what do you think would happen if you put a small seedling in complete darkness for a month but kept all other environmental conditions the same?
If we put a small seedling in complete darkness for a month but kept all other environmental conditions the same the seed will not develop into a seedling because they need solar light during this process.
What is germination?Seedling development or germination refers to the physiological process by which a seed develops into a seedling, which already contains three fundamental plant organs (i.e., roots, shoots and leave). This process (seedling development) requires light.
In conclusion, if we put a small seedling in complete darkness for a month but kept all other environmental conditions the same the seed will not develop into a seedling because they need solar light during this process.

What are the characteristics of muscle?
Answer:
-It thrives during times of intense, or sustained, physical activity.
-The need for increased carbohydrates to sustain that extra level of exertion.
-It's the primary tissue in the human body with herculean strength which makes it very efficient at doing heavy work.
-It becomes rigid when it becomes depleted of oxygen, which is what causes cramping around muscles during intense bouts of exercise where you are doing something like sprinting or weight lifting too fast for your body to keep up through oxygenation alone. This is called anaerobic glycolysis - where there isn't enough oxygen present to use all the sugars being metabolized by your muscles even NEEDED by their quick contractions.

Some traits in animals are more to attract their mates, to reproduce, these traits increase the chances of increasing the population of that animal.
What are courtship display?Courtship display is the group of behaviors that animals show to attract their mates.
Generally, the males have bright colors and attractive features to attract females.
The behaviors are vocalization, beauty, bright colors, different types of features.

There are many points during the cell cycle when the process of division may stop because of a problem. Sometimes the process doesn’t stop. Summarize the function of apoptosis in the cell cycle.(1 point)
to destroy damaged or old cells
to destroy damaged or old cells
to facilitate cell reproduction before the cell cycle restarts
to facilitate cell reproduction before the cell cycle restarts
to allow the cell to rest before the cell cycle restarts
to allow the cell to rest before the cell cycle restarts
to repair damaged or old cells
to repair damaged or old cells
The function of apoptosis in the cell cycle is to destroy damaged and/or old cells. In this case, we can consider that the first answer option is the correct option.
Apoptosis is a programmed death, where the cells promote massive destruction when they "realize" that they can create problems for the organism.
This process takes place as follows:
A cell retraction begins so that the cell cannot adhere to other cells or substances.The chromatin becomes condensed.The cell membrane elongates, forming structures known as "blebs."The cell nucleus disintegrates completely.The blebs break off, forming an apoptotic body.The apoptotic body is unprotected from the action of phagocytes that can destroy the molecule.More information:

Three pieces of evidence of universe expansion support the Big Bang Theory. The first piece of evidence, which Edwin Hubble discovered, is that_____
The second piece of evidence is the change in universal temperature. The temperature_____
The third piece of evidence is that Cosmic Microwave Background radiation is found______
:: uniformly across the universe
:: has increased dramatically
:: galaxies are moving toward each other
:: galaxies are moving away from each other
:: has decreased dramatically
1)a distant luminous object travels rapidly away from an observer.
2)Dark matter provides the gravity that allows the stars to rotate at the same speed.
3)1 galaxy is moving away from each other 2 has decreased dramatically 3 uniformly across the universe
4)1 matter 2 formations of galaxies 3 remained uniform
5)Nuclear fission takes place in the core of stars.
6)The gravity of dark matter distorts light from distant sources.
7)They both occur in the nucleus of an atom. -They both release large amounts of energy.
8)It is the proportion predicted to be present in the early universe.
8)Through dark energy, the universe is expanding at a faster and faster rate. -Because of dark matter, gravitational interactions cause galaxies to develop.
9)It verifies that the early universe was once extremely hot.
Hello, Connexus friends hopes this helps this is all the review questions + they correct cuz I got 10 out of 10 let me know if you need help!
The first piece of evidence Hubble has discovered is that galaxies are moving away from each other. The second piece of evidence is that the universal temperature has increased dramatically. The third piece of evidence is that cosmic microwave background radiation is found uniformly throughout the universe.
We can arrive at this answer because:
The Big Bang theory claims that the universe and all of its elements arose from a strong explosion.Although it is a debated and questioned theory, Edwin Hubble found evidence that proves its veracity and is accepted by many scientists.Within this evidence, Hubble claims that the universal temperature continues to increase drastically, which causes the galaxies to move away.The Big Bang was generated from a large amount of pressure and temperature, which caused the universe to expand, so Hubble's evidence may be true.Furthermore, Hubble claims that cosmic microwave background radiation is found uniformly throughout the universe and that this is a trace of the Big Bang.
