THIS IS A TEST. IF YOU’RE GOOD AT SCIENCE PLEASE ANSWER. IM IN THE 8TH GRADE. 1.) Which argument is correct about the growth of an organism?

A. Only genetic factors affect the growth of an organism.
B. Only environmental facts affect the growth of an organism.
C. The combination of genes and environmental factors affects the growth of an organism.
D. Genes remove factors that affect the growth of an organism.

2.) In an unstable environment where growing conditions are constantly changing, which mode of reproduction in plants provides the best chance for survival, and why?

A. Sexual reproduction; it increases the change of survival by producing many genetically identical offspring.
B. Asexual reproduction; it increases the chance of survival by introducing little genetic variation in offspring.
C. Sexual reproduction; it increases the chance of survival by introducing genetic variation in offspring.
D. Asexual reproduction; it increases the chance of survival by producing many genetically different offspring.

3.) Spermatozoa and ovum are specialized cells that contain half the number of chromosomes from both parents. The spermatozoa and ovum combine chromosomes to create a fertilized egg with a full set of chromosomes. Which process creates spermatozoa and ovum?

A. cell differentiation
B. cell growth
C. meiosis
D. mitosis

4.) Students prepare for a debate about genetic engineering. Which statement supports the students’ argument for how genetic engineering may cause ethical concerns?

A. Genetic engineering can decrease the nutrients in plants.
B. Genetic engineering can cause harm to animals during tests.
C. Genetic engineering can provide cures for inherited disorders.
D. Genetic engineering can decrease the use of pesticides in crops.

5.) Which explanation best identifies the relationship between mitosis and reproduction?

A. Mitosis is a form of sexual reproduction because the daughter cells form from one single parent cell.
B. Mitosis is a form of sexual reproduction because the daughter cells are genetically different from the parent cell.
C. Mitosis is a form of asexual reproduction because the daughter cells form a new nuclear membrane after reproduction.
D. Mitosis is a form of asexual reproduction because the daughter cells are genetically identical to the parent cell.

Interpret the model. a three-part model with black right-arrows between the parts. left part: a large green apple-shaped component with a w-shaped indentation centered on top. a small blue apple-slice shape sits above the left indentation and an arrow points from the shape to the indentation. a small purple apple-slice shape and arrow sit above the right indentation and an arrow points from the shape to the indentation. middle part: a large green apple-shaped component with a square indentation centered on top. sitting in the left side of the indentation is a blue apple-slice shape with a flat bottom, fused to a purple apple-slice shape with a flat bottom on the right side of the indentation. right part: a large green apple-shaped component with a w-shaped indentation centered on top. an up-arrow is centered above the indentation pointing to a fused blue and purple apple-slice-shaped flat-bottom component sitting above the indentation. assigne "true" or "false" to the end of each statement. the model shows a shape change occurring in the enzyme after the substrate is bound in the active site. t/fthere are two products in this model. t? f there are three substrates in this model. t/f the model shows two different enzymes. t/f
