1st, 3rd, 5th
Um the brainliest answer would be appreciated greatly :)
Answer:
Hydrophilic heads facing exterior
Hydrophobic tails facing interior
Explanation:
In 1972, the fluid mosaic model was proposed to describe the structure of the plasma membrane. This model describes the plasma membrane to possess components including phospholipids, cholesterol and proteins. The phospholipid component is composed of glycerol, two fatty acids and a phosphate-containing head, which are arranged in two adjacent layers forming the phospholipid bilayer in the membrane of biological organisms.
Phospholipids have both the hydrophilic and hydrophobic region. Hence they are said to be AMPHIPATHIC.
The head of the phospholipid is negatively charged due to its phosphate content, making it polar and hydrophilic i.e. water-loving. This hydrophilic head faces the exterior of the cell in order to interact with fluids.
The tails of the phospholipid are long fatty acids that keep away from water i.e. hydrophobic. Due to their water-fearing nature, they avoid water and face the interior of the cell, where each tail face each other.
Answer:
the answer is differences in heating = C
Explanation:
Answer:
XbY
Explanation:
The gene responsible for colorblindness is written as Xb since it is present on the X chromosome. In humans, sons get their X chromosomes from the mother while inheriting the Y chromosome from the father. In the given cross, the genotype of the colorblind mother would be XbXb (the X-linked recessive traits such as colorblindness are expressed in homozygous conditions in females).
She would transmit one copy of "Xb" to her son. The genotype of the father would be "XY" and he will give "Y chromosome" to the son. Therefore, the genotype of the son would be "XbY".
Answer:
C. IBIB
D. IBiO
Explanation:
The blood group system comprises of three different kind of alleles, iA, iB, IO. As we know that a person gets two alleles for both traits, one from father and one from mother, and based on that a person gets its blood group. IA and IB are dominant to IO.
So, if a person has genotype IAIO he will have blood group A and if he has genotype IOIB he will have blood group B because A or B are dominant to O.
However, if a person has blood group O it means that he has genotype IOIO.
So, in this diagram we see that Eric has blood type O, which means that his genotype will be IOIO.
The Eric's mother Melissa has blood group B, which means that she can either had genotype IOIB and IBIB respectively.
Similarly, Eric's grandmother Tricia has genotype B which means that she can have genotype both IOIB and IBIB respectively.
Therefore, both C and D are correct options.
