Some birds on the Galapagos Islands build nests in trees, while others hide eggs in rock crevices. What could account for this difference in nesting behaviors?
Answers
Answer:
Food habits, predators.
Explanation:
The biggest reasons are food habits and predators, most birds who nest on the ground either can't fly or use this to be closer to their food. A ground bird (Like quail) can fly but choose to be more ground-based birds.
Most of the time it's because these birds forage for food like ground insects, seeds from the brush that grows on the ground, or fallen fruit.
Most birds that live in the trees feast on seeds, leaves, or insects found close to where they choose to nest. They may also want to escape any predators that may be towards the ground.

There is a famous psychology experiment where people sit in classroom in such a way that the person on either side of you can't hear what you say. This works best with more than 20 people.
The first person composes a sentence that has 3 facts in it. He whispers it to the second person who relays it to the third until the last person is told. The point of the experiment is to show that the last person isn't normally able to correctly repeat the 3 facts. In fact, most often what is given is quite mixed up and incorrect.
That's what's wrong with eye witness accounts. You can be certain of what you saw. You can also get it all mixed up.

In water and ice, the slightly ______ hydrogen atoms in one water molecule are drawn to the slightly _______ oxygen atom in another water molecule.
A. positive, negative
B. negative, positive
C. neutral, positive
D. neutral, negative
Answers
Answer:
option c
Explanation:
The water molecule is a polar substance that has partially charged ions. The hydrogen atom is partially positive, whereas the oxygen atom is partially negative in charge. Thus, option A is correct.
What is polarity?The polarity of the molecule is defined by the presence of the electrical charges over the elemental atom that results in the formation of the chemical bonds by the electrostatic forces.
Water is an example of a polar molecule that is linked by a covalent bond by sharing the electrons between the oxygen and the hydrogen atom of the molecule.
The hydrogen atom is said to have a partial positive charge and oxygen has a partial negative charge because of the uneven electron density. The electronegative oxygen pulls the hydrogen towards it.
Therefore, option A. hydrogen is partially positive and oxygen is partially negative.

We have all heard about earthquakes or the cyclones that attack the coastal regions. Think of as many different ways as possible in which people's health would be affected by such a disaster if it took place in our neighbourhood. (a) How many of these health -related events would occur long after the actual disaster, but would still be because of the disaster? (b) How can it affect the life of people if in case of a pandemic?
Answers
Answer:
The disease spread to the neighbourhood.
Explanation:
If the disaster such as earthquake and pandemic etc occurs in the neighbourhood so it also affected the health of the people of that region as well as the people that lives in the neighbourhood. In the case of pandemic, the disease spread to the neighboring area and affect the health of people while on the other hand, in earthquake the people of neighbourhood is also affected if the intensity of earthquake is higher.

I hope this will help you if not then sorry, have a great day :)One moth population carries three alleles at a genetic locus: X1, X2and X3. X1is dominant to X2and X3; X1produces red antennae. X2is co-dominant to X3; X2X2produces yellow antennae, X3X3produces white antennae, and X2X3produces light yellow antennae. The phenotypes in a population are as follows: 0.04 white; 0.16 light yellow; 0.16 yellow; 0.64 red.Assuming that this population is in Hardy-Weinberg equilibrium, what is the frequency of the X3allele in this population
Answers
Answer:
The correct answer is - 0.20
Explanation:
According to Hardy Weinberg equation under specific conditions the frequencies of the allele in the gene in a given population remain constant. Thus according to this frequencies of allele and genotype will remain the same through the generation unless there will be no evolutionary influence.
It helps us to predict the genotype frequencies in a large population. If there are two alleles having allelic frequencies p and q and we know equation of probability and frequencies add to 1
p2+2pq+q2=1
The X3X3 genome produces white antennae. Now Phenotypic frequency of the white antennae is 0.16 or 0.04 in the whole population. Hence the frequency of X3 should be a square root of 0.04 i.e, 0.20.
Approximately how many mutations occur naturally in DNA per 10,000 bases?
A. 2
B. 2000
C. 200
D. 20
Answers
Explanation:
Modern methods indicate that the mutation rate is roughly one to two mutation per 10,000 genes per generation.
In human cells, approximately TWO (2) MUTATIONS occur naturally in DNA per 10,000 bases (Option A is correct).
The mutation rate (u) refers to the occurrence of new mutations in a given nucleotide sequence over time.In human cells, the mutation rate is approximately 10⁻⁴ per generation.Therefore, in a DNA sequence that has 10,000 base pairs of length, this value is equal to 2 mutations per generation (u = 2 / 10,000 = 10⁻⁴).In conclusion, approximately 2 MUTATIONS occur naturally in DNA per 10,000 bases (Option A is correct).
