Answer:
Storing the food helps them to use it in winter and survive because there is very little sunlight available and so they photosynthesis less. ... When they have extra food they store it in their seeds and when the seed grows it gets it's food from the plant until the plant is able to photosynthesis and produce its food.
Answer:
It's important for plants to store food, as food is a source of nutrition, which is necessary for survival. Rather than just eating the food, storing it is a good way to ensure nutrients during droughts or other harsh conditions that make it hard to find food.

Use Darwin's theory of Natural Selection to explain the process by which the four-legged land animal, A, may have evolved, over about 20 million years, from the fish-like creature, C, in the swampy conditions of the time.
Answer:
Due to environmental conditions.
Explanation:
With the passage of time, environmental conditions change which causes the evolution of of four legged land animals from fish like creature. This change occurs due to change in environment. In water, there is no need for legs because fish moves with the help of fins and tail but the organisms that lives on land has legs in order to move from one place to another so we can say that change in the physical structure of organism occurs due to environment.

Maja puts a hockey puck onto ice. After a while the temperature of the hockey puck decreases. What happens to the molecules of the hockey puck when the temperature of the puck decreases?
Answer: The energy of the molecules in the hockey puck decreases.
Explanation:
When the temperature of the hockey puck decreases, then the energy of the molecules in the hockey puck decreases as well.
In this scenario, when the temperature of the hockey puck decreases, then the hockey puck will gain heat molecules and the cold energy of the molecules that are in the hockey puck will reduce.

Which of the following is NOT a
piece of evidence that Darwin
used to support his theory of
evolution?
A. fossil record
B. similarities among different species
C. the amount of shared DNA between species
Fossil record is not a piece of evidence that Darwin used to support his theory of evolution.
What is the theory of evolution?Evolution is the process of change in all forms of life over generations, and evolutionary biology is the study of how evolution occurs. Biological populations evolve through genetic changes that correspond to changes in the organisms' observable traits.
Darwin proposed that species can change over time, that new species come from pre-existing species, and that all species share a common ancestor. In this model, each species has its own unique set of heritable (genetic) differences from the common ancestor.
The current evolutionary theories can be categorized as Darwinism and Lamarckism. Charles Darwin theorized Darwinism. He explained his theory of natural selection in his book, On the Origin of Species.

↬Define a Cell in Biology.
The cell is the basic structural, functional, and biological unit of all living organisms.
The structural and essential component of life is the cell. Cell biology is the study of cells, including their fundamental makeup and the purposes of each of their organelles.
The first biologist to discover cells was Robert Hooke. Cells make up every living thing. They could consist of several cells (multicellular) or just one cell (unicellular) (multicellular).
The tiniest cells known to science are mycoplasmas. All living things are constructed from cells. They give the body structure and turn the nutrients from the diet into energy.
Complex cells conduct a variety of tasks for an organism's parts. They resemble masonry bricks in that they come in a variety of sizes and forms.

Explanation:
When designing an experiment, you come up with the question: How does the amount you talk to a plant help it grow? Which would be the best hypothesis
Answer:
The correct answer is - "If you increase the amount you talk to plants, then they will grow taller"
Explanation:
A hypothesis is a proposed or assumed explanation for the natural system or problem. It forms on the pre-existed or known data or knowledge. A good hypothesis should have the ability to relate to dependent and independent variables.
In this case, the best hypothesis would be "If you increase the amount you talk to plants, then they will grow taller" as it relates to the dependent and independent variables that are the growth of the plant and talking to the plant respectively.

which of the followimg could be reasons why popultion sizes may reach and maintaim plateaus? choose the three that apply
Will mark as brilliant answer
Answer:
Below :D
Explanation:
So basically, this question is asking what will cause a species' population to reach a point where it stops increasing.
Lets think about what can cause a lack of increase?
A decrease can cause this.
Or a slow in the rate of increase.
Now lets look at our selectable answers and see if any of them would fall under these two things.
First up is fewer deaths.
Well, fewer deaths basically means less of a decrease in population.
This is the opposite of decreasing the populatin count, and would instead raise it.
Next we have a limit in food supply.
This would cause a organism to starve and die.
So this would cause a decrease in population count.
So B is one of the answers
Next up is competition with other species.
When two species compete for a sort of resources, one massivly dies out due to outcompetion, and loses the resources needed to survive.
So this would also cause a large decrease in population count.
This makes C one of the answers
Next is increase in birth rates.
This would cause more organisms to be born of a species, basically increasing the population count.
This is the opposite of a decrease in population.
Next we have competition for space.
This is very similar to answer C, and the outcompeted species dies out due to lack of space.
So E is one of the answers
Now, the next answer seems viable, because major storms can kill off organisms, like hurricanes, earthquakes, and volcanos for instance.
However, as seen in many organisms over history, while these major storms kill of organisms, they can recover.
So although major storms decrease populations, they dont actually limit them.
In the end:
B is correct
C is correct
E is correct
Hope this helps!

Describe TWO environmental consequences, other than those related to the loss of boreal forest habitat, that result from the extraction of bitumen or the transportation of synthetic oil to customers.
Answer: The greenhouse gas emissions from the extraction of bitumen and the use of large quantities of water.
Explanation:
Bitumen is a natural flammable organic matter formed from kerogen in the process of petroleum generation, which is soluble in carbon disulfide. Asphalt and mineral wax are examples of hydrocarbons which are part of bitumen. Conventional oil is extracted by wells while oil sands deposits are extracted using surface mining sectioning techniques, or are flowed to wells by in situ techniques that reduce bitumen viscosity by steam and/or solvents. So, unlike crude oil extracted in oil wells, bitumen requires an open-pit mining operation, in which large tracts are washed with a mixture of water and chemicals to separate the bitumen from a mixture of sand and clay.
Two consequences of this practice are:
The greenhouse gas emissions from the extraction of bitumen are larger than the extraction of conventional oil. The emissions produced contribute to enhance the greenhouse effect and cause global warming. The greenhouse effect occurs when certain gases retain part of the energy emitted by the earth's soil when heated by the sun's radiation. This phenomenon occurs naturally, and thanks to it, the average temperature of the Earth is about 14º C (57.2 °F). The problem occurs when these greenhouse gases increase in the atmosphere and the amount of energy that is not released into space also increases and, with it, the Earth's temperature. The extraction of bitumen from oil sands requires the use of large quantities of water, and even though water used here can be recycled, only a small amounts is returned to the natural cycle. Also, spills from the transportation of the oil could damage soils and waterways, increasing water pollution. This toxic water could get into surface.Which organ releases the hormone insulin in order to regulate the level of blood sugar in the body?

Answer:
The first alligator ancestors evolved about 245 million years ago.
Explanation:
The first alligator ancestors evolved about 245 million years ago due to change in the environmental condition. crocodilians appeared about 80 million years ago during the Cretaceous period. Modern alligators has experience less changes which is closely related to their ancient ancestors and look much like to their relatives that exists about 80 million years ago. The main reason for the change in the body structure of alligator is due to change in environmental condition.
The evolution of alligators can be analyzed by sequencing samples of different species and then producing a bioinformatic analysis.
What is evolution?Evolution means descendence with some class of modification in offspring (phenotypic, genetic, etc).

Answer:
Identical
Explanation:
Binary fission is a form of asexual reproduction. This is when only one parent is involved in creating offspring. Since there is only one parent, two sets of DNA cannot be combined into a new offspring; so, it must be identical.
