Answer: The true descriptions regarding muscles are; Cardiac muscles and skeletal muscles are striated, heart (cardiac) and digestive (smooth) muscles are involuntary muscles, cardiac muscles work to pump blood. Skeletal muscles are the muscles that attach to the bones and their main function i contracting to facilitate movement of our skeletons. Smooth muscle are found in walls of hollow organs such as the stomach and are stimulated by involuntary action. While the cardiac muscles are found solely in the walls of the heart, they are highly specialized and under the control of the autonomic nervous system.
Explanation:
Not my work but i found this on brainly lol
The course of action is performing a series of 5 back blows by kneeling to the side and just behind the 15 month old. <span> Place your arm across the chest for support. Bend the child over at the waist in order that the upper body is in ground parallel . exhibit five separate back blows in between the child's shoulder blades with assistance of the heel of your hand, then apply </span>5 chest thrusts or the <span>Heimlich maneuver</span>. This a first aid for choking and the signs and symptoms exhibited by the 15 month old is choking.
The human egg cell is the largest cell in the human body, measuring approximately 0.13 mm in diameter.
Its size is 10 times the diameter and 1000 times the volume of most other human body cells. It can actually be seen without the aid of a microscope if one observes keenly.
Unlike ordinary body cells which have a cell membrane, the egg has a special outer coat called zona pellucida which is made up of a jelly-like extracellular matrix composed mainly of glycoproteins.
Answer:
The correct choice is ''ion electrochemical gradients''.
Diffusion of ions across membranes through specific ion channels is driven by <u>ion electrochemical gradients</u>.
Explanation:
An electrochemical gradient can be considered as that electrical (electrostatic pressure) and chemical (diffusion) force that determine the movement of molecules and ions across the membrane. This electrochemical gradient, in addition to causing movement of substances through cell membranes, is also a type of potential energy available for the performance of different cellular activities, potential energy called membrane potential.
Answer:
B. Water molecules bond with other water as they are transported throughout a plant.
