Who was one of the first scientists to use numbers to look for patterns in experimental data

Gregor Mendel was one of the first scientists to use numbers to look for patterns in experimental data.
Gregor Mendel was one of the first scientists to use number to look for patterns in experimental data.

What unifying theme brought the work of Mendel and Darwin together in the big picture of biology

The discovery of DNA as the genetic material was the unified theme.

Who developed the chromosome theory of inheritance

Theodor Boveri and Walter Sutton developed the theory of chromosomal inheritance in 1902. The concept of the theory is that it identifies chromosomes as the carrier of the genetic material. It explains the Laws of Mendelian inheritance. It also states that chromosomes are linear structures with genes located at specific sites along them.

Gregor Mendel was the first doing his pea pod experiments between 1856 and 1863 and publishing his results in 1865. He is known as the father of modern genetics. His theory is called the Mendelian Inheritance, which has the following two fundamental principles:

1 - Law of segregation - two copies of a gene segregate from each other during the transmission from parent to offspring

2- Law of independent assortment - alleles of different genes assort independently of each other during gamete formation

What is formed by groups of cells which work together as organs in organ systems

Groups of cells that work together are called tissues.

What process is thought to have changed the genetic code over billions of years

evolution

What type of reproduction occurs when animals produce cloned offspring

asexual

Which kind of biologist would most likely study interactions between organisms

*A+*ecologist

How is the blueprint for life passed from parents to offspring

*A+*On a molecule called DNA

What term is defined as the ability to do work

*A+*energy

What type of scientist studies how bacteria are affected by antibiotics

*A+* micro biologist

What kind of organism is used to produce human insulin

*A+*bacteria

What kinds of organisms were missing from the first classification system

Bacteria are the kinds of organisms that were missing from the first classification system.

Which of these is found within all cells

What name is given to the process by which an organisim develops from a single cell into many kinds of cells?

What does it mean if a scientist fails to reject a hypothesis

the hypothesis has not been proven wrong.

What was the greatest step toward the discovery of cells

The greatest step toward the discovery of cells was the invention of the microscope.

What scientific breakthrough occurred around 50 years ago that helped bring all the pieces of the biology puzzle together

The discovery of the double helix structure of DNA, (the template for creating genetic offspring cells) was made in 1953 by James D. Watson and Francis Crick.

Which of these questions describes what Biff wanted to know when he asked why acacias were replacing the oaks in the park near his house

what is the mechanism.?

Suppose you have experimented to test the effects of temperature on seed germination as outlined in the study guide If you do not reject your null hypothesis what conclusion can be reached

temperature does not affect seed germination rate

While walking home from school you notice that the leaves on the trees have started to turn from green to red and yellow You wonder why this happens What should you do next

review what is known about the subject.

Do fungi make their own food or eat other organisms

They must eat other organisms because they cannot photosynthesise.

Dr. Brooke studies plants to learn about ecosystems. What is Dr. Brooke's specialty

Dr. Brooke studies plants to learn about ecosystems. What is Dr. Brooke's specialty?

What of the following is not a use for transgenic organisms

*A+* production of cloned sheep

The virus that causes chicken pox contains DNA. It reproduces inside the cells of living organisms. The virus is not made of cells and does not eat or breathe. Why isn’t the virus considered to be a living thing

it is not made of cells (A+)
