What are biomolecules?Biomolecules are also called biological molecules. These are the numerous substances produced by the cells of our body and all other living organisms.
These molecules vary widely in range in their size and structure. They are also able to perform a wide range of functions. Carbohydrates, lipids, nucleic acids, and proteins are the four major types of biomolecules.
Nucleic acids form our genetic material. DNA or RNA present in our cells are formed from nucleic acids.
Proteins are a wide range of structural and functional molecules. Proteins form the structures of the cell membrane. They also form enzymes.
Carbohydrates and lipids are major sources of energy in our food. They also have various structures.

Below are the seven properties of water that make life possible on Earth. Describe five of these properties and provide an example of each:
Hydrogen bonding, cohesion and adhesion, surface tension, heat of vaporization, specific heat, density, and universal solvent
Answers
Answer:
Water in its liquid form has a boiling point temperature close to 100°C. As a result of the network of hydrogen bonding present between water molecules, a high input of energy is required to transform one gram of liquid water into water vapor, an energy requirement called the heat of vaporization.
Cohesion is responsible for the transport of the water column in plants. Adhesion is water attracted to other material.
Water has a greater surface tension than most other liquids because hydrogen bonds among surface water molecules resist stretching or breaking the surface.
Specific Heat is the amount of heat that must be absorbed or lost for one gram of a substance to change its temperature by 1*C.
Density is when hydrogen bonds in water expand as it warms and contracts as it cools. The hydrogen bonds keeps the molecules far enough a part to make ice have fewer molecules.

They might be single-celled and extremely sensitive to change, but regardless of this, they play a crucial role in the food chain and in maintaining the health of our planet.
What characteristics that the life to possess?Cellular organization, the capacity for sexual reproduction, growth and development, energy usage, homeostasis, reaction to their environment, and the capacity for adaptation are characteristics shared by all living creatures.
All of these characteristics will appear in living creatures. Despite changes in the external environment, living things strive to maintain a constant internal temperature.
Homeostasis is a process like this, and it ranks as the sixth most significant aspect of life biology.
Excretion, growth, sensibility, movement, breathing, and reproduction. While some non-living creatures might exhibit one or two of these traits, only living organisms exhibit all seven traits.
Therefore, reproduction, growth, and development are the characteristics that the life to possess.

why do scientist use a common system of measurement
Answers
To keep the accuracy, consistency and minimize the discrepancy in the experimentation, a common system of measurement was favoured by the scientists.
What is a system of measurement?A system of measurement is formed of standardized units that are used to define a quantity.
System of measurement is referred as SI unit. It is considered the same universally. System of measurement is accepted everywhere with the same units of measurement.
It is used for the measurement of length, time, mass, temperature, current etc.
System of measurement is advantageous as it eliminates the confusion regarding different expression of units.
It makes the interpretations and comparisons easier as the conversion of measurement units will be nil.
System of measurement provides a reference units for various experimental analysis. It is important in research and quality analysis.
Thus, system of measurement enables correct interpretations of calculations.

How would pepsin activity be affected if it were put in a neutral solution?
Answers
Answer:
pepsin would either work at extremely slow pace or get denatured.
The activity of pepsin would be inhibited if put in a neutral solution.
Pepsin is one of the enzymes found in the gastric juice of the stomach. It is a protease that digests protein into polypeptides , which are intermediate products of protein digestion.
A neutral solution is a solution that contains hydrogen ions and hydroxide ions at equal concentration.
But Pepsin works best in an acidic medium which is provided by the hydrochloric acid secreted in the stomach.
Therefore when pepsin is put in a neutral solution, the activities would be inhibited.

How can the founder effect cause a previously rare genetic disorder to become common in the new population?
Answers
Answer and Explanation:
The founder effect is a special case of genetic drift.
The Founder effect refers to the consequences that occur from the origin of a new population produced by a small number of founder individuals that come from an ancestral bigger population. The new population originated from a few founder individuals, who came from a bigger population and that established in a new environment.
This small population might or might not be genetically representative of the original one. It might show poor genetic variation and hence, a high possibility of expressing a peculiar allelic composition. Some rare alleles might be in exceed or might be completely lost. Consequently, when the small population increases in size, it will have a genetically different composition from the original one. In these situations, genetic variability is reduced and there is a high possibility of developing a peculiar allelic composition. If the number of individuals that originates the new population is very low, the founder effect will be very extreme, because the magnitude of this change is inversely related to the original number of the founder individuals. These changes produced by genetic drift accumulate in time, and eventually, some alleles get lost, while some other might set.
There are certain examples of the founder effect, such as Huntington's disease in South Africa or the Ellis syndrome characteristic of the Amish people from Pennsylvania.

which statement best describes how an existing theory is often affected by the development of new technology
Answers
Answer:
ringthibf
Explanation:
You are concerned about the rate of death in catfish your aquaculture operation in tanks that have a high amount of algae growth. You collect some of the algae and send it to the university to have it identified. You find that it is a blue-green alga called Anabaena. Anabaena is known to be toxic to fish. You design an experiment to test how much of the algae the fish can stand before they die. You obtain 6 large aquariums (all the same size) and fill them with water taken from a healthy catfish pond at your operation. You put each aquarium on the same bench in the laboratory, where the light and temperature values are identical. You let the water stand for one day before starting the experiment. In aquarium 1, you add 2 grams of algae and no fish. In aquarium 2, you add 20 small catfish and no algae. Aquarium 3 gets 20 catfish and 2 grams of algae, #4 gets 20 catfish and 4 grams of algae, #5 gets 20 catfish and 8 grams of algae, and aquarium #6 gets 20 catfish and 16 grams of algae. The aeration rate of each aquarium is identical. You make two observations at the same time each day for two weeks. You keep track of the numbers of fish in each tank that die.
What is the problem?
What is your hypothesis?
What is the independent variable?
Answers
Answer:
Hypothesis is ''With the increase of algae in the aquarium, fish population decreases''.
Explanation:
The main problem was that there is no need for 2 aquarium because there is no need for aquarium 1 which has no fish and aquarium 2 which has fishes but no algae. With the increase of algae in the aquarium, fish population decreases is the hypothesis for this experiment. Concentration of algae is the independent variable of the experiment because there is no effect on it in the experiment.
