All organisms come from pre-existing cells that divide.
What is Microscope?Microscope: a device that magnifies small objects, giving the user a close-up view of minuscule structures at a scale suitable for observation and analysis.
Even though optical microscopes are the focus of this article, an image can also be magnified by a variety of different wave types, such as acoustic, X-ray, or electron beams, and is then captured using direct or digital imaging, or a combination of these techniques.
The magnifying power of a microscope is a dimensionless ratio that expresses how often the thing under examination seems to be magnified.
Therefore, All organisms come from pre-existing cells that divide.

What is the role of spindle fibers in mitosis?
Answer:
They help equally devide the cell.
Explanation:
Spindle fibers form a protein structure that divides the genetic material in a cell. The spindle is necessary to equally divide the chromosomes in a parental cell into two daughter cells during both types of nuclear division: mitosis and meiosis. During mitosis, the spindle fibers are called the mitotic spindle.

A person drives her own personal vehicle to work two days of the week. Her commute to and from work is 42 miles a day, and her car averages 28 miles per gallon? How much gasoline
is the person conserving a day if she takes the train instead? (5 points)
O 1.5 gallons per day
O 3.0 gallons per day
O 4.5 gallons per day
0 5.5 gallons per day
Answer:
The correct answer is - 1.5 gallons per day.
Explanation:
Given:
Distance traveled by a person: 42 miles a day
Average of gasoline used - 28 miles/gallon
Solution:
Daily consumption = distance traveled/ average consumption
Placing the value in the formula
= 42/28
= 1.5
Thus, the correct answer is - 1.5 gallons per day conserved.

The absorption process in the kidneys depends on the ___ between the medulla and the filtrate.
Answer:
try b and tell me if i am wrong please
Explanation:
The absorption process in the kidneys depends on the between the medulla and the filtrate in the cortex as the cortex is found in between the medulla and filtrate.
The cortex presents an area for arterioles and venules from the renal artery and vein, in addition to the glomerular capillaries, to perfuse the nephrons of the kidney. Erythropoietin, a hormone important for the synthesis of the latest crimson blood cells, is likewise produced withinside the renal cortex. Its predominant feature is to reabsorb water and sodium chloride from the filtrate.
What is the function of coetex ?This conserves water for the organism, generating exceedingly focused urine: The inner-maximum location of the kidney is organized into pyramid-like structures, that include the majority of the nephron structure. renal cortex: The outer location of the kidney, among the renal tablet and the renal medulla, includes an area that consists of blood vessels that hook up with the nephrons.
Thus it is clear that the absorption process in the kidneys depends on the cortex that is in between the medulla and the filtrate.

Suppose that a cytoplasmic protein (a protein that will function in the cytoplasm inside of the cell) is synthesized by a particular cell type. Describe the route that this protein will take from the moment its synthesis starts in the nucleus until it makes it into the cytoplasm.
Answer:
A specific gene that contains the information to encode the target protein is transcribed as a primary transcript (pre-mRNA). Subsequently, the pre-mRNA is processed to form a mature mRNA. Finally, this mRNA then moves through a nuclear pore from the nucleus to the cytoplasm where proteins are translated in the ribosomes
Explanation:
The cell nucleus contains the majority of the cell's genetic material localized on linear molecules called chromosomes. During transcription, genes (specific chromosome segments) are used to synthesize primary transcripts (pre-mRNAs) which are then proceeded to produce mature messenger RNAs (mRNAs). RNA processing involves the removal of non-coding intron regions and the joining of coding exon regions (RNA splicing) in order to form a mature mRNA sequence. Subsequently, the mature mRNA leaves the nucleus through the nuclear pores of the nuclear membrane and travels to the ribosomes where is decoded (translated) to produce a specific polypeptide chain (i.e., a protein). Within the ribosome, the mRNA strand binds to multiple transfer ribonucleic acids (tRNAs) via complementary and consecutive three-nucleotide mRNA sequences called triplets or codons, and tRNAs deliver specific amino acids that are consecutively added to the polypeptide chain.

What process occurs at the boundary between the capillaries and the alveoli?
A.
Nitrogen enters the alveoli, and oxygen enters the capillaries.
B.
Oxygen enters the alveoli, and carbon dioxide enters the capillaries.
C.
Oxygen enters the alveoli, and nitrogen enters the capillaries.
D.
Carbon dioxide enters the alveoli, and oxygen enters the capillaries.
Answer: D. Carbon dioxide enters the alveoli, and oxygen enters the capillaries.
Explanation:
This describes the exchange of gases in the lungs. When blood from the rest of the body gets to the lungs through the capillaries, oxygen flows from the alveoli which are tiny air sacs in the lungs, into the blood in the capillaries.
Carbon dioxide from the blood brought to the lungs will then flow into the alveoli which will then expel it through the nose. This repeated process ensures that the body keeps getting oxygen and expelling carbon dioxide.

what are two ways in which white blood cells fight pathogens that have entered the body?
A)They produce Antibodies that work against the pathogens
B)They produce hormones to locate the pathogens
C)They surround and destroy the pathogens
D)They make digestive acids to destroy the pathogens
Answer:
A and C
Explanation:
I'm pretty sure that's the right answers. Hope this helps! <3
The two ways in which white blood cells fight pathogens that have entered the body are "they produce antibodies that work against the pathogens and they surround and destroy the pathogens".
What are pathogens?Any organism as well as an agent that could cause the disease would be a pathogen in the widest and oldest sense.
What are antibodies?Whenever the immune system of the body recognizes dangerous compounds, known as antibodies, it produces a protein designated an antibody.
Therefore, the two ways in which white blood cells fight pathogens that have entered the body are "they produce antibodies that work against the pathogens and they surround and destroy the pathogens".
Hence, the correct answer will be options (A) and (C).

What is another term for the responding variable?
O primary variable
dependent variable
independent variable
uncontrolled variable
The answer is DEPENDENT VARIABLE
-edgy 2021
Answer:
B. Dependent variable.
Explanation:
An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
Hence, an experiment is used by scientists or psychologists to illustrate how a change in variable affects behavior.
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
In an experiment, there are two (2) main types of variables and these are;
I. Independent variable: this is the variable that is being manipulated or alters and as such it is the cause of a behavior. This variable stands alone.
II. Dependent variable: this variable is the direct effect of the actions of the researcher in an experiment.
Basically, the dependent variable is the variable that is being measured and tested by an experimentalist.
Hence, dependent variable is another term for the responding variable because it responds to an action.
