Which theory suggests that aging is the result of unstable oxygen molecules that cause damage to the structure of cells with age
Answer:
Free radical theory of aging.
Explanation:
Free radical theory of aging suggests that aging is the result of unstable oxygen molecules that cause damage to the structure of cells with age because cells accumulate free radical damage overtime and free radical is an atom with unpaired electron in it's outermost shell. It is associated with oxidative damage.
the free radical theory is only concerned with free radicals such as superoxide ( O2− ), but it also comprises of oxidative damage from other reactive oxygen species such as hydrogen peroxide (H2O2), or peroxynitrite (OONO−).
Imagine yourself as a chocolate. Now write a travelogue on your journey through a digestive system mentioning all the organs and the processes happening in different parts.
Answer:
The process of digestion in the human body takes place over six (6) steps. This travel log would be documented with each chapter as a step:
Day 1: Ingestion. I do not know how I got into this dark wet room (mouth) with huge white grinders (teeth), but I do not believe I would make it out in one piece; these grinders keep mashing me up n what I believe to be 'chewing'.
Day 2: Propulsion. There's a tunnel (oesophagus). I feel like I'm going down a wet slide.
Day 3: Physical digestion. I think I'm in some sort of sac-like mechanism (stomach)with thick walls that produce some sort of toxic substance (acids and enzymes) to my body. This is where I die.
Day 4 and 5: Chemical digestion and absorption. There is almost nothing left of me; I am being taking in by the walls of this maze (small intestine). More of the 'toxic' substance is coming from what appears to be leaf (liver) and all my constituents are being disintegrated (by the duodenum). Now there's a larger maze (large intestine or colon). I'm being separated and completely absorbed. The things that aren't useful about me (waste/stool) are being sent away.
Day 6: Defecation. Waste is excreted in the nus through the rectum.
I hope this was helpful.

what is stomata plzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz give me the answer
Answer:
Actually i attended Bilology classes two decades ago. But i still remember that stomata is the outer lining of plants' leaves through which exchange of gas takes place with the surrounding environment.
Answer:
are tiny openings
Explanation:
Stomata are tiny openings or pores in plant tissue that allow for gas exchange. Stomata are typically found in plant leaves but can also be found in some stems. Specialized cells known as guard cells surround stomata and function to open and close stomatal pores. Stomata allow a plant to take in carbon dioxide, which is needed for photosynthesis. They also help to reduce water loss by closing when conditions are hot or dry. Stomata look like tiny mouths which open and close as they assist in transpiration.

The statement is a quantitative observation. Thus, option A is correct.
What is a quantitative observation?Quantitative perception is a technique for get-together and investigating information. It utilizes mathematical information and factual estimations to gauge examination and make determinations. It for the most part includes factors with a mathematical worth. One more type of quantitative perception is when scientists partner explicit factors with a number, such as rating their fulfillment on a size of one to ten. Ordinarily, scientists utilize quantitative information while exploring huge gatherings, since their outcomes might be more precise relying upon how enormous the gathering is.
It's generally normal for scientists to utilize quantitative information to all the more likely grasp the sentiments, wellbeing and ways of behaving of huge populaces of individuals. Normally, scientists direct face to face surveys, surveys and studies to accumulate their exploration, or they utilize online stages to control research.

This is one of the stages of Cell division in organism cells.it is marked with the the separation of homologous chromosomes into separate sister chromatids by the mitotic spindles.
other phases of cell division are -Interphase,Prophase, Metaphase,Anaphase and Telophase_ IPMAT
Based on mechanisms these sister chromatids are formed by the breaking down of the special protein : Cohesin which holds the sister chromatids together.As this protein is broken down, each chromatids moves to the opposite poles of the cells.
Generally there are two types of cell division,mitosis and meiosis. Anaphase it divided into 1 and 11 in meiosis, but made up of single phase in mitosis.
The separations of the identical chromatids into separate cells ensures that variation can occur,It also prevent fusion or non- disjunction of the chromosomes,which may lead to abnormalities.

The sympathetic preganglionic neuron cell bodies are housed in the _______ horn of the appropriate thoracolumbar regions of the spinal cord.
Answer:
The correct answer is "lateral horns of the T1L2 segments of the spinal cord".
Explanation:
The missing options of this question are:
A. anterior columns of the spinal cord.
B. posterior columns of the spinal cord.
C. sympathetic trunk.
D. lateral horns of the T1L2 segments of the spinal cord.
E. paravertebral ganglia.
The correct answer is option D. "lateral horns of the T1L2 segments of the spinal cord".
The cell bodies of the sympathetic preganglionic are located in the visceral efferent column of the spinal cord, which is also known as the lateral horns of the spinal cord. Since the cell bodies belong to preganglionic nerve fibers, they are always located close to the spinal cord. On the other hand, parasympathetic ganglia are often not located within the spinal cord, and act separate from the autonomic nervous system.

*30 points* Purebred tall pea plants look the same as tall, heterozygous pea plants. Formulate a pollination experiment to identify whether a tall pea plant is purebred or heterozygous
Test crosses are used to determine the genotype of an individual that expresses a dominant trait by crossing this individual which an homozygous recessive individual expressing the recessive trait. The pollination experiment could be a test cross.
What is a test cross?
Test crosses are experimental crosses carried out to determine the genotype of one of the involved individuals.
Test crosses include a homozygous recessive individual and another individual of an unknown genotype whose phenotype we already recognize.
The main goal is to know if the individual of the unknown genotype is a heterozygous or a homozygous dominant individual.
If it is heterozygous,
→ 50% of the progeny will be heterozygous and express the dominant phenotype,
→ 50% homozygous recessive expressing the recessive phenotype.
If it is homozygous, the whole progeny will be heterozygous and will express the dominant trait.
In the exposed example, we have two traits: tall and short.
We will assume a diallelic gene codes for this feature, and expresses complete dominance.
Dominant allele T codes for tallRecessive allele t codes for shortTo determine if tall plants are homozygous dominant or heterozygous we will separate them and produce controlled test crosses with short plants, which are homozygous recessive.
The test cross between homozygous recessive plants and homozygous dominant plants will only produce tall plants.

which will have the GREATEST impact on kinetic energy
Answer: the speed of the body
Explanation: kinetic energy is equal to the the half of the multiple of mass and speed so the increasing and decreasing of the speed has a greatest impact on the kinetic energy.
Add me as the brainleist please!!!!!!!!!!!!!!!!!!!!!!!!!!!!
The kinetic energy of a body depends on its mass and velocity but velocity has the greatest impact on kinetic energy.
What is kinetic energy?The energy that an object has as a result of motion is known as kinetic energy. It is described as the effort required to move a mass-determined body from rest to the indicated velocity. The SI unit of kinetic energy is the joule (J).
Radiant, thermal, acoustic, electrical, and mechanical kinetic energies are the basic categories. The capacity to perform work is kinetic energy's most significant quality. Kinetic energy can be increased by increasing mass and velocity and can be decreased by decreasing them.
Kinetic energy depends on both the mass and velocity of the body but it is most affected by velocity.

animal can be transferred to the next level of a food chain.
Answer:
don't understand your questions please send again
Some of the matter taken in by an animal can be transferred to the next level of food chain because some of the matter has been consumed by the animal organism for natural processes.
Food chain is a term that refers to the food relationship that involves several species of a biological community. The trophic chain is based on the transfer of nutritive substances in which each species feeds on a preceding species and so on.
A peculiarity of the food chain is that not all the material that an animal species ingests is transferred to the animal that feeds on it. This is because part of this material has already been consumed as energy for all the natural processes of the body, so only a small part is transferred to the next.
