Where does the external respiration take place in pets?
Answer:
In mammals (like cat and dog pets), external respiration takes place by the exchange of gases in the alveoli of the lungs
Explanation:
External respiration refers to the process of exchange of gases, i.e., oxygen (O2) and carbon dioxide (CO2), with the environment. In mammals like humans, dogs and cats, external respiration occurs in the millions of alveoli in the lungs and the capillaries that are located in the walls of the alveoli. This process (gas exchange) happens due to simple diffusion. The O2 is taken from the environment (by inhalation) and travels from the alveoli to the blood in the capillaries that surround the alveoli, while and CO2 diffuses from the blood capillaries to the alveoli (where this gas is exhaled).

There is likewise a pH version throughout special organelles, that can span from round 4.5to 8.0.
Water concentration:
Water molecules flow into and out of the cell at an identical fee, so the length stays constant. then a cell. This method of water attention is better within the cell than outside. Thus, water flows out of them, inflicting them to shrivel or maybe die.
Salt concentration:
Increase of the way of life medium NaCl attention from a hundred and 20 mm to 220 mm ended in a reduced boom fee and a boom in the content material of ribonucleic acid (RNA), protein, and lipide phosphate consistent. Cell quantity becomes likewise increased.

Choose the CORRECT statement about enzymes below.
Group of answer choices
Enzymes raise the activation energy needed in a chemical reaction
Enzymes slow down the rate of chemical reactions
Enzymes function best at specific pH and temperatures
Enzymes are carbohydrates and store short term energy
Answer:
Enzymes function best at specific pH and temperatures.
Explanation:
An enzyme can be defined as a biological catalyst that typically lowers the activation energy of a biological reaction. When the activation energy of a reaction is low, the rate of the reaction would be faster. Therefore, an enzyme speeds or catalyzes the rate of a reaction by lowering its activation energy.
Also, if the conditions are not optimal for an enzyme, it limits the ability of an enzyme to bind or be joined with its substrates.
Hence, the correct statement about enzymes is that enzymes function best at specific pH and temperatures. An increase in temperature increases or speeds up the rate of a reaction while low temperature limits or reduces the rate of a reaction. The optimal temperature for enzymes in the human body is around 37 degrees celsius.

What do you mean by traits?A trait is a specific characteristic of an individual. Traits can be determined by genes, environmental factors or by a combination of both.
Biological traits describe species' physiology, morphology, life history, and behavior, capturing both inter-specific interactions and the connections between species and their environment.
Autosomal dominant – where the gene for a trait or condition is dominant, and is on a non-sex chromosome. autosomal recessive – where the gene for a trait or condition is recessive, and is on a non-sex chromosome. X-linked dominant – where the gene for a trait or condition is dominant, and is on the X-chromosome.

In dividing cells, most of the cell's growth occurs during “_____”
Answer:
In dividing cells, most of the cell's growth occurs during interphase. 5. The mitotic spindle(s) is a cell structure consisting of microtubules, which forms during early mitosis and plays a role in cell division.
During interphase, DNA replication and cell expansion take place. During the mitotic phase, the cell divides and the DNA replication and cytoplasm are segregated.
What is the role of interphase in cell growth?The majority of a cell's time is spent in the phase known as interphase, during which it matures, copies its chromosomes, and prepares to divide. The cell then completes mitosis, leaves interphase, and divides to completion.
During the mitotic (M) phase, the cell splits into two new cells by dividing its cytoplasm and DNA into two sets.
Chromosomes will line up, split, and move into new daughter cells during mitosis. Interphase occurs between one mitotic (M) phase and the next because the prefix inter- signifies between.
Therefore, in dividing cells, most of the cell's growth occurs during interphase.

above.1. ________________________________ is what happens when depolarization of the atria cause the atria to go into atrial systole. Atrial pressure increases and more blood is forced into the ventricles via the AV valves.2. ________________________________ is the continued contraction of the ventricles that leads to the pressure inside the ventricles to build up and will thusforce open the semilunar valves and blood will be ejected out of the heart to the pulmonary and systemic circuits.3. _______________________________is the process that begins when both the atria and the ventricles are in diastole. Blood from the veins are returning to the heart and the pressure within the atria is higher than the ventricular pressure. Causing the AV valves to open and blood will passively fill into the ventricles. It is important to know that the semilunar valves are closed shut because they have higher pressure than both the left and right ventricle.
Answer:
1. Passive ventricular fillings.
2. Ventricular ejection.
3. Atrial contraction
Explanation:
In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
Diastole : in this stage, the ventricles is relaxed and would be filled with blood.
Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.
The following terms describe the physical or mechanical events with the correct phases of the cardiac cycle in mammals (human beings).
1. Passive ventricular fillings: is what happens when depolarization of the atria cause the atria to go into atrial systole. Atrial pressure increases and more blood is forced into the ventricles via the AV valves.
2. Ventricular ejection: is the continued contraction of the ventricles that leads to the pressure inside the ventricles to build up and will thus force open the semilunar valves and blood will be ejected out of the heart to the pulmonary and systemic circuits.
3. Atrial contraction: the process that begins when both the atria and the ventricles are in diastole. Blood from the veins are returning to the heart and the pressure within the atria is higher than the ventricular pressure. Causing the AV valves to open and blood will passively fill into the ventricles. It is important to know that the semilunar valves are closed shut because they have higher pressure than both the left and right ventricle.
