Bfhs Biology Chapter 1

Consumption – Ecologically, it refers to human use of natural resources. At today's high levels, it has a significant and negative impact on the environment.
Homozygous – If you're homozygous, you've got a pair of matching alleles, which are the two genes that control a particular trait.
Hydrogen bond – Weak electrostatic bond formed by the attraction of opposite charges between a hydrogen atom and an oxygen, fluorine, or nitrogen atom.
van der Waals forces – a slight attraction that develops between the oppositely charged regions of nearby molecules
dentate – if a leaf's outer edge has more pronounced teeth and they point outward the leaf has a __________ margin
kinetic energy – energy associated with motion
genetic diversity – sum total of all the different forms of genetic information carried by a specific species, or (can also refer to the sum total of all the different forms of genetic information carried by) all organisms living on Earth today
biotic factor – the living factors in an organism's environment
Prophase – The FIRST STAGE of mitosis &meiosis, characterized by shortening of chromosomes -copied DNA coils into chromosomes.
Mitosis – "Replicated chromosomes separate and move to opposite poles of the cell"… The copied DNA moves to different sides of the cell, then "cytokinesis" happens. BAM! 2 new cells.

4 phases: prophase, metaphase, anaphase, telophase

The teeth begin to break food into small pieces and are part of the ________ system.
The 3 phosphate groups in ATP are… – the key to the ATP's ability to store and release energy
Metaphase – Chromosomes line up in the middle of the cell, in between the two centrioles and the spindle
The teeth begin tо breаk fооd into smаll pieces аnd are part of the ________ system.
How is a sperm cell adapted for it's purpose? – – Many mitochondria to provide energy.
– An ACROSOME releases enzymes to digest the egg membrane.
climate – Seasonal pattern of weather conditions in an area over many years; does not change rapidly
sporophyte – diploid, or spore-producing, phase of an organism
