Plant cells may generate energy through which of the following?
anaerobic respiration |
|
all of these |
|
photosynthesis |
|
aerobic respiration |
Some plant cells produce their own energy through photosynthesis which is the process by which sunlight, carbon dioxide, and water react to make sugar and oxygen. Animal cells cannot produce their own energy and, instead, generate energy when mitochondria consume outside sugar and oxygen through aerobic respiration.
The process of diffusion allows __________ to exchange oxygen, carbon dioxide, nutrients, and waste between blood and the body's cells.
capillaries |
|
veins |
|
red blood cells |
|
arteries |
Capillaries are small thin-walled vessels that permit the exchange of oxygen, carbon dioxide, nutrients, and waste between blood and the body's cells. This process of exchange is called diffusion.
The respiratory and circulatory systems are similar in that they:
deoxygenate blood |
|
transport oxygen |
|
transport nutrients |
|
add carbon dioxide |
Like the respiratory system, the circulatory system serves to transport oxygen throughout the body while removing carbon dioxide. In addition, the circulatory system transports nutrients from the digestive system.
In taxonomy, domains are the broadest classification of life. How many domains are there?
3 |
|
5 |
|
6 |
|
dozens |
The broadest classification of life splits all organisms into three groups called domains. The three domains of life are bacteria, archaea and eukaryota.
Which of the following is not a method of heat transfer?
conduction |
|
convection |
|
reflection |
|
radiation |
Heat is always transferred from warmer to cooler environments through conduction, convection, or radiation.
