what happens when air masses of different temperatures meet?
Answer: When two air masses meet together, the boundary between the two is called a weather front. At a front, the two air masses have different densities, based on temperature, and do not easily mix. ... Winds are common at a front. The greater the temperature difference between the two air masses, the stronger the winds will be.
Explanation:
What the relationship between a glucose molecule and the products it makes during cellular respiration.
Answer:
During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called oxidative phosphorylation.
During cellular respiration, glucose makes water, carbon dioxide, ATP, lactic acid, and ethanol. In the absence of oxygen, ethanol and lactic acid are formed from the glucose.
What is glycolysis?
Glycolysis is a process in which glucose breaks down inside a cell. Glucose makes pyruvate as an end product in this process. In the presence of oxygen, glucose breaks down into pyruvate and proceeds to the Krebs cycle. In this process, ATP, water, and carbon dioxide are released.
In the absence of oxygen, glucose is converted into lactic acid and ethanol. This is called fermentation and produces only 2 ATP from glucose. This is called anaerobic respiration.
When oxygen is present from glucose, nearly 36-38 ATP are formed. Pyruvate converts into acetyl CoA, and it enters the Krebs cycle. A complete oxidation of glucose takes place in the presence of oxygen.
Hence, in the presence of oxygen, 36-38 ATP is released from glucose, and in the absence of oxygen, lactic acid and ethanol are produced with 2 ATP.

How are a hypothesis and a theory similar?
Answer:
A hypothesis is either a suggested explanation for an observable phenomenon, or a reasoned prediction of a possible causal correlation among multiple phenomena. In science, a theory is a tested, well-substantiated, unifying explanation for a set of verified, proven factors.
What would be the speed of a wave with low tension, a distance of 8.5 cm and a time of 3.25 seconds?
The speed of the wave will be 0.026 m/s
The speed of a wave is the distance traveled by a given point on the wave (such as a crest or trough) in a given interval of time.
Speed is given by the formula
[tex]Speed = \frac{Distance}{Time}[/tex]
From the question,
Distance = 8.5 cm
First, convert this to meter
Recall:
100cm = 1m
∴ [tex]8.5 cm = \frac{8.5}{100}[/tex] m
8.5 cm = 0.085m
and
Time = 3.25 seconds
Now, putting the above parameters into the equation
[tex]Speed = \frac{Distance}{Time}[/tex]
∴ [tex]Speed = \frac{0.085}{3.25}[/tex]
Speed = 0.026 m/s
Hence, the speed of the wave will be 0.026 m/s

the pigment-producing cells of the epidermis are located in which layer?
Answer:
Basal Layer
Explanation:
Melanocytes are found in the basal layer of the epidermis. These cells produce a pigment called melanin, which is responsible for different skin color. Melanin is packaged into small parcels (or melanosomes), which are then transferred to keratinocytes.
how does the loss of species affect the entire ecosystem
Answer:
Declining biodiversity lowers an ecosystem's productivity (the amount of food energy that is converted into the biomass) and lowers the quality of the ecosystem's services (which often include maintaining the soil, purifying water that runs through it, and supplying food and shade, etc.).
Answer:
"When a species becomes extinct, they reduce the variety of animals, plants, or bird species from that ecosystem resulting in the extinction of the other species that were dependent on them. Different species are playing different roles in the ecosystem to maintain a balance of the world." Credits to outside sources that it won't let me say :(

can anyone writet about describing ● History of Ribosomes.
Answer:
The ribosome is a complex molecule made of ribosomal RNA molecules and proteins that form a factory for protein synthesis in cells. In 1955, George E. Palade discovered ribosomes and described them as small particles in the cytoplasm that preferentially associated with the endoplasmic reticulum membrane. Along with other scientists, Palade discovered that ribosomes performed protein synthesis in cells, and he was awarded the Nobel Prize in 1974 for his work.
Each ribosome has a large component and a small component that together form a single unit composed of several ribosomal RNA molecules and dozens of proteins. The ribosome is responsible for translating encoded messages from messenger RNA molecules to synthesize proteins from amino acids. The ribosome translates each codon, or set of three nucleotides, of the mRNA template and matches it with the appropriate amino acid in a process called translation. The amino acid is provided by a transfer RNA (tRNA) molecule. Each newly translated amino acid is then added to the growing protein chain until the ribosome completes the process of protein synthesis.
the red blood cells and brain are two body tissues that derive most of their energy from
[tex] \huge \mathfrak{{ \pmb{ \underline{ \red{Answer}}}}}[/tex]
The red blood cells and brain are two body tissues that derive most of their energy from glucose.
Glucose is the answer.
The red blood cells and brain are two body tissues that derive most of their energy from carbohydrates. The correct option is C.
What are carbohydrates?Sugar molecules make up carbohydrates, or carbs. Carbohydrates are one of the three primary nutrients included in foods and beverages, along with proteins and fats.
Glucose is created by your body's breakdown of carbs. The primary source of energy for the cells, tissues, and organs in your body is glucose, sometimes known as blood sugar.
Under normal conditions, glucose serves as the brain's main energy source.
Using either glycolysis or oxidative phosphorylation—the latter of which is 15 times more efficient—glucose is used to create energy in the form of adenosine triphosphate (ATP).
In the absence of glucose, the brain has backup energy sources, such as ketones created by fatty acid metabolism, which predominantly takes place in the liver.
These include 3-hydroxybutyrate, acetone, and acetoacetate (3BHM).
Thus, the correct option is C.
