Answer:
Combined decrease in sarcomere length.
Explanation:
Sarcomere is the functional unit of the striated muscle tissue. The units get repeated between the two Z lines. The striation under the microscope is shown by the sarcomere.
Actin and myosin protein plays an important role in the muscle contraction. The individual length of the thick (myosin) and thin (actin) filament do not changes and slide over one other. But the sarcomere overall length decreases that result in muscle contraction.
Thus, the answer is combined decrease in sarcomere length.
Answer:
100% EE, 100% red eyes
Explanation:
For an organism, the genotype refers to the genetic characteristics of the organism while the phenotype refers to the physical characteristics of the organism.
The red eyes (E) is dominant while the white eyes (e) is recessive.
Since both parents are EE, the genotype of their offsprings would be EE, EE, EE, EE
That is: EE × EE = EE, EE, EE, EE
Hence the genotype is 100% EE.
Also, the phenotype is 100 red eyes.
The development of seeds are considered to one of the most important in the evolution of land plants especially the spore-bearing vascular plants. The seeds will serve as the alternative means of dispersal for reproduction purposes especially in areas where there is no water.
Answer:
b) The solar radiation can be absorbed by clouds and the atmosphere
Explanation:
The clouds consist of water vapour and the atmosphere consists of mixture of ai for example the carbon dioxide and methane. The water vapour and these two gases can all absorb sunlight. Reason for this is that the bonding pairs of electrons come from different atoms in the molecule and the bonds are distorted. Symmetrical molecules but with distorted bonds or bond electron pairs.
