Choose the correct statements about proteins and evolution. 1. Lupine leghemoglobin and human ?-hemoglobin are only about 16% identical. This is an example of convergent evolution.

2. The tertiary structure of a protein is less conserved than the primary structure.

3. Percent identity for a random alignment of two nucleic acids is likely to be higher than the percent identity for an equal-length random alignment of two polypeptide segments.

4. Paralogs are derived from a common ancestor, but often have different functions.

5. Two proteins that have similar tertiary structure are said to be homologous.

yes its like the dead sea which is full of salt which makes you stay afloat

so yes an egg will float in salt

he forelimbs below belong to four species that descended in a direct line from the ancestral mammal shown above. of the four descendants shown, which species most likely appeared earliest in evolutionary history?

protein makes up the building blocks of organs, muscles, skin, hormones and pretty much everything that matters in your body.

some choices are:

peanut butter

seeds

eggs

yogurt

meats

fish

so pretty much meat, dairy, nuts, and grains.

the earth is thought to have been formed about 4.6 billion years ago by collisions from a cloud of hydrogen, helium, rock, ice and other materials. these were pulled together by gravity to form objects in and around earth like- asteroids and small early planets called planetesimals.

so, the best possible answer to this question will be option d- to harden materials to form different parts of earth’s layers
