The major function of the placenta is

To exchange nutrients, oxygen, and waste between mother and fetus

Store food for the fetus

Cushion the fetus

Support the fertilization of the egg

White blood cells are most closely associated with which two body systems?

Circulatory and digestive

Circulatory and immune

Respiratory and nervous

Immune and digestive

A sample of DNA from a human skin cell contains 32% cytosine (C) bases. Approximately what percentage of the bases in this sample will be guanine (G)?

Anhidrosis is the inability to sweat normally. If the human body cannot sweat properly, it cannot cool itself, which is potentially harmful. Anhidrosis most directly interferes with

The synthesis of hormones

Homeostasis

The immune system response to antigens

The breakdown of water molecules

The hair color of two parents is brown. The hair color of their two children is brown. This is explained by

Natural selection

Heredity

Evolution

Environmental factors

Red food coloring is not harmful to most people, but in a small number of individuals, it causes a reaction and affects their ability to breathe. This response to the food coloring is known as

A stimulus

Natural selection

An adaptation

An allergy

Doctors sometimes use a vaccine to prepare the body to defend itself against future infections. These vaccines most often contain

Antibodies

Antibiotics

Weakened pathogens

White blood cells

Certain seaweeds contain a greater concentration of iodine inside their cells than there is in the seawater surrounding them. The energy required to maintain this concentration difference is most closely associated with the action of

Ribosomes

Vacuoles

Mitochondria

Nucleus

A certain species of plant serves as the only food for the young larvae of a particular species of butterfl y. In a large fi eld, a disease kills all the members of this plant species. As a result of the plant disease, the butterfly population will most likely

Quickly adapt to eat another type of plant

Disappear from the area

Evolve to form a new species

Enter the adult stage more quickly

When handling cat litter, humans can potentially be exposed to a harmful single-celled protozoan. Its primary host is the common domestic cat, but it can also live in humans. This protozoan is an example of a

Predator

Producer

Parasite

Scavenger

Building large manufacturing facilities can affect ecosystems by increasing the

Atmospheric quality

Biodiversity of the area

Demand for resources such as fossil fuels

Availability of space and resources

An ameba is a single-celled organism. It uses its cell membrane to obtain food from its environment, digests the food with the help of organelles called lysosomes, and uses other organelles to process the digested food. From this, we can best infer that

All single-celled organisms have lysosomes to digest food

Amebas are capable of digesting any type of food molecule

Single-celled organisms are as complex as multicellular organisms

Structures in amebas have functions similar to organs in multicellular organisms

As a way to reduce the number of cases of malaria, a human tropical disease, a specifi c DNA sequence is inserted into the reproductive cells of Anopheles mosquitoes. Which process was most likely used to alter these mosquitoes?

Cloning

Genetic engineering

Natural selection

Random mutations

Carnivorous plants, such as pitcher plants and sundews, live in bogs where many other organisms cannot. Due to the high rate of decomposition occurring in bogs, the environment is acidic and contains very little oxygen and nutrients. The bogs only support certain types of organisms because

Organisms in an environment are not limited by available energy and resources

The growth and survival of organisms depends upon specific physical conditions

Favorable gene mutations only occur when organisms live in harsh environments

Photosynthetic organisms can only inhabit environments that have a low acidity
