Answer:
The amount of bacteria that are there at the end of 55 hours is 2310231000
Explanation:
From the description in the question, the bacteria's population size doubles per hour;
Within 1 hour = 21002100 × 2 = 42004200
Thus
After 1 hr ⇒ 42004200
55 hrs ⇒ ?
? = 55 × 42004200 = 2310231000
The amount of bacteria that are there at the end of 55 hours is 2310231000

The cryosphere and the geosphere are two biospheres which destructs the rock.
What is cryosphere?The cryosphere is the region of the Earth's climate system that contains seasonally frozen ground, solid precipitation, snow, sea ice, lake and river ice, icebergs, glaciers, and ice caps. The name "cryosphere" derives from the Greek word "kryos," which means frost or ice cold.
A non-profit, international scientific magazine called The Cryosphere (TC) is devoted to publishing and discussing research papers, brief communications, and review articles on all facets of frozen ground and water on Earth and other planetary bodies.
Ice sheets and glaciers, planetary ice bodies river and lake ice, seasonal snow cover, sea ice, inner sensing, numerical modeling, in situ and laboratory studies.
Therefore, The cryosphere and the geosphere are two biospheres which erodes the rock.

Formed when caves can no longer support the dirt above it.
Answer:
Collapse dolines.
Explanation:
A doline is a special type of geological depression characteristic of karst reliefs. These reliefs are formed by the chemical weathering of rocks made of minerals that are soluble in water. In general, dolines are found in places where rocks are composed of limestone and clay in different proportions. When the calcium carbonate of limestone gets in contact with the rainwater, turns into calcium bicarbonate, which is soluble in the presence of water. Clay then deposits in lower areas originating the dolines or depressions.
Dolines might be formed by dissolution (the soil is dissolved in pluvial water that first flood and then infiltrate) or by collapsing. Collapse dolines occur because first, soluble material in lower layers formes a cavity underground. Soluble material flow to lower areas making a place to a cavity or hole under the ground. It gets bigger with time as the material in the bottom keeps being removed. It reaches a point in which the cave can no longer support the roof material, such as rocks, soil, and vegetables, and ends collapsing.

Two genes interact to produce various phenotypic ratios among F2 progeny of a dihybrid cross. Design a different pathway explaining each of the F2 ratios below, using hypothetical genes R and T and assuming that the dominant allele at each locus catalyzes a different reaction or performs an action leading to pigment production. The recessive allele at each locus is null (loss-of-function). Begin each pathway with a colorless precursor that produces a white or albino phenotype if it is unmodified. The ratios are for F2 progeny produced by crossing wild-type F1 organisms with the genotype RrTt. Which statement is correct? 12/16 white: 3/16 green: 1/16 yellowA) At least one copy of both dominant alleles results in white; at least one copy of one of the dominant alleles also results in white, but at least one copy of the other dominant allele produces green; and the absence of either dominant allele produces yellow.B) If both dominant alleles are present, the result is green. At least one copy of one specific dominant allele is required for yellow. If that dominant allele is not present, the result is white, regardless of whether the other dominant allele is present.C) At least one copy of each dominant allele results in white, at least one copy of either dominant allele produces green, and the absence of either dominant allele produces yellow.

Digestion of an unlabeled carbohydrate results in increased amounts of the monosaccharides glucose and galactose. Which is most likely to be the original, unlabeled carbohydrate?
Answer:
lactose
Explanation:
Lactose is a disaccharide sugar made up of glucose and galactose monosaccharide subunits. In lactose, galactose and glucose molecules form a covalent glycosidic bond denoted as an (β-1→4) glycosidic bond. Lactase is an enzyme that hydrolyzes lactose into glucose and galactose, which can be then absorbed into the bloodstream by the cells lining the small intestine. In an alkaline solution, lactose may also isomerize to generate a mixture of lactulose (20-30%) and lactose (70-80%).

Melanin is a that is produced in organelles called in specialized cells called ________.
Answer:
Melanocytes
Explanation:
Melanocytes produce the protective skin-darkening pigment melanin. Melanocyte, specialized skin cell that produces the protective skin-darkening pigment melanin. Birds and mammals possess these pigment cells, which are found mainly in the epidermis, though they occur elsewhere like in the matrix of the hair.
Melanin is a that is produced in organelles called in specialized cells called
MelanosomesMelanin is a dark pigment that is found in the skin of a human. This factor affects the color of the eyes, hair, etc in people as the more melanin available in the body, the darker these parts of the body are.
A specialized cell is responsible for the production of melanin called melanosomes and this is in varying quantities in different people.
Melanosomes are those cell nucleus that are responsible for the production, storage and transfer of melanin to the parts of the body.
Therefore, the correct answer is melanosomes

Which mutation below would result in the greatest amount of change in the proteins that code for a particular trait?
(Please help I will reward)
A. inserting three nucleotides
B. deleting three nucleotides
C. deleting one codon
D. deleting two nucleotides
Answer:
Mutations are errors in codons caused by changes in nucleotide bases. Some mutations may not have much effect. For example, if the codon GAA becomes the codon GAG, because the genetic code is degenerate, the codon will still code for the amino acid glutamate. Such ineffectual mutations are called silent mutations. Some mutations, however, can have a huge affect on coding for amino acids, which can in turn affect what proteins are produced, which can have a profound effect on cellular and organismal function.

An mRNA cap will be found on ____________.
a. the primary transcript
b. the mRNA
c. at least one of the lariats
d. the poly(A) tail.
e. exon 1
f. all exons
g. some introns
Answer:
a. the primary transcript
Explanation:
The first step in RNAm maturation is the modification of the 5' end of the transcript via the addition of a structure called a cap or 7-methyl guanosine cap. The enzymes responsible for the formation of this cap are recruited to the phosphorylated C-terminal domain after the addition of the first twenty to thirty nucleotides of ARN. The formation of the cap is started by the addition of a GTP molecule oriented inversely to the 5' end nucleotide on RNA. Then methyl groups are added to this G residue and to the ribose forms of one or two nucleotides located on the 5' end. All these reactions take place in the nucleus when the mRNA is found as a primary transcript.
A man has extra digits (six fingers on each hand and six toes on each foot). His wife and their daughter have the normal number of digits (five fingers on each hand and five toes on each foot.) The couple's second child has extra digits. What is the probability that their next (third) child will have extra digits?a. 9/16.
b. 3/4.
c. 1/16.
d. 1/2.
e. 1/8.
Answer:
The correct answer is - option D. 1/2
Explanation:
Extra digits on hands and feet mean an individual has six fingers in each hand and feet, this is known as polydactyly. Polydactyly shows an autosomal dominant type of inheritance pattern.
In this case, the mother is normal so she must be recessive alleles and the first daughter is normal so the father must have a recessive allele which means he is heterozygous.
