Trace how the brain responds to stimuli through the nerves and neurons.​

Biology
1 answer:
user100 [1]3 years ago
4 0

Answer:

The correct answer is -The brain and the spinal cord respond and sends a signal down a motor neuron to a specific sensory stimulus.

Explanation:

Sensory receptors sense the changes that take place in the environment that is called stimuli by sensory neurons that transmit the signal from the sensory receptors to the brain.

The brain and the spinal cord make the central nervous system. This coordinates a response to a specific stimulus and sends a signal down a motor neuron and send a signal to the effector by motor neurons.

A Mother who is homozygous for Huntington's disease and a father who is homozygous normal want to have a baby. What genotypes an
natita [175]

Answer: The possible genotype for their child is Hh. All the children will be heterozygous for Huntington (Hh).

The possible phenotype for their child is Huntington disease.

Explanation: If H represents the trait for Huntington and h represents normal trait; and if Huntington trait (H) is dominant over normal trait (h), therefore the genotype of the mother who is homozygous for Huntington disease is HH and the genotype of the man who is homozygous normal is hh.

A cross between the man and woman will produce offsprings who are all heterozygous for Huntington disease Hh. Phenotypically, the offsprings will manifest as Huntington disease.

What produces all of the light in the universe?
storchak [24]

Answer:

<h2>Source of Light in Universe</h2>

<h3>Although the Sun doesn't light up the other stars, it does provide the daylight here on Earth; and the moon and planets we see are illuminated by that same sunlight. All stars produce light (and other kinds of energy) through nuclear reactions, using the energy stored in the tiny nucleus at the center of atoms.</h3>

Which of the following is true about photosynthesis?
il63 [147K]

Explanation:

Photosynthesis takes place within the chloroplasts.

Photosynthesizing cells in algae and plants have structures called chloroplasts. These contain chlorophyll, a specialized compound which facilitates the conversion of light energy to energy stored in carbohydrates in the process photosynthesis. Pigment molecules like chlorophyll in plants and other organisms reflect and absorb light at specific parts of light's electromagnetic spetrum.

Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released. This occurs in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent.

Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II. Additionally, in the light dependent reactions, within chloroplasts of plants, water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent; it reduces the molecule NADP to NADPH by providing H+ ions. NADP and NADPH are integral to the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules.
