#TheWizzer
Answer:
Proteins in your blood called clotting factors signal each other to cause a rapid chain reaction. It ends with a dissolved substance in your blood turning into long strands of fibrin. These get tangled up with the platelets in the plug to create a net that traps even more platelets and cells.

Which of the following is true about adaptation?
I. It is random.
II. It results from genetic mutations.
III. It only affects an individual in a population.
I, II, and III
I and II
II and III
I only
Answer: I and II
Explanation: so basically, when adaptation occurs, it usually happens over a long period of time due to climate, predators, etc. because of these adversities, Genetic mutations occur, helping that animal and its species as a whole survive, which checks number 2. number one is also correct because adaptation can not be predicted. it happens randomly at some point in time. 3 is incorrect because multiple offspring in a species could have adaptations that provide more of an advantage.

Which region of the nephron is labeled in blue in the image?
Proximal convoluted tubule
Loop of Henley
None of the above
Proximal convoluted tubule is the part labeled from the above diagram of nephron.
What is nephron?The nephron is the small microscopic structural and functional unit of the kidney. It comprises of a renal corpuscle and a renal tubule. The renal corpuscle is composed of a tuft of capillaries which is refer to as the glomerulus and Bowman's capsule. The renal tubule extends from the capsule.
Therefore, The proximal convoluted tubule is a portion of kidney nephron between the loop of Henle and the collecting tubule.

Question 1 options:
Mitosis occurs in germ cells and meiosis occurs in somatic cells.
Meiosis produces four 2N daughter cells; mitosis produces two 2N daughter cells.
Crossing over takes place in mitosis and not in meiotic cell division.
The number of chromosomes remains the same in mitosis and is reduced by half in meiosis.
Answer:
Crossing over takes place in mitosis and not in meiotic cell division.
Explanation:
Mitosis occurs in somatic cells and meiosis occurs in germ cells. The crossing over event takes place in meiotic cell division and not in mitosis. Meiosis produces four n daughter cells.
1. What is the significance of the specific gravity of the abnormal urine?
Answer:
A very high specific gravity means very concentrated urine, which may be caused by not drinking enough fluid, loss of too much fluid (excessive vomiting, sweating, or diarrhea), or substances (such as sugar or protein) in the urine.
Explanation:
Urine specific gravity is a significant and convenient way to measure the abnormal urine. It indicates dehydration or presence of substances in the urine as in case of diabetes.
What is Specific gravity?
Urine specific gravity (USG) measures the concentration of particles which are present in the urine and the density of urine compared with the density of water. Measurement of USG is an easy way and very convenient way to know a patient's hydration status as well as the functional ability of kidneys.
Urine specific gravity falls between the range of 1.002 and 1.030 if the kidneys are functioning normally. However, if specific gravity results above 1.010 this can indicate mild dehydration in that person. The higher the number of specific gravity, the more dehydrated a person may be.
A very high specific gravity means very concentrated urine, which may be due to not drinking enough fluid, loss of too much fluid, or substances such as sugar or protein in the urine.

explaining how carbon is
transferred within and
between organisms and the
environment.
Answer:
For example, in the food chain, plants move carbon from the atmosphere into the biosphere through photosynthesis. They use energy from the sun to chemically combine carbon dioxide with hydrogen and oxygen from water to create sugar molecules.
Describe: Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants get rid of carbon dioxide gas through a process called respiration. Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement. Organisms play an important role in the carbon cycle in the following ways: Plants absorb carbon from the environment in photosynthesis and return it in respiration. Animals obtain their carbon by eating plants; they release carbon in respiration.

Which statement describes the difference between ectothermic and endothermic animals?
Question 5 options:
Ectothermic animals live in cold climates, and endothermic animals live in warmer places.
Ectothermic animals live in the water, and endothermic animals live on the land.
Ectothermic animals have a lower body temperature than endothermic animals.
Ectothermic animals have a body temperature that is the same as their environment, and endothermic animals have a constant body temperature.
Answer:
Statement D
Explanation:
Ectothermic means cold-blooded, which means they can not generate there own heat or maintain a constant body temp.
But us as humans are Endothermic because we remain at a constant body temp, also known as warm-blooded.

We can confirm that on the islands, Charles Darwin observed species similar to mainland South American species and to those found on the other islands.
What did Darwin notice about these species?Darwin noticed that each of these species were very similar, but possessed slightly different traits. These traits seem to perfectly fit the needs of each species for their specific island, leading to his creating the theory of evolution through natural selection.
Therefore, we can confirm that on the islands, Charles Darwin observed species similar to mainland South American species and to those found on the other islands.

Analyze the graph and identify some factors that may contribute to the rotifer population leveling off in the absence of water fleas. Explain your answer in 1–2 sentences.
Answer:
(Leveling off = it stays the same even though it had a increasing period) When looking at the end of the graph you can see that it came back to what it was, which means the rotifers are not increasing anymore. That's because of the carrying capacity (a species' average population size in a particular habitat), and the carrying capacity in this situation is the flask. Therefore the flask has limited space.
