why are lipids important for survival of animals
Answer:
Lipids play an important role in storing energy. If an animal eats an excessive amount of energy it is able to store the energy for later use in fat molecules. Fat molecules can store a very high amount of energy for their size which is important for animals because of our mobile lifestyles.

The structure of a human skin cell differs from that of a human muscle cell. The two cells most likely have different __________. Choose the correct answer.
Answer:
The correct answer would be - functions.
Explanation:
The structure of the skin cells and muscle cells are different and have a different number of cell organelles on their role in the body. Skin cells are a special type of cells that keep on shedding and replaced by new ones therefore they need less energy and have many mitochondria.
In contrast, muscle cells have different structures as they need a high amount of energy to make movements and therefore have lots of mitochondria in the cell.

If a rose plant has a genotype of Ffgg, what are the possible genetic combinations of offsprings that could be
present from this plant?
Answer:
Suppose you have a parent plant with purple flowers and a parent plant with white flowers. Because the b allele is recessive, you know that the white-flowered parent must have the genotype bb. The purple-flowered parent, on the other hand, could have either the BB or the Bb genotype. The Punnett square in Figure below shows this cross.

Body systems in the human body work together to support the essential life functions of the body. The urinary system is under influence of several other body systems to help it function properly. Which of these CORRECTLY pairs a body system and its influence on the urinary system?
Question 31 options:
The nervous system releases the hormones, ADH and aldosterone, which adjust the rates of fluid and electrolyte reabsorption in the kidneys.
The nervous system monitors distention of the bladder, controlling urination.
The cardiovascular system makes erythropoietin to make new red blood cells.
The digestive system excretes wastes not filtered by the kidneys.
Answer:
The urinary system works with the digestive system and in other systems in your body. It releases the waste from the food they digest and it also works with the circulatory system. It works in other systems in the body to help the body maintain the homeostasis says the Biologists. The waste product is kept dissolved in the liquid (water) and in mammals is stored in a bladder. The work of the kidney inside the body is to maintain acid and water-salt levels of the blood. It releases the waste in the body and it also filters the blood inside of you.
Explanation:
I dont know if this helps but its what I have gotten told. I know its not the exact answer but when i looked up your question its what i got.
Answer:
The nervous system monitors distention of the bladder, controlling urination.
Explanation:
The endocrine system releases the hormones, ADH and aldosterone, which adjust the rates of fluid and electrolyte reabsorption in the kidneys. The kidneys make erythropoietin to make new red blood cells for the cardiovascular system. The digestive system absorbs water needed by the kidneys to excrete wastes.

Calculate the efficiency of a hair dryer which takes in 3000J of energy per second and transfers 600J as useful heat energy. Calculate the efficiency of the hair dryer.
Answer:
The efficiency of the hair dryer is 0.2 or 20%
Explanation:
The efficiency of a machine or any appliance is a measure of the useful work done by the machine when an effort is applied to the machine. The higher the efficiency of a machine, the more useful work the machine does.
Due to the economical and environmental impact of energy production, machines and appliances of high efficiency are being developed and recommended for domestic as well as industrial use nowadays.
In electrical appliances, energy is usually supplied by electrical power units. The higher the efficiency of an electrical appliance, the less power it consumes to do useful work. For a hair dryer which takes in 3000 J of energy per second and transfers 600 J of useful heat energy, its efficiency is calculated with formula below:
efficiency = useful energy / total energy input
Efficiency = 600 J / 3000 J = 0.2
Therefore, the efficiency of the hair dryer is 0.2 or 20%

The compound can provide the energy for chemosynthesis is light photon and carbon dioxide. Thus, option C is correct.
What is photon?
The energy stored in bundles or the packets has been known as the photon. Chemosynthesis has been referred to the process by which some organism obtain food from inorganic chemicals rather than from light. There are many chemosynthetic bacteria that obtain food by the metabolism of methane, hydrogen sulfide or carbon dioxide.
Light photons are not required for chemosynthesis. It is only necessary during photosynthesis. Chemosythesis has been involves the inorganic chemicals therefore, light photons are not required during chemosynthesis.
The organism which provides evidence that matter and energy can be cycled through an ecosystem without sunlight is a lanternfish on the Atlantic Ocean floor and the technique which will prove most effective to eliminate the greatest number of organisms is to remove methane and hydrogen sulfide.
Therefore, The compound can provide the energy for chemosynthesis is light photon and carbon dioxide. Thus, option C is correct.

features of xerophytes
Answer:
Xerophyte survival characteristics:
Thick cuticle.
Stomatal closure.
Reduction in # of stomata.
Stomata hidden in crypts or depressions in leaf surface (less exposure to wind and sun).
Reduction in size of transpiration surface (lower leaf only).
Increased water storage.
Explanation:
Xerophyte adaptations increase water intake, limit water loss, and store water efficiently. Water intake adaptations include deep or widespread roots, and high salt content to increase osmosis. Xerophytes have thick cuticles, lost or finely divided leaves, reduced stomata, and CAM photosynthesis
