Answer: A
Explanation: It most definetly not B, becuase not every form of life has DNA. A chromosome is a single chain of DNA that is coiled and super coiled to form dense thread-like pieces. The term chromosome is derived from the Greek words "chroma" or color and "some" or body and is so named because chromosomes have the ability to be stained with dyes.
This diagram represents the cell cycle. When cells leave the cell cycle, they exit during G1 phase and then enter G0 phase, a resting period. Most normal cells can leave G0 phase and reenter the cell cycle at G1 phase before entering S phase. Cancer cells are different because they cannot enter G0 phase and are likely to do which of the following?
A Fail to complete S phase
B Continuous unregulated cell division
C Mutate during G phase
D Die after completing mitosis
Write a short note on oxygen gas
Answer:
alr
Explanation:
Oxygen is a colourless, odourless, tasteless gas essential to living organisms, being taken up by animals, which convert it to carbon dioxide; plants, in turn, utilize carbon dioxide as a source of carbon and return the oxygen to the atmosphere

Edwin Chargaff was a 20th century biochemist who investigated the structure of DNA. Chargaff looked at the ratios of the four bases in the DNA. State the type of bond that joins the bases together in a DNA molecule
Answer:
Hydrogen Bond
Explanation:
The hydrogen bond joins bases together in a DNA molecules. Which is the bond between two strands on a DNA molecule. Although the hydrogen bond is weak, collectively in the DNA molecule, it is a strong bond which binds the molecule together.

In 2019, Iceland recorded 7890 births and 123 deaths per week. What was the Population Growth Rate for Iceland?
Answer:
The Population Growth Rate was 403884 in 2019
Explanation:
Lets first calculate how many total new lives per week iceland had.
Births - Deaths = New Lives
7890 - 123
=
7767
So we have 7767 lives that are new every week.
So like a 7767 growth.
But I think the growth rate is yearly.
So with 52 weeks in a year lets multiply the amount of weeks with the new lives weekly.
7767 x 52
=
403884
The Population Growth Rate was 403884 in 2019.
I hope this helps.

What are the levels of organization in the human body, starting with the cell?
Answer:
cells
v
tissues
v
organs
v
organ system
v
organism
cells make tissues that build up organs to build a organ system then organism (you,a human)
cells are the building block for life
The level of organization in the human body initiates with the cell and process in the manner which is as follows:
Cell < Tissue < Organ < Organ system < Organism. What is the level of organization?The level of organization may be defined as the process of sequence from the structures that are simplest in nature. It is usually defined by part-whole relationships, with things at higher levels being composed of things at the next lower level.
In organisms, a cell is the fundamental structural and functional unit of life. The collection of cells constitutes the formation of tissue which makes an organ that plays a specific function. Groups of organs form organ systems. While all cells, tissues, organs, and organ systems combine in order to form multicellular organisms.
Therefore, the level of organization in the human body initiates with the cell and processes in the manner which is well-described above.

rate of reproduction to sexual reproduction in plants
Answer: Asexual reproduction
For example, sexual reproduction allows for variation, but gestation usually takes a long time and it requires heavy parental input. Asexual reproduction occurs quickly, but because all of the offspring have the same genetic information, individuals are more susceptible to disease.

In the scenario above, Red hair (R) is dominant to blonde hair (r). If two parents are
heterozygous for red hair, what percentage of their offspring will have red hair and what
percentage will have blonde?
Answer:
75% of the offspring will have red hair and 25% will have blonde hair.
Explanation:
Since red is dominent but heterozygous it will be represented like Rr. Since both parents have that put it on a punnet square to get 75% red and 25% white.
