Answer:
The animal cells produce the collagen but the plant cell does not produce collagen that responsible for producing the complex structure of protein and carbohydrates that is called extracellular matrix cell. Collagen is an important protein that provides strength to the structural integrity. On the other hand, the plant has not collagen so they have their extracellular supportive structure. The cell wall is so rigid and covered by the cell that protects it that provides shape and support to it. The plant cell also made up of molecules and these are called cellulose. These cellulose structured into the fibers that are called micro-fibrils
Cohesion is the term for molecules of a substance sticking together. One of the most common examples is water beading up on a hydrophobic surface. ... Because the water molecules' positive and negative charges are attracted to the positive and negative charges in the cellulose molecules in the paper.
Answer:
The question is somehow not correct, it suppose to be what is the MASS of an object that needs a force 4500N to accelerate it at a rate of 5 m/s as gotten from another website.
The correct answer is 900kg.
Explanation:
To get the mass of the object use the formula
F=Ma
Where F is force
M is mass
a is acceleration.
F= 4500, M=? a=5m/s
4500= M× 5
M=4500/5
M=900kg
Mass is in kg
Answer: Oxygen atom has 8 Protons
Explanation:
Oxygen atom (O) has an atomic number of 8, and a mass number of 16.
Recall that atomic number of any element is equal to the number of protons in its electronic shell, hence, the number of protons in oxygen atom is also 8
Answer:
Explanation:
the purple allele (C) is dominant to the pink allele (c).
The frequency of C represents p while that of c represent q. Using the formula p+q= 1
The proportion of pink flower is 153/1000 = 0.153. This is also the frequency of the genotype cc (q^2).
Thud to find q which is the frequency of the c allele,
q = √0.153
q = 0.3912
From the formula p +q = 1 we can find p p = 1 - 0.3912
p which is the frequency of the C allele
p = 0.6088.
B. the proportion of all purple flowering plants that are heterozygotes and homozygotes is 847 / 1000 = 0.847
