Most nonrenewable energy resources are burned for us to use their energy. Which of the following is a nonrenewable energy source that is NOT burned?
A) nuclear
B) coal
C) natural gas
D) biofuels
Answer:
The correct answer is - A) nuclear.
Explanation:
Most of the non-renewable sources of energy are fossil fuels that are formed by the thermal decomposition of dead organic matter for million years and are converted to lighter hydrocarbons that contain high electrostatic potential energy.
Burning is the process that breaks the hydrocarbons into water vapor and CO2 with high amount of energy. Coal, natural gas and biofuels all three are fossil fuels and nuclear products are not fossil fuel but radioactive elements.

Imagine that an area was set aside to relocate orangutans displaced from their rainforest habitats. A solution like this would involve many groups of people and careful considerations. Review the questions below, then develop at least two additional questions that could be considered.
What do orangutans use for shelter in their native ecosystem?
How much area does a specific number of orangutans need?
Answer:
a) Orangutan prefer to shelter in leafy trees or only leaves
b) One territory is of size 9 sq. km.
Explanation:
a) Orangutans spend a large part of their life in tropical rainforest trees. They prefer to sleep on the bunch of green trees and protect themselves from harmful weather conditions by using broad leaves of rainforest trees.
b) Each individual territory of a male Orangutan is near about 9 sq. km. and can extend up to 15 square kilometer. In one territory only one male lives along with other females and young ones.
. A scientist discovers a new object in the Kuiper Belt and claims it is a dwarf planet. What would have to be true about the object for the scientist to be correct?
Answer:
The object would have to be spherical, orbit the Sun, and be traveling in a path with other objects.
Explanation:
Just outside of Neptune's orbit is a ring of icy bodies. We call it the Kuiper Belt. This is where you'll find the dwarf planet, Pluto. It's the most famous of the objects floating in the Kuiper Belt, which are also called Kuiper Belt Objects, or KBOs.
What method of gene regulation or gene expression is the most common for eukaryotic
genes?
transcription factors
miRNA
dicer enzymes
mRNA degradation
Answer:
Transcription factors
Explanation:
This is because Eukaryotic gene expression is regulated by transcription factors and RNA processing, which occur in the nucleus, and during protein translation, in the cytoplasm.
Transcription in eukaryotic cells is controlled by proteins . These proteins then bind to some specific regulatory sequences and try to control the activity of RNA polymerase. The Gene expression is regulate by transcriptional regulatory proteins . Also ,the packaging of DNA into chromatin and methylatiin indicate levels of complexity to the control of eukaryotic gene expression.

Can someone explain to me about how the pereodic table is used
Answer:
So basically the rows are called periods, and the columns are called groups. The groups show that those elements have similar characteristics. There are also different families such as the noble gases and alkali earth metals. The elements are placed where they are because of the atomic number which is directly equal to the number of protons there are. The atomic mass is the number of both protons and neutrons. Also, even though the number of protons can be equal to the number of electrons, that isn't always the case. It could be an isotope which is basically for when an element or atom isn't neutral.

In class your professor shows you an MRI scan of a primate brain. The professor points out the relatively large size of the olfactory bulb beneath the frontal lobe. This suggests to you that Group of answer choices this primate shows a derived trait for an enhanced sense of smell as this trait is not commonly observed in mammal species this is a species of prosimian because it has an increased reliance on vision this is a species of anthropoid because it has an increased reliance on vision this primate must be a species of prosimian, as that suborder of primates still relies heavily on the sense of smell for many aspects of daily life
Answer:
this primate must be a species of prosimian, as that suborder of primates still relies heavily on the sense of smell for many aspects of daily life
Explanation:
The suborder prosimian belongs to primate mammals and is at a level inferior to the real monkeys.
Prosimians characterize as having an elongated head that culminates in the snout. They have big eyes with modifications in the retina that improve sight during the night. They are quadrupeds with a svelte body and soft hair. Their tail is long but not prehensile. They move from tree to tree by making use of their extremities. They have a dental comb to clean themselves and others.
Their snout is humid, and the sense of smell is much more developed than in other primates. They are the primates with the greatest sense of smell. Their olfactory bulb and glands are remarkably developed in concern with other primates. With their tree and nocturnal habits, they depend a lot in this sense to move, relate, be aware, and feed.

