Maria walks up hill to go to school every day. When she reaches the top of the hill, she is always breathing much faster than when she started. How might this affect how her heart is working? Support your hypothesis with evidence.

Answers

Answer 1

Answer:

''By doing hard activity, the pumps very fast.''

Explanation:

''By doing hard activity, the heart pumps very fast.'' is my hypothesis. In this hypothesis, I mentioned that during hard activity pumping of heart goes very fast because our body needs oxygen as well as energy in the form of ATP and the only way to get both oxygen and energy is the pumping of heart which supply oxygen to the cell as a result energy is generated in the form of ATP and removes carbondioxide gas by breathing.

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.

Explanation:

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 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.

The resting membrane potential of a neuron is generated by Group of answer choices the selectivity of the membrane to pass positive charges only. the greater mobility of small ions. diffusion of ions as a result of their concentration gradients. All of them repulsion of positive and negative charges.

Answers

Answer: diffusion of ions as a result of their concentration gradients.

Explanation:

Resting membrane potential can be defined as the basic charge of the cell. It is defined by the concentration difference between the ions due to the action of the ion pumps. The differential permeability of the membrane is because of the charge on the ions and leads to the creation of the ion channels. The negative charged ions accumulate on the inner side of the cell.

Identify the phases in the life cycle of small and big stars. supernova: In this stage, the star collapses and produces elements heavier than iron. planetary nebula: In this stage, the star emits strong energy pulses that push away the outer layers creating a cloud of ionized gas around the core. neutron star: In this stage, the star has reduced to an extremely dense core. white dwarf: In this stage, the star has reduced to a dense core.

Answers

Explanation:

Some Astronomers believe the life cycle of small stars begins in this order:

Planetary nebula phase: this phase is the result of the previous red giant phase (when the star turns red in color). However, at this stage, the star keeps expanding, glowing, and getting hotter as it strives to complete its life--cycle.White dwarf phase: As the name implies, the star now has a reduced size and a dense core than during the Nebula phase, while still glowing with surface temperatures of over 100,000°C.Neutron star: This stage occurs next after the White dwarf phase which may result in the final death of the star. Here the star is reduced to an extremely dense core.

While the life cycle of big stars begins in the order:

Supernova phase: At this phase, the star collapses and produces other heavier elements.Neutron star phase or may formBlack Holes.

D. They define geological periods because scientists use them as reference points for  tracking the history of the earth.

Explanation:

Catastrophic events related to changes in geological timeline are very useful in defining geological periods.

These events have very significant appearance in the geological record and can be used to determine the history of the earth.

The catastrophic events usually culminates into extinction cycles or termination of some organisms from the earth surface.

Geologists use these events that are often wide spread to delineate geological periods.

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

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.
