Answer:

The intestinal pH is a neutral pH, that is, 7.

If this pH is not met, it does not tend to neutralize the stomach enzymes will not be regulated, that is to say that when we digest the food bolus the gastric enzymes that are dumped together with the food in the form of chyme to the intestine are active because the low pH and the acidic medium is what triggers its action, when encountering intestinal neutrality that ranges from 5 to 8 in terms of pH, these enzymes are inactivated and stop working at the intestinal level, giving rise to the activation of intestinal juices.

Explanation:

https://pubmed.ncbi.nlm.nih.gov/21947475/ in this link I leave you a scientific evidence of pubmed associated with how intestinal pH is regulated through the mucus that is secreted in it and even how it is related to it bacterial growth of both commensal flora and other bacteria.

The intestinal pH is essential to be maintained since it regulates the immune system, the predominant commensal flora that protects us from serious opportunistic infections and the enzymatic activity that helps us assimilate nutrients, it is essential to note that in the intestine is where more absorption of Nutrients are fulfilled compared to the rest of the organs of the gastrointestinal tract.

2. blow dryers instead of paper towels, ask students to bring utensils instead of handing out plastic ones

Answer:

The correct answer is - one.

Explanation:

A triplet code or triplet grouping of the genetic message is a code that carries the genetic information and help in providing the enough information in the DNA to arrangement of all 20 amino acid. It can make 64 cobinations of genetic code by just triplet code.

Adding or subtracting the one nucleotide of the triplet code would change the genetic code or message and cause mutation or leads to different amino acid and protein.

Thus, the correct answer is- one.

Answer:

Physical science can be described as all of the following:

A branch of science (a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe).

A branch of natural science – natural science is a major branch of science that tries to explain and predict nature's phenomena, based on empirical evidence. In natural science, hypotheses must be verified scientifically to be regarded as scientific theory. Validity, accuracy, and social mechanisms ensuring quality control, such as peer review and repeatability of findings, are amongst the criteria and methods used for this purpose. Natural science can be broken into two main branches: life science (for example biology) and physical science. Each of these branches, and all of their sub-branches, are referred to as natural sciences.

Hope this helps ma dude!  

Answer:

I would go with C) food because food gives us energy, healthy veggies give us energy and unhealthy junk food really doesn't give us as much energy and makes us fat. Not air because air is the need for life, not energy, and not a place to live since that really doesn't give us energy. It's not water, although we can't live after a few days without water due to dehydration, water does not give us energy it just keeps our bodies and living things hydrated.  

I hope this helps you :)

Answer:

A. a base pare of deletion

Explanation:

A base pair deletion is a mutation where one nucleotide is removed during DNA replication. The base-pair deletions produce frameshift mutations, i.e., they cause genetic modifications that alter the Open Reading Frame (ORF) of the corresponding protein. Examples of human diseases caused by deletion mutations include, among others, cystic fibrosis and Williams syndrome.

Explanation: Plastic allows us to keep water in a bottle like if your going to arizona and you are dying of thrist, then you'll have water in a bottle or as we call "A water bottle". Plastic bags were invented to save the planet, according to the son of Swedish engineer Sten Gustaf Thulin who created them in 1959. The bags were developed as an alternative to paper bags, which were considered bad for the environment because they resulted in forests being chopped down.

Answer:

I disagree.

Explanation:

For many years the phrase "Seeing is believing" has been propagated as a way to question and verify the information that reaches us. "Seeing is believing" reflects an evidential thought, where something must be witnessed and touched to be credible. We cannot agree with that.

Agreeing with this phrase is a way of denying all the scientific and technological advances that humanity has gone through. This is because there are countless things that could be scientifically proven and that we cannot see, such as DNA, atoms, molecules, RNA, among others. Atoms, for example, were proven through scientific techniques and devices that were modernized and allowed us to reach a conclusion without being able to see the atoms, but knowing that they are real.

We must not be denialists, especially in scientific matters, because science is one of the main factors for the advancement of society, without scientific advancement there is no progress.

Therefore, we must motivate the phrase "Seeing is believing" to "Proving is believing", which is very rational and coherent.

