AG Flashcards
The inherent inclination of an organism toward a certain behavior
Instinct
Protozoans difder from algae primarily in the way in which they carry on ______
Food getting
The nitrogen-fixing bacteria found on leguminous plants make possible the synthesis of _____
Protein
The cell formed as the result of fussion of an egg cell and sperm cell
Zygote
Immediately after a frightening experience, a person’s blood is likely to show higher than normal concentrations of ______
Hormones
The two processes mainly responsible for the transpo of materials upward through the conducting tubes of plants are
Diffusion and Capillary action
Bacteria usually reproduce by the process of?
Fission
Environmental factors that cause organisms to respond are called?
Stimuli
The process of culturing bacteria by providing them w the necessary conditions for growth
Incubation
If a trait skips a generation, the most probable reason is that it ________
Is recessive
If an organism produces two types of gametes, that organism would be described as ______
Heterozygous
Causes the production of specific molecules that will react with it and destroy certain microbes
Vaccines
It is the characteristic of all vascular plants
Conducting tissue is present
According to the heterotroph hypothesis, the first living things on Earth probably obtained food by _____
Taking in previously formed organic food from the oceans
Simple reflex vs Conditioned reflex(2)
A simple reflex action is an involuntary or automatic action which our body does in response to something.
A conditioned reflex action is an action or feeling learned in response to a stimulus; dependent on past experience, training and learning.
Instinct vs Reflex
Instict: inborn complex patterns of behaviour that exist in most members of the species
Reflex: response of an organism to a specific stimuli
The study of the principles of ecology is basic to the understanding of?
Conservation
4 characteristics of a mammal
Milk glands, warm blooded, 4 chambered heart, fur/hair
an asexual reproduction method in which a parent plant creates hundreds of reproductive units called spores, which germinate under favourable conditions and produce young organisms with numerous vegetative hyphae.
Sporulation
a process of food preservation in which packaged and unpacked foods are treated with mild heat, usually to less than 100 °C, to eliminate pathogens and extend shelf life.
Pasteurized
The chief function of guard cells is to
Permit the diffusion of gases into leaves
In dna molecules, the amount of guanine equals the amount of cytosine. This provides evidence in support of the fact that guanine and cytosine _______
Are paired in the nucleus
If a red blood cell is removed from the plasma and place in distilled water, there will be________
Some diffusion of water into the red blood cell
Most bacteria and fungi are classified as heterotroph because both of these forms of life _________
Are unable to synthesize organic compounds from inorganic substances
Which structure is observed during mitotic cell division in vascular plants but not in animals
Cell plate
Which indicates that an animal cell is undergoing mitotic cell division
Centrioles migrate in opposite direction
A a cell contained 46 chromosomes and its daughter cells contained 23 chromosomes. The daughter cells were most probably produced by the process of ________
Meiosis
