Answer:
I think that wolves are a keystone species because they regulate prey. If they were gone, prey would overpopulate and decrease the population of smaller organisms such as plants. Without plants and other food sources for the prey, the prey would also decrease eventually.
Explanation:
Choose the correct problem for the fraction 25/20. 25 x 20 20 ÷ 25 25 ÷ 20 20 ÷ 20
Answer:
25 divided by 20
Explanation:
for example: 1/4 = 1 divided by 4 which is equivalent to 0.25 or 1/2 = 1 divided by 2 which equals 0.5/0.50
these to give you the amount so 1/4 is equivalent to 25% and 1/2 is equivalent to 0.50% of the whole so now if we do 25 divided by 20 it would be equal to 1.25.

A bowling ball sinking and a ping pong ball floating in water are examples of which kind of property?
a. mass
b. density
c. length
d. weight
a. Make a list of as many traits as you can think of that could be used to classify a new species.
b. Which of the traits in the list above would be most useful for classification at high levels (e.g. classifying things into different kingdoms or phyla) , which would be more helpful at lower levels (e.g. family or genus)
Answer:
a. My list is the following:
1. presence of photosynthetic pigments
2. presence of cell wall
3. body symmetry pattern
4. presence of cell nucleus
5. presence of specialized organelles
6. presence of hair
7. presence of mammal glands
8. niche (e.g., terrestrial or marine habitats)
9. diet (food habits)
10. position of a particular muscle
Explanation:
b. In the list above, traits such as the presence of a cell nucleus or specialized organelles can be used to classify organisms at the kingdom level (since these phenotypic features are observed in eukaryotic organisms but not in prokaryotes). In a similar mode, animals may exhibit two different body symmetry patterns: radial (around the central axis) and bilateral (two sides: left and right), thereby symmetry body can be used to classify organisms within the animal kingdom. Other features used to classify species at high levels include the presence of photosynthetic pigments in green plants (chlorophyll) and bacteria (xanthophyll), presence of cell walls in plants (composed of cellulose,) and fungi (composed of chitin), presence of hair and mammal glands (mammals), etc. On the other hand, ecological differences (e.g., food habits, niche) and minor anatomical differences (e.g., the position of a particular muscle) are helpful to classify species at the family/genus level.
MASTERY CONNECT MITOSIS
Answer:
According to the cell cycle data provided in the table, these data indicate that cells spend most of their time preparing for the cell cycle (third option).
Explanation:
The cell cycle is divided into two major phases, interphase —without cell division— and cell division or mitosis. Interphase in turn is divided into three phases prior to the division process:
G1 phaseS phaseG2 phaseAssuming that the complete cell cycle lasts 24 hours, the cell will remain in interphase for 23 hours - preparing for the next division - investing only 1 hour in cell division or mitosis.
The data provided by the table indicate that, at a given time, there will be a greater number of cells in the interphase stages, indicating that cells spend most of their time preparing for the cell cycle.

The hormones secretin and cholecystokinin target the pancreases. ---, and, ----to release juice and bile into the small intestine for digestion
Answer and Explanation:
The endocrine system organizes the secretion of the hormones and the response of numerous glands in the body. The acid environment of the stomach is the essential factor under hormonal control. Gastrin hormone is secreted by G cells in the stomach during the gastric phase. Gastrin encourages the secretion of hydrochloric acid or stomach acid, which helps in protein digestion. When the stomach gets empty, the stomach's acidic environment needed not to be maintained, then a hormone named somatostatin stops the secretion of hydrochloric acid. During the intestinal phase, digestive secretion from the pancreas, gall bladder, and liver helps digest chyme in the duodenum. A hormone called secretin stimulates the pancreas to produce alkaline bicarbonate solution to deactivate the acidic chyme. In tandem, secretin acts with another hormone named cholecystokinin (CCK). CCK encourages the pancreas to release pancreatic juice and encourages the gallbladder to secrete bile into the duodenum.

