Use the following terms to describe in detail how you visually perceive an object that you can see right now.

Answer: To see for example an apple first light that passes through the pupil is eventually reflected on the pupil, activating neurons in the retina. light waves that were reflected off the apple are changed into neural impulses (transduction) at the point of the retina, where neurons fire in response to light waves. Action potentials are released when neurons fire, sending an electrical charge through the neuron. Excitatory neurotransmitters are released when the action potential reaches the axon terminal, and that these neurotransmitters increase the chances that the next neuron will fire. Of course the neural message from the retina first passes through the thalamus, and then the thalamus routes the impulse elsewhere in the brain.

I hope it helps, Regards.

Do you think the challenge society faces with regard to feeding the world's growing population is an example of ecological carry
Minchanka [31]

Answer: Yes

Explanation:

Carrying capacity can be defined as the total number of members of the population of a species that an ecosystem can sustain in terms of providing resources in the form of food, shelter and others. When the resources are available in surplus then the population of a species increases exponentially but declines when resources become scarce. The human population is increasing tremendously all over the world this is supported by the resources like food, water, fossil fuels, air, minerals, and others. But some of these resources are decreasing due to overuse and may not be available in future to sustain the future generation.

If a dna analysis reveals that a cell has 60 ng of adenine and 20 ng of cytosine, how much thymine and guanine are in the cell?
Serggg [28]

Answer:

Thymine= 60 ng

Guanine= 20 ng

The complementary base pairing occurs between adenine and thymine and guanine and cytosine bases.

Explanation:

According to the Chargaff rule, a double-helical DNA molecule has an equal number or equal amount of adenine and thymine bases since adenine always pairs with thymine. Similarly, the amount of guanine base is equal to that of the cytosine base.

Chargaff rule is based on the complementary base pairing between purine and pyrimidine bases. According to the given information, the amount of adenine is 60 ng. Therefore, the cell would have 60 ng thymine. Similarly, the amount of the cytosine base in the cell is 20 ng which means that the cell would have 20 ng of guanine base.
