Answer:
Conversion of forest to cropland or pasture decreases the rate at which carbon is taken up by plants.
Cut trees are often burned, and this releases carbon into the atmosphere.
Explanation:
First of all, deforestation is the conversion of forests to non-forest uses. Non-forest uses include agriculture, industrial development, infrastructural development, etc.
Forests are sinks for carbon and their removal or conversion to non-forest uses means that less carbon would be fixed through photosynthesis. Slash and burn agricultural practice also leads to the emission of carbon dioxide into the atmosphere.
Thus, more carbon dioxide would be present in the atmosphere as a result of deforestation and burning. This carbon dioxide is a greenhouse gas that causes the warming of the planet, a phenomenon that results in the change of climate of the planet.
Hence, the conversion of forest to cropland leading to a decrease in the rate of carbon fixation and the emission associated with burning both contribute immensely to global climate change.
what is information?
Answer:
Information can be thought of as the resolution of uncertainty; it is that which answers the question of "What an entity is" and thus defines both its essence and the nature of its characteristics. The concept of information has different meanings in different contexts.

A group of students wants to build a ramp to move boxes from the floor up to a stage. How can the students reduce the amount of effort needed to push the boxes up the ramp?
Question 8 options:
by making the ramp as long as possible
by making the ramp’s height and length equal
by building the ramp out of a lightweight material
by covering the ramp’s surface with a soft rubber mat
If students wants to reduce the amount of effort needed to push the boxes up the ramp, it is possible by making the ramp’s height and length equal, hence option 2 is correct.
Why does it take more force to move a heavy box up a ramp?If students moves a heavy box up a ramp, there is so much friction on the undersurface of the box when going up a ramp.
To reduce the amount of effort needed to push the boxes up the ramp by making the ramp’s height and length equal, in second option by making the ramp as long as possible needs more effort.
In the fourth option, by covering the ramp’s surface with a soft rubber mat, make it harder to slide up boxes.
Therefore, by making the ramp’s height and length equal, it is easier to reduce the amount of effort.

While some mutations can benefit an organism, others are harmful and can lead to cancer. Which of the following best describes how mutations can cause cancer in an organism?
O Cell division becomes uncontrolled when mutations occur in genes that regulate cell division.
O Cells with mutations outnumber and consume normal cells that do not have mutations,
O A mutation can attack a cell's DNA and cause an autoimmune response in the cells.
+
O Mutations cause cells to become unable to divide and the cells die in masses, forming tumors.
Answer:
Cell division becomes uncontrolled when mutations occur in genes that regulate cell division.
Explanation:
Answer:
The answer is "A."
Explanation:
Cancer develops when the cells in the body are constantly dividing uncontrollably. In humans, cancer is often the result of a negative mutation genetically. The other answers are wrong and do not match the way cancer forms. So, A will be your answer.
A few minutes of incubation at room temperature in the laboratory will inactivate HIV, but the flu virus is still active after incubating for several hours. What are the practical consequences of these findings?
Answer:
Flu virus cause more infection than HIV virus.
Explanation:
The practical consequences of these findings indicates that the flu virus has more chances to cause infection in the person due to its active nature as compared to HIV virus which is inactive after incubation. This active nature of the flu virus results in the infection of more people in the world as compared to HIV patients so we can conclude that flu virus is more common than HIV virus due to its activeness.

In a histology lab a scientist observes the following features under the microscope. Which of these
observations supports cell theory?
I. Cardiac cells are joined by gap junctions and contain three nuclei.
II. Mature platelet cells do not contain a nucleus, but do contain mitochondria.
III. Spermatogonia undergoing mitosis.
IV. The bulk of tissue samples from endocrine glands contain cells as their main building blocks.
option III and IV supports cell theory.
The three essential concepts of cell theory are that: 1. cells are the fundamental building block of life; 2. living creatures consist of one or more cells; and 3. cells originate from preexisting cells.
Hint #2 2 / 4
In cell theory, the quantity of nuclei is not taken into account.
Hint #3 3 / 4
A new cell is produced during the process of cell division known as mitosis. This idea—that cells form from already-existing cells—is exact.
Hint #4 4 / 4
III and IV are both illustrations of cell theory in the actual world. Mitosis, which is the process by which preexisting cells divide to form new ones, demonstrates how cells make up living things, as does the cellular makeup of glands.

The recombination frequency between linked genes A and B is 40%, between B and C is 20%, between C and D is 10%, between C and A is 20%, and between D and B is 10%. What is the sequence of the genes on the chromosome?
Answer:
ACDB (or BDCA)
Explanation:
The linked genes A and B have a greater frequency of recombination (40%) and therefore they are found furthest away on the chromosome. Conversely, the smaller distance is between D and B, which exhibit a lower frequency of recombination (10%), while C is localized at the same physical distance of both A and B (20%), so the physical map is ACDB.

How is the DNA sequence AATTA replicated in a new strand during semiconservative replication?
Answer:
According to the semi-conservative DNA replication, the AATTA sequence is transcribed into a new strand as TTAAT, taking into account the complementarity of nitrogenous bases.
Explanation:
Semi-conservative DNA replication means that two molecules are obtained from a double-stranded DNA molecule, each with an original strand and a new strand.
The DNA is composed of sequences of nitrogenous bases, which are adenine (A), guanine (G), thymine (T) and cytosine (C). The bases of one chain are matched with the bases of another, according to the complementarity of nitrogenous bases, where:
Adenine is complemented with Thymine A=TGuanine is complemented with Cytosine G≡CThen, for the sequence AATTA of the strand DNA mold, the sequence on the new strand would be complementary, i.e., TTAAT.
