You are taking a cruise from California to Hawaii. About halfway there the ship begins to sink. You are able to board a lifeboat, but now you are floating in the ocean waiting to be rescued. After several days you are so thirsty that you bend over the side of the boat and drink lots of salty seawater. What happens to your body
Answer:
What happens is the dehydration phenomenon.
Explanation:
The phenomenon of dehydration occurs because when you are at sea for many days, you breathe the salty mist that occurs on the surface of the sea (which is even greater at night), this mist is high in solutes and salts that is why that when inhaled, the body will seek to increase blood volume to lower the plasma concentrations of these solutes in the blood.
Also, during breathing, a lot of water is lost and other physiological processes are why we need a daily consumption of water.
In the case of this situation where the person is abandoned, water consumption is low.
The consequences of dehydration are serious, since there is hypotension, decreased blood volume, hypovolemic shock, loss of consciousness and even possible death.

The amount of energy at trophic levels one and four in an ecosystem is indicated by the numbers.
Only 10% of the energy is passed on to the next trophic level.
What is the total amount of energy in levels two and three?
Answer:
1100
Explanation:
There is 10% of total energy in each increasing trophic level. 10,000 / 10 = 1,000 ,so there are 1,000 units of energy in trophic level 2.
1,000 / 10 = 100, so there are 100 units of energy in trophic level 3.
1,000 + 100 units of combined energy would be 1,100 units of energy.

Three friends were arguing. Richa said: "Plants do photosynthesis during the day time and respiration during night". Soniya said: "Plants take in oxygen and release carbon dioxide during night but they release oxygen and take in carbon dioxide during day time". Aarush said: "Plants take in carbon dioxide and release oxygen during both day and night". Whose statement is correct among the three friends? Justify.
Answer:
The third friend is correct.
Explanation:
Plants use photosythesis whenever there is a powerful enough light source to do so. They use the ATP from photosythesis to drive cellular respiration, which is how they get large amount of ATP, photosythesis just get the correct materials needed to do so. And while phototsytheis does slow down significantly at night, some plants(like in the desert), do use it at night simply because those conditions are easier for the plant to use photosytheis. Keep in mind that photosythesis uses Carbon dioxide and releases oxygen, and in the calvin cycle, carbon is still used, and oxygen is used to a very minor extent.

Save and Exit
The cell cycle is the process of the formation of new cells in organisms. It is an important process in burn victims as they reproduce new cells. Thus, option D is correct.
What is the cell cycle?The cell cycle is the chain of steps that occurs in an organism that includes the division of the parent cell into the daughter cells through various phases.
The cell cycle includes the G1, S, G2, and mitosis phases. The cell increases in its size in gap 1, and copies the DNA material in the synthesis phase. In the gap 2 phase, the cell undergoes preparatory changes.
The actual division occurs in the mitosis phase where the cell reproduces and increases in number to replace the old and dead cells of the burn victim. It promotes the growth and repair of the injured area.
Therefore, option D. the cell cycle reproduces new cells in burn victims.

Just considering one locus (a specific location on a DNA strand), evidence at a crime scene shows a genotype of 5, 9 STR repeats at this locus. The general population frequencies for the alleles 5 and 9 are 0.100 and 0.300, respectively. How frequent would the genotype 5, 9 be expected to be in the general population
Answer:
0.1 x 0.3 = 0.03 = 3%
Explanation:
Assuming a process of random mating in the population, it is possible to infer that the genotype frequencies will be the product of the allele frequencies. The random mating is one of the postulates of the Hardy-Weinberg Law, which is widely used in population genetics to estimate genotypic frequencies when populations are expected to be in an equilibrium state (it is also expected by default in human populations). In this case, the genotype frequencies will be certainly low (3%), thereby this locus may be useful to investigate a police case.

