The total net force acting on the rope is 120 because 300 - 180 = 120.
Remember that a biotic factor is a living component in an ecosystem that affects the population of another organism. So that means that the answer is B.
<span><span>The correct answer is </span>b. LH.</span>
Luteinizing hormone (LH) is a pituitary hormone with the influence on both, male and female reproductive system, regulated by gonadotropin-releasing hormone (GnRH). In males, LH acts upon the interstitial cells (or Leydig cells) of the testis, which produce testosterone. LH regulates the expression of the enzyme that is used to convert the precursor of the testosterone to testosterone.
The correct answer is C. Sphagnum moss
Explanation:
In biology, a renewable source of energy refers to a type of source that replenishes and therefore can be widely used to obtain energy such as wind energy or solar energy that are almost always available. On the other hand, a seedless plant is a type of plant that does not have seed and because of this, they reproduce through sperms.
All fo the plants listed (club moss, horsetail, fern and sphagnum moss) belong to the category of seedless plants; however, from this, the only one that has been widely used a source of energy is sphagnum moss because dried sphagnum moss or peat moss is used as carbon or coals source and therefore is useful for heating building and because it is a plant that grows extensively it is also a renewable source.
The different phenotypes expected are 1:2:1:2:4:2:1:2:1
<u>Explanation:</u>
Cross between AbBb X AbBb
F1 generation : AbBb
Zygotes – AB , Ab , aB , ab
F2 generation:
Genotype of the individuals from the cross = 1:2:1:2:4:2:1:2:1
