How can a restive trait be expressed

Answer:

last one is the correct answer

Answer: When it comes to the connection between beetles and self-heating flowers, scientists have concluded that self-heating flowers have a competitive advantage over other types of flowers since they produce heat as a reward for pollinators.

The flowers' strategy has proven to be successful in attracting beetles, which are drawn to the heat and, as a result, pollinate the flower.

When it comes to flower competition, this provides self-heating flowers with a competitive edge over other non-self-heating flowers.

What are self-heating flowers, exactly?

These are flowers that can heat up to as much as 20 degrees Celsius above the ambient temperature as a result of the respiration of their flowers. When insects visit such plants, they get a warm and attractive welcome that invites them to stay longer.

This serves as a reward for the pollinators that come to the flowers in question as they are more likely to return to plants that provide rewards.

Epithelia are tissues that cover and line the surfaces of organs and other structures in the body made up of tightly packed cells that are held together by special junctions.

Polarity: Epithelial cells are polarized, meaning that they have different surfaces. The apical surface is the surface that faces the outside of the body or the lumen of an organ. The basal surface is the surface that faces the underlying tissue. The polarity of epithelial cells allows them to transport substances from one side of the cell to the other.

Attachment junctions: Epithelial cells are attached to each other by a variety of junctions, including tight junctions, adherens junctions, and desmosomes. These junctions help to hold the cells together and prevent them from separating.

Secretory cells: Many epithelial tissues contain secretory cells, which produce and release substances such as mucus, enzymes, and hormones. These substances help to protect the body, digest food, and regulate hormones.

Receptive cells: Some epithelial tissues contain receptive cells, which are able to detect changes in the environment. These cells can detect changes in temperature, pressure, and chemicals. They can also detect light and sound.

Joining small molecules (monomers) together to form longer chains (polymers) requires a process called a dehydration reaction.

The correct answer is option B.

When small molecules, or monomers, are joined together to form longer chains, or polymers, the process involved is called a dehydration reaction, also known as a condensation reaction or polymerization. In this process, a covalent bond is formed between two monomers, resulting in the release of a water molecule.

During a dehydration reaction, the hydroxyl (OH) group of one monomer combines with the hydrogen atom (H) of another monomer, forming a covalent bond. As a result, a water molecule is eliminated, hence the term "dehydration." The remaining components of the monomers join together to form a polymer chain.

This process is the reverse of hydrolysis, which involves breaking down polymers into monomers by the addition of water molecules. In a hydrolysis reaction, a water molecule is used to break the covalent bond between monomers, resulting in the separation of the polymer into its constituent monomers.

The dehydration reaction is essential for the synthesis of various biological macromolecules, such as proteins, nucleic acids, carbohydrates, and lipids. Through this process, monomers are linked together to form complex polymers with specific structures and functions.

It is important to note that while dehydration reactions are commonly associated with the formation of polymers, they can also occur in other contexts. For example, when two molecules react to form a larger molecule while eliminating a water molecule, it is still considered a dehydration reaction.

In conclusion, the process of joining small molecules (monomers) together to form longer chains (polymers) involves a dehydration reaction, which results in the release of a water molecule. This process is essential for the synthesis of various biological macromolecules and is the reverse of hydrolysis, which involves the breakdown of polymers into monomers through the addition of water.

Explanation:

But when it comes to the word atom, we have to go to ancient Greece of 400 B.C. And there was a brilliant philosopher named Democritus, and he proposed the Greek word atomos, which means uncuttable. And so as he explained, all matter was eventually reducible to discrete, small particles or atomos. Mendeleev realized that the physical and chemical properties of elements were related to their atomic mass in a 'periodic' way, and arranged them so that groups of elements with similar properties fell into vertical columns in his table. Electrons that have full outer shells have more in common with each other than those with partially full outer shells. The more full the outer shell is, the more stable the element.By having the periodic table laid out in the shape of a castle, scientists can easily observe each element and its properties. Heavier elements have more shells that can hold larger numbers of electrons. What really matters for each element's behaviour, however, is how many electrons it has in its outer shell. That number tends to fit nicely with the way the table is arranged, namely to place elements with similar properties in the same group.

Pedigrees show how a trait is inherited throughout several generations.

Explanation:

We can eliminate the second answer choice because pedigrees show a trait passed through multiple generations, not just a trait passed from parents to the first set of offspring: the purpose of a pedigree is to see the pattern of how the trait passes, so there needs to be more than a generation of just parents and the first set of offspring. The third statement can also be eliminated because the trait being tracked might not always be one that leads to sickness. This leaves the first statement, which is correct.

If a bacterium reverses the direction of rotation of its flagella, it will change the direction of its movement.


Flagella are whip-like structures that extend from the surface of bacteria and are responsible for their movement. When flagella rotate counterclockwise, they form a bundle that propels the bacterium forward. However, if the direction of rotation is reversed, the flagella become disorganized and the bacterium will change direction. This reversal of direction is caused by a switch in the rotation of the flagellar motor proteins, which control the movement of the flagella. The ability of bacteria to change their direction of movement is important for their survival, as it allows them to navigate towards or away from certain stimuli, such as nutrients or toxins.

a. A describes the effect of light intensity on photosynthesis.

Explanation:

In plants and other primary producers, photosynthesis is a biological mechanism that is vital to energy production. Energy-containing carbohydrates are derived from light, water and carbon dioxide in the form of glucose molecules.

The waste product oxygen is released as a result. Photosynthesis depends on many variables, including:

It is a rate-limited reaction. Since photons or particles of light provide the energy required for the reaction, high intensities of light increase the photosynthetic rate. From the graph shown, as the intensity increases steadily, so does the rate- but at too high of an intensity, it ceases to affect the rate of photosynthesis, which becomes constant or plateaus.

Beyond this point, either the supply of carbon dioxide or the temperature limits the reaction. For instance, at high intensities tissues may even be damaged by high temperatures or heat.
