Answer: Such similarity is the result of CONVERGENT EVOLUTION
Explanation:
Evolution can be defined as the theory that was developed based on the findings of scientists that living organisms are descended from a common ancestor.
The current theory of the process of evolution makes use of present day knowledge of genes and chromosomes to explain the source of genetic variation upon which natural selection works. It postulates that although natural selection is the only force that regularly produces adaptive evolutionary change, other forces too play a part in evolution.
Evolutionary changes may show the following patterns:
--> one species gradually transform into another species.
--> one or more species evolve as offshoots of a single ancestral species to fill a wide variety of habitat. This is known as divergent evolution.
--> Many superficially similar looking species arise from different ancestral species. This is known as CONVERGENT EVOLUTION. It is shown by organisms occupying very similar kinds of environment. That is why a porpoise and a shark seem closely related, but they are not.
Put the following in order from smallest to largest.
- protein
- eukaryotic cell (has nucleus)
- virus (NOT alive)
- prokaryote (bacteria, no nucleus)
Answer:
Protein → virus → prokaryotic cell → eukaryotic cell
Explanation:
This question is asking to place the following components of organisms in an ascending order of magnitude i.e. from smallest to largest.
- Proteins are macromolecules that are found in living cells where they serve different functions. Since they are found inside cells, they are the smallest on this list.
- Viruses are microorganisms considered to be non-living because they do not show characteristics of living things. Viruses are pathogenic organisms that attack living cells. They are the smallest microbes found having sizes in nanometers (nm).
- Prokaryotes are group of organisms with no nucleus e.g bacteria. They possess cells that are smaller than that of eukaryotes.
- Eukaryotic cells i.e. cells with nucleus, have the biggest size of any cell. Hence, they are the largest in the list.
Based on the above description, the ascending order of magnitude is as follows: Protein → virus → prokaryotic cell → eukaryotic cell

Consider the 4 foods in order of the percent by mass of proteins, from lowest to highest. From food to food, as the percent by mass of proteins increased, the mass of food remaining at 28 hr: 1 point A. increased only. B. decreased only. C. increased and then decreased. D. decreased and then increased.
Answer:
B. decreased only
Explanation:
If you look at the table 1 and order the foods by the percent of protein, and after you take a look at the graph, you'll see that the bigger the percentage of protein, less food remains.
The frequency of a wave does not change as it passes from one medium to another.
What will most likely happen if a light wave moves from the air into a solid?
O The wavelength of the light wave will increase.
O The speed of the light wave will decrease.
O The wavelength of the light wave will remain the same.
O The speed of the light wave will remain the same.
Answer:
The speed of the light waves will decrease
The frequency of a wave does not change as it passes from one medium to another.The wavelength of the light wave will increase. Thus, option A is correct.
What is a frequency table?The columns of the frequency table are two. The categories of the data are listed in the first column. The frequency of each category, or the number of the data values in the category, is listed in the second column.
The distribution of the observations based on a variable's possible values is shown in a frequency table. To understand the alternatives appear more or less often in the dataset, frequency tables are the useful. This has been considered as useful for better understanding each variable and determining whether or not variables need to be recorded.
Therefore, the frequency table has been just a two-column "t-chart" or table that lists all of the potential outcomes and their corresponding frequencies as seen in a sample.

which type of feature forms suddenly where intense compression deforms the rock area
Answer: The options are not given, here are the options gotten from another site.
A. volcano
b. normal fault
C. folded layers
D. reverse fault
The correct answer is Reverse fault.
Explanation:
This is because Reverse fault is caused by compressional stress which means rocks pushing over each other. It is the opposite of normal fault.
Reverse faults are exactly the opposite of normal faults.which occur when the hanging wall rises above and it is also relative to the footwall. Reverse faults plane are vertical and occur in areas with compression (squishing).

¿Cuáles de las siguientes características permite el intercambio gaseoso entre el Oxígeno (O2) y Dióxido de carbono (CO2) en los alveolos?
Answer:
Difusión y afinidad de la hemoglobina.
Explicación:
La difusión y afinidad de la hemoglobina son las características que permiten el intercambio gaseoso entre el Oxígeno (O2) y el Dióxido de Carbono (CO2) en los alvéolos. Debido a la difusión, las células de hemoglobina descargan o eliminan el gas de dióxido de carbono que es más alto en la hemoglobina en comparación con los alvéolos, por lo que el dióxido de carbono se mueve de la hemoglobina a los alvéolos mientras que, por otro lado, el oxígeno se mueve dentro de la célula de hemoglobina a través de la difusión y la estructura de la hemoglobina atraer y adherir moléculas de oxígeno consigo mismo.

Which population eats kelp the most?
Answer:
bristle worms
Explanation:
In kelp forests, the most commonly found invertebrates are bristle worms, scud, prawn, snails, and brittle stars. These animals feed on the holdfasts that keep kelp anchored to the bottom of the ocean and algae that are abundant in kelp forests. Sea urchins will often completely remove kelp plants by eating through their holdfasts. Other invertebrates found in kelp forests are sea stars, anemones, crabs, and jellyfish.

9. If you conducted the analysis portion of Experiment 2, you calculated
the rate at which the percentage of fish with a complete pelvis
decreased in that ancient lake. Do you think the same rate of change
would apply to modern fish populations?
A. Probably not, since the environment has changed so much in the 10
million years since that ancient lake existed.
B. Although we did not measure this directly, it is possible that the same
rate of change observed in the fossil record applies to modern
populations.
C. The fossil record analyzed in Experiment 2 only spans 15,000 years,
so we cannot draw any conclusions to modern populations, which
evolved over a much longer period of time, at least 10,000 years.
D. The rate of evolution of a particular phenotype cannot be calculated
from the fossil record because the fossil record is always fragmentary.
Answer: Although we did not measure this directly, it is possible that the same rate of change observed in the fossil record applies to modern populations.
Explanation:
Hi. You didn't give the experiment and I searched online but couldn't find the experiment but through further researches, I got to know that the correct option is B "Although we did not measure this directly, it is possible that the same rate of change observed in the fossil record applies to modern population"

When people run quickly, they can sweat profusely. Their muscles undergo movement, and the loss of energy takes place. Based on this description, in which two ways is energy conserved when people run?
1. Heat energy is released from the body to the surroundings.
2. Heat energy is taken from the surroundings to the body.
3.Chemical energy is converted to mechanical energy that’s used for muscle movements.
4.Radiant energy is converted to mechanical energy that’s used for muscle movements.
5.Heat energy is converted to mechanical energy that’s used for muscle movements.
When we run, we sweat, which means we're getting hotter and hotter and our bodies need to cool down, which they do through transpiration (sweating). If we need to cool down, we need to release the heat that is in our bodies.
To run, we also need to move our muscles, which requires a specific type of energy, called mechanical or kinetic energy, which is the "energy of movement". In our bodies, we don't store that type of energy though, so we have to convert chemical energy to mechanical energy.
Answers:
⭕Heat energy is released from the body to the surroundings.
⭕Chemical energy is converted to mechanical energy that’s used for muscle movements.
Answer:
Heat energy is released from the body to the surroundings.
Chemical energy is converted to mechanical energy that’s used for muscle movements.
