Single ring structures known as pyrimidines
Answer:
All manifestations of mitosis noted so far occur in animal and plant cells, and there are two differences between them. Astral and anastral mitosis: In astral mitosis, the centrioles of the animal cell are involved in the fibers of the aster. Anastral mitosis, on the other hand, is when we don't find both centrioles and asters in plants.
The other difference is Cytokinesis: In animal cells, since there is no cell wall, there is a strangulation of the plasma membrane, and cytokinesis is called centripetal. In plant cells, due to the presence of a cell wall, it is not possible to have a strangulation division. What occurs is an agglomeration in the equatorial region of vesicles originated from the Golgi complex. These vesicles unite, forming a thin strip, separating the daughter cells. After this process, the synthesis of the cell walls extends from the center to the periphery, under the name of the centrifugal division.
<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
Answer:
weather rock Explanation: its right on quizlet
Answer:
The correct answer is C. It utilizes energy
Explanation:
The properties of a living organism is that living organism can grow, reproduce, respire, homeostasis, respond, adapt and perform metabolic activities. Living organisms can be microscopic or macroscopic. DNA can be present in the organism who died so the presence of DNA does not determine that the organism is living.
So one of the properties of a living organism is that it perform metabolic activities to utilize energy for growth and development. Therefore if the microscopic structure utilizes energy than it will considered to be a living organism.
