A student is presented with a model of a digestive system and is asked to remove one structure (small or large organ) that will have the largest impact on decreasing chemical digestion. Which structure should the student remove
Answer:
Small intestine
Explanation:
Digestion is the process of breaking down food molecules into simpler and usable forms by the body cells. The process of digestion involved the mechanical aspect and chemical aspect. The mechanical one deals with using physical means like chewing to break down the food particles.
However, the chemical one deals with the usage of chemically-secreted enzymes to work on the food molecules. Lots of digestive organs are involved in this chemical digestion, but, the most of chemical digestion takes place in the SMALL INTESTINE. The small intestine is where most of the chemical digestion occurs including absorption.
Hence, according to this question, the student should remove the SMALL INTESTINE because it will have the largest impact on decreasing chemical digestion.

Weak hydrogen bonds between the nitrogenous base pairs hold the two strands of DNA together. Why are the strands held together by weak hydrogen bonds instead of covalent bonds
Answer:
Explanation:
Hydrogen bonding is usually occur wen interaction with hydrogen atoms occur.
Hydrogen bonds joins DNA polymers because an hydrogen atom occur on on one base which is called hydrogen bond donors and another oxygen or nitrogen atoms on the base across from it which is called hydrogen bond acceptors.
Adenine “A” a purine and Thymine “T” a pyrimidine each have a donor and one acceptor, whereas Cytosine “C” a pyrimidine has one donor and two acceptors, and Guanine “G” a purine has one acceptor and two donors.
This atoms allows for hydrogen bond between them that gives them structure of DNA molecule.
A nucleotides is hydrogen bonded to T nucleotides while C nucleotides is hydrogen bonded to G nucleotide this is called complementary base pairing.
What is a bacteria that is beneficial to humans and what does it do?
How will you react if I tell you that your body consists of 1 to 2.6 kg of bacteria? Shocked? Well, I can imagine your surprised face. Most people believe that bacteria are dangerous and are responsible for diseases and infections but this isn’t true. In fact the truth is, most of the bacteria are helpful in the functioning of a living body and are also capable of performing many other useful functions. These beneficial bacteria are present in huge numbers inside as well as outside our body. Well let’s check out various types of beneficial bacteria which not only help in proper functioning of our body but also contribute in many other functions in and outside the body. Some of the examples of helpful bacteria are Bifidobacterium, Rhizobium and E.coli.
Beneficial Bacteria – to Humans
Human body has millions of bacteria which participate in different functions of the body. As you know the amount of bacteria present in the body varies from 1 to 2.6 kg, this volume contains a huge number of bacteria. These bacteria can be present in all parts of the body but mostly they are found in the intestine where they help in the process of digestion. They also play a very important role in preventing bacterial infections in genital parts, like yeast infections. Some beneficial bacteria to humans are helpful in maintaining the pH of the body. Some are even involved in protecting the skin from many infections.
They are also helpful in the production of vitamin K and have an important role to play in the functioning of immune system. One of the most common bacteria which are helpful for humans is Escherichia coli. This bacteria is associated with the process of digestion. It is present in the large intestine where the maximum digestion takes place. These bacteria release enzymes which help in the process of digestion and synthesis of various vitamins and nutrients. Beneficial bacteria are also very helpful for the pregnant women. They reduce the chances of postpartum complications and also protects the baby from fungal infections.
Answer:
Probiotics are live bacteria that are good for us, that balance our good and bad intestinal bacteria, and that aid in digestion of food and help with digestive problems, such as diarrhea and bellyache. Bacteria that are examples of probiotics are Lactobacilli and Bifidobacterium.

transcription; at the ribosome
The process is identified by number 1 in the diagram and where in the cell does this process occur is translation, at the ribosome. Thus option 3 is correct.
What is translation?Translation is defined as the process by which a messenger RNA (mRNA) molecule's sequence is converted into an amino acid sequence during protein synthesis.
It is also be defined as when DNA is converted to RNA in the cell's nucleus, the process through which ribosomes in the cytoplasm or endoplasmic reticulum synthesize proteins. Gene expression refers to the entire process.
Initiation, elongation, and termination are the three phases of an mRNA molecule's translation by the ribosome.
Thus, the process is identified by number 1 in the diagram and where in the cell does this process occur is translation, at the ribosome. Thus option 3 is correct.

In a plant species, the allele for dark green leaves (D) is dominant over the allele for light green leaves (d). A plant with Genotype (Dd) is crossed with a plant with genotype (did). What percentage of the offspring are expected to be hybrid for the leaf color trait. A 0% B 25%. C.50%. D 75%
The percentage of the offspring that is expected to be hybrid for the leaf color trait is 50%. The correct option is C.
What are alleles?The trait is caused by a pair of two alleles on the chromosome, and there are two possible outcomes. The dominant allele, which is typically written in capital letters and will control the organism's phenotype even in the presence of the other allele, is the one that has the ability to silence the other allele.
It is used in biology to refer to inherited traits that do not manifest in the phenotype of the individual who possesses them but may do so in their offspring.
Recessive alleles, which are only expressed when they are homozygous, are this other type of allele. Both heterozygous and homozygous genotypes exhibit the dominant allele.
Dd is crossed by dd.
100 / 2 = 50%.
Therefore, the correct option is C.

Need help plz!!! Trying to catch up on biology anything can help!!!!
Answer:
See the answer below
Explanation:
The control group in an experimental study is the subject group that is not administered the treatment variable. The control group forms the baseline for comparing the effects produced by the treatment variable on the experimental group.
Thus, in this case, the control group would be the 10 mice that were not exposed to the radio waves.
The independent or the manipulated variable, in this case, is the exposure or otherwise of the mice to the radio waves.
The dependent variable is the actual variable that is going to be measured, otherwise known as the effect variable. In this case, the dependent variable would be the strength of the mice measured by their ability to push the block of wood blocking their food.
Since 8 out 10 mice and 7 out of 10 mice were able to push the wooden block in both the experimental and the control group, Bart's conclusion should reject the hypothesis that the radio waves make mice extra strong.
Bart's experiment can be improved by increasing the number of subject mice in each group. The more the number of subjects, the more the accuracy of the outcome would be.
Use the following questions to write your conclusion to your lab report.

Some genes are important enough to be called "molecular switch" or "master" genes. What is the purpose of these genes?
A. They control when other genes are expressed
B. They determine the organization of the genome
C. They regulate cell metabolism
D. They modulate the rate of translation
Answer:
Genes called "molecular switch" or master genes have the purpose of control when other genes are expressed (option A).
Explanation:
Master gene is so named because it has the function of controlling the behavior of other genes, organizing their functions and regulating when they can be expressed.
The name of molecular switch is synonymous with the master gene, since its activation determines the genetic regulation necessary to establish cell differentiation and even the determination of the sex of some species.
The other options are not correct because:
B. Master genes do not determine the organization of the genome .
C. Regulation of cell metabolism depends of substances as hormones and enzymes.
D. The rate of translation does not depend on the activity of master genes.
