Gas makes things buoyant, why ? And what are ways that this could be useful?
Answer:
Gas makes things buoyant by making the volume of an object lighter than the surrounding fluid it is trying to displace.
Gas Buoyancy is useful in the following ways;
• Airships
• Steel ships and
• All floating and flying vessels
Explanation:
Buoyancy is the tendency of an object to float in a fluid such as air or water. It is a phenomenon that was theorized by the mathematician, Archimedes known as the Archimedes Principle.
It states that the upward buoyant force that is exerted on a body immersed in a fluid is equal to the weight of the fluid that the body displaces.
The principle explains the reason why objects float and fly.
So, when an object is immersed in a fluid, it can float due to the upward force exerted by the fluid on the object. But for this to happen, the object has to weigh less than the fluid it is displacing.
This is where the use of a gas comes into play.
Because the object may be heavier than the surrounding fluid it is trying to displace, it is filled with a large amount of gas (usually hydrogen and/or helium) which is lighter. This makes the volume of the gas and the object put together lighter than that of the surrounding air.
This is what causes objects to float or fly

An immunodeficiency condition called bare lymphocyte syndrome is caused by a genetic defect that results in an inability to synthesize MHC class II molecules.
a. True
b. False
Answer:
True
Explanation:
This is because lymphocyte syndrome is a genetic condition where there is absence of or in ability of the cell to express histocompatibility complex class II or MHC class II and this lead to incapability of the immune system to fight infections. The immune system is compromised and weakened to fight infections.

1.Write the equation for light dependent reaction of photosynthesis
2.Write the Equation for light independent reaction of Calvin cycle?
Answer:
1. The overall chemical equation of the light-dependent reactions is given below:
12 H₂O + 12 NADP+ + 18 ADP + 18 Pi + light and chlorophyll ----> 6 O₂ + 12 NADPH + 18 ATP
2. The overall chemical equation for the light-independent reactions of the Calvin cycle is given below :
3 CO₂+ 6 NADPH + 5 H₂O + 9 ATP → glyceraldehyde-3-phosphate (G3P) + 2 H+ + 6 NADP+ + 9 ADP + 8 Pi
Explanation:
1. The light-dependent reactions convert light energy into chemical energy, producing ATP and NADPH which are used light-independent reactions to drive the synthesis of sugar molecules from inorganic CO₂ and water. Light-dependent reactions takes place in photosystem I and II. Photosystem I and Photosystem II ( PS I and PS II) are the two biochemical systems, active in chloroplasts, that serve as sites of electron transfer reactions in photosynthesis. Energy from sunlight is used to split water which releases electrons and hydrogen atoms which are transferred to NADP+ to produce ATP and NADPH and oxygen is produced as a waste product.
The overall chemical equation of the light-dependent reactions is given below:
12 H₂O + 12 NADP+ + 18 ADP + 18 Pi + light and chlorophyll ----> 6 O₂ + 12 NADPH + 18 ATP. Note that Pi refers to inorganic phosphate
2. The Calvin cycle refers to the light-independent reactions in photosynthesis. It occurs in three stages.
Stage 1 (Carbon fixation): In this first stage of the Calvin cycle, light-independent CO₂ is fixed by enzyme called ribulose bisphosphate carboxylase (RuBisCO) to ribulose bisphosphate (RuBP) to form glyceraldehyde-3-phosphate.
Stage2: ATP and NADPH are used to reduce 3-phosphoglycerate (3-PGA) into glyceraldehyde--phosphate (G3P). ATP and NADPH are used up in the process and are converted to ADP and NADP+, respectively.
Third stage: RuBP is regenerated, which enables the system to prepare for more CO2 to be fixed.
The overall chemical equation for the light-independent reactions of the Calvin cycle is given below :
3 CO₂+ 6 NADPH + 5 H₂O + 9 ATP → glyceraldehyde-3-phosphate (G3P) + 2 H+ + 6 NADP+ + 9 ADP + 8 Pi

I'm being honest the answer are in the pdf pls don't report me its not a scam
Explanation:
The correct answer is 25% of their offspring will have the same genotype as their mother.
25% of their offspring will have the same phenotype as their father.
What is genotype?The term genotype refers to an organism's whole complement of genes; in other words, it describes its genetic composition. In a more restricted meaning, the phrase can refer to the alleles, or alternative forms of a gene, that an organism carries.
what is phenotype?A phenotype is just an observable trait. Pheno means observe and is derived from the same root as "phenomenon." As a result, it's an observable sort of organism that can refer to anything from a common characteristic like height or hair color to the presence or absence of a disease.
