Answer:
Surface tension in water owes to the fact that water molecules attract one another, as each molecule forms a bond with the ones in its vicinity. At the surface, though, the outmost layer of molecules, has fewer molecules to cling to, therefore compensates by establishing stronger bonds with its neighbors, this leading to the formation of the surface tension.
Surface Tension of Water . The surface tension of water is 72 dynes/cm at 25°C . It would take a force of 72 dynes to break a surface film of water 1 cm long. The surface tension of water decreases significantly with temperature as shown in the graph. The surface tension arises from the polar nature of the water molecule.
Explanation:

How are radiation, convection, and conduction used in green building design?
Answer:
To help reduce energy consumption in air conditioning
Explanation:
Radiation, convection, and conduction are different ways of heat movement, and in green buildings what we want to do is to save energy or use clean energies in all of the devices in the building, having this in mind green building design tries to use the positioning of the sun and air currents to mantain the temperature inside of the building as neutral as possible, fresh on the summer and warm on the winter, this will help lower the amount of energy used to mantain a stable temperature.

Which description most strongly creates a joyful mood? (1 point) Jessie leapt through the door, bobbed and danced down the sidewalk, climbed as high as he could in the dogwood tree, and roared loudly the words from the song "Lollipop, Lollipop." Jessie slumped out the door, wishing he could remember the words from "Lollipop, Lollipop" or some other silly song that would take his mind off his troubles. Jessie stepped through the front door, making a careful note to try to forget the silly song "Lollipop, Lollipop" that was running constantly, painfully through his head. Jessie walked out the door, snapping his fingers and humming the tune from the song "Lollipop, Lollipop" as if he hadn't a care in the world or a thought for tomorrow.
Answer:
"As if he hadnt care in the world or a thought"

Controls and Variables – Read the description for each experiment and answer the questions. Krusty Krabs Breath Mints Mr. Krabs created a secret ingredient for a breath mint that he thinks will "cure" the bad breath people get from eating crabby patties at the Krusty Krab. He asked 100 customers with a history of bad breath to try his new breath mint. He had fifty customers (Group A) eat a breath mint after they finished eating a crabby patty. The other fifty (Group B) also received a breath mint after they finished the sandwich, however, it was just a regular breath mint and did not have the secret ingredient. Both groups were told that they were getting the breath mint that would cure their bad breath. Two hours after eating the crabby patties, thirty customers in Group A and ten customers in Group B reported having better breath than they normally had after eating crabby patties.
1. Which people are in the control group?
Answer:
The people in group B
Explanation:
The people in group B are those in the control group.
The control group during an experiment is a group of experimental subjects that either do not receive the treatment variable or are given placebo treatment. The control group is usually established to create a standard to which comparisons can be made during the course of investigating the effects of a particular variable.
In the case of Krusty Krabs, the group that was given regular breath mint without the secret ingredient (group B) will provide the basis for comparing with the other group that received the mint with the secret ingredient (A).
Hence, the people in group B served as the control group.
If you put a protist into the same three environments, which environment would you expect its contractile vacuole to be most active
Answer: The completed part include the three environment, Hypertonic, isotonic and hypotonic.
The contractile vacuole will be most active in hypotonic environment.
Explanation:
The protist's contractile vacuole will be most active in hypotonic environment because it has lower concentration of solutes outside the cell than other solution which have salt particles which will allow water to constantly entering the cell through osmosis but the protist will counter this by it's contractile vacuole which let out water . The protist contractile vacuole will not hypertonic environment because it will cause the cell to shrink and lose water.
If an ER signal sequence were added to its N-terminus, which structure would the engineered protein adopt
Answer:
The correct answer would be - structure with both N- terminal and C-terminal in the lumen side.
Explanation:
In eukaryotic cells, the cytosol is the site where protein synthesis takes place which is transported to the endoplasmic reticulum. The protein then moves to the endomembrane vesicle pathway from the endoplasmic reticulum. The transport of the proteins to the different organelles takes place from there as they destined and ultimately secreted from the cell.
In ER such proteins that contain ER signals at the N terminal of the protein are move into the lumen of the endoplasmic reticulum. So, both end N- terminal and C-terminal of the protein ae in the side of the ER lumen

