Biology
1 answer:
jolli1 [7]3 years ago

Answer:

Antibodies are produced by specialized white blood cells called B lymphocytes (or B cells). When an antigen binds to the B-cell surface, it stimulates the B cell to divide and mature into a group of identical cells called a clone.

A large asteroid impact occurs, kicking up dust that blocks the Sun and prevents plants from photosynthesizing. What would most
snow_lady [41]

Answer:

Many species would eventually die off because they lack a food source.

Explanation:

<u>Photosynthesis can be defined simply as the biological process of using light to synthesize food (in the form of glucose). It is a process that takes place in plants and involves the synthesis of sugar using inorganic products such as water and carbon dioxide.</u>

6CO_2 + 6H_20 + (energy) → C_6H_1_2O_6 + 6O_2

The process consists of two stages namely;

  • Light reaction
  • Light independent reaction.

The products from the light reaction are utilized in the light-independent reaction.

<em>Hence, without light energy, the process of photosynthesis cannot proceed and plants will not be able to manufacture foods. Without foods, many plant species would die off. </em>

Neurons in the ______ , control motor reflexes.
yan [13]

Neurons in the <u>spinal cord</u>, control motor reflexes, which allows rhythmic and automatic movements to be carried out.

The spinal cord represents the lowest level in the hierarchical system that regulates reflex motor activity, voluntary movements, and body posture.

Therefore, their neurons have been organized into circuits that participate in simple automatic gait movements and simple defensive movements (withdrawal of the muscle in the event of any aggression) through reflex responses.

The motor neurons of these circuits are located in the anterior horns where they are arranged forming the so-called "poles" of motor neurons, equivalent to true motor neuron nuclei.

  • Alpha motor neurons their axons are myelinated and they group together in the medulla and form columns that are known as motor nuclei.

  • Gamma (γ) motor neurons innervate muscle fibers of the muscle spindle.

  • Interneurons can be excitatory or inhibitory.

Therefore, we can conclude that neurons in the spinal cord, control motor reflexes, they present functional interactions between them and this allows rhythmic and automatic movements to be carried out with ease through reflex responses.
