What does the Greek Root "pro" mean?

Which of the following is a possible path for carbon to cycle through an ecosystem?

1. Atmospheric CO2 -> animals -> factories -> fossil fuels -> plants

2. Atmospheric CO2 -> factories -> fossil fuels -> animals -> plants

3. Atmospheric CO2 -> plants -> animals -> fossil fuels -> factories

4. Atmospheric CO2 -> fossil fuels -> factories -> animals -> plants

Answers

Answer: 3. Atmospheric CO2 -> plants -> animals -> fossil fuels -> factories

Explanation:

The carbon cycle is one of the types of biochemical cycles in which carbon is recycled in atmosphere, biosphere, lithosphere, and hydrosphere in various forms. The atmospheric carbon dioxide is absorbed by the plants and they utilize it as reactant for the process of photosynthesis in which they synthesize their own food. These plants are consumed by animals further when these plants and animals die their remains form fossil fuels deep beneath the earth crust. It takes about millions of years for fossil fuels to form in the sedimentary rocks. The fossil fuels are utilized by the factories to run their machines. Again when fossil fuels burn they emit carbon dioxide gas in the atmosphere.

Landforms are created through destructive forces such as weathering. Which of these is an example of physical weathering? A acid rain. B abrasion. C hydrolysis. D oxidation

Answers

Answer:  C. HYDROLYSIS

Explenation: Chemical weathering occurs when water dissolves minerals in a rock, producing new compounds. This reaction is called hydrolysis. Hydrolysis occurs, for example, when water comes in contact with granite.

Landforms are created through destructive forces such as weathering, so abrasion is an example of physical weathering that is in Option B as the physical weathering is a type of weathering that involves mechanical breakdown.

What is the significance of weathering in the environment?

Physical weathering is caused by physical forces, such as the expansion and contraction of rock due to changes in temperature and abrasion is a specific type of physical weathering that occurs when rock or soil is rubbed against other rock or soil. In physical weathering, rock fragments or particles are carried by water, wind, or ice, and the repeated collisions and friction caused by abrasion can lead to significant changes in the shape.

Hence, landforms are created through destructive forces such as weathering, so abrasion is an example of physical weathering that is in Option B as the physical weathering is a type of weathering that involves mechanical breakdown.

Heredity is the passage of what from parent to offspring?

a. Genetic material
b. Oxygenated blood
c. Digestive enzymes
d. Connective tissue

Answers

Answer:

A

Explanation:

Genetic material is what passes down traits and makes us look similar to our parents

When we talk about heredity, we're talking about the precise ways that genes are used to transmit traits or characteristics from one generation to the next, hence option A is correct.

What is Heredity?

The instructions for creating certain proteins, which are in charge of an individual's distinctive qualities, are encoded by genes.

The youthful creation of living creatures, known in biology as progeny, can be created by a single organism or, in the event of sexual reproduction, by two organisms.

DNA (deoxyribonucleic acid), which makes up genes, contains instructions for how cells should function as well as the traits that distinguish each individual.

Therefore, each of your biological parents contributes half of your DNA to you, and you could inherit a gene mutation from one or both of them, hence option A is correct.

A population of African lions share the same habitat. A small group becomes reproductively isolated
from the rest of the population (mating behaviors no longer match). What type of speciation is this?
a. Allopatric speciation
b. Sympatric speciation
C. Parapatric speciation
d. Peripatric speciation

Answers

Answer:

The correct answer is - B. sympatric speciation.

Explanation:

The allopatric speciation occurs in the population that is geographically isolated, parapatric speciation takes place due to reproductive isolation however they occupy distinct nice or habitat.

Peripatric speciation is shows resemblance to allopatric speciation in terms of preventing the exchange of genes however they occur in the small peripheral population.

Sympatric produces a reproductive barrier between the small population that shows change to the parent population.

Which idea associated with relative dating helped inspire Charles Darwin's work on evolution?

Answers

Answer: The idea that the earth is extremely ancient.

Explanation:

Charles Darwin was a British naturalist who worked on the organic evolution of living organisms and in his books outlined how present-day organisms evolved from earlier, different species.

Evolution is an extremely slow process. It is difficult to obtain direct evidence of evolution in action. However, scientist including Charles Darwin, have from many fields gathered a great deal of indirect evidence that supports the theory of evolution. This evidence comes from many sources which include the FOSSIL RECORDS.

The history of life on earth is recorded in fossils (remains of organisms preserved mainly in earth's sedimentary rocks). Scientist can determine the age of rocks in which fossils occurs by using RELATIVE DATING. This method give a geological time scale, showing earth's age ( as measured by dating it's rocks), and tracing the history of life on it.

Therefore the idea that the earth is extremely ancient is associated with relative dating which has helped inspire Charles Darwin's work as an evidence on evolution.

The following passage explains the relationship between tectonic plates and earthquakes. Which sentence states incorrect information?


Tectonic plates can push together, pull apart, or slide past each other at their boundaries. The edges of tectonic plates are not smooth, so they create friction as they move. When friction is too great for the plates to move, they can become stuck and pressure can build up. An earthquake occurs when pressure that has built up between plates suddenly is released. The buildup of pressure that leads to earthquakes only occurs at plate boundaries.​

Michael planted a tomato plant that produces very juicy tomatoes. When the

salad with the tomato at lunch. Later that afternoon, he ran 2 miles during PE and was
sweating at the finish line. How many total energy transformations does this scenario
demonstrate?
1 (potential to kinetic)
2 (chemical to potential,
potential to thermal)
3 (solar to chemical, chemical
to kinetic, kinetic to thermal)
4(chemical to potential
potential to kinetic, kinetic to
nuclear, nuclear to thermal)

Answers

Answer:

3 (solar to chemical, chemical to kinetic, kinetic to thermal)

Explanation:

Michael ate a salad. The salad which he consumes becomes chemical energy, but the tomato he put in his salad has used solar energy, which is simply energy from the sun. The kinetic energy is when he runs 2 miles as kinetic energy is the energy gained from movement. When he stops running, he sweats, which means he is losing heat from his body, therefore the kinetic energy store transfers to the thermal (internal) energy store.
