Answer:
Convection takes place in the atmosphere, in the oceans, and in Earth's molten subcrustal asthenosphere. Convective currents of air in the atmosphere are referred to as updrafts and downdrafts. In addition to heat transfer, convention can be driven by other properties (e.g., salinity, density, etc)
Explanation:
Convection takes place in the atmosphere, in the oceans, and in Earth's molten subcrustal asthenosphere.
What do you mean by convection?Convection is the process of losing heat through the movement of air or water molecules across the skin. The use of a fan to cool off the body is one example of convection.
Convection currents are present in the air– A good example of convection current is the warm air that rises towards the ceiling in your house. The process happens as the warm air is said to be less dense than that of the colder air.
The best description of a convection current is that e. it is the process in which warm material expands and rises while cool material contracts and falls.. Convection current in the atmosphere causes warm air to rise up from the surface.

Answer:
The answers are DNA contains genetic material and X-ray diffraction.
Explanation:
For question 3 the answer is DNA contains genetic material!!
Hershey and Chase used radioactive isotopes to label a bacteriophage. ... After allowing the bacteriophage to infect the bacteria, the presence of radioactive phosphorus in the bacteria confirmed that DNA was the genetic material found in genes!!
For question number 4 the answer is X-ray diffraction!!
X-ray crystallography
Taken in 1952, this image is the first X-ray picture of DNA, which led to the discovery of its molecular structure by Watson and Crick. Created by Rosalind Franklin using a technique called X-ray crystallography, it revealed the helical shape of the DNA molecule.

A flu virus can remain infectious on surfaces such as desk and doorknobs for long periods of time how does the ability of the flu virus to remain infectious on surfaces lead to high rates of the flu illness
Answer:
because the germs spread and when other people touch it and are carriers and they will probably get sick too
Explanation:
Cells that do not have clearly defined nucleus and no organized chloroplasts, mitochondria, or other organelles are
O Eukaryotic
ukaryotining
O Prokaryotic
Plants
O Fungi
Animals
Answer:
One of the main differences between prokaryotic and eukaryotic cells is the nucleus. Prokaryotic cells lack an organized nucleus while eukaryotic cells contain membrane-bound nuclei (and organelles ) that house the cell's DNA and direct the synthesis of ribosomes and proteins.
The function of a virus?
the function of a bacteria?
Answer:
the function of a virus is to deliver its genome into the host cell to allow its expression by the host cell. It will, at least attempt to, take over the body and infect the body with the disease virus on it.
the function of a bacteria can be good or bad. for good purposes for example, would be the digestive bacteria that breaks down the food and uses the energy to give the body energy. the bad version of bacteria is to spread from surface to surface, like the flu for example.
Explanation:
This tree contains example of several food Chains .bird live in the tree and eat insects they find within the branches .insects eat part of the tree .the transfer of energy moves from the tree to insects and then to birds.
Where does the tree get its energy from? Where does the energy for these food chains begin?
A. As wind energy
B. As solar energy
C.as kinetic energy
D. As synthetic energy
how does energy flow in this terrarium in terms of cellular respiration? I WILL MARK BRAINLIEST
Answer:
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. Without oxygen, much less ATP would be produced.

What factors might affect the availability of fish to eat for the egret and stork
populations?
Answer:
Factors such as pollution, the depth at which both birds go down to catch the fish (if you look at experiments populations of fish tend to deplete quicker when in a shallow depth than a deeper depth), another factor would be the use of mammals fishing for food- this factor can range from a bear all the way down to humans taking huge quantities of fish in from the sea.
These are only a few factors I could genuinely think of.

Answer:
This is actually C,
"Dam Lake the Rainy River, Shoal Lake, Kakagi Lake and smaller rivers that feed Lake of the Woods to restrict algae populations."

A dam would stop spread, and therefore stop algal growth. I saw the skip from B to D, and assumed that C was another answer. If not, apologies!
HELP ASAPPP Why can insertions and deletions affect more than just the codon(s) that they directly change? Hint: Why are they called frame-shift mutations?
Answer:
Insertion or deletion results in a frame-shift that changes the reading of subsequent codons and, therefore, alters the entire amino acid sequence that follows the mutation, insertions, and deletions are usually more harmful than a substitution in which only a single amino acid is altered.

Answer:
C) Radio waves are used to transmit television and radio programs.
Explanation:
Radio wave is a form of electromagnetic radiation which is used in communication technologies, such as radio, television, and mobile phones. Communication technologies or devices receive radio waves and then they are converted into mechanical vibrations in the speaker that creates sound waves.
Hence, the correct answer is "C) Radio waves are used to transmit television and radio programs."

What part of the rotifer is responsible for crushing food?
I said foot but I might be wrong. Help, anyone?
Answer:
Rotifers are specialists at living in habitats where water dries up regularly.
The Monogononta, which have males, produce fertilised 'resting eggs' which can resist desiccation (drought) for long periods.[11]
The Bdelloids, who have no males, contract into an inert form and lose almost all body water, a process known as cryptobiosis. Bdelloids can also survive the dry state for long periods: the longest well-documented dormancy is nine years. After they have dried, they may be revived by adding water. In this, and several other ways, they are a unique group of animals.[12]
Explanation:
The front has a ring of cilia circling the mouth. This gave the rotifers their old name of "wheel animalules". There is a protective lorica round its body, and a foot. Inside the lorica are the usual organs in miniturised form: a brain, an eye-spot, jaws, stomach, kidneys, urinary bladder.
Rotifers have a number of unusual features. Biologists suppose that these peculiarities are adaptations to their small size and the transient (fast changing) nature of its habitats.
Answer:
Trophi (got it right on my quiz)
Explanation:
The trophi located behind the rotifer's mouth are responsible for crushing food.
The key to protecting the oceans is
preventing or reducing pollution from the land and from streams.
O reducing population growth along the coastline,
O None of these are correct.
building desalination plants to maintain freshwater supplies for coastal populations
Answer:preventing or reducing pollution from the land and from streams
Explanation: This is true because these said streams and other bodies of water can flow into the ocean
The key to protecting the oceans is preventing or reducing pollution from the land and from streams is reducing population growth along the coastline. The correct option is A.
What is pollution?Pollution is the release of potentially harmful substances into the environment. These potentially damaging compounds are referred to as pollutants.
Despite the fact that metropolitan areas are often more polluted than the countryside, pollution can nonetheless migrate to isolated locations where no one lives.
For instance, it has been demonstrated that the Antarctic ice sheet contains chemicals and pesticides. The Northern Pacific Ocean's Great Pacific Garbage Patch is a vast collection of little plastic waste.
Therefore, the correct option is A, reducing population growth along the coastline.
