Answer:

The numbers after the arrows represent the number of the questions that should be considered next.

Explanation:

In the dichotomous key, the characteristics of the fish that will be considered must be carefully observed in order to develop a two-option system. Taking into account the fish features, the dilemmas generated will carry the number 1 (1a or 1b). Each option will present a description of the organism, and at the end of that choice there will be another number (arrow plus number), which belongs to the next feature described or questions asked about the organism to take into account to identify the taxonomic group. Depending on the option chosen, that question will lead to another question to be answered.

elixir [45]

Answer:

(Bone deposition),

(Bone resorption),

Remodeling

Periosteal ,

Nedosteal,

The compact bone,

Spongy bone.

Explanation:

The constant, dynamic process of continual addition of new bone tissue (bone deposition) and removal of old bone tissue (bone resorption) is a process called bone remodeling. This ongoing process occurs at both the periosteal (outer) and nedosteal (inner) surfaces of a bone.

It is estimated that about nedosteal of the adult human skeleton is replaced yearly. This process does not occur at the same rate everywhere in the skeleton. For example, the compact bone in our skeleton is replaced at a slower rate than the spongy bone.

Proteins are three dimensional molecules made of strands of amino acids (imagine a ball of string). There are 20 different amino

zlopas [31]

Answer:

A series of nonpolar amino acids would most likely be located in the interior region of the tridimensional molecule.

Explanation:

Proteins are formed by linearly arranged amino acids, each with a side chain: the R-group.

Of the 20 different amino acids that compose the proteins, about half of them -10- are non-polar. Their R-groups are not stable if they are in contact with water, meaning that non-polar amino acids are hydrophobic.

When proteins are synthesized, they acquire a three-dimensional structure that makes them more stable. Lineal polypeptides get folded and turn into a shape that makes them more stable in the environment and capable of accomplishing their biological role. When they are in an aqueous media, their bent shape leaves the hydrophilic R-groups in contact with water. The hydrophilic R-groups stick in the center of the polypeptide, facing the protein interior, and avoiding interaction with water.

PtichkaEL [24]

Answer:

Explanation:

The correct answer would be increasing heart rate to compensate for low cardiac output.

The negative feedback loop is the mechanism that is utilized in the maintenance of homeostasis. They work by opposing the processes that bring about a deviation away from setpoints, that is, the normal range of operation of physiological processes in the body.

For example, when the heart rate goes below the setpoint, the negative feedback loop swings into action through the sensor, the control center, and the effector to return the heart rate to the normal operating range.
