A marathon runner is running a race. During the race the marathon runners heart rate and breathing increases. Which of the following explains why the marathon runners' body is responding in this way?

Answers

Answer 1

Answer:

Warmer temperatures increase your heart rate. In addition to pumping more blood to the muscles, your heart also transports more blood to the skin in order to cool it. Increased demand causes your heart to beat faster -- anywhere from 20 to 40 beats per minute higher than normal.

1. Identify one population of organisms shown in the food web, other than rabbits or mice, that would likely be affected by the introduction of snowy owls AND explain why their population would be affected.

2. State which level, a, B, or C, contains the least total available energy. Support your answer.

Answers

Answer:

The population if snakes will decline because there will be competition between snakes and snow owls. The snow owls will eat the mice, but if there's only a small population of mice. Only a few snakes will eat, other snakes will die of starvation. There will be competition between snow owls, hawks and mountain lions, but they have other sources of food, unlike snakes.

Level C contains the least amount of energy. This is because each level gets less and less energy per meal, beacuse energy is released by each organism.

Malaria, a type of parasite, infects 500 million people each year by infecting the red blood cells of its host. The virus, HIV, that causes AIDS, reports 50,000 newly infected persons. Which statement best differentiates the pathogens, parasites and viruses?
options: Although both rely on other living organisms to survive, viruses are usually beneficial.

Although both rely on other living organisms to survive, parasites feed on the host organism.

Although both are living organisms, viruses break down dead plants and animals that other organisms use.

Although both are living organisms, parasites depend on the cells of living things to reproduce.

Answers

Answer:

The second statement clearly differentiates the pathogens best. Parasites feed on living host while viruses depend on the cells of other organisms to survive and reproduce as they cannot function outside a living host.

Although both rely on other living organisms to survive, parasites feed on the host organism. The correct option is B.

What are parasites?

A parasite is an organism that lives on or in the host and obtains its food from or at the expense of the host.

Protozoa, helminths, and ectoparasites are the three main types of parasites that can cause disease in humans.

They frequently go unnoticed because they have few symptoms. However, these infections frequently result in serious illnesses such as seizures, blindness, heart failure, and even death.

A parasitic relationship takes place when one lifeform, the parasite, feeds on another organism, the host, causing harm and possibly death.

The parasite lives on or in the host's body. Tapeworms, fleas, as well as barnacles are examples of parasites.

Thus, the correct option is B.

AZT is a drug that is commonly used to fight HIV infection. The active component of AZT is a nitrogenous base that mimics thymine. Normal nucleotides CANNOT covalently bond to the thymine mimic. HIV's reverse transcriptase enzyme will use the thymine mimic instead of using thymine, whereas our DNA polymerase will not make this mistake. What is the most likely explanation for how AZT prevents HIV replication

Answers

Answer:

AZT works by selectively inhibiting HIV's reverse transcriptase, the enzyme that the virus uses to make a DNA copy of its RNA. Reverse transcription is necessary for production of HIV's double-stranded DNA, which would be subsequently integrated into the genetic material of the infected cell to produce its proteins. All reverse transcriptase inhibitors are analogues of the naturally occurring deoxynucleotides needed to synthesize the viral DNA and they compete with the natural deoxynucleotides for incorporation into the growing viral DNA chain.

Answer:

I can't definitively answer this because I don't know the experiment, but I can help.

Explanation:

The "control group" of an experiment is like a dry simulation, where there is no variables changed across all the different trials you do. This is different from a dependent variable or an independent variable. Using your newfound knowledge of what a control group is you can automatically cross off the last option.

Since I cannot see what your experiment was I can't give you which of the top 3 answers it is however. You need to look at which one has no change.

Grassland biome has a cold harsh climate and short growing season.

What is Grassland?

Grasslands can be found in regions with regular rainfall levels that are insufficient for a forest to thrive but not so low that a desert develops. Indeed, meadows are frequently found between deserts and woods. Grasslands cover anywhere from 20 to 40% of the planet's geographical area, depending on how they are characterized.

They exist on every continent, with the exception of Antarctica, and are often open and flat, making them susceptible to pressure from burgeoning human populations.

Agriculture, excessive grazing, invasive species, unreported hunting, and climate change are some of the threats to natural grasslands and the wildlife that inhabits them.

Therefore, Grassland biome has a cold harsh climate and short growing season.
