Midterm Regents Review HW

Which statement concerning sexual reproduction is correct

1. It is not necessary in order for the individual to survive

The graph below shows changes in the level of glucose in the blood of a person over a period time The graph represents the

1. maintence of dynamic equilibrium

In which process are simple materials chemically combined to form more complex materials

1. synthesis

Which activity is a function of all living cells

1. synthesis

After eating a meal, blood sugar are elevated. The body secretes hormones to help absorb excess sugar into cells and return blood sugar levels to normal. This is an example of

2. Regulation

ATP is a compound that is synthesized when

2. energy stored in chemical bonds is released during cellular respiration

The diagram below represents an activity that occurs in the human body A person exercises and body temperature increases to small blood vessels near the surface of the skin increase in diameter to body temperature decreases This diagram best illustrates

2. maintence of homeostasis

A student collected and recorded data on the response of an earthworm to varying amounts of light. The data collected would most likely provide information about earthworm

2. regulation

Which statement regarding respiration is correct

3. All living organisms carry out some form of respiration

Single celled organisms are able maintain internal stability because they

3. contain structures that perform life functions

One characteristic of all living things is what they

3. maintain internal stability

Homeostatic regulation of the body is made possible through coordination of all body systems. This coordination is achieved mainly by

3. nervous and endocrine systems

Which life activity is not required for the survival of an individual organism

3. reproduction

Photosynthesis and respiration are alike in that they both

3. require specific catalysts

Base your answers to questions 2 and 3 on the diagram below, which represents a metabolic process and on your knowledge of biology This process best represents

3. the bonding of simple sugar to form a starch molecule

Some processes that occur in a cell are listed below A. utilize energy B. detect changes in the environment C. rearrange and synthesize chemical compounds Which processes will all living organisms use to maintain homeostasis

4. A, B and C

Base your answers to questions 2 and 3 on the diagram below, which represents a metabolic process and on your knowledge of biology The letter X in the process represents

4. an enzyme

The failure of the human body to effectively maintain dynamic equilibrium can result in

4. disease

A person usually experiences small variations in body temperature over a 24 hour period. These variations in temperature are an example of

4. dynamic equilibrium

The removal of carbon dioxide and nitrogenous wastes from an organism illustrates the life function known as

4. excretion

Bumblebee show some ability to control their own body temperature. During cold weather, bumblebees have been observed warming their flight muscles by shivering. The bees are able to maintain a body temperature several degrees above that of the surrounding air. Regulation of their internal body temperature is an example

4. homeostasis

The ability to grow in size is a characteristic of living organisms. although an icicle may grow in size over time, it is considered nonliving because there is

4. no metabolic activity present

Which process is a form of a autrophic nutrition

4. photosynthesis

Prions are proteins that act as an infectious agent. They cause a variety of diseases, including "Mad cow" disease. Prions cannot produce more prions on their own, but cause the host organism to replicate more prions. Most scientists do not consider prions to be alive. A valid reason for accepting that prions are nonliving things is that

4. prions cannot carry out reproduction independently

Which life process is indicated by the arrows in the diagram of an amoeba shown below

4. transport
