Answer:
Hydrophobic tails interact among themselves, while polar (hydrophilic) heads interact with water
Explanation:
In the first place, the polar heads of the phospholipids localized on the membrane surface interact with surrounding water molecules that also surround other cell phospholipids. Second, the non-polar tails of the phospholipids from one cell interact with molecules that repel water in the other cell phospholipid. Consequently, it forms a bilayer structure composed of two sheets of phospholipids where hydrophobic tails are arranged on the inside of the membrane, thereby allowing the interaction tail-to-tail among different cell membranes, while the polar heads of the disrupted phospholipid membranes interact together with the surrounding water.
Answer:
approximately 200
Explanation:
From the question, we have
probability of red = 0.75
Probability of white = 0.25
We are required to find the probability of 6 red + 2 white plants offspring and after we do we multiply it by 640
We will solve this using the binomial theorem method
(a+b)⁸ = a⁸+8a⁷b+28a⁶b²+56a⁵b³+70a⁴b⁴+56a³b⁵+28a²b⁶+8a¹b⁷+b⁸
The required probability is 28a⁶b²
a = 0.75
b = 0.25
= 28 x 0.75⁶ x 0.25² x 640
= 28 x 0.178 x 0.0625 x 640
= 199.36
Which is approximately 200 crosses would be needed

A mucociliary blanket to remove contaminants, secretion of lysozyme and other antimicrobial chemicals, and alveolar macrophages helps protect against airborne diseases.
Respiratory aerosols spread airborne infectious disease within infected individuals and between the infected individuals and their environment
Airborne diseases are caused by pathogenic microbes small enough to be discharged from an infected person via coughing, sneezing, laughing and close personal contact or aerosolization of the microbe. The discharged microbes remain suspended in the air on dust particles, respiratory and water droplets.
Some of the common pathogens that may spread via airborne transmission are:
Anthrax.
Aspergillosis.
Blastomycosis.
Chickenpox.
Adenovirus.
Enteroviruses.