Why do we think that some cell signaling molecules have a long evolutionary history?
Answer: Cell signaling involves the relationship between a cell and its receptor which gets the hormones and other agents which controls the activity of the cell.
Explanation:
It can be classified as mechanical or biochemical depending upon the kind of signal. Mechanical signals are the forces produced by the cell or exerted by the cell. Biochemical signals are derived by the biomolecules like proteins, ions, gases, and lipids. These biomolecules have an evolutionary history as they are developed during the primitive atmosphere of earth by the inorganic molecules of carbon dioxide, methane, and water present in the primitive earth's atmosphere. These molecules are basis of development of life as they were responsible for generation of biomolecules like proteins, and lipids necessary for sustaining life on earth.

what happens when rain water hits sand
Answer:
it seapes through the water
Answer:
When rain falls to the ground, the water does not stop moving. Some of it flows along the land surface to streams or lakes, some is used by plants, some evaporates and returns to the atmosphere, and some seeps into the ground. Water seeps into the ground much like a glass of water poured onto a pile of sand.
g A charged tRNA travels across a ribosome from the _______ site, to the _______ site, and then to the _______ site. A; E; P P; A; E P; E; A A; P; E E; P; A
Answer:
A; P; E
Explanation:
A tRNA molecule is a type of RNA found in the ribosomes of a cell. They play a major role in the translation process by binding to the mRNA in respective sites of the ribosome and carrying their corresponding amino acid to the growing polypeptide chain.
Ribosomes, which is the site of translation has three sites namely: A site, P site, and E site. tRNAs perform their roles by moving through these sites in the order: A to P to E.
Site E is the release site

describe the arrangements of epithelial and connective tissues in the four types of membranes.
Answer:
Membranes are thin layers of epithelial tissue usually bound to an underlying layer of connective tissue. Membranes cover, protect, or separate other structures or tissues in the body. The four types of membranes are: 1) cutaneous membranes; 2) serous membranes; 3) mucous membranes; and 4) synovial membranes.
Cutaneous, mucous, serous and synovial membrane have a thin layer of epithelial tissue which is bounded by a connective tissue under it.
What is epithelial tissue?"It is a type of body tissue that forms the covering on all internal and external surfaces of your body, lines body cavities and hollow organs and is the major tissue in glands."What is connective tissue?"It is a tissue that connects, supports, binds, or separates other tissues or organs."What is cutaneous membrane?It is also known as skin.It protects our body's tissue and organs from damage.What is mucous membrane?It is an inner lining of some organs and body cavities that produces mucous.What is serous membrane?"It line body cavities that do not open directly to the outside, and they cover the organs located in those cavities. "What is synovial membrane?These are layer of connective tissue present in joints, cartilages, etc. and they secrete synovial fluid.Hence, all the membranes are formed of epithelial tissue which is bound by an underlying connective tissue.

in what two ways does sun light increase the rate of transpiration
Answer:
mark as brainlliest
Explanation:
Plants transpire more rapidly in the light than in the dark. This is largely because light stimulates the opening of the stomata (mechanism). Light also speeds up transpiration by warming the leaf. Plants transpire more rapidly at higher temperatures because water evaporates more rapidly as the temperature rises
A single base-pair mutation occurs in a promoter sequence of a gene. As a result of the mutation, what are the possible effects on the transcription level of the gene?
Answer:
This mutation could increase, reduce, have no effect, or even eliminate the transcriptional activity
Explanation:
A single pair mutation (also known as point mutation) is caused when only one nucleotide in the DNA sequence is changed. A promoter is a DNA sequence that binds to the RNA polymerase and transcription factors in order to initiate the transcription. When a point mutation results in a promoter region, this may alter transcription, and its effects can be determined by measuring the level of gene transcription. In a promoter bashing assay, point mutations are generated in the promoter region in order to determine their effects on gene expression.
