What might happen to the Burmese python population over time as it reaches or
surpasses its carrying capacity in South Florida? How might other organisms in the
ecosystem be affected? What might happen to the population sizes of various types
of organisms in the Everglades?
Answer:
If the Burmese Python surpasses its carrying capacity, the other organisms might not have enough food, or there is barely a chance of survival for the pythons' prey. The population sizes of other organisms might go down, and go to..extinction :/.
Explanation:
If the Burmese Python exceeds its carrying capacity, other creatures may starve or the pythons' prey may not survive. Other creatures' populations may go extinct.
What is carrying capacity?The typical number of individuals belonging to a species that are found in a given ecosystem is one definition of carrying capacity. The population size of the species is restricted by environmental conditions such as the availability of sufficient food, shelter, water, and mates. In the event that these requirements are not fulfilled, the population will continue to decline until the resource levels recover.
Therefore, if the Burmese Python population grows above its carrying capacity, the other creatures in the area may not have access to enough food, and the prey of the pythons will have an extremely low chance of surviving. It is possible that the population sizes of other organisms will decrease, leading to their eventual extinction.

Before mitosis begins, which happens before the nucleus starts dividing?
The DNA replicates.
The cytoplasm separates.
The sister chromatids separate.
The homologous chromosomes cross over.
Answer:
The DNA replicates.
Before mitosis begins, the DNA replicates. During the S phase of interphase, which precedes mitosis, the DNA in the nucleus undergoes replication, resulting in the formation of identical sister chromatids.
This ensures that each daughter cell produced during mitosis receives a complete set of genetic information.
After DNA replication, the cell enters the mitotic phase, during which the nucleus divides and the replicated DNA is distributed to the daughter cells.
The cytoplasm separates during cytokinesis, which occurs after mitosis and is not directly related to events before nucleus division. The separation of sister chromatids occurs during anaphase of mitosis, not before the nucleus starts dividing.
Thus, the process of homologous chromosomes crossing over occurs during meiosis, not mitosis.

a) skeletal only
b) skeletal and smooth
c) smooth and cardiac
d) cardiac only
Which of the following are events following fertilization? (Check all that apply. There may be more than one answer). *
a) Embryo develops into the fetus
b) Zygote cell rapidly divides
c) Embryo embeds into uterine wall
d) Zygote travels down the fallopian tube toward the uterus
Storing hormones, smooth and cardiac muscles are the correct answers.
Storing hormones is not function of skeleton system. Skeleton system protects internal organs such as heart, kidney and lungs etc. It is also responsible for the movement of the muscles as well as produces blood cells because of the presence of bone marrow.
Smooth and cardiac muscles can contract without nervous system stimulation because they are involuntary Muscle which is beyond the control of the nervous system so we can conclude that storing hormones, smooth and cardiac muscles are the correct answers.

In the lab simulation, which color peppered moth was able to have the highest rate of survival on the dark bark?
During the Industrial Revolution, explain what caused the population of light-colored peppered moths to decrease and the population of dark-colored peppered moths to increase over time. Be sure to include how the ability to survive and reproduce impacts the process of natural selection.
Predict which color peppered moth would have a better chance of survival in your neighborhood? Explain why.
Answer:
conclusion
Explanation:
hope this helps
Answer:
1. What caused the tree bark to become darker than it was, was the soot from factories in the Industrial Revolution.
2. The light-colored peppered moths have a higher rate of survival on the light bark since it's the same color as it and can't be easily spotted.
3. The dark-colored peppered moths have a higher rate of survival on the dark bark since it's the same color as it and can't be easily spotted.
4. What caused the population of light-colored peppered moths to decrease was the color of the tree bark. The tree bark was dark from the soot from factories. If the tree bark was a dark color, then light-colored peppered moths are more easily spotted, and since the tree bark is a dark color the dark-colored peppered moths can hide more easily, and not be as spotted than the light-colored peppered moths.
5. You have to answer this question. If the tree bark is a dark color, then the dark-colored moths have a better chance of surviving, but if the tree bark is a light color, then the light-colored moths have a better chance of surviving.
Hitchhiker's thumb (H) is dominant to no hitchhiker's thumb (h). A woman who does not have hitchhiker's thumb marries a man who is heterozygous for hitchhiker's thumb. What is true of their offspring?
Answer:
There is a 50% chance the kids will have Hitchhiker's thumb
Explanation:
Because Hitchhiker's thumb is dominant and the woman doesn't have it it's safe to assume her genes for it are hh. In a punnet square it would look like

Sleet is precipitation made of small particles of ice. How does sleet form?
Answer:
Sleet is pellets of ice that form when snow falls into a warm layer and melts into rain. The rain then falls into a freezing layer of air that is deep enough to refreeze the raindrops into pellets. Sometimes the snow does not completely melt and the partially melted snowflakes refreeze into snow pellets.:
hope this helps!
Answer:
There must be a layer of air near the ground whose temperature is below freezing, where water turns to ice. Above this layer of freezing air must be a layer of warmer air. As snow falls through the warm air, it melts or partially melts into raindrops. It forms sleet before it reaches the ground.

Jacque is hiking in the mountains and sees a very large and colorful rock layer. It looks different than the surrounding rock layers. What is the best way for Jacque to investigate what the environment was like when this rock layer was deposited?
Jacque could measure the height of the rock layer.
Jacque could check if the rock layer has fossils in it.
Jacque could look at the color of the surrounding rock layers.
Jacque could chip off a chunk of rock from the rock layer and smell it.
Answer:
Check if the rock layer has fossils in it.
Explanation:
The rock layer from the inside out and the fossils will tell you how old the rock is.
Jacque could check if the rock layer has fossils in it, as the presence and types of fossils can often provide clues about the environment in which they were formed.
What can a rock layer tell about the environment?To investigate what the environment was like when a rock layer was deposited, there are several approaches that can be taken:
Look for clues in the rock layer itself: The rock layer itself can often provide clues about the environment in which it was formed. For example, the presence of certain minerals or fossil types can indicate the presence of specific conditions, such as warm or cold temperatures, or a marine or terrestrial environment.
Examine the surrounding rock layers: The rock layers above and below the rock layer of interest can provide additional context and clues about the environment. For example, if the surrounding layers are sedimentary rocks, such as sandstone or shale, it may indicate that the area was once covered by water.
Use rock dating techniques: As mentioned earlier, techniques like radiometric dating and relative dating can help determine the age of a rock layer and provide insight into the environment that existed at the time it was formed.
Conduct additional analyses: Depending on the type of rock and the questions being asked, it may be possible to conduct more detailed analyses, such as chemical or isotopic analyses, to gather further information about the conditions under which the rock formed.
Consider the current location of the rock layer: The current location of the rock layer can also provide clues about the environment in which it was formed. For example, if the rock layer is found in a mountain range, it may have formed in a tectonically active area, while a rock layer found in a flat, low-lying area may have formed in a more stable environment.
