Can the environment and the heritage be used to describe evolution?

Evolution is caused by genetic mutations that become favorable for survival.

For example if a bird has a mutation that gives it a longer beak and it lives in an environment in which a longer beak lets the bird catch more food- the longer beak becomes a favorable trait.

Now the bird is able to survive “better” thus it lives longer(due to its ability to catch more food). Because of this it reproduces more and passes the trait on to its offspring.
Overtime this mutation takes over the population of birds in the area.

How can speciation happen between two separate populations?

algol [13]

Speciation is the evolutionary process by which biological populations evolve to become distinct species. The biologist Orator F. Cook coined the term 'speciation' in 1906 for the splitting of lineages or "cladogenesis," as opposed to "anagenesis" or "phyletic evolution" within lineages.

explain how having a haploid number of chromosomes contributes to the function of gametes in a life cycle

kotegsom [21]

Having the haploid number of chromosomes allows the zygote to have the correct number. If gametes weren't haploid, every generation of organisms would have twice as many chromosomes as their parents. I hope my answer has come to your help. God bless and have a nice day ahead!

In your own words, give a brief overview of the process of photosynthesis. Include where each phase place within a plant cell.

vodka [1.7K]

Answer:

Photosynthesis has two parts: the light-dependent reactions and the dark reactions (the Calvin cycle). Photosynthesis in a general sense, uses CO2 and water to create C6H12O6 (glucose) and oxygen. The light-dependent reactions use water to make oxygen, and a reduced energy carrier (NADPH) is also created. The Calvin cycle uses carbon dioxide and ATP to create G3P for glucose.

The light-dependent reactions occur on the membrane of the thylakoid and also involve shuttling electrons across different complexes (photosystem II and photosystem I), eventually causing ATP to be created with a proton gradient.

The light-independent reactions/Calvin cycle occur in the stroma of the chloroplast and also involve shuffling carbons around. Carbon dioxide is processed in three stages, and glucose is made from 6 CO2.
