a. All of the zoo cheetahs come from just a few common ancestors.
b. The number of individual cheetahs currently in Zoos must be very low.
c. The variety of trats found in wild cheetahs is very narrow, possibly due to only a few of the animals surviving some event or series of events in thepast.
d. Even aner several generations, the baby cheetahs produced at your zoo wil show very ame geneto variaton.

Answer:

A

Explanation:

I'm quite sure its a, might be wrong.

Because there is just a little amount of space on the rock, the number of barnacles there is unaffected. So, the correct option is A.

Because they are an arthropod species and members of the subclass Cirripedia mostly in Crustacea subphylum, barnacles are linked to crabs and lobsters. Often found in erosive environments, shallow and tidal seas are where barnacles prefer to live.

Cirri, or feather-like appendages, are used by barnacles to feed. The cirri scan the water for microscopic organisms as they quickly extend and retract through the aperture at the top of the barnacle. If they detect a potential threat, they swiftly retreat into their protective shells.

Few barnacle species are parasitic, and the majority of barnacle species are not harmful to other creatures. They protect the animal they feed on by filtering feeding food particles from the water.

Therefore, the correct option is A.

Answer:

No

Explanation:

No, plants do not take in air with their roots. Roots are designed to absorb water and minerals from the soil. In order to get the air and carbon dioxide they need for photosynthesis, plants have specialized structures called stomata in their leaves and stems that allow air to enter and exit. These stomata regulate the movement of gases into and out of the plant, so the plant can take in the carbon dioxide it needs and release the oxygen it produces.

Diabetes can be properly designed by using the letter symbol for the gene concerned as a lowercase letter (d) because it is a recessive trait.

A recessive trait is any phenotypic feature that is expressed when two recessive alleles are found in an individual and show complete dominance by means of dominant alleles that masks recessive expression.

For example, if a normal female and a normal male in the population have a child who is diabetic, then the probability that their next child will be 25% (parents are heterozygous for the trait).

One function of the structure labeled Y is to pump blood into the heart.

The correct option is B.

Structure Y refers to the pericardial cavity which surrounds the heart in snails.

The pericardial cavity plays an important role in the circulation of hemolymph, the snail's equivalent of blood. It functions as a chamber that receives and stores oxygenated hemolymph from the gills and pumps it into the heart, which then distributes it throughout the rest of the body.

Therefore, option "pump blood into the heart" is the correct function of structure Y. Option "digest prey" is not related to the structure Y in snails, and option "remove carbon dioxide from blood" and "capture prey" are not relevant to the circulatory system of snails.

In the genetic cross between two F1 hybrid pea plants for spherical seeds, the F2 generation is expected to yield 75% spherical seeded plants and 25% wrinkled seeded plants.

This is because the F1 generation is heterozygous for the spherical seed trait (Ss), and when crossed, the offspring have a 1:2:1 genotypic ratio of SS:Ss:ss. The SS and Ss genotypes both result in spherical seeds, while the ss genotype results in wrinkled seeds.

Therefore, 3 out of 4 possible genotypes in the F2 generation will produce spherical seeds, resulting in a 75% chance of spherical seeded plants.

The structural difference between a compound eye and a human eye is significant, as they have evolved to serve different purposes and have different ways of perceiving the environment.

Many insects and some crabs have compound eyes, which are made up of numerous small optical components called ommatidia. There are individual nerve impulses, photoreceptor cells, and lenses in each ommatidium. Because each ommatidium in compound eyes contributes a tiny portion of the overall picture, the outcome is a mosaic-like image formation. This makes it possible to see a large area and recognize movement.

The cornea, pupil, lens, retina, and optic nerve are all interconnected components of the human eye, which is a complicated optical system. The retina, which has specialized photoreceptor cells called rods and cones that transform light into electrical impulses, is illuminated by the lens and eye working in tandem.  These signals are then transmitted to the brain via the optic nerve, where they are interpreted as visual information.

Fig. 5.1 shows a graph of tidal volume (the amount of air inhaled and exhaled during normal breathing) and breathing rate (the number of breaths per minute) for a soccer player before and during a match.

Before the match, the pattern of breathing is relatively stable, with a consistent tidal volume and breathing rate. This indicates that the player is in a state of rest and is not expending a lot of energy.

