Answer:
Prophase I
Explanation:
During prophase I, homologous chromosomes pair up and exchange sections of DNA.
During prophase I, the homologous chromosome pairs independently align themselves at the equator of the cell.
What happens in prophase I?DNA replication precedes the start of meiosis I. During prophase I, homologous chromosomes pair and form synapses, a step unique to meiosis. The paired chromosomes are called bivalents, and the formation of chiasmata caused by genetic recombination becomes apparent.
Moreover, during prophase I, the complex of DNA and protein known as chromatin condenses to form chromosomes. The pairs of replicated chromosomes are known as sister chromatids, and they remain joined at a central point called the centromere.
Therefore, during prophase, the chromosomes in a cell's nucleus condense to the point that they can be viewed using a light microscope. Prophase is the first phase of mitosis. During this phase, the chromosomes inside the cell's nucleus condense and form tight structures.

Will the entire starch molecule be able to enter the cells of the digestive tract?
Particularly important dietary carbohydrates include starch and disaccharides such as lactose and sucrose. None of these molecules can be absorbed for the simple reason that they cannot cross cell membranes unaided and, unlike the situation for monosaccharides, there are no transporters to carry them across.
Write a paragraph to justify Earth’s past Plate movements by explaining three pieces of evidence presented in the article. Highlight each of the three pieces of evidence.
Fossils, galciers and complementary coastlines are the evidences of earth's past plate movements.
How justify Earth’s past Plate movements?Modern continents hold clues to show their past events such as fossils, glaciers, and complementary coastlines. These evidences help in revealing about the plates that once fit together. Fossils tell us when and where plants and animals once existed.
So we can conclude that fossils, galciers and complementary coastlines are the evidences of earth's past plate movements.

Biologists tell us that life on earth took billions of years to evolve into astronomy students and other examples of intelligent life. If we want to search for planets with intelligent life-forms that evolved over the same period of time that we did, what sorts of stars should we not bother searching around?.
The types of stars that we should not search for life around the Universe are O and B type stars.
What is a star?A star is a celestial body capable of producing huge amounts of heat and radiation in the form of light.
An O-type star (spectral class O) is a blue and/or white star that is characterized to be very hot and brilliant.
B-type stars are also luminous and they can be blue, but they can be differentiated by O-type stars by their spectra.

In what ways do viruses differ from other pathogens?.
Viruses differ from other pathogens because they are considered non-living.
What are viruses?Viruses are organisms that are incapable of reproducing on their own without a living host.
Viruses cannot undergo any of the characteristics of life outside a living host.
They, therefore, infect their host and use the mechanisms of the host to replicate themselves.
Therefore, viruses differ from other pathogens because they are considered non-living.

in an ecosystem which would have a bigger population: producers or primary consumers
PLEASE HELP
Answer:
The answer would-be producers. The fact that there are primary consumers today, you would know that producers make up the bigger population. If it were smaller, the primary consumers would have eaten them all up and eventually would die out because they would have no more food source. This would be bad for all higher-level consumers.

How to determine the chemical reaction of cellular respiration?
Answer:
C6 H12 O6+6O2-----6CO2+6H2O+ ATP
Chemical reactions of cellular respiration may be determined by where the respiration process undergoes. This is because cellular respiration may be of two types aerobic (in mitochondria), and anaerobic (in yeast and muscle cells).
What do you mean by Cellular respiration?Cellular respiration may be defined as the strategy by which living organisms incorporate oxygen with glucose molecules, and discard as waste products, carbon dioxide, and water, apart from energy.
The general chemical reaction of the cellular respiration may be determined as :
[tex]C_6H_1_2O_6 +[/tex][tex]0_2[/tex] → [tex]CO_2 + H_2O +[/tex] ATP. (Aerobic cellular respiration).
Glucose → Pyruvate → Lactate + ATP (Anaerobic cellular respiration).
Therefore, chemical reactions of cellular respiration may be determined by where the respiration process undergoes.

your friend argues that there is no need for scientific names for organisms and that the existence of both scientific and common names will only confise people. Explain why we have both
Answer:
Scientists and researchers need to have a "universal language", so they can communicate with others around the world. They use scientific names that normally have Latin origins.
The reason we use common names is so people don't get confused. Normal people won't go around saying they need to walk their canis lupus familiaris. They'd say they need to walk their dog.
Explanation:
Answer:
false
Explanation:
without the scientific name we would not be able to identify living and non living things
If the following events are arranged in the order in which they occur for an animal hiding and holding still in response to seeing a predator, which is the fourth event in the series?.
Animal hiding-holding still response follows the reflex arc sequence. The fourth event in the series is option B) signaling by efferent PNS neurons.
When the animal receives the stimuli, it responds to them. In the case of hiding-holding still response, the animal might freeze due to motor inhibition that reduces excitatory signals.
The reception and reaction to stimuli follows the reflex arc sequence.
What is reflex arc?The reflex arc refers to the sequence of events since the body receives an external stimulus until it reacts.
The correct answer is B) signaling by an efferent PNS neurons.