See the answer below

Explanation:

Since bacteria are prokaryotes, they have no nucleus and membrane-bound organelles. The outside of a bacterial cell is protected by a structure called a capsule. The cell wall provides a rigid structure that gives the cell its shape. The cell membrane helps to transport ions, nutrients, and waste. The plasmids allow DNA to be transferred from one bacterium to another.

The bacteria are microscopic organisms that are generally classified as prokaryotes. The prokaryotes lack nucleus and other membrane-bound organelles, unlike the eukaryotes. The bacteria cells are enclosed in a protective structure known as the capsule. Immediately after the capsule is the cell wall whose components vary depending on whether the bacteria is Gram-positive or negative.

Towards the innermost part of the cell, after the cell wall is the cell membrane. It acts as a channel for the transport of materials in and out of the cell. Some bacteria cells have short, circular, extrachromosomal DNA known as plasmids which can be transferred from one cell to another.

Answer:

A strand of genetic material ... is also A.P.EX approved

DNA stores the genetic code, chromosomes are thread-like structures, and sister chromatids are two halves of chromosomes and a strand of DNA. Thus, option A is correct.

The genetic code is stored in every cell of your body in the form of deoxyribonucleic acid (DNA). It makes your body's instruction manual. The DNA molecule is packaged into thread-like structures called chromosomes in each cell's nucleus.

The term "homologous chromosome" refers to chromosomes that share the same genetic foundation but may also have variants caused by replication. The two halves of a given chromosome that are held together at the centromere are called sister chromatids.

After the cell has gone through the process of DNA replication in order to get ready for cell division, chromosomes are known as "replication chromosomes" emerge.

Therefore, DNA stores the genetic code, chromosomes are thread-like structures, and sister chromatids are two halves of chromosomes and a strand of DNA. Thus, option A is correct.

Answer:

The answer is 50%.

Explanation:

If we cross the two genotypes given in the question as Ll and ll, we can see that 50% of the offspring will have Ll as the genotype and the other 50% will have ll as the genotype.

Since L is the dominant gene, all the Ll genotypes will have long hair as a result of the dominant gene.

Answer:

Nucleus- Contains the cell's DNA; the control center of the cell

Ribosome- Synthesises proteins

Endoplasmic Reticulum- makes lipids and other materials for use inside and outside of the cell; breaks down harmful substances; transportation within a cell

Golgi Apparatus- processes and bundles macromolecules like proteins and lipids as they are synthesised

The Golgi apparatus is where the ribosomes of the ER produce proteins, which are then packaged in a membrane made of lipids and exported from cells. Charged molecules are held in the Golgi before being released and entering the cytoplasm (secretory vesicles).

An organelle is a microscopic structure that, like an organ in the body, has one or more specific tasks to carry out within the cell.

The nucleus, which house genetic material, the mitochondria, which generate chemical energy, and the ribosomes, which put together proteins, are some of the more significant cell organelles.

All cellular organelles are composed of macromolecules such lipids, proteins, nucleic acids, and carbohydrates (DNA, RNA).

Therefore, Nucleus Ribosome Endoplasmic reticulum Golgi apparatus function is coordinated together.

The correct answer to this open question is the following.

Although there are no options attached, we can say the following.

If water was the cause of the sickness, then Dr. Snow had it well shutting down the Broad Street Water Pump.

Dr. John Snow was an English Obstetrician that tried to demonstrate in 1854 that cholera was the cause of many deaths in the water pump of Broad Street, Soho, London. At that time, scientists thought that the disease spread due to bad air, although Dr. Snow tried to prove that contaminated water was the cause. So the decision to shut down the pump was correct, although the London authority had its doubts.

Chemical changes are defined as changes which occur when a substance combines with another substance to form a new substance.Alternatively, when a substance breaks down or decomposes to give new substances it is also considered to be a chemical change.

There are several characteristics of chemical changes like change in color, change in state , change in odor and change in composition . During chemical change there is also formation of precipitate an insoluble mass of substance or even evolution of gases.

There are three types of chemical changes:

1) inorganic changes

2)organic changes

3) biochemical changes

During chemical changes atoms are rearranged and changes are accompanied by an energy change as new substances are formed.
