What are the physical characteristics that all specimens have in common
The physical characteristics that all specimens have in common can be presence of cells, as there is no specimen given, let's take animals. A dichotomous key can be used to find the similarity.
What is a specimen?A specimen can be anything that is displayed regarding the subject. In labs the specimens can be chemicals, animals, plants, any objects, etc.
Specimens are displayed to learn about them, to see the actual version of that animal that can not be seen easily.
Thus, Because no specimen is provided, let's take animals as an example, the presence of cells is a trait that all specimens share. To find the similarity, a dichotomous key might be utilized.

Why do plants produce more carbon dioxide than oxygen during the night?
O A. Respiration produces oxygen during the day and carbon dioxide at
night.
B. Respiration can happen without sunlight, but photosynthesis
cannot.
O C. Respiration can only occur when there is no available sunlight.
O D. Photosynthesis only produces carbon dioxide during the night.
SUBMIT
Answer:
B
Explanation:
Respiration can happen without sunlight,but photosynthesis cannot.and photosynthesis doesn't take place at night,so less carbon dioxide is used up than it is produced.

Approximately how many mutations occur naturally in DNA per 10,000 bases?
A. 2
B. 2000
C. 200
D. 20
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).

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
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.

the discovery of new evidence
Explanation:
Accepted theories may be modified or overturned as new evidence and perspective emerges. Scientists are likely to accept a new or modified theory if it explains everything the old theory did and more. The process of theory change may take time and involve controversy, but eventually the scientific explanation that is more accurate will be accepted.

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?
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.

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.
