PLZZZZZ HELP!!! WITH 5 STAR THANK AND MARK BRAINLIEST!!! Explain how form and function are related in human cells. Include examples.
Answer:Each cell carries out basic life processes that allow the body to survive. Many human cells are specialized in form and function, as shown in Figure below. Each type of cell in the figure plays a specific role. For example, nerve cells have long projections that help them carry electrical messages to other cells.

Name the type of the leaf when its lamina is entire or when incised?
Answer:
compound
Explanation:
A leaf is said to be simple, when its lamina is entire or when incised, the incisions do not touch the midrib. When the incisions of the lamina reach up to the midrib breaking it into a number of leaflets, the leaf is called compound
Give two examples of phospholipid soluble molecules? How can these molecules move across the cell membrane? What affects the direction of their movement
Answer:
1. Only small uncharged molecules can diffuse freely through phospholipid bilayers (Figure 2.49). Small nonpolar molecules, such as O2 and CO2, are soluble in the lipid bilayer and therefore can readily cross cell membranes. 2. Diffusion through a permeable membrane moves a substance from an area of high concentration (extracellular fluid, in this case) down its concentration gradient (into the cytoplasm). 3. Objects change their motion because unbalanced forces act on them. There are four main factors that affect the motion of objects. These factors are force, friction, inertia, and momentum.
Explanation:
Hope this helps. ^_^
Answer:
Examples include steroids and Vitamins
Phospholipids ,as the name implies fall under the category of lipids. Phospholipids have a hydrophilic "head" which has a strong attraction to water molecules.The hydrophilic head contains a phosphate group which allows for reactivity with water molecules.
Phospholipids also contains two hydrophobic "tails" which has a strong repulsion to water. The tails are derived from fatty acids and are joined by a glycerol molecule. These compounds are less reactive to water molecules .
These properties make phospholipids to be soluble in both water and oil which favors the movement of molecules such as Steroids and Vitamins in and out of the cells through the process called Diffusion.
The direction of movement depends on the concentration of molecules as they usually move from a region of high concentration to a region of lower concentration to ensure there is equilibrium and proper functioning of cells.

What was the Scientific Revolution of the mid-1500s and 1600s? What is the scientific method? List the major steps of the scientific method. What are the lasting consequences of the scientific revolution?
Answer:
Question: What was the Scientific Revolution of the mid-1500s and 1600s?
Answer: Before the mid-1500s and 1600s, Scientists feed on ancient scholars scientific materials and what the church explains through the Bible of how God created the universe and the people that lived in the world. The interest people have to observe their natural environments, coupled with the rise of more educated scientists led to the Scientific Revolution which uses observation of the natural world, experimentation, and a well-followed scientific method to discover the world.
Question: What is the scientific method?
Answer: During the mid-1500s and 1600s scientists developed a method called the scientific method with the aim to lay emphasis on observing the natural world and experimentation to test hypothesis. Making them start thinking like scientists instead of accepting unproven theories.
Question: List the major steps of the scientific method.
Answer:
1. Observation
2. Experimentation
3. Logical Ideas
4. Hypothesis
Question: What are the lasting consequences of the scientific revolution?
Answer:
1. It shaped the way people think and make people question and observe their environments.
2. It embraces the acceptance of proven and tested theories rather than some mystical beliefs.

R. Scientific errors are factors that could have contributed to the uncertainty in the outcome of your experiment. Could measurements have been more accurate? Could you have performed more trials? Could environmental factors, such as the lab's lighting or temperature, have had an effect? State these possible sources of error and analyze or estimate how much they may have affected your results.
Answer:
Yes.
Explanation:
Yes, measurements should be more accurate if these scientific error are removed. Yes, we must perform more trials in order to verify the experiment. Environmental factors, such as the laboratory's lighting or temperature, has a great effect on the experiment and can cause error. In this experiment the errors occur such as instrumental, environmental, procedural, and human. All these error causes inaccurate readings of experiment so greatly affect the experiment.

Answer:
The easiest one to correct would most likely be Class V, since in this type of mutation, the only problem or abnormality is the production of insufficient amounts of the needed CFTR.
Explanation:
Mutation Classes
Class I - Gene contains a stop signal that prevents CFTR from being made.
Class II - CFTR is made, but does not reach the cell membrane
Class III - CFTR is made and in the right place, but does not function normally
Class IV - Channel does not move substances efficiently or at all
Class V - CFTR is made in smaller than normal quantities
the energy required to lift an object is supplied by ATP, which is made by breaking down molecules of
a. carbon dioxide
b. oxygen
c. glycolysis
d. glucose
The energy provided by ATP is driven by the breakdown of glucose molecules. Thus, option D is correct.
ATP or Adenosine triphosphate is the energy molecule that is able to provide energy to the body. Varying pathways and cycles in the cell produce ATP.
Which molecules produce ATP?ATP production is carried out in the degradation of the complex molecules by the cell. The cycle is operated primarily in the cell for the production of ATP in glycolysis.
The ATP is produced in the glycolysis cycle with the breakdown of glucose molecules. Thus, option D is correct.

name and describe the process occurring in the nucleus which results in the formation of an mRNA molecule
Messenger ribonucleic acid (mRNA) is the single-stranded biological molecule that resembles the hereditary sequence of the gene and is needed for coding the proteins molecules essential for cell function and growth.
Transcription is the process that occurs in the nucleus.
What is the process that synthesizes the mRNA?mRNA is the biological molecule that gets formed from the double-stranded DNA molecule by the process of Transcription in the nucleus of the cell.The replicated DNA undergoes a transcription process and it's one strand transcripts to form a single strand of the mRNA molecule with the help of the transcription factors.One of the DNA strands acts as a template for the formation of the pre mRNA molecule with the help of the RNA polymerase II enzyme. The pre molecule formed undergoes an elongation and the termination process and the final mature mRNA is formed.Therefore, transcription results in the formation of the mRNA.
