How does introduced species harm our planet?
Please someone answer this
ASAP!!!
Introduced species can harm our planet because in some regions of the world we are not prepared for their type of species, which can all in all cause damage.
Answer: alteration of the ecosystem
Explanation:when a new specie is introduced into the ecosystem it may have profound affects in the ecosystem and may also be called an invasive specie.
The affects that it may have on the ecosystem include
1.outcompeting the native specie and sometimes even leading to their extinction because the new specie may be modified in such a way as to have better chances of survival in the ecosystem because of their evolved genetics e.g : the new specie may encounter a native and non evolved specie of the ecosystem and compete with it for survival leading to reduction and even complete eradication of the native specie

Which part of a mushroom can you see above the ground?
Answer:
The correct answer is reproductive part.
Explanation:
The mushroom belongs to the family of fungus. It is composed of two parts one underground part called as mycellium and the other part which can be seen above the ground. This part is the reproductive part of mushroom which is often edible. The other parts of the mushroom includes stem, hypae, volva, spores, gill, ring cap. There are variety of mushrooms available but all the forms are not eatable some of them are poisonous to human health.
How do invasive species disrupt an ecosystem? Describe at least one example of when invasive species have disrupted an ecosystem. Your example could be a plant, animal, fungus, ext. (please please please help!!)
Answer:
Explanation:
I think one of the most invasive species is perhaps the Dandelion. Who hasn't had a fit when we see them change from yellow to gray. The yellow is pretty, but the gray means it is ready to spread its seed to create more trouble.
Dandelions can be killed with herbicides, but I think you'd be as well off putting up with the dandelion. The herbicides have an unproven effect on our health.
The dandelion was introduced into the Americas in the mid 1600s and was used as food and had medical properties. Since then, because it has no common enemy in nature, it has spread the entire width of the continent. Rather amazing, I think.
Which of the following is not true of most sex-linked traits?
A. Located on the X chromosome
B. Located on the autosomes
C. Usually recessive
D. Usually seen in males
Answer:
a
Explanation:
Sex-linked traits refer to those associated with genes located on sex chromosomes. They are typically recessive and more common in males. The statement that these traits are located on autosomes, which are non-sex chromosomes, is incorrect.
Explanation:In studying genetics, we learn that sex-linked traits are primarily associated with genes located on sex chromosomes. These traits, more often than not, are recessive and more common in males, as they carry only one X chromosome and, therefore, express all traits that are linked to this chromosome.
Yet, the statement that sex-linked traits are located on autosomes is not true. Autosomes are all the other chromosomes that are not sex chromosomes. Hence, the answer to your question is option B: Sex-linked traits are not located on the autosomes.

volume
fibers
envelope
Figure 10-5
Structure A in Figure 10-4 is the centrioles. role does structure A play in mitosis is: (c) connect to spindle fibers
Centrioles are paired organelles that are found in the cytoplasm of eukaryotic cells. They are composed of microtubules, which are long, thin filaments that form the structural framework of the cell. During interphase, the centrioles are located near the nucleus and are surrounded by a cloud of protein called the centrosome.
As the cell progresses into mitosis, the centrioles replicate and move to opposite poles of the cell. This process is called centrosome separation. The centrosomes act as organizing centers for the spindle fibers, which are microtubules that extend from the centrosomes and attach to the chromosomes. The spindle fibers play a crucial role in separating the chromosomes during mitosis.
The history of Taurus
Answer:
The zodiacal sign of Taurus does not coincide with the constellation of Taurus. It is a continuation of the sign of Aries and represents the second 30 degrees of the zodiacal circle. The sign of Aries represents the beginning of spring and with it the beginning of life, while Taurus is a fixed sign that continues what Aries has started. Life is in full bloom in the sign of Taurus.
The stars in Taurus constellation host two open clusters, the Pleiades and the Hyades and are mostly located at the end of the sign of Taurus and the beginning of the zodiacal sign of Gemini. In the Early Bronze Age it marked the location of the Sun during the spring equinox, just like the constellation of Aries represented the equinox over 2000 years ago. The constellation of Taurus was linked to it 5000 to 1700 BC, before the precession of the equinox moved our perspective to the sign of Aries.

Can a tornado pick up a person and send it to another island?
Answer: almost imposiable
Explanation: If you do happen to get picked up a tornado the longest time you will stay in it is approximately 5 minutes before it throws you out of it. If you did so happen to be swept in a tornado near a island it is possiable, but tornados over water die very very fast so this is very unlikley.
Hope this helps
Answer:
Nope.
Explanation:
Now I don't know anything about much about tornado's. But I'm pretty sure it won't pick up that person and send it to another island. I don't think the tornado have enough force to throw the person to another island. It will, however, send that person on another area maybe close to the tornado area. But yet again I don't the tornado have the abilty to do that.

