Warm-Up: What does it mean to be a prokaryotic cell? What
does it mean to be a Eukaryotic Cell? Which one came first?
(Think about the root words)
Answer:
eukrayotic cell l guess
Explanation:
A prokaryotic cell is a simple, single-celled (unicellular) organism that lacks a nucleus, or any other membrane-bound organelle. We will shortly come to see that this is significantly different in eukaryotes. Prokaryotic DNA is found in the central part of the cell: a darkened region called the nucleoid (Figure 1).
Unlike Archaea and eukaryotes, bacteria have a cell wall made of peptidoglycan, comprised of sugars and amino acids, and many have a polysaccharide capsule (Figure 1). The cell wall acts as an extra layer of protection, helps the cell maintain its shape, and prevents dehydration. The capsule enables the cell to attach to surfaces in its environment. Some prokaryotes have flagella, pili, or fimbriae. Flagella are used for locomotion, while most pili are used to exchange genetic material during a type of reproduction called conjugation.
Eukaryotic Cells
In nature, the relationship between form and function is apparent at all levels, including the level of the cell, and this will become clear as we explore eukaryotic cells. The principle “form follows function” is found in many contexts. It means that, in general, one can deduce the function of a structure by looking at its form, because the two are matched. For example, birds and fish have streamlined bodies that allow them to move quickly through the medium in which they live, be it air or water.
A eukaryotic cell is a cell that has a membrane-bound nucleus and other membrane-bound compartments or sacs, called organelles, which have specialized functions. The word eukaryotic means “true kernel” or “true nucleus,” alluding to the presence of the membrane-bound nucleus in these cells. The word “organelle” means “little organ,” and, as we learned earlier, organelles have specialized cellular functions, just as the organs of your body have specialized functions

Explanation:
What would happen to the concentrations of
Pyruvate, NADH and intermembrane H+ if the ETC
stopped working?
Answer:
Stay the Same, Increase, Decrease
Explanation:
Glycolysis produces pyruvate which is functioning normally if only the ETC (electron transport) stopped working because the ETC happens AFTER glycolysis, hence pyruvate is being produced and used at a normal rate (no change). NADH is produced in the cellular respiration stage PRIOR to the ETC so it is being created at a normal (or average) rate, however, it is not being used and split properly (meaning, not enough) in the ETC stage hence it's concentration increases. H+ decreases because it cannot be made if the prior step(s) were not complete.
What would happen to the concentrations of pyruvate, NADH and intermembrane H+ if the ETC stopped working are:
Pyruvate would stay the same and not be affected.that is it would remain the same.NADH would increaseH+ in the intermembrane would decrease.The concentration of the Pyruvate would not be affected If ETC stopped working and so this will make NADH would increase. Due to the fact that there is no electrons been transported down the chain, so therefore, no H+ would be moved and this in turn would make the concentration of H+ in the intermembrane space to reduce.Conclusively, we can therefore say that what would happen to the concentrations of pyruvate, NADH and intermembrane H+ if the ETC stopped working are:
Pyruvate would stay the same and not be affected.that is it would remain the same.NADH would increaseH+ in the intermembrane would decrease.Learn more from

which process produces large amounts of energy in a star by combining lighter elements into a heavier element
Answer:
Fusion
Explanation:
A star's energy comes from the combining of light elements into heavier elements in a process known as fusion, or "nuclear burning". It is generally believed that most of the elements in the universe heavier than helium are created, or synthesized, in stars when lighter nuclei fuse to make heavier nuclei.
Answer:
Nuclear fusion

which best describes a gene? 1. the short arm of a a chromosome 2. tightly coiled strands of DNA 3. the center of a chromosome 4. a segment of chromosomal DNA
Answer:
It's D. A segment of chromosomal DNA.
Explanation:
The functional and the physical element of genetics are called genes. They get inherited in the form of pairs from the parents of the offspring.
The genes are best described as:
Option 4. A segment of chromosomal DNA.
The statements can be explained as:
The short arm of the chromosomes is called a P-arm found on the chromosomes either the above or the below section of the centromere.Chromosomes are the tightly bonded thread-like configurations of DNA surrounding the histone protein.The centromere is in the middle of the chromosome that holds the two sister chromatids of the chromosomes.Genes are the element of the DNA that codes for proteins and determine the functions of the cells and attributes.Therefore, the correct option is D.
