An unusually cold winter causes the squirrel population to decrease. This is an example of temperature as a
A. Carrying capacity
B. Limiting factor
C. Climax community
D. Pattern in space
Please and answer thank you!
Answer:
Most likely B
Explanation:
A - Carrying capacity is the amount of a species that can live in a given area with the given resources, weather does not apply.
B - Limiting factors are things such as food, mates, and competition with other organisms for resources, which can limit the maximum population. Temperature can be applied here, it is the best option.
C - Climax community is when an area's ecosystem is stable, so the term makes no sense used here.
D - To be honest I have no clue what this is. But making an assumption from the term, the winter being "unusually cold" does not make it a "pattern". So I don't think it's this option. I could be wrong, but I assume this is not the right choice.

What determines the shape of the active site?
The shape of the active site in a given enzyme is determined by the amino acid residues of the protein and the interaction between such amino acids and also molecules in the physiological conditions of the surrounding media.
What is the active site in a given enzyme protein?The active site in a given enzyme protein is the molecular domain in the enzyme that binds to the substrate in a chemical reaction in order to form the enzyme-substrate complex that will be converted into products. The shape of the active site in the protein enzyme also depends on the amino acids in the domain that binds to the substrate and also to the molecular interactions.
Therefore, with this data, we can see that the active site in a given enzyme protein is dependent on the amino acids in the protein and their interactions.

4. How did the harnessing of electricity transform American business?
Around 1900, organizational and technological advancements in electricity sparked a new industrial revolution. The appearance of enterprises and cities was altered by electrical illumination and motors.
Businesses were able to expand their locations and increase their productivity thanks to centrally produced electricity. These accomplishments depended on the development of massive interconnected systems, most of which were monopolies controlled by corporations.
Before the war, the electricity business grew slowly, but in the 1920s it truly took off and played a significant role in the economic growth.
It offered factories a low-cost, effective source of power. It allowed for the simultaneous use of numerous sophisticated machines, paving the way for the development of mass production methods.
Because it provided the power required in consumers' homes for the new mass-produced goods, such as vacuum cleaners, refrigerators, and washing machines, electricity also contributed to the economic boom.

why are the polio virus unable to reproduce if their DNA base sequence is different from the normal virus?
Answer:
When the virus infects a cell, the RNA genome enters the cell and programs it to make new virus particles. These virus particles are released from the cell and go on to infect new cells. In humans, poliovirus is ingested, and replicates in cells of the gastrointestinal tract.Poliovirus, the prototypical picornavirus and causative agent of poliomyelitis, is a nonenveloped virus with a single-stranded RNA genome of positive polarity. The virion consists of an icosahedral protein shell, composed of four capsid proteins (VP1, VP2, VP3, and VP4), which encapsidates the RNA genome (1).RNA viruses generally have very high mutation rates compared to DNA viruses, because viral RNA polymerases lack the proofreading ability of DNA polymerases. The genetic diversity of RNA viruses is one reason why it is difficult to make effective vaccines against them.

What is the structure of a nucleotide? What are DNA's four nucleotides, and how do they pair up?
Answer:
Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.
A scientist makes a claim that a chemical in household cleaners causes cancer. Which question should other scientists ask about the claim if they are using scientific argumentation?
A. Is there too much of the chemical present in the cleaner
B. Should the cleaner be taken off the market
C. Are there safer chemicals that could be used in the cleaner?
D.are there other possible causes of cancer?
D. are there other possible causes of cancer?
Scientific argumentation involves testing hypotheses through rigorous experimentation and examination of evidence. In this case, before drawing any conclusions about the relationship between the chemical in the household cleaner and cancer, other scientists would want to examine whether there are other possible causes of cancer that should be considered. The scientist who made the claim would need to show through experiments and studies that the chemical in question is the cause of cancer and not some other variable that was not controlled in the study. And therefore, evaluating the evidence and testing the hypothesis is the fundamental part of scientific argumentation.

