I NEED HELP ASP!!! A pea plant is heterozygous for both seed shape and seed color. S is the allele for the dominant,
spherical shape characteristic: s is the allele for the recessive, dented shape characteristic. Y is
the allele for the dominant, yellow color characteristic; y is the allele for the recessive, green
color characteristic. Fill in the Punnett square and tell how many offspring will be in the various
genotypes and phenotypes.

Which events are likely to be catastrophic to an ecosystem? select the three correct answers. a-hurricane. b-steady population growth. c-seasonal flooding. d-introducing of an aggressive invasive species. e-tsunami.

Mouse liver cells were homogenized and the homogenate subjected to equilibrium density-gradient centrifugation with sucrose gradients. fractions obtained from these gradients were assayed for marker molecules (i. e., molecules that are limited to specific organelles). the results of these assays are shown in the figure. the marker molecules have the following functions: cytochrome oxidase is an enzyme involved in the process by which atp is formed in the complete aerobic degradation of glucose or fatty acids; ribosomal rna forms part of the protein-synthesizing ribosomes; catalase catalyzes decomposition of hydrogen peroxide; acid phosphatase hydrolysis monophosphoric esters at acid ph; cytidylyltransferase is involved in phospholipid biosynthesis; and amino acid permease aids in transport of amino acids across membranes. a) name the marker molecule and give the number of the fraction that is most enriched for each of the following cell components: lysosomes; peroxisomes; mitochondria; plasma membrane; rough endoplasmic reticulum; smooth endoplasmic reticulum.
