in recent years much of califorinia has had drought conditions much of our food comes from califorinia and there are many growing cities in that state what do you think has happened to the ground water supply as droughts have occured there explain how a diversion system could be useful califorinia including the parts of such a system
Answer:
The level of ground water decreases.
Explanation:
Due to drought condition, the level of ground water decreases because of pumping of water for the irrigation purpose. Huge amount of water is required to irrigate a large area of California and in the drought conditions ground water is the only solution for this problem. The diversion system will be useful California by diverging river into these drought affected areas in order to fulfill the need of water for growing crops so we can conclude that this diversion system helps to fulfill the necessity of water during drought situation.

20 POINTS!!!!!!!!!!!!!!
Answer:
Its a substitution mutation because one of the specific base, G is replaced by A.
This is a Point Mutation because Point mutation brings changes in the structure of a gene because of the substitutions with another base pair. Like in this case, G is substituted by A. In case of frameshift mutations, there is a change in the number of nucleotides due to either insertions or deletions of the nucleotides, which is not in this case.
Answer:
Its a substitution mutation because one of the specific base, G is replaced by A.

According to the World Population Growth graph, which best describes the human population growth after the Industrial Revolution?
Slow growth
Exponential growth
Negative growth
Zero growth
Answer:
negative
Explanation:
According to the World Population Growth graph, the human population growth after the Industrial revolution will be exponential growth. Thus, the correct option will be B.
What is the Exponential growth?Population growth can be defined as the annual increase in the population size of a species. Population growth is the difference between the total births less the total deaths and the difference between immigrants less the emigrants, in a given country, territory or a geographic area at a given year.
Exponential growth of a population is a function which shows an increase within a population that occurs at the same rate throughout the time period. When different populations experience doubling or tripling in numbers, then we can assume the data increases exponentially through the time. The opposite of exponential growth is exponential decay of the population, where the data shrinks rather than it grows.
Therefore, the correct option will be B.

What do plants use to make up their structure?
Answer:
Molecules of glucose join together to form cellulose. Next, glucose molecules combine to form long chains called cellulose. Cellulose is then used to build plant structures, like cell walls. As more cells divide, the plant's leaves, stems, and roots can grow larger.

How do underwater mountain ranges form?
Answer:
They are formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.

How do the plants depend on the animals for their survival give three examples
PLEASE HELP!!!!!!!!!!
Answer:
Plants provide animals with habitat and produce oxygen, which the animals use to survive. Animals decompose and become natural fertilizer plants until they pass. Animals provide fertilizer, pollinate plants, and disperse seeds. Plants are also beneficial for animal homes since many species live in close proximity to plants.
Explanation:
Answer:
Plants depend on animals because most of them decompose other dead non living things into our soil. They give animals air and to humans as well.
They also depend on each other for food.
They depend on each other for shelter. For example an insect uses a tree branch as shelter and protects it in return to the tree branch.

Which of the following is true of genetic drift?
It can decrease genetic diversity in a population.
It plays a much larger role in determining the genetic makeup of populations than
natural selection.
It is necessary in order for a population to be in Hardy-Weinberg equilibrium.
It can increase genetic diversity in a population.
The statement which is true about Genetic drift is that it can decrease genetic diversity in a population. Thus, the correct option for this question is A.
What is Genetic drift?Genetic drift may be defined as a type of evolutionary force that significantly involves the mechanism of evolution in which the allele frequency of a population may change over generations due to chance or sampling error.
The process of genetic drift occurs in all populations of non-finite size but its effects are strongest in the smallest populations. It is considered an assumption under the Hardy-Weinberg equilibrium. So, option C is eliminated.
The concept of the founder effect and genetic bottleneck always decreases the genetic diversity among the population. So, option D is eliminated.
Therefore, it can decrease genetic diversity in a population is that statement that is true about Genetic drift. Thus, the correct option for this question is A.

The main difference between macroevolution and microevolution is _____.
Select one:
a. the time frame of the evolutionary process
b. the species that evolve during each
c. that microevolution is only for small organisms, and macroevolution is for large organisms
Answer: c. that microevolution is only for small organisms, and macroevolution is for large organisms
Explanation:
Evolution can be defined as the gradual changes that occur in a population of a species or in an individual which supports its survival in the changing environment. Microevolution can be defined as the changes that occur during lifetime in an organism, whereas multiple changes occurring in the organisms over multiple generations. The microevolution is effective over small organisms like insects whereas macroevolution works on large organisms like whale. As the scale of evolution is low in microevolution as small number of changes occur whereas in case of macroevolution the scale of evolution is high so more changes will occur multiple times in an organism.
Answer:
the correct answer is - the species that evolve during each

In Mendel's experiments, a trait that disappeared in the F1 generation but reappeared in the F2 generation was always a
Answer: A trait that disappeared in the F1 generation but reappeared in the F2 generation was always a RECESSIVE TRAIT.
Explanation:
The basic laws of genetics were laid down by an Australian monk in 1866, Gregor Mendel. From the results of his experiment, Mendel came to certain conclusions which are referred to as the Mendel's Laws of Heredity one of which includes the Law of Segregation of genes.
The Law of Segregation states that:
--> the hereditary characters of an organism are determined by genes
--> a gene for a character may have alternative forms ( alleles) which express the character in different ways;
--> if a diploid organism has two different alleles ( heterozygous) for a character, one allele may be dominant, dictating the expression of the character to the complete exclusion of the other ( the recessive allele).
Furthermore, Mendel's experiments can be proven by the study of a single- factor inheritance pattern. This is achieved by crossing a pure stock of white- flowered pea plants and red - flowered ones. The offspring of this cross are all red flowered pea plants. They form the F1 GENERATION.
Since only red flower colour is seen in the F1 generation, we say the the red flower form of the character is dominant. White colour, which does not show up in the F1 generation, but reappear in F2 GENERATION when F1 GENERATION is crossed, is said to be the recessive form of the character.
Therefore, this implies that the recessive traits can skip a generation to appear in future generations according to Mendel's experiments.
Answer: Yea it was Recessive.
