Answer:
I think it is colon because the other ones did not make sense
Hope you have a good day
1. Depth: The water level in the Great Salt Lake fluctuates from year to year. Water levels drop and salinity increases when less water flows into the lake than usual. Not only that, but the wetlands dry up and the shoreline recedes. The reason the shoreline shifts so dramatically is because it sits at the bottom of a broad and relatively flat basin. For a visual example, think of pouring water into a plate versus a bowl.
Salinity: This Great Salt Lake has a high mineral content, as most terminal lakes are, which means that it is quite salty. Even the fresh water flowing into the lake contains small amounts of dissolved minerals. As water evaporates from the lake, the minerals stay behind. As a result, these minerals have accumulated to very high levels because they have been left behind for thousands of years. The Great Salt Lake is between 3.5 and 8 times saltier than the ocean. However, the organisms that survive in such saline conditions have adapted to their surroundings through special features.
Temperature: The Great Salt Lake has a very shallow depth, with an average of 14 feet deep and a mere maximum of 33 feet. This means that a lot of the surface area is exposed to the air, and is at the mercy of its seasonal temperature fluctuations. In the summer, rise to more than 80 degrees Fahrenheit while falling to below freezing in the winter.
2. Depth: Salinity drops and lake levels rise during high precipitation years. Wetlands get covered by salt water, and the shoreline expands, sometimes destroying wildlife habitats and killing sensitive vegetation.
Salinity: <span>Changes in lake elevation are accompanied by changes in salinity. The salinity in the lake decreases as incoming fresh water dilutes the salt water. This happens during the wet years. During dry years, however, salinity increases as continued evaporation removes fresh water.
</span>Temperature: Because of the lake's salt high content, the water doesn't usually freeze. However, as the temperature drops during the winter, less saline zones freeze solid, and most of the lake turns into a vivid pea-soup green color. In mid-March, temperatures begin to rise again as brine shrimp begin hatching. By late April, juvenile, and adult brine shrimp fill the water, serving as food for migrating and breeding birds.
3. Brine shrimp are smaller in highly salty water and larger in less salty water. Also, salinity levels also affect the rate of sexual development. Higher salinities produce adults who reach maturity quicker but are shorter in length. As salinity increases, the abdomen becomes longer relative to body length. Low salinity may also cause cysts to crack prematurely, as well as allowing other competitors into the ecosystem. High salinity results in offspring that develop quickly but are smaller and have a relatively longer abdomen. In short, effects of abiotic conditions on brine shrimp are development rate, the rate of sexual maturity, the overall length of the abdomen, amount/type of food available, cyst density and location.
4. One limiting factor of brine shrimp are predators: corixids that consume brine shrimp, grebes that consume brine shrimp and their cysts, and humans that commercially harvest brine shrimp cysts. Another limiting factor for brine shrimp is cooler temperatures. They<span> are much more productive in warmer water and consume more phytoplankton. However, when the lake water temperature is cold, the shrimp population tends to decline. </span>
Answer:
Explanation:
A) to determine amino acid sequence of the protein produced by that gene. We will use cDNA library, we will hybridize given part of DNA sequence ( as this part only contains exon part). Than we will isolate the hybridize part and translate this sequence using generic coding table.
B) for determine presence or absence of introns in gene used isolated cDNA in first question. Now we will add this cDNA to DNA library. Here cDNA due to complementary mature binds with DNA. If cDNA binds completely with gene with out looping part of gene it shows that gene is having only exons .
And if along with hybridization part some looped part present in between-- it shows both exons and intron are present.
C) for determining alternative splicing we will use cDNA library.
d) to determine length of mature mRNA which includes both the UTR and poly A sequence we will go for cDNA cloning and look for particular cDNA complementary to DNA segments. And later we isolate that cDNA and examine its whole length
E) to determine which cells in the tribble body express this particular mRNA . We use fluorescent tagged small DNA part provided. Then we will add this DNA probe to supplied tribes. The cells which are expressing , will have cDNA will bind to probe and florescent can be detected. Cells which are not expressing that gene, here probe will not bind and no fluorescence.
F) to determine that whose blood strain is this. We will do VBTR profiling . Which VNTR profiling similar to belief stain help to determine which blood stain is this.
Answer:
The major levels of organization in the body, from the simplest to the most complex are: atoms, molecules, organelles, cells, tissues, organs, organ systems, and the human organism.
All living and non-living things are made of one or more unique substances called elements, the smallest unit of which is the atom, (for example, the element oxygen (O) is made of O atoms, carbon (C) is made of C atoms and hydrogen (H) is made of H atoms. Atoms combine to form molecules.
All living structures are made of cells, which are made of many different molecules. Cells are the smallest independent living thing in the human body. The body is made of many different cell types, each with a particular function, (for example muscle cells contract to move something, and red blood cells carry oxygen). All human cells are made of a cell membrane (thin outer layer) that encloses a jelly-like cellular fluid containing tiny organ-like structures called organelles.
A tissue is a group of similar cells that work together to perform a specific function. There are four main tissue types in humans (muscular, epithelial, nervous and connective). An organ is an identifiable structure of the body composed of two or more tissues types (for example, the stomach contains muscular tissue made of muscle cells, which allows it to change its shape, epithelial tissue which lines both the inner and outer surface of the
stomach, nervous tissue which sends and receives signals to and from the stomach and the central nervous system, and connective tissue which binds everything together).
Organs often perform a specific physiological function (for example, the stomach helps digest food). An organ system is a group of organs that work together to perform a specific function (for example, the stomach, small and large intestines are all organs of the digestive system, that work together to digest foodstuff, move nutrients into the blood and get rid of waste). The most complex level of organization, the human organism is composed of many organ systems that work together to perform the functions of an independent individual.
hope this answer helps you.....
