Explanation:

At lower magnification, the structure of plant cell is not clear by stella but with the increase of magnification, the cell structure becomes enlarge and clearly seen different structures of plant cell by the individual. The boundary of plant cell is known as epidermis. The upper boundary of plant cell is upper epidermis and the lower boundary of plant cell is lower epidermis.

Answer:

This type of natural selection occurs when there are selective pressures working against two extremes of a trait and therefore the intermediate or “middle” trait is selected for. If we look at a distribution of traits in the population, it is noticeable that a standard distribution is followed: Example:  For a plant, the plants that are very tall are exposed to more wind and are at risk of being blown over. The plants that are very short fail to get enough sunlight to prosper. Therefore, the plants that are a middle height between the two get both enough sunlight and protection from the wind.

This type of natural selection occurs when selective pressures are working in favour of one extreme of a trait. Therefore when looking at a distribution of traits in a population, a graph tends to lean more to one side: Example: Giraffes with the longest necks are able to reach more leaves to each. Selective pressures will work in the advantage of the longer neck giraffes and therefore the distribution of the trait within the population will shift towards the longer neck trait.

This type of natural selection occurs when selective pressures are working in favour of the two extremes and against the intermediate trait. This type of selection is not as common. When looking at a trait distribution, there are two higher peaks on both ends with a minimum in the middle as such: Example: An area that has black, white and grey bunnies contains both black and white rocks. Both the traits for white and black will be favored by natural selection since they both prove useful for camouflage. The intermediate trait of grey does not prove as useful and therefore selective pressures act against the trait.

A strong acid is an acid that dissociates completely into its constituent ions in an aqueous solution, therefore, the conjugate base of a strong acid is weak. A conjugate base is the species formed after an acid loses a proton.

Acids and bases, in essence, are opposites. Acids donate protons, while bases accept them. When acids donate protons to water, they produce hydronium ions, while when bases donate hydroxide ions, they react with water to create hydroxide ions.

The stronger the acid, the weaker its conjugate base. Because strong acids donate their protons effectively, their conjugate bases are unable to accept them as efficiently as weaker acids. The stronger the base, the weaker its conjugate acid, which means that a strong base will have a weak conjugate acid. Acids and bases are two of the most essential chemical concepts because they play such a critical role in chemical reactions. Acids are molecular substances that donate protons, while bases are molecular substances that accept protons. Acids and bases can react with one another to create products that differ in their acidity.

Photosynthesis in chloroplasts involves major steps such as light absorption, electron transport, ATP synthesis, and carbon fixation. It begins with light-dependent reactions in photosystems I and II, followed by electron transport and ATP synthesis.

Step 1: Photosynthesis is a complex process that occurs in the chloroplasts of plants, involving several major steps such as light absorption, electron transport, ATP synthesis, and carbon fixation.

Step 2:Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose. It occurs in the chloroplasts, specifically in three main stages: light-dependent reactions, electron transport chain, and the Calvin cycle.

During the light-dependent reactions, light energy is absorbed by chlorophyll molecules in photosystem II (PSII) and photosystem I (PSI). In PSII, water molecules are split, releasing electrons, protons (H+ ions), and oxygen. The electrons move through an electron transport chain, creating a proton gradient across the thylakoid membrane. This gradient is essential for ATP synthesis by ATP synthase, using the energy from the electron flow.

In PSI, electrons are re-energized by absorbing more light energy and are ultimately used to produce NADPH, another energy carrier. The ATP and NADPH generated in the light-dependent reactions are then used in the Calvin cycle.

The Calvin cycle, also known as the light-independent reactions or carbon fixation, occurs in the stroma of the chloroplast. It uses ATP, NADPH, and carbon dioxide (CO2) to produce glucose (G3P), which serves as a building block for sugars and other organic compounds. The cycle regenerates the starting molecule, ribulose bisphosphate (RuBP), allowing the process to continue.

Explanation: there are a Varity of viruses that affect plant life such as the mosaic virus which causes discolored splotches on the plants leaves.

