How do structures in living things compare to structures in non living things

1 answer:

7 0

First of all there is no such thing as non living organisms, Ok because living things are only termed as organisms.

Now some of the characterisitic differences between the living and non living are :

1. Cellular structure: all living organisms generally have a cellular structure i.e., they are made up of one or more cells.
The protoplasm is the physical basis of life.

There is no such fundamental and structural unit called cell in non living things.

2. metabolism : The various life processes taking place within the body of an organism is collectively termed metabolism. The metabolic processes can occur only in living organisms and not in non living things.

3. growth, repair and death : Growth consists of the living organism absorbing materials entirely different from those that make up its body and convert thm into body building substances. Growth in non living substances such as crystal is at the cost of material similar to that of which it consists. Same substance is added without conversion.
The growth is permanent, irreversible process in living organisms but can be reversed in non living things.
Growth is different in different parts of the body of an organism. Growth is uniform throughout in the non living things.

Respiration, nutrition,excretion, movement,irritability, reproduction, life span, death, evolvability are other properties of a living organism.

Romashka [77]

Answer:

Is composed of trabeculae that are oriented along lines of stress. (Ans. D)

Explanation:

Spongy bones are also known as trabecular and cancellous bones. It is covered by compact bones and present in the long bones. They are known as spongy because they are highly vascular and porous tissues.

Osteoblast thin area creating the turbeculae space between the tissues. Spongy bones are also known for home of hematopoietic stem cells and bone marrow, which are helping to differentiate white blood cells, red blood cells, and platelets.

Some difference between spongy bone and compact bone are:

1) Spongy bones are light weight and compact bones are heavy.

2) Spongy bones are composed of trabeculae and compact bones are composed of osteons.

3) Spongy bones are known as cancellous and compact bones are known as cortical bones.

4vir4ik [10]

Answer:

This question is asking to fill in the blank spaces with the correct terms. The correct terms to the four blank spaces are:

1) GEL

2) DYE

3) DNA MARKER

4) LID

Explanation:

This question is describing the Gel electrophoresis technique which is used to separate DNA fragments using electric current. The DNA fragments of different sizes migrate through a GEL which serves as the matrix made from Agarose.

In order to physically see the samples that we put in the gel, we first have to add DYE to each sample of DNA. After loading the samples to be separated, a substance made up of DNA fragments of known sizes referred to as DNA MARKER, which acts as the standard curve in a tube is used.

Before running the gel, it's important to make sure that there is LID covering the gel in the gel rig. This will make sure that the electrical current runs through the gel and the gel stays cool.

What are the processes that change one type of rock into another type in the rock cycle?

zloy xaker [14]

Answer:

Crystallization (cooling or solidification)
Erosion and sedimentation (lithification, burial and deposition)
Metamorphism (Melting due to heat and pressure)

Explanation:

In rock cycle, there are three important processes that changes one type of rocks into another type. Those processes are:

Crystallization: It is a process that takes place under the earth surface where magma cools down and is hardened to form igneous rocks. This process is also called freezing of rocks.
Erosion and sedimentation: The rocks on the surface of earth are broken into smaller fragments called sediments that are formed by weathering of rocks. These sediments are then carried either by wind or water to different places and settles at some place to form another type of rock named sedimentary rocks.
Metamorphism: Metamorphism takes place under the earth surface where extreme heat changes the mineral texture of the rock but does not melt it. such rocks are named as metamorphic rocks.
