Answer:
One-fourth of the original carbon-14 isotope would be found in the wood today.
Explanation:
The half life of carbon-14 7000 years
Since the tree died and became a fossil 14000 years ago, number of times the tree has undergone decay in 14000 years = 14000/7000 = 2
Therefore, the carbon-14 would have undergone decay twice or passed through two half-lives
After one decay, 1/2 of the original sample remains
After another decay, 1/2 * 1/2 = 1/4 of the original sample remains.
Therefore, one-fourth of the original carbon-14 isotope would be found in the wood today.

How are plants affected by an increase in thermal energy on Earth?
Explanation:
When temperature rises plants grow taller in order to cool themselves off their stocks become taller in her levels become narrower and grow farther apart
"Plants become higher as a means of cooling down when temperatures rise. Their leaves also enlarge and spread wider apart as their stalks grow longer.
How are plants affected?Animals are significantly less sensitive to temperature changes than plants are. Additionally, they are unable to look for places that are hotter or colder.
Plants become higher as a means of cooling themselves off when temperatures rise. Their leaves also enlarge and spread wider apart as their stalks grow longer.
More than simply plant biodiversity is impacted by global warming; it also changes how plants grow.
Therefore, Plants become higher as a means of cooling down when temperatures rise. Their leaves also enlarge and spread wider apart as their stalks grow longer.

Answer:

Explanation:
Construct a hypothesis to explain the differences you might observe when comparing the karyotypes of normal human
cells versus cancerous cells
Answer:
The karyotype of cancerous cells is abnormal due to the mutations in the DNA. The cell division that occurs in the cancerous cells is similar to the normal cell division. The only difference lies in the check points. The cancerous cells skip the checkpoints where the errors are checked.
Further Explanation:
A hypothesis is the primary explanation that is formed on the basis of limited evidences that support the investigation.
The picture of a person’s chromosome is known as karyotype. The karyotype of a person can be determined by isolation of chromosomes followed by staining and examination of the chromosomes under microscope. The WBC chromosomes are usually isolated, stained and examined. The examined picture under a microscope is taken and the chromosomes are then arranged in the decreasing order of chromosome size. In a normal cell, the mitosis cell division also known as equational cell division is responsible for the increase in the number of cells. The number of chromosomes after the mitotic cell division remains equal to the initial number of chromosomes. Thus, known as equational cell division. In cancerous cells, the abnormal mitosis cell division occurs in which the cell skips the checkpoints which causes abnormal number of mitotic divisions.
Thus, the karyotype of cancerous cells is abnormal due to the mutations in the DNA. The cell division that occurs in the cancerous cells is similar to the normal cell division. The only difference lies in the check points. The cancerous cells skip the checkpoints where the errors are checked.

Explanation:
Compare and contrast the intertidal, neritic, and oceanic zones.
Answer:
Found this off of google, "The ocean can be divided into zones based on depth and distance from shore. Intertidal Zone The area of shore between the high-tide and low-tide lines is called the intertidal zone. ... Neritic Zone The area of the ocean from the low-tide line out to the edge of the continental shelf is the neritic zone."
Hope this helps!
Have a great day and stay safe! :) :D
The Neritic Zone is from the low tide mark and slopes steeply down to the extremity of the seafloor. The Oceanic Zone is the entire ocean from the extremity to the bottom of the Neritic Zone. The Zone where the ocean meets the land between high and low tides is the intertidal zone.
In marine aquatic environments, the intertidal zone is the area between the foreshore and the seabed where the air is exposed to the water at low tide and the water is submerged at high tide. It is also referred to as the littoral zone.
In the neritic zone, the sun’s rays reach all parts of the zone and the nutrients in the water are abundant. Sunlight reaches only a few parts of the open ocean zone and the water is nutrient-poor.

Whatstatement accurately names and describes the function of the organelle labeled B?
The correct answer is Option A .
Organelle B = Mitochondrion.
A mitochondrion converts food into energy for cellular functions.
Explain functions of mitochondrion?According to the diagram, the organelle labelled A absorbs solar light energy and transfers it to the mitochondria ( organelle labelled B )The energy that the mitochondrion receives is put to use by the organelle to break down the food that has been consumed and produce the energy (ATP) that powers every other cell.Thus, we can deduce that the statement "A mitochondrion produces energy from food to power cellular processes" accurately describes the function of organelle B.Oxidative phosphorylation, which produces ATP using the energy released during the oxidation of the food we eat, is the traditional function of mitochondria. For the majority of biochemical and physiological processes, including growth, movement, and homeostasis, ATP is used as the main energy source in turn.To learn more about mitochondrion refer to :

which feature of earth's crust is an effect of compression over a long period of time?
A. Tilting of rock layers
B. Fault-block mountains
C. Folded mountains
D. Motion at transform faults
Answer:
Folded mountains
Explanation:
it's correct
The feature of the earth's crust that is an effect of compression over a long period of time is folded mountains, which is in Option C, as the folded mountains are formed when rock layers are subjected to compression over a long period of time.
What is a folded mountain?Folded mountains are formed when rock layers are subjected to compression over a long period of time. This causes the rock layers to buckle and fold, forming large, uplifted mountain ranges, and the process of folding can occur at convergent plate boundaries, where two tectonic plates are moving towards each other and causing compression in the rock layers in between them. The Himalayan mountain range, which spans several countries including India, Nepal, and China, is an example of a folded mountain range that was formed by the collision of the Indian and Eurasian tectonic plates.
As a result, the folded mountains in Option C are a feature of the earth's crust that is the result of long-term compression.
