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.
Explanation: Hope it helps!!!
Why is it important to keep things from moving through a window screen
Answer:
Brainliest
Explanation:
Skylight damage is particularly problematic because it an allow moisture to seep into the roof structure and lead to mold and structural damage. Even the rips in window screens limit your protection from the elements as bugs start moving into your home through the ripped screens and cracked windows.
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:
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.

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.

Explanation:
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.
Algal blooms are a concern in marine and freshwater environments such as Minnesota's Lake of the Woods. Which of these would
NOT help to eliminate algal blooms in this environment?
-))
A)
Increase programs to treat wastewater in Minnesota,
B)
Regulate and reduce the overuse of fertilizers in agricultural areas of the
state.
Dam Lake the Rainy River, Shoal Lake, Kakagi Lake and smaller rivers that
feed Lake of the Woods to restrict algae populations.
D
Following yard work, leaves, grass and other debris should be bagged and
removed from the property to prevent them from accumulating and
decaying in the waterbody,
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."
Explanation:
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!

Answer:
Chemical change
Explanation:
Answer:
chemical
Explanation:
ATP and ADP both play a role in cellular reactions involving energy. How are these two molecules related
Explanation:
If a cell needs to spend energy to accomplish a task, the ATP molecule splits off one of its three phosphates, becoming ADP (Adenosine di-phosphate) + phosphate. The energy holding that phosphate molecule is now released and available to do work for the cell. ... When it's run down, it's ADP.
ATP is converted into ADP and ADP can be changed back to ATP by the addition of a phosphate group.
How many membranes cover the Golgi apparatus?
Answer:
The Golgi apparatus (GA), also called Golgi body or Golgi complex and found universally in both plant and animal cells, is typically comprised of a series of five to eight cup-shaped, membrane-covered sacs called cisternae that look something like a stack of deflated balloons.
Explanation:
The Golgi apparatus is a series of membranes shaped like pancakes. The single membrane is similar to the cell membrane in that it has two layers. The membrane surrounds an area of fluid where the complex molecules (proteins, sugars, enzymes) are stored and changed.
Answer:
3 to 8 membranes called cisternae
what will happen to us if our body temperature fluctuate
Answer:
If the body temperature is too low, the enzymes in the body become inactive so many metabolic reactions cannot happen effectively, our metabolic rate will be affected, we may suffer from hypothermia.
If the temperature is higher than 37degree celsius, we will have a fever. But this actually allows enzymes to work at their optimum temperature, which speeds up the metabolic reactions in the body and is good for us.

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.
Hopefully this helps :)
