The elements that make up rocks and minerals of solid Earth include silicon, oxygen, iron, magnesium, and other trace amounts of various elements. Living organisms are composed primarily of carbon, oxygen, and hydrogen. Other elements in living matter include calcium, nitrogen, phosphorus, potassium, and trace amounts of other elements. </span>

nydimaria [60]

Answer:

  1. guard cells
  2. monocots: evenly distributed, dicots: more dense on lower leaf
  3. Carbon dioxide

Explanation:

Stomata are pores in the leaf surface of plants. they regulate the exchange of moisture and gases in plants.  They open at night for the exchange absorption of Carbon dioxide and expulsion of Oxygen, while closing at the middle of the day to prevent evaporation of moisture or water in transpiration. These pores are opened or closed depending on the state of the two surrounding guard cells.

The somata are found on both the upper and the lower leaf surface. in dicots, the stomata are noticeably denser on the lower leaf surface, while they are evenly distributed on both leaf surfaces on monocots.

James is homozygous dominant for curly hair (cc), and his wife is heterozygous (cc). what is the probability that their first ch
daser333 [38]

The representation of the genotypes is as follows:

Homozygous dominant for curly hair (James): CC

Heterozygous dominant for curly hair (wife): Cc

The curly or straight hairs are the phenotypes and CC or Cc is the genotype of parental alleles.

When the first child is born which means the F1 generation, the type of hair the child will have can be predicted by punnet squares. The Punnet squares have been shown in the image.

From the above punnet squares, two out of four probable phenotype or genotype of curly hair is 2/4 = 1/2 or 50%, have CC as their genotype and are homozygous dominant for curly hairs.
