c.it is the most abundant component
d.it is usually called additve
Answer:
C. it is the most abundant component
Explanation:
A heterogeneous mixture is simply any mixture that is not uniform in composition - it's a non-uniform mixture of smaller constituent parts. By contrast, a mixture that is uniform in composition is a homogeneous mixture.

MRNA strand: TATACGA
Answer:
The mRNA strand for TATACGA is UTUTGCT.
Explanation:
The DNA bases are adenine (A), thymine (T), guanine (G), and cytosine (C). Each of these bases pairs with a complimentary one. Adenine pairs with thymine, and cytosine pairs with guanine.
During transcription, the DNA is transcribed into an mRNA strand. The mRNA has the same complementary bases of the DNA strand, with the difference that instead of having adenine base the complementary base of thymine, it has uracil (U). When we interpret the DNA strand TATACGA, the mRNA will be adenine (A) paired with the DNA's thymine (T), uracil (U) paired with the DNA's adenine (A). Then the same sequence repeats itself. After that, guanine (G) pairs with DNA's cytosine (C), cytosine (C)pairs with the DNA's guanine (G), and lastly, thymine (T) with the DNA's adenine (A).
Explain the three principles of the cell theory
Answer:
The three tenets to the cell theory are as described below: All living organisms are composed of one or more cells. The cell is the basic unit of structure and organization in organisms. Cells arise from pre-existing cells.
Explanation:
Can I have brainliest?
Answer:
Answer: 1) All the living organims are compound by one or more cells . 2) The cell is the structural and functional basic unit of life. 3) All cells are originated from other cells.
Explanation: Cell theory describes the characteristics of living organisms and was proposed and refined by many scientists like Schwann and Schleiden. The first principle describes the constitution of living organisms, all of them, unicellular or multicellular are compund by cells. The second principle says that cell is the unit of life in fuctions as metabolism and structural as in tissues. The third principle says that cells can only be generated by division of preexisting cells.

Q29. How has the Sun caused changes in global and hemispheric temperatures over
the past thousand years?
Answer:
the global average surface temperature has increased over the 20th century by about 0.6 degrees C
In the last thousand years, solar activities have caused a decrease in temperature in the northern hemisphere.
We can arrive at this answer because:
The changes in the sun were very important for the rise in temperatures during the 1000's to the 1100's.However, over the years this activity and changes in solar production caused this temperature to drop, especially in the northern hemisphere.Even though this decrease in temperature was something small and subtle, in the last thousand years it has been established in the region above the equator.This process explains how global warming was not the result of changes in solar production, as this change caused a cooling. In this case, this confirms that global warming was caused by the accumulation of greenhouse gases caused by human actions.

In fruit flies, eye color is a sex-linked trait. Red is dominant to white.
What are the sexes and eye colors of flies with the following genotypes:
Look at the picture
30 points and braininess
Answer:
The correct answers are:
1 a. X^RX^r - red eye color female
b. X^RX^R - red eye color female
c. X^RY - red eye color male
d. X^rY - white eye color male
e. X^rX^r - white eye color female
(2nd part can also be answered by above)
Explanation:
It is given that the eye color is a sex-linked character where Red eye color is dominant over white eye color in fruit flies. Sex-linked characters are the character that is a similar inheritance pattern except in the case of the male as there is a Y chromosome that does not carry the gene for the eye color trait so the trait will depend on the allele present on a single X chromosome in males.
On the basis of this, the sex and color of eyes will be:
a. X^RX^r - red eye color female - Dominant character will mask the recessive white color and two copies of X which means female.
b. X^RX^R - red eye color female - both copies are dominant so red-eye color will be expressed and two copies of the X chromosome that means female
c. X^RY - red eye color male - One X and one Y chromosome that means male and only dominant allele present so red eye color.
d. X^rY - white eye color male - Only allele that is present is recessive with one Y chromosome that means male with white eye color.
e. X^rX^r - white eye color female - two X chromosomes with recessive allele which means white eye color female.
Dominance refers to when an allele masks the effect of another allele.
Red is dominant to white
The sexes and eye colors of flies with the following genotypes:
XR Xr - Female with red eyes.
XR XR - Female with red eye
XR Y - Male with red eye
Xr Y - Male with white eye
Xr Xr - Female with white eye
White eyed male - Xr Y
white eyed female - Xr Xr
Red eyed female (heterozygous) - XR Xr
Red eyed male - XR Y

3. What would happen if they crossed yellow jellyfish with coober Complete
the Pummert squire to help you determine the probability for each color of
Sive the possible genotypes and phenotypes for the offspring
What percentage of the offspring would be yellow?
What percentage would be blue
What percenge would be onders green
Answer:
We know that the color of jellyfish is controlled by codominance inheritance pattern and yellow Y and blue B are two alleles and in case of heterozygous the goober or green color occurs then,
If Yellow jellyfish is crossed with goober, that is, YY X YB.
the punnett square will be -
Y Y
Y YY YY
B YB YB
The possible genotype of offspring will be YY, and YB and therefore, the possible phenotype of offspring will be Yellow, and Green. The Percentage of yellow offspring will be 50% as two out of four are dominant for Y allele and two heterozygous conditions that is 50 % and as there are two copies B alleles are not present so zero percent of blue color.

Why is the 3-dimensional shape of a macromolecule (ex: protein) important to know from the perspective of understanding
the molecular basis of human disease? 2 pts
A/ Mutations in genes that cause a change in amino acid primary sequence can cause a change in the protein's function in a
cell. For example, it can cause the protein to mislocalize; the protein is now recruited to a specific site in the cell, like the
nucleus, where it can cause cellular dysfunction.
B/ If the protein is an enzyme, the 3-dimensional shape of the active site can be altered and decrease the rate of a reaction that
is catalyzed by that enzyme.
C/ If the protein is an enzyme, the 3-dimensional shape of the active site can be altered and increase the rate of a reaction that
is catalyzed by that enzyme.
D/ Only options A and B may be true.
F/Antions A, B and C may be true.
Answer:
A, B and C may be true
Explanation:
The three-dimensional structure (3D) of a protein, also known as tertiary structure, is critical to its function. In general, the 3D protein structure consists of alpha-helix and beta-sheets (secondary structures) associated through disordered coiled-coil regions. Genetic mutations may cause modifications in the 3D protein structure by modifying amino acids that are added to the growing polypeptide chain during the process of translation. In consequence, the relationships among amino acids (i.e., the intermolecular attractive forces that hold them together) may also be altered by these mutations. In general, mutations that generate amino acid changes at the active site of the enzyme will have a deleterious effect, thereby decreasing or inactivating protein function. However, there are situations where a mutation may be beneficial and can eventually increase the rate of reaction of a protein.

Answer: Extensive drinking of water during exercise leads to a condition called hyponatremia.

In snarlymonsters, the number of teeth is polygenic. The recessive condition (aabbcc) results in a toothless snarlymonster, and the dominant condition (AABBCC) results in a snarlymonster with 6 teeth. There are 5 other possible variations. How many teeth would a AaBbCc snarlymonster have
Answer:
The correct answer is - 3 teeth.
Explanation:
It is given that in Snarlymonsters the number of teeth is a polygenic trait and recessive conditions do not form the teeth in the Snarlymonsters which means only dominant alleles are responsible for the teeth.
So, aabbcc = no teeth
AABBCC = 6 teeth
so the number of teeth is the number of dominant alleles present in the SNarlymonster like A, B, C present in offspring.
In the case of the AaBbCc genotype, there are 3 dominant genes A, B, and C, so 3 teeth are present in snarly monsters.
