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

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 kind of compound would be least likely to dissolve in water

A non polar compound would be least likely to dissolve in water.

What kind of organism is used to produce human insulin

*A+*bacteria

What is the best way to show a lot of numerical data in a very small space

A data table is the best way to show a lot of numerical data in a very small place.

What term is defined as anything that has mass and takes up space

Matter Matter is the term that defines as anything that has mass and takes up space.

Matter

What describes the materials and equipment needed and procedures to follow in an experiment

The experimental protocol describes and determines materials, equipment, and procedures.

What must always happen before a hypothesis can be formed

a reveiw of what is known about the subject must occur

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 type of figure would be most useful for showing complex processes such as cell division

a diagram

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.

What type of graph or chart is used to compared relative parts of a whole

A circle graph compare parts to a whole.

What is most often displayed in pie charts-

Data for comparesment purposes and expressed in degrees of a circle which can be converted into percentages.

What is shown on the y-axis on this figure

Dependent Variable

What do most experiments tests

Predictions bases on hypotheses

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 these is always part of using the scientific method

A question about an observation

What serves as a standard of comparison to evaluate the effect of the independent variable on the dependent variable.

There cannot be one since the answer depends on the form in which the effect is measured: whether the effect is qualitative or quantitative.

There are various non-parametric measures of correlation or concordance. For data that are more quantitative there are more powerful tests such as the F-test for independent Normal distributions.

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+)
