Answer:
true
Explanation:
Answer:
True
Explanation:
1. A volcanic eruption levels the land in the surrounding area,
covering everything with ash and killing almost all living things. This is
classified as a
limiting factor.
2. As the population of elks in a forest increases, the decreasing
availability of their food source, aspen and willow leaves, acts as a
limiting factor.
3. Part of a forest is clear-cut to make room for new buildings and
roads as part of a housing development. This decreases the available
habitat for all species, making it a
limiting factor.
The limiting factors for these scenarios are density dependant or density-independent.
The growth or decrease of a population depends on factors that can or cannot be related to the number of inhabitants that the population has.
Density dependant limiting factors: the growth rate of a population changes due to the increase in a population's density, that is to say, the number of inhabitants, has a direct impact on the growth or decrease of this population.
Density Independent limiting factors: the growth rate of a population changes due to factors that are not related to the population itself. In other words, they are external factors, such as a volcanic eruption, that affect the rate.
In conclusion, a volcanic eruption covering everything in ash and killing almost all living things is a density-independent limiting factor. The increase in the population of elks and the decrease in their food source is a density dependant limiting factor, which makes elks compete for food. Lastly, part of a forest being clear cut to make room for buildings, and decreasing the available habitat for species is a density-independent limiting factor.

Chose ALL the choices that are true about exponential growth: a Rapid (fast) period of growth b Has carrying capacity c "S" curve d "J" curve e Takes place when there are lots of resources ex: food, space f Takes place when there are limited resources ex: food, space
Answer:
a, d, and e
Explanation:
The exponential growth is a period characterized by rapid growth as a result of the availability of unlimited resources for the use of the population. Once the population spends a short period getting acclimatized to their environment, a period of rapid growth follows that is devoid of any limitation and thus, the growth curve forms a 'J' shape. This type of growth has no carrying capacity that limits its growth and may not be possible in real life where resources are limited.

Which process binds together sediment to form new rock?
cementation
compaction
deposition
erosion
Answer:
It will be (cementation).
That's the correct answer.
The process that binds together sediment to form new rock is cementation. The correct option is A.
What is cementation?Cementation is the process of mineral materials precipitating in the pore spaces to harden and weld clastic sediments (those generated from preexisting rock pieces). It is the final phase of sedimentary rock formation.
Through cementation, sediments become sedimentary rock. In the spaces between the sediment particles, this action causes the precipitation of minerals.
Examples of cementing include carbonate hard ground and beach rock. Black rock is a particular kind of rock that develops along the shore and is composed of a wide variety of sediment types and sizes that have been cemented together.
Therefore, the correct option is A. cementation.

What will happen if gametes were diploid cells?
Answer:
If gametes were produced instead by mitosis each gamete would be diploid not haploid. During fertilization of diploid gametes, the zygote would become 4n=92. With each new generation the number of chromosomes would double.
Alice wants to find out whether her pet gecko finds its prey based on vision. She thinks that her gecko will more easily see the colored crickets. She follows these steps:
get 10 similar crickets from the pet store
tag 5 of the crickets by putting a tiny dab of bright coloring on their backs
release all 10 crickets into the terrarium with the gecko at the same time
after several hours, record the number of tagged and non-tagged crickets still alive in the terrarium
After several hours, Alice notes that only 4 non-tagged crickets were still alive in the terrarium. No tagged crickets were observed. She concludes that her gecko uses mostly its vision to capture and eat its prey.
What is another possible explanation for these results?
She relays more on her vision than her other senses so you could assume she has good eye sight or something.

Limiting factors in water bio mes include
amount of salt
amount of dissolved oxygen
amount of sunlight
all of the above
Answer:
all of the above
Explanation:
Water biomes describe all the living things living in an area of water such as a lake or ocean. The surrounding environment plays a huge part in what organisms able to live there.
For example, green plants and algae require sufficient sunlight and oxygen to perform photosynthesis. Green plants and algae are an important food source for many other organisms. The amount of salt is important for various fish, as they will be unable to survive in very high salt concentrations. Therefore, all of the above are limiting factors.

The evolution of a species is dependent on changes in the genome of the species. Identify two mechanisms of genetic change, and explain how each affects genetic variation.
Answer:
Mutation, fertilization, meiosis are different mechanisms by which changes can occur in the genome.
Explanation:
There are several process which is responsible for causing change in the genome of the species which results in the evolution of that species. Some of these processes are:
1. Mutation: In mutation, some nucleotide sequences get change and this change can occur due to frameshift, addition, deletion or any other process. This change in nucleotide can be seen in phenotype and helps in the evolution of the species.
2. Fertilization: During fertilization mixing of the genome of two individual takes place which results in producing a genetically distinct offspring which contains variation. So as the offspring is genetically different it can contain new alleles that can help the individual to survive in the changing environment.
Two mechanisms or vehicles through which genetic change occurs are;
Mutation and Gene flowMutation occurs when there is a mistake in the DNA sequence of an organism. When an egg and a sperm bearing the faulty DNA sequence mate, a mutated organism is formed.
A standing genetic variation is formed through mutation because of the differences in the organisms of a population.
Phenotypes that indicate the physical appearance of organisms change during mutation.
Gene flow is another channel for genetic change. It occurs when two populations with different allele frequencies unite in the same environment and then assume similar allele frequencies.
When mating occurs, the allele frequencies of these populations can assume similarity.

Why / how does hydrogen bonding help ice cubes float?
Answer:
First, we must understand:
What is Hydrogen Bonding?
Hydrogen Bonding is the interaction between Hydrogen atoms, with their molecules, due to the fact that their (Hydrogen atoms and bonds) are weak that even the other types of bonds are stronger.
(The other bonds are: covalent and ionic bonds)
(Hydrogen bonds are weaker than the average bonds listed above)
If you are to take how and why hydrogen bonds effect/affect ice cubes, we would have to look at how ice cube are formed. If you know, ice cubes can be created due to low temperatures (cold temperatures) making water into a solid. When ice cubes form into a sold, the spacing of the molecules become further apart, creating the density of the overall ice cube lighter than it was allowing it (ice cubes) to float.
Why does temperature not change during phase change?
Answer:
during phase change, the energy supplied is used only to separate the molecules,no part of it is used to increase the kinetic energy of the molecules. So its temperature will not rise, since kinetic energy of molecules remains the same.

Plants release oxygen into the
atmosphere by...
A. Splitting apart water molecules
B. Splitting apart carbon dioxide
C. Attaching water together
D. Attaching oxygen together
Answer:
A
Explanation:
Plants use water in the process of photosynthesis, (to make food) but they don't need all of it. They use carbon dioxide, the stuff people and animals breath out, and release oxygen for us to breath, then we breath out carbon dioxide again and the process happens again.
Fun fact: Did you know that rain forests make their own weather? Plants not only release oxygen into the air, but tiny droplets of water. (water vapor, and this part of the water cycle is called transpiration) Those droplets condense and form clouds. That's why it rains every day in tropical forests. Cool huh?
