The cells and connective tissues are arranged as follows;

Fibroblast-

1). Produces the ground substance of areolar connective tissue

2). Found in dense regular connective tissue

Osteoblast

1). Found in femur

2). Secretes hydroxyapatite

Leukocyte (WBC)

1). Reacts to bacteria.

2). Component of fluid connective tissue (i.e. blood)

Chondroblast

1). Secretes the matrix of hyaline cartilage

2). Associated with the tissue that lines movable joints.

<h3>What is Fibroblast?</h3>

Fibroblasts are non-terminally differentiated mesenchymal cells produced from embryonic mesoderm tissue.

They can be activated by a number of chemical cues that enhance proliferation and cellular differentiation, resulting in the formation of myofibroblasts with an increased rate of matrix creation.

<h3>What is Chondroblast?</h3>

Chondroblasts (also known as perichondria cells) are cells that play a crucial part in cartilage production (AKA chondrogenesis).

They are found in the perichondrium, a connective tissue layer that surrounds growing bone and protects cartilage.

A student is performing a Gram stain of a mixed culture of both E. coli and S. aureus and he forgets to decolorize with ethanol.
LuckyWell [14K]

Answer:

Correct option is C.

Explanation:

Gram staining is a technique of separation of the bacteria based on the cell wall composition. Steps involved in gram staining are:

1) Primary stain application which is known as crystal voilet, it stains all cells purple/blue.

2) Mordant stain application which is known as iodine solution, is added, and form crystal iodine complex, all cells continue to stain blue/purple.

3) Decoloration step, in this step, we can differentiate gram negative or gram positive bacteria. So, decolorizing agent such as ethanol or acetone extracts blue color from thin walled peptidoglycan layer gram negative bacteria, and gram positive bacteria remain blue/purple because it contains thick walled peptidoglycan layer.

4) Counterstain application in this step safranin red dye stain the gram negative decolorized cells red/pink, and gram positive bacteria remain same blue.

So, if a student is performing a Gram stain of a mixed culture of both E. coli and S. aureus, and he forgets to decolorize with ethanol Both the bacteria should appear blue/purple color.

*this is based on the assumption that parent two is homo_zygous dominant.

If a hetero_zygous and a homo_zygous dominant parent are crossed:

Genotypic Ratio

WW: Ww

1 : 1

Phenotypic Ratio

white : purple

[1 : 0] or [100% : 0%]

100 will have a white colour while 0 will have a purple colour.

Lynn Margulis developed the endosymbiont theory to explain the evolution of certain eukaryotic organelles, such as chloroplasts
SashulF [63]

Answer:

The answer is: letter C, The cell took in another ancient prokaryotic cell, which began living inside it.

Explanation:

"Endosymbiotic Theory" states that<em> certain eukaryotic organelles evolved when multiple cells merged together.</em> So, this created a <em>"symbiotic relationship"</em> among them. The organism that lives inside the other organism is called the "endosymbiont."

An example of this are the eukaryotic cells, which took in a <em>prokaryotic cell</em> (such as the ancient chloroplasts and mitochondrion). These ancient prokaryotes used to be free-living. They were often engulfed by another cell. However, in this theory, they are not killed; rather, the host cell helps it to thrive. <u>This caused the organelles to evolve together with the host cell.</u>

Thus, this explains the answer.
