In mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells, same number chromosomes.
What is chromosome ?
A chromosome is defined as a thread-like structure present in the nucleus of cells such as both prokaryotic and eukaryotic cell and it is made of a molecule of DNA (Deoxyribonucleic acid) and histone proteins.
It is composed of three components, DNA, proteins and RNA, amount of the DNA content ranges from 30 to 40 %, the amount of proteins from 50 to 65%, and small amount of RNA from 1 to 10%.
Two types of protein present in DNA such as histone and non-histones proteins, histone constitute large amount (90% of total protein), whereas non-histone is present in small amount (around 10% of total protein).
The histone protein is basic, whereas, the DNA is acidic, so it can be neutralized; DNA in chromosome is present in two forms such as Euchromatin and Heterochromatin.

How do cell differentiation and cell division work together?
Answer:
Cell differentiation and cell division both work together by starting out with a somatic cell(basic cell) and cell differentiation gives it the specific instructions in the DNA to enable it to perform its function, then cell division comes in also known as mitosis, and it makes the cell with the whole package included with its function

Why is having a cell that is too large detrimental?
Explanation:
If a cell became too large, an "information crisis" would occur. The cell has more trouble moving enough nutrients and wastes across the cell membrane. The rate at which food, oxygen, and water enter the cell, as well as wast products leave the cell, depends on the surface area of the cell and the cell's volume.

What actions are required to address the health consequences of ecosystem change?
Answer:
mitigation and adaptation strategies
Explanation:
There are two manners to avoid/prevent health problems caused by ecosystem disruption: 1-mitigation techniques: consist of preventing or limiting environmental damages, and thereby reducing or reversing the change process; and 2- adaptation techniques: with the goal of protecting individuals/populations from the consequences of environmental change, increasing the resilience of societies and ecosystems. In this regard, it is important to highlight that current strategies are aimed at achieving actions to both reduce human vulnerability and protect the ecosystems.

Answer:
Heterotroph. Autotrophs are organisms that can produce their own food from the substances available in their surroundings using light (photosynthesis) or chemical energy (chemosynthesis). Heterotrophs cannot synthesize their own food and rely on other organisms — both plants and animals — for nutrition.

Explanation:
Answer:
Hi there! The answer is, The function of red blood cells is to transport oxygen (O2).
Explanation:
Blood cells carry a protein called hemoglobin at the top of their disc surface. This protein allows oxygen to bind to it and thus creates an oxygen rich surface that is then carried throughout the body.

What do plants produce when they make their own food?
Answer:
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. These primary producers form the base of an ecosystem and fuel the next trophic levels.
Explanation:
Answer:
Their roots take up water and minerals from the ground and their leaves absorb a gas called carbon dioxide (CO2) from the air. They convert these ingredients into food by using energy from sunlight. This process is called photosynthesis, which means ‘making out of light’. The foods are called glucose and starch

Answer:
Animals can move, but plants cannot
Explanation:
Locomotion in humans and bipeds is accomplished through walking on legs. In other animals, it can be accomplished through walking on four limbs, flying, or swimming. In cells, cilia and flagella are used to move about. However, since plants are not capable of moving themselves, there is no locomotion of plant species.
