The correct pairing of human activity with the greenhouse gas it increases is: Deforestation and methane.
What is deforestation?Deforestation refers to the deliberate or widespread removal of trees and vegetation from forests or woodland areas, leading to the conversion of forested land into non-forest uses. It involves the permanent destruction or clearance of forests, typically for purposes such as agriculture, logging, urbanization, or infrastructure development.
Deforestation has significant environmental, social, and economic implications. It contributes to habitat loss, biodiversity decline, soil erosion, and climate change. Forests play a crucial role in carbon sequestration, regulating the water cycle, and providing habitats for countless species.
Deforestation disrupts these ecological processes and can lead to the loss of invaluable ecosystem services. Efforts to combat deforestation involve sustainable land management, reforestation initiatives, and the promotion of responsible forestry practices.

Answer:
The answer is D
Explanation:
A researcher attempts to use a segment of ribosomal RNA as a molecular clock to calculate the date of the last common ancestor of two species. He finds that the two species diverged from a common ancestor 150 million years ago. These particular species have abundant fossil records that strongly suggest that these species diverged 100 million years ago. Which of the following answer choices best describes a reason for the discrepancy in the date of the last common ancestor of these species?
A. Ribosomal RNA is not a reliable molecular clock and should not be used for dating.
B. The neutral mutation rate used in calculating the last common ancestor date may not have been accurate.
C. It is highly likely that the two organisms did not share a common ancestor, so the results are invalid.
D. A large portion of the ribosomal RNA is not vital to survival, so it is not likely to be well preserved.
Answer:
B
Explanation:
It is B because the mutation rate should not have been accurate if it showes that they diverged 150 million years ago. But the abundant fossil records show that it diverged 100 million years ago.

What is molecular docking?In structural molecular biology and computer-assisted drug design, molecular docking is an important technique. The purpose of ligand-protein docking is to anticipate a ligand's most common binding mode with a protein having a known three-dimensional structure.What is dating? Carbon dating is used to determine the age of ancient material such as an archaeological or paleontological specimen .A molecular clock estimates how long it has been since similar species separated from a common ancestor based on DNA sequences (or the amino acid sequence of proteins encoded by DNA).

State reason(s) why ash should or should not be used in making compost
Answer:
Fireplace ashes for compost can be used to help maintain the neutral condition of the compost. It can also add nutrients to the soil. Decomposing materials in the compost pile can become somewhat acidic and wood ash can help offset this, as it's more alkaline in nature. But Adding too much ash to the pile can be detrimental to the makeup of the compost because of its alkalinity. Ashes tend to raise the soil pH, so you shouldn't use it directly on plants, especially acid-loving ones like rhododendrons, azaleas, and blueberries. Also, in high amounts, wood ash can inhibit plant growth by restricting nutrients, like iron.

Which of these is true of fetal development by the end of the third trimester?
A. The placenta is absorbed by the uterus.
B. The fetus can survive outside the uterus.
c. All development is complete.
D. All growth is complete.
Answer:
B. The fetus can survive outside the uterus.
Explanation:
The third trimester starts in the wekk 28 (month 7 ) of fetal development and lasts until the birth pf baby, that is around week 40 (month 9) of pregnancy.
There are several changes occur in the thrid trimester of the fetal development such as hearing and visual has developed and the internal organs including the heart, lungs, intestines and stomach has developed enough.
So, at the end of fetal development of the third trimester as all the body organs have grown and developed, a fetus can survive outside the uterus.
The correct option is B.
Answer:
Option B
Explanation:
During the third trimester, the fetus continues to grow in weight and size however the body systems finish maturing. In fact, both mother’s body and the fetus continue to grow and change. Lungs, brain and kidneys keep maturing. Fetus position itself head-down and is 6 to 9 pounds in weight. Skull bones are soft but fetus become able to suck its thumb and cry. By 38 to 40 weeks, the lungs have matured fully . The end of third trimester marks the period when the fetus is ready for delivery. Hence option B is the correct answer

How can you decrease the effort force needed to push a weight to the top of the ramp? A) cover the surface with carpet B) increase the length of the ramp C) increase the height of the ramp D) decrease the length of the ramp
Answer:
B) increase the length of the ramp
Explanation:
Less force is needed to move the object over a longer distance.
Answer:
You can decrease the effort force needed to push a weight up the ramp if you increase the length of the ramp. You could also decrease the height of the ramp.Lengthen the ramp, decrease the mass of the object, use a machine can you decrease the effort force needed to push a weight
Explanation:
A ramp is an example of an inclined plane. Think back to the example of the ramp and the moving truck. The ramp reduced the amount of force needed to lift the box by moving it over a greater distance. The longer an inclined plane, the less force is required to move an object upward.

In cycles of matter when rock has been exposed for mining, the answer is water. Thus, option A is correct.
Can readily transport nutrients from rock to aquatic ecosystems. Runoff that carries excess nutrients can cause algae blooms.The effects of soil erosion. Thus, option B is correct.
What is soil erosion?The removal of the top of the soil by water, wind and human activities has been called soil erosion. The reason due to which soil erosion takes [place is that trees should be planted in several rows to check the speed of the wind. This reduces soil erosion because of wind. Because the rivers cause soil pollution, dams are built in the upper course of the rivers to check soil erosion.
Soil erosion has happens when the dirt has been exposed to the high winds, heavy rains, and rushing water. In few circumstances, human activities, like farming and land clearance, expose soil to erosion. Soil erosion has been considered as the removal and transfer of the top layer of soil from its original location to another due to high winds and fast-running precipitation.
Therefore, Both rock and bodies of water are considered a type of reservoirs. Thus, option C is correct.
In cycles of matter when rock has been exposed for mining, the answer is water. Thus, option A is correct.
Can readily transport nutrients from rock to aquatic ecosystems. Runoff that carries excess nutrients can cause algae blooms.The effects of soil erosion. Thus, option B is correct.
