Answer: I think these are the answers:
- Cancer can spread around the body.
- Cancer cells invade healthy tissue.
- Cancer cells display contact inhibition.
- Cancer comes in many forms.
- Cancer cells divide uncontrollably.
and I think "Cancer does not obey contact inhibition." is one too... I hope this helps! :D
Explanation:
Cancer cells:
• Divide uncontrollably
• Comes in many forms
• Invade healthy tissues
• Does not obey contact inhibition
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.

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.

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

The correct answer is - They did not repeat their tests multiple times
Explanation:
If a scientific process or practice which is fundamentally based on believes or idea that has no valid evidence and not proved scientifically, such type scientific process called Pseudoscience or the false science.
In this case, Both Dominic and Eva performed experiments and recorded different time periods by the same stopwatch for the same chemical reaction.
This could result in an error in the data they get and affect the conclusion or results. To avoid this experiment must be repeated to be sure of the result and eliminate errors.

Which correctly describes the role of histones in eukaryotic cell division?
a) Histones connect sister chromatids.
b) Histones protect the ends of chromosomes.
c) Histones keep the DNA compact and organized.
d) Histones copy the DNA before division begins.
Histones copy the DNA before division begins is the correct role of histones.
What is Histone?A chromosome's structural support is provided by a protein called a histone. Long DNA molecules found on each chromosome must fit into the cell nucleus.
To do it, the DNA wraps around complexes of histone proteins, giving the chromosome a more compact form. Additionally, histones are involved in the control of gene expression.
A nucleosome, which is made up of eight histone proteins, can exist. DNA can loop around a nucleosome much like a small spool. Thus, histones are crucial in maintaining the genome's order and neat wrapping inside a cell.
Therefore, Histones copy the DNA before division begins is the correct role of histones.

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.
