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 difference between gene mutations and chromosomal mutations, including:
- What are they?
- How do they occur, including their types?
- When will they result in a change in the phenotype of offspring?
Explanation:
Genetic alternations include chromosomal abnormalities and gene mutations. Chromosomal abnormalities generally arise during cell division. ... Gene mutations are permanent changes in DNA gene sequence. They can arise during normal DNA replication or in response to environmental factors.
Answer:
When a gene mutation occurs, the nucleotides are in the wrong order which means the coded instructions are wrong and faulty proteins are made or control switches are changed. The body can't function as it should. Mutations can be inherited from one or both parents. They are present in the egg and/ or sperm cells.
What type of mutation can affect offspring?
The only mutations that matter to large-scale evolution are those that can be passed on to offspring. These occur in reproductive cells like eggs and sperm and are called germ line mutations. No change occurs in phenotype. Some mutations don't have any noticeable effect on the phenotype of an organism.

The order of the genes on a plant chromosome is A, B, C, where A and B are located 10 cM apart and B and C are located 3 cM apart. What is the probability that the trihybrid ABC/abc will produce any kind of recombinant gamete
Answer:
Double Crossing-over prob = 0.3% Simple Crossing-Over prob A-B = 9.7%Simple Crossing-Over prob B-C = 2.7%Total Crossing-Over prob = 12.7%Explanation:
Available data:
order of the genes on a plant chromosome is A, B, CA and B are located 10 cM apartB and C are located 3 cM apartThe genetic distance = recombination frequency x 100 expressed in map units (MU). One centiMorgan (cM) equals one map unit (MU).
We can use the provided map with the distances between genes to predict the occurrence of any kind of recombinant gamete.
We know that there is a probability of a simple crossing over to occur between genes A and B, or between genes B and C. And we also know that there is a probability of double crossing-over occurrence.
We can get the probability of the double-crossing over by multiplying the recombination frequencies between A-B and B-C. So,
DCO prob = recombination frequency A-B x recombination frequency B-C
= 0.1 x 0.03 = 0.003 = 0.3%
DCO prob = 0.3%
According to this, we would expect to find
0.15% AbC0.15% aBcNow we need to know what are the probabilities of getting a simple crossing-over, SCO. We already have the genetic distances between genes. 10 cM equals 0.1 of recombination frequency, and 3cM equals 0.03 of recombination frequency. However, we can not estimate the probabilities of simple crossing over using only this information, because this data is including the probabilities of the double crossing-over occurrence. So we need to substrate this percentage.
SCO prob A-B = 0.1 - 0.003 = 0.097 = 9.7%
SCO prob A-B = 9.7%
we would expect to find
4.85% Abc4.85% aBCSCO prob B-C = 0.03 - 0.003 = 0.027 = 2.7%
SCO prob B-C = 2.7%
we would expect to find
1.35% ABc1.35% abCThe total Crossing-over probability, TCO, is then the sum of all the crossing over probabilities,
TCO= SCO A-B + SCO B-C + DCO
TCO prob = 9.7% + 2.7% + 0.3%
TCO = 12.7%

1. What is a biogeochemical cycle?
2. What drives, or powers, the water cycle?
3. What causes water to condense and form clouds?
Answer:
1. In ecology and Earth science, a biogeochemical cycle or substance turnover or cycling of substances is a pathway by which a chemical substance moves through biotic and abiotic compartments of Earth.
2. The sun, which drives the water cycle, heats water in the oceans. Some of it evaporates as vapor into the air. Rising vapor cools and condenses into clouds.
3. Heated by sunshine, the ground heats the air just above it. That warmed air starts to rise because, when warm, it is lighter and less dense than the air around it. As it rises, its pressure and temperature drop causing water vapor to condense. ... The air cools as it rises, and eventually clouds form.
