Answer:
In the final decades of the 19th century, Koch conclusively established that a particular germ could cause a specific disease. He did this by experimentation with anthrax. Using a microscope, Koch examined the blood of cows that had died of anthrax. He observed rod-shaped bacteria and suspected they caused anthrax.

Answer:
An outbreak of a disease that infects squirrels in the park.
Explanation:
All the other answer choices would increase the population of squirrels. For the first option, more trees = more habitats = more squirrels to live in. For the second option, less hawks = less predators = more squirrels that will survive. For the third option, heavy rain = more acorns = more food for more squirrels.
Only the last option would limit the growth of a population of squirrels since diseases kill organisms in a population.

fluorinated gas
nitrous oxide
methane
answer:
-- b), fluorinated gas
hope this helps.
The greenhouse gas that is produced by commercial refrigeration and air conditioning systems is fluorinated gas.
WHAT IS GREENHOUSE GAS?A greenhouse gas is a gas that has the ability to trap and release heat energy into the atmosphere.
Greenhouse gases are the major causes of global warming, which is the rise in the global atmospheric temperature.
Examples of greenhouse gases are carbon dioxide, methane, fluorinated gas etc. Therefore, greenhouse gas that is produced by commercial refrigeration and air conditioning systems is fluorinated gas.

Bird species from temperate regions must cope with relatively short breeding seasons. A study examined the relationship between blood testosterone level (ng/ml) and the duration of the egg-laying period (months) in temperate bird species. The scatterplot below displays this relationship, after taking the logarithm of each variable. A plausible value for the correlation between the logarithm of egg-laying duration and the logarithm of testosterone level is
Answer:
The answer is "-0.4".
Explanation:
In that situation, the value of the possible correlations between the egg-laying logarithm as well as the testosterone level logarithm is equal to 4 It value is equal to the percentage 4=-0.4.

The muscle fiber (cell) is indicated by
Label A
Label B
Label C
Label D
Answer:
Hope it helps
Explanation:
The label A represents mitochondria.
The mitochondria are also called the powerhouse of the cell which converts glucose to energy-rich molecules of ATP.
Label B represents the nucleus.
The nucleus contains the genetic material or DNA, RNA, nucleolus, chromatin fibers, and proteins. It contains the chromosomes which control the hereditary characteristics.
Label C represents the lysosome.
Lysosomes contain digestive juices which break down large cell parts and large molecules and help in intracellular digestion.
Label D represents rough endoplasmic reticulum having ribosomes.
The rough endoplasmic reticulum provides a surface for protein synthesis. It is also used to transport cellular contents from one cell to another.

How many years does a snake live and how many times does it change its skin without pictures please and without links
Answer:
9 years
Explanation:
Boa constrictor: 30 years
Boa constrictors are native to North, Central, and South America, mainly dwelling in rainforests. The lifespan for the large, heavy-bodied snake averages about 20 years in the wild, but living in captivity can increase that by 10 to 15 years.
Answer: Some types of snake can live for 2-3 decades, such as the boa constrictor, whereas others, such as garter snakes, will be fortunate to reach 10 years of age. On averge a snack changes its skin up to 2-4 times a year.

5) It is said that the hottest layer of the earth
is the core (outer core and the inner core)
and that is where metal is found. Why
can't metal melt in the core?
Answer:
please give me brainlist and follow
Explanation:
The churning metal of the outer core creates and sustains Earth's magnetic field. The hottest part of the core is actually the Bullen discontinuity, where temperatures reach 6,000° Celsius (10,800° Fahrenheit)—as hot as the surface of the sun. The inner core is a hot, dense ball of (mostly) iron.

Difference between palisade cell and fungal cell
Answer:
Explanation:
Plantae and Fungi are two of the three main kingdoms in the domain Eukaryote (the third group is Animalia, which includes you and me).
Many fungi grow in a way that’s similar to plants. They inhabit similar ecosystems and may even form symbiotic relationships together. Mycorrhizae are fungi that grow on the roots of plants, helping the plants take up nutrients in the soil while the plant provides the fungus with sugar. Of course, most fungi don’t look much like plants.
But the differences between fungi and plants are more than just skin (or bark) deep. While mushrooms often inhabit similar ecosystems to plants, molds and yeasts are even more different from plants!
Looking at a plant cell and a fungi cell under a microscope will reveal some interesting similarities and differences.

Therefore, human disruption of the carbon cycle can be said to have been implicated in climate change.
Describe how brine pools function
Explanation:
Brine pools are sometimes called sea floor "lakes" because the dense brine does not easily mix with overlying seawater. The high salinity raises the density of the brine, which creates a distinct surface and shoreline for the pool. When submarines dive into brine pools, they float on the brine surface due to the high density
