Thomas Malthus was an economist who influenced Darwin's developing theory of evolution. Malthus observed that the birthrate among humans exceeded the death rate. If this trend continued, soon there would not be enough resources to support human population growth. He reasoned that the only things capable of stopping human population growth were famine, disease, and war. Darwin applied this thinking to animals and plants as well, noting that far more offspring were produced than survived to a reproductive age. 2. How did Charles Darwin build on the work of Thomas Malthus to develop the idea of evolution by natural selection

Answers

Answer:

The work of Thomas Malthus help and influence Darwin Thomas to refine his theory of natural selection by explaining that there is a meaningful competition between the individuals of a particular species or population for a specific resource such as food or shelter.

Thomas Malthus predicted that the human population is reproducing faster than its death race and will lead to growing faster than space and food supplies needed to sustain it. Darwin concluded further that If all offspring of almost any species survived for several generations, they would overrun the world and therefore a healthy and meaningful competition is present and to overcome this natural selection takes place as the individual adapt will ultimately survive.

compare the effect of human activity and natural processes on watersheds

Answers

Answer:

What effect do human activities have on natural resources?

Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.

this is somewhat similar

Some human activities that affect watersheds is Building dams and rerouting rivers are two examples of ways humans directly impact water in watersheds. Humans also use water as a resource, drawing from watersheds for our drinking water. This does not have to be a negative impact, as water usage can be monitored so that it is sustainable. Then on the other hand the natural factors the affect the health of a watershed is the quality and quantity of water in streams, rivers or lakes are dependent on its watershed. Another thing is The physical characteristics of a watershed, including geology, soil types, vegetation, topography and slope, also influence water- shed water quality. creek, stream or river to determine aquatic health.

Biology

Answers

Answer:

quantitative data

"quantitative" refers to the amount of something, so if it has something to do with numbers, It's quantitative.

There were twelve elephants in the clearing, which is quantitative data, while the pulse rate of 141 beats per minute is also quantitative data, but the orange fur with black stripes is qualitative data.

What quantitative and qualitative data are there?

There are both types of data, such as the quantitative data, in which the quantity can be measured, such as the 12 elephants and the 141 beats, and the qualitative data, which can't be measured but is widely seen in the genetics, such as the coat color of the animals, the skin color of the human, etc.

Hence, there were twelve elephants in the clearing, which is quantitative data, while the pulse rate of 141 beats per minute is also quantitative data, but the orange fur with black stripes is qualitative data.

a student wants to hold the sides of a garbage bag to the sides of her trash can she tries round rectangular and square shaped magnets but the magnets do not stick to the sides of the trash can, what is a reason the magnets do not stick to the sides of the trash can ?

Answers

Answer:

If the insulating material covered around the can.

Explanation:

If the can is covered with thick layer of insulating material then it can't be attracted by the magnet because there is a gap between magnet and metal. Can is a metal which is attracted by the magnets just like iron and copper etc. If there is no insulating material between magnet and can, then it must be attracted by the magnet so that's why we can say that insulating material is responsible for the no attachment of magnet to the can.

B
What is the frequency of the wave?

C
What is the wavelength of the wave?

D
What is the wave speed in a vacuum?

Answers

Answer:

It would be B

Explanation:

I am sorry if it is wrong

"What is the frequency of wave?" is not a question that she can ask. Thus, the correct option is B.

What is the frequency of wave?

Wave frequency is the number of waves which pass through a fixed point in a given amount of time. The SI unit for wave frequency is the hertz (Hz). One hertz (Hz) equals 1 wave passing a fixed point in the time period of 1 second. A higher-frequency wave has more energy than a lower-frequency wave with the same magnitude of amplitude.

The equation used for determination of wave frequency (f) will be:

f = v/λ

where λ is the wavelength in meters and v is the speed of the wave in m/s.

Therefore, the correct option is B.

Contrast the contraction of the a disease by the environmental, heredity/genetic and pathogenic pathways.

Answers

Answer:

Explanation:

Contraction of a disease by the environment, the environment is said to influence something certain traits either by amplifying them or prevent them from being expressed. Some disease tends to strive in environment that is favorable while some disease don't find expression where the environment is not conducive even though they are presents in the gene of the individual. Environment could include family, area where the individual lives, food, peer

While Contraction of disease that are heredity/genetic and having pathogenic pathways is high this is because any disease that is hereditary can be passed to successive generation through the inheritance of such gene from the parents this increase the likelihood of reoccurrence of such disease in a family where the parents has it.

As carbon moves throughout earths systems how are different parts of the biosphere(the part occupied by living things) affected?

Answers

Answer:

Carbon is an essential factor to the survival of living things.

Explanation:

It is produced as a waste by-product of metabolism in living organisms and combines with oxygen to be released as Carbon Dioxide (CO2).

Plants on the other hand require CO2 to process sunlight and nutrients into energy. They in return release oxygen which is required by animals to break down food.

Factories, businesses, people (as they generate electricity, transport people and goods, etc) release lots of carbon into the atmosphere it also combines with oxygen again to form C02.

The ocean and water bodies also serve as a collecting conduit of CO2, especially where the water temperature is relatively warm. When CO2 is captured by the ocean, it is used by some sea animals to make shells.

16. The substances that are reabsorbed did not diffuse (move) from the nephron bowl into the
renal vein cup. You needed to use lots of energy to make reabsorption happen. Which
process do you think the kidney uses to transport these substances from the nephron to the
renal vein-active transport or diffusion (passive transport)? Explain your answer.

Answers

Answer:

Active transport.

Explanation:

The kidney uses active transport  to move these substances from the nephron to the  renal vein because these substances did not moves from the nephron bowl to the renal vein through simple diffusion so for this purpose active transport is used in which energy is spent in order to move the substances from one region to another so we can say that kidney must use active transport to move reabsorbed substances from the nephron to the  renal vein.

Each band represents a different sized subunit of a multimeric protein. c. Each band represents a protein subunit with different charge to mass ratio. d. These bands represent two subunits of a heterodimer. e. These bands represent two separate subunits of identical size.

Answers

Answer:

b. Each band represents a different-sized subunit of a multimeric protein.

Explanation:

SDS-PAGE analysis allows the separation and discrimination of proteins according to their molecular weight. The technique separates proteins in an electromagnetic field.

The SDS-PAGE technique makes proteins move in solid support -gel- by the action of the electric field. The distance reached by each protein is proportional to their molecular weight. The protein separation from a mixture results in bands that reflect their size.

SDS is a detergent that denaturalizes the protein and sets a relation charge size, such as that the motion of the protein in the gel is proportional to its weight. The bigger the protein is, the stronger interaction with the polyacrylamide gel there will be.  The speed of displacement in the electromagnetic field is inversely proportional to the protein size.
