Body Temperature is maintained at through what type of energy?

The illustration shows a model of the transport of solute particles from outside the cell to inside the
Inside of cell
Protein pump
High concentration
Low concentration
Energy
Outside of cell
What type of cell transport is modeled?
A
The model illustrates active transport because energy is required for solute particles to
cross the cell membrane,
0
B. The model illustrates diffusion because solute particles are moving from an area of higher
concentration to an area of lower concentration
C. The model illustrates facilitated diffusion because protein channels allow solute particles
to cross the cell membrane.
D. The model illustrates osmosis because water molecules are moving from an area of higher
concentration to an area of lower concentration,

Compare the practices of shelterwood cutting, clearcutting, and seed-tree cutting.

ANSWER:
Clearcutting removes all the trees within a certain area at one time. Shelterwood cutting also removes all the trees in an area, but does it in stages over several years. Seed-tree cutting removes all the trees except for a select number of mature trees that can then reseed the area. Seed-tree cutting and shelterwood cutting allow for the harvested areas to recover over time without direct intervention

True or false a change in allele frequencies leads to evolution

pancreatic amylase is a digestive enzyme that digests starch in the small intestine. pancreatic amylase's optimum pH is slightly basic, which the presence of NaHCO3 provides. indicate which test tubes (1-3) would show digestion of starch following incubation. Explain why the others would not.

Tube 1 = water, starch
Tube 2 = water, starch, pancreatic amylase, HCI
Tube 3 = water, starch, pancreatic amylase, NaHCO3

How do autotrophs and heterotrophs benefit one another within an ecosystem?

A.
Autotrophs synthesize ATP and other nutrients for heterotrophs, which produce oxygen for autotrophs.
B.
Autotrophs produce oxygen and carbon dioxide for heterotrophs, which produce chemical energy for autotrophs.
C.
Autotrophs fix carbon and produce oxygen for heterotrophs, which produce carbon dioxide for autotrophs.
D.
Autotrophs transform chemical energy into radiant energy for heterotrophs, which fix carbon for autotrophs.

Autosomal Dominant Compelling Helio Ophthalmic Outburst (ACHOO) Syndrome is characterized by uncontrollable sneezing in response to the sudden exposure to bright light, typically intense sunlight. ACHOO syndrome is inherited in an autosomal dominant manner. If a heterozygous father has children with a recessive mother predict the outcome of their offspring. Using the allele (A) for dominant and (a) for recessive, identify the following using complete sentences:

Father genotype
Mother genotype
Possible offspring genotypes
Possible offspring phenotypes
Possible offspring percentage breakdown
