Answer:
what diagram are u talking about
The best phrase is 'natural selection is a process that causes evolution '. Natural selection can also be referred to as selection pressures within a population that favour particular traits that enable the population to better adapt to its habitat. It's could be better camouflage, high sense of smell, and etcetera. These traits are preserved while those that cause disadvantage are diminished. This causes evolution of the population .
D i think is the answer most of all
Answer:
I'd say C, The main different between cellulose, and starch is the function they preform in plants.
Explanation:
I've done some research to find that starch and cellulose do compose of different parts of the plant, and that starch repeats glucose units oriented in the same direction, while cellulose repeats glucose units 180° around the axis of the polymer backbone chain. Of course we know photosynthesis produces glucose, and oxygen from co2, light energy, and h20. Which means that they both have the same monomer. Since cellulose and starch are polymers of the monomer glucose, A can't be right. They are said to have the same size because the only difference is how the repeat of the glucose monomers are oriented differently so this does not exactly change its relative size, so B can't be right. Starch has alpha linkages while Cellulose has beta linkages. This means they have a different structure which can affect the function. Also, the function of cellulose is a Structural polysaccharide(cause it is part of the walls of the plant), while starch is a Storage polysaccharide (cause sugar=energy).
Answer:
Explanation:
A diploid cell becomes haploid during Meiosis I and is completed after Telephase I. These homologous chromosomes (from mom & dad, all duplicated) pair up during prophase I forming tetrads. The pairs of homologs line up on the metaphase plate during metaphase I
At what stage of meiosis are cells haploid?
Prophase II: Starting cells are the haploid cells made in meiosis I. Chromosomes condense. Metaphase II: Chromosomes line up at the metaphase plate. Anaphase II: Sister chromatids separate to opposite ends of the cell. Telophase II: Newly forming gametes are haploid, and each chromosome now has just one chromatid
