Biology
1 answer:
nasty-shy [4]3 years ago
7 0

Answer:

A) polar

Explanation:

Polar molecules contains  partial positive and partial negative charge as in all polar molecules two atoms have unequal sharing electron. Due to unequal sharing of electrons, one atom that attracts valence electrons strongly gains positive charge and other gain negative charge.

For example water, water is a polar molecule having partial negative and partial positive charge because the oxygen atom in water attracts electrons more strongly than the hydrogen atoms.

Hence, the correct answer is "A) polar".

the first cells likely to encounter a pathogen, such as phagocytes, are professional antigen presenting cells (apcs). this means
Zepler [3.9K]

Professional antigen-presenting cells, such as phagocytes, are the first cells to encounter a pathogen (apcs). This means they have the ability to activate cells of the adaptive immune system.

<h3>What is meant by Pathogen?</h3>
  • A pathogen is an organism that infects its host with disease, and the severity of the disease symptoms is referred to as virulence.
  • Pathogens include viruses, bacteria, unicellular and multicellular eukaryotes, and a wide range of other organisms.
  • The bone marrow of an average healthy adult generates 100 billion new neutrophils per day. Because there are so many neutrophils in the body at any given time, they are often the first cells to reach the site of an infection.
  • Long thought to be a component of the innate immune system, complement has recently emerged as an important regulator of the adaptive immune response.

Therefore the correct option is D)  can activate cells of the adaptive immune system.

Explain why the ratio of motor neurons to muscle fibers is greater in muscles that control eye movement than in postural muscles
EleoNora [17]

Answer:

The muscles of the eye cover a greater number and in turn carry out greater fine motor skills.

Explanation:

Alpha motor neurons are neurons that invent the skeletal muscle, that is, striated, so that through the motor plate that is the unit that unites them, an action potential is transmitted that contracts the sarcomeros of the elastic fibers and the z lines. come closer, each eye movement is much more precise than the locomotion of the lower limb, which carries greater innervation in each muscle bundle due to the specificity of the movement, this is how more alpha motor neurons are required to mobilize the eye than a leg.
