Answer:
A. A resource that is so scarce (in restricted quantity) that it limits the size of a population is called a limiting factor. Any single resource can be a limiting factor to a population size. For example, the amount of water available can affect the number of plants that can grow in an area.

3. Si sales de tu casa y recorres 5 metros de distancia. ¿A qué distancia te
desplazaste?
Answer:
5 metros.
Explicación:
Si sale de su casa y camina 5 metros, significa que está a 5 metros de su casa porque cubre 5 metros de distancia. La distancia es la longitud que recorre un cuerpo entre dos puntos. Aquí un punto es la casa y el otro punto es la persona, por lo que si calculamos la longitud, encontramos que el individuo cubre 5 metros por lo que podemos concluir que el individuo está a 5 metros de su casa si camina 5 metros de su casa. casa al exterior.

Suppose that millions of years from now Australia moves to South America. Would Australia still have the same kinds of mammals? Explain your answer.
Answer:
Which best explains why Australia has life forms that do not exist anywhere else on Earth? Australia was separated from the other landmasses by geological forces. Scientists think that dolphins and whales may have evolved from a common ancestor.
Assuming that millions of years from now Australia moves to South America. Australia would not have the same types of mammals, because with the junction of the continents new conditions would suggest for animals to evolve.
What was the evolution of continents?Continental Drift is a theory that claims that, at one time, all the present-day continents formed just a single landmass, called Pangea. This supercontinent, thanks to the movement of the Tectonic Plates, fragmented several times until it provided the current shape of the land masses.
With this information, we can conclude that millions of years from now Australia will move to South America. Australia would not have the same types of mammals, as with the joining of the continents new conditions would suggest the evolution of animals.

Which do solar flares and coronal mass ejections have in common? Select the two correct responses.
A. They appear as dark spots on the sun's surface.
B. They tend to occur during minimum points in the solar cycle.
C. They are caused by the sun's changing magnetic field.
D. They are explosive events that can affect Earth.
C. They are caused by the sun's changing magnetic field.
D. They are explosive events that can affect Earth.
Explanation:
I'm sorry if it is wrong but I am almost 100% that it is correct!
Have a good one!
The solar flares and coronal mass ejections are caused by the sun's changing magnetic field. Also they are explosive events that can affect Earth. The correct options are C and D.
What is solar flare?A solar flare is a massive explosion on the Sun caused by the sudden release of energy stored in 'twisted' magnetic fields.
However, not all solar flares are safe. While the Earth's magnetic field protects us from solar radiation, the sheer electromagnetic power of a flare disrupts power grids, internet connections, and other communication devices.
Ejections occur at varying rates depending on the phase of the solar cycle, ranging from about 0.2 per day near the solar minimum to 3.5 per day near the solar maximum.
Coronal Mass Ejections are large plasma and magnetic field expulsions from the Sun's corona.
The sun's changing magnetic field causes solar flares and coronal mass ejections. They are also explosive events that can have an impact on Earth.
Thus, the correct options are C and D as per the given scenario.

During prophase I of meiosis, these pairs form a tetrad in a process called:
Answer:
Synapsis...
Hope that helps!
Explanation:
During prophase I of meiosis, these pairs form a tetrad in a process called crossing over or recombination. Tetrad is formed with the help of the alignment of two homologous chromosomes.
What do you mean by Meiosis?Meiosis may be defined as a process where a single cell divides twice to create four cells comprising half the original amount of genetic information.
In prophase I of meiosis, the two homologous chromosomes align in such a way that it undergoes crossing over, which synthesizes four chromatids of two chromosomes and leads to the formation of the tetrad.
Therefore, during prophase I of meiosis, these pairs form a tetrad in a process called crossing over or recombination.

Antibodies are found in the blood plasma.
True
False
Answer:
True
Explanation:
Blood plasma contains antibodies, a type of protein that can fight a substance considered foreign to the host body. The body manufactures antibodies to correspond to naturally occurring antigens inherited through DNA. Foreign antigens occasionally introduced by way of pregnancy or blood transfusions will also cause the body to make antibodies.

1. For a mutation to affect evolution, it must:
a. Provide a benefit to the organism
b. Involve more than one chromosome
c. Be able to get passed from parent or offspring
d. Be neutral—neither help nor harm the organism
For a mutation to affect evolution, it must provide a benefit to the organism. Hence option A is correct.
In order for a mutation to have an effect on an organism’s progeny, it must: occur in the next generation’s cells and affect the inherited material, impact the environment, and generate diversity among species.
They result in novel proteins that allow organisms to adapt to environmental changes. Mutations that are beneficial are necessary for evolution to take place. Mutations that enhance an organism’s ability to survive or reproduce are likely to increase in frequency over time.
