Greater force of contraction, volume of blood ejected, and cardiac output result in aerobically trained individuals with greater stroke volume compared to untrained individuals
What increases stroke volume?A greater force of contraction consequently increases the volume of blood ejected with each systole (Systolic Volume). Increasing the stroke volume also increases, as a consequence, the cardiac output (CO = VS x HR).
With this information, we can conclude that greater force of contraction, volume of blood ejected, and cardiac output result in aerobically trained individuals with greater stroke volume compared to untrained individuals

Answer:
hippocampusmedial temporal lobe1. Ms. L's symptoms include shortness of breath, a chronic cough productive of thick mucus,
and a "chest cold" of 2 months' duration. She was advised to quit smoking, a major cause of
lung irritation. These symptoms were caused in part by the obstruction of groups of alveoli
by mucous plugs. Ms. L was told that the mucus is not moving normally out of her airways
because the toxins in cigarette smoke paralyze small cell extensions that beat to create an up-
ward current. These extensions are called
The small cell extensions that beat to create an up-ward current are called microvilli.
What are microvilli?Microvilli are small extensions which are found on the surface of the alveoli of the lungs.
The microvilli play an important role in the lungs as the help to remove particles and mucus that may obstruct the lungs as a result of the upward current they create in the lungs from their beating motion.
Therefore, the paralyzed small cell extensions that beat to create an up-ward current are called microvilli.

The release of greenhouse gases from one state can enter another state due to atmospheric circulation. If there is a problem between states, what do you think would be the best way to handle this problem???
Due to atmospheric circulation, the greenhouse gases can enter from one state to another state. These changes are caused by extra heat in the climate system due to the addition of greenhouse gases to the atmosphere.
What are the ways to handle greenhouse effect?The Earth's radiated energy is trapped by greenhouse gases such carbon dioxide, methane, nitrous oxide, and some manmade compounds, which keeps heat in the atmosphere.
The best way to handle this problem are:

Which function involves the circulatory system working with the respiratory system?
A. Lowering body temperature
B. Enabling cellular respiration
C. Stopping bacterial infection
D. Maintaining liver function
The function involves the circulatory system working with the respiratory system is Enabling cellular respiration. Thus, option "B" is correct.
What are circulatory and Respiratory system?Respiratory system is a set of organs which help in the exchange of gases in the body. They bring oxygen from outside into the body and release carbon dioxide from inside the body to the outside world. The exchange of the gases takes place at the alveolar site (or gills in aquatic animals).
The circulatory system then carries this oxygen (mixed in blood) from gas exchange site to all the cells of the body. In addition, it also brings carbon dioxide (waste product of cellular respiration) from all the cells to the gas exchange site (respiratory system).
Thus, option "B" is correct.

What are Interphase, prophase I, metaphase I, anaphase I, telophase I, prophase Il, metaphase II, anaphase II, telophase Il in meiosis.
The stages of meiosis 1 and meiosis 2 is discussed below:
What is meiosis?Eukaryotic cells (plants, animals, and fungi) reproduce sexually through a process called meiosis. Chromosome reduction is the process by which haploid cells are created from diploid cells, which are cells with two complete and identical sets of chromosomes.
The number of chromosomes in each cell is halved during meiosis I, which starts with one diploid parent cell and ends with two haploid daughter cells.
Maintaining the number of chromosomes in each cell, meiosis II begins with two haploid parent cells and finishes with four haploid daughter cells. Before meiosis II, homologous pairs of cells divide into chromosomes while in meiosis I.
These chromosomes are further divided into sister chromatids during meiosis II. Meiosis II does not include genetic material crossing across or recombining between chromosomal pairs, whereas meiosis I do.
This happen in the prophase contains five subphases and is lengthy and complex during meiosis I. The equatorial plane in meiosis II is aligned 90 degrees differently than in meiosis.
Therefore interphase1, prophase 1, metaphase 1, anaphase, and telophase 1 are the stages of meiosis 1 and prophase Il, metaphase II, anaphase II, and telophase Il in meiosis 2.

Describe artificial selection, and explain how it is different from natural selection.
Answer:
Starting with natural selection, the most robust and most intelligent animals survive over the weakest. The weak animals eventually die off because they can't keep up with nature. Artificial selection isn't natural; certain species are being targeted on purpose and decide whether to stay alive or not. At this point, it is not at all about whether the species can survive or not because it's most likely being protected.

Based on the reactivity of catalase in the enzyme concentration lab, do your results in testing enzyme concentration support your hypothesis?
There were more substrate molecules to bond with the active site of the catalase enzyme as the substrate concentration increased.
What is an enzyme?The enzymes are the chemical molecules that alter the chemical reaction when added in a specific amount, it either increases the reaction, or decrease it.
There were more substrate molecules to bond with the active site of the catalase enzyme as the substrate concentration increased.
Because the substrate concentration increased each time, there was a greater chance that the substrate would bind to the active site and carry out the reaction.
Thus, this way the enzyme concentration affects the reactivity.
