What is the smallest number of nucleotides that must be added or subtracted to change the triplet grouping of the genetic message?Group of answer choices
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.

The provides a rigid structure that gives the cell its shape. The helps to transport ions, nutrients, and waste. allow DNA to be transferred from one bacterium to another.
Answer:
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.

2) In 1554, a cholera outbreak occurred in London. Cholera is a disease that causes intense diarrhea and can be fatal. At the time, many people believed that diseases were caused by "bad air. John Snow had another idea; he thought that cholera was caused by something in the environment where people lived. He went door to door and made a map showing households that had cholera] He found that most of the cases were near the Broad Street Water Pump. John Snow made a case that the water from the pump was making people sick and the pump was shut down. REASONING: If water was the cause of the sickness, then ...
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.

Describe the function of each organelle. Nucleus Ribosome Endoplasmic reticulum Golgi apparatus
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).
What are the function of organelle in cells?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.

One of the five characteristics of life is the need for energy. Which of the four basic needs meets this need? (PLEASE ANSWER IN 5 MINS)
-water
-air
-food
-place to live
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.

An animal cell left and a plant cell right are shown which two cell parts are most likely found in both types of cell
scientific understanding can always be challenged snd even changed, with new ways of observing and with different interpretations
Answer:
True
Explanation:
Conclusions made from scientific research or understanding can always be challenged by anyone with new ways of observing and with different interpretations. This is the essence of the repeatability or reproducibility of scientific experiments.
Scientific research must be reproducible and if the earlier conclusions or understanding is found to be somehow inadequate with overwhelming evidence, they are modified or even changed completely in order to accommodate new facts.
Hence, the emergence of new ways of observing different interpretations can lead to new/different conclusions from the same research. If the new conclusions gain enough evidence, it becomes the new theory.
Seeing is believing. Do you agree or disagree with the statement above? Be sure to explain your reasoning and use examples from this lesson to support your view. connect to: the ideas of atomic theory, the scientists who helped develop atomic theory, the tools and techniques that were used to study matter, the conclusions that were, drawn from the study of matter, Then, examine the statement.
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.
An investigation was done to see if keeping the lights on for different amounts of time each day affected the number of eggs chickens laid.
Answer:
This question is incomplete, the complete part is asking to identify the variables of the experimental statement i.e. dependent and the independent variables.
Independent variable: different amounts of time light is on
Dependent variable: Number of eggs laid by chicken
Explanation:
In a scientific experiment, variables, which are factors that can be altered, are used. These variables are independent and dependent variables.
An independent variable is that variable that is subject to manipulation or control by the experimenter in order to bring about a change in the dependent variable. For this experiment, the independent variable is the DIFFERENT AMOUNT OF TIME LIGHT IS ON.
On the other hand, a variable is said to be dependent if it is the measurable or responding variable. The response of the dependent variable is dependent on the independent variable. In this experiment, the dependent variable is the NUMBER OF EGGS LAID BY CHICKENS. The number of eggs laid (dependent variable) is dependent on the amount of time light is on (independent variable).

3. Make a claim about what you think the average pH is in your intestine. Give
evidence from the graph to support your claim.
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.
What hormones lead to a girl being more or less feminine? Explain in detail please
Your question has been heard loud and clear.
Hormones like oestrogen and progestrone play a good part in being more feminine. More the levels of oestrogen , more is the increase in sexual desire. Whereas progestrone reduces the sexual desire and makes you more feminine in nature.
Hormones like testosterone are present in the female body too and they balance the difference between being too female and normally female. High levels of testosterone makes a girl less feminine , the same way that oestrogen is present in the male body too , to balance the difference between being too male and normally male , high levels of oestrogen in a male's body makes them less male and more feminine.

A woman who is a carrier for colour blindness (X-linked recessive) has children with a man who has normal colour vision. A. What are the genotypes of the man and woman? (2 marks) B. What percentage of their children do you expect to be colour blind? (1 mark) C. What proportion of their children will be carriers of the allele for colour blindness? (1 mark) D. Is it possible for the couple to have a girl who is colour blind? Why or why not? (2 marks)
Answer:
Explanation:
The Genotype of the woman is XCbXN
The man XNY
Since the allele for the color blindness is carried on one of the X -chromosomes of the carrier mother, then the male children will be color blind or carrier deopending on the defective gene they inherited. Since they will receive the defective or normal allele from the mothers,but the female will carriers or normal because they will inherit either defective allele or normal allele from the mother,but normal X allele from the father.
Assuming the colorbind gene was inherited by One of the boys, and the girls take the defective genes
1. XNY vs XCbXN.Then the one of the boys will be colorblind and the one of girls will be carriers. XNXCb, XNXN, XCbY,XNY 50 %
2.If the two boys take the effective genes from the mothers. and none of the girls take the defective alelle
Then the two boys will be colorblind and the girls will be carrries XcbY,XcbY and XNXN XNXN.(normal girls).
The proportions that will be the females since the girls can only take the defective allele from one of the normal and defective allele from the mother. Assuming the girls take the defective allele from the mothers and take normal from the father,they will all be carriers,since the X of the father is normal.
They can not have a color blind girl.Since the father is normal It takes two colorblind X-chromosome to give a girl.
