What type of moisture does Colder air hold than hotter air?
When the humidity is high, the change of precipitation is (high or low).
What happens to the humidity if the temperature drops and the amount of moisture in the air remains the same?
Answer:
Explanation:
1)A oft-repeated water vapor myth is that warm air can “hold” more water vapor than cool air because as the air warms its molecules move farther apart, making room for more molecules..
2)Humidity is both the precursor and the result of rain. Humidity is water vapor in the air. It turns to rain when temperatures drop sufficiently to cause this water vapor to condense into water droplets.
3) If the water vapor content stays the same and the temperature drops, the relative humidity increases. If the water vapor content stays the same and the temperature rises, the relative humidity decreases.
\

Answer:
The chance of precipitation is high.
Colder air holds less moisture than hotter air
If the temperature drops the humidity stays the same and yes the humidity stays the same when temperature drops but rises when there is hot air

Some. produces variable traits depending on environmental conditions
Answer:
Some genes produces variable traits depending on environmental conditions
Explanation:
The interaction between some genes and environments confers on individuals different degrees of susceptibility in the appearance of a certain characteristic or in the expression of some variable traits. The trait appears in individuals who have reached a certain threshold, thus the variability in phenotypic expression could be related to the greater or lesser number of predisposing genes in each individual. The differential expression of genes depending on the environment is called the reaction norm, and it refers to genes that can be expressed in a different way in different individuals, depending on the environment in which those individuals develop. The norm of reaction is the set of pathways that a genotype can follow, in all favorable and unfavorable environments, until giving rise to the various possible phenotypes.

How do high-energy electrons from glycolysis and the Krebs cycle contribute to the formation of ATP from ADP in the electron transport chain?
O
A. High-energy electrons interact with pyruvic acid to create a phosphate bond with ADP, forming ATP.
O
B. High-energy electrons supply the needed energy to synthesize ATP from the lower-energy ADP in the electron transport chain
C. High-energy electrons supply a negative charge which causes the citric acid to oxidize, forming a phosphate group to bond with ADP.
O
D. High-energy electrons increase the temperature of ADP so it easily reacts to form ATP.
Answer:
b
Explanation:
High-energy electrons supply the needed energy to synthesize ATP from the lower-energy ADP in the electron transport chain. So, the correct option is (B).
What is Electron transport chain?An electron transport chain is defined as a series of protein complexes and other molecules that transfer electrons from electron donors to electron acceptors through redox reactions and that link this electron transfer with the transfer of protons across a membrane.
Large amounts of ATP can be produced through a highly efficient method called oxidative phosphorylation where ATP is a fundamental unit of the metabolic process. Electrons are transferred from electron donor to electron acceptor thereby producing ATP which is the important step of Electron transport chain.
Thus, high-energy electrons supply the needed energy to synthesize ATP from the lower-energy ADP in the electron transport chain. So, the correct option is (B).

When an instruction for a variation of a trait is not shown in by the organism, but the organism carrys it and can pass it on to the next generations, these organisms are called _______.
a
dominant
b
carriers
c
recessive
d

Answer:
b. carriers
Explanation:
Recessive alleles do not create a phenotype if a dominant allele is present BUT the organism itself is called a carrier because it carries the recessive trait.
Match each movement with the correct label.
flexion
extension
adduction
abduction
elevation
depression
medial rotation
lateral rotation
Answer:
flexion - depression
extension - elevation
adduction - medial rotation
abduction - lateral rotation
Explanation:
Flexion is the process of bending an arm or leg. It occurs as a result of the contraction of the muscles. Depression is a downward movement. Hence, flexion refers to the depression of an arm or leg.
Extension is the process of stretching the body parts. Elevation is an upward movement. Hence, extension refers to the elevation of body parts.
Adduction is the movement of a limb or other part of the body towards the midline or another part of the body. The movement of the limb towards the midline of the body is known as medial rotation.
Abduction is the movement of a limb or other part of the body away from the midline of the body. The movement of the limb away from the midline of the body is known as lateral rotation.

List at least two variables that might influence the rate of cellular respiration.
Answer:
Answer below !
Explanation:
1) Oxygen Concentration
2) Temperature
3) Glucose Availability
Hope I helped and have a great day ∩^·ω·^∩ !
Cellular respiration in living tissues is reduced at low temperatures. The amount of kinetic energy needed for chemical reactions like cellular respiration to occur decreases as temperature rises.
What variable that influence the rate of cellular respiration?Since all living cells require both glucose and oxygen to operate properly, variations in the concentration of glucose have an effect on the rate of cellular respiration. If a cell's glucose level is low, it cannot produce energy in the form of ATP molecules.
High oxygen concentrations enable cells to perform aerobic respiration, which uses oxygen to build ATP and generates more ATP than anaerobic respiration, which occurs when oxygen is not present.
As a result, increased cellular respiration is often associated with warmer temperatures.
Therefore, Oxygen Concentration, Temperature, Glucose Availability

High cholesterol and triglycerides may indicate cardiovascular disease. What happens when cholesterol and other lipids are deposited in artery walls?
Answer:
With high cholesterol, you can develop fatty deposits in your blood vessels. Eventually, these deposits grow, making it difficult for enough blood to flow through your arteries. Sometimes, those deposits can break suddenly and form a clot that causes a heart attack or stroke.

Answer:
The energy that goes into the trumpet to create the sound is a standing wave. (I think...)
Explanation:
When a person is blowing into a trumpet, a standing wave is being created based on the shape of the instrument. The trumpet is formed to produce sound. Notes sound different from one another because they represent different frequencies and therefore a different numbers of nodes.
why is there is no point in adding more generations when an allele has become fixed
Answer:
Low genetic diversity, which is seen with allele fixation, is dangerous as it can lead to mass extinctions. If there is little genetic variability within a population and the genetically similar individuals all are susceptible to a certain pathogen, the population will likely cease to exist. This is why we see examples of populations with fixed alleles becoming threatened or endangered
Explanation:
basically, it will cause extinction

1. are marsupials discussed to prove against biogeography/ geographic distribution. SHOW YOUR EXPLANATION!!
Answer:Marsupial mammals on Australia likely evolved from a common ancestor. ... Because Australia was isolated by water for millions of years, these species were able to evolve without competition from (or exchange with) mammal species elsewhere in the world.
Explanation:
Answer:
Biogeography is the study of the geographical distributions of biological organisms. For scientists who study evolution, biogeography is often an important part of their analysis, because it provides compelling proof for their theory. This is because many geographical features, such as oceans, rivers, mountains and islands, provide barriers to species, allowing scientists to observe how they evolve separately from one another.
