Which timeline shows the correct order of contributions made to the discovery of DNA?
(Options are in screenshots below!)
Answer:
The correct answer is B.
Explanation:
DNA was discovered in 1800, and then scientists studied DNA with X-Rays. After a while, scientists published a 3D model of DNA, and shortly after, scientists decoded DNA genes. So the answer is Option B.
Hopefully, this helps! :D
Ask your question below!
In the 1800s first the discovery of DNA was done, than the X-ray study of the DNA was done, after that the 3-D model of the DNA was developed, and finally human genetic code was decoded in the 1960s.
• The DNA was initially identified in the late 1860s by Friedrich Meischer, a Swiss chemist.
• After that Rosalind Franklin and Wilkins studied DNA with the help of X-ray diffraction tool.
• In the 1953s, the 3D model of the DNA molecule was discovered by Watson and Crick.
• Finally in the 1960s, Nirenberg and his colleagues at the National Institutes of Health deciphered the human genetic code.
Thus, the second timeline shows the correct order of contributions made to the discovery of DNA.

Explanation:
A species' ecological niche can be defined as the range of resources and conditions allowing the species to maintain a viable population a more simple definition is if two species have the same niche, one species will exclude the other.

What is different about normal cell division and cancer cell division?
Answer/Explanation:
Normal cell division is a very controlled process.
There are several checkpoints where the cell ensures the cell is:
receiving the correct signals to dividethat the environmental conditions are favourable for the cell to dividethat there is no damage to the DNA.However, cancerous cells proliferate uncontrollably. This is because they can bypass the checkpoints and divide without the necessary signals. This means cell division keeps occurring even when conditions are unfavourable and the DNA is damaged.

if an organism has a diploid number of 12, how many possible combinations of chromosomes could exist in its gametes with no crossing over?
a.) 8
b.)16
c.)32
d.)64
Answer: D
Explanation:
Chromosomes are the inherited unit of the organism which transfers the parental gene to the offspring.
The diploid is the paired chromosome quantity present in the cell that originates from each parent.
The correct answer is:
Option D. 64
This can be explained as:
The diploid (2n) number of chromosomes = 12Haploid (n) number of chromosome = 6The possible number of chromosome pairs is given by 2ⁿ. Where n = a haploid number of chromosomes.So, the possible combinations of chromosomes that could be found in the gametes with no crossing over will be:
= 2⁶
= 64
Therefore, 64 possible combinations of chromosomes can be present.

1. What does photosynthesis do for the plant?
2. What does cellular respiration do for the plant?
Answer:
Explanation:
1.Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel.
2.The process of cellular respiration allows plants to break down glucose into ATP. The ATP provides the energy they need to carry out various functions. Although plants use photosynthesis to produce glucose, they use cellular respiration to release energy from the glucose

What is cancer?Cancer is a diseased condition in which uncontrolled cell division takes place.
Cancer are of two main types: benign and malignant.
Benign tumours are localized to a particular organ and thus can be removed through chemotherapy or surgery.
Malignant tumours spread to body parts through blood stream and attack the healthy cells. This property of metastasis is unique to cancer cells.
Normal cells show their contact with the adjacent cells. In cancer, contact inhibition is lost and so they divide in an uncontrolled manner.
Breast cancer, leukaemia, lung cancer etc are some of the examples of cancer.
Cancer is detected through tissue biopsy. X-Rays, CT-Scan, MRI are some other techniques that detect cancer in the body.
Cancer can be treated if diagnosed early. Radiotherapy, chemotherapy and surgical intervention are the part of cancer treatment.
Therefore, cancer is considered a serious medical complication.
