Answer:
Explanation:
"how can you account for the great number, size, and complexity of organic compounds? carbon can bond with so many elements. It can bond with itself and form long chains. Also, all macromoleculse are composed of C,H,N, and O."
Organic compounds number in the millions, far outnumbering inorganic compounds. The reason for this is due to the uniqueness of carbon's structure and bonding abilities.
What are organic compounds?Any of a wide range of chemical compounds in which one or more carbon atoms are covalently linked to atoms of other elements, most commonly hydrogen, oxygen, or nitrogen.
Carbides, carbonates, and cyanides are among the few carbon-containing compounds that are not classified as organic.
Organic compounds in the body include carbohydrates, lipids (including phospholipids), proteins, nucleotides, and nucleic acids.
Water (H2O), bimolecular oxygen (O2), carbon dioxide (CO2), and some acids, bases, and salts are the most important inorganic compounds. The human body is 60-75% water.
Organic compounds outnumber inorganic compounds by orders of magnitude. This is because of the uniqueness of carbon's structure and bonding abilities.
Thus, this way, one can account for the great number, size, and complexity of organic compounds.

What is the function of the nucleus of a cell.
Answer:it coordinates cell activities like protein synthesis and cell division. Anatomically the nucleus is made up of several components: nuclear envelope, nuclear lamina, nucleolus, chromosomes, nucleoplasm are some of these components.
Explanation:
Answer:
The nucleus controls and regulates the activities of the cell and carries the genes, structures that contain the hereditary information. Nucleoli are small bodies often seen within the nucleus. The gel-like matrix in which the nuclear components are suspended is the nucleoplasm.

Can some please write this for me?I really dont care what the reason are I just need it done
Answer:
I will work my hardest. Thank you for considering me.
Explanation:
The reason for my application is I want to help people with their learning and increase their knowledge. I made this because I was inspired by a woman I knew who wanted to make the world a way better place than it is now. I want to follow in that same woman's footsteps. I love helping people also. It gives me a great feeling to know that, that same person that I just helped will remember what I did for them for a short time. I'm sure they'll understand a little bit more at least. I want people to understand their work and how to get it done without having to take a guess, second guess themselves, or get the entire answer wrong. It hurts their grade and their heart. Sometimes my heart too. So, in conclusion I created my application for people to get help on what they do not understand. Maybe, just maybe, after they try my application, they'll understand way better.
I really hope I did the right thing. Tell me if I didn't. I'm really sorry if I didn't I tried my best. I hope it helps you if I did do the right thing! :)

The diffusion of water molecules in and out of cells is very common.
Which of the following is the process by which water moves across a
membrane, from an area of high concentration to low concentration,
without the use of energy? *
osmosis
hydrolysis
photosynthesis
cyclosis
Osmosis is the process; it is essentially diffusion, which is a spontaneous (no energy input required) process as applied to water.
----------------------------
Hydrolysis is incorrect; that describes a type of chemical reaction in which water breaks a chemical bond.
Photosynthesis is incorrect; that describes the complex process in which energy in light is converted into chemical energy.
Cyclosis is incorrect; that describes the movement of cytoplasm within a cell. There is no spontaneous, net movement of water across a concentration gradient.
Why is a cell membrane so important
Answer:
-provides protection for a cell
-provides a fixed environment inside the cell.
-The cell membrane also provides some structural support for a cell.
Explanation:
Answer: The cell membrane is very important because it provides mainly all the protection over the cells. It’s flexibility also helps a LOT!
Which of the following best explains why a cell's plasma membrane is composed of two layers of phospholipids rather than just a single layer?
Answer: The hydrophilic tails are directed inward and the hydrophobic heads are directed outwards.
Explanation:
A phospholipid is made up of two ends a hydrophilic or water-loving end that is phosphate head and a hydrophobic tail that is made up of fatty acid tail. The arrangement of phospholipid in a bilayer structure allows the entry of oxygen, carbon dioxide, and lipids to pass through them via concentration gradient via simple diffusion.
Lipids are amphipathic molecules that compose the membrane. Membrane lipidic bilayers allow only the hydrophilic heads to interact with water inside and outside the cell, while hydrophobic tails remain in the interlayer space, away from water.
----------------------------------------------
Two lipidic layers compose the cell membrane. There are also proteins and glucans incrusted in between.
Since lipids are amphipathic molecules with hydrophilic heads -negatively charged phosphate group- and hydrophobic tails, they need to form two opposite layers.
Lipids are arranged with their hydrophilic polar heads facing the exterior and the interior of the cells in contact with water. Meanwhile, their hydrophobic tails are against each other, constituting the internal part of the membrane.
Membranes are fluid, meaning that lipids and proteins composing them can move laterally, transversally, or rotationally.

1. Krista is conducting an investigation to determine how much fertilizer is best for her sunflower plants. She uses five plants and gives each a different amount of water for six weeks. Each week, she measures the height of each plant. She records her findings in a chart.
Answer the following:
1a. What are the independent and dependent variables?
1b. What should she record in the chart?
1c. What kind of scientific investigation is this example?
Answer:
1a. Independent variable: WATER
Dependent variable: HEIGHT
1b. the height of each plant every week
1c. Experimental investigation
Explanation:
The independent variable in an experiment is the variable that is changed or manipulated by the experimenter. In this case, the independent variable is the AMOUNT OF WATER given to each plant.
Dependent variable is the variable that is measured in an experiment. It is the variable that responds to changes made to the independent variable. In this experiment, the dependent variable is HEIGHT.
(1b) In an experiment, the dependent variable is the variable that is recorded. Hence, in this experiment, the HEIGHT of each plant every week is recorded in the chart.
1c) 1c. This investigation is a type of EXPERIMENTAL INVESTIGATION because it involves testing how the independent variable affects the dependent variable.

Explanation:
Which of the following best represents a function of a lipid within an organism? O Lipids are components of cell membranes All the answer choices are correct O Lipids are parts of proteins O Lipids form a large part of the helical DNA structure
Answer:
The statement that best represents a function of lipids within an organism is that they are components of cell membranes.
Explanation:
Lipids are biomolecules formed by the binding of fatty acids, important for structure, compound synthesis and energy reserve.
In living beings, one of the most important functions of lipids is to be the main component of cell membranes.
Specifically, phospholipids associate to form a double layer, called lipid bilayer, capable of acting as a semi-permeable membrane, due to its non-polar or hydrophobic character. In this way, membrane lipids fulfill a structural and protective function of the cell and its contents.
Regarding the other options:
Proteins are made up of amino acids, not lipids. Lipids are not constituents of the DNA structure.1.The structure most responsible for maintaining cell homeostasis is the
