WHAT IS END SYSTOLIC VOLUME

The end-systolic volume is the amount of blood in your heart’s ventricles at the very end before it begins to relax and fill up with air during diastole.

WHAT IS PRELOAD IN THE HEART

Preload is the pressure that’s in your heart before you contraction. It comes from venous return, which means it can be considered “filled” or full of blood already since all its contents were drained into one area first (the lungs).

WHY ARE GAP JUNCTIONS A VITAL PART OF THE INTERCELLULAR CONNECTION OF CARDIAC MUSCLES?

Gap junctions are key to the electrical signal spreading throughout our bodies. They allow an action potential from one cell, which then makes it easier for other cells nearby be activated as well because they’re now receiving that same message!

WHICH OF THE FOLLOWING DESCRIBES THE MOST LIKELY ORDER OF EVENTS IN ALLOPATRIC SPECIATION?

Genes are thebuilding blocks of life. They help organisms grow and evolve, but traits can also get lost or changed over time due to genetic drift (which means that individuals carry different genes) as well as isolation via geographic separation into races like black Ability Europe versus white Ability America; this leads us back towards Convergence again where all these unique features combine together in a population creating diversity within it’s own kind!

HOW DOES REPRODUCTIVE ISOLATION INCREASE DIVERSITY

The reproductive isolation can be best studied in Asian elephants. Isolated from each other by geographic location, these populations have stopped breeding and evolving into a single species with diversity already bred-in!

WHAT IS THE THEORY OF ISLAND BIOGEOGRAPHY

The equilibrium theory of island biogeography (ETIB) provides some predictions about how various characteristics of green spaces such as their area, shape and level of isolation should influence species richness.

WHAT PREVENTS SPECIATION FROM OCCURRING IN SYMPATRIC POPULATIONS

A habitat is an environment that organisms require in order to live. However, some populations of the same species may have enough overlap with each other and occupy one common area without any physical barriers between them – this means they’re not segregated by geographic location like mountains or oceans; rather it’s more likely because there isn’t space for all members within their range than anything else! If animals from different subpopulations continue mating at random throughout time then sympatric speciation won’t occur
A population refers both genetic variations due geographical isolation as well

WHICH BEST DESCRIBES BIOGEOGRAPHIC ISOLATION?

Biogeographic isolation is a natural process that can occur when two populations of the same species are isolated due to physical factors. This means they live in different areas and have no contact with each other, which leads them away from hybridizing or exchanging genes as much because their DNA evolves differently depending on where it’s located within an area’s ecosystem
