Answer:
An allele is a variant of a gene. Everyone has at least 2 alleles for every gene. Because of this, humans are known as diploid organisms.
Explanation:
Genes are the complex proteins that give us hereditary traits such as hair and eye color. But genes mutate, with at least 2 copies per single gene. These copies are known as alleles.
Athletes train at high altitude, thereby increasing the number of red blood cells, to improve their
performance. How might an increase in the number of red blood cells improve an athletes
performance?
Answer:
Preparing at moderate height may improve ocean level execution in perseverance competitors. This was noted after the 1968 Olympics in Mexico City (7600 feet) when a few competitors found an improvement in their presentation after re-visitation of ocean level. Be that as it may, different competitors didn't see any distinction in execution. Studies have indicated improved high-impact power in sprinters who prepared at 6,000 feet for 10 days at that point performed at low elevation. Lower oxygen levels at elevation invigorate EPO prompting expanded red platelets or hematocrit. This viably permits more oxygen to be conveyed to the tissues. Basically, this is blood doping the regular way.
Late examinations do propose profits by 'preparing low' and 'dozing high'. This incorporates hypoxic tents that numerous competitors are presently utilizing. These tents have a generator that extricates oxygen from the air, establishing a moderate height climate. Competitors at that point rest/relax in them for a few hours per day. This invigorates erythropoietin, subsequently expanding the hematocrit (red platelet tally). Without a doubt the 'live high, train low' idea may permit the best blend. One examination separated 39 contenders into three preparing gatherings; living and preparing adrift level, living at height and preparing adrift level, living at elevation and preparing at height. The two gatherings who inhabited height had expanded red platelets and VO2max, however just the gathering who lived high and prepared adrift level had improved race times. One clarification for this is that the live high, train low gathering can prepare more diligently and better use their blood's oxygen conveying limit. As a result of expanded red cell creation, all competitors preparing as well as resting at elevation should ensure they have proper iron stores and nourishment. This is particularly valid for ladies, as they will in general have lower iron stores because of occasional loss of blood through monthly cycle.

how do populations and communities affect one another?
Answer:
How can a change in one population affect the entire community in an ecosystem? If one population dies out, all the populations that depend on that species for food may also die out. A change in one population affects the entire community because all the populations of a community depend on each other.

How does the Earth's atmosphere interact with the sun's rays? A. The atmosphere absorbs the sun's energy and holds it as heat to warm the Earth. B. The sun is outside of the atmosphere and doesn't interact with it at all. C. The atmosphere deflects the sun's poisonous elements. D. None of the above
Answer:
The atmosphere absorbs the sun's energy and holds it as heat to warm the Earth
Explanation:
This is because the atmosphere also interacts sun radiations that comes in contact with through a process called molecular scattering. Light rays are very minute and there are alot of small molecules that float in the atmosphere and when light comes from the sun, the smaller molecules scatter the Ray's and it warm the Earth. Huge numbers of small molecules float in the atmosphere. There is a layer called ozone which absorb sun radiations.
You overhear Kali describing her trip to the ocean to a friend. She explains that she waded out onto the continental rise, but was careful not to go too far, because she didn’t want to reach the steep decline of the continental slope. What part of her story needs to be corrected?
A. She needed to be careful of the continental shelf, not the slope.
B. She was on the continental shelf, not the continental rise.
C. She was on the continental slope and needed to be careful of the rise.
D. Continental slopes are not steep declines, they are gradual.
Answer:
B. She was on the continental shelf, not the continental rise.
Explanation:
The continent first contacts the ocean at the continental shelf. After a while, the continental shelf ends in a steep decline known as the continental slope. The continental slope eventually levels out into a gradually sloping continental rise which eventually becomes the ocean floor.
The part of her story that needs to be corrected is that she was on the continental shelf, not the continental rise. The correct option is B.
What is continental shelf?A continental shelf is a portion of a continent that is submerged beneath a shallow body of water known as a shelf sea.
During glacial periods, sea level drops exposed many of these shelves. The shelf surrounding an island is known as an insular shelf.
The continental shelf is where the continent first makes contact with the ocean. The continental shelf eventually ends in a steep decline recognized as the continental slope.
The continental slope eventually flattens out and becomes a gradually sloping continental rise, which eventually becomes the ocean floor.
Her story needs to be corrected because she was on the continental shelf, not the continental rise.
Thus, the correct option is B.

TRUE OR FALSE: Phospholipids that are a part of the nuclear envelope (membrane around the nucleus) can easily move from one part of the cell to another, and may ultimately become part of the cell membrane, the ER, a vesicle membrane, etc. In fact, any phospholipid may be called a "cellular tourist" because it is able to move about to virtually any part of a cell and can even become a part of a cell in a different region of the body! (EXPLAIN WHY)
Answer:
False, because phospholipids are a type of lipids and the nuclear envelope contains nucleic acids.
Explanation:
Hope this helps.
It is true that phospholipids that are a part of the nuclear envelope (membrane around the nucleus) can easily move from one part of the cell to another, and may ultimately become part of the cell membrane, the ER, a vesicle membrane, etc.
What is nuclear envelope made of?The nuclear envelope is made up of two concentric lipid bilayer membranes separated by a 20-40 nm intermembranous space.
In many places, the outer membrane is joined to the rough endoplasmic reticulum. The outer membrane of the nuclear envelope, like the rough ER, is dotted with ribosomes.
The nuclear envelope is made up of two membranes: an outer and an inner phospholipid bilayer. The lumen of the rough endoplasmic reticulum is connected to the thin space between the two layers (RER).
Nuclear pores, which are small channels that run across the nuclear envelope, allow substances to enter and exit the nucleus.
Each pore is lined by a group of proteins known as the nuclear pore complex, which regulates which molecules can enter and exit.
Thus, the given statement is true.

equation of gaseous exchange in plants
Answer:
See the answer below
Explanation:
Gaseous exchange in plants involves the entering of oxygen and the exit of carbon dioxide in its place. It is an important process that helps sustains the life of plants, just like every other living organism. The oxygen that enters is utilized in the process of respiration during which carbohydrates are broken down to unlock their energy for metabolic activities.
Oxygen usually diffuses-in through the stomata while the carbon dioxide diffuses in the opposite direction. The summary of the gaseous exchange is summarized in the equation below:
Glucose (food) + Oxygen ---------> Carbon dioxide + water + energy
Or better still;

A classmate explains that igneous rocks can be changed to metamorphic rock by first being melted into magma and then cooling. What correction needs to be made to this statement?
Answer:
Cooled magma becomes igneous rock
Explanation:
Took the quiz
Rocks can be created in a variety of ways, such as when sand is crushed or when volcanoes erupt.
What are rocks?There are three different types of rocks: metamorphic, sedimentary, and igneous. These rocks can all alter. In actuality, any rock may transform into any other kind of rock.
Condensation and cooling: The Earth's interior can experience temperatures hot enough to produce magma. Igneous rock is created as crystals develop in the cooling magma.
If the lava cools gradually, as it does if it stays inside the Earth for an extended period, the crystals enlarge. The crystals will be very tiny if the magma cools quickly. Crystallization is the process by which crystals emerge from magma.
Therefore, Rocks can be created in a variety of ways, such as when sand is crushed or when volcanoes erupt.
