The San Marcos salamander, Eurycea nana, is a light reddish-brown translucent salamander about 2-5 cm in length. E. Nanais foundonly inSpring Lake and a portion of the San Marcos River.
Complete question:
The San Marcos salamander, Eurycea nana, is a light reddish-brown
translucent salamander about 2-5 cm in length. E. nana is found only in
Spring Lake and a portion of the San Marcos River.
Which human activity would most likely decrease the ability of the
salamanders to survive?
The addition of a new food source into the river that limits competition for
resources
Tourism that helps fund the educational programs related to river ecosystem
conservation
Public transportation that reduces the number of automobiles that contribute to
pollution runoff into the river
Increasing water consumption that decreases the flow of clean water from the
springs that feed the river
Answer:
Increasing water consumption that decreases the flow of clean water from the springs that feed the river
Explanation:
In this question we are required to state the human activity that may likely cause the reduction in the survival rate of the salamander.
the first three options in the question are not the answer to this question. this is because options 1,2,3 would have positive impacts on the Salamander. these positive impacts would increase the ability of the salamander to survive and not decrease it as the question says.
the correct answer is the last option. that is the 4th option. because it has to do with decreasing the amount of water that flows in to the Salamanders habitat by human activities. if humans increase water consumption, then the flow of clean water would reduce. This would then have a negative effect on the Salamander.

If a bat, an alligator, and a bird evolved from a common ancestor, what most likely can be concluded
A. They are able to survive changes in their environments
B. They live in the same part of the world
C. They have similar anatomical structures
D. They are in the same biological classification
If a bat, an alligator, and a bird evolved from a common ancestor, most likely can be concluded that they have similar anatomical structures. Thus, option C is correct.
What are the different structures of animals?Structures of animals that have different appearances and functions but seem to have evolved from the same body part in a common ancestor. This can be found in Cat's leg and human arms.The structure do not need to look the same or perform the same functions.
The analogous structure evolve in different species living in two different geographic location with similar environmental conditions. Thus, the analogous structures have similar function and purpose but since they have not evolved from the same ancestor their structure vary a lot for example – wings in both birds and butterfly are meant for flight but their structure is entirely different.
The arrangement of bones is identical in all three organisms. This effectively means that all these organisms gradually evolved from a common ancestor.
Therefore, If a bat, an alligator, and a bird evolved from a common ancestor, most likely can be concluded that they have similar anatomical structures. Thus, option C is correct.

Why were Wegener's ideas about continental drift initially rejected
Answer:
The main reason that Wegener's hypothesis was not accepted was that he suggested no mechanism for moving the continents.
Explanation:
It wasn't until 1928 that a Scottish Geologist, Arthur Holmes, came up with an explanation for why continents move. He believed that heat traps in the Earth caused convection currents. There were areas where fluids trapped beneath Earth's crust heat up, rise, spread laterally, then cool and drop back down. This hypothesis didn't have a wide acceptance either but was revived in the 1940s and 1950s when scientists started to learn more about the seafloor and the magnetic properties of oceanic crust.

Explain how mitosis maintains the chromosome number
of the original cells when forming new cells.
Relation between mitosis and chromosomes:
During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells. Because this process is so critical, the steps of mitosis are carefully controlled by certain genes. As they move, they pull the one copy of each chromosome with them to opposite poles of the cell. When mitosis is not regulated correctly, health problems such as cancer can result.When a cell divides by way of mitosis, it produces two clones of itself, each with the same number of chromosomes.

