how do eumelanin and pheomelanin affect our skin color?

Answers

Answer:

There are two types of melanin--eumelanin and pheomelanin. In general, the more eumelanin in your skin, the darker your skin will be. People who make more pheomelanin than eumelanin tend to have lighter skin with freckles. Like many other traits, the amount and kind of pigment in your skin is controlled by genes

Niagara Falls is a big waterfall on the border of Canada and the United States. Each year the edge of the waterfall moves back a couple of centimeters because the water is breaking apart the rocks on the edge. What is this an example of? Why?

Answers

This is an example of erosion. Erosion is when something is “washed” away (or eroded) over time (usually by water). The rocks are breaking apart because the rushing water is slowly eroding the edge a couple of centimeters every year.

Which statement best describes the initial process of N-linked glycosylation in the endoplasmic reticulum

Answers

Answer:

The oligosaccharide is assembled on the lipid carrier at the membrane of the ER

Explanation:

N-linked glycosylation consists of the attachment of an oligosaccharide (glycan) to a nitrogen atom of the asparagine (Asn) residue in the protein. N-linked glycosylation is a key posttranslational modification (PTM) capable of controlling protein structure and function, this pathway takes place in the plasma membrane in archaea organisms and in the membranes of the endoplasmic reticulum (ER) in eukaryotic organisms. In eukaryotic cells, the N-linked glycosylation conserved pathway consists of two steps. In the first place, the oligosaccharides are assembled on a lipid carrier called dolichyl pyrophosphate localized in the endoplasmic reticulum (ER). The dolichyl-phosphatase is a hydrolase enzyme that acts on phosphoric monoester bonds. Second, the oligosaccharides are modified by specific glycosyltransferases that transfer these molecules to selected Asparagine (Asn) acceptor residues of polypeptide chains that have entered the lumen of the ER. These N-glycans are firstly assembled as a dolichol-linked precursor oligosaccharide at the cytoplasmic face of the ER.

Answers

Answer:

Answer below

Explanation:

The eight steps of the citric acid cycle are a series of redox, dehydration, hydration, and decarboxylation reactions. Each turn of the cycle forms one GTP or ATP as well as three NADH molecules and one FADH2 molecule, which will be used in further steps of cellular respiration to produce ATP for the cell.

consider the endosymbiont theory and the fact that chloroplasts contain dna molecules. given that chloroplast DNA has genes,

Answers

Answer/Explanation:

The endosymbiotic theory is the idea that eukaryotic cells evolved from the fusion of two prokaryotic cells that formed a symbiotic relationship, with one living inside the other.

An endosymbiont is one organism that lives inside another one.

The existence of mitochondria and chloroplasts, which contain their own DNA and ribosomes, supports this theory. Mitochondria are chloroplasts were once free-living organisms,  they were prokaryotes that ended up inside of other cells.

Mitochondria and chloroplasts have genes that are very similar to the genes of prokaryotes. Their membranes look like the prokaryotic cell membrane, and they divide  in similar ways.

Both strands of the DNA double helix contain nitrogenous bases held together by hydrogen bonds. In DNA, the sequence of nitrogenous bases varies widely. What is the significance of the nitrogenous bases?

A. They determine the amino acids in the proteins synthesized.
B. They prevent mutations from occurring in the process of DNA replication
C. They help complete the sugar-phosphate backbone of DNA molecules.
D. The amount of adenine and cytosine determines the length of the gene on a DNA molecule.

Answers

Answer:

A

Explanation:

Essentially, in the process of protein synthesis, there is first transcription where mRNA is synthesized off of a DNA strand with complementary nitrogenous bases. After processing occurs (in basic terms the mRNA is literally processed) and the mRNA strand leaves the nucleus, it attaches to a large and small ribosomal subunit (a ribosome) where translation occurs. The gist of it is when the mRNA strand is being read by the ribosome. tRNA will come over and bind temporarily bringing with it a specific amino acid, starting the formation of the polypeptide/amino acid chain. Nitrogenous bases play into this as the sequence of the nitrogenous bases is what determines what tRNA will bind onto it which determines which amino acid is brought. More specifically, this deals with the codons of the mRNA and the corresponding anticodons with the tRNA, which is a bit of a more specific topic.

The nitrogenous bases help complete the sugar-phosphate backbone of DNA molecules. The correct option is C.

What is DNA?

DNA, also renowned as deoxyribonucleic acid, is a complex molecule that includes all of the information required to construct and retain a lifeform.

DNA is found in the cells of all living things. In real sense, as in almost every cell in a multicellular organism contains the entirety of the organism's DNA.

DNA is composed of chemical key components known as nucleotides. These building blocks are composed of three components: a phosphate group, a sugar group, and one of four different types of nitrogen bases.

Nucleotides are linked together in chains, with the phosphate and sugar groups alternating.

Thus, the correct option is C.

Why are Canada’s Evergreen Forests considered “Earth’s Northern Lungs”? (think about the photosynthesis equation)

Answers

Answer:

Although trees have responded to global warming in the past‐ to temperatures higher than they are now- the rate of change predicted in the 21st century is likely to be unprecedented. Greenhouse gas emissions could cause a 3°-6°C increase in mean land surface temperature at high temperatures and temperatures latitudes. Despite this, few experiments have isolated the effects of temperature for this scenario on trees and forests. This review focuses on tree and forest responses at boreal and temperate latitudes, ranging from the cellular to the ecosystem level. Adaptation to varying temperatures revolves around the trade- off between utilizing the full growing season and minimizing frost damage through proper timing of hardening in autumn and dehardening in spring.

Answer:

The moon's gravitational pull on the Earth is the main cause of the rise and fall of ocean tides. The moon's gravitational pull causes two bulges of water on the Earth's oceans—one where ocean waters face the moon and the pull is strongest and one where ocean waters face away from the moon and the pull is weakest.

Explanation:

"B" as labelled in the above is the zone of inhibition.

The Zone of Inhibition is actually a test which is used to assess antimicrobial activities of a material or solution in relation to an micro-organism as a target. It is also known as Kirby-Bauer Test. It measures the antibiotic resistance and also used to inhibit microbial growth.

At the Point B, microbes can not grow in there; they are inhibited.

In the test, if bacterial strain or any other strain is susceptible to the antimicrobial agent, a zone of inhibition appears. If it shows resistance to that agent, then no zone is evidential.
