Why are spines considered a physical characteristic adaptation in cactus?
A certain species has little genetic variation the rapid extinction of this species would most likely result from the effects of
Answer:
Environmental change
Explanation:
A species that has little genetic variation cannot evolve (change) in response to variable environmental conditions because genetic variation is the raw material on which natural selection operates to select individuals. Adaptation to changing environmental conditions only can occur when there is variation (either genetic or phenotypic variation). In consequence, a species with low genetic variation is at a high risk of extinction, especially in challenging environments.

5. The left ventricle is thicker than the right ventricle because it has to pump blood to a larger area of the body.
6. The difference between disinfectants and antiseptics is that:
Disinfectants kill microorganisms on surfaces, while antiseptics kill microorganisms on living tissue.
7. The life cycle of a tapeworm begins when an infected animal sheds tapeworm eggs in its feces. If a human ingests these eggs, they hatch in the small intestine and the larvae burrow through the intestinal wall and travel to the liver, lungs, or brain. In these organs, the larvae mature into adult tapeworms.
8. The main differences between cholera and typhoid are:
Cholera is caused by the bacterium Vibrio cholerae, while typhoid is caused by the bacterium Salmonella typhi. Cholera is spread through contaminated water, while typhoid is spread through contaminated food or water. Cholera symptoms typically develop within hours of infection, while typhoid symptoms typically develop within days of infection.9.

What tonicity term applies to the solution surrounding this cell?
Hypotonic. Since the black molecules can cross the cell membrane and water molecules are able to cross, the solution surrounding the cell has a lower solute concentration compared to the inside, causing water to move into the cell.
To determine the tonicity of the solution surrounding the cell in the given image, we need to consider the movement of water molecules across the cell membrane.
Based on the image, the black molecules can cross the cell membrane, while water molecules are also able to cross. Tonicity refers to the concentration of solutes outside the cell compared to inside the cell.
In this case, if the solution surrounding the cell has a lower concentration of solutes compared to the inside of the cell, water will move into the cell to equalize the concentrations. This would cause the cell to swell or potentially burst.
Therefore, the appropriate tonicity term for this situation is "Hypotonic." A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, resulting in water moving into the cell.
Hence, the correct answer is "Hypotonic."

Answer:
reactants = carbon dioxide & water
energy source = light
waste product = oxygen
primary energy = glucose
Explanation:
The energy source is light, reactants are carbon dioxide and water, the waste product is oxygen and primary energy is glucose.
What is photosynthesis?The sustainability of the significant number of life on Earth depends on photosynthesis. It is how almost all of the energy in the biosphere is made accessible to living beings.
All higher living forms on Earth consume photosynthetic organisms directly or indirectly since they are the primary producers that serve as the foundation of the planet's food webs.
Additionally, photosynthesis is responsible for producing virtually all of the oxygen in the atmosphere. The majority of creatures would vanish, there might soon be little food or other organic stuff on Earth, and the atmosphere would eventually be almost barren of gaseous oxygen if photosynthesis stopped.
Commonly used notation for photosynthesis is: 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂. This indicates that the reactants, six carbon dioxide molecules, and six water molecules, are transformed into a sugar molecule and six oxygen molecules, the products, by light energy being absorbed by chlorophyll (implied by the arrow).
The creature consumes the sugar, and as a byproduct, oxygen is produced.
Therefore, the energy source is light, reactants are carbon dioxide and water, the waste product is oxygen and the primary energy is glucose.

A hypotonic solution has a lower concentration of solutes than another solution. In biology, a solution outside of a cell is called hypotonic if it has a lower concentration of solutes relative to the cytosol. Due to osmotic pressure, water diffuses into the cell, and the cell often appears turgid, or bloated.

