Answer:
preexisting cells :)
Explanation:
Answer:
Cell theory is the historic scientific theory, now universally accepted, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells. Cells are the basic unit of structure in all organisms and also the basic unit of reproduction.

A plant's life cycle has two main parts, so it is called the _____.
A.alternation of generations
B.meiosis
C.pollination
D.fertilization
Answer:
A. alternation of generations
Explanation:
Basically, a plant's life cycle has two main parts, namely a diploid and a haploid phase. Since the plant alternates between these two phases in its life cycle, the alternation is typically called the alternation of generations.
Hope this helped!
A. alternation of generations
Alternation of generations (also known as metagenesis) is the type of life cycle that occurs in those plants and algae in the Archaeplastida and the Heterokontophyta that have distinct haploid sexual and diploid asexual stages.
How is proper science validated?
Answer:
by experimental repeatability, which enables to demonstrate the accuracy and reliability of the scientific study.
Explanation:
Scientific ideas and theories are used to explain observations and phenomena from the real world. Scientific validation comes by acceptance of the scientific community, which is generally achieved by scientific publications in well-reputed peer-reviewed journals. In order to be validated, these explanations must be repeatedly tested by using the scientific method, thereby proving the effectiveness of the proposed research method used to obtain information.
Most organisms with chloroplasts belong to what Kingdom?
Answer:
Mostly the plant kingdom.
Explanation:
Plants are most commonly found with chloroplasts, which give them their green appearance.
What is one job proteins do NOT have in the body
1.serve as a layer of insulation
2.support the immune system
3.structure for tissues and organs
4.serve as enzymes
Answer:
1. serve as a layer of insulation
is not a job of proteins
Proteins do not serve as a layer of insulation in the body.
WHAT ARE PROTEINS:
Proteins are one of the four biomolecules in living organisms. Proteins are made up of long chains of amino acids linked together by peptide bonds.
FUNCTIONS OF PROTEINS:
Proteins in the body are synthesized to perform varying functions. These functions include:
Enzymes: Proteins are the major components of enzymes responsible for regulating series of biochemical reactions in the body. Structure for tissues and organs: Proteins make up the structural components of many tissues and organs in the body. For example, keratin is a protein found on the skin. Support the immune system: Proteins provide support for the defense system of the body.Therefore, among the many roles that protein play in the body, serving as a layer of insulation is not one of them. It is rather the function of LIPIDS.

Air masses always move in which direction?
Answer:
They move with the global pattern of winds.
Explanation:
Answer:
They move with the global pattern of winds. In most of the United States, air masses generally move from west to east. They may move along with the jet stream in more complex and changing patterns. When an air mass moves to a new region, it carries along its characteristic moisture and temperature.

Which of the following can be harvested into a fuel?
water
wind
coal
gas
Answer:
gas can be used for fuel
Explanation:
Your lab group is experimenting with the diffusion of molecules across a membrane. Dialysis tubing is used as a model cell
membrane, because is it semi-permeable, allowing small molecules to cross the membrane, but NOT larger molecules, like starch
A starch solution is placed in the dialysis tubing and then the dialysis tubing is placed in an iodine and water solution. lodine is
used as an indicator for the presence of starch. Normally, iodine is a yellow-brown color, but in the presence of starch, it turns a
deep purple. After observing the experimental setup for 20 minutes, the iodine solution remains brown, but the starch solution
inside the dialysis tubing is purple and swollen. Based on what you learned from the lab, starch is MOST likely to cross the cell
membrane at which of the points indicated on the diagram?
ah
ing
Starch requires ATP energy for transport and therefore cannot cross the dialysis tubing into the iodine solution.
In chemiosmosis in mitochondria, protons flow from the intermembrane space into the matrix. In what direction do protons flow during chemiosmosis in chloroplasts
Answer:
Protons flow from the thylakoid space into the stroma of the chloroplast
Explanation:
Chemiosmosis is one of the two events that occur in oxidative phosphorylation (the other being electron transport chain). Chemiosmosis, which occurs to synthesize ATP in both cellular respiration and photosynthesis, is the process whereby protons (H+) move across a membrane via osmosis. In other words, chemiosmosis builds the proton gradient required to power ATP synthesis via the aid of an enzyme called ATP synthase.
In cellular respiration, chemiosmosis occurs when protons flow from the intermembrane space into the matrix while in PHOTOSYNTHESIS, cheniosmosis occurs when protons flow from the thylakoid space into the stroma of the chloroplast.
The flow of protons takes place from the thylakoid space into the stroma of the chloroplast during the chemiosmosis in chloroplasts.
What is chemiosmosis?It is one of the events, which takes place during oxidative phosphorylation. It generally takes place to produce ATP in both the process of photosynthesis and cellular respiration. In the process, the protons move across a membrane through osmosis.
It can also be stated that building of the proton gradient for the synthesis of ATP takes place by chemiosmosis with the help of an enzyme known as ATP synthase.
Chemiosmosis takes place when flow of protons takes place from the intermembrane space into the matrix during cellular respiration. While in photosynthesis, chemiosmosis takes place when flow of protons takes place to the stroma of the chloroplast from the thylakoid space.
Thus, in chloroplasts, chemiosmosis takes place when flow of protons takes place from the thylakoid space into the stroma.

Describe how facilitated diffusion helps large molecules cross cell membranes. What kinds of proteins are involved?
Yeah yeah so :D,
Large polar molecules can only cross the membrane with the help of protein named channel protein and carrier protein.
So, this both proteins act like a gate, the large molecules enter the protein and the protein let the large molecules in to the membrane. (see the picture so that you can understand more, its carrier protein)
the only difference between channel protein and carrier protein is, channel proteins has fixed shape while carrier protein can flip.
Large or polar molecules like glucose can't pass through the phospholipid bilayer. Smaller molecules usually diffuse freely for example water and CO2.
Large molecules like glucose diffuse through channels. This is a form of passive transport. Carrier proteins are involved.
