Which contributes to the movement of air masses
Answer:
The Movement of Air Masses: transporting warm air northward and colder air southward. Counterclockwise winds associated with cyclones transport heat and moisture from lower to higher latitudes and play a significant role in the movement of air masses. A warm front marks the leading edge of this warm, moist air mass.

what is climate ?Climate is defined as a long-term pattern of weather in a specific area. the change weather can occur from hour-to-hour, day-to-day, month-to-month or even year-to-year.
the determination of climate can be occurred by a region’s climate system, this system consist of major components such as the atmosphere, the hydrosphere, the cryosphere, the land surface, and the biosphere.
The atmosphere is the variable part of the climate system where the composition and movement of gases surrounding the Earth can change radically, influenced by natural and human-made factors.
Changes to the hydrosphere, which include variations in temperature and salinity, occur at much slower rates than changes to the atmosphere.

Where is tRNA mRNA and DNA
found in the cell
Answer:
Cytoplasmic tRNAs are found in the fluid inside cells (the cytoplasm). These tRNAs help produce proteins from genes located in the DNA in the nucleus of the cell (nuclear DNA). Although most DNA is nuclear, cellular structures called mitochondria have a small amount of their own DNA, called mitochondrial DNA. and mRNA is found in the nucleus and the cytoplasm in cells.
Explanation:
hope it helps : )
tRNA (transfer RNA) and mRNA (messenger RNA) is found in the cytoplasm of the cell. DNA (deoxyribonucleic acid) is found in the nucleus of the cell.
tRNA plays a crucial role in translating the genetic information carried by mRNA into specific sequences of amino acids during protein synthesis. tRNA molecules are involved in bringing the correct amino acids to the ribosome based on the codons present in the mRNA.
mRNA is synthesized from DNA in the nucleus during a process called transcription. Once produced, mRNA leaves the nucleus and moves into the cytoplasm, where it serves as a template for protein synthesis. In the cytoplasm, mRNA is associated with ribosomes, which are the sites of protein synthesis.
DNA is primarily found in the cell nucleus, where it stores the genetic information of an organism. In some cases, a small amount of DNA can also be found in organelles called mitochondria (in eukaryotic cells) and plastids (in plant cells).

What are the five main functions of nematodes in soil?
Answer:
Nematodes are the bacterial feeders, fungal-feeders, plant parasites, predators, and omnivores.
Explanation:
hope this helps :)
Answer:
Nematodes play an important role in nutrient cycling. In particular, they play a key role in the nitrogen cycle. Nematodes take in nitrogen and excrete it in a form that plants and bacteria can use.
Nematodes graze on bacteria, plants, and other soil organisms. In ecosystems, nematodes play a major role in regulating the populations of their prey organisms.
Nematodes carry fungi and bacteria in and on their bodies. As nematodes move through the ecosystem, they disperse the bacteria and fungi.
Nematodes are a part of food chains and food webs. They are an important food source in many ecosystems.
Nematodes impact the health of other organisms. Some help prevent, or suppress, disease by eating other disease-causing organisms. Other nematodes cause disease in plants and animals.

Identify one process that causes clouds to form in the moist air rising along the frontal boundaries of the low-pressure system.
Answer and Explanation:
The fronts are imaginary lines that separate two air masses of different temperatures. It takes too long for these two masses to mix, causing numerous atmospheric phenomena.
A hot air mass meets a cold air mass. The cold air is heavier and takes a wedge shape under the hot air that rises following a kind of ramp that constitutes the front line.
In the contact area, the hot air cools to the point of condensation and forms clouds that cause precipitation. These warm fronts originate weak but continuous rains.
If you were to expose cells that are undergoing aerobic respiration to a radioactive carbon isotope in the form of C6H12O6, which of the following molecules would you not expect to be radiolabeled?
(a) pyruvate
(b) NADH
(c) water
(d) CO2
Answer:
The correct answer is option (c) "water".
Explanation:
Cells that are undergoing aerobic respiration and are exposed to a radioactive carbon isotope in the form of C6H12O6 will have radiolabeled its molecules that are involved in aerobic respiration and contain carbon. In this case, the only molecule that does not contain carbon in the options is water, therefore water will not be radiolabeled. Water is comprised of two atoms of hydrogen and one atom of oxygen, while pyruvate, NADH and CO2 all contain carbon.

Explanation:
A: Venus rotates far more slowly than Earth
Look at the column that says Period of Rotation.
Venus has a rotation period of 243 days.
Earth has a rotation period of about 24 hours.
243 days is much longer than 24 hours, so this is true.
B: Venus's year is longer than Earth's.
The year is also another way to say Period of Revolution.
Venus's is about 224 days.
Earth's is about 365 days.
Venus's is actually shorter, so this is false.
C: Mercury is approximately twice the size of Earth.
Let's look at the Equatorial Diameter column.
Mercury's is 4,880 km.
Earth's is 12,756 km.
Mercury's is much smaller than Earth's, so this is false.
D: All of the above.
Since B and C are both not true, this is incorrect.
Therefore, the correct answer is A: Venus rotates far more slowly than Earth.

They are not on the same chromosome because when genes are located on different chromosomes they segregate independently.
How do you know if genes are on the same chromosome?We say that a gene is in linkage or gene linkage when it is on the same chromosome and does not segregate independently at the time of the formation of a gamete. We know that chromosomes are formed by a large sequence of genes that is responsible for determining the characteristics of a species.
Whit this information, we can conclude that they are not on the same chromosome because when genes are located on different chromosomes they segregate independently.

So far, we have primarily discussed human adaptations independently of one another. In real life, of course, each person has numerous coexisting ancestral adaptations. Ignore what you know of your family history and consider only your physical traits for the following adaptations: skin color, lactose tolerance, and body shape. Based on these three traits, in what part of the world might your ancestors have originated? Do all three of your traits suggest similar ancestry? Be sure to explain your hypothesized determination using evidence related to all three traits, and be sure to think about all the forces of evolution that might impact your unique history (such as gene flow and founder effect).
Answer:
about skin coloration:
Regarding these modifications, we can say that it influences not only the knowledge of evolution but also on the development of strategies for the management of many diseases, so we know that these changes are not produced by a single agent and factors such as Melanin, a substance produced by melanocytes and which gives the tint to each tone, also includes influences such as exposure to sunlight, both in frequency and geographical area from which it is made. Keratin is also found as its own dermal factor. According to this, there has been an adaptation of the phenotype of each individual mainly to the UV environmental factor that can make changes and modify skin tone.
About lactose tolerance:
It is known that historically, after childhood for many people it was very difficult to continue consuming milk, because the enzyme lactase was not found in them and lactose digestion became very difficult, nowadays it is believed that the weather has influenced to improve digestion
About the body shape:
The inherited factors are very important, from the different habitats of our ancestors, which for reasons of hunting, solar exposure, type of food, were being inherited, today it is known that there are 3 main forms of body types including the endomorph, ectomorph and mesomorph, the main advantages depending on where the individual lives will adapt to persist in the next generation, as well as to use new ways of obtaining food can modify it
