Following are the solution to this question:
Explanation:
In a spindle in prophetic (mitotic apparatus) spindle, pulley and cellular membranes form at the kinetochore of metaphase genes intended besides separation of anaphase daughter chromosomes.
Even though the cycle of creation of the cells move towards opposite poles, microtubules gradually form a network between them, and its duplicate chromosomes would be later removed.
Why do you think prokaryotic cells do not have all the organelles that eukaryotic cells do? What does this tell you about prokaryotic cells?
Answer:
Explanation:
A prokaryotic cell is a type of cell that does not have a true nucleus or membrane-bound organelles. Organisms within the domains Bacteria and Archaea are based on the prokaryotic cell, while all other forms of life are eukaryotic
A prokaryotic is a primitive cell that lacks organelles, unlike the eukaryotic cells, and are simple organisms.
What are prokaryotes?Prokaryotes are organisms that are simple and evolved before the complex eukaryote. They include bacteria and archaea that are simple and lack organelles that are found in eukaryotes.
They do not have a nucleus and rather have their genetic material disposed of as nucleoids in the center of the cell that undergoes the simple process of the central dogma.
The simple cellular processes and reproductive methods are the reason they lack many organelles. This tells that prokaryotes are simple and primitive types of cells.
Therefore, prokaryotes lack a distinct nucleus.

Describe what happens in the ocean with plate tectonics
Answer:
As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. ...

A structure that looks the same and does the same job but was not present in a common ancestor is termed:______.
Answer:
The correct answer is - analogous.
Explanation:
Analogous structures or organs are the structures with the same look which is developed to perform the same job and not present because inherited by a common ancestor.
These structures are present in unrelated organisms and look the same from outside and perform the same action for example wings of bat and birds look and perform the same action but not inherited from a common ancestor.

Type 1 diabetes is caused by destruction of beta cells in the pancreas that produce insulin. Which of the following best explains why a person with this disease needs medication?
a. Medication is needed to act as a signaling molecule to activate the signal transduction pathway.
b. Medication is needed to allow alternate signaling transduction pathways to control glucose levels.
c. Medication is needed to open channels to allow signaling molecules to enter pancreatic cells.
d. Medication is needed to serve as second messengers to regulate glucose uptake by cells.
Answer:
the answer is a. Medication is needed to act as a signaling molecule to activate the signal transduction pathway.
i took the quiz
Medication is needed to act as a signaling molecule to activate the signal transduction pathway. So, the correct option is (A).
What is Type 1 Diabetes?Type 1 diabetes also called insulin-dependent or juvenile diabetes which is usually develops in children, adolescents, and young adults, but it can occur at any age. A condition in which the immune system destroys the insulin-producing cells in the pancreas. These are called beta cells.
There are several signs of type 1 Diabetes which include:
Extreme thirstIncreased hungerDry mouthUpset stomach and vomitingFrequent urinationWhen a person suffering from this disease needs medication which is need to act as signaling molecule to activate the signal transduction pathway. Type 1 Diabetes is characterized by a progressive loss of insulin-producing β-cells in the islets of the pancreas. Immune destruction of β-cells is partly mediated by high levels of pro-inflammatory cytokines.
Thus, medication is needed to act as a signaling molecule to activate the signal transduction pathway. So, the correct option is (A).

Human protein X is encoded by human gene X. Gene X consists of 4 exons of 200 bp each, interspersed with introns of 1,000 bp each.
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.
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.

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.

Answer:
it would not allow enolase to perform properly because it will bind to it and change its shape not allowing 2-phosphoglycerate to bind to it and convert to phosphoenolpyruvate. this is because it is non-competitive which means there is no way that the molecule could bind to the enzyme.
