Life Science


Four major chemical organic compounds in all living things

Four major chemical/organic compounds in all living things

  • 1.carbohydrates

  • 2.lipids

  • 3.proteins

  • 4.nucleic acids


Cell biology molecular biology

Cell Biology (molecular biology)

  • What are the basic building blocks of life?

  • Functions:

    • 1. DNA: deoxyribonucleic acid – genetic instructions, usually double

    • 2. RNA: ribonucleic acid – genetic instructions, single stranded


Protein synthesis

Protein Synthesis

  • Transcription:

    Occurs in nucleus writes DNA to RNA

  • Translation:

  • Occurs outside the nucleus and transcribes the mRNA to tRNA & codons (proteins)

Components & Functions

  • Components & Functions


Temperature conversions

Temperature Conversions

  • [°C] = ([°F] - 32) × 5/9

  • [°F] = [°C] × 9/5 + 32

  • Kelvin = [°C] + 273


Mitosis cell splitting in eu kary otic

Mitosis: cell splitting in eu/kary/otic


Meiosis cell division for sexual reproduction

Meiosis: Cell division for sexual reproduction


Mitosis vs meiosis

Mitosis vs. Meiosis

  • Mitosis/Meiosis

Life span of cells

Life Span of cells

  • Bacteria

  • Red blood cells

  • Stem cells

  • Bacteria spore


Level of hierarchy in organisms

Level of Hierarchy in organisms

  • Cell

  • Tissue

  • Organ

  • Organ system

  • organism


Anatomy main body systems

Anatomy: Main body systems


Anatomy body systems

Anatomy: Body Systems


1 muscular system

1. Muscular System

  • Function:

    MOVEMENT!

  • Voluntary: arms move

  • Involuntary: stomach, heart

  • Skeletal: help body to move

  • Smooth: help organs move

  • Cardiac: heart


Skeletal system

Skeletal System

  • Function: Support, movement, protects organs

  • Bones:

  • Ligaments

  • Tendons


Nervous system

Nervous System

  • Sends messages throughout body

  • CNS: Brain and spinal cord

  • PNS: nerves that go off the CNS


5 senses

5 senses

  • Sight

  • Hearing

  • Touch

  • Taste

  • Smell


Endocrine system

Endocrine System

  • Sends messages throughout the body

  • Organs: kidney, pancreas, brain

  • Glands: release hormones (Thyroid gland, pituitary gland)

  • Hormones: chemicals that send messages, triggers changes (growth, metabolism) (HGH)


Circulatory system

Circulatory System

  • Body’s transport system: blood, hormones, O2

  • Heart: pumps blood

  • Veins, arteries, capillaries

  • lungs


Lymphatic system

Lymphatic System

  • Defense system

  • Lymph nodes

  • White blood cells


Respiratory system

Respiratory System

  • Exchanges O2 and CO2

  • nose

  • Trachea

  • Bronchial tubes

  • Lungs

  • Alveoli sacs


Digestive system

Digestive System

  • Breaks down food for energy

  • Mouth and saliva (chewing)

  • Esophagus

  • Stomach (breaks down food with acids)

  • Intestines (absorption)

  • Anus (waste)


Urinary system

Urinary System

  • Eliminate toxins and wastes

  • Kidneys (filter)

  • Ureters (transport)

  • Urinary bladder

  • Urethra (gets rid of waste)


Reproductive system

Reproductive System

  • Allows humans to reproduce

  • Male: Sperm, testes

  • Female: egg (ovum), uterus

  • Lots of hormones involved with this system (testosterone, estrogen…)


Integumentary system

Integumentary System

  • Protection

  • Skin – largest organ


Teeth

Teeth

  • Chewing, speaking, health – 32 teeth total

  • 2 sets of teeth:

    • 1.

    • 2.

  • Types of Teeth

  • Incisors: 8

  • Canines/cuspids: 4

  • Premolars: 8

  • Molars: 8

  • Third Molars: 4*


Vitamins nutrients

Vitamins & Nutrients

  • ______________: when the body cannot synthesize enough of the nutrient that it requires it from its diet

  • ______________: come from the earth

  • Classified for what they do

  • Vitamin A/carotenoids: vision, bone growth, repro, cell division, immune system (liver, beef, milk, carrots, spinach)

  • Vitamin B2/riboflavin: body growth, repro, RBC

  • Vitamin B6: metabolism, catalyst & rxns, energy (beef, liver, starches, fruit (not citrus)

  • Vitamin B12:required for RBC formation, neuron formation and DNA synthesis(fish, meat, poultry, eggs, milk)

  • Folic Acid (B9 vitamin): growth

  • Vitamin C: antioxidant, antiviral agent (citrus, broccoli, chestnuts

  • Vitamin D: calcium absorption, bone growth/strength (comes from the sun and some foods – fish and some dairy)

  • Vitamin E: antioxidant, fat decomposition, immune (nuts, seeds, oils, leafy greens)

  • Vitamin K: Blood clotting, regulates blood calcium levels (avocado, berries, greens, nuts)

Antibiotics

AntiBiotics

  • Anti/bios: against/life

  • Drugs to treat infections caused by ______________

  • TB

  • Penicillin

  • Kills bacteria and stops them from multiplying

  • Not effective with ______________.


Ecosystem

Ecosystem

  • Biotic and abiotic (living and non living) that make up a biological environment

Sym biotic relationships

Sym/biotic Relationships

  • Mutualism: both members mutually benefit

  • Commensalism: one benefits while the other is unaffected

  • Parasitism: one benefits at the expense of the other (host)

  • symbiotic examples
