i) Predict which of the liquids would cause the largest decrease in mass of a potato stick
PLS HELP ME I’ll GIVE YOU 15 POINTS OR BRAINIEST
Answers
Answer:
1.0 mole per dm3 sodium chloride solution
Explanation:
The more the molarity of a solution, the lower the water potential of the solution, and the higher the amount of water that will osmotically move from the potato stick to the solution when placed in it in order for an equilibrium to be established.
Hence, the 1.0 mole per dm3 sodium chloride solution will cause the largest decrease in the mass of the potato stick when compared to the 0.5 and 0.1 mole per dm3 sodium chloride solutions.

Which of these organisms would most likely be found at the top of an energy pyramid?
A. clams - a primary consumer
B. sardines - a primary consumer
C. sharks - a secondary consumer
D. kelp - a primary producer
Answers
Answer:
sharks
Explanation:
Because they are the ones to get the last bit of energy. Secondary consumers are the group in the food chain that eats primary consumers. This means that secondary consumers can either be omnivores or carnivores. These terms refer to whether or not they eat just meat or a varied diet. Secondary consumers don't need to have a specific diet.
The energy pyramid is a representation of the producers and consumers along with the flow of energy. The sharks will be at the top of the energy pyramid. Thus, option C is correct.
What is an energy pyramid?An energy pyramid is a graphical representation of the biomass of the producers and the consumers of the ecosystem. It consists of the trophic levels that have designated producers, primary consumers, and secondary consumers.
A producer is at the bottom of any energy pyramid as they produce the foods for the primary consumers that are most likely herbivores. The secondary or the tertiary consumers are at the top.
Therefore, option C. sharks being secondary consumers are at the top of the pyramid.

By genetic modification and evolutionary processes, biodiversity is increased and decreased by habitat loss, population reduction and extinction. The number and relative abundance of species present in a given biological organization is simply species diversity (population, ecosystem, Earth).
Answers
Answer:
Genetic Modification is a procedure to change the qualities of a plant, creature or miniature life form by moving a bit of DNA from one living being to an alternate living being. This is done through focused expulsion of the ideal qualities from the DNA of one living being and adding them to the next living being. This strategy has for instance been utilized to create growths and microorganisms that produce drugs.
Evolution is the cycle by which current creatures have dropped from old progenitors. Evolution is liable for both the surprising similitude we see over all life and the astonishing variety of that life.
Explanation:
Evolution is change in the heritable qualities of organic populaces over progressive ages. These attributes are the statements of qualities that are given from parent to posterity during generation. Various attributes will in general exist inside some random populace because of transformation, hereditary recombination and different wellsprings of hereditary variety. Evolution happens when transformative cycles, for example, regular choice (counting sexual choice) and hereditary float follow up on this variety, bringing about specific qualities getting more normal or uncommon inside a populace.
It is this cycle of development that has offered ascend to biodiversity at each degree of natural association, including the degrees of species, singular life forms and atoms.
Draw a neat labelled structure of heart and write about valves in heart
Answers
Answer:the valves prevents the backward flow of blood
Explanation:
Answer:
The labelled structure of the heart is attached below. The valves in the heart prevent the backward flow of blood. These valves are actual flaps that are located on each end of the two ventricles (lower chambers of the heart). They act as one-way inlets of blood on one side of a ventricle and one-way outlets of blood on the other side of a ventricle.

1. Animals can face many problems caused by light pollution. Which is NOT one of these
problems?
a. Increased predation
b. Decreased amount of food
c. Disorientation
d. Disrupted breeding times
Answers
Answer:
Light pollution does not affect predation levels, so the correct answer is A
Explanation:
Increase predation is one of them which is not affected by Light pollution.
What is light pollution?Artificial illumination that is undesirable, improper, or excessive is referred to as light pollution.Light pollution, also known as artificial light at night, is the excessive or inefficient use of artificial outdoor light that disturbs wildlife's normal routines, adds to the buildup of carbon dioxide (CO2) in the atmosphere, interrupts human sleep, and obscures the night sky's stars.What is predation?One creature kills and eats another in predation. Predation offers energy to the creature that kills, the predator, in order to prolong its life and encourage reproduction at the expense of the organism that is eaten, the prey. Predation has an ecological impact on species on two levels.Hence, the correct option is A.

If you were to test a small
sample of soda lime with
universal indicator would it
register a pH above or
below 7? Explain your answer
Answers
The soda contains CO2 that is dissolved CO2 reacts with water
CO2+H2O--->H2CO3
to form carbonic acid
this is a weak acid but it gives protons to water
H2CO3+H2O-->-HCO3+H30+
pH=-lg[H3O+]
[H3O+] is the molar concentration
Therefore the acid present in the solution causes the pH to be lower than 7. It can either be the H2CO3 if it is a carbonated beverage or citric acid from lime juice.

Which is a least likely function of lipids in plants and animals?
A.to transfer hereditary information
B.to supply energy
C. to provide insulation and protection
D. to make up cell membranes
Answers
Answer:
A. ) To transfer hereditary information
Explanation:
The least likely function of lipids in plants and animals is to transfer hereditary information. Thus, the correct option for this question is A.
What are Lipids?Lipids may be defined as a type of chemically diverse group of organic compounds that are insoluble in water but are readily soluble in non-polar solvents like benzene, chloroform, ether, etc.
The classical functions of biological lipids include the following:
Serve as a storage form of metabolic fuel.They provide structural components of cell membranes.They also deliver the property of insulation and protection of cells.Lipids are also utilized in order to supply energy to the cells.The biomolecules or compounds that significantly deal with the function of transferring biological and hereditary information are known as proteins.
Therefore, transferring hereditary information is one of the least likely functions of lipids in plants and animals. Thus, the correct option for this question is A.

how could changing one mRNA codon change a protein?
Answers
Answer:
the outcome of a frame shift mutation is complete alteration of the amino acid sequence of a protein. This alteration occurs during translation because ribosomes read the mRNA strand in terms of condons,or groups of three nucleotides. theses groups are called the reading frame.
Explanation:
hope that helps.:)
Changing one mRNA codon will change a protein because each protein
have their specific mRNA codons.
The mRNA codon are translated into a single amino acid during polypeptide
formation. Changing one mRNA codon will result in the formation of a
different type of protein.
The mRNA codon comprises of three base pairs and a change in an amino
acid such as Alanine which has a codon of GCA which when replaced by
GAC will form aspartic acid.
