Answer:
It's MITOSIS.
Explanation: We are also learning about this in class.
During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. Mitosis itself consists of five active steps, or phases: prophase, prometaphase, metaphase, anaphase, and telophase.
In mitosis of the cell cycle, a eukaryotic cell undergo nuclear division followed by cytoplasmic division results form two genetically identical daughter cells. Mitosis It consist of five phases: prophase, prometaphase, metaphase, anaphase, and telophase.
What is mitosis ?The process in which somatic cell undergo equational division where equal number of daughter cell produced from their parent cell.
Here the number of chromosomes remains the same, except in the case of germ cells where the number of chromosomes become half and the nucleus of a cell is divided into two nuclei having equal amount of genetic material.
nuclear division is followed by cytoplasmic division after the separation of the nucleus. It is important for the growth of the cells and the replacement of worn-out cells.

A. Frequent eruptions of large volcanoes.
B. Naturally occurring fluctuations of in the carbon cycle.
C. Utilization of fossil fuels by humans for industrialization.
D. An increase in the sea level due to melting of ice.
Answer:
C. Utilization of fossil fuels by humans for industrialization.
Explanation:
Frequent eruptions of large volcanoes were happening long before humans and will happen after humans too. They are not the reason why we are seeing so much CO2 in the last 200 years.
There are some naturally occurring fluctuations of carbon but not to the degree that we are seeing.
Melting of ice and sea levels rising is due to the global warming problem caused by our dependency on fossil fuels.
glucose enters the epithelial cells of the small intestine against its concentration gradient. select the best explanation from the statements.
The best statement which explains is 'Glucose is co-transported with Na+, which moves down its concentration gradient into the cell'.
It is because the sodium/potassium pump is located in the plasma membrane of the cells.
To transfer the glucose material across the membrane, the Na+/K+ pump utilizes three molecules of ATP to shift potassium ions inside the cell and derives sodium ions outside the cell.
As a result of this, Na ions' concentration increases outside the plasma membrane while the concentration of potassium is higher inside the membrane.
This process is also known as secondary active transport because it drives energy from the primary active transport process.

a transcutaneous pacemaker is most likely an intervention for which dysrhythmia? a. second-degree atrioventricular block, type i b. second-degree atrioventricular block, type ii c. wolff-parkinson-white syndrome d. wandering atrial pacemaker
A transcutaneous pacemaker is most likely an intervention for second-degree atrioventricular block, type ii dysrhythmia.
What is transcutaneous pacemaker?
A temporary method of pacing a patient's heart during a medical emergency is transcutaneous pacing (TCP), often known as external pacing. While some contemporary defibrillators can perform both tasks, transcutaneous pacing and defibrillation use pads and an electrical stimulus to the heart respectively. Defibrillation is used in more serious instances, such as ventricular fibrillation and other shockable rhythms. Electric current pulses are delivered through the patient's chest during transcutaneous pacing to stimulate the heart's contraction.
An unusually slow heart rate is the most typical transcutaneous pacing indication. By definition, bradycardia is a heart rate in an adult patient that is less than 60 beats per minute.

Which one of the following factors does NOT affect Earth’s climate?
A. Ocean Currents
B. Energy from the Sun
C. Elevation
D. Soil Composition
Answer:
D
Explanation:
its just not any other one
Our soil cleans our water, feeds our trees and crops with vital nutrients, and controls numerous significant greenhouse gases in addition to helping to maintain the Earth's temperature. Thus option D is correct.
What is the soil impact on Earth climate?On a smaller scale, soil can also affect climate. More so than drier, looser soils, wetter or denser soils hold heat and stabilize the environment from temperature variations.
In deserts, the temperature can rise by more than 60 °F in a single day. The largest repository for terrestrial carbon is healthy soil. In the carbon cycle, soils are essential because they absorb carbon from decaying plant tissue.
By storing carbon (carbon sequestration) and reducing greenhouse gas emissions in the atmosphere, soils can be effectively managed to mitigate climate change.
Therefore, soil composition factors does NOT alter Earth’s climate.

Genetic and epigenetic changes compound over time to cause cancer. While aging and chronic inflammation are the major causes of epigenetic changes, carcinogenic substances, UV radiation, and other conditions can also cause genetic changes. Our prior exposure levels and life history are reflected in the accumulation and patterns of changes in normal cells. The majority of accumulated changes are regarded as passengers, although they are linked to cancer drivers as they accumulate. Although only hypothesized for genetic changes, this has been demonstrated for aberrant DNA methylation. However, modern technology has made it possible to assess uncommon point mutations, and research has revealed that the rates of their accumulation do actually correspond with cancer risk.

what is active transport?
A. an organisms way of getting materials to its community
B. a cells way of transporting materials that uses energy
C. the nucleus’s way of transporting genetic information
D. when peroxisomes moving materials in a cell
Active transport is a cells way of transporting materials that uses energy.
What is active transport?Active transport is a type of passage through the membrane in which energy is expended for transport to occur. There is a movement of molecules from a region where there is a lower concentration of this molecule to where there is a higher concentration, which is against the concentration gradient.
When overcoming a force, it will need energy to be able to generate this transport, so the transport proteins will need ATP to generate this movement of molecules.
One of the best known molecules that performs this type of transport, and one of the most important in the cell to maintain ion homeostasis inside and outside the cell, is the sodium-potassium ATPase pump, which pumps sodium ions out of the cell and pumps potassium ions into the cell.
Therefore, we can confirm that active transport is a cells way of transporting materials that uses energy.

How many variations do you observe?
Answer:
Variation, in biology, any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation) or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation). Variation may be shown in physical appearance, metabolism, fertility, mode of reproduction, behaviour, learning and mental ability, and other obvious or measurable characters.
chromosomes or by differences in the genes carried by the chromosomes. Eye colour, body form, and disease resistance are genotypic variations. Individuals with multiple sets of chromosomes are called polyploid; many common plants have two or more times the normal number of chromosomes, and new species may arise by this type of variation. A variation cannot be identified as genotypic by observation of the organism; breeding experiments must be performed under controlled environmental conditions to determine whether or not the alteration is inheritable.
Genotypic variations are caused by differences in number or structure of Environmentally caused variations may result from one factor or the combined effects of several factors, such as climate, food supply, and actions of other organisms. Phenotypic variations also include stages in an organism’s life cycle and seasonal variations in an individual. These variations do not involve any hereditary alteration and in general are not transmitted to future generations; consequently, they are not significant in the process of evolution.
