A simplified carbon cycle is depicted here. The release of carbon dioxide into the atmosphere can contribute to global warming. The statements describe the processes of forest fires, fossil fuel combustion, and plant respiration are they occur under anaerobic conditions primarily, they are all directly caused by human intervention, and they are primarily the result of microbial activity. Thus, option A, B, and C are correct.
What is carbon dating?Carbon dating or radiocarbon dating has been known as the method to identify the age of any substance by using the properties of radiocarbon. The method has been developed in late 1940 at university of Chicago.
Carbon dating has been the process by which we can find the extrapolated data which stored by tree rings can be identified which thousands year old.
Carbon has been known as the one of the chemical elements. Along with hydrogen, nitrogen, oxygen phosphorus and sulfur carbon has a building block of biochemical molecule ranging from fats, proteins and carbohydrates.
Therefore, A simplified carbon cycle is depicted here. The release of carbon dioxide into the atmosphere can contribute to global warming. The statements describe the processes of forest fires, fossil fuel combustion, and plant respiration are they occur under anaerobic conditions primarily, they are all directly caused by human intervention, and they are primarily the result of microbial activity.

8. Many scientists believe that at one point in history, the polar bear was a close relative of the
brown bear and fossil samples show the connection. Over time, the species spread out into
different areas and became two entirely different species. Which is the most likely explanation
for this phenomenon?
A Polar bears were geographically isolated and over time their color has adapted to fit their
surroundings
B Polar bears color was caused by a genetic mutation and in order to survive the bears had to
migrate north
C Brown bears color was caused by a genetic mutation and in order to survive the bears had to
migrate south

What genotypes are observed when you cross a Dd parent
with another Dd parent?
a. 100% DD
b. 75% DD and 25% dd
c. 50% DD and 50% dd
d. 25% DD, 50% Dd, 25% dd
Answer:
it is D. 25%DD ,50%Dd ,25%dd
If both the parents are heterozygous (Dd), the resulting offspring are 25%DD, 50%Dd, and 25%dd. So, the correct option is D.
What do you mean by genotypes?Genotypes may be defined as the ultimate combination of alleles of those genes which are selected for our study.
Here, both the parents carry the genotype Dd, when Dd is crossed with Dd, the resulting offspring are 1DD, 2Dd, and 1dd.
Therefore, if both the parents are heterozygous (Dd), the resulting offspring are 25%DD, 50%Dd, and 25%dd.

stroma
granum
xylem
phloem
Explanation:
As I think Stroma and granum are the correct answer.
There are two distinct regions present inside a chloroplast known as the grana and stroma. Grana are made up of stacks of disc-shaped structures known as thylakoids. The grana of the chloroplast consists of chlorophyll pigments and are the functional units of chloroplasts.

1. How do you get your zenith distance from the altitude of the Sun at solar noon?
2. How do you get your latitude from your zenith distance and the Sun's declination?
Answer: The zenith angle is the angle between the sun and the vertical. The zenith angle is similar to the elevation angle but it is measured from the vertical rather than from the horizontal, thus making the zenith angle = 90° - elevation.
Since it is South of the Zenith, we add the zenith distance to the declination to find our latitude: our latitude = the declination + the zenith distance = -17° + 39° = +22° (North latitude).

Which statement best describes the motion of the plates along these boundaries that causes the earthquakes? The plates push apart from each other with no subduction. Subduction occurs with the less-dense plate sinking below the other plate. Subduction occurs with the more-dense plate sinking below the other plate. The plates smash together with no subduction.
Answer:
D). The plates smash together with no subduction.
Explanation:
As per the question, the last statement most adequately demonstrates the movement of plates i.e. 'the plates hit together without any detraction' through concurring boundaries causing the earthquakes to take place. The continuous smashing of tectonic plates with one another leads to the development of a pressure towards both the rock layers by the time this stress is released through a shaky or convulsive movement of the Earth. Thus, option D is the correct answer.

What was the discovery scientists made in the 1950's that led them to then accept Wegener's theory of Continental Drift?
Answer & explanation:
The theory of continental drift emerged a long time ago. When mapping some points on Earth, scholars suspected that the continents were united in the past.
Francis Bacon suggested in 1620 that the east coast of the South American continent and the west coast of Africa fit together perfectly, giving the impression that they had parted in the remote past. A similar observation to this had already been made by another scholar named Abraham Ortelius, around 1596.
A century later, hypotheses became a scientific theory with previously elaborated arguments. Then, the theory of Continental Drift was officially born, when the German Alfred Wegener formulated it in 1912, establishing that the Earth had been divided, in its slow fragmentation, into two great continents, Laurasia and Gondwana.
What effect does the heating of Earth have on air and water movement?
Answer:
Solar heating of the Earth's surface is uneven because land heats faster than water, and this causes air to warm, expand and rise over land while it cools and sinks over the cooler water surfaces.
