Photosynthesis and cellular respiration are both complementary and relatively balanced on modern Earth, but early history of life on Earth showed increasing oxygen concentrations 2.5-2 billion years ago. This indicates that

Answers

Answer 1

Answer: d. the amount of photosynthesis occurring exceeded the amount of cellular respiration.

Explanation:

In the process of photosynthesis, oxygen is produced from carbon dioxide as plants make their own food. In cellular respiration, carbon dioxide is formed as oxygen is used to covert sugar into energy.

Photosynthesis produces oxygen and respiration produces carbon dioxide. If oxygen concentrations are increasing therefore, it means that more oxygen is being produced than being used which means that the amount of photosynthesis occurring must be higher than respiration because it is producing more oxygen than respiration can use.

Answers

Answer:

Due to difference in angle.

Explanation:

Irregularities in the temperature cycle are caused by the difference in angle of the sun. The angle of the sun is directly related to the intensity of the solar radiation. If the angle of the sun is at 90 degree so the intensity of the solar radiation is at maximum which leads to high temperature while on the other hand, at the sunset and at the sun rise the angle is lower than 90 degree which leads to lower intensity of the sun and also lower in temperature.

region

Answers

Answer:

1. Oceanographer

2. Geologist

3. Astronomer

4. Environmental scientist

5. Meteorologist

Explanation:

1. Oceanographer: studying waves, currents, and tides. He or she is an individual that studies the science of ocean with respect to waves, currents, and tides.

2. Geologist: collecting rock samples from the site of a volcano. A geologic column can be defined as a collection of rock layers that are typically grouped based on their relative ages in a descending order i.e from oldest to the youngest.

3. Astronomer: studying the life cycle of a star. A star is a giant astronomical or celestial object that is comprised of a luminous sphere of plasma, binded together by its own gravitational force. It is typically made up of two (2) main hot gas, Hydrogen (H) and Helium (He).

4. Environmental scientist: testing water samples to analyze effects of pollution. Pollution can be defined as the physical degradation or contamination of the environment through an emission of harmful, poisonous and toxic chemical substances.

5. Meteorologist: predicting weather patterns in a particular region. Weather can be defined as the atmospheric conditions of a particular area over a short period of time. The elements of weather include precipitation, wind, temperature, atmospheric pressure, relative humidity, cloud, and wind speed.

Answers

Answer:

Due to volcanic eruptions.

Explanation:

The rocks older than 11 million years no longer exist on the seafloor east of the ridge because of the eruption that occurs on the seafloor which melted the 11 million years rocks. There is enormous volcanic eruption occurs from the ridge present on the seafloor which melted the rocks that are present on the seafloor so that's why we can say that the volcanic eruptions remove all the rocks of 11 years of age.

Answers

Answer:

The correct answer is - d) divides Earth between equal halves of lightness and darkness.

Explanation:

The circle of illumination bisects the equator and it is an imaginary line that separates equal halves of lightness and darkness. It cuts all the latitudes into half spring and autumnal equinoxes. It distinguishes the day area or hemisphere on earth from the night hemisphere.

Earth separates into the Eastern Hemisphere and the Western Hemisphere by the prime meridian line whereas the line of zero degrees or the equator line divides Earth between northern and southern hemispheres.

describe the processes that are responsible for condensation to take place close to the ground​

Answers

Mark Brainliest please

When condensation occurs closer to the
Earth's surface we can see fog, dew or Frost.

1. Fog:- As the temperature of the layers off the air the surface of the earth reduces water vapour condenses it turns into very small water particles and float in the air when the density of the droplets in the air increases fog occurs

2. Dew:- When moisture Laden air near the earth surface comes in contact with very cold objects condensation of vapour takes place and it turns into very small water droplets these water droplets. These water droplets stick to the surface of the cold objects and form dew.

3. Frost:- If the temperature of the air riches below 0 degree Celsius the Dew freezes. this frozen water droplet is called Frost

a. Sediment becomes spread out fairly evenly
b. More sediment becomes available downshore
c. More sediment is deposited on the side of the longshore current
d. Less sediment is deposited on the side of the longshore current

Answers

Answer:

The answer is "Option d".

Explanation:

The cities upon the seaside often construct grounds that stretch inside the water to preserve their beach. It procedures is done out through sand on the side of the coast, which leads to deposit AND the sediment in the region underneath the coastline are much less accessible, which causes the coastal beach to start to erode.

Develop three good questions about microminerals or any of the other information on minerals.

Answers

Answer and Explanation:

Hi. Here are the three questions, with answers, about microminerals.

What is the main difference between micro and macrominerals? The main differences are in the necessary amount that each of these elements need to be presented to an organism. Microminerals are needed in amounts less than 100mg per way, while macrominerals are needed in amounts greater than that.

What are microminerals? Cobalt, copper, iodine, iron, manganese, selenium, zinc, molybdenum, cadmium, fluorine, silicon, chromium, vanadium, nickel, arsenic and tin.

What are microminerals for? Each micromineral has its specific function, but if we have to mention a general function of all of them, it would be the capacity to serve as a basis for the construction of materials and molecules needed in everyday life, as if they were the building blocks of an important construction.
