What traits could help a predator be more "fit" to survive in each environment? be specific.
Answer:
If a predator was able to camouflage into the environment, if he made little noise, had good hearing, and could move fast, he would probably be more fit. Appearance could affect an individual's survival; not just color, but maybe sharp teeth, rough skin, a beak, or claws to fight of predators. High strength and speed are great as well, but in some species, being slower may assist their hunting, depending on their environment.
Explanation:
Answer:
If a predator can camouflage its surroundings, make less noise, have good hearing, and can move quickly, it is likely to be more suitable. Appearance can affect a person's survival. Not just the color, but also the sharp teeth, rough skin, and beak and claws to fight predators. High power and acceleration are also great, but for some species, slower can be useful counting on the environment when hunting. I have.

What is unique about water on Earth?
Group of answer choices
All of the above.
Water has tremendous kinetic energy because of the strength of Earth's gravity.
Water can be found naturally in its solid, liquid and gas forms.
Water can be found in the outermost layers of the atmosphere, all the way down to the planet's core.
Timed test hurry!!
Answer:Water is unusual in that it can occur naturally in three distinct forms – gas, liquid and solid – at the same time. ... And if you look up, you see evidence for water vapor, water's gaseous form, in the clouds floating in the sky. Most substances contract as they freeze, but water expands.
Explanation:
Estella spilled tomato sauce on her shirt. When she washed her shirt, she noticed that the detergent she used contained enzymes. Enzymes are added to detergents to break down proteins from food and other substances that may stain clothing. Which would MOST likely inhibit the ability of the enzymes to remove the stain on her shirt?
Answer:
the temperature of the water
Explanation:
Enzymes have a defined temperature range at which they work the best. At temperatures outside of this range, the enzymes will not work well.
At high temperatures, enzymes can become denatured, meaning their structure is destroyed and they will have no activity.
The hormone __________ increases the blood level of calcium.
Answer:
PTH
Explanation:
PTH raises calcium levels by releasing calcium from your bones and increasing the amount of calcium absorbed from your small intestine. When blood-calcium levels are too high, the parathyroid glands produce less PTH . But sometimes one or more of these glands produce too much hormone.

What happens when proteins in egg white are denatured?.
|| ▼ Answer ▼ ||
When the egg white is denatured like what is done in frying or boiling an egg, the protein present in the egg white will be coagulated.
|| ✪ Explanation ✪ ||
The texture of the egg will change due to denaturation. With the application of heat, protein is coagulated by losing its bonds for its shape. When the egg is boiled, the protein present will group together making the egg texture hard. Denaturation of proteins contributes to the change of their structure and thereby losing their function.
Hope this Helps!
If you have any questions please ask.
Answer:
Denaturation of proteins in egg disrupts the tertiary structure of proteins.
Explanation:
The bond between the charged groups and the non-polar groups is altered. This takes place at high temperatures and it is an irreversible denaturation. it results to whitening of the albumen

the relationship between glucose molecules, the respiratory system,
and cellular respiration.
Answer:
The process of using glucose to make energy is called cellular respiration. The reactants, or what we start with, in cellular respiration are glucose and oxygen. We get oxygen from breathing in air. Our bodies do cellular respiration to make energy, which is stored as ATP, and carbon dioxide.

what is the difference between a stem cell and a differentiated cell,such as a red blood cells?
Answer: Stem cells can become a variety of types of cells, while differentiated cells like red blood cells are fully specialized cell types.
A stem cell produces a mesoderm cell, which can then further differentiate to form a muscle stem cell.
Stem cells are the unspecialized cells which are capable of self-renewing and differentiating into mature cells while differentiated cells are specialized to perform a specified function in the body.
Stem cells have the potential to become any type of cell once they are further along in development. Differentiated cells, on the other hand, already have a set purpose and can only become one type of cell when they develop and mature.
Explanation: Hope this helps! Please tell me if anything is wrong. <3
The difference between a stem cell and other cells like red blood cells is stem cells are unspecialized cells that are capable of self-renewing and differentiating into mature cells.
What are stem cells?Using additional differentiation, a mesoderm cell produced by a stem cell can develop into a muscle stem cell.
While differentiated cells are specialized to carry out a certain function in the body, stem cells are the unspecialized cells that are capable of self-renewal and differentiation into mature cells.
Once they reach a later stage of development, stem cells have the capacity to evolve into any form of cell. Differentiated cells, on the other hand, have a predetermined function and can only develop into one type of cell.
Therefore, differentiated cells, such as red blood cells, are fully specialized cell types, whereas stem cells can develop into a range of cell types.

How did Lamarck influence Darwin? How was Darwin's view of evolution different than Lamarck's?
Unlike Darwin, Lamarck held that evolution was a constant process of striving toward greater complexity and perfection. Even though this belief eventually gave way to Darwin's theory of natural selection acting on random variation, Lamarck is credited with helping put evolution on the map and with acknowledging that the environment plays a role in shaping the species that live in it.
Lamarck believed that living things evolved in a continuously upward direction, from dead matter, through simple to more complex forms, toward human "perfection." Species didn't die out in extinctions, Lamarck claimed. Instead, they changed into other species.
