  • study guide notes below

  • Blooket linked as well!

Cells brainPOP due tomorrow.

Today’s agenda:

Check and Review “Intro to sexual Reproduction RaTN”

Key Notes and Concepts - fill out the companion worksheet as we discuss

  1. Sexual reproduction

    • two parents contribute genetic information to create an offspring

    • sex cells - egg and sperm (female, male)

      • each carries half of the genetic information needed

    • fertilization - process of sperm combining with egg

      • creates a zygote (a fertilized egg)

  2. Sexually reproducing organisms have two categories of cells

    • body cells (almost all cells in organism)

    • sex cells (only used for reproduction)

  3. Diploid cells

    • are body cells

      • most numerous (by far) in organism

    • have full set of genetic information

    • pairs of homologous chromosomes

      • homologous - similar genes located in similar chromosomes in same location

      • differ only in the gentic information each gene carries for its trait

        • ex. an eye color gene might have information for blue, grown, green, etc.

  4. Chromosomes

    • strings of many genes made of DNA in nucleus

    • A way to organise the DNA and its genetic information

    • found in pairs in sexually reproducing organisms

      • inherited - one from each parent

    • Each type of organism has a different number of chromosomes

      • humans - 23 pairs

      • fruit fly - 4 pars

      • dog - 39 pairs

      • fern - 63- pairs

Energy Froms and Changes: Quiz study Guide

Work:

  • tranferring energy to an object

  • caused by applying a force through some distance

  • ex. pushing a table with a force of 100N across a floor 1 meter is work.

forms of energy

potential - stored energy

  • gravitational - stored by gravity and height

  • elastic - stored by stretching/compressing certain materials

  • chemical - stored in bonds between atoms

    • foods and fuels are sources of chemical potential energy

  • nuclear - stored in the nucleus of atoms

kinetic - energy of motion

  • thermal - vibration of atoms in a substance due to temperature

  • sound - vibration of atoms in air

  • electric - flow of electric current (electrons) through wires

Mechanical - total of KE and PE in any system of parts

Radiant - light energy, electromagnetic radiation

  • light (visible, infrared, ultra violet

  • microwaves

  • X-rays

  • radiowaves, etc.

Energy Transformations

  • conversion of one form of energy into another.

  • any form of energy can be transformed into any other - though it may require more than one step.

  • Kinetic becomes potential when an object increases it’s hight and loses speed.

  • Potential becomes kinetic when an object loses height and gains speed.

Conservation of Energy

  • during any energy transformation - the total energy does not change

  • total energy before the transformation equals the total energy after the transformation

  • energy is neither created nor destroyed