Answer:
D. Protists
Explanation:
Kingdom protista is composed of mostly unicellular organisms, but they do include some multicellular organisms. Like your problem says, eukaryotes that do not fit in other kingdoms are placed in this kingdom. As a result, even members of this kingdom do not share many similarities, as the organisms here are diverse.
The answer is D. Protists

What evidence makes scientists think that land plants evolved from green algae
Answer:
Because the algea was not strong enough yet to live on its own and had to stay close a water source, where it could get water and sunlight without doing any work.
Explanation:
Scientists believe that land plants evolved from green algae due to shared physical traits, biochemical pathways, and their common monophyletic heritage. These include similar mechanisms of cell division, storage of starch, the presence of chlorophyll as a photosynthetic pigment, and being part of the same photosynthetic lineage, the Archaeplastida.
Explanation:The evidence that leads scientists to believe that land plants evolved from green algae is rooted in various shared characteristics and evolutionary lineage. Green algae, especially the Charophytes, share several traits with land plants, such as having chlorophyll a and b as photosynthetic pigments, cellulose cell walls and starch as a storage molecule. Another crucial point to note is a common mechanism of cell division and significant biochemical pathways.
Furthermore, evolutionary thought indicates that all plants, including green algae and land plants, are monophyletic, meaning they descend from a common ancestor. The transition from water to land posed significant challenges to plants in the form of avoiding drying out, spreading reproductive cells in air, developing structural support, and capturing sunlight. Characteristics like these were developed during evolution by both green algae and land plants.
Lastly, the Archaeplastida, which includes green algae and land plants, became photosynthetic through an endosymbiotic relationship with a green, photosynthetic bacterium around 1.65 billion years ago. This lineage evolved into what we know today as red and green algae, and eventually land plants such as mosses, ferns, gymnosperms, and angiosperms. These shared traits and the evolutionary history demonstrate the strongly supported theory that land plants evolved from green algae.

Why do geese fly together in a V formation?
Explanation:
Geese fly together in a v formation.
Geese fly together because when the first goose flaps it's wings it creates an upward force which make it easier for the second goose to fly.

How is a scientific law different from a scientific theory?
A. A theory becomes a law after a long period of time has passed.
B. theory is why something happens and a law is how something happens.
C. A theory cannot be disproved but a law can be disproved.
D. A theory is used for biology and chemistry and a law is used for physics.
A scientific law is a concise statement that describes a pattern or behavior in nature, while a scientific theory is a more complex and dynamic explanation of a group of related phenomena.
Explanation:A scientific law is a concise statement that describes a pattern or behavior in nature that is supported by evidence and repeated experiments. Laws are often expressed in the form of a single mathematical equation. On the other hand, a scientific theory is a more complex and dynamic explanation of a group of related phenomena. Theories attempt to explain why nature behaves the way it does, while laws describe what happens.
Final answer:
A scientific law describes how something happens using a concise pattern in nature, often expressed as a mathematical equation, like F = ma for Newton's second law of motion. A scientific theory is a more complex explanation of why phenomena occur, such as the Theory of Evolution or the Theory of Relativity, and evolves over time as new evidence is found.
Explanation:
The question on how a scientific law is different from a scientific theory can be best answered by choice B: A theory explains why something happens and a law describes how something happens. A scientific law uses concise language to express a generalized pattern observed in nature, often supported by significant scientific evidence and can be demonstrated through repeated experiments. Laws can typically be distilled into mathematical equations or principles. An example is Newton's second law of motion, represented by the equation F = ma, which describes the relationship between force, mass, and acceleration.
On the other hand, a scientific theory is more complex and dynamic, providing an overarching explanation for a group of related phenomena based on a body of evidence. Theories, such as the Theory of Evolution or the Theory of Relativity, are comprehensive and explain why things occur as they do in nature. They are not concise enough to be summarized into a single equation or statement. Unlike a law, a theory does not transform into a law over time; they continue to evolve as new evidence emerges.
A population of 20 monarch butterflies colonizes a meadow. The meadow's carrying capacity for monarch butterflies is 5,000 individuals. What statement best describes the growth of the population of monarch butterflies after the meadow is colonized?
A.
The population grows at a constant rate until it approaches 5,000 individuals, and then its growth rate increases.
B.
The population grows exponentially until it approaches 5,000 individuals, and then the population size begins to decrease.
C.
The population grows exponentially until it approaches 5,000 individuals, and then its growth rate decreases.
D.
The population grows at a constant rate until it approaches 5,000 individuals, and then the population size remains stable.
Answer:
The only possible answer is D, which states that the population will reach 5000 and after that the growth will stabilise (exactly what would hapen in a logistic growth).
Hope This Helps! Have A Nice Day!!
Answer:
The correct answer is option D, that is, the population grows at a constant rate until it approaches 5,000 individuals, and then the population size remains stable.
Explanation:
The maximum capacity of the monarch butterfly, which can thrive in the meadow is 5000, which signifies that the population of twenty butterflies will continue to grow unless and until it attains the population of 5000.
In case if the growth of the population takes place exponentially, then there would be an end and the limit of 5000 would not have any significance. However, if the growth of the population takes place logistically, then the end of the growth would be the same as the limit that signifies that the 5000 limits would exhibit significance.
Thus, the only probable answer would be option D, that is, the population will attain 5000 mark and post that the growth will become stable, which precisely takes place in a logistic growth.
