Explanation:
The human body has three primary lines of defense to fight against foreign invaders, including viruses, bacteria, and fungi. The immune system's three lines of defense include physical and chemical barriers, non-specific innate responses, and specific adaptive responses.
The human body possesses several defense mechanisms to protect itself against pathogens (disease-causing microorganisms) and other harmful substances such as innate and adaptive immune system.
Innate immunity is the body's first line of defense and is present from birth. It provides immediate protection against a wide range of pathogens. Adaptive immunity is a specific defense mechanism that develops over time in response to specific pathogens. It provides long-lasting immunity and has the ability to recognize and remember specific pathogens. Both innate and adaptive immunity work together to provide a comprehensive defense against pathogens. Innate immunity provides rapid, general protection, while adaptive immunity offers specific, targeted responses. The coordination between these defense mechanisms helps the body combat infections and maintain overall health.

If 10 glucose molecules enter the Krebs Cycle, how many possible molecules of ATP can be produced?
Answer:
20 molecules of ATP
Explanation:
Krebs cycle or also known as Tricarboxylic acid cycle (TCA) is the second stage of aerobic cellular respiration which occurs in the mitochondria. In the kreb cycle, pyruvate, which was synthesized in the first stage of cellular respiration (glycolysis) is broken down into carbon dioxide (CO2).
However, in the krebs cycle, two (2) ATP molecules is produced per glucose molecule that enters cellular respiration. Hence, according to this question, If 10 glucose molecules enter the Krebs cycle, (2 × 10) = 20ATP molecules will be possibly produced.
Answer:
20 molecules of ATP

Which process is included in the formation of both metamorphic and sedimentary rock?
A.
heating
B.
recrystallization
C.
compaction
D.
weathering
Answer:
C. compaction
Explanation:
The weight on the lower layers increases as the layers of sediment stack up. The soils are pressed together, squeezing out some water mixing in with the sediments. This approach is known as compaction.
The sedimentary series has formed into a sedimentary stone following compaction and cementation.

How can recycling impact the environment? A) It uses less energy to make something from recycled materials than from new materials. B) It increases the amount of landfill space needed. C) It uses more natural resources than new materials do. D) It increases the need for mining, creating jobs.
Answer:
A) It uses less energy to make something from recycled materials than from new materials.
Explanation:
When a recycled material is used to make a new product, it conserves energy because the recycled materials have already been processed once; so making something from it for the second time uses less energy-intensive than the first. For example: Making new aluminium from old products uses 95% less energy than making it from scratch.
Hence, the correct answer is "A)"
How the Law of Conservation of Matter and Energy is conserved during these processes based on the numbers of molecules of the reactants and products?
Explanation:
The law of conservation of matter states that in any given system that is closed to the transfer of matter, the amount of matter in the system stays constant.
The law of conservation of matter says that in chemical reactions, the total mass of the products must equal the total mass of the reactants.

What will be the results in the F2 generation after a monohybrid cross?
all recessive traits
3/4 dominant and 1/4 recessive
all dominate traits
1/3 dominant and 2/3 recessive
Answer: [tex]\dfrac34[/tex] dominants and [tex]\dfrac14[/tex] recessive.
Explanation:
Mendel's monohybrid cross is definied as
a genetic combination of two homogeneous genotypes.One is dominant(TT) to other (tt-recessive).Result in F1 generation: 4 dominant(Tt), 0 recessive (tt)
Result in F2 generation: 3 dominant(TT, 2Tt), 1 recessive (tt)
[If one T is present then we call it Tall (Donimant effect), if none then we call it dwarf]
The results in the F2 generation after a monohybrid cross: [tex]\dfrac34[/tex] dominants and [tex]\dfrac14[/tex] recessive.
As the moon revolves around Earth, it appears to change shape. The moon goes through phases during a period that lasts about one month. Describe what causes the moon to change shape as it goes from a full moon to a last-quarter moon.
Answer:
The correct answer is - the reflected light of sunlight changes as it moves around the earth.
Explanation:
The moon appears to change its shape during the revolving around the earth. This change in the shape of the moon takes place due to the fact that the moon does not have its own light and it reflects light from back to us on the earth.
The moon changes its shape on the basis of how much-reflected light or moon we can see and how much of the moon is facing the sun.
The correct answer is - the reflected light of sunlight changes as it moves around the earth.
