Monomers only In general, which type of molecules would be able to pass through a cell's membrane
The cell membrane is also called as the plasma membrane. It provides the protection for the cell and its cellular components from the external environment. It is basically selectively permeable and the regulates the movement of the molecules in and out of the cell. The cell membrane (plasma membrane) is a thin semi-permeable membrane that is surrounds the cytoplasm of the cell. Its function is to protect the integrity of the interior of the cell by allowing of the certain substances into the cell while keeping other substances out

(a) Pepsin is a protein-digesting enzyme found in the stomach. It
has an optimum pH of 2 and is fully denatured at pH 6. Sketch a
curve on the graph to show the effect of pH on the rate of
reaction of pepsin.
Please find attached a sketch of the rate of reaction enhanced by pepsin at various pH, which shows a peak in the reaction rate at a pH of 2, and a reduction to (almost) zero rate of reaction at a pH of 6.
How can the variation of the rate of reaction with pH be graphically presented?(a) The given parameters for the enzyme, pepsin are;
Type of enzyme = Protein–digesting enzymeLocation of enzyme = The stomachEnzyme optimum pH = 2pH at which the enzyme is denatured = 6Required;
A sketch of a curve that shows the effect of varying pH values on the reaction rate of pepsin.
Solution;
An enzyme is denatured when it is not able to function to affect the rate of a reaction due to the loss of its tertiary or three dimensional structure.
The rate of the reaction when pepsin is denatured at a pH of 6 can therefore be taken as zero.
The graph of the variation of the rate of reaction for pepsin with pH consists of a curve that has a peak reaction rate at a pH of 2, and slopes downwards towards a reaction rate of zero at a pH of 6.

Which would not be considered an organism
Mr. Shepherd has gone outside to shovel snow on a cold day. How does his body maintain a relatively constant body temperature? What is this process called?
The thermoregulatory center, which is primarily responsible for controlling body temperature, is situated in the preoptic area of the hypothalamus.
Homeostasis is the term used to describe the process of maintaining a constant internal environment within an organism.
Vasodilation and vasoconstriction, which result in an increase or reduction in blood flow to the skin, are the primary thermoregulatory mechanisms.
On the skin's surface (peripheral receptors), in the pre-optic region of the anterior hypothalamus (central receptors), and in other areas of the body exist thermal sensing cells or thermal sensors for heat and cold.Blood flow to the skin increases in hot weather (making it red), while it reduces in cold weather (the skin becomes paler).The body employs perspiration in addition to blood flow to control body temperature because sweating causes water on the skin's surface to evaporate and heat to escape, which lowers body temperature.We can therefore draw the conclusion that the internal environment, a significant indicator, and the maintenance of body temperature are strongly associated (homeostasis).

Question 1 Humans and African Apes share many characteristics yet each is a distinct species. 1.1 Name FIVE characteristics that humans share with African Apes. 1.2 Name TWO characteristics that differentiate humans from African Apes. (5) (2) 1.3 Describe how each of the following structures is different between humans and Apes: (a) Spine (b) Pelvic girdle (2) (2) 1.4 Explain the significance of the changes to the teeth of humans that show progression in evolution. (4) (15)
Since we are mammals, primates, and hominoids, we have a lot in common with all of these other animal species, especially with our closest relatives, the apes. Our species, Homo sapiens, belongs to the genus Homo, but we are also hominins. Knowing our evolutionary history means knowing what we share with other primates as well as what has transpired in the 7–10 million years since we split from other African ape lineages. or more precisely, what transpired during the two million years of our own genus' existence. There is strong evidence that over the Pleistocene, our lineage endured substantial modifications to their bodies, behaviors, and ecologies, which led to the emergence of a human niche. This essay provides an overview of the significant parallels and distinctions between apes and humans.

Explain how injury can cause disease in pets.
Injuries can cause disease in pets because when the pets get hurt, some body parts are showing up which allows germs to enter the body. As a result, the pet gets sick.
Glad to help. :)
Answer:
Let's say a dog is in a race. This dog falls and gets scraped. If the injury consists of an open wound, that would leave a big opening for diseases to get in. Diseases can be harmful to the way pets function, just like us humans. If your pet is injured, do anything you can to treat it.

What are chemoautotrophs?The term chemoautotrophs refers to those organisms that use the energy from the sun to convert inorganic elements into compounds that are useful in the soil. There are several kinds of chemoautotrophs such as nitrosomonas and nitrobacter.
When we talk about multicellular organisms we are talking about the organisms that have more than one cell. The unicellular organisms are the organisms that have only one cell and we know that bacteria and certain kinds of fungi possesses only one cell.
Since we know that the chemoautotrophs are bacteria and bacteria are singe celled organisms, it is not possible to have a multicellular chemoautotrophs.

The equilibrium price according to the graph is $3.00. Option C.
What is an equilibrium price?An equilibrium price of a product is the price that equates the demand for the product with its supply.
In other words, the equilibrium price is the price at which demand equals supply.
On a graph of price against quantity, the demand curve slopes downward from left to right. On the other hand, the supply curve slopes upward from left to right on the same graph.
The price at which the demand curve intersects the supply curve on the graph is known as the equilibrium price.
From the graph, the approximate value of the equilibrium price is $3.00.

Energy and energy transition are depicted graphically and mathematically using energy flow diagrams, also known as energy flow charts.
Energy production used as unprocessed fuels to feed a system, supply of energy, transformation or conversion, losses, and energy in use can all fall under energy flow. The autotrophs that absorb energy from the sun are an excellent example of how energy moves through an ecosystem. The autotrophs are then consumed by herbivores, who convert the plant's energy into energy flow they can use. After that, carnivores eat the herbivores, and then other carnivores eat the carnivores is energy flow.

If you could genetically engineer any species of organism, what would it be? Would it be a unicorn? A dog-cat hybrid? Your own personal pet giant? Choose any species—real or not—that your imagination desires!
Write a paragraph describing your species, what it looks like, and where it lives. Think of any inherited traits the species has that might help it survive in its environment. Thinking of these traits now can help you come up with allele combinations in the next step. Now describe your species in the answer space.
If we can genetically engineer any species of organism, it would be a human-fish hybrid.
A human-fish hybrid would have lungs as well as gills to breathe so that life can be also possible under water.
It would be revolutionary because humans would not be just restricted to land but also be able to explore deep seas and oceans and found new types of minerals and other hidden treasures in the deep seas and oceans.
If somehow land became unfertile or flood hits, human will still be able to cope up with that and if by some reason the land collapses or air became all polluted, we can still live underwater and make a new civilization.
This hybrid will also provide us the power of echolocation because of the sonar detection feature in most fishes.
This hybrid would also be able to talk to other fishes if fishes can talk to each other, it will basically be like a living mermaid just not the fin.
