Bio Summative (Musk ox)

Evolution involves various mechanisms and processes that contribute to the diversity of life forms. Gene pools consist of all the alleles present in a population for a particular gene or trait, with alleles being different forms of a gene arising by mutation.

Plants

Types of plants

Colonization of land

Yes

vascular

Bryophytes

Aka mosses

Is it a seed plant

Pteridophytes

Aka ferns

Is it flowering

yes

Angiosperm

Aka flowering plant

Gymnosperm

Aka conifers

No

Algea

Aka Ulva

meitosis

Genetics

Chromosomes
X and Y
Non disjunction

Examples: Down's syndrome, Edwards syndrome,Patau syndrome , Etc

failure of a pair of homologous chromosomes to separate in meiosis I, failure of sister chromatids to separate during meiosis II, and failure of sister chromatids to separate during mitosis.

Mitosis vs meiosis

Meiosis

New cells are gametes

New cells are haploid

4 new cells

8 phases

Crossing over occurs

Mitosis

Makes diploid cells

new cells are somatic daughters

2 cells created

4 phases

Blood type

AA, Aa, BB, Bb AB, O

Traits

Recessive

Dominant

Bio diversity

Evolution

Different ways it occurs
Evedince

Embryology

focuses on early stages of cell development

Comparative anatomy

wings and fins have a very similar bone structures to hands and arms because of comparative anatomy

DNA

comparing the DNA of 2 animals

Biogeography

patterns of geographic distribution of organisms and the factors that determine those pattern

Artificial selection

Seen in someting like dogs and cats, this is a proccess of someone or something making two animals mate.

Fossils

Bones of dead animals

Gene pools

All alleles for a particular gene/trait within a population.

Alleles are one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.

Darwin theory

biological evolution by natural selection

Mechanisms of Evolution

Genetic Drift (Pinky Finger) Non Random Mating (Ring Finger) Mutation (Middle Finger) Gene Flow (Index Finger) Natural Selection (Thumb)

Natural selection

Gene flow

increase genetic diversity/variation, because new alleles that are either more rare or not present may be introduced into the population.

Mutations

it generates the genetic variation on which the evolutionary process depends.

Non random mating

Assortative mating is a mating pattern and a form of sexual selection in which individuals with similar phenotypes or genotypes mate with one another more frequently than would be expected under a random mating pattern.

founders

when a small number of individuals from a population colonize a new habitat

bottleneck

a large amount of a population is wiped out due to natural disasters or human interference.

Systems

Respatory
Pharynx
Larynx
Diaphragm
Trachea
Alveoli
Diseases

asthma, chronic obstructive pulmonary disease (COPD), lung cancer, cystic fibrosis, sleep apnea and occupational lung diseases

Bronchioles
Bronchi
Epiglottis
Nose
lungs
Digestive
Accessory Organs

Liver

filters all of the blood in the body and breaks down poisonous substances,

Pancrease

produces enzymes that help to digest food, particularly protein. The endocrine pancreas makes the hormone insulin, which helps to control blood sugar levels.

Gall bladder

Stores Bile that was produced by liver

Salivary glands

Makes saliva to break down food

GI track

Esophagus

Transports food from the mouth to the stomach using a process called peristalsis to move food

Stomach

Both mechanical and chemical digestion occur

Large intestine

Contains bacteria that help to break down waste

Small intestine

Digests food and absorbs nutrients into the blood stream via diffusion

Sections

Jejunum (second section)

Ileum (third/final section)

Duodenum (first section)

Mouth

physically breaks down food

Eats plants such as mosses, grasses sedges, forbs etc
Ciculatory
Heart

parts of heart

Aorta

pulmonary

2 pulmonary arteries

2 pulmonary vens

valves

Atrioventricular Valves

Semilunar Valve

ventricles

septum

atriums

Vena cava

Inferior vena cava

Superior vena cava

Veins
Arteries
Blood

Plasma

Carries a number of dissolved ions such as Na+, K+, and Ca2+

Protein-rich liquid in which blood cells are suspended

Platelet

When a blood vessel is broken, platelets will stick together to seal the hole so the vessel can rebuild

A cell fragment that helps the blot clot, seal wounds and stop bleeding

White blood cells

Fight disease-causing bacteria and viruses

Red blood cells

contain proteins called hemoglobin that allow them to pick up oxygen and carbon dioxide
