Weebugs get energy storage molecule from eating greenleafs. What change to the greenleaf population could decrease the number of births in the weebug population?
A) increase greenleafs
B) decrease greenleafs
A decrease in green leaves can decrease the number of Weebugs. Hence, option B is correct.
How do green leaves make energy?Green leaves are producers. They contain a pigment named chlorophyll which helps to trap sunlight which is required by the leaves to make food, and this process is called photosynthesis.
Green leaves take carbon-di-oxide, sunlight, and water, and in the presence of chlorophyll, glucose is produced and oxygen is released as a by-product. This process takes place in the chloroplast. There are four steps involved in photosynthesis that is Absorption of light, transfer of electrons, ATP production and carbon fixation,
These leaves are consumed by primary consumers such as Weebugs, and they get energy. A decrease in green leaves can decrease the number of Weebugs. Hence, option B is correct.

How do normal faults differ from reverse faults?
Answer:
In a Normal Fault, the hanging wall moves downwards relative to the foot wall. They are caused by extensional tectonics. This kind of faulting will cause the faulted section of rock to lengthen. In a Reverse Fault, the hanging wall moves upwards relative to the foot wall.

When 2 heterozygous parents (Rr) are crossed, what are the alleles of the
offspring?
a. 100% Rr
b. 50% RR, 50% Rr
c. 25% RR, 50% Rr, 25% rr
When two heterozygous parents (Rr) are crossed due to dominance effect offspring will be 25% RR, 50% Rr, 25% rr, hence c is correct option.
What is heterozygous parents?Heterozygous condition when parent having both the allele showing different trait of one character and one allele masks the trait of another allele.
When cross of heterozygous parents (Rr) x (Rr).
Gametes are R,r and R,r.
Genotype will be 25% RR, 50% Rr, and 25% rr.
Due to law of dominance, one allele R is dominant over the other allele during crossing over.
Cross of parents in punnet square is attched in image below.
Therefore, both the parents are heterozygous, so offsprings will be having genotype, 25% RR, 50% Rr, 25% rr, hence option c is correct.

A researcher attempts to use a segment of ribosomal RNA as a molecular clock to calculate the date of the last common ancestor of two species. He finds that the two species diverged from a common ancestor 150 million years ago. These particular species have abundant fossil records that strongly suggest that these species diverged 100 million years ago. Which of the following answer choices best describes a reason for the discrepancy in the date of the last common ancestor of these species?
A. Ribosomal RNA is not a reliable molecular clock and should not be used for dating.
B. The neutral mutation rate used in calculating the last common ancestor date may not have been accurate.
C. It is highly likely that the two organisms did not share a common ancestor, so the results are invalid.
D. A large portion of the ribosomal RNA is not vital to survival, so it is not likely to be well preserved.
Answer:
B
Explanation:
It is B because the mutation rate should not have been accurate if it showes that they diverged 150 million years ago. But the abundant fossil records show that it diverged 100 million years ago.

a) Archean (oldest) and
b) Proterozoic
The length of Precambrian period would be equal to the sum of length of Archaean eon and the Proterozoic eon.
The length of Proterozoic eon [tex]= 240 + 55\\[/tex]

A mother has one allele for dimples and one allele for no dimples. How many
of her gametes will carry the allele for dimples?
A. 0%
B. 25%
C. 100%
D. 50%
Answer:
50%, i believe
Explanation:
So the mother in the problem must have gotten her alleles from her mother and father. Who donated what we are not sure. All we know is that she got one allele for dimples and one allele for no dimples. These are part of the mother's somatic cell DNA. This DNA is duplicated during interphase, right before meiosis occurs as the mother begins to form her gametes, however.

Which form of nitrogen is most abundant on earth? N2 (Atmospheric Nitrogen) NH3 (Ammonia) NO2- (Nitrite) NO3- (Nitrate)
Answer:
N2 (Atmospheric Nitrogen)
Explanation:
Nitrogen is a chemical element positioned as 7 on the periodic table. Nitrogen is found as a gas in the atmosphere (N2) and constitutes the most part of the air making it the most abundant gas on Earth.
Atmospheric nitrogen (N2) is the most abundant of its form found on Earth. It can be converted to its compound form e.g. nitrates (a plant usable form) by lightning and some bacteria in the soil.
