Why are zebra mussels a problem in the Great Lakes but not in the lakes systems where they came from?
Answer:
B. They have natural predators in the other lakes.
Explanation:
I'm pretty sure that's it, because if it's the lakes they originally came from, then they'd have predators to even their population out.

How does abnormal development take place in man?
Answer:
lol that's a hard question idk
Abnormal development is present when development of a person occurs in an unexpected way and exhibits an unusual pattern of behavior, emotion, or thought. It can occur at any stage of development. Symptoms of abnormal development include a disturbance in behavior, thought, or emotion.
As Darwin was developing his ideas about evoution, he applied ideas from many fields, including geology, economics, and biology. Why was this approach important?
Answer:
Explanation:
Darwin's use of many different fields of study including geology, economics, and biology was incredibly important as it allowed him to make connections between them that ultimately led to ground breaking discovery. Such as animals that that migrated to different areas and were interconnected through their geological footprints that were left behind.
Answer:
Darwin's theory of natural selection is important because it enables us to understand the forces driving evolution in living organisms. This evolutionary mechanism may also be used in different research fields ranging from molecular biology to economy.
The evolution theory states that the organisms that are better adapted to the environment have more chances to survive and to reproduce, thereby perpetuating their own genes in future generations. This idea of selection can also be applied to other disciplines. For example, in the economics field, it has been proposed that Darwin's theory may explain why those traits related to morality (such as fairness, honesty and integrity) which are beneficial for one particular group but not for the individual are not selected in real life.

What are the three types of muscle fibers? A)smooth, intermediate-twitch, cardiac B)slow-twitch, intermediate-twitch, fast-twitch C)Slow-twitch , fast - twitch , involuntary Can someone please help me with this
Answer:
The other person is correct I did a test on plato and got it right. Shoutout to whoever it was that answered the question, I thank you!
Explanation:
The three types of muscle fibers are B) slow-twitch, intermediate-twitch, fast-twitch.
What are these muscle fibers?Slow-twitch fibers are also known as type I fibers. They are fatigue-resistant and have a high oxidative capacity. Slow-twitch fibers are used for activities that require endurance, such as long-distance running or swimming.
Intermediate-twitch fibers are also known as type IIa fibers. They are less fatigue-resistant than slow-twitch fibers, but they have a higher oxidative capacity than fast-twitch fibers. Intermediate-twitch fibers are used for activities that require both endurance and power, such as sprinting or jumping.
Fast-twitch fibers are also known as type IIb fibers. They are the least fatigue-resistant of the three types of muscle fibers, but they have a high glycolytic capacity. Fast-twitch fibers are used for activities that require short bursts of power, such as sprinting or weight lifting.

How far back are ancestors ?
Answer:
The Last Universal Common Ancestor (LUCA) is the most recent common ancestor of all current life on Earth, estimated to have lived some 3.5 to 3.8 billion years ago
pls mark brainliest
Explanation:
Answer:
An ancestor, also known as a forefather, fore-elder or a forebear,[1] is a parent or (recursively) the parent of an antecedent (i.e., a grandparent, great-grandparent, great-great-grandparent and so forth). Ancestor is "any person from whom one is descended. In law the person from whom an estate has been inherited."[2]
Two individuals have a genetic relationship if one is the ancestor of the other or if they share a common ancestor. In evolutionary theory, species which share an evolutionary ancestor are said to be of common descent. However, this concept of ancestry does not apply to some bacteria and other organisms capable of horizontal gene transfer. Some research suggests that the average person has twice as many female ancestors as male ancestors. This might have been due to the past prevalence of polygynous relations and female hypergamy.[3]
Assuming that all of an individual's ancestors are otherwise unrelated to each other, that individual has 2n ancestors in the nth generation before him and a total of 2g+1 − 2 ancestors in the g generations before him. In practice, however, it is clear that most ancestors of humans (and any other species) are multiply related (see pedigree collapse). Consider n = 40: the human species is more than 40 generations old, yet the number 240, approximately 1012 or one trillion, dwarfs the number of humans who have ever lived.
Some cultures confer reverence to ancestors, both living and dead; in contrast, some more youth-oriented cultural contexts display less veneration of elders. In other cultural contexts, some people seek providence from their deceased ancestors; this practice is sometimes known as ancestor worship or, more accurately, ancestor veneration.

