Answer:
A cancerous tumor will form in the thyroid
Explanation:
Cyclin-dependent kinases are proteinous in nature. They perform z series of biological activities in the body. They are responsible for controlling the cycle of a cell.
Cyclin-dependent kinases when they are mutated can cause the cells present in the human body to begin to multiply and divide uncontrollably thereby resulting in the formation of cancerous cells in the body.
This is why when a researcher repeatedly injects a mouse with a variety of cyclin-dependent kinases, including mitosis-promoting factor (MPF) and they are delivered to the thyroid gland by carrier complex in the blood, the cells in the thyroid would start to multiply uncontrollably thereby causing a cancerous tumor to be formed in the thyroid.

Answer:
He concluded that all cells come from preexisting cells.
Explanation:
Rudolf Virchow while building on the work of Theodore Schwann formulated a part of the cell theory which opined that cells arose from pre-exsiting cells which disproved the theory of spontaneous generation
Although this assertion has earlier been made by another scientist, Robert Remak in 1852, Schwann did not accept until later until after series of investigations. Schwann was later accused of publishing the work of Robert Remak as his in 1855.
The other parts of the cell theory include:
All living organisms are made up of cells which could be prokaryotic or eukaryoticCells are the basic unit of life.Answer: Rudolf Virchow's concluded that all cells come from preexisting cells.
Explanation: Rudolph Virchow state that 'Omnis cellula e cellula' which means that every cells arise from preexisting cells. Until Virchow came out with this theory, it was believed that new cells were created from a fluid called blastema ( it was believed that the imbalance caused disease).
Rudolf Virchow's lay the ground work on cellular pathology ( that is the study of disease at the cellular level). His work made it more clear that diseases occur at the cellular level and not blastema as believed. Diseases were diagnosed more accurately by scientist due to Rudolf Virchow's work.
What must this cell do before it can carry out mitosis? (The cell has a diploid number of 444 chromosomes; 2n = 42n=42, n, equals, 4)
Answer:
grow its cell contents, double its DNA and synthesize proteins
Explanation:
Before a cell can carry out mitosis, such cell will need to grow and develop its contents, synthesize (double) DNA, and also synthesize proteins.
Mitosis involves the equational division of non-sex cells to give two daughter cells. Hence, the contents of a cell that wants to divide by mitosis must be enough to be shared by the two daughter cells.
This is why a cell that will divide by mitosis has to go through the G1 phase, the S phase and the G2 phase where the content of the cells grow and develops, DNA of the cell is replicated, and protein is synthesized respectively. All these processes take place during the interpphase stage of the cell cycle.
Final answer:
Before mitosis, a cell with a diploid number of 4 must replicate its DNA during interphase to ensure each daughter cell receives an identical set of chromosomes.
Explanation:
Before a cell can carry out mitosis, it must first undergo interphase, specifically the S phase (synthesis phase), where the cell replicates its DNA. During interphase, the cell's chromosomes are dispersed as structures in the nucleus and must be duplicated to ensure that each of the two resulting daughter cells receives an identical set of chromosomes. The process of DNA replication is crucial because chromosomes contain genes, which must be accurately distributed to maintain the organism's genetic information. Therefore, when an animal cell with a diploid number of four (2n = 4) undergoes mitosis, it produces two diploid daughter cells each with four chromosomes.

Whereas superficial flexors in the anterior compartment of the forearm originate from the _____ epicondyle of the humerus, the superficial extensors in the posterior compartment of the forearm originate from the _____ epicondyle of the humerus.
Answer:
Whereas superficial flexors in the anterior compartment of the forearm originate from the medial epicondyle of the humerus, the superficial extensors in the posterior compartment of the forearm originate from the lateral epicondyle of the humerus.
Explanation:
The forearm has 2 compartments: an anterior compartment responsible for the flexion of the wrist, and a posterior compartment with the function to extend the wrist.
The superficial muscles in the anterior compartment arise from the common flexor tendon that originates from the medial epicondyle of the humerus. This compartment is mostly innervated by the median nerve.
The superficial muscles in the posterior compartment originate from the lateral epicondyle of the humerus and are innervated by the radial nerve.
The ulnar nerve innervates the flexor carpi ulnaris and flexor digitorum profundus in the forearm.

