Answers | A+ Score Assured
To understand evolutionary relationships, we compare species. We look at
5 different types of evidence to understand how new species form, and how
life evolves over time. What are they? - 🧠 ANSWER ✔✔Fossils, Anatomy,
Embryology, Biogeography, and Molecular Biology
To understand how new species form, we talked about different barriers
that keep species apart, or force one population to diverge into two. What
are the 5 pre-zygotic barriers we discussed? What are the 3 post-zygotic
barriers we discussed? - 🧠 ANSWER ✔✔Pre-zygotic: spatial isolation,
temporal isolation, mechanical isolation, gametic isolation and behavioral
isolation.
Post-zygotic: hybrid inviability, hybrid sterility and hybrid "breakdown."
Another way new species form is via allopatric or sympatric speciation.
What do they mean? How do those types of speciation events result in new

, species forming? - 🧠 ANSWER ✔✔Allopatric- "other homelands", involves a
geographic separation of populations from a parent species and
subsequent evolution.
Sympatric- "same homeland", involves speciation occurring within a parent
species while remaining in one location.
What were the effects of salt concentration on the hatching viability of brine
shrimp? - 🧠 ANSWER ✔✔1-2% salt, or 1 2/3 tablespoon of salt per quart of
water.
What are the first and second laws of the thermodynamics? - 🧠 ANSWER
✔✔1. total amount of energy is constant and conserved. There always
been and always will be the same amount of energy. Energy can't be
created or destroyed.
2. Energy will always be lost as heat in energy transfers.
What is entropy? - 🧠 ANSWER ✔✔A measure of disorder or randomness.
