How do plants get the energy they need to survive
Answer:
Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.

Explain how cells obtain energy from biological molecules in order to power cellular functions. Your answer should include a description of the structures and events of glycolysis, pyruvate oxidation, the Krebs cycle, and oxidative phosphorylation via the ETC and ATP synthase.
Answer:
oxidativa a través de la ETC y la ATP sintasa.
Explanation:
Cells obtain energy from biological molecules in order to power cellular functions as follows:
Adenosine triphosphate (ATP) is the biological molecule found in all living beings and constitutes the main source of energy that can be used by cells for various vital processes.
ATP can be produced from ADP and Pi (inorganic phosphorus) present in the medium, mainly through oxidative phosphorylation in mitochondria.
In aerobic organisms, the Krebs cycle is part of the catabolic pathway that performs the oxidation of carbohydrates, fatty acids and amino acids to produce CO2 and water, releasing energy in usable form (reducing power and ATP).The Krebs cycle uses acetyl-CoA that is formed by oxidative decarboxylation of pyruvate, by the action of the pyruvate dehydrogenase enzyme complex.
On the other hand, there are phosphate donor substrates that are used to synthesize ATP, a mechanism known as ATP synthesis at phosphorylation at the substrate level, such as what occurs in glycolysis or fermentation.
Glucose as the primary substrate in most cells is decomposed into CO2 through the oxidative process known as cellular respiration, where 38 molecules of ATP can be produced from a single glucose molecule.In the process of oxidative phosphorylation, the passage of electrons from NADH and FADH2 through the electron transport chain produces a pumping of protons or (H3O +) from the mitochondrial matrix into the intermembrane space.The flow of protons from the intermembrane space to the matrix provides part of the force necessary for the synthesis of ATP from ADP and Pi by ATP synthase.Most of the ATP synthesized in the mitochondria will be used for cellular processes in the cytosol, so it must be exported.Therefore, we can conclude that ATP provides the necessary energy to cells in order to power cellular functions.

Organisms that live in freshwater and marine biomes have developed unique adaptations that aid in their survival. Which of the following adaptations would be more useful for an animal in a marine biome than for an animal in a freshwater biome? a. flippers and flattened tails b. smooth, nearly furless body c. streamlined body d. tolerance to high levels of salinity Please select the best answer from the choices provided A B C D
Answer:
I think it is D.
Explanation:
The reason I think this is salinity is how salty the water is and an animal that can tolerate high levels of salinity will thrive well in marine biomes.
The adaptation that would be more useful for an animal in a marine biome than for an animal in a freshwater biome would be tolerance to high levels of salinity.
Marine biomes are characterized by a high level of salinity. The saline environments are often hypertonic to the cells of organisms. Thus, organisms will ordinarily lose water to such environments and die as a result of dehydration.
Hence, organisms that will successfully inhabit marine biomes must find a way to tolerate the hypertonic environment. One of such adaptations is the possession of salt glands in the body.

a) 0%
b) 75%
c) 25%
d) 50%
Answer:
25%
Explanation:
Tt x Tt is the cross you should start with because both are heterozygous. Make a Punnett square. The short phenotype (genotype tt) should show up only once out of the four total genotypes. 1/4=25%
Hi! Thanks for asking your question here on Brainly!

When an electrical current is passed through a gel, the DNA is repelled by the nearby positive current and pushed across the gel towards the negatively charged side. DNA has no charge. When a current is passed through a gel, the DNA is repelled by the negative current and pushed across the gel towards the positively charged side.
Answer:
DNA is negatively charged. When an electrical current is passed through a gel, the DNA is repelled by the nearby negative current and pushed across the gel towards the positively charged side.
Explanation:
Electrophoresis has become a standard molecular biology technique. This technique is based on the use of a constant-uniform electric field that enables the separation and identification of DNA fragments with different lengths, which form bands in the electrophoresis gel. Electrophoresis can be used to analyze not only DNA, but also RNA and proteins. During electrophoresis, the fragments of DNA that are negatively charged will migrate towards the positively charged electrode, where the duration of this movement will depend on the size of the DNA fragment, as well as of the pore size in the gel.

Which of these organisms are in a trophic level that receives a larger percentage of the energy captured by the producers than the percentage received at the bats’ trophic level?
Mountain lions
Ground squirrels
Snakes
Hawks
Answer:
D. Ground squirrels
Explanation:
Took the test
Ground squirrels are at a trophic level that receives a larger percentage of the energy they consume as producers than the percentage received at the trophic level of bats. So, the correct option is B.
What is Trophic level?The trophic level of an organism is defined as the position it occupies in a food web where a food chain is a succession of organisms that eat other organisms and are themselves eaten. An organism's trophic level is the number of steps from the beginning of the chain.
Organisms at the lower trophic level have the highest percentage of energy compared to those at the higher trophic level that have the lowest percentage of energy. For the example above, if a ground squirrel has 100% energy, the next trophic level will receive 10% of the total energy from a lower trophic level that only has 10%, other higher trophic levels only receive 1%, then the next level Only 0.1%
Therefore, the correct option is B.

. Jack and Jill are thinking about starting a family and they come to you with a question about a rare recessive genetic disease called Alpers Syndrome. Alpers causes progressive neurodegeneration in infants and children and is usually lethal within the first 10 years of life. Jack's grandfather had a brother die of Alpers Syndrome, while Jill has no family history of the disease. If the frequency of heterozygotes for Alpers is 1 in 2000 in the general population, what is the chance that Jack and Jill will have a child with Alpers Syndrome? (Be sure to completely reduce your answer.)
Answer:
The chance of having a Child who is a Heterozygote is 50% , The chance of having a child that will completely come down with Alpers syndrome is 0%
Explanation:
Jack has a history of Alpers in his family
Jill has no history
lets assume Jack is a carrier : Ab ( because that is how he could have survived the first 10 lethal years )
Jill : AA
Therefore the probability/chance of Jack and Jill having a child with Alpers ( carrier ) syndrome will be 50 % as shown below
AA * Ab = AA , Ab, AA, Ab
The child produced by Jack and Jill will only be a carrier of the syndrome and not completely affected by the syndrome
A meteorologist observes a decrease in barometric pressure and predicts a chance of light to moderate precipitation. Which frontal system
is most likely approaching?
Answer:
Warm front
Explanation:
A warm front is the transition zone of the replacement of a cold air mass by a warm air mass. The pressure centers of warm fronts are usually low and the pressure read by a barometer will decrease due to an incoming warm front
The general direction of motion of warm fronts is from southwest to northeast with warmer and moist air behind the warm front than air into which the front flows. Therefore, warm fronts normally results in moderate precipitation or rainfall or snow.
The frontal system that is most likely approaching is a WARM FRONT.
A warm front occurs when a warm air mass moves over a cooler air mass.The cooler air mass is denser, thereby remaining close to the ground.A warm front is generally associated with low pressure centers.The low pressure centers show lower pressure at the center compared to the outside. As the air rises, water vapor within condenses into water droplets, thereby forming clouds and thus also precipitations.In conclusion, the frontal system that is most likely approaching is a WARM FRONT.
