Here are some fact about sharks that i found cool
#1
Possibly one of the most evolved sharks today are hammerhead sharks. They have an advanced sensory system and a body shape that has adapted to hunt specific prey
#2
Sharks may be one of the most important species on Earth. They have been maintaining our oceans for over 400 millions years.
#3
Sharks have evolved and changed much over millions of years. However many sharks today still share some of the features as sharks from millions of years ago.
#4
Sharks have been in our oceans for over 400 million years. Some of the earliest sharks were discovered dating back to the Devonian age.
#5
Sharks have survived five massive planet extinction events. These extinction events killed most life on earth and the last one around 65 million yeas ago killed the dinosaurs.
#6
There are over 500 species of shark.
#7
It is believed that each whale shark's pattern is unique, like a human's fingerprint.
#8
Sharks do not have bones. Instead, they have cartilage, that's what makes up human noses and ears
#9
According to the Smit.hsonian, there are over 500 known shark species, though many are endangered or declining due to various factors like overfishing.
#10
Your odds of getting attacked and killed by a shark are 1 in 3,748,067. In a lifetime, you are more likely to die from fireworks or lightning. Whereas over 100 million sharks are killed every year by humans.
#11
Whale sharks are the world’s biggest fish.
#12
Sharks mature slowly and reach reproductive age anywhere from 12 to 15 years.
#13
Hammerhead sharks' eyes are on the sides of their heads, so they have nearly a 360-degree sight line. Their panoramic view of the undersea world is inhibited by two blind spots, one in front of the snout and the other directly behind the head.
#14
Sharks predate the dinosaurs by 200 million years.
#15
Great whites can detect one drop of blood in 25 gal (100 L) of water and can sense even tiny amounts of blood in the water up to 3 mi (5 km) away.

the FUNCTION of enzymes. YOU MUST USE
THE WORDS CATALYST, ACTIVATION
ENERGY, RECYCLABLE
Answer:
Enzymes help speed up chemical reactions in the human body. They bind to molecules and alter them in specific ways. They are essential for respiration, digesting food, muscle and nerve function, among thousands of other roles.
What is the function of an enzyme? They allow chemical reactions to occur at normal body temperature fast enough to sustain life. They reduce the activation energy needed to start a chemical reaction.
There are four steps in the process of an enzyme working. (1) An enzyme and a SUBSTRATE are in the same area. The substrate is the biological molecule that the enzyme will work on. (2) The enzyme grabs onto the substrate with a special area called the ACTIVE SITE.

Enzymes create chemical reactions in the body. They actually speed up the rate of a chemical reaction to help support life. The enzymes in your body help to perform very important tasks. These include building muscle, destroying toxins, and breaking down food particles during digestion.

If the amount of CO2 in the atmosphere increases, do we expect to record an increase or decrease in the pH of the ocean? Why?
Answer:
As the atmospheric concentration of carbon dioxide above water increases, the acidity of the water will increase causing the pH to decrease.

A cell is placed in a hypertonic solution. Which will most likely occur as homeostasis is maintained in the cell?
A.
The cell will gain ATP molecules.
B.
The cell will gain water.
C.
The cell will lose water.
D.
The cell will lose sodium ions.
Answer:
B the cell will lose water
Explanation:
Because of the hypertonic solution water will move on the concentration gradient leaving the cell and entering the solution. Thus the cell looses water.
When a cell is placed in a hypertonic solution, it will most likely lose water (Option C) as homeostasis is maintained in the cell.
What is homeostasis?Homeostasis is the ability of an organism or a system to maintain a relatively stable internal environment, despite changes in external conditions. It is a key aspect of biology that helps living organisms survive in their environment. Homeostasis is maintained through a series of physiological processes that regulate different aspects of an organism's biology, such as temperature, fluid balance, and pH
A hypertonic solution is one that has a higher concentration of solutes (e.g. salts) outside the cell compared to inside the cell. This creates an osmotic pressure gradient, which draws water out of the cell and into the solution in an attempt to balance the concentration of solutes on both sides of the cell membrane. As a result, the cell will shrink and lose water.

Answer:
Humus
Explanation:
Humus is dark, organic material that forms in soil when plant and animal matter decays. When plants drop leaves, twigs, and other material to the ground, it piles up. This material is called leaf litter. When animals die, their remains add to the litter. Over time, all this litter decomposes

Explain the 5 ways to reach Hardy-Weinberg equilibrium, does this mean evolution is occurring?
There are five basic Hardy-Weinberg assumptions: no mutation, random mating, no gene flow, infinite population size, and no selection. If the assumptions are not met for a gene, the population may evolve for that gene (the gene's allele frequencies may change).

The farmer realizes he could sell mini-dragons as pets, but doesn't want them to breathe fire, because that would be dangerous. Suggest two parental genotypes for parents that would produce mini, non-fire breathing dragons.
Answer:
ddff and DDFf
Explanation:
From the information given:
Let DD represents the dwarf traits and FF represents the ability for the dragons to breathe fire.
Also, if dd represents the normal traits and ff represents the inability of the dragons to breathe fire.
Then; we can cross a dominant trait for dwarfism which has a heterozygous trait for fire with a recessive trait of normal and nonfire.
The two parental gametes are: ddff and DDFf
Using a Punnet Square:
DF Df
df DdFf Ddff
df DdFf Ddff
From above; we could observe that the proportion of progenitors that will be dwarf and at the same time unable to breathe fire is 50%.

In three to five sentences, construct an argument that shows why lichens are necessary to establish a new ecosystem after an extreme disturbance.
I would really appreciate it if someone o two people would help me out on this one
Answer: Lichens affect every species in the ecosystem, in 2013 Russia had a dramatic lichen die off which caused 61,000, 20% of the entire reindeer population to die from starvation. And with fewer deers, the bears and wolves also suffered from the loss of lichens and if it takes a long time for lichens to grow back in an ecosystem, animal declines may take years if ever to be corrected. Lichens serve as a basis for several food chains, especially in artic communities.
The argument which shows why lichens are necessary to establish a new ecosystem is as follows;
Lichens are known to enable algae to live all over the world in many different climates.
On this note, lichens also provide a means to convert carbon dioxide in the atmosphere through photosynthesis into oxygen, a process required by all to survive.
Additionally, lichens provide us with valuable information about the environment around us.
On this basis, lichens are important for establishing a new ecosystem after an extreme disturbance.

1. Shivering when you are cold is an example of your body trying to maintain
homeostasis.
a. True
b. False
Answer:
true
Explanation:
When the core body temperature drops, the shivering reflex is triggered to maintain homeostasis. Skeletal muscles begin to shake in small movements, creating warmth by expending energy. Shivering can also be a response to a fever, as a person may feel cold.
