What is the role of cells in vision?Two types of specialized cells are found in the eye for vision. These are named as rods and cones. These cells are called as photoreceptors as they are sensitive to light and thus functions in response to light.
Rod cells function in response to dim light and thus are active during the night time whereas cone cells impart colour vision.
These photoreceptor cells detect the light and convert them into electrical signals. Such electric signals travel to the brain from the retina through optic nerve. Brain thus helps in the perception of objects.
Defects in the rod cells leads to night blindness. It is also due to the deficiency for vitamin A which is pre-requisite for the activation of rod cells. Colour blindness (inability to distinguish between primary colours) can result if the cone cells are damaged.
Thus, photoreceptors cells are important in vision and image formation.

How does natural selection enable species to changes their body shape, appearance, and/or size over time? *
A) Individuals that are better adapted to their environment survive and reproduce.
B) Overproduction provides food for stronger members of the species.
C) Environmental changes kill weaker members of the species.
Answer:
A
Selective pressures( Predators, less food etc. ) will cause the less fit variation of a species to decrease in population, causing them not to be able to reproduce. The more fit variation would be able to reproduce more so that over time, the individuals in the species will have the features of the more fit variation.

Explanation:
The statement that correctly describes a feature of the rock cycle is: Rocks change from one type to another. In the rock cycle, rocks can be transformed through different processes. The correct option is B.
What is the rock cycle?The rock cycle is a process by which rocks are transformed from one type to another through a series of physical, chemical, and biological processes. The rock cycle involves the transformation of igneous, sedimentary, and metamorphic rocks, and these three types of rocks are related to one another.
The process of the rock cycle is continuous and does not follow a specific order as rocks can change from one type to another in any direction. The rock cycle is essential to the formation and recycling of rocks on Earth.
Therefore, the correct option is B.

Starting from glucose and utp and atp, how many high-energy bonds are broken/consumed directly to add that glucose to a glycogen molecule?
Answer: 2
Explanation:
A total of 2 high-energy bonds are broken/consumed directly to add that glucose to a glycogen molecule that is ATP.
What is Glucose activation?Glucose-1-phosphate reacts with the excessive strength nucleotide uridine triphosphate (UTP) to present uridine diphosphate glucose (UDPG) and pyrophosphate (PPi).
During glycolysis, glucose in the end breaks down into pyruvate and energy; a complete of two ATP is derived withinside the process. (Glucose + 2NAD+ + 2ADP + 2Pi --> 2 Pyruvate + 2NADH + 2H+ + 2ATP + 2H2O). The hydroxyl organizations permit for phosphorylation. The unique shape of glucose utilized in glycolysis is glucose 6-phosphate.To learn more about the glycogen refer link :

What are the 3 types of neurons?
Tq! :)
Answer:
sensory, motor, and interneurons.
Explanation:
For neurons in the brain, at least, this isn't an easy question to answer. For the spinal cord though, we can say that there are three types of neuronssensory, motor, and interneurons.
Answer:
Afferent "Sensory" Neuron
Interneuron "Associative Neuron"
Efferent "Motor" Neuron
Explanation:
The Afferent Neuron or Sensory Neuron receives information from the sensory receptors and carries the impulse from the sense receptors to the central nervous system. In this example the touch receptors in the skin are relaying information through the Afferent "Sensory" Neuron from the environment to the spinal cord.
The Interneuron or the Associative neuron is the transfer station or the decision making neuron. In the case of the reflex arc the Interneuron would make a decision to respond or not respond based upon the intensity of the stimulus.
The Efferent Neuron of Motor Neuron would then return the impulse back to the muscle or gland that would need to respond.

organisms that have average traits
organisms that have extreme traits
organisms that have the greatest number of offspring
organisms that are the largest and strongest
Answer:
Organisms that have extreme traits.
Explanation:
Disruptive selection is a specific type of natural selection that describes changes in population genetics. In disruptive selection, both extreme values for a trait are favored over intermediate values. As a result, the population is divided into two distinct groups and the variance of the trait increases.
Answer:
B. organisms that have extreme traits
