What is the study of fish known as in biology?​
klio [65]

Answer:

The study of fish is called Ichthyology.

Explanation:

Fish specimens are identified in the field by ichthyologists. Ichthyology is the field of study that deals with fishes. Taxonomy (classification and the description of new species) and biogeography are the two main areas of focus for museum ichthyologists (patterns of distribution).

Ichthyology is the field of study that deals with fishes. Taxonomy (classification and the description of new species) and biogeography are the two main areas of focus for museum ichthyologists (patterns of distribution). Large reference collections of preserved specimens are kept in museums as a permanent resource for present-day researchers as well as for future ones.

Elza [17]

"Dave", the feathered lizard fossil is thought of as a(n)<u> </u><u>homologous</u> species, or an organism that may represent a common ancestor shared by different but related lineages of organisms.

<h3>What is homologous evolution?</h3>

Homologous evolution is similarity of the structure, physiology, or development of different species of organisms based upon their descent from a common evolutionary ancestor.

Homologous structures include the human arm, a bird or bat's wing, a dog's leg, a dolphin or whale's flipper, and the wing of a bird or a bat. They are distinct and serve different purposes, although they are comparable and have similar characteristics. They are regarded as homologous structures because their underlying anatomies are comparable.

DanielleElmas [232]

B. Being new to the country, it is safer for Sarah to take precautions until she gets acclimated

I believe this is the answer as the other answers take too many assumptions as the question doesn't explicitely state that Sarah has skin problems.

Correctly identify each of these definitions or examples as either depolarization or hyperpolarization of the plasma membrane. 1
natulia [17]

Answer:

  1. hyperpolarization
  2. depolarization
  3. hyperpolarization
  4. depolarization
  5. hyperpolarization
  6. depolarization
  7. depolarization

Explanation:

The resting membrane potential is balanced by ion leakage and ion pumping, to get an electrical signal started the membrane potential has to lose its balance. This starts with a membrane channel opening for Na+ since Na+ concentration is higher outside the cell, ions will rush into the cell. This will change the relative voltage inside the cell. The resting potential has a voltage of -70 mV, the sodium cation entering the cell cause it to become less negative. <em>This is known as depolarization.</em>

The concentration gradient for Na+ will continue to enter the cell making the voltage to become positive reaching +30 mV. At the same time, this happens, other voltage-gated channels are also opening, a concentration gradient acts on K+, as well, as it leaves the cell, it takes a positive charge with it making the membrane potential to move back to its resting voltage of -70 mV. <em>This is called repolarization. </em>

For potassium ions to reach equilibrium the membrane voltage needs to be below -70 mV, this leads to a period of <em>hyperpolarization</em> that occurs while the K+ channels are open.

I annexed an image that illustrates this action potential process.

<em>Considering the information given during depolarization there's an increase in the number of sodium leak channels (7) making the inside of the cell more positive (2) increase in the membrane potential (4), this also implies a decrease in the extracellular concentration of potassium (6)</em>

<em>Meanwhile, during hyperpolarization an increase in the extracellular concentration of potassium (3) decreases the membrane potential (1) making the inside of the cell more negative (5).</em>

I hope you find this information useful and interesting! Good luck!<em>       </em>

When asked to analyze a sample of marine life, you notice the animal has an incomplete digestive tract, stinging cells, and swim
lianna [129]

Answer:

The correct option is;

True

Explanation:

The digestive system of Cnidarians is incomplete having only one single opening which is the gastrovascular cavity the representing the anus and the mouthof the Cnidarians

The hollow body of the Cnidarian polyp which allows water through has tentacles at the top bearing cells meant for stinging

A prey caught by the tentacles is drawn in to the mouth and ingested

The Cnidarians are able to attach to surface due to their attachment adapted lower end

The correct option is therefore true.
