Which of these is increasing the rate at which carbon dioxide is transferred from the geosphere to the atmosphere due to human activity?
a. Volcanic eruptions
b. Wildfires
c. Planting trees
d. Burning of fossil fuels
Answer:
D. Burning of fossil fuelsExplanation:
Option A; Volcanic eruptions happen all over the world. These release large quantities of gases. Although these release gases, these are not do to human activity. Volcanic eruptions are natural disasters. Since theses are natural, we can eliminate option A.
Option B; Wildfires also give off large amounts of gases. Wildfires burn through trees and will destroy nearly everything in its reach. Many wildfires have been started by humans, but they also can start naturally from something like lightning. These wildfires are being put out but not too quickly. So option B will can not eliminate it yet.
Option C; Planting trees can be done naturally. This process is being sped up by humans. Even though humans are a huge part of this, trees only slow down the rate in which carbon dioxide enters the atmosphere. So we can eliminate option C.
Option D; Burning fossil fuels is the main source of electricity for humans. About 60% of electricity is from fossil fuels. Upon burning fossil fuels, like coal, it releases huge amounts of gases. Mainly carbon dioxide. So we will not eliminate option D.
So we are left we B and D. Since option D involves more human activity than option B, D is the option that makes the most sense

what is the end product of the cell cycle
Answer:
The Meiosis Cell Cycle
Explanation:
Cell cycle is the process if cell division. The end product of cell cycle is two genetically identical daughters cells produced by cell division.
What is cell cycle?Cell cycle is the process occurring through different stages by which a cell divides to form its daughter cells. Various enzymes have significant roles in cell cycle.
A large number of DNAs in the chromosome of a cell undergo division where, the double stranded DNA separate and and each strand forms two new DNAs.
Therefore, at the end of a cell cycle through proper cell division, two genetically identical daughters cells are produced.

The statement describes the decreases in plant population sizes affect other populations in the area is herbivore population sizes decrease, then the carnivore population sizes decrease.
What is the difference between carnivores and herbivores?The three diets of animals include creatures that eat only plants, those that eat only meat, and animals that eat both plants and meat. Animals that eat plants exclusively are herbivores, and animals that eat only meat are carnivores.
Herbivores animals have broad, flat and short, teeth to grind and chew plant leaves, grains, and seeds. Carnivores animals possess long, sharp, and curved incisors and canines to tear flesh.
Teeth are suited for eating plants as well as meat. Deer, goats, zebras, etc. are the examples of the herbivores. Carnivores animals are lions, tigers, dogs, etc.

How does the shape of vomerine teeth help it preform its function?(holding prey) This question is about frogs in case there is any confusion
Answer:
The shape in V of the vomerine teeth is useful to hook the prey and hold it until the frog can swallow it.
Explanation:
In frogs, we can distinguish maxillary teeth, premaxillary teeth, and Vomerine teeth.
Vomerine teeth are projections of the vomer bone, located in the anterior part of the paladar and between the internal nares.
Vomerine teeth are specialized structures that help frogs catch and hold their prey. They are not involved in chewing or killing (frogs swallow the entire prey alive), just holding the creature before swallowing it.
These projections are covered by soft tissue. When the frog catches the prey, presses the tongue against the roof of your mouth. The vomerine teeth hook the prey and prevent it from slipping or wandering away.
The shape in V of the vomerine teeth is useful to hook the prey and hold it until the frog can swallow it.

Which of these conditions is most responsible for earth having an environment that supports life?
Answer:
Oceans regulating climate on land.
Explanation:
Oceans regulating climate on land is the most responsible for earth having an environment that supports life.
What is the global climate?The long-term distribution of heat and precipitation on Earth's surface is called global climate.
Ocean currents act much like a conveyer belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics.
Thus, currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.
Hence, option A is correct.

One letter from each parent are combined to create a genotype of one possible offspring. Example: G (from one parent) + g (from the other parent) = Gg (genotype of offspring)
Capital letters are dominant and lowercase letters are recessive
Dominant traits mask recessive ones so when the genotype of the offspring is Gg, it will be green because green is dominant over yellow

Answer:
1. Translation
2. Cytoplasm
3. Ribosome
Explanation:
Translation is a process whereby the cell uses a mRNA template to produce an amino acid sequence (protein). It is the second stage of gene expression in living organisms.

Answer:
The correct answer is - magnitude.
Explanation:
The earthquake is measure by the Richter scale in the unit of magnitude. It is the size of the earthquake in the length into the width and the slip. Magnitude is nothing but the distance or the power or extent of the earthquake.
There are different energy at different measures of magnitude on the Richter scale. Magnitude of 7.2 releases 30 times more energy than the energy releases by 6.2 magnitudes.

What are the inputs and outputs of cellular respiration and photosynthesis?
Answer:
Respiration is the reverse reaction of photosynthesis.
Explanation:
The inputs of cellular respiration are oxygen and glucose and the outputs of cellular respiration are energy in the form of ATP, water and carbondioxide while on the other hand, the inputs of photosynthesis are water and carbondioxide and the outputs of photosynthesis are glucose and oxygen. Glucose is stored in the body whereas some oxygen is used in the process of respiration while the rest is released in the atmosphere.
