Why do you think DNA is duplicated before
a cell divides? Why do you think the sister chromatids
are attached to one another?
The two cells that result from a single cell need to have the same amount of genetic material as the initial cell, therefore the DNA needs to be duplicated before the cell divides.
The sister chromatids are attached together so that during anaphase the daugther cells will receive the same chromosomes

Os anticolinesterásicos podem ser usados para antagonizar o efeito de um bloqueio do receptor nicotínico por curare, mas este procedimento requer o uso concomitante de atropina, um antagonista muscarínico. Qual a lógica deste procedimento? Resposta:
Answer:
To show effectiveness.
Explanation:
The logic of this procedure is to show the effectiveness of Anticholinesterase. Anticholinesterases are the drugs that prevent destruction of the neurotransmitter acetylcholine by the action of acetylcholinesterase enzyme within the nervous system. Anticholinesterases are very important drug due to their effectiveness that decrease breakdown of acetylcholine which is an important messenger of the nervous system so this procedure is very important to the effectiveness of Anticholinesterase drug.

Which process is included in the formation of both metamorphic and sedimentary rock?
A.
heating
B.
recrystallization
C.
compaction
D.
weathering
Answer:
C. compaction
Explanation:
The weight on the lower layers increases as the layers of sediment stack up. The soils are pressed together, squeezing out some water mixing in with the sediments. This approach is known as compaction.
The sedimentary series has formed into a sedimentary stone following compaction and cementation.

pls answer ASAP Plants have different signals for attracting pollinators. It is not uncommon for the same plant to have more than one signal. Which of the following would NOT be a way in which plants attract pollinators?
Answer:
I would say the answer would be A. barbs
Explanation:
C and D are the ones I know of but if the bright colored plants then maybe patterns would fall into that category so A would NOT be a way in which plants attract pollinators.
Plants have different signals for attracting pollinators, and it is not uncommon for the same plant to have more than one signal, these colors attract different pollinators for pollination purposes.
What is the significance and impact of pollination in ecosystems?Pollination helps maintain biodiversity and the balance of ecosystems; it is essential for the production of crops, fruits, vegetables, and nuts and has significant ecological, agricultural, and economic importance. Pollination is an important process that is provided by wild and managed pollinators in different ecosystems.
Hence, plants have different signals for attracting pollinators, and it is not uncommon for the same plant to have more than one signal, these colors attract different pollinators for pollination purposes.

As the moon revolves around Earth, it appears to change shape. The moon goes through phases during a period that lasts about one month. Describe what causes the moon to change shape as it goes from a full moon to a last-quarter moon.
Answer:
The correct answer is - the reflected light of sunlight changes as it moves around the earth.
Explanation:
The moon appears to change its shape during the revolving around the earth. This change in the shape of the moon takes place due to the fact that the moon does not have its own light and it reflects light from back to us on the earth.
The moon changes its shape on the basis of how much-reflected light or moon we can see and how much of the moon is facing the sun.
The correct answer is - the reflected light of sunlight changes as it moves around the earth.

Florida gets so much
more rain in the summer
months than in the
winter months?
Answer:
Air that is warmer is able to evaporate more water into the atmosphere. An air mass with more water vapor available to precipitate will naturally create more precipitation.
Explanation:
Most of South Florida has a tropical climate. There is a defined rainy season from May through October, when air mass thundershowers that build in the heat of the day drop heavy but brief summer rainfall. In some years the dry season becomes quite severe and water restrictions are imposed to conserve water.
Answer:
Summer is, as usual, the rainiest season because of thunderstorms, but also because of the contribution given by hurricanes, Also another reason is how close Florida is to the ocean and the humidity and heat when ever it's summer and hot out, so I believe that's why it rains the most in Summer than winter
Explanation:
What kind of events can occur to slow or restart ecological succession?
O wind, rain, and ice can cause ecological succession
the seasons make it start over every year
O nothing can restart it once it has begun
O fire, flood, farming, and ice ages can affect ecological succession
Answer:
O fire, flood, farming, and ice ages can affect ecological succession
Explanation:
Ecological succession is defined as the process in which ecology or environmental structure changes as the time passes.
Fire, flood, farming, and ice ages are some of the factors that can slow or restart secondary ecological succession because these factors can remove most vegetation and animals unable to flee the affected area.
Hence, the correct answer is "fire, flood, farming, and ice ages can affect ecological succession".

Enzymes ___________ the activation energy required for a chemical reaction which will ______ up the reaction process.
Enzymes reduce the activation energy required for a chemical reaction, which will increase the reaction process.
What are enzymes?Enzymes are bio-catalysts. They are made up of proteins that increase the speed of the reaction. They reduce the activation energy of the reaction.
Enzymes do not involve in the reaction and in the end of the reaction. They separate from the reaction and their substance is specific, they are specific to reactions whose speed is increased by these enzymes in high temperatures and pH.
Their structure changed as they are protein and with extreme where they also get the nature.
Therefore, Enzymes lower the activation energy required for a chemical reaction, which speeds up the reaction.

How does light
color affect the rate of photosynthesis
Answer:
Explanation:
Plants can absorb any color of light but how it is affected is dependent on the color. the reason this is because the chlorophyll in plants absorbs the light and transforms it into chemical energy. According to scientists if you were to shine purple light on the plant it would enhance the taste and color of the plant. If you were to use blue light it would increase the speed the plant grows at. if you use a yellow light it would decrease the speed that the plant grows at. In conclusion it depends on what color is used.

The Red and White earbuds will rise againMy beginning and end cannot return to the company the way it isThe Author and Financier coming to set the tableHis wife and legal consultant traveling for the holidays He is the Judge and executioner walking like a sergeantExplanation:
When two or more individual nouns or noun phrases are combined to form a single or longer noun phrase, it is called a compound subject. In other words, When more than one noun is put together to act as a single subject, it is said to behave as a compound subject. For example, "My son and partner will run this company when I travel out of the country". In the sentence above, the compound subject is "My son and partner".
Predicates on the other hand are parts of a sentence that contains the action words or phrases about a subject. For example, "The truck has been sold" . The part of the sentence that reads "has been sold" is the predicate. Whilst the subject is the Truck.
