Answer:
red blood cells, which contain no DNA in their mature state, and some immune system cells that rearrange their DNA while producing antibodies
Cell is the basic unit of life and they contain the needed information known as the DNA (genetic material) to carry out the basic life functions and processes.
All cells in the body essentially have the same genome except some red blood cells and some immune cells.
Red blood cells do not contain as DNA as they lack a nucleus so they are an exception to the rule. While some immune cells needs to reassemble their genome in order to aid in the production of antibodies.
Actually, gene expression comes in with this because cells become different as a result of the fact that a cell can decide which gene is to be expressed or not in accordance to its function it is supposed to perform.

What effect does viscosity have on blood flow?
A.) Low blood viscosity leads to slower blood flow.
B.) High blood viscosity leads to slower blood flow.
C.) Low blood viscosity increases resistance and leads to fast blood flow.
D.) High blood viscosity decreases resistance and leads to fast blood flow.
Answer:
B
Explanation:
High blood viscosity leads to slower blood flow. Therefore, option B is correct.
What is viscosity?Viscosity is a measure of a fluid's resistance to flow. It describes the internal friction between different layers of fluid as they move relative to one another. In general, fluids with high viscosity flow more slowly than fluids with low viscosity.
Viscosity can affect blood flow by altering the resistance to blood flow in blood vessels. Blood viscosity is influenced by the thickness and stickiness of blood, which is determined by the concentration of various proteins and cells in the blood.
When blood viscosity is high, the blood is thicker and flows more slowly, which can increase the resistance to blood flow in blood vessels. Therefore, option B is correct.

through which material would you expect sound waves to move fastest
Answer:
Solids
Explanation:
Sound travels fastest through solids. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it. In fact, sound waves travel over 17 times faster through steel than through air.
The trapezius is a(n) _____ to the pectoralis major.
Answer:
complement
Explanation:
The trapezius is a complement to the pectoralis major.
What is Trapezius?The trapezius may be characterized as one of the widest and most superficial muscles that are located in the upper back and trunk region. It is triangular in structure, wide, and thin that encircles the upper back of the shoulders and neck.
While the pectoralis major is the most superior and largest muscle that is located within the region of the anterior chest wall. This muscle is thick, fan-shaped in appearance positioned beneath the breast tissue, and constructs the anterior wall of the axilla.
Both of these muscle types complement each other in every aspect such as location, structure, appearance, etc.
Therefore, The trapezius is a complement to the pectoralis major.

During interphase, how does a cell prepare for division? Describe cell division, including the processes of mitosis and cytokinesis. Be sure to describe the mitotic steps.
Answer: Interphase is the phase in the cell cycle during which cells that will undergo mitosis prepare for division. In interphase, DNA of the cell copies. After that cell undergoes mitosis, which is the phase of the cell cycle during which cell divides on two identical. Mitosis consists of four phases:
1. Prophase: Chromatin in the nucleus condenses and chromosomes pair up
2. Metaphase: Chromosomes line up at the centre of the cell.
3. Anaphase: The sister chromatids separate from each other to the opposite sides of the cells.
4. Telophase and Cytokinesis: Membrane forms around each set of chromosomes on two opposite sides of the cells and cell divides into two identical daughter cells.

Axons insulated by a(n) _____ are able to conduct impulses faster that those not so insulated.
Answer:
Much like the insulation around the wires in electrical systems, glial cells form a membraneous sheath surrounding axons called myelin, thereby insulating the axon. This myelination, as it is called, can greatly increase the speed of signals transmitted between neurons (known as action potentials).

What is the function of the cell membrane? The cell membrane controls what goes into the cell (food) and what leaves the cell (waste). The cell membrane protects the cell from damage. The cell membrane controls the amount of water that goes into the cell and stores it there if it doesn't rain. The cell membrane allows air to enter, but won't allow water to enter into the cell.
Answer:
Cell membranes serve as barriers and gatekeepers. They are semi-permeable, which means that some molecules can diffuse across the lipid bilayer but others cannot. Small hydrophobic molecules and gases like oxygen and carbon dioxide cross membranes rapidly
Explanation:
How does cytokinesis in plant cells differ from cytokinesis in animal cells?
animal cells form a cell plate
plant cells form a cell plate
plant cells go through the process in reverse
plant cells go through two rounds of cytokinesis while animal cells just do once
Answer:
During cytokinesis in animal cells, a ring of actin filaments forms at the metaphase plate. The ring contracts, forming a cleavage furrow, which divides the cell in two. In plant cells, Golgi vesicles coalesce at the former metaphase plate, forming a phragmoplast.

What does it mean to be 'alive'? At a basic level, viruses are proteins and genetic material that survive and replicate within their environment, inside another life form. In the absence of their host, viruses are unable to replicate and many are unable to survive for long in the extracellular environment.
Answer:
B
Explanation:
The nuclei is basically like the heart of a cell.
What is the important of ecological factors to organisms
Explanation:
The ecological factors that affect the growth of plants and determine the nature of plant communities are divided into three types.
The three types of ecological factors are: (1) Climatic factors which include rainfall, atmospheric humidity, wind, atmospheric gases, temperature and light (2) Physiographic factors which include altitude, effect of steepness and sunlight on vegetation and direction of slopes (3) Biotic factors which include interrelationship between different plants of a particular area, interrelationship between plants and animals occupying the same area and interrelationship between soil microorganisms and plants.
I. Climatic Factors:
The important climatic factors of a region are rainfall, atmospheric humidity, wind, temperature, and light. Of these climatic factors each one individually contributes to the general and overall effect of climate by influencing the life processes of plants which constitute the vegetation.
