Why have scientist devised a system of comparative weights for atoms rather than using actual weights
Answer:
Because of multiple reasons:
Explanation:
Atoms are way too small to weigh.They couldn't use weight, they would have to use mass.Some atoms are free-floating, because they are the air.If they even made a scale that measured each atom, it would also catch the air atoms as well, unless they had a vacuum chamber, but even then, no one can make a perfect vacuum, space is not even a perfect vacuum...Hope this helps.

During light detection in a photoreceptor, light directly causes what molecular change?.
During light detection, the light causes a retinal change from cis to trans conformation in regards to the opsin protein.
What is a photoreceptor?Photoreceptors are the name we use to refer to a specialized form of neuron cells. These cells are crucial in our ability to see, they allow vision. Their job is to receive and interpret light as information. They do this using a protein named opsin, as well as specific conformations of the retina, such as cis or trans, which change with the light.
Therefore, we can confirm that during light detection, the light causes a retinal change from cis to trans conformation in regards to the opsin protein.

Explain the structure and function of the eye as a sensory receptor including the role of;
A) The cornea and lens
B) The iris
C) Rod and cone cells in the retina
NOTE - the letters listed are NOT answers, they are separate points that need clarifying.
Answer:
A) The cornea is the transparent outer covering of the eye,The lens is a curved structure in the eye that that bends light and focuses it for the retina to help you see images clearly.The lens works together with the cornea to focus light correctly on the retina. When light hits the retina (a light-sensitive layer of tissue at the back of the eye), special cells called photoreceptors turn the light into electrical signals.
B)The iris is the part of the eye that makes up your eye color. A circular muscle with a hole in the middle.The iris controls the amount of light that enters the eye by opening and closing the pupil. The iris uses muscles to change the size of the pupil. These muscles can control the amount of light entering the eye by making the pupil larger or smaller.
C)Rod cells are highly sensitive to light and function in nightvision, whereas cone cells are capable of detecting a wide spectrum of light photons and are responsible for colour vision.

Why are the lysosomes useful during entrapment of particles?
Answer:
Lysosomes
Explanation:
Lysosomes are membrane-enclosed organelles that contain an array of enzymes capable of breaking down all types of biological polymers—proteins, nucleic acids, carbohydrates, and lipids. Lysosomes function as the digestive system of the cell, serving both to degrade material taken up from outside the cell and to digest obsolete components of the cell itself. In their simplest form, lysosomes are visualized as dense spherical vacuoles, but they can display considerable variation in size and shape as a result of differences in the materials that have been taken up for digestion. Lysosomes thus represent morphologically diverse organelles defined by the common function of degrading intracellular material.

If a deer eats grass, what percentage of energy will the deer acquire from the grass? 0. 1 percent 1 percent 10 percent 100 percent.
The deer eats grass, the percentage of energy will the deer acquire from the grass will be dependent on the food chain then the accurate solution is 10 percent.
In a food chain, the simplest 10 percent of the strength is transferred from one trophic stage to another. The grass is the manufacturer and the deer is the number one consumer, so, whilst the deer eats the grass, it acquires 10 percent of the entire strength of the grass. Rest strength is dissipated withinside the surroundings thru the metabolic tactics taking location withinside the grass.What is the position of deer in the food chain?The 2nd trophic stage includes organisms that consume the producers. These are known as number one purchasers or herbivores. Deer, turtles, and plenty of varieties of birds are herbivores. Secondary purchasers consume the herbivore.
Thus it is clear that 10 percent of energy will the deer acquire from the grass.

Why is carpolestes a prime candidate among plesiadapiforms to be a euprimate ancestor?.
Answer:
Why is Carpolestes a prime candidate among plesiadapiforms to be a Euprimate ancestor? It had an opposable thumb. It had a nail instead of a claw on its first foot digit.
It had an opposable thumb. Its first foot finger had a nail rather than a claw. Plesiadapiforms were previously thought to be extinct members of the order Primates.
What is the Plesiadapiforms?Carpholites has a two-chambered auditory bulla, like Tarsius, which distinguishes it from early EU primates and all other known Plesiadapiforms.Plesiadapiforms are primitive primates, which means they lacked some primate characteristics while exhibiting others. Plesiadapiforms means "nearly adapiform," and refers to Plesiadapiforms that resemble some adapiforms (or adapoids; later-appearing species).Plesiadapiforms were on a much lower evolutionary stage than modern primates, possibly comparable to living tree-shrews despite sharing some skeleton traits. Plesiadapiforms first appear in the fossil record between 65 and 55 million years ago, though many had become extinct by the Eocene. They were possibly the first mammals to have finger nails instead of claws.To learn more about Plesiadapiforms, refer to:

What do you mean by Epithelial tissues?The epithelial tissues may be defined as a kind of body tissue that constitutes the surface on all internal and external surfaces of your body, lines body cavities and hollow organs, and is the major tissue in glands.
Proximal convoluted tubules (PCT) are formed by the simple cuboidal tissues in a brush-like border of microvilli to enhance the area of absorption of water and nutrients.
