Answer:

a. shorten

Explanation:

Inability or failure for joints to move through their entire range of motion is caused by constrictions. These constrictions often results when the excess adipose tissues that surrounds the muscles and ligaments are not in required adequate proportion. These constrictions can be caused by ageing, fatigue, muscular diseases etc. As a result of these constriction in the joints, let say for example, the knee joint, the muscle and ligaments tends to shorten in length.

Setler [38]

Answer:

The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material found in all living organisms, ranging from single-celled bacteria to multicellular mammals. It is found in the nucleus of eukaryotes and in the organelles, chloroplasts, and mitochondria.

Which is a product of the light reaction?
elena-s [515]

Answer: NADPH and ATP

Explanation:

The mechanism of photosynthesis can be divided into two phases, light reaction, and carbon fixation. During the light reaction, photosynthetic pigments absorb radiant energy and undergo a series of photochemical reactions and convert the trapped energy into chemical energy which is stored in the form of NADPH and ATP. These two compounds constitute the assimilatory power. Light reaction is light dependent and it takes place in the grana of the chloroplast.

Explain Mendel's law of independent assortment and how the 9:3:3:1 phenotypic ratio among the F2 of a dihybrid cross provides ev
GrogVix [38]

Answer:

Explanation:

Mendel's law of independent assortment state that two different genes assort independently in gamete formation.

To reach this conclusion, one has to do a dihybrid cross. This means that two genes responsible for different traits need to be analyzed at the same time.

1) Starting with a <u>parental generation of a cross between two pure lines</u> (homozygous for both genes) <u>with different traits</u>, a plant with yellow and round seeds (YYRR) and another with green and wrinkled seeds (yyrr). <u>The F1 will be phenotypically homogeneous (</u>yellow and round)<u>, and genotypically heterozygous (</u><u>YyRr</u><u>)</u>.

2) If the individuals from the F1 are crossed with one another,  we have to do a Punnett Square to determine the phenotypic ratio of the F2.

  • If the genes assort independently, the F1 individuals will produce their different gametes with the same probability. Each possible gamete will appear in a 1/4 proportion: YR, Yr, yR, yr.
  • The 9:3:3:1 ratio is a result of analyzing the possible phenotypes that result from the dihybrid cross.

See the attached image for an illustration of the crosses in each generation and the Punnett Square.
