where does reduction occur in an electrolytic cell
Answer: The Cathode
Explanation:
Reduction always occurs at the cathode, and oxidation always occurs at the anode. Since reduction is the addition of electrons, electrons must travel toward the site of reduction. In an electrolytic cell the negative charge is on the cathode, while the positive charge is on the anode.

How are thorns and spines related to drought resistance?
Answer:
To survive in drought conditions, plants need to decrease transpiration to limit their water loss. Some plants that live in dry conditions have evolved to have smaller leaves and therefore fewer stomata. Extreme examples are plants with leaves that resemble spiky thorns or spines.
(vii) All the activities of a cell is controlled by?
Answer:
nucleus
Explanation:
The nucleus controls all of the cell's activities, such as growth and metabolism, using the DNA's genetic information. Within the nucleus is a smaller structure called the nucleolus, which houses the RNA (ribonucleic acid).

Neural impulses are transmitted to bipolar cells when light energy enters the eye and triggers ________ in the rods and cones.
Neural impulses are transmitted to bipolar cells when light energy enters the eye and triggers CHEMICAL CHANGES in the rods and cones. This process is known as phototransduction.
Phototransduction refers to the process by which photoreceptors convert light into electrical signals.
Photoreceptors (i.e., rod and cone cells) are specialized cells in the retina of the eye which are capable of converting light into electrical signals and thus trigger different physiological processes.
Phototransduction is triggered by the activation of signaling proteins, that open or close ion membrane channels in photoreceptor cells.

objects are brought into focus on the retina by changes in the curvature and thickness of the
Objects are brought into focus on the retina by changes in the curvature and thickness of the lens.
What is eye lens?The lens basically directs light rays onto the retina. The lens is clear and replaceable if necessary. As we age, our lenses deteriorate, necessitating the use of reading glasses.
The lens is normally clear and is located behind the iris. The pupil directs light to the lens.
Small muscles attached to the lens can cause the lens to change shape, allowing the eyes to focus on objects that are close or far away.
Light bends (refracts) and focuses on the retina at the back of the eye as it passes through the lens.
The lens's thickness and curvature can be adjusted to focus on objects at various distances and ensure that the image is as clear as possible (this process is known as accommodation).
Thus, eye lens helps to focus the object.

Chlorophyll appears green because it…?
Answer:
Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green. Plants that use photosynthesis to make their own food are called autotrophs.
Answer:
A. absorbs green light
B. reflects green light
C. emits green light
ANSWER: B. reflects green light
Explanation:
our eyes can only see what objects reflect, so if it's appearing green then obviously it's reflecting the green light.

Rocks from the Ordovician Period contain evidence that plants began colonizing dry land at this time. Most experts agree that the ancestors of land plants first evolved in a marine environment, then moved into a freshwater environment and finally onto land.
Ordovician Period, in geologic time, the second period of the Paleozoic Era. It began 485.4 million years ago, following the Cambrian Period, and ended 443.8 million years ago, when the Silurian Period began. Ordovician rocks have the distinction of occurring at the highest elevation on Earth—the top of Mount Everest.

what factors determine if a species is fit to survive?
Answer: variation, reproduction, and heritability.
Explanation: Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population. Genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population.
All species must reproduce to survive. Organisms cannot live forever, so they must reproduce to allow their species to continue to live on. Reproduction is nature's way of allowing a species to survive.
Higher heritability means the trait evolves faster; fewer generations are required for the trait to increase to the same degree as a trait with lower heritability. For this reason, genetic correlation and heritability show how a trait might change from one generation to the next and into the future.
