Where is energy stored in photosynthesis and cellular respiration?

Answers

Answer 1

Answer:

Chlorophyll is typically packed into stacks of membranes (called grana); it is in the grana where some of the sunlight is absorbed. Sunlight is converted to chemical energy in the form of ATP (adenosine triphosphate), which is the main energy-storing molecule in living organisms.

Students in a science class visited four local ecosystems. The students observed the species present in each ecosystem and recorded their observations in the table.


Based on these observations, which ecosystem is likely to be the least sustainable?

A.Ecosystem 1, because it has the fewest species
B.Ecosystem 2, because it includes both aquatic and terrestrial species
C.Ecosystem 3, because it has few predators
D.Ecosystem 4, because it supports many animals

Answers

the answer is A

this is because in ecosystem 1 there are only predators and no other species are observed. therefore predators have less food to eat thus they will die of hunger or move to another ecosystem

This is because in ecosystem 1 there are only predators and no other species are observed. therefore predators have less food to eat thus they will die of hunger or move to another ecosystem.

What is Ecosystem?

An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life.

Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. Biotic factors include plants, animals, and other organisms. Abiotic factors include rocks, temperature, and humidity.

Every factor in an ecosystem depends on every other factor, either directly or indirectly. A change in the temperature of an ecosystem will often affect what plants will grow there, for instance.

Describe what happens in your central nervous system when you prepare and eat breakfast. Start with objects in the environment and be specific.

Answers

Answer:

CNS controls eating by homeostatic mechanisms that interact  with different cognitive control systems (e.g., memory, reward, attention, etc)

Explanation:

In the brain, eating control is modulated by different systems:

1- Homeostatic control: the hypothalamus plays a key role by controlling both the appetite and food intake

2- Attention: the parietal and visual parietal cortices are involved in sensory perception and integration

3- Emotion and memory: amygdala and hippocampus

4-Cognitive control: the prefrontal cortex (i.e., executive functions)

5-Reward: associated with the functioning of the striatum

In the first place, external signals such as, for example, neurotransmitters and hormones, are received by the hypothalamus that interacts with different systems (reward, emotion, memory) in order to achieve a homeostatic control of eating. Neuronal stimulation (for example, when we view foods), is achieved by the supply of oxygenated hemoglobin.

5. Ventricular filling.

6. Ventricular ejection.

7. Isovolumetric contraction.

Explanation:

In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.

Generally, the cardiac cycle occurs in two (2) stages;

Diastole: in this stage, the ventricles is relaxed and would be filled with blood. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.

The following terms describe the physical or mecahnical events with the correct phases of the cardiac cycle in mammals (human beings).

1. Isovolumetric relaxation: All 4 cardiac valves are closed and all 4 chambers are relaxed during this phase.

2. Ventricular filling: The maximum amount of blood is in the ventricles at the end of this phase.

3. Isovolumetric contraction: The pressure in the ventricles is higher than in the atria, but lower than in the arteries, during this phase.

4. Ventricular ejection: The semilunar valves are open and the AV valves are closed during this phase.

5. Ventricular filling: The atria contract at the end of this phase.

6. Ventricular ejection: The pressure in the ventricles is higher than the pressure in both the atria and the arteries during this phase.

7. Isovolumetric contraction: Systole begins with this phase.

Explain why the steroid hormone estradiol (MW 272) readily crosses membranes by simple diffusion but the much smaller H requires transport proteins

Answers

Answer:

Estradiol has a higher partition coefficient than H+ ions

Explanation

Estradiol is a non-polar and hydrophobic molecule that has a higher partition coefficient than H+ ions, it means that the cell membrane is more permeable to this molecule because it can dissolve in and diffuse within the hydrophobic phase of the membrane. The movement of polar charged molecules (even small H+ ions) requires the input of energy to be able to dissolve within the lipid bilayer. In consequence, the movement of H+ ions requires proteins capable of transporting these protons through the membrane.

When a mutation alters a protein that plays a critical role in the body, it can disrupt normal development or cause a medical condition. A condition caused by mutations in one or more genes is called a genetic disorder. In some cases, gene mutations are so severe that they prevent an embryo from surviving until birth.Over time, a mutation might take place in one of the descendant cells, causing increased activity of a positive cell cycle regulator. The mutation might not cause cancer by itself either, but the offspring of this cell would divide even faster, creating a larger pool of cells in which a third mutation could take place.

Beyond the responsible development of rainforests, efforts to rehabilitate and restore degraded forest lands along with the establishment of protected areas are key to securing rainforests for the long-term benefits they can provide mankind.

Explanation:

i lloke dit up online because i have not did this yet

A very high damaged leads to no restoration of rainforest by secondary ecological succession.

A rainforest can reach a point when it cannot be restored by secondary ecological succession when the large portion of the rainforest is destroyed and most of diversity is vanished. At this time, restoration is impossible due to very high damages.

Ecological resilience is the ability of an ecosystem to be restored through secondary ecological succession after a severe disturbance. Rainforest have a high biodiversity that helps it to resist damage but at a certain limit so we can conclude that very high damaged leads to no restoration of rainforest by secondary ecological succession.

Based on the data in the graph, how are cyanobacteria responsible for the rise in atmospheric oxygen? State your claim, then make sure to use evidence from biological processes and data from the graph to support your claim.

Answers

Answer:

They perform photosynthesis, releasing oxygen into the atmosphere as a by-product.

Explanation:

Around the time that cyanobacteria appear around 3.2 billion years ago, the oxygen levels rise sharply.

Cyanobacteria are photosynthetic organisms. They possess the photosynthetic pigment chlorophyll, meaning they can trap light energy and use it to power chemical reactions to synthesise glucose. They convert carbon dioxide and water into sugar, releasing oxygen into the atmosphere as a byproduct. This causes oxygen levels to rise.

Answer:

Cyanobacteria are microbes that live primarily in seawater. They are believed to have been the first organisms on Earth to perform oxygenic photosynthesis. In this process, they produce organic carbon, the building blocks of life's molecules, and release oxygen gas (O2).As oxygen photosynthesis starts,that's when the first O2 producing of cyanobacteria occurs.The graph reaches a peak at Cambrian explosion.

A. They determine the amino acids in the proteins synthesized.
B. They prevent mutations from occurring in the process of DNA replication
C. They help complete the sugar-phosphate backbone of DNA molecules.
D. The amount of adenine and cytosine determines the length of the gene on a DNA molecule.

Answers

Answer:

A

Explanation:

Essentially, in the process of protein synthesis, there is first transcription where mRNA is synthesized off of a DNA strand with complementary nitrogenous bases. After processing occurs (in basic terms the mRNA is literally processed) and the mRNA strand leaves the nucleus, it attaches to a large and small ribosomal subunit (a ribosome) where translation occurs. The gist of it is when the mRNA strand is being read by the ribosome. tRNA will come over and bind temporarily bringing with it a specific amino acid, starting the formation of the polypeptide/amino acid chain. Nitrogenous bases play into this as the sequence of the nitrogenous bases is what determines what tRNA will bind onto it which determines which amino acid is brought. More specifically, this deals with the codons of the mRNA and the corresponding anticodons with the tRNA, which is a bit of a more specific topic.

The nitrogenous bases help complete the sugar-phosphate backbone of DNA molecules. The correct option is C.
