Stimulus refers to events that produce a response in the body due to changes in the environment , therefore response to stimulus is essential for an organism to survive and adapt in its environment.
What is a stimuli?A stimuli is any sensation or action that produces a response in a tissue or organ.
Stimulus is the plural noun of stimuli.
There are two types of stimulus:
external stimulus which comes from outside the body internal stimulus which comes from within the body.The body responds to stimulus in order to adapt to changes in both its external and internal environment.
For example, when the envrionment is hot, the brain receives stimulus from heat receptors and then we start to sweat in order to cool down.
Stimulus are received by sense organs in the body
There are five sense organs in the body;
eye - for sightear - for hearing nose - for smellingskin - for feeling mouth - for tastingSensory receptors in sense organs receives stimulus and send it to the brain through the sensory neurons.
The brain processes the stimulus and send messages back through motors neurons to appropriate organs and tissues to act in response to the stimulus.
Therefore, response to stimulus is essential for an organism to survive and adapt in its environment.

1. A student predicted the reaction between hydrogen and oxygen gas would yield 125 mL of water. However, after measuring the water formed in the reaction, the student determined that only 110 mL of water was actually formed. Determine the percent yield for this reaction.
A. 75%
B. 88%
C. 100%
D. 113%
HINT: 96 yield= (actual yield/ expected yield ) X 100%
Answer:
B. 88%
Explanation:
percent yield is the actual yield divided by the theoretical (predicted) yield, then multiplied by 100 to get a percentage.
110/125 = 0.88
0.88 x 100 = 88%
In chemistry, the term yield also known as the reaction yield represents the measure of the quantity of the moles of a product formed in the reaction to the reactant used. The correct option is B.
What is percent yield?The amount of the product actually made compared with the maximum calculated yield is defined as the percent yield. It can also be known as the ratio of the actual yield to the theoretical yield.
The ideal quantity of the product is called the theoretical yield and it is obtained by working a stoichiometry problem. The actual amount of the product formed gives us the actual yield.
The equation of the percent yield is given as:
%yield = Actual yield / Theoretical yield × 100
110 / 125 × 100 = 0.88 × 100 = 88%
Therefore the percent yield of the reaction is 88%.
Thus the correct option is B.

QUESTION
A bee buzzes inside a flower to drink some nectar. While there it touches the stamen. Later the bee goes to another flower and comes into contact with the flower's pistil. Which process of reproduction is this helping with?
ANSWER
The bee is helping in pollination which is an important event in case of sexual reproduction in flowering plants.
Pollination is a part of pre-fertilisation ( gamete transfer ).
Pollination by insects ( most commonly bees ) is known as Entamophily

A tank containing 5.00 L of nitrogen at 75.0 atm pressure and 28.0 C is left standing in sunlight. Its temperature rises to 50.0C. What is the pressure at this higher temperature?
Answer:
80.5 atm
Explanation:
First of all, we convert 28.0 °C and 50.0 °C into K:
28.0 + 273.16 = 301.16 K50.0 + 273.16 = 323.16 KTo answer this problem we'll use Gay-Lussac's Law, which states that:
T₁*P₂=T₂*P₁In this case:
T₁ = 301.16 KP₂ = ?T₂ = 323.16 KP₁ = 75.0 atmWe put the data:
301.16 K * P₂ = 323.16 K * 75.0 atmAnd solve for P₂:
P₂ = 80.5 atmThus, the correct answer is 80.5 atm.

How many valence electrons are there in Se atom?
Answer:
4 valence electrons
Despite the fact that the word silicon has a ubiquitous affiliation with all things electronic, Si itself is not a good electrical conductor. It has 4 valence electrons, meaning that filling its outer shell it can form a very strong lattice with 4 neighboring Si atoms-with no un-bonded electrons remaining
Answer:
The numer of valence electrons is defined as the number of electrons present in the outer most shell of the atom.So, in the case if selenium, there are 6.
Which is a general property of cell membranes? a) Membranes contain more lipid than protein. b) Membrane proteins have a polar head and a non-polar tail. c) Membrane lipids are amphipathic. d) Membranes contain covalent bonds between fatty acids
Answer:
c) Membrane lipids are amphipathic.
Explanation:
A cell can be defined as the structural, fundamental, biological and functional unit of life. Cells are found in all living organisms because they are the basic unit of life.
In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles. Some examples of cell organelles found in all living organisms such as trees, birds, and bacteria include; nucleus, mitochondria, lysosomes, ribosomes, chromosomes, endoplasmic reticulum, cytoskeleton, vesicles, golgi apparatus, and cell membrane.
Cell membrane is the wall of a cell and typically controls what leaves and enters the cell.
A general property of cell membranes is that membrane lipids are amphipathic. All the lipid molecules found in the cell membrane are amphipathic or amphiphilic, which means that they are "water loving" (hydrophilic) with a polar end or "water fearing" (hydrophobic) with non-polar end. Thus, membrane lipids have an end that's soluble in water (polar) while the other end is soluble in fat (non-polar).
The membrane lipids are amphipathic.
• In the majority of cell membranes in animals, lipids, that is, fatty molecules forms about 50 percent of the mass of the cell.
• All the molecules of lipid in a cell membrane are amphipathic, that is, they possess a polar end or hydrophilic and non-polar end or hydrophobic end.
• The phospholipids are the most abundant lipids found in the cell membrane.
• They have a polar head group and two hydrophobic hydrocarbon tails.
• It is the amphipathic nature and shape of the molecules of lipids, which makes them to produce bilayers spontaneously.
Thus, correct answer is option c, that is, membrane lipids are amphipathic.
