The plasma membrane primarily consists of: lipids, proteins and carbohydrates.
Answer:
7%.
Explanation:
The recombinant progeny might occur due to the exchange of genetic material between non sister chromatids known as crossing over during the meiosis.
The chromosome sequence is DABC. A and B distance is 4 map units, B and C is 2 map units, B and D is 5 map units. The distance between A and D is 1 map unit that can be calculated by subtracting the distance between BD and AB ( 5-4). The CD map distance can be calculated by adding the distance between AD, AB and BC ( 1 + 4+ 2). The recombination frequency is equal to distance between them is 7%.
Thus, the answer is 7%.
Answer: Option B
Explanation:
Myofibrils are very fine contractile fibers which extends in parallel to the columns along the length of the striated muscles fibres.
They are made of thick and thin myofilaments because of which the muscles appear striped.
The thick filaments in the muscles are composed of actin along with two other muscle protein known as tropomyosin and troponin. They help in contraction of muscles.

D) The
blue parrot population has likely increased in the last 200 years.
The answer is B. This is because the graph shows the highest number of green parrots in the 'deep forest' category of environment, whereas the numbers in the 'grassland' and 'scrub forest' are less. Since the forested area in Brazil has decreased rapidly, this means that the preferred environment of the green parrot has decreased, probably resulting in a decline in the green parrot population