The loss of lichens and rise in the abundance of dark-colored moths during England's industrialization were both caused by industrial melanism.

As a result of industrial pollution, the tree trunks darkened and developed soot and smoke deposits that made it impossible for lichens to grow on the tree bark. The white-winged moths were unable to bury themselves among the lichens as a result. As a result, there were more black moths because their predators had a harder time seeing them while doing so with the white-winged moths (due to a reduction in lichens). Natural selection led to the selection of dark species, whereas light ones perished.

Austin and Marissa should observe the number of open stomata on one leaf, mist the leaf with water, wait one hour, and count the number of open stomata again.

In the epidermis of tree leaves and needles, there are cell structures called stomata that play a role in the exchange of water and carbon dioxide between plants and the atmosphere.

Stomata, the tiny pores on the outside of leaves and stalks, control how gases enter and exit leaves and therefore, how plants as a whole function. On all periods, ranging from minutes to millennia, they adjust to regional and global changes.

Guard cells are a pair of specialized epidermal cells that make up stomata. By adjusting the size of the stomatal pore, stomata govern water loss and the exchange of gases between the plant and its surroundings.

The element of fibrous joints that gives the joint its ability to resist stretching and control the amount of movement at the joint is collagen fibers. Collagen is a tough, fibrous protein that is the main component of connective tissues such as tendons, ligaments, Correct answer is option A

Collagen fibers are arranged in bundles and aligned in the direction of the stress applied to the joint. This allows the joint to resist tensile forces and maintain its shape and stability. Collagen fibers are also responsible for the toughness and durability of fibrous joints, making them ideal for joints that need to withstand a lot of stress and movement, such as those in the spine and pelvis.

In summary, collagen fibers are the essential element of fibrous joints that give them the ability to resist stretching and control the amount of movement at the joint. These fibers provide strength and stability, limiting the joint's range of motion and preventing dislocation. Without collagen fibers, fibrous joints would be weak, unstable, and prone to injury.

Answer:

I'm pretty sure it's a comet!

Explanation:

A comet's nucleus is like a snowball made of ice. As the comet nears the Sun, the ice starts to melt off, along with particles of dust. These particles and gases make a cloud around the nucleus, called a coma. A comet's nucleus, or heart, is the solid chunk of something in the center of its fuzzy coma.

Most comets have two tails. ... Because the comet dust particles are so small, they are pushed away from the Sun into a long tail. Another tail is made of electrically charged molecules of gas (called ions). Very rarely a comet will have a third tail made of sodium, which we usually don't see with our unaided eyes.

We can deduce from the list of chromosomes and the aforementioned question that we should expect 15% recombination between the W and G genes since the map distance between them is equivalent to 15 centimorgans. It's a choice (B).

The unit for describing a 1% recombination frequency used to measure map distance is the centimorgan (cM). The lowest frequency of recombination, or 3%, is predicted to occur between W and E based on this criterion, we can deduce. Assume P is the epistatic gene in charge of regulating the development of the tail.

The male lacks a tail and is recessive homozygous for the tail length gene, so the genotype of the male is PPtt, in accordance with the question, and the genotype of the female is ppTT. The dominant epistatic allele P specifies that there is no tail formation in the female, who has a long tail. The genotype PpTt and phenotype "no tails" are present in the offspring that is born following mating. Two springs with the same PpTt genotype are being crossed right now.

The apple reflects red light and absorbs all other visible wavelengths

Explanation:

The apple is only reflecting the color red and is absorbing the other colors of light (wavelengths)

The correct explanation why an apple looks red is that the apple reflects red light and absorbs all the other visible wavelengths. Thus, the correct option is A.

Light absorption is the process in which the light ray is absorbed by the matter and converted into a form of energy. In an atom, the electrons vibrate at a specific frequency, then this is called as the natural frequency.

Reflection is a phenomenon of light. When a ray of light approaches a smooth polished surface such as metal and the light ray bounces back, it is called the reflection of light. The incident light ray which land on the surface is reflected off from the surface. The light ray that bounces back is called the reflected ray.
