Which of the following most significantly determines a community's access to potable water? a. access to clean raw water sources b. the availability of money c. local drought conditions d. the level of industrial development
The option that most significantly determines a community's access to potable water is the availability of money. Thus, the correct option is B.
What is Potable water?Potable water may be defined as drinking water that is utilized by living organisms mostly by humans for drinking and food preparation. It is the purest form of water.
The potable water considerably decreases from the environment due to various climatic as well as human activities. In order to access this water for drinking, communities, people, etc. have the availability of money in order to purchase this form of water.
Therefore, the option that most significantly determines a community's access to potable water is the availability of money. Thus, the correct option is B.

In a certain population of rabbits, the allele for brown fur is dominant over the
allele for white fur. If 20 out of 100 rabbits have white fur, what is the allele
frequency for the recessive allele?
The Hardy-Weinberg equation is:
[homozygous dominant]? + 2[heterozygous] + [homozygous recessive]? = 1
A. 0.45
B. 0.80
C. 0.89
D. 0.65
In a certain population of rabbits, the allele for brown fur is dominant over the allele for white fur. If 20 out of 100 rabbits have white fur, the frequency of the recessive allele (b) is 0.45. Therefore, the correct statement is option A.
What is Hardy-Weinberg law?Hardy-Weinberg law represents the relationship between the allele frequency and genotypes present in the population.
If the allele controlling brown fur is dominant over the allele controlling white fur, the Hardy-Weinberg equation can be used to calculate the frequency of the recessive allele.
Let the frequency of the dominant allele (B) is denoted by p and the frequency of the recessive allele (b) be denoted by q. If 20 out of 100 rabbits have white fur, which means that the frequency of the bb genotype is 20/100 or 0.2.
Using the equation, we know that: p^2 + 2pq + q^2 = 1
where p^2 represents the frequency of the BB genotype, 2pq represents the frequency of the Bb genotype, and q^2 represents the frequency of the bb genotype.
By substituting the knowing values, the value of q can be calculated:
0.2 = q^2
q = sqrt (0.2) = 0.45
Therefore, the frequency of the b recessive allele is 0.45.

Which process is defined as breaking down rocks into smaller pieces without changing the rocks' compositions?
erosion
oxidation
chemical weathering
mechanical weathering
Answer: Mechanical weathering
Explanation: Mechanical weathering breaks rocks into smaller pieces without changing their composition. Ice wedging and abrasion are two important processes of mechanical weathering. Chemical weathering breaks down rocks by forming new minerals that are stable at the Earth's surface.
Breaking down rocks into smaller pieces without changing the rocks' compositions is called mechanical weathering.
A rock refers to a solid mass which may be found above or below the ground. Rocks are the source of soil. Soil is formed when a rock is broken down. The process of break down of a rock is called weathering of rock.

Which would be the best way to measure the amount of loose rabbits on a farm?
A) count them all
B) Trap-mark-release
C) Sample count
D) Estimated guess
Answer:
Estimated Guess so D because if there are more then 10 rabbits you do not want to count every single one. So you would look at how many five are and see how many groups look like about 5 and then guess from there. So an estimated guess would quickly and easily get you a decent amount close to counting them.

Is it the male or female that determines the sex of a zygote? Based on chromosomes, how do we know this to be true
Answer:
The male
Explanation:
A female always gives one X chromosome, a male can give either an X or a Y. If a zygote receives an X from its father and another X from its mother, it will be female. If a zygote receives a Y from its father and an X from its mother it will be male. Because the mother only has one option of chromosome to give, her chromosomes will not effect the gender of the zygote.

navigate?
Answer:
Their vision underwater is better than a humans, but inferior on land. Lenses are enlarged and almost round, adapted for focusing on light that is refracted upon entering water.

These areas include plants that do not go into a dormancy, like in New England, and a significant percentage of global rain forests. Would might be the global result as it relates to: photosynthesis rate, amount of atmospheric carbon dioxide, and ecosystem balance.
Answer:
Yes, it affects photosynthesis rate, amount of atmospheric carbon dioxide, and ecosystem balance.
Explanation:
Plants have the ability to clean the environment by absorbing carbondioxide gas during the process of photosynthesis. These plants are the important part of ecosystem and their removal causes imbalance of ecosystem. These plants provide habitat and food etc. If plants were killed because of fungal attack so decrease occurs in rate of photosynthesis, concentration of carbondioxide gas in the atmosphere and disturbed the balance of ecosystem.
