how might a country run out of water
Answer
Along with decreasing rainfall comes rising temperatures. By 2050 the U.S. could be as much as 5.7°F warmer, and extreme weather events, such as heatwaves and drought, could be more intense and occur more frequently. As temperatures warm, evaporation increases, further decreasing water in lakes, reservoirs, and rivers.

You have learned that scientists have found physical evidence of the Flood. In this project you will think about Noah and his construction of the ark.
Pretend that you are a newspaper reporter, and you are able to interview Noah. Then write a newspaper article about your interview.
Answer these questions.
What kinds of questions would you ask him?
Write a news article on your interview with Noah. (100 words or more is fine)
Need help asap just answer write the article the first 1 i already answered just copy pasted the questions
Answer:
We got a chance to speak to Noah the Ark builder. Many people of the town have been wondering what Noah has been building lately. We asked him what was his objective and he said "A great flood like no other will come, water from the sea will fall from the air. Whoever is in the ark shall be safe. Two of each type of animal on earth shall come to my ark for shelter. The storm will be so great it will knock out all who does not inhabit the ark."It is hard to understand what he means by these statements but who knows maybe his boat will take him somewhere. The people of the town have been calling him insane, since no one would need a boat that big.
(I'm guessing that you mean the interview was before the flood since everyone died after.)

Read the following selection and answer the question. On a September day in 1999, people began to notice that Lake Jackson in the Panhandle region of northern Florida was shrinking. Within a few days, it was almost gone. A sinkhole had opened beneath the lake and drained it, along with all of its inhabitants including fish and alligators. As aquifers lose water, rock and soil layers can become weaker and less capable of supporting overlying layers of earth and any human structures built upon them. In such cases, the land surface above may subside, or sink. Sometimes subsidence can occur locally and suddenly in the form of sinkholes, which are areas where the ground gives way with little warning. Once the ground subsides, soil becomes compacted, losing the porosity that enabled it to hold water. Recharging a depleted aquifer may therefore become more difficult. Sinkholes occur when?
Answer:
Sinkholes occur when water from the groundwater has been removed in excess.
Explanation:
Sinkholes are empty spaces in the ground that occur due to the landslide of large volumes of land, creating craters of different sizes. This landslide takes with it everything that is on top of it, such as houses, animals, streets and even entire buildings. While these holes can occur due to engineering flaws, the most common reason is the excessive use of groundwater, which creates an empty space in the interior of the soil and causes the earth to sag.
Which statement about identical twins is TRUE?
A. They have identical DNA in all of their cells.
B. They are not genetically identical to each other.
Answer:
A. They have identical DNA in all of their cells.
Explanation:
Identical twins are also known as monozygotic twins. They result from the fertilization of a single egg that splits in two. Identical twins share all of their genes and are always of the same sex. In contrast, fraternal, or dizygotic, twins result from the fertilization of two separate eggs during the same pregnancy.
Answer:
A. They have identical DNA in all of their cells.
Explanation:
All of the cells in your body share the same DNA as was found in that first cell.

What would happen if DNA and RNA did not operate according to principles of
directionality?
Answer:
RNA and DNA wouldn't be read in the proper order and would code for different proteins, with devastating consequences.
Explanation:
Directionality is important in DNA and RNA because it ensures that all transcription and translation occurs in an organized and uniform manner. Without directionality, the DNA and RNA machinery would get confused and read the nucleotides into the machinery backward, which would give the sequence an entirely different meaning.

Just by looking at the guinea pig, you would be able to tell if its genotype were HH or Hh.
A. True
B. False
Answer:
it depends on where your going to be looking if you look at the genitals then A true but, if your looking at just the body and head B
Answer:
B. False
Explanation:
HH and Hh have the same phenotype, so you could not determine the genotype of the guinea pig just by looking at it.
Cells created by meiosis can be
represented by which of the following?
A.2B
B.B
C.2N
D.N
Answer:
D. N
Explanation:
Meiosis is a kind of cell division which produces daughter cells that are genetically different from the parent cell and have a reduced number of chromosomes (by half).
Meiosis occurs only in reproductive cells to produce gametes. If a diploid (2n) cell undergoes meiosis, a haploid (n) daughter cell will result. This means that the chromosome number has been reduced by half in order to maintain the chromosomal number of the next generation.
Study the diagram of gametogenesis where egg cells and sperm cells
undergo meiosis I and meiosis II. Note the number assigned to each cell.
Identify the number of chromosomes in the different cells, represented
by a circle, by writing the symbol N for haploid and 2N for the diploid.
Write your answers on a separate sheet of paper.
A diploid cell undergoes meiosis to produce one egg and 3 polar bodies with 23 chromosomes each.
What happen during the egg formation?During egg formation in the ovary, Primary oocyte (diploid) having 46 chromosomes undergoes meiosis I to form one secondary oocyte and one first polar body.
Both the secondary oocyte and one polar body are haploid having 23 chromosomes. Both daughter cells then undergo meiosis II, the first polar body divides to give two polar bodies and the secondary oocyte divides by meiosis II to form one ovum.
Therefore, during egg formation in the reproductive system, a diploid cell (a primary oocyte) undergoes meiosis to produce one egg and 3 polar bodies with 23 chromosomes each.

Explanation:
El pelaje negro de los borregos se debe a un alelo recesivo n frente a su alelo N que determina el pelaje blanco. Si cruzamos un individuo homocigótico blanco con un homocigótico negro, ¿de qué color serán los descendientes de la primera generación filial? GENOTIPO-FENOTIPO
Answer: Los descendientes de la primera generación filial tendrán un genotipo Aa y un fenotipo color blanco.
Explanation:
Un gen es un segmento de ADN que codifica para una proteína. Para cada gen, hay distintas versiones, conocidos como alelos. Por ejemplo, el gen que codifica para el pelaje tiene los alelos para el color blanco y para el color negro. Considerando que los organismos diploides tienen dos copias de cada gen (dos alelos), un alelo dominante solo necesita una copia para expresarse. Mientras que un alelo recesivo, necesita dos copias.
En este ejemplo, el borrego homocigota blanco tiene un genotipo (conjunto de genes) de AA ya que el color blanco es dominante y al ser homocigota indica que ambos alelos son iguales. El borrego homocigota negro tiene un genotipo de aa ya que se necesitan dos alelos recesivos para mostrar ese fenotipo (características visibles).
Los borregos producen gametos, los cuales son células sexuales (espermatozoide u óvulo) haploides, es decir que solo poseen un alelo de cada gen. Entonces el borrego AA solo produce gametos con genotipo A, mientras que el borrego aa solo produce gametos con genotipo a. Estos gametos son los que se cruzan, es decir que la descendencia solo puede tener un genotipo Aa (con un alelo de cada padre)
El genotipo Aa posee un alelo dominante A (que codifica para el color blanco) que enmascara los efectos de el alelo recesivo a (que codificaría para el color negro) Entonces, los descendientes de la primera generación filial tendrán un genotipo Aa y un fenotipo color blanco.

how does natural selection impact the way a population adapts?
Answer:
The organisms with the more desirable traits will survive and pass on their genes.
Explanation:
"Natural selection" is pretty much "survival of the fittest." This means that the organisms who have a better chance of surviving and reproducing will control the way a species adapts. For example, there may be a mutation in a species of moths that make their wings more brown instead of yellow (just threw a random color out there). Well, the moths born with the mutation that turns their wings brown will likely live longer and be able to reproduce more because they can blend in with their environment better. So, as a result, their mutation can get passed on and the species will adapt to have more moths with brown wings.