A body decelerates uniformly to a constant speed and after some time it accelerates uniformly Draw the shape of speed time graph for such a motion . Label the three sections of this graph. What is the quantity which is measured by the area occupied under speed time graph ?
Answer:
Kindly check attached picture
Quantity measured is DISTANCE
Explanation:
Segment AB = measures uniform deceleration
BC = Constant speed moved by the car
CD = Uniform acceleration
During uniform deceleration: the speed of the body is reduced at a constant rate with time.
During Constant Speed, the car maintains a Velocity which does not increase or reduce at a certain time interval.
During uniform acceleration the speed of the car increases at a constant rate with time.
B) THE quantity measured by the area covered under a speed-time graph is distance :
With speed on the vertical (y-axis) and time on the horizontal (x-axis)
Area of trapezium = 0.5(AD + BC) × height
Both plants and animals respond to environmental stimuli. Identify the correct statement(s) about this response. Select all that apply. Select all that apply. Both plants and animals have physiological cycles called circadian rhythms. The molecular processes determining how plants and animals perceive environmental changes are equally complex. The molecular processes determining how plants and animals perceive environmental changes are often homologous.
Answer:
All three options are correct;
1. Both plants and animals have physiological cycles called circadian rhythms.
2. The molecular processes determining how plants and animals perceive environmental changes are equally complex.
3. The molecular processes determining how plants and animals perceive environmental changes are often homologous.
Explanation:
Stimulus in biology can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). All living organisms (both plants and animals) respond to changes in their environment and as such an appropriate reaction or response is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.
In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ.
Since both plants and animals respond to environmental stimuli, it simply means that;
1. Both plants and animals have physiological cycles called circadian rhythms. This is a natural internal process that controls the physical, mental, and behavioral changes in living organisms such as the sleep-wake cycle. The circadian rhythm is simply the internal body "24 hour" clock.
2. The molecular processes determining how plants and animals perceive environmental changes are equally complex.
3. The molecular processes determining how plants and animals perceive environmental changes are often homologous. This simply means that, specific sense organs or sensory receptors would only respond to the stimulus they are primarily created to respond to. For example, the eyes can only be used to see and not smell, ear or taste.

Energy is released from ATP when every phosphate bond is broken. the last phosphate bond is broken. all three phosphate bonds are formed. the last phosphate bond is formed.
Answer:
the last phosphate bond is broken
Explanation:
Adenosine triphosphate, commonly known as ATP, is a high energy storage molecule. It is the form of energy usable by living cells to carry out their various life functions. ATP is synthesized in living systems during the process of cellular respiration.
ATP is a chemical compound that contains an Adenine base, ribose sugar, collectively called Adenosine, and three phosphate groups. Hence, the name Adenosine triphosphate. The stored energy in ATP is released when the bond holding the last phosphate group is broken. This releases a phosphate group and Adenosine diphosphate (ADP) molecule.

What specialized tissues do vascular plants have that other plants do not? A. Structures for standing straight up B. Organs for absorbing sunlight C. Tissues for moving water around D. Flowers for reproduction
The answer is C.The name vascular implies that the plant can transport sieve through tube-like structures(phloem and xylem).
Option C. Tissues for moving water around are vascular plants have that other plants do not
Vascular plantsVascular plants exist also known as tracheophytes. They contain pteridophytes, gymnosperms, and angiosperms. Non-vascular plants lack a specialized vascular system for transporting water and nutrients. They may include simple structures that may specialize to perform transportation, e.g. algae and bryophytes.Vascular plants contain vascular tissues which distribute resources through the plant. Two types of vascular tissue occur in plants: xylem and phloem. Phloem and xylem exist closely associated with one another and are typically located immediately adjacent to each other in the plant.xylem, plant vascular tissue that represents water and dissolved minerals from the roots to the rest of the plant and also furnishes physical support. Xylem tissue consists of a combination of specialized, water-conducting cells known as tracheary elements.
Hence Option C. Tissues for moving water around are vascular plants have that other plants do not.
