Answer:cell 9 is not missing any organelles compared to cell 1.
Cell 2 would not function normally because it lacks the mitochondria which is the powerhouse necessary for energy production & hence growth & survival.
Cells 4 & 7 lack the rough endoplasmic reticulum responsible for protein formation hence amino acids which are the building blocks of life will not be produced.

Answer:
The correct answer is- Immune system
Explanation:
There are physical, chemical and immunological barriers present in our body which helps us to protect from the foreign antigen. They all assist each other and helps in pathogen removal from our body.
The physical barrier includes skin, gastrointestinal tract, respiratory tract, etc which do not allow the microbe to enter the body. Chemical barriers include tear, saliva, acid in the stomach which kills microbes on the body surface.
Immune cells like macrophages, B cells kills microbes when it gets in the body. Lymphatic system also contain immune cells and helps in microbe removal.
So the immune system is assisted by physical barrier, chemical barrier, and lymphatic system.
Answer: water potential is the measure of the energy of water to move from one area to another.
Explanation: water potential effects osmosis in a way that water needs to move through membrane and for this movement it requires pressure which makes water potential high so water movement will be faster across the membrane. Water potential determines water movement in osmosis that water move from high water potential region to low water potential region. If water potential is high inside than outside, then water movement to outside will be more.
If water potential is high outside than inside then water will move more inside. If water potential is the same in and outside then water movement inside and outside will be same and this will be called as equilibrium.
Answer:
9/16
Explanation:
Let broad, straight wings be represented by the allele W. Homozygous condition will be WW or ww while heterozygous condition will be Ww
Let pale-colored body with dark transverse stripes is represented by C. Homozygous condition will be CC or cc while heterozygous condition will be Cc.
Heterozygous condition for both trait will be WwCc. Hence a mating between two flies that are heterozygous for both trait will be;
WwCc x WwCc
This will yield offspring in the following phenotypic ratio;
Broad, straight wings with pale-colored body/dark transverse stripes - 9/16
Broad, straight wings with ebony body colour - 3/16
Nubby, vestigial wings with pale-colored body/dark transverse stripes - 3/16
Nubby, vestigial wings with ebony body colour - 1/16.
See the attached image for the Punnet square result of the cross.
The proportion is 9/16
