Answer:
viral infections
Explanation:
Pneumonia is a lung disease characterized by inflammation of the airspaces in the lungs, most commonly due to an infection. Pneumonia may be caused by viral infections, bacterial infections, or fungi; less frequently by other causes. The most common bacterial type that causes pneumonia is Streptococcus pneumoniae.
How do limiting factors impact local ecosystems?
A)Limiting Factors prevent populations in ecosystems form growing any larger. If any of the limiting factors change, animal and plant populations change, too.
B)Limiting factors do not prevent populations in ecosystems from growing any larger. If any of the limiting factors change, animal and plant populations do not change, too.
C)Limiting factors can never impact ecosystems.
D)As biodiversity of an ecosystem increases, the ability to withstand environmental stress due to the loss of a single species or group also increases, improving the sustainability of the ecosystem.
Answer:
limiting factors like the availability of food, water, shelter and space can change animal and plant populations. Other limiting factors, like competition for resources, predation and disease can also impact populations. ... Sometimes a population will grow too large for the environment to support.

ENJOY groovie DAYArctic ice retreat is threatening many species in this ecosystem. Their resources are being cut and they are needing to find new ways to survive. Do you think in your lifetime you will see drastic effects to the species in this ecosystem and why? Will that affect other ecosystems?
Answer:
no
Explanation:because they will find new ways to survive in the environment
Answer:
We are already seeing drastic effects to the ecosystem and it's wide assortment of species. Animals such as polar bears, and seals are losing their breeding and hunting grounds. Polar bears in particular are losing their ways to catch seals for food and interbreeding with grizzly bears. Fish and whales from warmer parts of the world are starting to move up north and are becoming invasive. Most importantly, since cold water from the melting ice are mixing with ocean currents, global climates and weather systems are changing course. Ultimately, in about 500 years, there could be a large Global Climatic Shift that may put us into another Ice Age.

A researcher attempts to use a segment of ribosomal RNA as a molecular clock to calculate the date of the last common ancestor of two species. He finds that the two species diverged from a common ancestor 150 million years ago. These particular species have abundant fossil records that strongly suggest that these species diverged 100 million years ago. Which of the following answer choices best describes a reason for the discrepancy in the date of the last common ancestor of these species?
A. Ribosomal RNA is not a reliable molecular clock and should not be used for dating.
B. The neutral mutation rate used in calculating the last common ancestor date may not have been accurate.
C. It is highly likely that the two organisms did not share a common ancestor, so the results are invalid.
D. A large portion of the ribosomal RNA is not vital to survival, so it is not likely to be well preserved.
Answer:
B
Explanation:
It is B because the mutation rate should not have been accurate if it showes that they diverged 150 million years ago. But the abundant fossil records show that it diverged 100 million years ago.
Hope this helps:)

What is molecular docking?In structural molecular biology and computer-assisted drug design, molecular docking is an important technique. The purpose of ligand-protein docking is to anticipate a ligand's most common binding mode with a protein having a known three-dimensional structure.What is dating? Carbon dating is used to determine the age of ancient material such as an archaeological or paleontological specimen .A molecular clock estimates how long it has been since similar species separated from a common ancestor based on DNA sequences (or the amino acid sequence of proteins encoded by DNA).
Hence, the correct option is A.

What are Fossil fuels?A fossil fuel is a hydrocarbon-containing material which is formed naturally in the Earth's crust from the remains of dead organisms such as plants and animals which are extracted and burned as a fuel. The main fossil fuels which are present in the earth's crust include coal, oil, and natural gas.
The evolution of species is easily confirmed by the presence of fossils of the most diverse species of the living beings in the world. This is because, fossils are the records of species which do not currently exist, however there are existed millions of years ago and are similar to the current species, being their ancestors.

Answer:
The products are stored in the form of starch because glucose is soluble
Explanation:
Answer:Although the cuticle provides important protection from excessive water loss, leaves cannot be impervious because they must also allow carbon dioxide in (to be used in photosynthesis), and oxygen out. These gases move into and out of the leaf through openings on the underside called stomata.

State reason(s) why ash should or should not be used in making compost
Answer:
Fireplace ashes for compost can be used to help maintain the neutral condition of the compost. It can also add nutrients to the soil. Decomposing materials in the compost pile can become somewhat acidic and wood ash can help offset this, as it's more alkaline in nature. But Adding too much ash to the pile can be detrimental to the makeup of the compost because of its alkalinity. Ashes tend to raise the soil pH, so you shouldn't use it directly on plants, especially acid-loving ones like rhododendrons, azaleas, and blueberries. Also, in high amounts, wood ash can inhibit plant growth by restricting nutrients, like iron.

Answer:

In cycles of matter when rock has been exposed for mining, the answer is water. Thus, option A is correct.
Can readily transport nutrients from rock to aquatic ecosystems. Runoff that carries excess nutrients can cause algae blooms.The effects of soil erosion. Thus, option B is correct.
What is soil erosion?The removal of the top of the soil by water, wind and human activities has been called soil erosion. The reason due to which soil erosion takes [place is that trees should be planted in several rows to check the speed of the wind. This reduces soil erosion because of wind. Because the rivers cause soil pollution, dams are built in the upper course of the rivers to check soil erosion.
Soil erosion has happens when the dirt has been exposed to the high winds, heavy rains, and rushing water. In few circumstances, human activities, like farming and land clearance, expose soil to erosion. Soil erosion has been considered as the removal and transfer of the top layer of soil from its original location to another due to high winds and fast-running precipitation.
Therefore, Both rock and bodies of water are considered a type of reservoirs. Thus, option C is correct.
In cycles of matter when rock has been exposed for mining, the answer is water. Thus, option A is correct.
