Gram-positive bacteria have more peptidoglycan in their cell walls.
Each cell in a plant is enclosed by the cell wall, a complex extracellular matrix. In 1663, Robert Hooke was able to recognize and name cells for the first time thanks to the thick cork cell walls that were visible in a crude microscope. The extracellular matrix created by animal cells is typically thinner, weaker, and—most importantly—less rigid than the walls of adjoining plant cells, which are cemented together to form the entire plant (Figure 19-68). Early plant cells lost the capacity to crawl and instead adopted a sedentary lifestyle that has survived in all living plants today by creating relatively hard walls that can be as thick as many micrometers.

What is the global variation in sea level brought about by change in the volume of water occupying the ocean basins?.
The global variation in sea level brought about by change in the volume of water occupying the ocean basins that is eustasy.
Sea level rise is therefore a climate change phenomenon that increases the volume of ocean water, primarily as a result of the melting of ice sheets and glaciers and the thermal expansion of water. Global sea levels are rising as a result of human-induced global warming, and the recent rate of rise is unprecedented in the last 2,500 years. Sea level rise is mainly caused by two factors related to global warming.
As the planet warms sea levels rise for two reasons. First, as temperatures rise land-based ice such as glaciers and ice sheets melt and the melted water flows into the sea causing sea levels to rise. Second warm water expands and takes up more space than cold water increasing the volume of ocean water. The major physical impacts of sea-level rise include coastal erosion, delta inundation, and flooding and loss of many wetlands and marshes.

List mendel’s conclusions from his experiments. How do the conclusions relate to what is known today in the field of genetics?
The main Mendel’s conclusions from his experiments include the independent segregation and dominance of characters, which are inherited from parents through factors we now know as genes.
Who was Gregor Mendel?Gregor Mendel was a Hungarian botanist who discovered the main inheritance laws by crossing pea plants that showed pure traits (i.e. they were pure lines).
Mendel discovered the principle of independent segregation which states that characters are independently inherited when they are not linked. He also observed that the characters are based on dominance features in which a character is dominant over another depending on the genetic makeup of the parent that transmits these inherited factors to offspring.
Therefore, with this data, we can see that Mendel discovered fundamental laws in genetics that are associated with the principle of genetic dominance (there are alleles that dominate others) and also the principle of independent segregation of characters.

if a dna sample analyzed is determined to be composed of 37% adenine, what percentage of thymine, cytosine, and guanine is it composed of?
If a sample of DNA is 37% adenine, it is also 63% thymine, cytosine, and guanine. This is because adenine always pairs with thymine and cytosine always pairs with guanine in DNA.
Adenine is one of four nucleobases that make up nucleic acids, which are the building blocks of DNA and RNA. The other three nucleobases are thymine, cytosine, and guanine.
In a DNA sample, if 37% of the nucleobases are adenine, then the remaining 63% must be made up of thymine, cytosine, and guanine in some proportion. We can use proportions to figure out what that proportion is.
Since we know that there are four nucleobases total, we can set up the following proportion:
37% adenine : 63% remaining nucleobases :: 1 : x
We can solve for x to find out how many nucleobases there are in total.
37% adenine : 63% remaining nucleobases :: 1 : x
37% adenine x = 63% remaining nucleobases
37% adenine x = 63% (4-1)
37% adenine x = 63% 3
37% adenine x = 189%
37% adenine x = 1.89
Hence , Adenine is 37% and the remaining is 63% which would be 21.6% Thymine, 21.6% Cytosine, and 21.6% Guanine.

your blood cells have different sizes, shapes, and functions, yet they all started out alike. what process is responsible for this? (b.6b)
The process that is responsible for the different sizes, shapes, and functions of blood cells is called blood cell differentiation. This process begins in the bone marrow, where blood cells are produced.
The blood cells that are produced in the bone marrow are called hematopoietic stem cells. These cells have the ability to divide and create new blood cells. As the hematopoietic stem cells divide, they produce different types of blood cells. The different types of blood cells include: red blood cells, white blood cells, and platelets.
Red blood cells are the most common type of blood cell. They are responsible for carrying oxygen to the body’s tissues. White blood cells are responsible for fighting infection. Platelets are responsible for clotting blood.
Once the blood cells have matured, they will be released into the bloodstream. They will then travel to the parts of the body where they are needed.

The gated sodium ion channels on the neuron's membrane suddenly open during the depolarization phase, allowing sodium ions (Na+) from outside the membrane to flood the cell.
Why is depolarization necessary?Membrane potential quickly shifts from a negative to a positive state as a result of depolarization. Initially, a stimulus triggers the depolarization process. A simple touch, a flash of light, an unwelcome object, or even an electrical impulse can serve as this stimulus. A voltage change occurs in the cell as a result of this stimulus.

The statement that describes where heterotrophs get the chemical elements they need for growth is that they obtain the carbon and nutrients they need by consuming autotrophs or other heterotrophs (option A).
What are heterotrophs?Heterotrophs are organisms which requires an external supply of energy in the form of food as it cannot synthesize its own.
Autotrophs, on the other hand, are any organism that can synthesize its food from inorganic substances, using heat or light as a source of energy.
Heterotrophs derive their energy by feeding on autotrophs or other heterotrophs. Heterotrophs that feed on autotrophic organisms are called primary consumers while heterotrophs that feed on other heterotrophs are called secondary consumers.
