Which is the MOST accurate statement about cells?
(A) While all organisms have the same total number of cells, the types of cells differ,
(B) Cells are the body's building blocks, the units that make up all organisms.
(C) Cells are identical inside, which equips them to do fundamental things like making copies of themselves.
(D) While animal and plant cells differ because of the cell wall, cells are otherwise the same outside.
The most accurate statement about cells is that they are the body's building
blocks, the units that make up all organisms.
Cells are regarded as the smallest unit of life and the different aggregations
is what forms the tissues, organs and system which make up all organisms.
This is why it is referred to as the building block of all organisms.
Organisms don't possess equal number of cells and all aren't identical as a
result of the various functions each type performs.

How do enzymes act as catalyst to speed up biological reactions
Enzymes are biological catalysts. ... Thus enzymes speed up reactions by lowering activation energy. Many enzymes change shape when substrates bind. This is termed "induced fit", meaning that the precise orientation of the enzyme required for catalytic activity can be induced by the binding of the substrate.on:
Answer:
Chemical reactions occur at the active site of enzymes, where a precise 3D orientation of amino acids is an important feature of catalysis.
Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate.
Activation energy is energy that must be added to get a reaction started, which is recovered as the reaction proceeds.
Enzymes can catalyze reactions through a variety of ways including destabilizing the bonds within the substrate.

The recommended order of draw for a complete blood count, prothrombin time, and cholesterol is:________
Answer:
The use of the word "draw" here refers to the collection of blood samples for laboratory tests.
Step A - The first draw goes into the blood culture bottle or tube with a yellow cover.
Step B - This goes into the coagulation tube with a blue cover.
Step C - The next draw goes into the tube for non-additives. This usually has a red top
Step D - This features collection of blood into the tubes with additives. When dealing with additives, blood samples and additives it is important that the sample and additive is rigorously homogenized. This part can is broken down as follows:
this goes into the SST tube. This tube contains a seperator and a clot activator and is usually is colour coded reddish-gray or gold top.This tube contains Sodium heparin and has a leaf green topThis tube (PST) contains PST contains lithium heparin anticoagulant and a gel separator. It's cover is colour coded light greenThis tube contains Ethylenediaminetetraacetic acid or EDTA for short. It's cover is usually colour coded lavendarThis tube is labelled ACD that is Acid Citrate Dextrose. It's top is coded light yellowthis tube contains Oxalate/Fluoride and it's cover must be colour coded gray.

Plant and animal cells have a cell membrane. That term should be in the center is incorrect in the Venn diagram.
What are the features of Venn diagram?
A Venn diagram is a widely used diagram style that shows the logical relation between sets, popularized by John Venn in the 1880s. The diagrams are used to teach elementary set theory, and to illustrate simple set relationships in probability.
Moreover, a Venn diagram is an illustration that uses circles to show the relationships among things or finite groups of things. Circles that overlap have a commonality while circles that do not overlap do not share those traits.
A Venn diagram uses overlapping circles or other shapes to illustrate the logical relationships between two or more sets of items. Often, they serve to graphically organize things, highlighting how the items are similar and different.

Scientific theories are explanations for naturally occurring events or phenomena. Although scientific theories require extensive observations and experimentation, they can change over time as new evidence is discovered. Scientific laws are principles that are also based on extensive observations and experimentation. Although scientific theories can develop into laws, a theory can only be declared a law if it is proven to be without exception under certain stated conditions. Which of the following is true regarding scientific theories,laws, and knowledge? A. New scientific knowledge is gained by memorizing scientific theories and laws. B. Scientific knowledge must be proven by both scientific theories and laws. C. Scientific theories can lead to scientific knowledge, but scientific theories are not related to scientific knowledge. D. Scientific theories and laws develop from the acquisition of scientific knowledge.
Answer:
C
Explanation:
scientific law is the description of an observed phenomenon. It doesn't explain why the phenomenon exists or what causes it.

Which of the following accurately describes Poiseuille's law?a. blood flow is not related to resistance. b. if resistance increases, flow increases. c. if resistance increases, flow decreases. d. viscosity of the blood is not related to flow. e. pH of the blood influences flow.
Answer: Option C.
if resistance increases, flow decreases.
Explanation:
if resistance increases, flow decreases describe Poiseuille's law because it explain the relationship between fluid flow and the viscosity of the fluid, length and width of the turning. The law describe fluid flow is related to length and radius of tubing and viscosity. Increase in resistance will result in decrease in flow rate because flow and resistance are reciprocally related in one way or the other.

Draw the phases of mitosis of a cell that contains four chromosomes as its diploid or 2n number
Answer:
Please find the diagram attached and explanation below.
Explanation:
Mitosis is a type of cell division that forms two genetically identical cells. It involves four stages viz; prophase, metaphase, anaphase, and telophase.
Considering a diploid (2n) cell with four (4) number of chromosomes.
Prophase- four duplicated chromosomes condense and pair up.
Metaphase- four chromosomes line up at the cell plate or equator in order to get separated.
Anaphase- the sister chromatids are pulled apart by the spindle microtubules
Telophase: the chromosomes recoil and organelles form at opposite poles of the cell.
At the end of cytokinesis, which is division of the cytoplasm, four chromatids are present in each daughter cell. The chromatids becomes individual chromosomes that retain the diploid (2n) chromosome number of four.
Mitosis is a cell cycle division in which the parent cell divides into two daughter cells with alike chromosome numbers.
It consists of four steps namely prophase, metaphase, anaphase and telophase.
According to the question, the diploid (2n) cell with four chromosomes will divide by the following stages. Find the attached image below for the diagram:
Prophase- four copied chromosomes will consolidate and pairing will happen.Metaphase- the joined chromosomes will queue at the middle of the cell plate or equator.Anaphase- the sister chromatids begins stretching apart by the spindle micro tubules near the edge of the poles.Telophase: the chromosomes commence recoiling and other organelles start developing at the corresponding poles of the cell.This was the process of karyokinesis and will be followed by cytokinesis that is the cytoplasm division.
Now the chromatids will become individual chromosomes and two diploids (2n) daughter cells will be formed.
