The correct answer is as follows.
This is because my parents were heterozygous for the color of the beans. The color of the plant beans is the case of simple Mendelian laws, as there are only two choices for the color of the beans.
What is the meaning of Mendel's laws?Mendel's laws refer to a specific pattern of how a trait is passed from parent to offspring. These common patterns were established by the Austrian monk Gregor Mendel, who conducted thousands of experiments on bean plants in the 19th century.
What is an example of a heterozygous?If the two versions are different, the genotype of the gene is heterozygous. For example, a heterozygous hair color means that there is one red hair allele and one brown hair allele. The relationship between the two alleles affects which trait is expressed.

Hich one of the substances is not transported by the human circulatory system?(1 point) a) water b) digested food c) carbon dioxide d) undigested food 5
Answer:
D
Explanation:
Undigested food is not transported by the human circulatory system. Hence, option D is correct.
What is the circulatory system?The system which contains the heart, blood vessels, and blood is called the circulatory system. There are three types of circulation that take place in the body and that is systemic, coronary, and pulmonary circulation.
The heart is a muscular organ, that pumps blood in the body. Blood vessels carry blood from the heart to tissues or tissues to the heart. Blood is a fluid, which flows inside the blood vessels.
The main function of this system is to transport water, nutrients, digested food, oxygen, carbon-di-oxide, minerals, and excretory products in the entire body through blood. It does not transport undigested food. Hence, option D is correct.

The pH is a measure of the concentration of the hydrogen ion (H+) in water. Highly acidic water has a very high H+ concentration, while basic water has very low H+ concentrations. The pH scale is a logarithmic scale, such that a difference of one pH unit means a 10-fold difference in H+ concentration. The mathematical relationship between pH and H+ concentration ([H+]) is
pH = –log [H+] OR [H+] = 10-pH where [H+] is in moles per liter.
Use a scientific calculator to calculate [H+] for the following pH values:
7 (a neutral solution)
5.6 (unpolluted rainwater)
3.7 (first acid rain sample in North America)
How many times higher is the concentration of H+ in the Hubbard Brook sample than in unpolluted rainwater?
The hydrogen ion concentration of the following pH samples is as follows:
7 (a neutral solution) = 0.8455.6 (unpolluted rainwater) = 0.7483.7 (first acid rain sample in North America) = 0.568How to calculate hydrogen ion concentration (H+)?The pH is a measure of the concentration of the hydrogen ion (H+) in water. This means that a relationship exists between H+ and pH of a solution.
The mathematical relationship between pH and H+ concentration ([H+]) is as follows:
pH = –log [H+]
This means that the hydrogen ion concentration (H+) of the following pH values can be calculated thus:

While doing the Osmosis, Effect of Solute Concentration experiment, forgetful Frank left his bag with 10% sucrose in the beaker of water for 2 hours instead of one, how would his results be different from the rest of the class?
The effect is that Frank's 10% sucrose bag will be heavier than that of others.
OsmosisWater molecules move from the region of lower solute concentration to the region of higher solute concentration.
Thus, water will continue to enter into a 10% sucrose bad dropped in a beaker of water until an equilibrium is established between the 2 media.
This means that the longer the bag stays in the beater containing water, the more the water will enter, and the heavier it will weigh.

VALUE BASED QUESTION (Write in about 50-100 words)
Consider the following two cases: (Please give answer ASAP)
(i) A forest that is rich in biodiversity sees a decline in the animal population and clearing of a large
part of the forest. The Government declared it as a biodiversity hotspot and the forest regained its
species richness in few years.
(ii) A lake that is rich in marine fishes sees a decline in its species population due to over harvesting.
The people living in the area made the lake a sacred grove and started worshipping it. The species
population of the lake again became normal.
Answer the following questions based on the above information:
(i) Which values are being promoted in the above cases?
Case 1:-
Case 2:-
(ii) Suggest some ways in which you can contribute to this concern.
Case 1:-
Case 2:-
(iii) What would have been the effect if the forest was not declared a biodiversity
hotspot?
The value that can be withdrawn from case 1 is the activeness of the government that takes some crucial steps to maintain the biodiversity of the forests. The value that can be withdrawn from case 2 is the sincerity of native people towards nature who make a lake a sacred grove and start worshipping it in order to maintain the biodiversity of that lake.
What is Biodiversity?Biodiversity may be defined as the sum total of all the living entities living in a particular area at a given time.
For maintaining the biodiversity of the forest as well as a lake, it is required not to deteriorate the natural ecosystem of those regions by human activities like over grazing, forest fires, over harvesting, industrialization, etc.
If the forest has not been declared a biodiversity hotspot, the time will not be far to announce that a forest becomes a bare area, where no species live, survive, and reproduce naturally.

Some people have their gall bladder surgically removed to the formation of gall stones. Describe the function of the gall bladder and explain how a gall bladder removal would have on their digestion.
Underneath the right side of the liver, the gallbladder is a pear-shaped organ.
What is the function of gall bladder?Its primary function is to gather and concentrate bile, a digestive fluid made by the liver. The gallbladder is where bile is kept after the liver produces it. The gallbladder receives a signal from the stomach when you eat. Bile is released from the gallbladder when it contracts, and it travels through the gut via the major common duct. Bile combines with the food there and aids in digestion.
When the gallbladder is removed from a healthy person, there are rarely any obvious health or digestive issues, though there is a slight chance of diarrhea and fat malabsorption.
