Examples of Asexual Reproduction Include Budding Binary fission

Examples of Asexual Reproduction Include: Budding Binary fission Regeneration

Do runners create offspring with the same or different traits as the parent plant?

This lizard has the ability to re-grow his tail. What is this process called?

When sperm and egg join, what type of reproduction is it?

GS EG

With frogs, the female discharges eggs – usually into water – while the male sheds sperm over the eggs.

Complete flower: contains both male AND female structures, and can selfpollinate. Imperfect/Incomplete flower: has ONLY male OR female structures and must crosspollinate. Pollination: the transfer of pollen from the anther to the stigma. The pollen travels down through the style to fertilize ovules in the ovary at the bottom of the pistil.

1. Which flower can pollinate itself? 2. Which flower can only make pollen? 3. Which flower can only produce eggs? 4. Which flowers can cross pollinate?

The function of the reproductive system is to produce gametes (sex cells): egg in females, sperm in males; each containing 23 chromosomes to pass on to new offspring!

What are these karyotypes showing?

Gregor Mendel is known as the “Father of Genetics” because he performed the first tests on traits passing from parents to offspring. Why would it be important for Mendel to have tried his experiment many times before reporting his results to the scientific community?

Dominant traits are represented with letters called Alleles. Which alleles in each gene pair represent dominant traits?

Which genotypes below represent offspring that will show a dominant phenotype for a trait?

BB, Bb = Brown eyes bb = blue eyes

WW, Ww = Widow’s Peak ww = straight hairline

Recessive traits are represented with letters called Alleles. Which alleles in each gene pair represent recessive traits?

Which genotypes below represent offspring that will show a recessive phenotype for a trait?

DD, Dd =dark hair dd = light hair

What is the chance that more offspring will have blue eyes? ? B b b Bb bb 50% Bb Homozygous recessive Heterozygous dominant Phenotype = blue Phenotype = brown

The Bowling plant is a rare plant that grows in the desert, and is able to survive in extreme heat and low moisture. How would the genes of this plant be beneficial to corn plants grown in the grasslands of Africa? (purebred) The genes from the Bowling plant can be cross-bred into the corn plants to help them grow more efficiently in the dry, hot grasslands of Africa.

Mechanical digestion: Chemical digestion: food is chewed, mixed, churned (teeth, tongue, stomach) chemical reactions break down food into small molecules (saliva, digestive juices, stomach, bile, liver, gall bladder) Chemical energy from food is transferred into thermal energy in your muscles as you move.

A rock was thrown at the side of the building from students who were playing outside. The rock hit the window and cracked it. What should the students inside the classroom do first?

Your central nervous system is made up of what structures? What is the function of your nervous system?

The urinary system filters liquid wastes out of your blood through the kidneys to produce urine. Urinary System

Excretory System: the systems of the body that function together to eliminate wastes from the body. Digestive system Gets rid of undigested food wastes (feces) Integumentary (skin) – gets rid of salts and water (sweat) Respiratory system gets rid of carbon dioxide gas and water vapor Urinary system gets rid of excess water and cell wastes (urine)

Integumentary system – SKIN – protects internal organs, protects body from microscopic organisms, regulates temperature and eliminates wastes through sweating.

Circulatory System – heart, blood vessels – transport materials to and from every body cell.

Natural Selection and Evolution

Newton’s 1 st Law of Motion An object at rest will remain at rest, or an object in motion will remain in motion UNTIL a force acts upon it. (Inertia) Friction: a force that opposes motion Newton’s 2 nd Law of Motion A change in motion occurs only if a net force is exerted on an object. F = ma (force = mass x acceleration) It takes more force to move an object with more mass, an object with more mass has more force. Newton’s 3 rd Law of Motion For every action there is an equal and opposite reaction.

Force - A push or a pull Balanced force: Unbalanced Force: When 2 or more forces act upon an object and NO motion occurs When 2 or more forces act upon an object, one force is greater and movement occurs.

Net force is measured in Newtons (N). What is the net force for each example? 20 N A 20 N 10 N C 40 N 60 N B

Space Suits Provide: • proper oxygen • proper air pressure • proper temperature • communication • protection from space junk • protection from the sun and all ultraviolet rays

How is the space shuttle able to travel out of our atmosphere to orbit in space?

What force keeps the shuttle in orbit around Earth?

Characteristics of our solar system that allow life to exist • presence of water • 21% oxygen in atmosphere • distance from the sun
