Answer:
1 g/cm³
Explanation:
To find density we need to know the mass and the volume. We already know that the mass is 8 g. Now we need to know the volume using the dimensions above, so all we need to do is
2cmX4cmX1cm to give us 8cm³
Now that we know both the mass and the volume all we have to is to divide the mass(8g) by the volume(8cm³) to give us 1g/cm³(which btw is almost always the constant density of water)
Creating a formula by _____ to the specific cells that are to be part of the formula is more accurate than typing the cell references.
Creating a formula by pointing to the specific cells that are to be part of the formula is more accurate than typing the cell references.
This is further explained below.
What are cell references?Generally, When working with Excel, you may refer to the value of a separate cell or cell range on the same worksheet or on a different worksheet inside the same spreadsheet by using something called a cell reference.
In a formula, a cell reference may stand in for a variable if the need arises.
In conclusion, Rather than manually putting in the cell references, it is more accurate to create a formula by pointing to the individual cells that need to be included in the formula.

The majority of the plasma membrane can be described as a bilayer of with associated proteins.
The majority of the plasma membrane can be described as a bilayer of Phospholipids with associated proteins.
What is the plasma membrane?It is a double layer of phospholipids and proteins, which perform functions of connection, transport and catalysis, which covers and delimits the cells, serving as a border between the inside and the outside of it.
In this sense, one of the peculiarities of phospholipids is that they are amphipathic, their molecules have a part that is soluble in water (that is, hydrophilic) and another that is not (hydrophobic), these lipids are primarily cholesterol, phosphoglycerides and sphingolipids.
Therefore, we can conclude that according to the research, the correct option is phospholipids. The majority of the plasma membrane can be described as a bilayer of phospholipids with associated proteins.

Proteins is a property of permeability is a property of solutes. It can be expressed in a variety of ways. A solution's ligative qualities are determined only by the total quantity of dissolved particles in solution, not by their chemical identity. Vapor pressure, boiling point, freezing point, and osmotic pressure are examples of ligative qualities.
We will look at four important colligative properties: vapor pressure depression, boiling point elevation, freezing point depression, and osmotic pressure. These are known as colligative qualities.

An advantageous mutation is more likely to get fixed in a population through genetic drift than is a deleterious mutation. true/ false
False: an advantageous mutation can get fixed in a population through genetic drift than a deleterious mutation.
A mutation is a change in the sequence of DNA of an organism. It can be a result of errors in the replication of DNA during cell division, exposure to mutagens, or any infection.
Genetic drift: The fluctuations in the number of variations in genes of a population are called genetic drift. It takes place when the occurrence of variant forms of a gene, called alleles. Which increases or decreases by chance over time.
Deleterious mutation: An alteration of genetic material that increases an individual's susceptibility to a certain disease or disorder. In this mutation, the protein product of a gene is not produced, and if it is produced it does not function, or if produced it interferes with normal function.

What is the most appropriate unit of measurement for macromolecular complexes including ribosomes and microfilaments?
Nanometer is the most appropriate unit of measurement for macromolecular complexes including ribosomes and microfilaments.
One billionth of a meter, or [tex]10^{-9}[/tex] meters, is the size of a nanometer, which is a measure of spatial measurement. It is frequently employed in nanotechnology, which involves creating incredibly small machines. Because it is [tex]\frac{1}{10}[/tex] of a micron (micrometer), the nanometer was previously known as the millimicrometre, or more popularly, the millimicron. It was frequently represented by the symbol m, or (less frequently and confusingly, because it conceptually should represent to a millionth of a micron). The thickness of a typical human hair is 60,000 nanometers. Light wavelengths and the separations across atoms in molecules can both be measured using nanometers.

One of the primary functions of sebum is: ________
a. protection against infection
b. hair growth
c. tissue repair
d. scar development
e. excoriation
One of the primary functions of sebum is : protection against infection.
Sebum is an oily substance that the sebaceous glands produce. It combines with lipid molecules, which are fat molecules, to create a protective layer on the skin's surface. These lipids aid in hydrating the skin and shielding it from pathogens like bacteria and fungi that could be harmful.
Sebum helps in providing infection protection in the following ways:
90% of the lipids, or fat molecules, on the skin's surface are contributed by sebum. These lipids keep the skin moist and shield it from UV rays and other irritants.Fat-soluble antioxidants, like vitamin E, are also transported to the surface of the skin by the sebum. By taking this action, skin oxidative damage might be avoided.Atopic dermatitis and staph infections are both brought on by the Staphylococcus aureus bacteria, which is also fought off by sapienic acid and other fatty acids in sebum.Squalene and many of the fatty acids found in sebum, as well as other sebum constituents, have anti-inflammatory properties.Find more on Sebum at : brainly.com/question/10723558

The type of leukocyte that will migrate in the blood and take up residence in the tissues as a macrophage is a : monocyte .
Monocytes can be thought of as a subtype of leukocyte, or white blood cell. They can differentiate into macrophages and typical dendritic cells, making them the largest type of leukocyte in blood. Involved in tissue repair and innately adaptive immune responses in vertebrates.
Leukocytes of the monocyte type enter tissues as macrophages after leaving the bloodstream. And, based on their phenotypic receptors, the monocyte subclasses in human blood are at least three.
Function: The precursors of tissue macrophages that are actively phagocytic are termed as monocytes, which circulate in the blood. For one to three days, monocytes circulate in the blood before migrating into body tissues, where they further develop into macrophages.
