Answer: Nervous system, skeletal system, muscular system. The nervous system control the muscles and the skeletal system helps to support those muscles.
Explanation:
The nervous system consists of a set of cells specialized in conducting electrical and chemical signals, called neurons, and glial cells that are supportive. The nervous system picks up external stimuli from the environment or signals from the organism itself (internal stimuli), and this information is transmitted by nerves to the brain, where everything is processed and a signal is emitted that causes the contraction of certain muscles.
The nervous system is divided into central and peripheral systems. The central nervous system comprises the spinal cord and brain, while the peripheral nervous system comprises the nerves that connect the central nervous system to the body. Within the peripheral nervous system, there is a sensory (afferent) nervous system responsible for incorporating information from receptors (such as the eyes, the skin for touch, etc.), and a motor (efferent) system that carries the information to the muscles.
From the functional point of view, it is also differentiated into somatic and autonomic system. The somatic nervous system consists of neurons that control voluntary actions, while the autonomic nervous system is responsible for involuntary functions. And within the latter group are included the sympathetic nervous system (which is activated in situations of danger to stimulate many organ functions that cause a rapid response), the parasympathetic (which is involved in the regulation of several organs and its action is opposite to that of the sympathetic nervous system) and the enteric nervous system in the gastrointestinal tract.
The muscular system is a set of muscles that can be controlled voluntarily, if we refer to skeletal muscles. Their main function is mobility, an action that takes place when stimuli from the nervous system provoke the contraction of the muscle fibers. There are three types of muscle tissue: skeletal, smooth and cardiac, and all of them are able to contract but they differ in certain characteristics, location and the way in which the contraction is regulated, which can be voluntary or involuntary.
Muscle tissue receives electrical impulses from the nervous system and responds to them by generating a contraction movement. The neuromuscular junction plate is the connection established between a motor neuron and a muscle, by means of which the neuron transmits electrical impulses to the muscle fiber and between them there is a space called synaptic cleft. When a nerve impulse called action potential travels through the axon of a motor neuron, the neurotransmitter acetylcholine is released into the synaptic cleft, which binds to the muscle cell membrane and causes it to alter its membrane potential causing a depolarization that triggers contraction.
Finally, the skeletal system consists of a rigid structure formed by bones, and has several functions such as mechanical support, maintenance of posture, makes possible the bipedal position and protection of vital organs. The joints between two adjacent bones, called articulations, make muscular movements possible. In addition, the bones serve as insertion sites for the tendons of the muscles, which allow movement that is controlled by the nervous system and carried out mainly by the muscular system.
So, the nervous system control the muscles and the skeletal system helps to support those muscles.

if the mass extinction event that had wiped out the dinosaurs had not occurred, could dinosaurs rather than mammals have evolved into an intelligent organism resembling modern day humans ?
Answer:
If the mass extinction even that had wiped out the dinosaurs had not occurred, dinosaurs would've evolved. Though maybe not into organisms that resemble modern-day humans, they would've become better versions of themself. However, some of them might've died out naturally due to climate change and other natural disasters.
If the mass extinction event had wiped out the dinosaurs and not occurred. The dinosaurs would not have been converted into an intelligent organism like humans, because evolution may be bad or good, nothing is always evolution that results in good traits.
What are dinosaurs?Dinosaurs are extinct reptiles, that were very big, and they were both herbivorous and carnivorous. These animals were present 56 million years ago. They got extinct because of an unknown reason, but scientists say that they got extinct due to the falling of meteorites.
If dinosaurs had not been extinct, they would be evolved according to the changes in the environment. They would not be converted into human intelligence.
Therefore, since evolution can be either positive or negative, there is no guarantee that it will always produce positive features in organisms, the dinosaurs would not have evolved into sophisticated beings like humans.

What characteristics of the blood cell helps it to pass freely through blood capillaries
Answer:
The cell is flexible and assumes a bell shape as it passes through extremely small blood vessels. It is covered with a membrane composed of lipids and proteins, lacks a nucleus, and contains hemoglobin—a red iron-rich protein that binds oxygen.
Answer:
The cell is flexible and takes the form of a bell through extremely small blood vessels. It is clothed in a fluid and protein-membrane, lacks a nucleus, and has hemoglobin—a rich red iron protein that binds oxygen.
Explanation:
The hemoglobin in red blood cells contains four iron-binding heme groups.
Heme groups of hemoglobin are binding on oxygen. Each molecule of hemoglobin can bind up to four molecules of oxygen.
Hemoglobin has a cooperative binding affinity to oxygen. The saturation of the molecule increases by oxygen. The connection of the initial molecule of oxygen affects the form of the other binding sites. For additional oxygen molecules, the binding becomes more favorable.
The four iron-binding hemo-groups are located in each hemoglobin molecule. Hemoglobin is known as oxygen-bound hemoglobin.
The reversible carbon dioxide is transformed into the carbonic acid reaction by the enzyme carbenoid anhydrase by the Red blood cells altering the blood PH.
Instead of being converted to carbonic acid, pH is controlled by carbon dioxide bindings to hemoglobin.
CO2: The enzyme found in RBCs catalyzing the reaction between carbonic anhydrase and carbonate dioxide and water.
Co-operative binding: When a first molecule is binding to a binding location, the same molecule is favored for the remainder of the binding locations by means of increased binding affinity.