Answer:
Option 2 is not true (Cellular respiration occurs in the chloroplast in plant cells)
Explanation:
Photosynthesis occurs in the chloroplasts, whereas cellular respiration occurs in the mitochondria. Photosynthesis makes glucose and oxygen, which are then used as the starting products for cellular respiration. Therefore, cellular respiration takes place in the mitochondria in plants, not in chloroplasts.

rural homes
city streets
agriculture
suburban
development

coal-burning power plant
factory
Answer:
The two point sources of water pollution in the image are coal-burning power plant and factory.
Explanation:
Pollution refers to the release of waste and harmful substances to the environment. Substances which are harmful to the environment are known as pollutants.
Water pollution involves the contamination of water by pollutants making it unfit for human use such as such for drinking or cooking or for other uses.
The source of pollution water bodies have been divided into point and non-point sources of water pollution.
Point sources release pollutants from a single source and are transported directly through media such as a discharge pipe. The main point source of water pollution are factories and sewage treatment plants.
Nonpoint source pollution comes from various sources usually a combination of pollutants from a large area rather than from a specific sourc that can be easily identified such as discharge pipes. Most common is runoff water from city streets or agricultural settlements.

One way to determine the density of animals in an area is to use the mark-recapture technique. A number of individuals from a population are captured, marked so they are easily identifiable, and released back into the population. It's assumed that the captured and marked animals will randomly mingle with the rest of the population. Later, the population is re-sampled and the number of marked and unmarked animals is recorded. The following equation can then be used to estimate the size of the entire population. Gulded S Number of individuals marked in first catch Total population size, N Number of marked recaptures in second catch Total number of second catch If 25 Prairie Dogs were captured, marked, and released back into their population, and then subsequently 135 Prairie Dogs were captured, of which 18 were marked, what is the approximate total population size, N?
Answer:
The approximate total population size, N = 188 Prairie Dogs
Explanation:
The equation of the mark-recapture technique of determining population density is given below:
Number of individuals marked in the first catch/Total population size, N = Number of marked recaptures in second catch/Total number of second catch
If 25 Prairie Dogs were captured, marked, and released back into their population, and then subsequently 135 Prairie Dogs were captured, of which 18 were marked
Number of dogs marked in first catch = 25
Number of marked recaptures in the second catch = 18
Total number of second catch = 135
Substituting the given figures and solving for N, the total population:
25/N = 18/135
18N = 25 × 135
18N = 3375
N = 3375/18
N = 187.5
Thus, the approximate total population size, N = 188 Prairie Dogs
Histone modification: is fixed; once a histone is modified, it stays that way and the genes with which it is associated are turned on or off permanently. is random and independent of the environment or cell type. is fixed, but this has no effect on whether genes are expressed. can change over time in response to environmental cues, allowing genes to be turned on or off as needed. can change over time in response to environmental cues, but this has no effect on gene expression.
Answer:
The correct answer is ''can change over time in response to environmental cues, allowing genes to be turned on or off as needed.''
Explanation:
Histones are a family of proteins involved in compacting DNA into structural units called nucleosomes. Histone modifications occur in response to environmental conditions, and modulate the structure of chromatin, that is, they alter the structure of nucleosomes and therefore chromatin, and thus activate the transcription process, in which the chromatin is in the euchromatin state (loose conformation, in which the DNA information can be read), or "off" state, in which the chromatin adopts the heterochromatin conformation (compact conformation, which prevents reading), respectively. These post-translational modifications are mainly acetylation, methylation, phosphorylation, although there are many others. These make up the “histone code” that can change the expression pattern of some genes by modifying the chromatin structure, activating or silencing these genes.
Roger Sperry's chemoaffinity hypothesis Group of answer choices is supported by the orderly reinnervation of the frog optic tectum by regenerating retinal ganglion cells. was based upon his discovery of cell adhesion molecules in the optic tectum. relies on the random innervation of the optic tectum by retinal neurons correctly predicted that each optic tectal neuron-retinal axon pair would have a unique molecular lock-and-key recognition signal.
Answer:
is supported by the orderly reinnervation of the frog optic tectum by regenerating retinal ganglion cells
Explanation:
In vertebrates, the optic tectum represents the major part of the midbrain (mesencephalon), which is involved in the development of motor skills such as body movement, eye movement, vision, hearing, etc. In lower vertebrates such as, for example, frogs, the primary target of the optic nerve fibers (i.e., retinal ganglion cells) is the optic tectum, which is responsible for the visually guided behavior. Roger Sperry was a neurobiologist and pioneer brain researcher who won the Nobel Prize in Medicine for his investigations in neuroscience and experimental neurology. In 1940, R. Sperry made different experiments involving the visual system of frogs and he observed that when optic fibers are damaged they grow back to their original localization in the optic tectum in order to re-establish the original set of neural networks. From this observation, R. Sperry proposed his chemoaffinity hypothesis, which states that neurons have individual identification tags that specify synaptic networks.
