Answer:
A rise in temperature increases the kinetic energy and speed of particles; it does not weaken the forces between them. The particles in solids vibrate about fixed positions; even at very low temperatures. Individual particles in liquids and gases have no fixed positions and move chaotically.

White blood cells called B cells produce proteins that can be used for the treatment of certain illnesses. However, these B cells do not live for very long on their own. To keep the B cells growing for a long time in laboratories, scientists fuse the B cells with cancer cells (fused B-cancer cells) that do grow for a very long time. The particular cancer cells used for the fusion are treated with chemicals that make them unable to produce the nitrogenous bases adenine and guanine, but the B cells with which they are fused do produce these nitrogenous bases. The scientists grow the large fused B-cancer cells in a growth medium that contains necessary nutrients for the cells and includes a source of carbon.
(a) Describe the role of carbon in biological systems.
(b) The membranes of both B cells and the cancer cells are largely composed of phospholipids. Explain how, when the membranes are fused, the polar parts of the phospholipids from one cell will interact with the phospholipids from the other cell and how the nonpolar parts of the phospholipids from one cell will interact with the phospholipids from the other cell.
(c) Make a claim about the most immediate effect on the fused B-cancer cells if the fused cells are transferred to a growth medium that lacks a source of nitrogen.
(d) Provide reasoning with evidence based on the composition of biological macromolecules to support your claim.

Warm-Up Activity - Scenario: You are on a desert island. Alone. You must survive. The island has only one food source
that you've found: pineapples. It takes you 2 hours to harvest and cut up 1 pineapple (you have no knife!). You also want
to build your shelter. Each piece takes you 3 hours to build.
You have only 12 hours of sunlight and need to complete your tasks by sundown.
How will you spend your hours? Record your decision on your student notes.
Warm-Up-
1. Think back to the Warm Up activity. Why did you spend your hours the way you choose?
2. Whatlimits did you face? What tradeoffs did you make?
3. How does scarcity (limited resources) affect our economy and ability to produce?
Ce
Answer:
Explanation:
first day at the desert most of my hours will be spent making shelter for safety and then in the evening hunting is done for food.
Pineapple has an alternative way of opening without knife, which is to hit and roll on the ground severally exerting little force this allow the hard shell to be loosely packed and can be easily removed with hands from each box on the pineapple body.
The best way to maximize time is to do the most important and tedious work first.
Having limited tools to work with because it is a desert is a major challenge
Scarcity have put some industries on hold, many could not produce in large quantities because of Scarcity. The available resources is what is shared among many which makes its unavailable.
It affects the economy in terms of production and expected yield and return, it also affects people's standard of living.

How are humans affected by population growth of other organisms in anarea?
Answer:
yes
Explanation:
other organisms include things such as plants, insects and animals which can play a large role in the population. For example, if you have a sudden rise in the population of misquitoes that can be really bad since they can spread diseases to people when they are sucking blood. Antoher example is if there is a sudden growth of animals that eats a certain crop, then farmers will stuggle to maintain their crops and the list goes on. Hope this helps :)

Halfway through exponential phase, the temperature is lowered slightly below the
optimum. How will the growth curve change?
A. The cells will immediately enter death phase
B. The cells will enter lag phase
C.The slope of the exponential phase will become shallower
D. The slope of the exponential phase will become more steep
Which one is the best answer ? Choose only one answer
Answer:
B. The cells will enter lag phase
Explanation:
There are four identifiable phases of bacterial growth in a culture. These are: the lag phase, the exponential or log phase, the stationary phase, and the death or decline phase.
The lag phase occurs when there is need for the growing bacterial cells to adapt to new conditions. The adaptation period, i a time when the cells adjust themselves to the new conditions. The length of the lag phase varies considerably, depending on the initial and final conditions of the bacteria cells.
Hence, when the temperature is slightly lowered below the optimum halfway into the exponential phase, the cells will enter into lag phase

Which of the following statements is true about both fungi and protists
A) They can both photosynthesize
B) They reproduce by binary fission
C) Single-called organisms are found in both groups
D) Both groups are motile
The statement 'single-celled organisms are found in both groups' is TRUE (Option C).
Both protists and fungi are eukaryotic organisms, which means that their cells have the genetic material (DNA) compartmentalized in a cell nucleus and membrane-bound organelles.
Protists are single-celled microorganisms that belong to the Kingdom Protista. The protists represent a broad category of microorganisms that cannot be categorized as animals, plants, or fungi.
Moreover, fungi are organisms characterized by their cell walls, which contain chitin. These organisms are generally sessile like plants.
Fungi can be unicellular or multicellular. The unicellular fungi are known as yeasts (e.g., Saccharomyces cerevisiae).
In conclusion, the statement 'single-celled organisms are found in both groups' is TRUE (Option C).

Laboratory techniques for randomly linking together amino acids typically generate an insoluble polypeptide, yet a naturally occurring polypeptide of the same length is usually soluble. Explain.
Answer:
The answer has been explained below
Explanation:
The polypeptide has a natural selection due to an optimized sequence. It folds properly. At the outside it has hydrophobic residues. Inside it has polar residues. Now the random sequence of the synthetic peptide is going to be unable to give a good direction to a folding process. This will cause aggregation of hydrophobic side chains on various molecules. Bringing about the polypeptides precipitation from solution. Polypeptides that occur naturally have have the same length when they are in aqueous solution because of amino acid side chains that are present and are large with reactive functional groups.
