Cardiac output is the amount of blood pumped by the heart in one minute. Which of these will increase cardiac output?
decreased blood volume
increased physical activity
decreased metabolic activity
increased resistance in blood vessels
Answers
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.
Answers
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!
Best of luck, and feel free to ask for any clarification.

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
Answers
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.

A Varroa mite attaches to a honeybee and feeds on the bee's blood. However, the mite does not cause the bee to die. Which best describes the relationship between the mite and the bee?
A. Predation
B. Mutualism
C. Cooperation
D. Parasitism
Answers
Answer:
Parasitism
Explanation:
There is no mutual relationship (also meaning no cooperation, which I do not think is a type of relationship), the mite isn't "eating" the honeybee, so not predation. Therefore, parasitism, when one creature benefits at the expense of the other creature.
Which is a pollutant associated with high-tech gadgets in landfills?
A. Carbon Dioxide
B. Oxygen
C. Lead
D. Nitrogen
Answers
The pollutants associated with the high tech-gadgets or e-waste include mercury, lead, cadmium, etc. So the correct answer is option C.
An electronic device that has reached the end of its usable life cycle is called as the electronic waste or the e-waste. The electronic waste contains a lot of toxic compounds inside them and should be handled carefully because this e-waste releases the toxic pollutants in the environment which can cause air pollution and also has an impact on respiratory health.
Burning of e-waste can release fine particles (pollutants) into the enviroment which can cause chronic diseases and cancers as well.

why is the study of fish and fish farming important in the study of animal science?
Answers
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:
- Eijiro <3
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.

Why are stone tools found on their own?
Answers
Stone tools are found on their own because they do not decompose and stay as they are.
What is the importance of stone tools in human history?In the broadest definition, a stone tool is any tool that is manufactured totally or mostly of stone.
Some stone tools were used for chopping fruits and roots as well as for cutting flesh and bone, removing bark from trees, and cutting into hides, or animal skins. A few of them served as handles. Some were used to create hunting spears and arrows.
Early human creations, such as stone tools and other artifacts, provide information on how people lived, interacted with their environment, and changed over time. Thousands of archaeological sites have been investigated, excavated, and dated during the last 2.6 million years.

If chemical signals in the cytoplasm control the progression of a cell to the M phase of the cell cycle, then fusion of a cell in G1 with a cell in early M phase would most likely result in the Group of answer choices replication of chromosomes only in the G1 cell transfer of organelles from the G1 cell to the cell in the M phase condensation of chromatin in preparation of nuclear division in both cells exiting of both cells from the cell cycle and into the G0 phase
Answers
Answer:
condensation of chromatin in preparation of nuclear division in both cells
Explanation:
Mitosis, as a type of cell division, is divided into Interphase and the Mitotic phase. The interphase further comprises of G1, S and G2 phases while the mitotic phase consists of mitosis and cytokinesis.
Mitosis is a form of nuclear division i.e. separation of genetic material (chromosome). According to this question, chemical signals in the cytoplasm control the progression of a cell to the M phase of the cell cycle.
Since what occurs in the M phase of the cell cycle is nuclear division, then fusion of a cell in G1 with a cell in early M phase would most likely result in "the CONDENSATION OF CHROMATIN in preparation of NUCLEAR DIVISION in both cells".
