Chromosomal mutations are different from point mutations in that
Answer:
Point mutation is a change to a single nucleotide letter at a single point. Hence the name.
Chromosomal mutations are deletions, rearrangements or translocations a of large sections of DNA.
Both can have effects ranging from harmless to fatal/non viable.
A point mutation could be in a region that does not code protein (and thus likely harmless) or it could introduce an early stop to translation of a gene into a protein (which could be deadly)
Chromosomal rearrangements might have the breakpoints in non gene coding regions and so be harmless or the break points could interrupt the function of vital genes .

Hello. This question is incomplete. The full question is:
Energy and matter cycle through a beach ecosystem on the Gulf of Mexico. Identify one kind of model you can use to show the path of energy and matter through this ecosystem. Describe one benefit of using that kind of model to show those processes.
Food web; shows energy available at each trophic level for the next group of organisms
Energy pyramid; show all pathways of energy flow in an ecosystem
Food chain; shows a single pathway of energy flowing, making it easy to see which organisms are primary, secondary and tertiary consumers
Answer:
Food chain; shows a single pathway of energy flowing, making it easy to see which organisms are primary, secondary and tertiary consumers
Explanation:
The food chain represents a linear sequence of energy transfer within an environment. This transfer is carried out with a sequence of living beings that serve as food for each other and this food that promotes the transfer of energy through a single path, allowing all levels of transmission to be observed, through primary, secondary and tertiary.

Describe the order of succession for the regrowth of
the fire destroyed forest.
Explanation:
Primary succession is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and other organisms usually lacking soil, such as a lava flow or area left from retreated glacier, is deposited.[1] In other words, it is the gradual growth of an ecosystem over a longer period of time.[2][3]
Primary succession occurring over time. The soil depths increase with respect to the increase in decomposition of organic matter. and there is a gradual increase of species diversity in the ecosystem. The labels I-VII represent the different stages of primary succession. I-bare rocks, II-pioneers (mosses, lichen, algae, fungi), III-annual herbaceous plants, IV-perennial herbaceous plants and grasses, V-shrubs, VI-shade intolerant trees, VII-shade tolerant trees.
Primary succession on Rangitoto Island
In contrast, secondary succession occurs on substrate that previously supported vegetation before an ecological disturbance from smaller things like floods, hurricanes, tornadoes, and fires which destroyed the plant life.[4]

3.- Cuáles son los parámetros para la valoración de los efectos producidos por los impactos ambientales
Answer:
Los parámetros son: magnitud, extensión, persistencia, reversibilidad, recuperación, persistencia, sinergia, probabilidad de ocurrencia, relación causa y efecto
Explanation:
La evaluación de un impacto ambiental debe tener en cuenta los siguientes parámetros principales:
- Magnitud. La magnitud se refiere al hecho que un impacto ambiental puede afectar al ecosistema en diferentes niveles.
- Extensión. Este término se refiere a la superficie (por ejemplo, en metros cuadrados) del ecosistema el cual ha sufrido el impacto.
-Reversibilidad. La reversibilidad indica la probabilidad de que el ecosistema una vez que ha sufrido el impacto pueda regresar a su estado inicial.
- Recuperación. La recuperación es el grado de restauración al que puede llegar el medioambiente una vez sufrido el impacto.
- Persistencia. La persistencia indica la duración (cuantificable en tiempo) del impacto ambiental.
- Sinergia. La sinergia se refiere al hecho de que dos o más impactos ambientales poseen un efecto mayor sobre el ecosistema que el producido mediante varios impactos ambientales por separado.
- Probabilidad de ocurrencia. La probabilidad de ocurrencia expresa la posibilidad de que un impacto ambiental se produzca en un ecosistema durante un determinado período de tiempo.
- Relación causa y efecto. La relación causa y efecto clasifica a los impactos ambientales en directos (causados por el impacto) e indirectos (causados por las consecuencias derivadas del impacto).
The relative difference in charge across a plasma membrane is the ____________ in an inactive excitable cell. A ____________ is used to measure the voltage difference across the plasma membrane. This is done by placing one microelectrode into the ____________ and the other microelectrode outside the neuron into the ____________ . The RMP has a value that is typically ____________ millivolts. More positive ions reside ____________ a neuron than ____________ a neuron when it is at rest.
Answer:
Resting membrane potential; voltmeter; neuron; interstitial fluid; -70; outside; inside.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles. Some examples of cell organelles with their respective functions in all living organisms such as trees, birds, and bacteria include; nucleus, cytoplasm, cell membrane, golgi apparatus, mitochondria, lysosomes, ribosomes, chromosomes, endoplasmic reticulum, vesicles, etc.
The relative difference in charge across a plasma membrane is the resting membrane potential in an inactive excitable cell. A voltmeter is used to measure the voltage difference across the plasma membrane. This is done by placing one microelectrode into the neuron and the other microelectrode outside the neuron into the interstitial fluid. The RMP has a value that is typically -70 millivolts. More positive ions reside outside a neuron than inside a neuron when it is at rest.

Answer:
One difference between these cells is plant cell has chloroplast but animal cell does not have chloroplast.
Another difference between these is that plant cell has cell wall but animal cell does not have cell wall.
Explanation:
Plant cell are known to cells that possess chloroplast. These chloroplast contain chlorophyll which enables the plants to manufacture their own food. Animal cell does not possess chloroplast which makes it impossible for animals to manufacture their own food.
Plant cell actually have cell wall and a cell membrane but animal cell does not have cell wall but only possesses cell membrane. The cell wall gives mechanical strength and maintains cell shape.

Analisa and Mateo, two research anthropologists interested in deciphering the relatedness between four extinct primates, were studying the similarities and differences among a number of measurements of the complex structures of the jaw fragments they collected, as well as making many other morphological contrasts between other fossilized bones from dozens of collected specimens. In the lab, they noticed the lengths of the bones of the leg, particularly the femur, tibia, and fibula, were very different in all the specimens, whereas the jaw structures were nearly identical among the specimens. What should they tentatively conclude based on this evidence
The group of choices associated with the question is as follows:
A)The four primates likely share a close common ancestor or could potentially be the same species based upon the jaw measurements.
B)The hominids with the most closely matching leg bone measurements are likely more closely related than the others, due to the importance of locomotion as an evolutionary adaptation.
C)The femur measurements are not important.
D)Because the measurements of the leg bones vary widely, it is probable that the four species are from different genera.
Answer:
The correct answer is - The four primates likely share a close common ancestor or could potentially be the same species based upon the jaw measurements.
Explanation:
On the basis of the research, it is found that the four primates have similar jaw structure and measurement and have a distinct length of bones of the leg.
The given research and founding suggests that all four primates most likely share a close common ancestor or diverge from the same species based on her jaw measurements.
