- Q1
Organisms whose offspring are exact copies of their parents undergo what kind of reproduction?
sexual
unisexual
asexual
bisexual
30s - Q2
Organisms are of the same species if they
can live together
can produce fertile offspring
eat the same food
grow at the same rate
30s - Q3
A chihuahua was bred with a bullmastiff. Their puppies will not exhibit
even chromosome numbers
hybrid vigor
infertility
all of these
30s - Q4
Based on the setups, it can be concluded that
B performed respiration
there is gas production even without sunlight
sunlight is a requirement for gas production
A performed photosynthesis
30s - Q5
A glowing wood splint ignites when it comes in contact with gas in A. The gas is probably
helium
carbon dioxide
nitrogen
oxygen
30s - Q6
Chalk is formed when lime water is placed near the gas in B. This gas is
nitrogen
carbon dioxide
oxygen
hydrogen
30s - Q7
Respiration
both b and c
is the reaction of food and oxygen to release energy
is the exchange of oxygen and carbon dioxide
in reptiles, birds, and mammals takes place exclusively in the lungs
30s - Q8
In his earliest experiments, Gregor Mendel worked on garden peas. The results of his studies earned him the title "Father of Modern Genetics".
Mendel first crossed purebred red-flowered plants with purebred white-flowered plants. All offspring (the F1 generation) were red. There were no white-flowered plants in the F1 generation because the gee for white is
artificial
non-existent
recessive
dominant
30s - Q9
In his earliest experiments, Gregor Mendel worked on garden peas. The results of his studies earned him the title "Father of Modern Genetics".
Next, Mendel crossed two of the red-flowered plants from the F1 generation. Six red-flowered and two white-flowered plants were produced (F2 generation). This shows that
the F1 generation plants were all purebred
the gene for red flowers is not dominant
the F1 generation contained genes for having white flowers
a mutation occurred in the breeding of two red F1 plants. producing two whites
30s - Q10
In his earliest experiments, Gregor Mendel worked on garden peas. The results of his studies earned him the title "Father of Modern Genetics".
Mendel repeated the previous cross (F1 plants x F1 plats) many more times and produced 2993 reds and 1021 whites (F2). Which of the following can be derived form all of these data?
The probability of whites in the F2 generation is inconsistent.
The phenotypic ratio in the F2 generation is 3 reds to 1 white.
The probability of whites in the F2 generation is 1/3.
The F2 plants were all halfbred.
30s - Q11
In his earliest experiments, Gregor Mendel worked on garden peas. The results of his studies earned him the title "Father of Modern Genetics".
If the allele for red is R and that for white is r, what is the genotypic ratio in the F2 generation?
1 RR : 1 Rr : 1 rr
1 RR : 1 rr
1 RR : 1 rr
1 RR : 2 Rr : 1 rr
30s - Q12
The increase in tamaraw population was greatest between
2004 and 2006
2006 and 2008
2000 and 2002
2002 and 2004
30s - Q13
The population growth rate from 2000 to 2004 is limited by
the small number of individuals
high morality rate
high reproductive rate
limiting factors of the environment
30s - Q14
Population growth from 2004 to 2006 is influenced by
adaptation of the population to the environment
the big number of reproducing individuals
all of these
heavy migration
30s - Q15
The population growth rate from 2006 to 2008 is influenced by
the small number of sexually-mature individuals
the advanced age of the population
heavy migrations
limiting factors of the environment
30s
