Answer:
1. directional selection
2. Hardy-Weinberg equilibrium
3. sympatric
4. This is allopatric speciation.
5. This is an example of stabilizing selection in a population because the organisms in the middle of the population have the best fitness for their environment.
6. The five conditions impacting this equilibrium are: mutations, nonrandom mating, genetic drift, migration, and natural selection.
7. Natural selection impacts single-gene traits because of the possible extinction of one trait or increase of another trait. If a trait is found to be not preferable in that environment, it could be eliminated through natural selection.
8. The total allele frequency in the Hardy-Weinberg equilibrium has to equal 1.:

Answer AND Explanation:
The cardiac muscles form the wall of the heart. The fibres are made up of many cells, which are joined end to end through intercalated discs. They have more mitochondria than skeletal and smooth muscles. Cardiac muscle is myogenic meaning that the rhythmical contraction originates from within.
Curiousity-A scientist shows interest and pays particular attentions to objects or events. He asks questions and seeks answers.
Honesty-A scientist gives a truthful report of observations. He does not withhold important information just to please himself or others.
Open-Mindedness- A scientist listens to and respects the ideas of others. He accepts criticism and changes his mind if reliable evidence contrdicts his believes.
Skepticism- A scientist bases suggestions and conclusions on evidences. When in doubt, he questions the veracity of a statement in relation to the evidences presented.
Creativity- A scientist can generate new and original ideas.
hello so the answer is suppose to be 20 words but idk but its a or b or d or c one of those :)
The alligators in the mangrove forest will receive a portion of the 500,000,000 pounds of biomass produced by the phytoplankton in the food web.
To determine how much biomass the alligators in the mangrove forest will receive, we need to follow the energy flow in the food web. Phytoplankton, as primary producers, produce 500,000,000 pounds of biomass. The energy from the phytoplankton is then passed on to primary consumers, secondary consumers, and so on. As apex predators, the alligators will receive the biomass from all the trophic levels below them. The exact amount will depend on factors such as energy transfer efficiency between trophic levels, but the alligators will receive a portion of the 500,000,000 pounds of biomass.

Unlike the endoplasmic reticulum that's involved in protein synthesis and lipid metabolism, other components such as the plasma membrane, mitochondria, and chloroplasts do different functions with varying structures, making them non-examples of the endoplasmic reticulum.
Non-examples of the endoplasmic reticulum would include other cellular components that don't have similar functions or structure. For instance, the plasma membrane serves as a barrier between the cell and its external environment, unlike the endoplasmic reticulum which involves in protein synthesis (rough ER) and lipid metabolism (smooth ER). Another non-example would be mitochondria, which are involved in cellular respiration and energy production for the cell, and the chloroplasts (in plant cells) generating energy through photosynthesis. Neither have the same functions or structures as endoplasmic reticulum.

Answer:
B. Convection currents in the mantel cause the movement of crustal plates.
Explanation:
This process is what causes plate tectonics, and doesoccurs in nature. All other options were false.
