Answer:
3 types of front: cold front (cool air and cumulus clouds are replaced by stratus and stratocumulus clouds or clear skies) , warm front ( warm air and high clouds like cirrus), and stationary front(warm and cool air and stratus, nimbostratus, altostratus, and cirrostratus clouds.
Explanation:
Cold fronts form when a cooler air mass moves into an area of warmer air in the wake of a developing extratropical cyclone. The warmer air interacts with the cooler air mass along the boundary, and usually produces precipitation. Cold fronts often follow a warm front or squall line.
Warm front Forms when a moist, warm air mass slides up and over a cold air mass. As the warm air mass rises, it condenses into a broad area of clouds. A warm front brings gentle rain or light snow, followed by warmer, milder weather.
Stationary front Forms when warm and cold air meet and neither air mass has the force to move the other. They remain stationary, or “standing still.” Where the warm and cold air meet, clouds and fog form, and it may rain or snow.
Compare and contrast the TWO classes of "seeded "plants.
Answer:
The seed plants are often divided arbitrarily into two groups: the gymnosperms and the angiosperms. The basis for this distinction is that angiosperms produce flowers, while the gymnosperms do not.
Explanation:
The seed plants are often divided arbitrarily into two groups: the gymnosperms and the angiosperms. The basis for this distinction is that angiosperms produce flowers, while the gymnosperms do not. This is poor form, since it defines the gymnosperms by the absence of a character, and not by any features that the organisms actually share. The gymnosperms do share a number of features, but, as should be obvious from the above cladogram, they are not more closely related to each other than to the angiosperms (Anthophyta). The features shared by gymnosperms were likely present in the early ancestors of the flowering plants as well. It should also be noted that the "progymnosperms" are represented by a box of a different color, in order to make it clear that they are not actually seed plants, but rather are included here because they are believed to be the closest relatives of the seed plants.
Systematics within the seed plants is poorly understood. Part of the problem is that most of the major groups have gone extinct, and several of the groups alive today consist primarily of plants with highly derived morphologies. The above cladogram is based largely on the work of Jim Doyle, a professor at UC Davis, and Michael Donoghue, currently at Harvard, and is therefore somewhat preliminary. It includes some questionable groupings not explicitly supported in their papers.

1 gram of fat give about how much kj of energy
Answer:
37 kj
Explanation:
1 gram of fat = 9 kilocalories (kcal)
1 kcal = 4.2 kilojoules (kj)
4.2 kj/kcal * 9 kcal = 37.8 kj
1 gram of fat = 37.8 kJ

Considering the connections between Yellowstone’s wolves, aspen and willow trees, and elk; which one is the keystone species.
Answer:
The keystone species is the wolf.
Explanation:
Every species of organism is important to the ecosystem, so if just one species gets extinct for whatever reason there will be consequences for the other species. How big the consequences will be, depends on the species and on how big of an effect it has on the ecosystem. Some species have relatively small importance, while some have huge importance, and the ones that have huge importance are called keystone species.
The keystone species have such big importance to an ecosystem that with their presence everything is under control, but if they go extinct then the ecosystem suffers badly and changes dramatically. In this case, a keystone species is the wolf. The wolves control the elk population, which in turn means that there is no shortage of food for the elk and they don't damage the young trees. By not damaging the young trees, they grow, so there is a much larger area covered by forest. More forest means less erosion, the water of the streams is better controlled, and there is less meandering. If the wolves are out of the picture, as they were for some time, the picture is totally opposite.

what is an important step in the process of translation?
Answer: There are three major steps to translation: Initiation, Elongation, and Termination. The ribosome is made of two separate subunits: the small subunit and the large subunit. During initiation the small subunit attaches to the 5' end of mRNA. It then moves in the 5' → 3' direction.

Identify one organism, one population, and one community
Answer:
The study of organisms, populations and communities examines how organisms interact with each other and their environment at individual, population and community levels. To characterize these interactions, NEON quantifies and observes interactions among multiple organisms and their environments. By sampling a variety of organisms in aquatic and terrestrial systems, NEON provides data on individual traits, population dynamics and the composition of communities. Integrated with other data collected across NEON sites, the project produces data in the areas of biodiversity, infectious diseases and invasive species.

The diagram below shows two different forces acting on a cyclist riding a bicycle the total mass of the cyclist and the bicycle is 100.0 kg based on information what is the acceleration of the cyclist?
Answer:b
Explanation:
The diagram below shows two different forces acting on a cyclist riding a bicycle is 150 N and another force acting opposite to moving cycle is 84 N the total mass of the cyclist and the bicycle is 100.0 kg based on information. Thus, option B is correct.
How net force will be calculated?
The net force acting on the bicycle is:-
F net = Total force acting on bicycle
In above question,
Given the F1 = 150 N and F2 = -84 N (Negative sign shows that force is acting opposite to the motion)
So,
Fnet = F1 + F2
Fnet = 150 N -84 N
Fnet = 66 N
Now the acceleration will be
Fnet = mass X acceleration
In above question,
Fnet = 66 N
Mass = 100 Kg
So,
Acceleration = Fnet/Mass
Acceleration = 66/100
Acceleration = 0.66 m/sec^2
Therefore, The diagram below shows two different forces acting on a cyclist riding a bicycle is 150 N and another force acting opposite to moving cycle is 84 N the total mass of the cyclist and the bicycle is 100.0 kg based on information. Thus, option B is correct.

An organism's DNA determines the traits it will haveWhich statement correctly explains how DNA determines the organism's traits?
Answer:
This question is incomplete as it lacks options, the options are:
1- The sugar and phosphate groups that make up the backbone are used in different sequences to encode an organism’s traits.
2- The bases A, T, C, and G are always present in equal amounts, so each organism is unique.
3- The bases A, T, C, and G in DNA are used in different sequences to encode an organism’s traits.
4- The bases A, T, C, and G are always in the same order in each organism, so each organism is unique.
The answer is 3. The bases A, T, C, and G in DNA are used in different sequences to encode an organism’s traits.
Explanation:
Deoxyribonucleic acid (DNA) is the genetic material in the cells of living organisms. It is a polymer biomolecule made up of nucleotides monomers. The DNA contains information that encodes the synthesis of useful products (proteins), which determines the traits in organisms.
A DNA molecule is made up of four nucleotide subunits viz: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). These bases, which are used in different sequences, carry the information that encodes an organism's trait.

Moose populations would decrease as the moose emigrate to safer habitats
Moose populations would increase since the moose and deer can breed creating resistant moose.
Moose populations would decrease as the worm is a biotic factor that will limit the growth of their population
Moose populations would increase as weak moose are killed allowing stronger moose to give birth or immigrate into the area.
