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:

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.

Which timeline shows the correct order of contributions made to the discovery of DNA?
(Options are in screenshots below!)

Answers

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:

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.

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.

Answers

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.

What happens when magma cools during the rock cycle? Igneous rock is formed. Metamorphic rock is melted. Sediments form sedimentary rock. Metamorphic rock forms sediments.

Answers

Answer: igneous rock is formed

Explanation:

When magma cools down during the rock cycle then igneous rock is formed. Thus, the correct option is A.

What are Igneous rocks?

Igneous rock is one of the three main rock types, while the other being sedimentary and metamorphic rocks. Igneous rocks are the rocks formed through the cooling and solidification of magma or lava from volcano. The magma can be derived from partial melts of existing rocks in either a planet's mantle or the crust.

Lava from the volcano cools to form volcanic rock as well as volcanic glass. This magma can also extrude into Earth's atmosphere as part of a violent volcanic explosion. This magma then solidifies in the atmosphere to form volcanic rock called as tephra. In the atmosphere, tephra is more often called as volcanic ash.

Therefore, the correct option is A.

1)) The average depth of a lake is 10 meters. Do you think sunlight acts a limiting factor the same way it does in the ocean? Why or why not?

2)An area with a high population of crayfish in local lakes and rivers has begun experiencing acid rain, rain that has a pH of 3.0 - 4.0. Predict how this rain will impact the crayfish population.

Answers

Answer:

No.

Explanation:

No, the sunlight does not act as a limiting factor the same way it does in the ocean because the lake has lower depth as compared to ocean which is very deep i. e. more than 3000 meters where sunlight does not reach and we know that sunlight is very important for the survival of plants. Sunlight reach in the water about 1000 meters so plants can survive and do photosynthesis due to its low depth.

Acid rain will impact the crayfish population because acid rain decreases the pH of water and this lower pH causes death of the crayfish and also the food of crayfish and thus lower the population of crayfish due to unavailability of food..