During the match, the pattern of breathing changes significantly. The breathing rate increases and becomes more erratic, indicating that the player is working harder and expending more energy. The tidal volume also increases, indicating that the player is taking in more air to meet the demands of increased physical activity.

Overall, the difference in the pattern of breathing before and during the match shows how the body responds to physical exertion and the increased demand for oxygen to support muscle activity. As the body works harder, breathing rate and tidal volume increase to meet the increased demand for oxygen and to remove carbon dioxide from the body.

Pumping CO2 gas into a greenhouse system is significant for several reasons. Greenhouse gases like CO2 are essential for plants to carry out photosynthesis, which is the process by which they convert sunlight into food. By adding CO2 to a greenhouse, it can help to increase plant growth and yield.

Here are some reasons why pumping CO2 into a greenhouse system is important:

Increased photosynthesis: Photosynthesis is a chemical process in which plants use sunlight to convert carbon dioxide and water into glucose, a form of sugar that is used as food. The addition of CO2 to the greenhouse system can help to increase photosynthesis, which means that plants will produce more food. This can result in faster growth, bigger plants, and higher yields.

Improved plant health: CO2 is essential for plant growth and can help to improve the overall health of the plants. By adding CO2 to the greenhouse system, it can help to create an environment that is more conducive to plant growth. This can lead to healthier plants that are less susceptible to disease and pests.

Improved crop yields: One of the most significant benefits of pumping CO2 into a greenhouse system is that it can increase crop yields. By increasing the amount of CO2 in the air, plants are able to produce more food, which can result in bigger, healthier plants with larger yields. This can be particularly beneficial for commercial growers who rely on high yields to generate income.

In summary, pumping CO2 gas into a greenhouse system is an effective way to improve plant growth and yield. By increasing the amount of CO2 in the air, plants are able to carry out photosynthesis more efficiently, which can lead to healthier plants and higher crop yields.

When the carbohydrate cellobiose is digested into two glucose monosaccharide sugars (by cellulase in certain fungal species), the resulting glucose monomers are properly defined as the products

The correct answer is option E.

When the carbohydrate cellobiose is digested into two glucose monosaccharide sugars by cellulase in certain fungal species, the resulting glucose monomers are properly defined as the products.

In a chemical reaction, reactants are the starting materials or substances that undergo a change, while products are the resulting substances formed after the reaction. In this case, cellobiose is the substrate, which is the molecule that undergoes the enzymatic reaction. Cellulase is the enzyme responsible for catalyzing the digestion of cellobiose into glucose monomers.

The enzyme cellulase acts as a catalyst in the reaction, facilitating the breakdown of cellobiose into glucose. Catalysts are substances that increase the rate of a chemical reaction without being consumed or permanently changed themselves. However, in the context of the given question, the glucose monomers produced are the final result or product of the enzymatic digestion process.

Science is probably the most pressing factor in the destruction of the Earth. As science gets more and more advanced, the materials that we consume will get larger and larger too. Science and research have progressed greatly through the ages. Take naval warfare as an example. A Spanish galleon from the mid-1600s was 1500 feet long and made of wood coming from almost 2000 trees and taking two years which was determined as one of the strongest forces on the sea. The US today progresses with the Zumwalt, a ship that costs 4.4 billion dollars to produce. A massive change in materials and price. Additionally, the need for resources such as crude oil and coal limits the amount that the Earth can replenish. Science is used to solve our problems. However, each new invention in science causes more problems. The invention of the car in 1886 was extraordinary, changing the face of travel forever. This also would cause a large amount of global warming, which we are dealing with now. Take computers.

The cell membrane's inside is hydrophobic, meaning that water won't cling to it. In order to effectively separate fluid inside the cell from fluid outside the cell, phospholipids form a two-layer cell membrane.

Large hydrophilic polar or ionic molecules find it difficult to pass through the phospholipid bilayer. The cell membrane prevents the passage of any size charged atoms or molecules.

While the tails (the lipid component) are non-polar, the heads (the phospho part) are polar. The tails, which face the inside of the cell membrane, are "hydrophobic" (fearful of water), whereas the heads, which make up the exterior and inner linings, are "hydrophilic" (lovers of water).
