"If a cell is compared to a home, then name the cell organelles which would represent the given parts of a home: • Door • Parents • Kitchen • Electric Mains • Store Room • Dustbin"

Answers

Door: Cell membrane

Parents: Nucleus

Kitchen: Endoplasmic Reticulum (smooth & Rough)

Electric Mains: Mitochondria

Store Room: Vacuoles and vesicles

Dustbin: Lysosome
________________________________

In this cell-to-home analogy:

• The Cell Membrane is like a door because it controls what enters and exits the cell, much like a door regulates who enters and leaves a home.
• The Nucleus represents parents because it holds genetic information, like parents pass on their genetic information to their children.
• The Endoplasmic Reticulum (both smooth and rough ER) is like a kitchen where various tasks, such as making and processing materials, take place, similar to food preparation in a kitchen.
• Mitochondria serve as the electric mains, generating energy for the cell, just like the electric mains provide power to a home.
• Vacuoles and Vesicles act as storage rooms in a cell, akin to a home’s store room used for holding various items.
• Lysosomes function as a dustbin, breaking down waste and cellular debris, like a dustbin collects and disposes of trash in a home.

A new fossil is found, and scientists are debating whether it can be considered a part of the human genus Homo. What piece of evidence would best indicate that the fossil is human?large jaw bone for muscle attachment

pelvic blades rotated inward

very long arms

thick rib cage

Answers

The answer is large jaw bone for muscle attachment.

Pelvic blades are rotated inward anyway, so it is not the right answer. Very long arms are characteristic of many other animals, as well as a thick rib cage is. This leaves a large jaw bone for muscle attachment as the right answer. This trait is an adaptation to eating large quantities of food.

The correct answer is:

large jaw bone for muscle attachment.

Pelvic blades are rotated inward anyway, so it is not the right answer. Very long arms are characteristic of many other animals, as well as a thick rib cage is. This leaves a large jaw bone for muscle attachment as the right answer. This trait is an adaptation to eating large quantities of food.

Explanation:

By analyzing the fossil record we can tell how long life has remained on Earth, and how different plants and animals are compared to each other. The mandible, lower jaw or jawbone is the biggest, greatest and lowest bone in the human face. It affects the lower jaw and holds the lower teeth in place. The mandible sits below the maxilla. It is the only movable bone of the skull.

A scientist has correctly gone through all the possible steps in a dichotomous key, but has not identified an insect. Which most likely describes why he did not identify the insect?

Answers

The answer to this question is letter C. The organism evolved during identification.
A scientist has correctly gone through all the possible steps in a dichotomous key, but has not identified an insect. He was not able to identify the insect because the organism evolved during identification.

Choices to this question are:
A) The scientist must have made a mistake.
B) The insect might be an unknown variation or a new species.
C) The organism evolved during identification.
D) The dichotomous key had to many questions.

Answer;

The insect might be an unknown variation or a new species.

Explanation;

A dichotomous key is a biological tool that is used by scientists to identify unknown organisms. It is used to identify organisms in an ecosystem such as trees, mammals, fish, etc.
Dichotomous key consist of a series of steps or statements about a specific characteristics of organisms that leads to the correct name of a given organism.
If the scientist went through all the possible steps correctly in a dichotomous key and was unable to identify the insect, it means the insect might have been unknown variation or a new species.

Why is the model used to describe the plasma membrane called the fluid mosaic model?

Answers

Answer:

Because proteins and lipid tails are free to move and are not bonded by strong interactions with each other.

Explanation:

The plasma membranes have two layers of phospholipids in which proteins are present. The hydrophobic fatty acid tails of phospholipid layers make the inner core of the membranes. However, the tails are not bonded to each other and make a fluid-like base in which proteins are present. Also, the membrane proteins are not bonded to the phospholipids and are free to change their position within the phospholipid leaflets. This is why the model is described as a fluid mosaic model.
