Explanation:
Excess Post Exercise Oxygen Consumption (EPOC) occurs, most often as a result of
a. High intensity interval training (HIIT)
b. Low intensity endurance training
C. Short term, moderate intensity strength training
d. ALL of the above
Next Previous
Answer: all of these exercise modes, but less likely with low intensity endurance training.
Explanation: exercise increases respiration requirement and therefore oxygen requirement. Energy stores (glycogen) are used first but with then the body needs to maintain energy production at an increased level. There is a limit to how quickly energy can be supplied from respiration and additional energy is generated anaerobically with the by product being lactic acid. An ‘oxygen debt’ is incurred because normal homeostasis requires the metabolism of lactic acid and energy for repair of any cellular damage, requiring oxygen consumption above what is required for normal resting metabolism. It is possible in elite athletes that during low intensity training they may be able to operate aerobically for an extended period.

How are land plants adapted to survive on land? What are the benefits of living on land rather than in water?
Answer:
Sample Response: Plants that are able to survive on land developed specialized vascular tissue such as xylem and phloem. This vascular tissue aids in the transport of water and other resources needed by the plant. Land plants also developed a cuticle, or waxy layer, to prevent water loss and seeds to protect young plants. The benefits of living on land are greater access to sunlight and less competition with other plants for resources.

Go to Set

Answer:
Viruses replicate only inside host cells.
Explanation:
Viruses are not used as evidence to support the cell theory because they are not considered a cell and cannot carry out vital life processes without getting into host cells.
According to the cell theory, the cell is the basic unit of life, all living organisms are made up of cells and cells arose from preexisting cells. A virus that is not in a host cell is just a piece of DNA/RNA surrounded by a protein coat and is not capable of carrying out any life process for it to be considered living.
Viruses are only able to reproduce and multiply when they get access to a living host. They use the genetic mechanisms of the host to replicate their DNA/RNA using the lytic or lysogenic cycle. Hence, they are not used to support the cell theory.
How could the pressure of a gas increase if temperature is constant?
Answer:
Gay Lussac's Law - states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature. If you heat a gas you give the molecules more energy so they move faster. This means more impacts on the walls of the container and an increase in the pressure.
Explanation:
Darwin studied actual birds on the Galapagos Islands instead of using a simulation, as you did in this lab. Studying natural selection in the field can be challenging. List at least three possible challenges Darwin might have faced.
Answer:
1. Darwin did not know how genetic material passed from one generation to the next because Mendel's laws of heredity had not yet been formulated
2. Finches have many phenotypic adaptations that can not be observed easily
3. Phenotypic traits are expected to evolve slowly, thereby taking many generations
Explanation:
In the Galapagos Islands, Darwin observed that there were many varieties of finches that showed variation in the size and shape of their beaks. Darwin determined that finches' beaks evolved in response to environmental changes (finches' beaks were different in different islands). Darwin had several challenges to make this discovery. First, Mendel's laws of heredity had not yet been formulated, thereby difficulting the analysis of quantitative traits (in this case, finches' beak) which are the result of the combined action of many genes and the environment. Second, finches (as well as all species) possess many phenotypic adaptations, thereby difficulting the study of single traits in an evolutionary context. Finally, phenotypic changes are gradual and therefore descendence with modification cannot be easily recognized by observation in the field.
Answer:
Traits other than beak type might affect natural selection.
It could take many generations to observe adaptions to a population.
The environment may be complex and hard to study.
Changes in the environment may occur faster or slower than changes to the birds
The birds may be interdependent with other organisms that may change, too.

Interphase is the part of the cell cycle during which these phases occur:
A. Growth 1, Synthesis, Growth 2
B. Growth 1, Synthesis, Growth 2, Mitosis
C. Growth 1 and Growth 2
D. Mitosis and Cytokinesis
Answer:
The correct answer is - A. Growth 1, Synthesis, Growth 2.
Explanation:
The cell cycle has three important phases Interphase, M -phase and cytokinesis. Interphase is the laongest phase of eukaryotic cell cycle. This phase shows no observational change in the cell, however, it collects nutrients, generates protein and replicates DNA and prepare the cell for the M- phase.
Interphase has 3 phases G1, S, and G2 phase. G1 phase is the phase that collects nutrients and increase the size of the cell for the cell division. S phase or synthesis phase is the phase takes maximum time in cell divivon and acompanied by protein generation, duplication of the genetic material. G2 phase is preparatory phase that prepeare the cell before the cell enter in the M - phase.

Under which condition is the speed of cellular chemical reactions within a cell most likely to decrease?
Answer:
The products of the reaction decreases
Explanation:
When the product are formed in a chemical reaction it leads to decrease in chemical reaction rate in a cell.
What Factors Affect the Speed of Chemical Reactions?Some chemical reactions are fast and some are slow due to presence of different factors.
The collision between the reactants specially at the reactive site of the molecule will be needed to complete the chemical reaction.
So larger the size of reactant slower be the reaction or even no reaction occur due to less collision.
The more surface area of the particle lead to more collision and faster the reaction.
More Concentration of chemical reactants lead to faster the reaction rate. Higher the pressure of the reactant lead to faster the reaction rate.
Increasing in temperature can also lead the molecules move faster, average kinetic energy of the molecule can also increases.

Which conclusion is best supported by the information?
A. The protist is an animal-like flagellate because it has
a flagellum.
B. The protist is a plant-like dinoflagellate because it
produces oxygen.
C. The protist is a plant-like dinoflagellate because it was
found in salt water.
D. The protist is an animal-like flagellate because it has
a nucleus.
Answer:
The correct answer is - B. The protist is a plant-like dinoflagellate because it produces oxygen.
Explanation:
Protists are a eukaryotic organism that is not a plant, animal, or fungi but definitely, they all arise from a common ancestor as these single-cell organisms with cell organelles like the nucleus. These shows similarities with all three kingdoms of the eukaryotes. It shows similarities with the animals they move and depend on the particle outside of their body for nutrition and energy.
Plants-like protists are the protist or dinoflagellates that present in freshwater, marine water perform photosynthesis and provide oxygen and glucose in the water for and maintain the oxygen in the water for the organism to breath.
Plant-like protists are essential to the ecosystem. They are the base of the marine food chain, and they produce oxygen through photosynthesis for animals to breathe

State a technology and
explain how it is used to
forecast a future event.
I don't really know your question but I will tell you what can be predicted.
But how can a technological forecast be made to contain probability dimensions in the same way other forecasts do? Most people think of a technology as a quite specific physical entity. They do not conceive of this entity as having the variable characteristics which would permit range forecasts or probability statements. To their minds, a precisely defined technology either will exist in a given situation, or it will not. And the forecaster must predict this exact event or else he is wrong. This misconception—which would place an impossible demand on any forecaster causes much of the confusion in discussions about technological forecasting.
