Answer:
Mucous membranes
Explanation:
The epidermis (external) and mucous membranes (internal) represent the first non-specific barriers that act against invading pathogens and harmful substances. The mucous membranes separate the external environment surrounding the mucous cells from the body's internal environment. These membranes are considered as selectively permeable barriers that act to prohibit the passage of pathogenic microorganisms (e.g., bacteria) and harmful agents (toxic chemical substances).

Which statement explains why the structure of sickle cells differs from normal red blood cells?
A
The gene mutation affects protein synthesis.
B
The gene mutation prohibits DNA replication.
C
The gene mutation inhibits the cell’s ability to produce tRNA.
D
The gene mutation affects the cell’s ability to produce ATP.
Answer:
a
Explanation:
The structure of sickle cells differs from normal RBCs because of the gene mutation that affect the protein structure.
Sickle Cells:
These cells look like a crescent moon. They are unable to transport oxygen. This cause anemia in the patient.
It is an inherited disorder in which point mutation in the lead to the different protein structure. This results in the sickled RBCs.
Normal blood cells are round in shape and able to transport oxygen.
Therefore, the structure of sickle cells differs from normal RBCs because of the gene mutation that affect the protein structure.

Which of the following is NOT a common element in the human body? Select all that apply.
Answer:
Helium and carbon dioxide
The elements that are not common in human body are carbon dioxide and helium. The correct options are B and E.
What are elements?A chemical element is a type of atom with a specific number of protons in its nucleus, including the pure substance made up entirely of that species.
Chemical elements, unlike chemical compounds, cannot be broken down into simpler substances by any chemical reaction.
The human body is made up of only six components: oxygen, hydrogen, nitrogen, carbon, calcium, as well as phosphorus.
Sulfur, potassium, sodium, chlorine, and magnesium make up about 0.85% of the remaining mass. All 11 of these elements are necessary.
Carbon dioxide and helium are elements that are not found in the human body.
Thus, the correct options are B and E.

H __ __
h __ __
What percentage of offspring would be deaf?
25%
50%
75%
100%
Answer:
3/4 (3 out of 4) of the genotypes are deaf. 3/4 is also equal to 75%. So 75% of the offspring produced will be deaf.
Explanation:
The way the punnet squares work is the top allele on the left combines with the left allele on the top, the top allele on the left is combined with the top allele on the right, the bottom allele on the left is combined with the top allele on the left, the bottom allele on the left is combined with the top allele on the right.

Harry had been learning about joints in one of his classes at school. On the way to the emergency room he tried to recall what types of tissues made up the different joints. He knew ligaments, tendons, and other connective tissues associated with joints often did not heal quickly. He wasn't sure whether it would better to have broken a bone or to have sprained something. Correctly match each tissue type to the sentence. Some of the words may be used more than once.
__________ is what makes up the war criage of synovial joints.
A symphysis is an amphithjoint where__________ joins adjacent bones
Epiphyseal platos are the growth plates of long bones which are made up of ___________ and are an example of a synchondriosis.
a. Dense regular conective tissue
b. hyallne cartilage
c. Dense irrregular conective tissue
d. fibrocartilage
Answer:
The correct answer is -
1. hyaline cartilage
2. fibrocartilage
3. hyaline cartilage
Explanation:
1. The hyaline cartilage covers the articular cartilage of the synovial joint that is translucent or clear as glass-like cartilage that has a firm consistency and a high amount of collagen.
2. A symphysis is an amphiarthrotic joint which is a fibrocartilagenous joint that joins with the adjacent bone. This is a very tough or strong tissue.
3. The growth plate of the long bone or epiphyseal plates are examples of synchondrosis,which is a hyaline cartilage composed tissue.

what is the molarity
Answer:
Hope its help you
if wrong then sry
Answer:
Explanation:
the number of moles of solute per liter of solution. molar concentration
Molarity (M) is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of a solute per liters of a solution. Molarity is also known as the molar concentration of a solution. Explanation: To get the molarity, you divide the moles of solute by the liters of solution. Molarity=moles of solute liters of solution. For example, a 0.25 mol/L NaOH solution contains 0.25 mol of sodium hydroxide in every litre of solution.
Explain the difference between independent variables, dependent variables, and control variables.
Answer:
Independent: Purposely altered
Dependent: Changes with respect to the independent being altered
Controlled: Never changes
Explanation:
An independent variable is a variable in which does not rely on other pieces/variables of an experiment to assume a value. In other words, it does not change when other variables change. However, it can be changed intentionally by the scientist.
A dependent variable is a variable in which its change in value relies on other pieces/variables of an experiment to assume a value. So, if the indeoendent variable is changed, the dependent variable will change as well. The opposite is not true though - if the dependent variable changes (for whatever reason), the independent variable hasn't necessarily been changed.
A controlled variable is a variable that stays CONSTANT throughout an experiment. It is never changed, and nothing will change it. An example of a control variable is the number of participants in a study: no more participants are being added, and no participants are being removed. The number of participants remains STATIC throughout the study.
This model shows the process of protein synthesis including transcription and translation. What is the best explanation for what is
occurring at the arrow (translation)?
Answer: The answer is C
Explanation:
During the process of protein synthesis, the best explanation for what is occurring at the arrow is as follows:
The codon on the mRNA pairs with the anticodon on the tRNA which transfers amino acids into the proper sequence to form a protein.What is Protein synthesis?Protein synthesis may be defined as a biological process through which cells make proteins in order to accomplish metabolic functions that facilitate the survival of living organisms. The process of protein synthesis terminates with the help of two stages. They are as follows:
Transcription.Translation.Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. While the process of translation acquired the transfer of genetic instructions from the mRNA to the sequence of amino acids in order to form proteins. This takes place in the cytoplasm of the cell.

Which of the following will most likely decrease genetic diversity?
А increased reproduction
B selective breeding
C mutations
D immigration
Selective breeding dangers reduced genetic diversity can result in certain insects or diseases attacking, which could be quite devastating. Thus, option B is correct.
What is the cause of selective breeding in genetic diversity?Selective breeding can contribute to a large reduction in the genetic diversity of farmed populations, endangering long-term evolutionary progress and limiting populations' ability to adjust to environmental changes.
Unknowingly selecting uncommon illness genes as part of a desirable characteristic might cause difficulties with particular organisms, such as the high prevalence of deafness in Dalmatian dogs.
Genetic diversity is typically reduced by selective breeding, since only a few individuals are employed to produce enormous numbers of offspring. The population's survivability may be impacted by this.
Therefore, selective breeding will most likely decrease genetic diversity.
