What happens to the light when you look at a green object?
When you look at a green object, the object reflects green light and absorbs other colors of the visible spectrum. The green light is then transmitted to your eye, where it is focused by the lens onto the retina.
The retina contains specialized cells called rods and cones that are sensitive to different wavelengths of light. The cones in the retina are responsible for color vision and are most sensitive to different colors in the visible spectrum, and when the green light reaches the cones, it triggers a neural signal that is sent to the brain, where it is interpreted as the color green. The absorbed light colors are not reflected and are green absorbed by the object, they are not transmitted to green the eye, so they are not perceived by the observer.

State a reason why the water lily lacks a waxy cuticle.
One reason why the water lily (Nymphaea spp.) lacks a waxy cuticle is because it is adapted to living in an aquatic environment. A waxy cuticle is a layer of cutin, a waterproof, protective coating found on the surface of plant leaves and stems. It helps to prevent water loss through evaporation and protect the plant from dehydration.
However, water lilies are adapted to living in an aquatic environment, where they are constantly surrounded by water. As a result, they do not need to worry about water loss through evaporation and do not have a waxy cuticle to prevent it. Instead, water lilies have evolved other mechanisms, such as thick, succulent leaves and stems, to help them absorb and store water.

The water lily lacks a waxy cuticle because it is generally present in the water, so it does not have the adaptation to save water, so it does not have the waxy cuticle, while these are the adaptations of the desert plants.
What is the significance of the water lily?The water lily is significant as it has an important role in aquatic ecosystems because it provides food for a wide variety of aquatic animals, such as insects and fish, while its roots can help stabilize shorelines, prevent erosion, and purify water by removing excess nutrients. Its seeds are of great interest to humans due to their high demands.

How does natural selection lead to increases and decreases of specific traits?
More individuals with beneficial mutations will survive than those without it, and it will lead to an increase in the expression of those certain traits throughout the population through increases and decreases of specific traits.
Any modification to a species' structure or behavior that makes it more suited to surviving and procreating in its environment is referred to as an adaptation. Random mutations can cause the expression of particular features to become more prominent. Natural selection will result in an increase in the expression of specific features throughout the population since more people with advantageous mutations will survive than those without them.
Physical characteristics of an organism, such as the bill on a bird or the fur on a bear, are examples of structural adaptations. Behavioral adjustments make up the rest. Organisms use behavioral adaptations to help them survive. Bird migration and calls are two examples of behavioral adaptations.

Why do men suffer from cardiovascular disease more than women?
Elevated low-density lipoprotein cholesterol is more likely to increase the risk of cardiovascular in men than in women
Men generally develop CVD at a younger age and have a higher risk of coronary heart disease (CHD) than women.
It appears that men's coping with stressful events may be less adaptive physiologically, behaviorally, and emotionally, contributing to their increased risk for CHD.
CVD is the leading cause of death worldwide, yet important differences exist between men and women

What happens to the molecules of a compound when it changes from a liquid to a solid?
When the compound changes from a liquid to a solid, the molecules lose their energy, they slow down and thus come together and closer.
Solid is one of the states of matter where the molecules or atoms of a compound stay close together in contact with each other and are not able to perform any movement. The kinetic energy of these molecules is very less and such compounds have a structural integrity.
Energy is defined as the capacity to do work or supply heat to any body. In any compound, the energy is stores in its chemical bonds. The transition of molecules from a less ordered state to a more ordered state results in the release of energy from the compound.

What are 3 differences between natural selection and selective breeding?
Environmental conditions, like as harsh habitats or competition for mates, that restrict survival and reproduction are what drive natural selection. The term "artificial selection" also applies to selective breeding.
Selective breeding is an artificial process where people step in and choose certain organisms to mate, whereas breeding is a natural process of mating between two species.
Three contrasts exist between selective breeding and natural selection:
Human involvement drives artificial selection. The selective pressure of the environment controls natural selection.Breeders are in charge of artificial selection. On Earth, biological diversity is greatly increased via natural selection.Contrarily, artificial selection makes it easier for the breeder to pass on desired traits.Learn more about breeding Visit: brainly.com/question/13614055

How is natural selection different from genetic engineering?
Genetic engineering uses a process of insertion of genetic material, which does not occur in nature, by a gene gun or other direct gene introduction methods, or by a specially built bacterial truck.
With the aid of sexual and asexual reproduction that occurs naturally, conventional breeding mostly relies on selection. In order to create the desired crops more quickly than through selective breeding, genetic engineering involves directly changing an organism's DNA.
Any form of selection that results from an organism's capacity for environmental adaptation is known as natural selection. Contrarily, artificial selection is selective breeding that is imposed by a third party, typically humans, in an effort to increase the frequency of desirable traits.

What phenomenon leads to calico pigmentation in female cats?
In cats, the genes for coat pigmentation are X-linked, resulting in an orange or black coat color depending on which copy of the X chromosome each cell has activated. X inactivation occurs only in cells with multiple X chromosomes. This characterize why almost all calico cats are female.
Known for their distinctive black, orange, and white coat patches, the calico cat is an example of a genetic process known as "lionization." Because calico cats have a genetic condition called spotting. Mottled animals have white skin or patches of white fur. This is controlled by genes that affect the ability of skin cells to produce the pigments responsible for color.
The X chromosome determines a cat's color, and female cats, like all female mammals, have two X chromosomes, but male mammals, including the common male cat, have an X chromosome and a Y chromosome.

Summarize the function of water during chemiosmosis
Chemiosmosis is the passage of ions down their electrochemical gradient over a structure bound to a semipermeable membrane.
Protons, also known as hydrogen ions, will diffuse from an area with a high proton concentration to a site with a low proton concentration. Using an electrochemical gradient of protons across a membrane, ATP can be produced.
The oxidation of water, which is "divided" into protons and oxygen by the oxygen-evolving complex, replaces the electrons lost from Photosystem II (OEC, also known as WOC, or the water-oxidizing complex). Ten photons must be absorbed by Photosystems I and II, four electrons must pass through the two photosystems, and two NADPH must be produced in order to create one molecule of diatomic oxygen (later used for carbon dioxide fixation in the Calvin Cycle).
