How are nucleus and chloroplasts different?
Answer:
Chloroplasts are organelles that conduct photosynthesis, where the photosynthetic pigment chlorophyll captures the energy from sunlight, converts it, and stores it in the energy-storage molecules ATP and NADPH while freeing oxygen from water in plant and algal cells. They then use the ATP and NADPH to make organic molecules from carbon dioxide in a process known as the Calvin cycle.

If a nerve cell stopped functioning, the cell would
F start producing oxygen.
G begin dividing into more cells.
H become a different type of cell.
J stop sending signals to the brain.
Answer:
J stop sending signals to the brain
Explanation:
If a nerve cell stopped functioning, the cell would stop sending signals to the brain. The correct option is J.
What are nerve cells?Nerve cells, also referred to as neurons, are 'excitatory' cells that can convert a variety of stimulation into electrical signals.
It usually aids in consistent sending information about the external as well as internal environment to the central nervous system in the form of action scenes of action potentials.
Neurons are the basic units of the nervous system, including the cells that receive sensory input from the outside world, send motor commands to our muscles, and transform and relay electrical signals at every phase between each one.
Thus, the correct option is J as any damage in the nerve cell can lead to impaired signaling to the brain.

How does inflammation contribute to the development of atherosclerosis?.
Answer:
Inflammation is associated with severity of disease, and complex lesions, which are prone to rupture and cause acute events, are characterized by extensive inflammation. Thus, inflammation is an active driver of atherosclerotic plaque development and a risk factor for atherosclerotic events.
Explanation:

have an awesome day -TJ
Inflammation is crucial in all stages of atherosclerosis. Stable plaques have a chronic inflammatory infiltrate, whereas vulnerable and ruptured plaques have a "active" inflammation that causes thinning of the fibrous cap, predisposing the plaque to rupture.
What is atherosclerosis?Atherosclerosis is a thickening or hardening of the arteries caused by plaque buildup in the artery's inner lining.
High cholesterol and triglyceride levels, high blood pressure, smoking, diabetes, obesity, physical activity, and consumption of saturated fats are all risk factors.
Atherosclerosis is a chronic inflammatory process in which both the innate and adaptive immune systems1 play important roles in its onset and progression.
The expression of the potent procoagulant tissue factor is increased by cross-talk between T lymphocytes and macrophages.
When the plaque ruptures, as shown here, the tissue factor induced by inflammatory signaling causes the thrombus that causes the majority of acute atherosclerosis complications.
Thus, this way the inflammation contribute to the development of atherosclerosis.

Written-Response Question #1
Guppies are small fish that live in South American rivers. They can have different-sized spots on their bodies. The river bottoms are covered in rocks. Guppies with spots that are the same size as the rocks on the bottom are harder for bigger fish to see and catch. The diagram above shows a population of guppies that lived in a river. Scientists had previously only seen guppies with medium or large spots in this river; they had never seen any guppies with any other spot sizes. The diagram below shows how the population changed after many generations.
• Karina says the change in the guppy population was caused by a mutation.
• Miles says the change was caused by a change in the environment.
• Zora thinks both Karina and Miles are correct.
Who do you think is right? Explain what happened to the guppies over many generations
The statement 'Karina says the change in the guppy population was caused by a mutation' is correct. Mutations change the frequency of phenotypic traits in a population across generations.
What is evolution?The word 'evolution' refers to descendence with modification which especially happens due to the process of natural selection.
The mutations in the genetic material serve as raw material for natural selection and consequently for evolution.
In this case, Karina must be right because the change in the frequency of the phenotype can be caused by the emergence of beneficial mutations in individuals that live in a given environment.
These types of mutations (beneficial mutations) can fix and increase their frequency across generations.

Answer:use aluminum as a substitute and recycle electronic waste
Explanation:
Recycling electric waste and using aluminum as a substitute are the two best solutions. Aluminium is a material that can be used to replace copper and thus reduce copper mine production.
What is Aluminium?Aluminium is a chemical element with the atomic number 13 and the symbol Al. Aluminium has a lower density than other common metals, about one-third that of steel. When exposed to air, it forms a protective layer of oxide on the surface due to its high affinity for oxygen. Aluminium is a silvery-white metal that is lightweight. It is pliable and malleable. Uses. Aluminium is used in a wide range of products such as cans, foils, kitchen utensils, window frames, beer kegs, and aircraft parts. This is due to its unique properties.