Search using the internet on how you can expand or enhance one's knowledge of animal/fish raising.
Answer:
Fish farming involves raising a variety of aquatic animals, such as fish, mollusks and shrimps in an enclosure such as a tank or pond. With the surge in demand for healthy animal protein the demand for fish and fish products is on the rise. Fish farms have the potential to produce fish for home consumption at about $0.90/lb which is a considerable saving when compared to supermarket prices of over $2.00/lb.
The first step for fish farming is to determine what you are going to do with your full-grown fish. You need to know the purpose, whether you are going to keep fish as a pet or for fish meat. This will decide a lot of things like the space requirements, equipment and capital requirements. If you intend to keep fish as a pet for showcase then a small tank or a backyard small fish farm is sufficient. If you intend to put a small fish farm with one or two ponds then also with a little business mindset you can market 1000 to 2000 lb of fish.
This will also require you to set up a business entity and have a business mindset.The costs associated with raising different types of fish varies because different fish need certain temperature water to live. The type of fish also decides the requirement of equipment and the feed cost. There are lots of laws about raising fish and animals, and even more, stringent laws related to raising animals that are going to be consumed as food.
Before starting fish farms or fish hatchery of any size or type it is advisable to check local laws and the need of permits to do so in your area.Normally you will get a license to operate your fish farm for a year which will be renewable. You need to submit the following documents to apply for the license:
Filled in application form
Sketch or aerial map of the facility layout, including dimensions
Copy of fish health certificate
Copy of stocking permit
Letter of a written permission from the landowner (in case if you are not the landowner)

Wave frequency is measured in units
called Hertz (Hz). One Hertz is defined as
one wave per second. Suppose a person
counted 10 waves passing by over a time
period of 1 second. What is the wave
frequency?
Answer:
it will be 10Hz ,because number of waves per second is 10 so we divide with 1second
The wave frequency of a wave which is passing by 10 waves over a time period of 1 second will be 10 Hertz (Hz).
What is Wave frequency?
Wave frequency can be defined as the number of waves which are passing through a fixed point in a given amount of time period. The SI unit for the wave frequency is the hertz (Hz), where 1 hertz is equal to 1 wave which is passing through a fixed point in the time period of 1 second. A higher-frequency wave has generally more energy than a lower-frequency wave with the same magnitude of amplitude.

Marianne is conducting an experiment on homeostasis in paramecium, which is a type of single-felled organism. Which of these observations provides the strongest evidence of a paramecium maintaining homeostasis
Hello. You did not present the answer options, which makes it difficult for you to receive a specific answer. However, I will try to help you in the best possible way.
One of the most common evidences that a paramecium is maintaining homeostasis is the pumping of water from the vacuoles present in its body.
The paramecium is a protozoan that lives in aquatic environments, mainly those composed of fresh water. The problem with this environment is that water is able to enter the paramecium organism in large quantities and this can promote the disruption of the organism through lysis of the cell. In this case, homeostasis must act quickly and pump water out of the body, through the cell vacuole.
Homeostasis is a regulatory system of the organism, which must promote the balance of the organism, whenever any external or internal factor tries to harm this balance.

In the citric acid cycle when an aldol addition occurs in a biological system, how do the amino acids contained in the Citrate Synthase enzyme help facilitate the reaction
Answer:
Citrate Synthase facilitates the formation of citrate by deprotonating Acetyl CoA and by protonating the carbonyl oxygen of oxaloacetate
Explanation:
Citrate synthase is a key enzyme in the citric acid cycle that functions to catalyze the formation of citrate from oxaloacetate and acetyl-CoA: acetyl-CoA + oxaloacetate + H2O >> citrate + CoA-SH (Coenzyme A ). This enzyme contains three amino acids at its active site that work together to catalyze the conversion of acetyl-CoA and oxaloacetate into citrate. This active site acts by abstracting (deprotonating) a proton from the alpha carbon of Acetyl CoA which serves as the nucleophile. Subsequently, the active site of the enzyme also protonates the carbonyl oxygen of oxaloacetate, which then suffers nucleophilic attack and thereby facilitating nucleophilic substitution reaction.
