This organelle uses light energy to make sugar from carbon dioxide and water are
Answer: Chloroplast
Explanation:
Plants and some algae have chloroplasts responsible for photosynthesis. Plants undergo photosynthesis to transform light energy into chemical energy. This energy is stored in the form of sugar to support their growth and provide energy. Chloroplasts have a double membrane, with the thylakoid membrane located within the inner membrane.
Photosynthesis occurs within the thylakoid membrane, which is folded into sacs called thylakoids. Chlorophyll, a green pigment, is present in the thylakoids and it absorbs light energy to split water molecules into hydrogen and oxygen. The oxygen is released into the atmosphere while the hydrogen is used to create ATP, a molecule that stores energy. ATP and hydrogen are then utilized to make sugar, the final product of photosynthesis.

What is CRISPR?
Thousands of genes that can lead to illness disorders in our bodies have been found by researchers.
Small guide RNA first forms a complex with the protein CAS9 endonuclease. The Cas9/sgRNA complex that results from this binds the PAM sequence found in the target DNA. Cas9 unzips DNA upon interacting with the PAM sequence.
Therefore, the small guide RNA (sgRNA) in the CAS9 complex combines with the target DNA to form a hybrid. Cas9, which snips the target DNA, detects this hybridization.

Cerebrospinal fluid flows from the fourth ventricle into the subarachnoid space surrounding the brain and spinal cord. From this space it drains through the arachnoid villi into the dural sinuses
Cerebrospinal fluid (CSF) is a clear, colorless liquid that circulates throughout the brain and spinal cord, providing a cushion for these structures and transporting nutrients and waste products. It is produced in the ventricles of the brain and flows from the fourth ventricle into the subarachnoid space, which is the space surrounding the brain and spinal cord.
From there, it circulates through the central nervous system and eventually drains through the arachnoid granulations, which are small projections that protrude into the venous sinuses of the brain. This allows CSF to enter the bloodstream and be eliminated from the body.

Which one of the following is caused by the secretion of atrial natriuretic hormone by the heart?
A) decrease in blood pressure
B) increased production of fats and proteins
C) decrease in kidney function
D) increase of blood sugar level
E) decrease in blood calcium level
The correct answer is A) decrease in blood pressure. Atrial natriuretic hormone is a hormone secreted by the heart that helps to regulate blood pressure and fluid balance in the body. When the heart detects an increase in blood pressure, it secretes atrial natriuretic hormone, which causes the kidneys to excrete more sodium and water, leading to a decrease in blood volume and ultimately a decrease in blood pressure. Atrial natriuretic hormone does not affect the production of fats and proteins, kidney function, blood sugar level, or blood calcium level.

explain the relation between cells, tissues, organs and organ systems in a human body in brief
Hi :)
Answer:
The body has levels of organization that build on each other. Cells make up tissues, tissues make up organs, and organs make up organ systems. The function of an organ system depends on the integrated activity of its organs. The survival of the organism depends on the integrated activity of all the organ systems, often coordinated by the endocrine and nervous systems.
Explanation:
In the human body, cells are the basic units of life. Groups of cells working together for a specific function form tissues. Organs are two or more tissues operating together. Even separate organs work together, forming body systems.
Hope this helps :) !!!
Cells form tissues, tissues combine to form organs, and organs work together to create organ systems, collectively maintaining the overall functioning of the human body.
Inside the human body, cells are the fundamental building blocks of life. They're arranged to form tissues. Organs are structures composed of different types of tissue, which perform certain functions. These organs are formed by the combination of tissues.
Organs, in turn, work together to create organ systems. Organ systems are groups of organs that work together in order to perform more extensive functions that allow a body to survive and function properly.

Lana is investigating what happens when people exercise strenuously. the common responses she got from regular runners in her residential area was that whenever they experience muscle pains for a while after strenuous exercise. based on the course lectures on cellular respiration explain which of the stages of cellular respiration these runners rely on when they are exercising strenuously, and what stages of respiration do not take place until they slow down or stop the exercise entirely. your response must be at least one paragraph long.
When people exercise strenuously, their muscles rely primarily on anaerobic respiration for energy production due to the increased demand for energy that cannot be met solely by aerobic respiration. Anaerobic respiration, specifically lactic acid fermentation, occurs in the cytoplasm of the muscle cells and does not require oxygen. This process produces lactic acid as a byproduct, which can cause muscle pains experienced by the runners after strenuous exercise.
When the runners slow down or stop exercising, their bodies can transition back to aerobic respiration, which takes place in the mitochondria and requires oxygen. Aerobic respiration is more efficient in producing energy (in the form of ATP) and does not produce lactic acid as a byproduct. Thus, during periods of rest or reduced intensity exercise, the muscle cells rely on aerobic respiration for their energy needs, and the lactic acid can be cleared from the muscles, reducing the pain experienced by the runners.

Proton-beam therapy is a type of radiation therapy used to treat cancer. In this therapy, a high-energy beam of protons is directed at a tumor. The protons have a specific range in tissue, and they stop inside the tumor, delivering most of their energy at the tumor site.
The main advantage of proton-beam therapy over traditional radiation therapy is that it can deliver a high dose of radiation to the tumor while minimizing damage to the surrounding healthy tissues. This is because protons have a unique physical property called the Bragg peak, which allows them to deposit their maximum energy at a specific depth within the tissue.
When the high-energy protons stop in the tumor, their kinetic energy is transferred to the tumor cells. This energy breaks apart the tumor's DNA, which is responsible for the cells' ability to grow and divide. By damaging the DNA, the tumor cells are unable to replicate and eventually die.
It is important to note that proton-beam therapy is a complex and specialized treatment that requires careful planning and precise delivery. It is typically used for tumors located near critical structures, such as the brain or spinal cord, where minimizing damage to surrounding tissues is crucial.
In summary, proton-beam therapy uses high-energy protons to deliver radiation to tumors, damaging their DNA and killing the tumor cells. This treatment offers the advantage of delivering a focused dose of radiation while minimizing harm to healthy tissues.