HELPPP!!! What would the mass of an artificial cell containing 20mL of a 25% sugar solution be after it was placed in a beaker containing a 30% sugar solution for 30 minutes? Remember to include units in your answer.
Answer: The sugar will move from the 50 % concentration to the 0 % concentration.
Explanation:
Dialysis is an analytical technique which uses a semipermeable membrane in order to remove the impurities from the body.
This technique is used when the kidney failure inside the body takes place. The kidney inside the body perform function of filtration, when kidney failure takes place then the dialysis is used.
In this case the tubing bag containing 0% sugar is put into a sugar solution having 50% solution.
After sometime the sugar will move from 50 % to 0% bag because of the phenomenon known as osmosis.
What happens to energy that is transmitted through or reflected off a material?
When light is transmitted through or reflected off a material, the light is converted into heat.
What is light?Light is an entity that make things visible to eyes. It is an electromagnetic radiation. It can not be produced or end, it's just converted into one form to another form.
The item may absorb the light wave, in which case its energy is changed to heat. The object might reflect the light wave. Additionally, the object might transmit the light wave. When this happens, things often selectively absorb, reflect, or transmit certain light frequencies.
The light is passed through some objects and do not get passed through some objects. The light that do not pass through an object is reflected back to the same place, but when it is not reflected, it converts into heat.
Therefore, the light is converted into heat when it is not reflected.

Which statement describes a law based on a tested hypothesis explains how the process occurs describes something about the natural world subject to change as new evidence is discovered
Answer:
based on a tested hypothesis
Explanation:
Laws are generally based on tested hypotheses.
Theories are first derived from repeatedly tested and proven hypotheses. Scientific laws are derived from theories that have been proven to be true over a wide range of phenomenon. Hence, laws are overwhelmingly proven facts that cannot be changed.
Scientific laws are internally consistent, compatible with evidence, and are testable against a wide range of phenomenon. However, they can be reviewed as more evidences emerge that have not been known before.

Compared with mitosis, the process of meiosis results in daughter cells that are-
A. haploid cells with the same number of chromosomes as the parent cells
B. haploid cells with a smaller number of chromosomes than the parent cells
C. diploid cells with a smaller number of chromosomes than the parent cells
D. diploid cells with the same number of chromosomes as the parent cells
Answer:
Explanation:
eAnswer: Haploid cells with a smaller number of chromosomes than the parent cell
Explanation: meiosis results in four daughter cells which are haploids. Haploids have half the number of chromosomes of the diploid parent cell.
Crossing over occurs during meiosis and leads to changes in the chromosomes. What type of chromosomes does crossing over produce?
1. Chromosomes containing DNA from two different parental chromosomes
2. Chromosomes identical in genetic makeup to the parental chromosomes
3. Chromosomes containing more genes with non recombinant chromosomes
4. Chromosomes carrying genes from one parent
Answer:
1.
Explanation:
because the DNA is being mixed up while crossing over
Crossing over occurs during meiosis and leads to chromosomes containing DNA from two different parental chromosomes, hence option 1 is correct.
What is meiosis?New allelic combinations are created in the daughter cells as a result of the exchange of genetic material between non-sister chromatids of homologous chromosomes during meiosis.
Homologous chromosomes couple along their lengths during meiosis, one from each parent. At locations known as chiasma, the chromosomes overlap.
The chromosomes split and reunite at each chiasma, exchanging part of their genes in the process. Genetic diversity comes from this recombination.
Therefore, the genetic complement in each daughter cell at the end of meiosis is best described as a haploid set of chromosomes resulting from chromosomal recombination between the parents.

You are comparing the density of sea water to the density of fresh water. (Remember,
density is mass divided by volume.) Describe how you could determine the density of
sea water, including the names of the equipment needed to make the required
measurements.
Answer:
To know and compare the difference between the density of the fresh water and salt water or sea water require a graduated cylinder, balance, and weighing machine. The graduated cylinders are the containers that have markings on them to measure the volume of the liquid.
First, fill the cylinder with 1000 ml of fresh water which is the measure of the volume. now weight the cylinder filled with the fresh water and then find the difference between filled and empty container divide the mass of the fresh water by its volume, the result is the density of fresh water.
Repeat the process with salt water or sea water. The answer would be sea water has more density than fresh water.
