Answer:

The correct combination for the 3 key properties is:

a. must allow faithful replication.

b. must have informational content.

c. must be able to change on rare occasions.

Explanation:

Since every cell in one particular body essentially contains the same DNA, it has to be copied accurately every time a cell divides. The information that the DNA codes for is the proteins that get translated and accounts for every feature that organism will have. These rare changes are known as mutations and they are critical to introducing variation in the species and allowing them to evolve in response to environmental stimulation.

Hope that answers the question, have a great day!

Which of these organs is found in the excretory system?
Paraphin [41]

The urinary system is the main excretory system of the body after the gastrointestinal tract (large intestine) and lungs, In these questions it is necessary to prioritize the urinary tract.

The right answer is D. Bladder

The bladder belongs to the urinary excretory system.

The bladder receives the urine produced by the kidneys via the ureter and has the function of storing it before its elimination during urination through the urethra. The muscles surrounding the bladder help to prevent urine reflux to the ureter.


The right answer is C. Kidneys

The main purpose of the renal excretory system is to eliminate nitrogenous wastes while maintaining homeostasis, all through the formation of urine.

The kidney has a secretory function (filtration of blood in the glomeruli) and excretory from the pyelon (triangle based on the renal hilum) origin of the ureter. We speak of pyelo-ureteral junction. Each kidney contains about 1 million nephron.

What are the three general types of questions that perception helps us answer regarding our environment?
Lisa [10]

Explanation:

Because we always seek to make sense of any perceived stimulus to better understand the reality that surrounds us and act before it. Through perception we process information from the senses, with which the brain builds and tries to give meaning to those stimuli that reach it. However, each person captures, selects and organizes sensory stimuli differently and, therefore, arrives at different interpretations and responses when solving a problem, in which memory and experience also form a fundamental role. Thus, differences between perceptions help explain how people interpret the environment and why they behave differently in the same situation. For example, when we recognize a specific object, an action can be initiated, in which a motor activity is propitiated in response to that recognition, and which can be different in each person.

The processes of a neuron that usually receive signals from other neurons are called.
Marina86 [1]

Dendrites are the processes of a neuron that receive signals from other neurons. Dendrites receive signals from other neurons via specialized junctions known as synapses.

<h3>What is Dendrites?</h3>
  • The receiving end of a neuron is referred to as a dendrite. The ability of a neuron to generate an action potential is determined by the synaptic impulses exchanged between its axons and dendrites.
  • Cell Body is in charge of controlling the activities of neurons. Myelin protects the axon while also speeding up and simplifying message transmission.
  • Other neurons send messages to dendrites. Axons carry signals from the cell body to neighboring neurons' dendrites. It normally receives incoming impulses from other neurons via its dendrites.
  • The signal sent to other neurons travels along the axon. Despite having millions of dendrites, a neuron only has one axon. Within a neuron's fourth special part
