Which of the following would NOT be a constituent of a plasma membrane? Select one: a. messenger RNA b. phospholipids c. glycopr
Katyanochek1 [597]

Answer:

The correct answer is a. messenger RNA

Explanation:

The plasma membrane mainly contains lipids, proteins, and carbohydrates. Phospholipids make the bilayer of the plasma membrane. Carbohydrates can be found attached to proteins and lipids.  

The carbohydrates that are attached to lipids are called phospholipids and those with proteins are called glycoproteins. mRNA is the molecule which is not the part of the plasma membrane. mRNA is produced in the nucleus through the transcription process and is responsible for proteins formation.

So phospholipids, glycolipids, and glycoproteins are the part of the plasma membrane but not messenger RNA.

Meiosis is important in reproduction because it creates genetic diversity in the population.
vagabundo [1.1K]

Answer:

True

Explanation:

Meiosis can be described as a type of cell division in which four daughter cells are produced. The number of chromosomes in each of the daughter cells formed is half the number of chromosomes of the parent.

During this type of cell division, the processes of homologous recombination and crossing over occur. During crossing over, segments of DNA are exchanged between the homologous chromosomes due to which genetic diversity occurs.

How do you think seasons occur when the moon always changes alignment with the Earth each month? What can be some factors that c
UkoKoshka [18]

Answer: The phases of the moon and the progression of Earth’s seasons are not specifically connected, but they hinge on similar processes: one astronomical body revolving around another. Both phenomena, along with the cycle of day and night, define the most intrinsic of earthly schedules.

Earth, Moon, Sun

The sun is the focus of our solar system, holding in its gravitational pull a collection of satellites that includes the nine planets. Earth, the third planet in distance from the sun, requires a little over 365 days to complete its orbit around the star. Caught in the influence of Earth’s own gravity is its moon, which takes 28 Earth days for its revolution around our planet, and is illuminated by various degrees of reflected sunlight.

Lunar Phases

During its 28-day orbital cycle, the moon rotates on its axis once, and thus presents the same face to the Earth; the “dark side” always points away from the planet. But the moon's appearance changes throughout that orbit in a succession of lunar phases, determined by the moon’s position in relation to the Earth and sun. When the Earth lies between the moon and sun, there is a “full moon." The moon reflects its maximum amount of sunlight at this time. When the opposite configuration is true--the moon is between Earth and sun--the moon is cast in shadow, manifesting as a “new moon.”
