Invasive plant species affect the interactions of living and nonliving components of an ecosystem, so the removal of invasive plants is often necessary. The goal of most plant-control methods is to disrupt or inhibit the function of different plant systems. For example, insects can be used to chew through roots in order to reduce a plant’s ability to absorb water.
Which of these functions would be most immediately affected by a reduction in water uptake by roots?
Which of these functions would be most immediately affected by a reduction in water uptake by roots?
a)
Disease resistance
b)
Seed dispersal
c)
Sunlight absorption
d)
Photosynthesis

concentrated in the roots until the plant’s reproductive tissues mature
d)
transported by the phloem to the stomata in leaves, where it attracts pollinators
3.
A student conducted an investigation to study phototropism in grasses. The only difference between the control group and the experimental group was light conditions. The control group was provided full light, while the experimental group was shaded on one side. The diagrams show the average heights and positions of blades of grass in the investigation.
Which statement best explains why the grass tips of the experimental group bent toward the light?
Which statement best explains why the grass tips of the experimental group bent toward the light?
a)

The xylem in the root system absorbed more nutrients from the shaded side.
d)
The side facing the light has a greater chance of absorbing carbon dioxide from the atmosphere.
4.

6.
Which of the following is an example of the endocrine system directly interacting with the nervous system?
a)
The vertebrae protect the spinal cord from injury.
b)
Hormones provide feedback that affects neural processing.
c)
Sensory receptors in bones send signals about body position to the brain.
d)
The brain sends signals that control the speed at which food moves through the intestines.
7.
The diagram demonstrates a feedback process involving antidiuretic hormone (ADH). ADH increases the permeability of parts of the nephrons of the kidney, resulting in less water in the urine.
This feedback loop is likely to be activated when —
This feedback loop is likely to be activated when —
a)
the body experiences dehydration
b)
blood glucose levels are stable
c)
body temperature drops
d)
the urinary tract is infected
8.
The picture shows bean-shaped glands called nodes. The clusters of cells in nodes include macrophages that break down viruses and other potentially harmful materials. Nodes also contain cells that produce protein particles capable of capturing harmful materials that flow in tissue fluid through the nodes. Different parts of the body are drained by nodes in different regions of the body.
Which body systems are directly responsible for regulating these nodes and protecting the body from harmful materials in tissue fluid?
Which body systems are directly responsible for regulating these nodes and protecting the body from harmful materials in tissue fluid?
a)
Immune and lymphatic systems
b)
Digestive and nervous systems
c)
Endocrine and digestive systems
d)
Circulatory and nervous systems
9.
The surface of the stomach is lined with epithelial cells called surface mucous cells. These cells produce a thick mucus that coats the epithelium on the inside surface of the stomach. What is the purpose of the mucous coating?
a)
It allows the epithelium to aid in the process of digestion.
b)
It causes the epithelium to expand as food enters the stomach.
c)
It protects the epithelium from the acid content of the stomach.
d)
It traps nutrients inside the epithelium as food passes through the stomach
10.
Cytokinins are a class of plant hormones that help regulate growth by promoting cell division. Cytokinins are produced mainly in meristematic tissue, where most plant growth occurs. Which system carries cytokinins produced in the roots to the rest of the plant?
a)
Vascular system
b)
Dermal system
c)
Reproductive system
d)
None of these
11.
Scientists studying illnesses caused by chemically contaminated food conduct research to minimize the effects of these diseases on society. These chemicals harm the body through interactions between the digestive system and the immune system. Scientists conducting this research are likely to describe which of these interactions between the digestive and immune systems?
a)
Chemicals enter the immune system through a break in the skin. The chemical contamination is then passed to the digestive system by the circulatory system.
b)
The immune system transforms the chemicals in the contaminated foods into harmless chemicals. These harmless chemicals are then broken down by the digestive system.
c)
When contaminated foods are eaten, the immune system prevents the chemicals from entering the digestive system.
d)
Chemicals enter the digestive system through contaminated foods. Once in the body, the chemical contaminants impair the body’s ability to fight off infectious diseases.

Plants called sundews have rounded green leaves with many hair-like structures. The ends of these structures contain enzymes in a sticky liquid that looks like nectar or moisture, as shown in the picture. The hairs do not react to dust or nonliving material but will bend inward when insects get caught in the sticky liquid. Sundews digest trapped insects over a period of a few days.

d)
Release pollen to insects and perform photosynthesis

During the final stages of human gestation, receptors for the hormone oxytocin increase on the smooth muscle cells of the uterus.
