Answer:
B. Heterotrophs cannot create their own food
Explanation:
Autotrophs, on the other hand, can.
Answer:
- An ecosystem consists of a community of organisms together with their physical environment.
- Ecosystems can be of different sizes and can be marine, aquatic, or terrestrial. Broad categories of terrestrial ecosystems are called biomes.
- In ecosystems, both matter and energy are conserved. Energy flows through the system—usually from light to heat—while matter is recycled.
- Ecosystems with higher biodiversity tend to be more stable with greater resistance and resilience in the face of disturbances, or disruptive events.
Habitats
Habitat is the place where an organism resides. Habitat is of different types such as terrestrial habitat, marine habitat, Estuarine habitat, freshwater habitat.
Answer:
A genotype is the genetic alleles (combined one from each parent), and phenotype is the physical appearance of said trait.
Explanation:
With peas—
YY is the genotype
Yellow peas in the phenotype
Answer:G protein action
Explanation:
Signal transduction through protein action is through G protein coupled receptors (GPCR). Binding of different types of signal molecules to G protein couple receptors is a general mechanism of signal transduction.
G proteins act as an intermediary to a stimulation of a receptor. When an extracellular messenger, the hormone (H) combines with the specific receptor (R) on the plasma membrane. The H-R complex activates the regulatory components of G proteins. The G-protein inturn will interact with the effect proteins which may be enzymes or ion channel proteins, which result in the desired effect.
