Explanation:

Hope this helps
A thunderstorm adds freshwater to the ocean as it lowers the density of the water. Thus, option B is correct.
What creates density variations in ocean water?
Differences in temperature and salinity that create density variations in ocean water and salinity refer to how much salt that the ocean water contain, and the temperature became a very important factor because it could determine the amount of water that evaporates.
The term thermohaline circulation is the mixing of hot and cold water from upper surface to the lower surface. This is caused by the temperature and salinity that changes in the water.
It is driven by the density gradient in which the thermohaline circulation begins when the temperature is very cold and ice forms in the sea. The surrounding sea water gets saltier and its density increases and it sinks down.
Therefore, A thunderstorm adds freshwater to the ocean as it lowers the density of the water. Thus, option B is correct.

Which crop leaves soil with the lowest levels of nitrogen?
Answer:
cotton
Explanation:
Cotton crop leaves soil with the lowest levels of nitrogen.
What is a nitrogen?Nitrogen is the chemical element with the symbol N and atomic number 7. Nitrogen is a nonmetal and the lightest member of group 15 of the periodic table, often called the pnictogens. It is a common element in the universe, estimated at seventh in total abundance in the Milky Way and the Solar System.
Nitrogen is important to the chemical industry. It is used to make fertilizers, nitric acid, nylon, dyes and explosives. To make these products, nitrogen must first be reacted with hydrogen to produce ammonia. This is done by the Haber process.
Nitrogen is important to all living things, including us. It plays a key role in plant growth: too little nitrogen and plants cannot thrive, leading to low crop yields; but too much nitrogen can be toxic to plants [1]. Nitrogen is necessary for our food supply, but excess nitrogen can harm the environment.

Start at the top and move clockwise around the symbol. •CT: Nice work! You have created the electron dot formula for chlorine. Intro ) Final
Answer:

2. 7 valence electrons
3. u did it right
Good job
The chemical symbol for chlorine is Cl. There are seven valence electrons present in chlorine.
What are valence electrons?
Valence electrons are electrons in an atom's outermost shell, or energy level. For example, oxygen contains six valence electrons, two of which are in the 2s subshell and four of which are in the 2p subshell.
The chemical symbol of the element (as found on the periodic table) is written in the Lewis symbol for an atom, and the valence electrons are depicted as dots encircling it.
The number of electrons in an atom's outermost shell is referred to as its valence electrons. The final shell of the chlorine atom now has 7 electrons. As a result, a chlorine atom contains 7 valence electrons.
Therefore, Cl is the chemical symbol for chlorine. In chlorine, there are seven valence electrons.

write a letter to the government explaining the dangers posed by global warming/climate change
Answer:
Global climate change has already had observable effects on the environment. Glaciers have shrunk, ice on rivers and lakes is breaking up earlier, plant and animal ranges have shifted and trees are flowering sooner. Effects that scientists had predicted in the past would result from global climate change are now occurring: loss of sea ice, accelerated sea level rise and longer, more intense heat waves. Scientists have high confidence that global temperatures will continue to rise for decades to come, largely due to greenhouse gases produced by human activities. The Intergovernmental Panel on Climate Change (IPCC), which includes more than 1,300 scientists from the United States and other countries, forecasts a temperature rise of 2.5 to 10 degrees Fahrenheit over the next century.

Color in poison dart frogs is controlled by a single gene with multiple alleles. A blue poison dart frog that is heterozygous for the blue allele (Cb) and red allele (Cr) is crossed to a yellow poison dart frog that is heterozygous for the orange (Co) and yellow (Cy) alleles. Their progeny are 1/2 blue, 1/4 orange, and 1/4 yellow. Determine the order of dominance for the alleles. (Order of dominance is indicated as: A > B > C > D such that A is dominant over all alleles, B is dominant over C and D, C is dominant only to D, and D is recessive to all alleles.)
Answer:
Cb>Cy>Co>Cr
Explanation:
First of al we need to do the Punnett square. As a result we get the genotypes:
CyCb
CyCr
CoCb
CoCr
Because there are no red frogs, red is the least dominant as it isn't expressed in any genotype.
Half of the progeny are blue and half of the possible genotypes contain the blue allele meaning that blue is expressed in all genotypes. This means that blue is the most dominant.
The only alleles left are yellow and orange. We can deduce that yellow is more dominant than orange because one of the parent frogs is yellow and contains the genes for yellow and orange.
As a result blue is the most dominant, yellow is the second most dominant, orange is the third most dominant and red is the least dominant.

Answer:
D. Population genetics
Population genetics is the study of genetic variation within populations, and involves the examination and modelling of changes in the frequencies of genes and alleles in populations over space and time. ... In natural populations, however, the genetic composition of a population's gene pool may change over time.
Explanation:
microevolution - evolutionary change within a species or small group of organisms, especially over a short period. (Not studying the overall evolution in the population, just a single allele usually) Not it then
macroevolution - Macroevolution in the modern sense is evolution that is guided by selection among interspecific variation, as opposed to selection among intraspecific variation in microevolution (this goes over huge groups of different species) Not it then
gene pool - The gene pool is the set of all genes, or genetic information, in any population, usually of a particular species. (Not the study of evolution in a population) Not that then

What was the average of diameters (cm) for the Willapa Bay urchins sampled before the hunt? (Type just the number rounded to the tenth place and do not include units.)
Answer:
See Explanation
Explanation:
The question is incomplete as the diameters of the Willapa Bay urchins were not given.
However, I'll give a general way to solve this problem.
Average is calculated using:
[tex]Average = \frac{\sum x}{n}[/tex]
i.e. Sum of all diameters divided by the number of bay urchins.
The diameter of urchins is usually between 6cm to 12cm; So, I will assume the following diameters for 10 urchins.
10cm, 8cm, 10cm, 7cm, 9cm, 10cm, 6cm, 10cm,8cm, 8cm
Using the above data, the average is:
[tex]Average= \frac{10+8+10+7+9+10+6+10+8+8}{10}[/tex]
[tex]Average= \frac{86}{10}[/tex]
[tex]Average= 8.6[/tex]
