What is a global climate model?
marusya05 [52]

Answer:

What is a Global Climate Model? A global climate model (GCM) is a complex mathematical representation of the major climate system components (atmosphere, land surface, ocean, and sea ice), and their interactions. Earth's energy balance between the four components is the key to long-term climate prediction.

Lena [83]

Answer:

No, observed and expected frequencies are different.

Observed frequencies: p2 = 0.56 , 2pq = 0.375, q2 = 0.062

Expected frequencies: p2 = 0.774 , 2pq = 0.211, q2 = 0.014

Explanation:

Given frequency of recessive genotype (q2)= 14/ 1006 = 0.0139

Frequency of recessive allele s (q) = square root of 0.0139 = 0.12

Frequency of dominant allele S (p) = 1-q = 1-0.12 = 0.88

Expected frequency of homozygous recessive genotype = 0.12 x 0.12 = 0.014

Expected frequency of homozygous dominant genotype = 0.88 x 0.88 = 0.774

Expected frequency of heterozygous dominant genotype = 2pq = 2 x 0.88 x 0.12 = 0.211

Observed frequencies in population 2

Observed frequency of homozygous dominant genotype = 308 / 549 =0.56

Observed frequency of heterozygous dominant genotype = 206 / 549 =0.375

Observed frequency of homozygous recessive genotype = 34 / 549 =0.062

Observed frequencies do not match with expected frequencies.

Which organelle contains digestive enzymes that break down waste material and debris in the cell? lysosome ribosome vacuole chlo
Leto [7]

Answer: Lysosomes.

Lysosomes are the specialized membrane-bound cell organelles present in almost all eukaryotic cells. The lysosomal membrane keeps the acidic (pH 5) compartment of lysosomes segregated from the cytoplasm. Lysosomes play a crucial role in the degradation of waste material and debris inside the cell.

This is accomplished by the action of hydrolytic enzymes also called as acid hydrolases. These enzymes are only active in the acidic medium which is maintained in the lysosomes by proton pumps.

Lysosomes are also called as 'suicide bags' as they clear off the waste material.
