Describe the events that occur during the cell cycle. Include what happens in each of the following stages: interphase, mitosis, cytokinesis.
Answers
Answer:
Cell cycle or cell division refers to the series of events that take place in a cell leading to its maturity and subsequent division. These events include duplication of its genome and synthesis of the cell organelles followed by division of the cytoplasm.
interphase-During interphase, the cell copies its DNA in preparation for mitosis. Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, reads its DNA, and conducts other "normal" cell functions. This phase was formerly called the resting phase.
mitosis-In cell biology, mitosis is a part of the cell cycle, in which, replicated chromosomes are separated into two new nuclei. Cell division gives rise to genetically identical cells in which the total number of chromosomes is maintained.
Cytokinesis-Cytokinesis is the division of the cytoplasm in eukaryotic cells that produces distinct daughter cells. Cytokinesis occurs at the end of the cell cycle following mitosis or meiosis. In animal cell division, cytokinesis occurs when a contractile ring of microfilaments forms a cleavage furrow that pinches the cell membrane in half.

many
B. Robins and sparrows have different types of bases.
C. Robins and sparrows have different arrangements of the bases.
D. Robins and sparrows have the same arrangement of the bases.
Answers
Answer: the answer is C —> AP.EX
Explanation:
The nucleotide bases are the nitrogenous rings that form the backbone of the nucleic acid. Robins and sparrows have the same bases with different arrangements. Thus, option C is correct.
What are nucleotide bases?The nucleotide bases or the nucleobases are the fundamental units that together with the sugar molecule and phosphate make the structure of the DNA or RNA.
There is a total of five nucleotide bases divided into purines and pyrimidines based on their ring structures. The purine consists of adenine and guanine, pyrimidine of cytosine, uracil, and thymine.
The bases are universal in organism containing the DNA or RNA but only differs in their arrangements that result in the development of the various traits and characteristics of the organism.
Therefore, in option C. the bases are arranged differently in species.

In studying the environment, nature does the experiments, scientists collect the data. How does the principle of uniformitarianism help answer questions about environmental changes?
Answers
Answer:
The principle of uniformitarianism helps answer questions about environmental changes because it gives scientists the idea that the scientific conditions that exist today have always been in existence. This makes it easier to draw correlations.
Explanation:
The principle of uniformitarianism states that the natural conditions that exist today have remained unchanged through the span of human life. This helps scientists in their understanding of nature. For example, they are better able to understand the formation of the earth as well as the uniformity of law across space and time.
Uniformity of law is an aspect of the principle of uniformitarianism which states that the laws of nature are constant across time and space. Uniformity of degree states that geological conditions have remained constant over time. These principles help scientists to better understand environmental changes.

Answers
Answer:
Water separates polar molecules from each other by forming hydrogen bonds.
Explanation:
A polar molecule is a molecule in which the distribution of electrons between the covalently bonded atoms is not even. This means that one end of the bond is slightly more positively charged, while the other end is slightly more negatively charged.
An example of a polar molecule is a molecule of water (H2O). Substances with similar chemical characteristics dissolve in each other. This means that polar molecules will dissolve in water. The partially negative part of a water molecule will interact with the partially positive part of another polar molecule. This results in the formation of hydrogen bonds, which occur when a hydrogen atom is located between a pair of other atoms that have a high affinity for electrons.

The concentration of a substance inside a cell is greater than outside the cell. What type of transport is needed to move molecules of the substance from outside the cell to inside?
Answers
Answer:
Osmosis
Explanation:
The type of transport needed to move molecules of the substance from outside the cell to inside is active transport.
What is active transport?Active transport is the movement of molecules against a gradient or other form of resistance, for example from a lower to higher charge area.
Cells use active transport to accumulate molecules such as glucose and amino acids.
A cell must use energy to move compounds against such a concentration or electrochemical gradient.
Active transport mechanisms do exactly that, expending energy more often in the form of ATP to maintain proper ion and molecule concentrations in living cells.
In the given scenario, the concentration of substance is more inside the cell than outside and the substance has to move from outside to inside the cell. This requires energy for processing.
Thus, the given scenario can be accomplished using active transport.

What are celestial bodies?A celestial object is an observable cosmic phenomenon that happens naturally. The terms "object" and "body" are frequently used synonymously in astronomy.
A celestial object, on the other hand, is a complex, less cohesively bonded structure that could include numerous bodies or even other objects with substructures, as opposed to a celestial body, which is a single, tightly bound, adjoining entity. Space objects like the Sun, planets, moons, and stars are referred to as celestial bodies or heavenly groups.
They are normally quite far away from us and are a part of the vast cosmos we inhabit. Such objects are scattered throughout the majestic night sky, and when viewed through a telescope, they reveal intriguing worlds of their own.
Therefore, Mercury, Mars, Venus, Earth, Neptune, Uranus, Saturn, and Jupiter Is smallest to largest.

What if researchers followed a similar method used in this activity to calculate the correlation coefficients for the gene expression patterns of every patient with osteosarcoma and they found that all patients fell into two categories of gene expression patterns? What would this tell you about the single disease we call osteosarcoma? How might this information affect osteosarcoma cancer patient diagnosis and treatment in the future?
Answers
Answer:
- Abnormal gene expression patterns can lead to osteosarcoma
- Different signaling pathways (at least two) are involved in osteosarcoma
- Differentially expressed genes might be promising biomarkers for early detection of osteosarcoma
Explanation:
Cancer can be defined as a group of genetic diseases that are characterized by uncontrolled/inappropriate cell growth. In general, cancer pathways are associated with abnormal expression of signaling components that disrupt the regulatory networks capable of controlling cell function, thereby cancerous cells can inhibit programmed death cell (apoptosis). Osteosarcoma is one type of cancer disease that starts in the bones, i.e., this disease may be triggered by overactivity of bone cells. Additionally, it is important to note that different immune-related genes were recently found to be dysregulated in osteosarcoma. For example, differentially expressed immune-related genes involved in PI3K/AKT, MAPK and JAK-STAT signaling pathways have shown prognostic value in this disease.
Abnormal gene expression patterns can lead to osteosarcoma, different signalling pathways are involved in osteosarcoma, and differentially expressed genes might be promising biomarkers for the early detection of osteosarcoma.
What is the cause of osteosarcoma?Most osteosarcomas are not caused by inherited gene modifications, but instead are the effect of gene changes acquired during the individual lifetime.
Sometimes these gene modifications are caused by radiation therapy used to treat another form of cancer because radiation can harm the DNA inside cells.
Thus, these are the following reasons.
