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.

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.
Which results from the interaction of solar weather on Earth's magnetic field? Select the two correct answers.
A. geomagnetic storms
B. auroras
C. radiation belts
D. solar wind
Answer:
A & C
Explanation:
In short terms, A & C are the only answers that have anything to do with the magnetic field. Solar wind is part of solar weather, and is involved in the creation of the other three answers. Auroras are formed through the interaction of solar wind and the oxygen & nitrogen in Earth's atmosphere.
The geomagnetic storms and auroras are the results from the interaction of solar weather on Earth's magnetic field. The correct options are A and B.
What are solar weathers?Solar or space weather refers to actions that take place on the Sun's surface.
These reactions usually have different effects on our planet, owing primarily to the Earth's magnetic field, which acts as a shield for the planet.
A geomagnetic storm happens when the solar radiation collides with the Earth's electromagnetic field, causing disruptions in the magnetosphere.
The interaction of loaded solar particles and the land based electromagnetic field produces an aurora, which is a luminescent formation.
The solar wind transports these particles to the terrestrial electromagnetic field, in which they are shown in various colors depending on the type of particle.
Thus, the correct options are A and B.

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.

What is significant drawback to transferring electricity produced by solar where sunshine is abundant to states where it is not
Answer:
The transfer could only occur during the day because it cannot store solar energy.
Explanation:
The transfer of electricity produced from solar energy only occurs during the day because it cannot store solar energy at a tremendous level. At homes, we can easily store the electricity made from solar energy with the help of batteries but for providing electricity to a state where thousands of houses are present, enormous batteries are needed to store it which can't be made because of very high cost so that's why the solar energy can not be stored.

Two species of sea urchins adapted to live side by side on the sandy bottom of the sea floor. The two species appear to have the same diet—drift seaweeds and other bits of organic matter. They are able to adapt and to live in the same environment without competing with each other. How are they able to share habitat and food resources?
Two species of sea urchins live practically side-by-side in sandy bottoms. The two species appear to have the same diet: drift seaweeds and other bits of organic matter. They can live in the same environment without competing.
As it compels them to live in the same environmental surroundings so the characteristics of living nature also get developed as their current following situation that's helping them to get the same food & habitat.
Both species of sea urchins share the same habitat and food resources by separating their niches a little bit differently from one another.
What do you mean by Habitat?Habitat may be defined as a type of native environment for which a particular species is best adapted due to natural selection.
Competitive exclusion leads to the elimination of any one species until they do not share different niches.
Therefore, both species of sea urchins share the same habitat and food resources by separating their niches a little bit differently from one another.

What is a cell?
The smallest unit of life is a cell. There are biomolecules in it. Every living thing is composed of several cell units. Different sorts of creatures contain various types of cells.
Prokaryotic cells are the most basic types of cells; they are only seen in unicellular organisms, do not engage in cell division, and lack real cell organelles and a nucleus, instead having DNA coiling up in the cytoplasm.
Eukaryotic cells are higher cells that contain cell organelles and have the capacity to carry out a variety of intricate tasks required by big organisms.
Thus, Cell signaling is a method of communication between or within cells, and a change in a cell's activity is conveyed as a signal that may set off a chain of events so that the body can respond appropriately.
