left few traces behind. What traces there were may have been destroyed by geological activity. This is why scientists cannot be certain about how life began.
Fossils provide a snap shot of the past and allow us to study how much or how little organisms have changed as life developed on Earth.

Why is diffusion such an efficient process
for all cells?
A. It does not require energy.
B. It occurs so quickly.
C. The high amount of energy used during diffusion is offset by
the amount it creates.
Answer:
A.
Explanation:
Diffusion does not require energy. It's depends on the concentration gradient of the two molecules.
Diffusion is such an efficient process for all cells because it does not require energy. Thus, the correct option is A.
What is Diffusion?Diffusion may be defined as the migration of substances from a region of higher concentration to a region of lower concentration through a semi-permeable membrane.
Diffusion does not require any type of energy for the movement of ions, molecules, or substances. It is a very feasible form of migration of substances.
Diffusion is a type of passive transport and hence takes place in a dropping manner without any expenditure of energy.
Therefore, Diffusion is such an efficient process for all cells because it does not require energy. Thus, the correct option is A.

Why is the parietal lobe sometimes called the
"association lobe"?
Answer:
The parietal lobes are primarily responsible for receiving and processing sensory input such as touch, pressure, heat, cold, and pain. The parietal lobes are also involved in the perception of body awareness and the construction of a spatial coordinate system (mental map) to represent the world around us
Answer:
The parietal lobe is one of the four major lobes of the cerebral cortex in the brain of mammals. The parietal lobe is positioned above the temporal lobe and behind the frontal lobe and central sulcus. ... The name comes from the parietal bone, which is named from the Latin paries-, meaning "wall".

how are monosaccharides made from a disaccharide ?? And what’s the reaction called ?
Glucose, galactose, and fructose are monosaccharide isomers, which means they all have the same chemical formula but differ structurally and chemically. Disaccharides form when two monosaccharides undergo a dehydration reaction (a condensation reaction); they are held together by a covalent bond. (Lumen Learning to learn more, or to cite)

Answer:
- The building blocks of DNA molecules are amino acids. False
- DNA molecules contain a 5-carbon sugar called deoxyribose. True
- The nitrogen bases found in DNA molecules include adenine, cytosine, guanine, and thymine. True
Explanation:
The building blocks of the deoxyribonucleic acid (DNA) are nucleotides, while amino acids are the building blocks of proteins. Each nucleotide consists of one of four possible nitrogenous bases: two purines (i.e., adenine and guanine) and two pyrimidines (i.e., cytosine and thymine). In DNA, each nucleotide consists of one of these four nitrogenous bases, a five-carbon sugar molecule (called deoxyribose), and a phosphate group. The DNA molecule has a double-helix structure, where nitrogenous bases are inside the double helix while sugars and phosphates are outside. In DNA, cytosine always pairs with guanine and thymine always pairs with adenine.
