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.
I'm building a carbon atom. I've been told that the atomic number of carbon is 6, which means
that the carbon atom has protons.
Answer:
The carbon has 6 protons
Explanation:
The atomic number equals the quantity of protons and electrons in a neutral element.
Answer:
6 protons
Explanation:
The atomic number of an atom signifies the number of protons found in the the nucleus of the atom of a specific element.
It also represents the number of electrons, but only in an neutral or uncharged atom.
We are told the atomic number of carbon is 6. We also know that the atomic number is equal to the number of protons. Therefore, the carbon atoms has 6 protons.
A biology student wanted to determine if there is a relationship between resting heart rate and time spent exercising per week.
Answer:
YES, there is a relationship between resting heart rate and physical activity.
The higher the physical activity, the better the physical performance, the better the cardiac contractile quality, therefore the lower the heart rate at rest.
Explanation:
The heart is a muscle that is trained like the rest, when practicing physical activity it contracts and expels blood more often and more intensely.
Thus generating that the contractile power is more effective, that is to say that in each bombardment it ejects more blood into the aorta, therefore there will be less effort at rest.
This is how training generates hypertrophy of myocytes, they contract better, generate blood ejection to the vascular system in a more efficient contraction compared to sedentary, therefore the oxygenated volume will not have to be replaced immediately, thus generating the heart have to beat or eject more slowly.
By contracting fewer times per minute, we are faced with the phenomenon of decreased heart rate, this is measurable by taking the pulse of an athlete at rest and comparing it with a sedentary person also at rest.
Answer:
69 bpm
Explanation:
1.) There is an inverse trend seen in the graph. Students who do less exercise tend to have a higher resting heart rate, while students who do more exercise tend to have a lower resting heart rate.
2.) Using the line created by the data points, we can determine that students who exercise around 3 hours per week seem to have resting heart rates between 68-72 bpm.
3.) The correct answer is: 69 bpm
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.
50 POINTS!! In the carbon cycle, all animals must consume other organisms because A. they can not absorb enough carbon from water. B. they cannot absorb carbon directly from the air. C. they are in competition with plants for available carbon. D. they require carbon to perform photosynthesis.
Answer:
C
Explanation: A fish can live in water and get carbon in the air bubbles but it's not enough carbon to thrive off of so the fish may need to eat other fish or plankton in the water. The second example A wolf would get its carbon from both the air and water but would still need extra carbons so that is why it would hunt a deer to consume its carbons. Also, the deer would get its carbons from the air, water, and grass. the grass would get its carbons from water and air. NOW DO YOU GET IT EVERYTHING IS CARBONS AND LIVES OFF OF THEM AND IT WILL ALWAYS BE THAT WAY!

Can someone give me a description of a biologist at least 2 sentences
Answer:
A scientist specializing in the science of biology is a biologist. Biologists observe, explore, and ask questions about topics in fields such as health, technology, and the environment.
Explanation:
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.

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.
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).
Which of the statements best describes the way you would engineer bacterial cells to produce a human protein?A. One restriction enzyme would be used to cut the donor human DNA and a different one would be used to cleave the vector DNA. B. One restriction enzyme would be used only to cleave the vector DNA. C. One restriction enzyme would be used only to cleave the donor human DNA. D. The same restriction enzyme would be used to cut both the donor human DNA and the vector DNA
Answer:
The correct answer is option D. The same restriction enzyme would be used to cut both the donor human DNA and the vector DNA.
Explanation:
The way one could engineer bacterial cells to produce a human protein is by allowing bacteria to taking up the recombinant DNA. This recombinant DNA are inserted in the form of the vectors.
Recombinant DNA technology or RDT allows individual fragments of DNA from any donor human genome to be inserted into vector DNA molecules with the help of the specific restriction enzyme for both vector DNA and donor DNA.
Thus, the correct answer is option D. The same restriction enzyme would be used to cut both the donor human DNA and the vector DNA.
The same restriction enzyme would be used to cut both the donor human
DNA and the vector DNA.
Restriction enzymes are also referred to as endonucleases and this involves
the cutting of a sequence at a particular end on the human and donor DNA
for various purposes such as modification etc.
The same restriction enzyme would be used to cut both the donor human
DNA and the vector DNA because it results in complementary sticky ends
being produced which is vital in DNA formation.

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.
Thank you

Why are the testes located in the scrotum rather than inside the ventral body cavity? _______________________________
Answer:
The correct answer is - to provide a slightly cooler temperature.
Explanation:
The scrotum is a sac pf skin and superficial fascia that contains testes present outside of abdomopelvic cavity or ventral body cavity, hanging provides a slightly cooler temperature f at roots of penis.
Testes produces sperm, for the sperms it require to be cooler temperature than the body cavity or optimal sperm production will be hampered. Scrotum gives 3 degree temperature less than the body cavity.
Thus, the correct answer is : to provide a slightly cooler temperature.