Plants move water from the roots of the plant to the leaves through transpiration. As water evaporates from the leaf, cohesion pulls water up from the roots. Suggest a relationship between transpiration and stomata density.
Answer:
Stomata are the organs present on the stem and leaves of the plant and help in the gaseous exchange and evaporating water present in the aerial parts of the plant. Mainly leaves stomata plays role in gaseous exchange and transpiration which is the evaporation of the aerial water of plants by opening and closing the stomata. Stomata are small pores mostly and normally present under the leaves and regulated by the guard cells, dum bell shaped cells to close or close it.
Other than closing and opening the stomata, stomata density also can affect the rate of gas exchange as well as transpiration. Stomata density is the presence of the numbers of the stomata per unit area. In heat or sunny area the stomata density is higher than the shady or dark area to increase the transpiration in order to cool down the leaves of the plant which prevent the chloroplast proteins to denature.
The higher stomatal density should increase the total number of stomata per plant.

Answer:
There are many reasons why manned space probes to Saturn are simply unachievable. Getting to space is incredibly hard. The force of gravity is very hard to escape. If you wanted to, you would have to invest trillions upon trillions of dollars to create a space shuttle that may or may not explode. Second, we simply don’t have the technology to make it that far with a manned probe. Saturn is more than a billion miles away. It would take more than several years to go that far. To keep astronauts alive, entertained, and sustained is also a big challenge. In conclusion these are some reasons why a manned space probe to Saturn is unachieveable.

Laura says that wave A has more energy since it is louder, but Jessica disagrees.
Jessica says that wave A is louder, but has the same amount of energy as wave B since
the wavelength is the same. Who is right and why?
O Neither is right because energy depends on the medium that the waves are traveling through.
Jessica is right. Wave A is louder and wave B is softer.
Laura is right because wave A has a higher amplitude and therefore more energy.
Jessica is right because wave A and B both have the same wavelengths.
Answer:
wave A is louder then wave B

When lava cools and hardens quickly on the Earth's surface, the rock grains are
Answer:
Magma that cools quickly forms one kind of igneous rock, and magma that cools slowly forms another kind. When magma rises from deep within the earth and explodes out of a volcano, it is called lava, and it cools quickly on the surface. Rock formed in this way is called extrusive igneous rock.

Fill in the blank text field 2
Answer:
THE FIRST ONE number 4 is cohesion and the second one number 5 is heat capacity the answer to the one you asked is heat capacity
Explanation:
The temperature of the water is about 5°C, while the temperature of the air is about 21°C. The first number 4 is the cohesion and the second one number 5 is heat capacity.
What is specific heat capacity?The specific capacity is defined as the quantity of heat required to increase the temperature of 1 kilograms Mass by 1 degree Celsius.
Mathematical
Q=mc(dt)
Where
Q = Required amount of heat
M = mass in kg
dt = change in temperature
The law of energy states that energy cannot be created nor be destroyed it only transfer from one form of energy to another form of energy.
In above example as we know that electrical energy has created by potential energy which stored in the form of water in dam after that electrical energy is produced so potential energy converted into electrical energy as a polly switch on the light she change the electrical energy into thermal energy because as we burn light it also develops some heat.
Therefore, The temperature of the water is about 5°C, while the temperature of the air is about 21°C. The first number 4 is the cohesion and the second one number 5 is heat capacity.

What would be your best prediction on the effect of not having ATP available to supply energy to this process
Answer:
The best prediction is the lack of energy in the body, the feeling of tiredness or the lack of administration of healthy foods.
Explanation:
When there is no energy or energetic reserves the fat reserves are depleted, therefore the person is thin, or underweight.
Glycogen stores are also depleted, therefore muscle fatigue is the predominant one.
How might Kangaroo population suddenly increase? How might this affect the ecosystem?
Answer:
The kangaroo population could suddenly increase if the predator of the kangaroo found something else to hunt, or started to go extinct. If this were to happen, then the prey of the kangaroo would most likely go extinct due to the sudden rise in population of the kangaroo. If there were more kangaroo, then there would be less of whatever the kangaroo ate, then the prey of whatever the kangaroo ate would suddenly increase, it goes all the way down the chain.
