The loulu tree in Hawaii reproduces by a see encased in fruit.
Non-native species, such as pigs and rats, eat the fruit as a regular
part of their diet, drastically reducing the regeneration rate of the
loulu. What most likely would be the outcome for loulu trees in the
next century without intervention? - ANSWER the would become
extinct
,Which of these would lead to a lower rate of photosynthesis in a
plant? - ANSWER a decrease in the amount of carbon dioxide in
the air
What is the result of the fertilization of an egg? - ANSWER it
restores the diploid number of chromosomes
Which of these best describes the initial change caused by a DNA
mutation? - ANSWER a change in the sequence of base pairs
A new species of snake was introduced to a tropical region. Scientists
then notices a steady decline in the presence of field mice and an
increase in the number of snakes. Which of these is the most likely
explanation about why the population size of each animal changed? -
ANSWER The mice became prey to the introduced
snakes, allowing the snake population to increase but decreasing the
mice population
Which statement best describes an advantage of asexual
reproduction for a population of organisms? - ANSWER the
population can increase in number more rapidly
The following cell structures are located within cells that make
proteins. Which description best explains the relationship among
these cell structures in making a protein.
Nucleus, Ribosome, Endoplasmic Reticulum (ER) - ANSWER DNA
in nucleus codes for protein - protein assembled in ribosomes and
, moves to ER - protein folds into its active shape
