Answer:
Epidermis - barrier or protective layer
dermis- thermoregulator or maintain the temperature.
Explanation:
The two main skin layers that are present on the surface of the skin are the epidermis and the dermis layer (below the epidermis). These two layers are helpful in protecting from the excursion.
The epidermis layer is a protecting layer in general that acts as a barrier to protect the inner body from infection and also acts as the waterproofing layer.
The dermis regulates body temperature in an individual if the outer environment is too hot or cold, by sweat in a hot environment as it regulates the sweat glands.

Answer: See explanation
Explanation:
When volcanic eruptions occur, there are a lot of magma i.e. molten rocks that are formed under the volcano. This formation of the magma and their movement is referred to as magmatism. The magmatic process has an impact on the way magma melts.
Magmatism can be used as an acronym in the following way:
M - Molten
A - Assimilation
G - Geology
M - Mountain
A - Active volcano
T - Tectonics
I - Igneous

In humans, oxygen and carbon dioxide are exchanged between the alveoli in the lungs and the blood in the circulatory system. Which of the following processes allows for the exchange of these gases in the human body?
osmosis
simple diffusion
active transport
facilitated diffusion
Answer:
Simple diffussion
Explanation:
It is simple diffussion because it is the movement of gases or molecules of substance from a region of higher concentration to a region of lower concentration without using energy. Through this process gases are exchange between the alveoli of lungs and blood of the circulatory system. Carbon diffuses from tissues to lungs and oxygen diffuses from lungs to Tissues.
Answer:
diffusion

The diagram below represents part of a process that occurs in cells. Which process is represented?
The process in cells represented by the diagram would be translation or protein synthesis.
The translation is a process in cell biology during which the genetic codes in messenger RNA are decoded into their respective amino acids and linked together by peptide bonds. The process usually takes place in the ribosome of eukaryotic cells.
During translation, the genetic codes on mRNA are read and the amino acid corresponding to each code is released. The small ribosomal unit first binds to the mRNA at the beginning. Thereafter, the tRNA binds to the start codon on the mRNA before the binding of the large ribosomal subunit to complete the initiation complex.
More on the translation process can be found here: https://brainly.com/question/4013387

When Alfred Wegener first noticed that the continents fit together like puzzle pieces, this was
Answer:
- the discovery of the Pangaea Theory.
In 1912 Alfred Wegener (1880-1930) proposed that the continents were once compressed into a single protocontinent which he called Pangaea (meaning "all lands"), and over time they have drifted apart into their current distribution.
The east coast of South America and the west coast of Africa seem to fit together like pieces of a jigsaw puzzle, and Wegener discovered their rock layers “fit” just as clearly. South America and Africa were not the only continents with similar geology. Most all of the other continents fit together too.
Answer:
discovery of the Pangaea Theory.

how did wegner use climate evidence to support his hypothesis
Explanation:
Wegener used evidence of climate change to support his hypothesis. As a continent moves toward the equator, its climate becomes warmer. As a continent moves toward the poles, its climate becomes colder. But the continent carries with it the fossils and rocks that formed at its previous locations.

i’m terrible at this help me out please !!& tysm if you do !!
Answer:
Explanation:
Within all biological communities, energy at each trophic level is lost in the form of heat (as much as 80 to 90 percent), as organisms expend energy for metabolic processes such as staying warm and digesting food (see biosphere: The organism and the environment: Resources of the biosphere: The flow of energy).

Help please! DNA Assignment
Instructions: For this assignment, you will replicate DNA to make a complimentary strand of DNA. Then transcribe the complimentary DNA sequence into mRNA. Next, translate the mRNA molecule into the codes for specific amino acids using the amino acid chart on the last page. Lastly, address the reflection questions.

Questions:
Using what you have learned in the lesson and the experiment, answer the following questions in complete sentences.
What is the function of mRNA?
What is the function on tRNA?
Describe what happens during transcription.
Describe what happens during translation.
Explain how DNA is used to make a protein.
Answer:
DNA Replication:
Replicate the following strand of DNA:
Original DNA: A T G A A C CA T T C A G T A T G G
Complementary DNA:
Remember that the complimentary base pairs in DNA are Adenine-Thymine and Guanine-Cytosine, or A-T and G-C. This means that if the original sequence is:
A T G A A C C A T T C A G T A T G G
Then the compliment is (replace with the opposite base pairs):
T A C T T G G T A A G T C A T A C C
Transcription:
Transcribe the DNA to make an mRNA molecule
COMPLIMENTARY DNA:
mRNA Molecule:
So if our complimentary DNA (antisense stand) is T A C T T G G T A A G T C A T A C C then to transcribe, we basically create another complimentary strand, but for mRNA, we use Uracil instead of Thymine:
A U G A A C C A U U C A G U A U G G
Translation:
Translate the mRNA into the corresponding amino acids.
mRNA MOLECULE:
AMINO ACID:
Using the DNA sequence provided, determine the amino acids.
Next, take each codon (3-base set) to the table and record the corresponding protein:
A U G = Methionine (start)
A A C = Asparagine
C A U = Histidine
U C A = Serine
G U A = Valine
U G G = Tryptophan
ORIGINAL DNA: A T G G G T C T A G C G A A A G A T
Complementary DNA:
mRNA DNA Molecule:
Amino Acid:
And we do it all again:
A T G G G T C T A G C G A A A G A T = original DNA
T A C C C A G A T C G C T T T C T A = complementry DNA
A U G G G U C U A G C G A A A G A U = mRNA
A U G = Methionine (start)
G G U = Glysine
C U A = Leucine
G C G = Alanine
A A A = Lysine
G A U = Aspartate
