Before Pasteur's experiments using beef broth and flasks with S-shaped tubing, most people thought that new cells formed by____
Answer:
spontaneous generation
Explanation:
Spontaneous generation is the idea that living organisms arise from nonliving matter. Louis Pasteur was a French chemist who designed a series of experiments to determine whether a sterile nutrient broth could spontaneously generate microorganisms. He added nutrient broth to two flasks, curved their necks into S shapes, and finally boiled the broth to eliminate any potential microorganism. Pasteur did not observe any microorganisms in the flasks with the S-shaped necks, thereby showing that microorganisms present in the air were responsible for contaminating nonliving material and thus rejecting the idea of spontaneous generation.

what are some non examples of hydroshere
The hydrosphere is made up of all the water on the planet, including the water found below the surface and in the atmosphere. A planet's hydrosphere may be liquid, vaporous, or composed of ice. The three surface water bodies on Earth are oceans, lakes, and rivers.
What are some non examples of hydrosphere?It comprises all surface waters that are liquid or frozen, groundwater that is contained in soil or rock, and atmospheric water vapor. The hydrologic cycle continuously circulates almost all of these waters. In wells and aquifers, it can also be found underground as groundwater.
Within the hydrosphere, water circulates in a cycle. Clouds contain water that eventually falls to Earth as rain or snow.
Therefore, Rivers, lakes, and seas are where this water gathers. The cycle is then restarted by its evaporation into the atmosphere. The water cycle refers to this.

why is the linner wall of alimantary canal not digisteg although the digestive enzymes can digest all the materials that make cell?
Answer:
There are no options to this question but it can be answered by giving a general explanation. The answer is:
Because the digestive enzymes are not in direct contact with the cells that make up the walls of the alimentary canal. The walls are protected by mucuous lining.
Explanation:
Digestion of our ingested food is an important process for the effective functioning of our body system. Digestion is the process whereby food, which are usually macromolecules, are broken down into simpler molecules usable by the body. After food is taken in from the mouth (ingestion), it must be broken down by chemical and mechanical means.
The chemicals means is through digestive enzymes, which are proteinous chemical substances. The digestive system consists of the alimentary canal or digestive tract, which is a tube-like organ that forms the path for food passage. Since digestive enzymes secreted during digestion can disintegrate every macro biomolecule e.g protein, carbohydrate etc, it can also break down the molecules that make up the cells of the tract wall.
However, the digestive enzymes does not break down the cells of the canal's wall because the body system secretes mucus, which lubricates the passage of food along the canal. It also prevents the digestive enzymes from coming in contact and acting on the macromolecules that make up the cells of the walls of the alimentary canal.
The lac operon in Escherichia coli Group of answer choices promotes the expression of lactose-utilizing enzymes when lactose is absent from the environment. prevents lactose-utilizing enzymes from being expressed when lactose is absent from the environment. prevents lactose intolerance. prevents lactose-utilizing enzymes from being expressed when lactose is present in the environment.
Answer:
The correct answer is - prevents lactose-utilizing enzymes from being expressed when lactose is absent from the environment.
Explanation:
The lac operon or the lactose operon is a operon that is essential for the many bacteria like Escherichia coli for metabolism and transport of the lactose.
In the presence of the lactose in the environment of the cell the lac genes are expressed due to the isomer of of lactose called allolactose binds to the Lac repressor protein and do not allow to bind it to lac operator. But in the absence of the lactose, the lactose utilizing enzymes are not expressed due to repressor bind to the lac operator and prevents the binding of RNA polymerase to the promoter.

Groundwater is used for:
irrigation
drinking water
fire hydrants
wells
Answer is: All of the above
Explanation:
Groundwater supplies drinking water for 51% of the total U.S. population and 99% of the rural population. ... 64% of groundwater is used for irrigation to grow crops. Most wells do not get their water from underground rivers. Hydrants are connected to our drinking water.
Answer:
irrigation drinking waterfire hydrantsExplanation:
The water is either stored in aquifers or slowly pulled downhill by gravity, where it will eventually seep into streams, lakes, and oceans. Wells can be drilled into aquifers to pump out water for irrigation, drinking, fire hydrants, and other uses. Many local and state water departments depend on groundwater for public use. In 2000, almost 20 percent of freshwater used in the United States came from groundwater.

How is genetic information preserved during the copying of DNA? View Available Hint(s) Hint 1.opened hint How is genetic information preserved during the copying of DNA? The information is preserved because DNA codes for RNA, which codes for protein. Genetic information is preserved in the linear sequence of the building blocks A, T, G, and C. Genetic information is preserved by base pairing between A and T and between G and C across the two strands of the double helix. The information in DNA is copied into RNA, which is used as a template to copy back to DNA.
Answer:
Genetic information is preserved in the linear sequence of the building blocks A, T, G, and C.
Explanation:
Deoxyribonucleic acid contains genetic information in the bases i.e the Nitrogenous bases Adenine, thymine, Guanine, cytosine are the store for coding genetic information, in them lies the genetic information of an organism. Each base is coding for different gene the is found in the organism.
After the information on the DNA have been moved to an intermediary Ribonucleic acid (RNA) it is been translated into an amino acid a building block of protein containing all the genetic information coded for by the Nitrogenous base.

Menstrual Phase
Follicular Phase
and Luteal phase
Thanks!!!
Answer:
(menstrual phase) this is the phase where the unfertilized ovum and endometrium that was formed in readiness for implantation slough off or come out due to a sudden drop in progesterone levels
(follicular phase) this is where the graafian follicle in the ovary develops. from primary follicles due to secretion of follicle stimulating hormone by the pituitary gland and matures there after due LH hormone which will also stimulate the ovary to release the ovum
(luteal phase)this is the phase after the ovum has been released where the remains of the ruptured graafian follicle undergo reorganization to form a corpus luteum/yellow body which now produces progesterone which causes thickening of endometrium in readiness for implantation
hope this helps
Answer:
The menstrual cycle is the regular natural change that occurs in the female reproductive system that makes pregnancy possible. 2) The follicular phase is a phase of the estrous cycle during which follicles in the ovary nature from primary to a fully mature grafian follicle.It ends with ovulation.3) The luteal phase begins during the second half of a menstrual cycle normally lasting around 12 14 days after the ovulation and it is responsible for producing progesterone.
