Explanation:
El agua (H2O) es una molécula clave que forma parte de los ecosistemas naturales y cuya presencia es crítica para el sostenimiento y la reproducción de la vida en la Tierra, ya que solamente este compuesto permite llevar a cabo procesos biológicos y reacciones químicas que hacen posible la vida. El agua es el principal componente del cuerpo en todos los seres vivos, representando el 65% del cuerpo en el hombre, 95% en una medusa, 90% en un hongo o 90-95% en la mayoría de las plantas. De este modo, el agua es imprecindible para la vida tal y como la conocemos. Además, el agua es un componente abundante en los ecosistemas naturales y alrededor del 70% del planeta está cubierto por agua, siendo este un ambiente propicio para el sostenimiento de la vida de una gran parte de los organismos que habitan la Tierra. Finalmente, el agua es una molécula polar que constituye un poderoso disolvente en estado líquido para diferentes sustancias tales como, por ejemplo, ácidos, álcalis, azúcares y gases incluyendo el oxígeno (O2) y el dióxido de carbono (CO2).
Scientist claims that Elysia chlorotica, a species of Sea slug, is capable of photosynthesis. which of the following observations provides the best evidence to support the claim?
A) Elysia chlorotica will die if not exposed to light
B) Elysia Chlorotica grows when exposed to light in the absence of other food sources
C) Elysia chlorotica grows faster when exposed to light than when placed in the dark
D) Elysia chlorotica grows in the dark when food sources are available.
Answer:
The correct answer is - B) Elysia Chlorotica grows when exposed to light in the absence of other food sources
Explanation:
If placing Elysia Chlorotica in presence of the food sources in the presence or absence of light it still grows as normal. However, if placing in the light in absence of the food sources it should not grow if it is not able to perform photosynthesis but it does which means there is a photosynthesis process also involve in the Elysia.
Photosynthesis is the process that involves the production of energy and nutrition in presence of light with water and atmospheric carbon dioxide.
Elysia chlorotica is a mollusc that belongs to the species of green slugs. It is generally found in the coastal zones of the United States including New Jersey, New York, Texas and Florida.
The correct answer is:
Option B) Elysia Chlorotica grows when exposed to light in the absence of other food sources.
The explanation for the option is:
Some of the chloroplasts are stored in the digestive system, which sustains and keeps them alive for months for later use.After some years these chloroplasts get deeply buried in the cells of the gut facilitating the slugs to remain green without feeding further.This merger of mitochondria into the cells enables the slugs to capture the energy and allows them to make their food just like plant makes food from the process of photosynthesis.Therefore, Elysia Chlorotica grows when exposed to light in the absence of other food sources as it makes its own food and energy.

What usually happenstance an ecosystem after a sudden catastrophic change?
Please help
Answer:
Succession occurs after sudden catastrophic change.
Explanation:
In communities, organisms occupy specific niches. These gradually evolve over time as these organisms interact with their geosphere. In ecological succession, a community may undergo several dynamic changes. These include primary succession and secondary succession- these communities eventually try to achieve equilibrium over time.
After catastrophic events, the microorganisms, primary succession occurs. Here, a colonizing species exploits a non-habitable region. These eventually make the region more habitable through nutrient cycling, weathering, etc. which ushers in secondary succession. Here, the communities become more complex with time, becoming more varied and an increasingly large food web.

DNA is considered the blueprint of life, yet in eukaryotic organisms, such as humans, DNA never leaves the nucleus. Which of the following is the best explanation for how DNA codes into physical traits and characteristics, even though it never enters the cytoplasm?
Answer:
The first one
Explanation:
This is just Central Dogma. DNA (deoxyribonucleic acid) is transcripted into mRNA which goes to the Ribosomes where it is turned into polypeptides/protiens which code the body.
DNA is a molecule made up of Deoxyribonucleic acid that is composed of two chains that coils are around themselves and form the double helix.
Within eukaryotic cells, DNA is organized into a strong structure called as chromosomes. These are duplicated in the cell formation process. Most organisms store their DNA in the cell nucleus. DNA is a long polymer made of repeating units. DNA is capable of coiling into tight loops and other shapes. As the genetic information is held within genes the genome encodes protein. Thus the DNA is a nucleus and can be transcribed in the mRNA which later eaves the nucleus and forms proteins. Hence the option A is correct.Learn more about the DNA is considered the blueprint of life yet in eukaryotic organisms.

Bananas (and other fruits) change as they ripen.
What happens to the carbohydrate molecules in the fruit as they ripen?
1. Use the tests to identify how the 2 different carbohydrate molecules change in the banana from unripe to ripe. (You will need to run both the Carbohydrates tests - One that tests for glucose and one that tests for starch for BOTH the unripe banana AND the ripe banana and record the results below).
2. Based on how you like your fruit (ripe or unripe), make a claim about how each of the different molecules tastes (sweet or unsweet-- think about which carbohydrate tastes more sweet starch or glucose?).
HELPPPPPPPPPP
Answer:
What happens to the carbohydrate molecules in the fruit as they ripen?
During ripening, there is an increase in the breakdown of starch inside the fruit, and a corresponding increase in the amount of simple sugars which taste sweet, such as sucrose, glucose, and fructose. This process is particularly obvious in bananas as they ripen. Green bananas do not taste sweet at all, and the riper they get, the sweeter they taste. There is also a decrease in acidity as the fruit ripens and a decrease in bitter plant substances, such as alkaloids. Last, as fruits ripen they produce complex compounds that are released into the surrounding air, giving a ripe fruit its pleasant aroma.
The breakdown of complex carbohydrates in the fruits increases in the fruits as they ripen.
What happens to ripened fruits?When fruits are growing on the plants, the plant is constantly providing them with water and nutrients for their development. Initially, the growing fruits are protecting the seeds inside them.
In the growing stage, fruits are not edible and do not attract predators. This allows the fruit and the seed inside it to develop properly.
After completion of seed development and the growth of fruit, it changes in appearance to attract consumers including birds, humans and animals.
The fruit also starts to get softer as the cell wall begins to break down. The cell wall is made up of complex carbohydrates with glucose as its monomer.
The cell wall is broken down by the protein enzymes that accompany the fruits as they ripen.
Therefore, the breakdown of complex carbohydrates in the fruits increases as they ripen.

Describe how the available energy in the marine ecosystem of the pacific northwest could be different than that of the african savanna
The available energy in the African savanna is Higher than the available energy in the Marine ecosystem
The African savanna is located closer to the Equator and maintains a temperature of around 20 to 30° C due to the availability of enough sunlight reaching the soil and the vegetation found in the African savanna. also there is enough rainfall all year round.
The availability of sunlight and rainfall year round makes the energy levels in the African savanna higher than the energy available in Marine ecosystem.
The Marine ecosystem which consists of Freshwater water and salt water bodies have less sunlight penetrating through them and this negatively affects the available energy ( chemical / heat ) present in the marine ecosystem.
Hence we can conclude that The available energy in the African savanna is Higher than the available energy in the Marine ecosystem.

What is the open area where an enzyme attaches called?
Answer:
The open area where the substrate is attached to an enzyme is called the active site.
Explanation:
The active site of an enzyme corresponds to the place where the tertiary structure of this molecule leaves a free space to couple the substrate and be able to catalyze a chemical reaction.
Since the enzyme-substrate complex functions as a key lock system, the active site has a three-dimensional configuration that only admits certain molecules as substrate, which determines its specificity.
