Q. What are the different ways in which glucose is oxidised to provide energy in the various organism ?
Q. How is oxygen and carbon dioxide transported in human beings ?
Answer:
Hey mate......
Explanation:
This is ur answer.....
1A) There are 2 ways:-
• Anaerobic Respiration.
The anaerobic respiration process takes place in the absence of oxygen.
• Aerobic Respiration.
In aerobic respiration, breakdown of pyruvate takes place in the presence of oxygen to give rise to 3 molecules of carbon dioxide and water.
2A) Oxygen is transported from lungs to body cells in the form of oxyhemoglobin . the main 2 gases exchanged are 02 & C02 . 02 is absorbed by blood capillaries from lungs alveoli by diffusion while C02 is absorbed by blood alveoli from blood capillaries by diffusion.

Select the correctly described examples of host defense mechanisms. Check All That Apply Innate anatomical and physiological barriersInnate anatomical and physiological barriers Innate cellular and chemical defensesInnate cellular and chemical defenses Innate host defenses due to B and T cells and their productsInnate host defenses due to B and T cells and their products Use of drugs and antibioticsUse of drugs and antibiotics Specific recognition of invaders by physical barriersSpecific recognition of invaders by physical barriers
Answers: examples of host defence mechanism include: Innate anatomical and physiological barriers, Innate cellular and chemical defenses.
Explanation:
The capability of the human body to resist almost all types of organisms or toxins that tend to damage the tissues and organs is known as IMMUNITY. This host defence mechanism can be classified into INNATE or adaptive immunity.
The immunity that results from general processes, rather than from processes directed at specific disease organisms is called the INNATE IMMUNITY. The anatomical and physiological barriers of the innate immunity provides the first line of defence against pathogens. Examples of these barriers of the innate immunity includes:
--> Destruction of swallowed organisms by the low stomach pH and digestive enzymes
--> The vigorous mucociliary clearance mechanisms of the respiratory airways and lungs.
--> Resistance of the skin to invasion by organisms
While examples of innate cellular and chemical defenses include:
--> Phagocytosis of bacteria and other invaders by white blood cells and cells of the tissue macrophage System
--> lysozymes, a mucolytic polysaccharide that attacks bacteria and cause them to dissolute.
--> basic polypeptides which react and inactivate certain types of gram- positive bacteria
-->natural killer lymphocytes that can recognize and destroy foreign and tumor cells.
In a deciduous forest of Maine, there are 300 Falcons living in a certain region at the beginning of the year. Scientists have determined that these Falcons demonstrate exponential growth and that their per capita growth rate is 0.067. What will the population of Falcons be in 5 years?
Answer:
419 Falcons
Explanation:
P= Poe^rt
P= population at time t = ?
Po = initial population = 300
r= growth rate = 0.067
t = time taken = 5 years
P = 300e^(0.067 * 5)
P = 419 Falcons
students are modeling mRNA during the process of protein synthesis. which answer choice correctly describes the model of mRNA strand being transcribed
Answer:
This question lacks options, the options are:
A. the mRNA strand is complementary to the DNA template strand; however, uracil instead of adenine is paired with thymine
B. the mRNA strand is complementary to the DNA template strand; however, uracil instead of thymine is paired with adenine
C. the mRNA strand is an exact copy of the DNA template strand; however uracil instead of adenine is paired with thymine
D. the mRNA strand is an exact copy of the DNA template strand; however, uracil instead of thymine is paired with adenine
The answer is B
Explanation:
Protein synthesis which encompasses how gene is used to synthesize proteins consists of two processes namely; transcription and translation.
- Transcription is the process whereby the sequence of a DNA template is used to synthesize a mRNA strand. The mRNA sequence is synthesized using the COMPLEMENTARY BASE PAIRING RULE, which states that Adenine base (A) will always hydrogen pair with Thymine (T) while Guanine (G) will always pair with Cytosine (C).
This means that the mRNA strand produced is complementary to the DNA template strand that was transcribed. However, Uracil base (U) replaces thymine (T) in the mRNA molecule because Thymine is not found in RNA. Hence, Uracil instead of Thymine pairs with Adenine in the mRNA.
That is;
A - U, T - A, G - C.
Which diagram correctly represents a step in the normal process of human reproduction?
Key
2n = total genetic material of a human cell
n
= one half of the total genetic material of a human cell
Answer:c
Explanation:
The diagram that correctly represents a step in the normal process of human reproduction is n + n = 2n (Option C).
Meiosis is a reductional type of cell division that produces four daughter haploid cells.These meiotic haploid (n) cells are known as gametes or germinal cells.During fecundation, two different germinal cells fuse to produce a diploid zygote.In conclusion, the diagram that correctly represents a step in the normal process of human reproduction is n + n = 2n (Option C).

Why do scientists often use bacteria to produce medicines?
Scientists often use bacteria to produce medicines because of their easy use, genetic manipulability, and genetic ability to produce medicine.
What are the characteristics of bacteria?Scientists often use bacteria to produce medicines because bacteria grow quickly and can be cultured in large quantities. This makes them a cost-effective option for production of large amounts of medicine.
Bacteria also have a simple genetic makeup that is easy to understand that allow scientists to easily produce proteins. Some bacteria have the ability to produce natural compounds containing medicinal properties, such as Streptomyces produces several antibiotics that are used in medicines.
Bacteria can also be genetically engineered to produce new compounds that can be used as new medicines. Bacteria are highly versatile for production of wide range of medicines.
Therefore, bacteria are used for producing medicines because of easy use, genetic manipulability, and genetic ability to produce medicine.

Which type of cell has a nucleus?
Prokaryotic Cell
Or
Eukaryotic Cell
Answer:
Eukaryotic cell
Explanation:
The cell of living organisms have been classified as either eukaryotic or prokaryotic depending on whether or not it contains a NUCLEUS. A prokaryotic cell is a cell that does not contain a membrane-bound nucleus to house its genetic material e.g bacteria, archaebacteria etc.
On the contrary, eukaryotic cells possess a membrane-bound nucleus that houses their genetic material e.g fungi, animals, plants etc. Based on the above explanation, an EUKARYOTIC type of cell produces a nucleus.
