Why do we cook our food and put lime on fish / shrimp to make ceviche
Answer:
The reason is because ceviche (sev-ee-chay) is still very much raw fish or seafood.
The citrus bath the seafood sits in does turn the meat opaque, giving it the appearance of being cooked, and it does kill some of the many wee beasties present in raw foods that can make you sick, notably the toxin vibrio.

A. on the surface of the earth
B. in the oceans
C. deep beneath the earth’s surface
D. at the bottom of shallow lakes and rivers
Answer:
C

What is parasitic mode of nutrition? Explain with examples.
Answer:
Explanation:
ANSWER 1) Parasitic nutrition is a mode of heterotrophic nutrition where a parasitic organism lives on the body surface or inside the body of another type of organism (a host)
Examples of parasitic mode of nutrition are mosquito, ticks, lice, bedbugs , tapeworm
because lives on the body surface or inside the body of other organism called host.
ANSWER 2 ) Organisms that live in or on other organisms and acquire food at the expense of its host are called parasites. Most parasites are harmful to the hosts’ health; sometimes, they even kill the host. Both animals and plants may serve as a host. Unlike commensalism, the parasite causes some harm to its host. A few examples of parasites are louse on a human head, Cuscuta plant and tapeworms.
Cymothoa exigua is an unusual parasite. It is also known as the tongue-eating louse and is aptly named so as it is found in the mouth of the marine fish Lithognathus. It essentially severs the fish’s tongue, cutting off the blood supply and causing the tongue to fall off. The louse then attaches itself to the remains of the tongue and essentially acts as the fish’s new tongue.

Scientific investigations often lead to the formulation of new scientific questions. The observations Charles Darwin's
work after he returned home from his voyage and studying the selective breeding of pigeons prompted him to ask
which question?
Do living things change over time, and if so, how?
Are the Galapagos finches and those on the mainland the same species?
Are pigeons related to the Galapagos finches?
Can selection in nature also lead to a new species over time?
Answer:
D) Can selection in nature also lead to a new species over time?
Explanation:
The question will be "Can selection in nature also lead to a new species over time?". The correct option is D.
Who was Charles Darwin?English naturalist, geologist, and biologist Charles Robert Darwin is well-known for his contributions to evolutionary biology.
Charles Darwin, a naturalist of the 19th century, investigated the theory of natural selection.
Natural selection provides an explanation for how a species' genetic features might evolve through time. This could result in speciation, or the creation of a new, separate species.
New scientific questions are frequently posed as a result of scientific research.
After his journey, Charles Darwin studied the selective breeding of pigeons and made observations that led him to wonder: "Can selection in nature also lead to a new species over time?"
Thus, the correct option is D.

Among the listed components, the brain and the eye are the organs. Skeletal muscles are also classified as organs.
What are the levels of the organization?In anatomical studies of an individual, the classification of the hierarchy of the structures of the organism is useful for the estimation of the complexity level of the individual.
The chemical level of organization is the first level of organization where atoms are combined for the formation of molecules. Molecules are combined to form macromolecules.
Different types of macromolecules result in the cellular level of organization. The macromolecules that are the components of cells are called biomolecules.
Cells of the same kind are combined and work in the association as a tissue, for example, nerve cells form nerve tissue.
These tissues of similar functions combine to form organs. For example, multiple nerve tissues are combined to form the brain and the spinal cord.
The nerve cells, nerve tissues, spinal cord, and brain are studied together as an organ system called the nervous system. Several organ systems like this are grouped to form an individual.
Therefore, the brain and eye are examples of organs.

Answer: (v) of an object is equal to its final velocity (v) plus initial velocity (u), divided by two. Where: ¯v = average velocity. v = final velocity.
Explanation:
The average velocity of an object is its total displacement divided by the total time taken. In other words, it is the rate at which an object changes its position from one place to another.
What is a rule for making a neutral atom which has no charge?
The rule for making a neutral atom that has no charge is - Electron (E) = Proton (Protons).
Neutral atoms are atoms that have no charge or zero charges. It is known that an atom has three sub-atomic particles; Proton, Neutron, and electrons. Protons have a positive charge, neutrons have zero or no charges and electrons have negative charges.
There are three conditions possible:
The neutral atom that has no charge - The number of electrons and protons must be the same.E = P
A positive ion that has a positive charge - The number of protons has to be more than the number of electrons.E < P
A negative ion that has a negative charge - The number of electrons has to be more than the number of protons.E > P
Thus, the correct answer is - Electron (E) = Proton (Protons).

This usually happens when there is not enough oxygen in the body, so lactic acid fermentation provides a way to get ATP without it.

What is lactic acidosis?Lactic acidosis refers to lactic acid build up in the bloodstream. Lactic acid is produced when oxygen levels become low in cells within the areas of the body where metabolism takes place.
The symptoms of lactic acidosis include abdominal or stomach discomfort, decreased appetite, diarrhea, fast, shallow breathing, a general feeling of discomfort, muscle pain or cramping.
Lactic acidosis occurs when lactic acid production exceeds lactic acid clearance. The increase in lactate production is usually caused by impaired tissue oxygenation, either from decreased oxygen delivery or a defect in mitochondrial oxygen utilization.

Answer:
Cell membrane - Controls the passage of materials into and out of a cell
Flagella - Acts as a whipping propeller, moving a cell through its environment
Lysosomes - Digest foreign substances and worn out cell parts
Mitochondria - Produce energy (ATP)
Ribosomes - Makes proteins
Cilia - Structures shaped like small oars that beat in unison to move the cell or the liquid around it
Nucleus - Protects DNA and is considered the “brain” of the cell
Golgi Apparatus - Modifies and packages proteins
Explanation:
The cell membrane separates the inside of the cell from the external environment, and regulates substances that enter and leave the cell.
The nucleus contains the genetic material of the cell, and therefore controls all cellular activities. It is also the site of transcription of mRNAs. mRNAs are translated at ribosomes.
The ribosomes are like factories that synthesize proteins through the process of translation.
When proteins have been produced, they are modified, packaged, and transported to their specific sites by the Golgi apparatus.
Mitochondria are energy-producing organelles - the site of cellular respiration.
Lysosomes are membrane-bound sacsin which waste products are digested
Some cells have cilia, which are hair like-structures that beat in unison to aid in locomotion. Another locomotory organelle is the flagella, which is a whip-like structure that helps some single-celled organelles to move.