What evidence is there that every organism on earth once had a common ancestor
There is a tonne of evidence that points to a common ancestor for all living things on Earth. Numerous sources, including as genetic, morphological, and fossil data, contribute to this proof. First, the genomic data points to a common ancestor for all living things on Earth.
What is the depiction regarding the DNA ?DNA is a component of all living things, and all living things' DNA is made up of the same four nucleotide bases: adenine, guanine, cytosine, and thymine.
The same genetic code, which is a collection of instructions that governs how the data in DNA is utilised to make proteins, is also used by all living things. This shows that all living things had a common ancestor who had the same four nucleotide bases and genetic code.
Second, the data from morphology implies believe there is a single ancestor for all living things on Earth. There are some traits that all species have, such a cell membrane and a nucleus.
Additionally, the same fundamental building ingredients found in proteins, carbohydrates, and lipids make up every single life. This argues that all living things descended from an ancestor who had the same fundamental traits and building components.
Last but not least, fossil evidence points to a common progenitor for all living things on Earth. Direct proof of an organism's evolutionary history can be found in fossils. Scientists have been able to track the evolutionary history of creatures by analysing the fossil record, and they have found that all organisms have developed from a common ancestor. Consequently, there is a lot of data that supports the evidences.

Why are enzymes needed during DNA replication?
Answer:
An enzyme is a molecule that speeds up a reaction. In the case of DNA reproduction, enzymes not only speed up the reaction, they are necessary for DNA reproduction.
Explanation:
An enzyme is a molecule that speeds up a reaction. In the case of DNA reproduction, enzymes not only speed up the reaction, they are necessary for DNA reproduction.
Recall that DNA is a long strand with a many repeating base pairs. In order for DNA to reproduce, the base pairs must be split apart. One half of the strand is then used as a template to build a new strand of DNA.
The enzyme helicase is responsible for splitting DNA along the base pairs. Helicase moves along the DNA strand unzipping the strand just as a zipper.

Which of the following characteristics is (are) possessed in common by true mosses, ferns, and spike mosses, and therefore becomes useless at helping to determine to which of these groups flower of stone belongs? 1. a sporophyte generation that is dominant 2. true leaves and roots 3. flagellated sperm 4. alternation of generations
Final answer:
True mosses, ferns, and spike mosses possess alternation of generations in common, which becomes useless for determining the flower of stone's group. Other characteristics they share include the presence of a sporophyte generation that is dominant.
Explanation:
Mosses, ferns, and spike mosses share the presence of alternation of generations, which is the cycle of having a haploid gametophyte stage and a diploid sporophyte stage in their life cycles. The sporophyte generation is dominant in these plants, meaning it is the more visible and longer-lived stage.
In terms of the other characteristics listed, true mosses, ferns, and spike mosses differ. True mosses have simple midrib-like structures resembling true leaves, while ferns have fronds and spike mosses have strap-like leaves. True mosses and spike mosses have flagellated sperm, while ferns do not. Additionally, true mosses and spike mosses lack true roots, instead having multicellular rhizoids, while ferns have true roots and leaves.

in which replication cycle is the viral genome reproduced without damage to the host cell
Answer:
lysogenic cycle
Explanation:
it allows a phage to reproduce without killing its host. Some phages can only use the lytic cycle, but the phage we are following, lambda ( λ), can switch between the two cycles.
The viral genome can be reproduced without harming the host cell during the lysogenic cycle. Here the viral genome becomes part of the host's DNA, and is replicated without causing cell death.
Explanation:The viral replication cycle in which the viral genome is reproduced without causing damage to the host cell is known as the lysogenic cycle. In this cycle, the viral genome is incorporated into the host DNA and is replicated along with the host cell’s DNA without causing cell death. This is in contrast to the lytic cycle where the virus destroys the host cell to release new virus particles. The lysogenic cycle allows the virus to lay dormant within the host cell, potentially for many years.

:denser regions with little space between atoms
:same age stars
The material from the collapsing of parts of a gas cloud will first form clumps ; ( B ) In denser regions with little space between atoms
Since the inner cores of a gas cloud is denser ( i.e. little or no space between the atoms present in the inner cores of the gas cloud ). when a gas cloud starts collapsing the denser region of the gas cloud will collapse first into small fragments known as clumps.
The clumps formed during the collapsing of the inner core of the gas cloud will come together to form what is known as protostars after a very long period.
Hence we can conclude that the material from the collapsing of parts of a gas cloud will first form clumps In denser regions with little space between atoms.

A plant has two alleles for color the red allele is recessive and is represented by q the purple allele is dominant and is represented by p if 76 of 100 organisms are red what is q
Answer:
0.87Explanation:
As given
q=red (recessive)
p=purple (dominant);
According to Hardy-Weinberg law;
(p+q)= 1 = p²+ 2pq+ q²
As the information provided, the red allele is recessive and it is represented by q
so q²= 76/100 = 0.76
Now we can find the recessive allele frequency using it as q is the frequency of recessive allele.
Thus, q= √0.76
q= 0.8717797887
Thus, the value of q is 0.871
