Answer:
Explanation:
It doesn't mean that temperatures everywhere are hotter. The angle at which sunlight hits Earth is one of the most important factors impacting the average temperatures in a region. Higher angle (more direct) sunlight warms Earth more effectively. Earth's axis is tilted by ~23°.
Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.

The two specific mechanisms of protein regulation in eukaryotic cells is DNA packaging and protein degradation.
TWO specific mechanisms of protein:DNA packaging: It loose or tight the chromatin that promoted or inhibited the transcription. Degradation of the protein: Proteases split down the proteins.Hence, The two specific mechanisms of protein regulation in eukaryotic cells is DNA packaging and protein degradation.

Explain why sometimes roots act as a source rather than a sink.
Answer:
Explanation:roots suck up nutrients
Roots can sometimes act as a source rather than a sink for glucose during unfavorable periods of growth.
What are sources/sinks?Sources are organs of plants where glucose is manufactured and sinks are organs of plants where glucose is stored.
Usually, the synthesis of glucose happens in leaves while some roots serve as storage organs for glucose.
When conditions are bad for glucose synthesis in leaves, storage roots sometimes become sources and send glucose to leaves for respiration.

Answer:
Ya antes del fin del siglo XIX Ehrlich había usado el término "complemento" para designar la actividad del suero que podía complementar la capacidad de los anticuerpos específicos de lisar bacterias. Pero es Jules Bordet quien descubre (1895) este componente, caracterizado frente a los anticuerpos por su termolabilidad. En 1907 Ferrata comienza a caracterizar algunos de sus componentes recurriendo a métodos de diálisis. Por motivos meramente cronológicos, los componentes iban recibiendo denominaciones a base de números tras la letra "C" conforme se iban descubriendo. Por esta razón, su orden de actuación no guarda en general relación con su nomenclatura.

short definitions for
Genetic code
mRNA
Mutation
Answer:
The genetic code is the code our body uses to convert the instructions contained in our DNA the essential materials of life. It is typically discussed using the “codons” found in mRNA, as mRNA is the messenger that carries information from the DNA to the site of protein synthesis.
Everything in our cells is ultimately built based on the genetic code. Our hereditary information – that is, the information that’s passed down from parent to child – is stored in the form of DNA. That DNA is then used to build RNA, proteins, and ultimately cells, tissues, and organs.
Like binary code, DNA uses a chemical language with just a few letters to store information in a very efficient manner. While binary uses only ones and zeroes, DNA has four letters – the four nucleotides Adenine, Cytosine, Guanine, and Thymine/Uracil.
Thymine and Uracil are very similar to each other, except that “Thymine” is slightly more stable and is used in DNA. Uracil is used in RNA, and has all the same properties of Thymine except that it is slightly more prone to mutate.
This doesn’t matter in RNA, since new RNA copies can be produced from DNA at any time, and most RNA molecules are intentionally destroyed by the cell a short time after they’re produced so that the cell does not waste resources producing unneeded proteins from old RNA molecules.
Together, these four letters of A, C, G, and T/U are used to “spell” coded instructions for each amino acid, as well as other instructions like “start transcription” and “stop transcription.”
Instructions for “start,” “stop,” or for a given amino acid are “read” by the cell in three-letter blocks called “codons.” When we talk about “codons,” we usually mean codons in mRNA – the “messenger RNA” that is made by copying the information in DNA.
For that reason, we talk about codons made of RNA, which uses Uracil, instead of the original DNA code which uses Thymine.
Each amino acid is represented in our genetic instructions by one or more codons, as seen below.

One of the most remarkable evidences for the common descent of all life on Earth from a single ancestor is the fact that all organisms use the same genetic code to translate DNA into amino acids.
There are a few slight exceptions to be found, but the genetic code is similar enough across organisms that when a gene from a plant or jellyfish is injected into a mammal cell, for example, the mammal cell will read the gene in the same way and build the same product as the original plant or jellyfish!

Explanation:
Missense mRNA is a messenger RNA bearing one or more mutated codons that yield polypeptides with an amino acid sequence different from the wild-type or naturally occurring polypeptide.

vision helps explain what the students saw?
Opponent process theory of color vision explains why they saw the image in different colors.
Opponent process theory of color vision is defined as the way the human
visual system processes information about color in an opposite manner. The
color viewed are usually complementary to each other.
The opponent process cells are located in the thalamus and in the example

What gene on plasmid act as a marker to select for the recombinant DNA
Genes that are preferably used in the plasmid need to be resistant from various antibiotic effects. The genes that are preferably used as selectable markers ( antibiotic resistant ) to select r DNA are: nptII, hpt, bar and gox.
What are markers ?Markers in the r DNA are actually the genes that are purposed to check if the nucleic acid sequence has been inherited in the host DNA or not.
Genes that are used in the markers need to be antibiotic resistant as it becomes easier to detect the plasmid containing bacteria when they are grown in the selectable culture media.
Thus nptII being resistant to amino glycoside antibiotics,gox to the glycophosphate and hpt gene to detect trans gene and bar in the self defense are selected most probably.