Which of the following best describes the structural relationship between genes, chromosomes and DNA?
A.Genes consists of two long strands of chromosomes, and each of these two strands consists of molecules called DNA.
B.Each DNA molecule consists of a number of pairs of genes, and each pair of genes on the DNA molecule is made up of chromosomes.
C.Each chromosome consists of number of DNA molecules, and each DNA molecule is made up of one to four different genes.
D.Each chromosome consists of a single long DNA molecule, and each gene on the chromosome is a particular segment of that DNA.
Answer:
D.Each chromosome consists of a single long DNA molecule, and each gene on the chromosome is a particular segment of that DNA.
Explanation:
A closed DNA molecule contains two strands of linear nucleotide sequences, and both DNA strands contain genes. These genes are DNA sequences that may be transcribed in messenger RNAs (mRNAs).
The cell nucleus contains chromosomes in which the double-stranded DNA molecules are packaged by specialized proteins (histones). Moreover, there are organelles (mitochondria and chloroplast) that also contain genes which are transcribed in an analog mode to genes contained in the nuclear chromosomes.
The correct statement is "Each chromosome consists of a single long DNA molecule, and each gene on the chromosome is a particular segment of that DNA"
Chromosomes are condensed strands or rings of DNA and have a double structure, composed of chromatids, in these the genes are located, in the same position with respect to their homologous.
Genes are found within chromosomes (which in turn make life in the nucleus of our cells).Each gene occupies a specific position, called a locus, along the gigantic chain of sequences that makes up DNA.Therefore, we can conclude that chromosomes are structures composed of DNA and genes are short segments of DNA, which is found within the chromosome always located in the same place.

The definition of theory says that it is a hypothesis or group of hypotheses. In your own words, explain why a theory is also a hypothesis, using the definitions as a starting point. In your answer, provide an example of a theory that is a hypothesis supported by repeated experimentation.
Answer:
An in-depth illustration of a natural process that takes place in nature is termed as a scientific theory. After performing a scientific method the formation of a theory takes place. The generation of a good scientific theory takes place after proving, testing, and linking different kinds of ideas that are not just assumptions.
A theory can also be considered as a well-illustrated hypothesis as a scientific theory is a deeply illustrated and a well-substantiated idea that overpowers the restricted illustration of a suggested hypothesis. A theory is an amalgamation of various ideas.
The theory of relativity, which was postulated by Einstein in 1915 is a good illustration of a scientific theory that has been repeated several times. After the emergence in 1915, the theory was again examined in 1919 during the solar eclipse and was afterward examined and tested by different other scientists.

A response is a _______________ to a stimulus. • A stimulus is anything that can cause an individual to respond or react. • Stimuli can be _________ or ____________ .
Answer:
A response is a _reaction to a stimulus. • A stimulus is anything that can cause an individual to respond or react. • Stimuli can be _internal or external.
Explanation:
A change in the cellular make up of an organisms due to response or reaction to a stimulus is called a response. This response can be due to a stimulus inside the body , or due to effect of an external ( stimulus) object on the body-stepping on a sharp pin.
In either cases, the stimulus is receive by the receptors, which transfer the stimulus through the sensory neuron to the inter neuron in the CNS, for the motor neuron to bring an effective response at the effectors.
A lion has sharp pointed teeth while a buffalo has flat, broad teeth. Why do you think the teeth in these animals differ?
Answer:
Explanation:A carnivor will have sharp pointed teeth because a lion eats meat and needs to rip it apart whereas a buffalo eats leaves and plants (herbivores)so they have flat teeth as leaves are easier to bite and chew than meat.

Estelle makes a Venn diagram to compare the fast- and slow-flowing areas of rivers and streams.
Which label belongs in the region marked X?
Fewer plants
Warmer
Cloudy water
Less oxygen
Image is not provided in the question, so the image is attached below.
Answer:
Fewer plants
Explanation:
The region X in Venn diagram represents fewer plants in the region.
As the regions marked X represents fast-flowing areas of rivers and streams which can be possible if the flow of water get less obstruction in its way, so if their will be fewer plants, river will get less resistance and can flow faster.
Other option do not affects the flow of water.
Hence, the correct option is fewer plants.
Answer:
Because lakes are often large and deep, little sunlight reaches the bottom. The lack of sunlight and resulting cold temperatures limit the number of plants that can grow beneath the water. Therefore, most of the plant growth in lakes is limited to shallow areas near the shore, where there is a lot of sunlight.
Explanation:
Students recorded their heart rates in several situations. Which of the following data collected would illustrate a feedback response?
A)All students had a constant heart rate while they were at rest.
B)All of the student's heart rates are within a certain range.
C)The heart rates of males were higher on average than females.
D)Every student had an elevated heart rate during exercise.
Answer: Option D.
D)Every student had an elevated heart rate during exercise.
Explanation:
The students have elevated heart rates during exercise. This is because during exercise, muscles need 3 times or four times oxygen when you exert yourself. During exercise, the heart beat faster which make for quicker pulse so that more blood is pump out of you body. The heart beat both stronger and faster to increase cardiac output during exercise.
Cardiac output is stroke volume × heart rate.
Stroke volume is the amount of blood pumped by the heart.when the heart beats.
Heart rate is the number of times heart beats per minutes.