Most of the Earth’s freshwater is found in __________.
A)
oceans
B)
lakes
C)
groundwater
D)
icecaps and glaciers
E)
swamps
Answer:
D) icecaps and glaciers
Explanation:
Edge
The answer is D. Icecaps and Glaciers.
The reason is because iceburgs/glaciers contain huge chunks of ice. Glaciers have around 0.1 square kilometers, or 25 acers.Around 101171.411 sq meters, of ice. Iceburgs are around 5 meters, or 16 feet (across) Again,of ice.
We know that to make ice, you freeze water, by putting it in a cold enviorment, or simply putting a glass of water in you freezer.

The brown-colored bones in each animal help to connect their limbs to a specific joint in the torso, or middle of their body. What type of structure do these bones represent, and what is their significance in terms of evolutionary relationships?
Answer: These structures connect their limbs to a specific joint in the torso or in the middle of their body. These structures can be identified as homologous, they are morphologically similar or possibly they derive from a common ancestral structure.
Explanation:
The brown color bones in animal help to connect limb homologous structures that connect their limb to the specific joint in the torso, this and having an evolutionary relationship.
What are bones?If two bones split where they meet at a joint, it is termed a dislocation. The place where two bones connect and therefore can move is called a joint.
A displaced joint is one where the bones are out of alignment with each other having a significant role in evolution.
Despite their similar arrangements and being formed in a similar way throughout embryonic development, these structures have slightly different shapes and purposes, they refer to them as homologous structures.
Therefore homologous structures have an evolutionary relationship to connect brown-colored bones connect limbs to joint torso.

Explanation:
the fossil fules are used as energy sources but they cause pollution and are what
Answer:
The correct answer is - non-renewable.
Explanation:
The non-renewable source of energy is the source of energy that can not be replaced naturally in the manner and the pace of the consumption of these sources. Nuclear, oil, fossil fuels, natural gases and other are an example of these type of energy source.
Fossil fuels were generated due to the decomposition of the dead plants and animals within the Earth over millions of years therefore these are called fossil fuels. These fuels are cause pollution by burning.
the rate of the Earth's and moon's rotation and revolution constant?
The moon orbits the Earth once every 27.322 days. It also takes approximately 27 days for the moon to rotate once on its axis. As a result, the moon does not seem to be spinning but appears to observers from Earth to be keeping almost perfectly still. Scientists call this synchronous rotation.
If data for the growth of this bacterial population continued to be recorded, would the data point at 60 hours be above or below 37 million? Support your answer.
Answer:
Above 37 million
Explanation:
Explanation in picture below
Growth of bacterial cultures is defined as an increase in the number of bacteria in a population rather than an increase in the size of individual cells.
Thus, Bacterial population growth occurs geometrically or exponentially: in each division cycle (generation), one cell produces 2 cells, then 4 cells, then 8 cells, then 16, then 32, etc.
The relationship shows that the average generation time is constant and the growth rate of the bacterial population is proportional to the number of bacteria at any given time.
This relationship is valid only during the period when the population grows exponentially, ie. in the logarithmic phase of growth. Therefore, graphs showing the growth of bacterial cultures are plotted as the logarithm of the number of cells.
Thus, Growth of bacterial cultures is defined as an increase in the number of bacteria in a population rather than an increase in the size of individual cells.

Cory states the following argument about the evolution of aardvarks and anteaters.
"Aardvarks and anteaters both use long, sticky tongues to capture and eat ants or termites. Aardvarks are native to Africa, while anteaters are native to the Americas. However, their similarities provide evidence that both groups of species evolved from a common ancestor that used its tongue to eat ant-like insects."
Which claim, if supported by evidence, would provide the strongest counter-argument AGAINST Cory's argument?
A. The tongues and diet of aardvarks and anteaters are an example of convergent evolution.
B. The tongues and diet of aardvarks and anteaters are an example of adaptive radiation.
C. The Americas and Africa were once joined together, and animals roamed freely between the two lands.
D. A long, sticky tongue evolved in response to the tunneling behavior of ants, an example of coevolution.
