Science test

The correct answer is C. Heterozygous indicates two different genes for a hereditary characteristic. D The elephant is greater in mass but is slowed less by the effects of air resistance.

Children with the genes BB will have brown hair, but none of the children have this combination of genes.

Subject Tests in Science

The brown hair gene is dominant, so it is capitalized, and because it is dominant he has brown hair. The momentum of an object is equal to the mass of the object times the velocity of the object. In order to convert Fahrenheit to Celsius, the following formula can be used: You may use your calculator.

She only has genes for red hair, so she has red hair. To test her hypothesis she is Science test to run an experiment. The endocrine system is the collection of glands that regulate metabolism, growth and development, tissue function, sexual function, reproduction, sleep and mood, among other things.

C The types of pathogens that are present in Napa Valley. Homozygous indicates two identical genes for a hereditary characteristic. C They both have an acceleration of 9.

There is no consensus among scientists as to what is causing Colony Collapse Disorder, though the USDA has undertaken a plan of action to stem the collapsing colonies involving several steps: More massive objects will only free-fall faster than smaller objects if there is a significant amount of air resistance present.

For a penny and an elephant that are free-falling in a vacuum, the rate of acceleration would be the same, so both would fall at the acceleration due to gravity which is 9.

Question 4 In the 21st century, worker bees in bee colonies have been abandoning their queens and are deserting their hives in record numbers. You can solve this type of problem by filling out a Punnett Square as shown below: B The types of parasites that are present in Napa Valley.

A A kg train car moving at mph B An kg train car moving at mph C A kg train car moving at mph D A kg train car mobbing at mph Question 18 Explanation: The genes are in lower case since they are recessive. Question 18 Which train described below would have the greatest momentum?

A The types of pesticides that are used in Napa Valley. This issue became more commonly known when The National Agriculture Statistics Service reported in that only 2.

The type of correlation between these two populations could best be described as A. In order to best support her argument that the pesticides are responsible for colony collapse, the researcher should expose the healthy bee colonies to the same pesticides used in Napa Valley.

Science: Middle School: Grades 6, 7 and 8 Quizzes

The first findings from the USDA were published inand suggested factors such as pesticides, parasites, and pathogens may be possible causes, all of which have affected hives in Northern California.

B An elephant is not a projectile, while a penny is. The correct answer is A. A Vector components of an elephant are more complex than those of a penny.

Question 19 A scientist found that when an invasive species was introduced into a river, the population of salmon native to the region decreased.

In this case, the woman has two genes for red hair bb. In this case, the man is heterozygous because he has one gene for brown hair B and one gene Science test red hair b. If she uses the same pesticides, as well as a control, and the colony exposed to the pesticide does collapse, then her hypothesis is well supported.Learn science test 1 abeka with free interactive flashcards.
