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.

It’s D
Explanation:
what opposes the sliding motion of two
surfaces that are in contact.
Answer:
Friction: A force that opposes the motion of objects that touch as they move past each other. Friction acts at the surface where objects are in contact.
Explanation:
The force that acts against your pushing force is called friction. is a force that resists the motion between two surfaces in contact. When you try to slide two surfaces across each other, the force of friction resists the sliding motion.

Explanation:
Anya and Greg are working in their research laboratory. Anya tells Greg that one of the mice has a 50% probability of having the alleles DD and a 50% probability of having the alleles Dd. How can Anya explain her reasoning? In two out of 50 times, the mouse has the alleles DD or Dd. The probability that the mouse has the alleles DD is equal to the probability that it has the alleles Dd. The mouse is twice as likely to have the alleles DD than it is to have the alleles Dd. There are two more possible outcomes besides the mouse having DD or Dd alleles.
Answer:
Option B: The probability that the mouse has the alleles DD is equal to the probability that it has the alleles Dd.
Explanation:
Anya tells Greg that one of the mice has a 50% probability of having the alleles DD and a 50% probability of having the alleles Dd.
She can explain her reasoning by saying that both pairs of alleles (DD and Dd) has equal chance of being expressed i e, the probability that the mouse has the alleles DD is equal to the probability that it has the alleles Dd. Both pairs each has 0.5 chance of occuring.
Answer:
Explanation:
A Dominant Allele is an Allele that express itself.
DD- this represent a dominant homozygous allele
Dd- represent a dominant heterozygous allele
When an individual with DD is crossed with Dd we will have DD,Dd,DD,Dd
Phenotypic ratio is 2:2
i.e homozgous dominant crosses with heterozygous dominant
which means both DD and Dd have 50% chance of occuring in the genotype and the probabality is the same.
Note that in the phenotype of an individual with homozygous dominant (DD) is the same phenotype with heterozygous dominant(Dd)
How does the impact of disease in a stressed reef compare to the impact of disease in a healthy reef?

Explain the term overexploitation as it relates to species extinction.
Answer:
When a resource is over consumed to the point of diminishing it. in the context of species extinction, if an animal population, say fish like anchovies, were to be fished for and eaten so much that they would have no chance to recover their numbers as they are eaten, it would be overexploitation. Hope this helps.
Depending on the organism, the number of____in a cell may change.
Answer:
chromosomes
Explanation:
In tomatoes, round fruit (R) is dominant over long fruit (r), and smooth skin (S) is dominant over fuzzy skin (s). A true-breeding round, smooth tomato (RRSS) was crossed with a true-breeding long, fuzzy tomato (rrss). All the F1 offspring were round and smooth (RsRs). When these F1 plants were bred there were 43 round smooth offspring and 13 long, fuzzy offspring. Are these two genes likely to be on the same chromosome? Explain.
Answer:
Round, smooth: 43
Long, fuzzy: 13
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.

What happens during interphase that allows the two resulting cells to be the same as the
original cell?
Answer:
During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. ... Then, at a critical point during interphase (called the S phase), the cell duplicates its chromosomes and ensures its systems are ready for cell division.

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.

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

Drag each label to the correct location on the map.
Identify the types of precipitation on the map. The color scale gives the rainfall amounts in inches.
The given question is incomplete as it lacks the map which is important, however the correct answer is attached:
Answer:
The correct answer is -
Top box (green area) - moderate rain,
Middle box (sky blue area) - light rain, and
Bottom box (red area) - heavy rain.
Explanation:
As per the map and the scale presented on the map that indicates the rainfall in inches. The green area indicates that the rain fall in this area is one inch which is moderate as the the sky blue rainfall measurement is .5 inches which is half. However, the red area is the highest rainfall area in comparison to both of these which is about four inches.
On the basis of these it we can label all three boxes as per their rainfall amount that is,
Top box (green area) - moderate rain,
Middle box (sky blue area) - light rain, and
Bottom box (red area) - heavy rain.

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.

hello i need help on my last question this question is a bonus point to anyone who answer it
Answer:
A
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.
Is this right please ASAP
