distinguish between uric acid, urea and ammonia
Answer:
Explanation:
Ammonia is associated with aquatic animals; urea is associated with most terrestrial and semiterrestrial vertebrates, but rarely land invertebrates (Campbell et al., 1972); and uric acid is the major product of terrestrial invertebrates, birds and reptiles (Prosser & Brown, 1961).

Ciliated ependymal cells: A) help form the blood-brain barrier. B) circulate cerebrospinal fluid. C) form myelin in the brain and spinal cord. D) serve as wandering phagocytes during brain injury.
Ciliated ependymal cells: circulate cerebrospinal fluid.
Ependymal cells are a type of epithelial cell that is associated with the cavities of the body through which the cerebrospinal fluid circulates.
They are part of glial cells, which share space with neurons in the nervous system.They create the membranes that keep cerebrospinal fluid circulating through the ependymal canal of the spinal cord and the cerebral ventricles.For this, the ciliated structure that these cells present is essential for a correct movement of the cerebrospinal fluid, preventing it from spilling through other tissues and passing to areas of the body where it should not be.The cilia move rhythmically creating tiny currents for fluid to flow through the central nervous system.A small fraction of highly specialized and modified ependymal cells, called choroidal cells, are responsible for generating this essential fluid.Therefore, we can conclude that ciliated ependymal cells circulate cerebrospinal fluid.

Which diagram below shows the process of meiosis - Diagram A or Diagram B? How do you know? Explain all the details that prove you are correct.
From the diagram, meiosis is shown by the diagram in B in the question.
What is meiosis?Meiosis occurs when a cell divides in such a way that each daughter cell gets only half of the number of chromosomes in the parent cell.
Looking at the cell division in diagram B, we can see that there are only two chromosomes in each daughter nuclei out of the four chromosomes in the parent nuclei hence that us meiosis.

the genes stc1 and stc2, which share a common ancestor, are found in both zebrafish and humans. all four stc genes display similar patterns of exon and intron sequences. based on these facts, what is the most likely explanation for the origin of stc genes?
Based on these facts, we can state that the genes of the two organisms had a eukaryotic origin.
We can arrive at this answer because:
Despite having exons, prokaryotes do not have introns in their genomes.This means that if two organisms have the same sequence of introns and exons, they have a common ancestor, in addition to having their genes originated in a eukaryotic organism, which explains the sequence of introns.This means that the genetic expression of these two organisms has similarities, even if they are organisms with different biological processes.

Real-life fingerprinting differs from CSI techniques. While CSI portrays fingerprint analysis as rapid and foolproof, reality involves a slower and more nuanced process.
Real-life fingerprinting is a more involved process than the quick and ostensibly error-proof fingerprint analysis seen on CSI. CSI frequently depicts fingerprint matching as a straightforward database search that produces instant identification. However, in the actual world, fingerprint analysis is carried out by skilled experts who painstakingly check ridge patterns, minute spots, and other traits to assure precise matches. To avoid mistakes, this procedure can be time-consuming and requires knowledge.
In addition, the way that huge, networked databases are shown in CSI oversimplifies reality. Although modern technology makes fingerprint comparison easier, the vast network of records that are easily available is more fantasy than reality. Real-world law enforcement databases are subject to stringent guidelines and restrictions.

Type the correct answer in the box, Use numerals instead of words.
The diagram shows the approximate amounts of carbon, in gigatons (Gt) per year, that move through the primary processes
of the carbon cycle. The numbers in yellow are due to natural processes, and the numbers in red are the result of human
actions. Based on this diagram, complete the statements.
Human activities release 9 gigatons of carbon into the atmosphere each year.
Human activities remove 5 gigatons of carbon from the atmosphere each year.
Humans’ net contribution of atmospheric carbon to the atmosphere is 4 gigatons each year.
9 gigatonnes of carbon are released into the atmosphere annually by human activity. Each year, 5 gigatonnes of carbon are removed from the atmosphere by human activity.
Thus, Each year, 4 gigatons of atmospheric carbon are added to the atmosphere as a result of human activity.
A fundamental mechanism that controls the movement of carbon dioxide and other carbon compounds between the atmosphere, oceans, soil, and living things on Earth is known as the carbon cycle. The concentration of carbon in various reservoirs is influenced by a variety of natural and human factors.
Plants and other photosynthetic creatures take up about 120 Gt of carbon each year from the atmosphere through the process of photosynthesis (yellow).
Thus, 9 gigatonnes of carbon are released into the atmosphere annually by human activity. Each year, 5 gigatonnes of carbon are removed from the atmosphere by human activity.

Explanation:
Explain how the rate of cooling magma affects the size of
the crystal that form.
Answer: When magma cools, crystals form because the solution is super-saturated with respect to some minerals. If the magma cools quickly, the crystals do not have much time to form, so they are very small. If the magma cools slowly, then the crystals have enough time to grow and become large.

A(n) ______ gene is a type of gene that regulates development and that, when mutated, leads to organisms with structures in abnormal or unusual locations on their body.
A (n) homeotic gene is a type of gene that regulates development and that, when mutated, leads to organisms with structures in abnormal or unusual locations on their body.
A homeotic gene is a gene that intervenes in the developmental program that determines the location of structures along the anteroposterior axis.
The determination of the anteroposterior axis is one of the earliest events in development, and it guides the remaining processes of organogenesis. Once homeotic genes define the identity of the body segments, they code for proteins (homeodomain) that are responsible for activating other genes.These genes ultimately trigger the formation of the organs or limbs of this segment.Genes that control the position of organs have been called homeotic genes, while mutations that affect these genes are known as homeotic mutations.Therefore, we can conclude that homeotic genes are expressed in the body regions that will house the growing structures.

Explain what friction, corollas, and a low pressure gradient does to an air parcel. IF YOU CAN PLEASE GIVE A SHORT ANSWER.
Answer:
sorry big answer Answer with Explanation:
Coriolis Force - refers to the fictitious force that acts perpendicularly to the direction of a rotating motion.
Air parcel - refers to a body of air that is "imaginary."
Pressure gradient - the change in pressure across a given distance.
Pressure gradient force - the net force that is being directed from high pressure to low pressure.
When an air parcel is at rest, the pressure gradient force acts upon it. It will then move from high pressure to low pressure.
However, when the air parcel starts to be in motion, its direction will be changed with the help of the Coriolis force. Thus, it moves to the right side of the Northern hemisphere.
Once the speed of the wind increases, the change in direction of the air parcel increases. This happens until the pressure gradient force and the Coriolis Force are equal in magnitude. When this happens, the wind will start blowing parallel to the points of equal pressure. The wind will now then be referred to as in "geostrophic balance."
When friction happens, the geostrophic balance breaks. The flow of the wind will be slowed down. This means that the Coriolis force will also be lessened. The air parcel will then move towards the lower region.
