A gymnosperm is classified as a:________
lyudmila [28]

Answer:

C

Explanation:

Gymnosperms generally refer to a group of terrestrial, seed-producing vascular plants whose means of reproduction is an exposed ovule known as a cone.

There are 6 divisions within the gymnosperms, including cycads, ginkgos, and pinus (conifers). Gymnosperms are generally non-flowering and produce needle-like leaves. Their species are usually woody or perennial shrubs/herbs

This is <u>unlike the angiosperms</u> that are usually classified into 2, including the eudicots and the monocots. The division is based on the number of cotyledons or seed leaves carried by the plants in the group during germination.

<em>The correction option here would, therefore, be C. </em>

<h2>Capillary Smooth Muscle Contraction</h2>

Explanation:

  • Blood flows through blood vessels, which form the closed system called the circulatory system. Like a system of roads, the circulatory system has its highways, back roads, and alleyways, which we call arteries, veins, and capillaries
  • Capillaries are the alleyways that extend and branch into every tissue of your body, ensuring that every cell has a blood supply. It is here, in the capillary beds, that your cells pick up oxygen and nutrients and drop off carbon dioxide and wastes
  • Muscles are composed of two major protein filaments: a thick filament composed of the protein myosin and a thin filament composed of the protein actin. Muscle contraction occurs when these filaments slide over one another in a series of repetitive events
  • All muscles contract as a result of interaction between special proteins within the myocytes. Skeletal, cardiac, and smooth muscle cells synthesize the contractile proteins actin and myosin, which are needed for muscular contraction
