decreased blood volume
increased physical activity
decreased metabolic activity
increased resistance in blood vessels
Physical activity will increase cardiac output. Therefore, the correct option is "B".
What is cardiac output?Cardiac output is related to the heart's health. It tells the amount of blood pumping in and out of the chambers of the heart. This mechanism helps in circulation of the blood throughout the body. The blood can be oxygenated and deoxygenated. The circulation of blood to the vital organs and the main organ brain is circulated through this process.
The calculation of the cardiac output is oxygen consumption in ml per minute is divided by the oxygen concentration in arterial blood and minus oxygen concentration in venous blood in the body.
Therefore, the calculation of the cardiac output helps in the identification of the heart's health.

In the early 1900s, the Florida panther was found all over Florida. By 1967, the population had dropped to only 30 panthers statewide, and the panther was listed as an endangered species. What is the most likely reason for the decline in the panther population?
A. Florida's climate changed dramatically.
B. Panthers were hunted by humans for many years.
C. The panthers moved north into Georgia and South Carolina.
D. Alligators stopped eating other animals and started eating panthers.
Answer:
B.
Explanation:
Florida's climate itself hasn't particularly changed a bunch, but in the 20th century the population of Florida has increased. Plus D and C are easy to rule out. The easiest explanation for the panther's decline is the fragmentation of their habitat, and human interaction with the environment, not hunting per se. Good news is that the Florida panther's population has gone up to over 100!

Animal and Plant Cell Organelles Use the drop-down menus to determine where these organelles can be found. Ribosome Endoplasmic reticulum Golgi apparatus Cell wall Vacuoles Lysosomes Mitochondria Cell membrane Cytoplasm Chloroplasts
Answer:
Animal Cell:Ribosome, Endoplasmic reticulum, Golgi apparatus, small Vacuoles, Lysosomes, Mitochondria, Cell membrane, Cytoplasm.
Plant Cell:Ribosome, Endoplasmic reticulum, Golgi apparatus, Cell wall, Big Vacuole, Lysosomes, Mitochondria, Cell membrane, Cytoplasm, Chloroplasts.
Explanation:
Animal Cells Vegetable Cells
Cell wall NO YES
Vacuoles YES, Small and more than ones YES, Only one and big
Chloroplast NO YES
Plasmatic membrane YES YES
Mitochondria YES YES
Lysosomes YES YES
Endoplasmic reticulum YES YES
Golgi apparatus YES YES
Cytoplasm YES YES
Ribosome YES YES
Both the animal and plant cells are eukaryotic. They carry their genetic material in the nucleus and mitochondria. Organelles are located in the cytosol, and both of them are surrounded by a protector cell membrane.
However, they have some differences:
Cell wall: A rigid structure that provides support and protection.
Animal cells do not have a cell wall. They are only surrounded by the cell membrane, which is flexible, so they can adopt different shapes. Plant cells have a wall, so their shape is usually prismatic and regular. The cell wall is composed mainly of cellulose.Chloroplast: these are organelles that accumulate chlorophyll.
Animal cells do not have chloroplasts because they do not photosynthesize. Plant cells have chloroplasts, and they are in charge of the photosynthesis process that allows plants to release oxygen. These organelles use solar light as the source of energy.Vacuoles:
Animal cells have many and small vacuoles whose function is to store water, ions, and waste intracellular substances. Plant cells have a unique big-sized vacuole that might occupy almost 90% of the cell. Their principal function is to store water and keep the turgidity. When the vacuole gets empty, the plant loses rigidity.Other differences are:
The animal cell has centrioles, while the vegetable cell does not.
Plasmodium, chromoplasts, and glyoxysomes are present in the vegetable cell but not in the animal cell.
why is the study of fish and fish farming important in the study of animal science?
Answer:
Such physiological research will offer a wealth of information that can help in fish survival and management. This include how fish respond to and withstand a variety of environmental factors, as well as how fish bodies and internal processes evolve over time (including smoltification and reproduction).
Fish are more effective at converting feed into body protein than cattle or chickens. It's a lot more economical, which means the fish industries can produce more food with less feed. Since less food and resources are used in the processing of food, the process is therefore less expensive.
Explanation:

The study of fish and fish farming is important in the study of animal science in various aspects. Some of them are given below:
Fish is a rich source of protein.High economic value.Better productivity.Less expensive. What do you mean by Fish farming?Fish farming may be defined as a form of aquaculture in which fish are raised in enclosures to be sold as food.
Fish is an organism that is known as the king of aquatic habitats. Being this property the study of fish and fish farming leads to more advancement in its gene sequence, amount of protein content, and even a rough amount of its cost. On the other hand, it is also a chief source of food that contains significant protein.
