Answer:

The levels, from smallest to largest, are: molecule, cell, tissue, organ, organ system, organism, population, community, ecosystem, biosphere.

Explanation:

Molecule

Molecules are made of atoms, the smallest unit of chemical elements. They can be found in all matter, living and non-living. Molecules make up the most basic structures of living beings. Two biological disciplines that focus on this level are biochemistry and molecular biology.

Cell

A cell is the basic unit of life. There are two kinds of cells: plant cells, which have a rigid cell wall made of cellulose molecules, and animal cells, which have flexible cell membranes. Cell biologists consider questions such as metabolism and other questions about structure and function within and between cells.

Tissue

Tissue is made of cells that work together to perform a certain task. Muscle tissue, connective tissue, and neural tissue are some types of tissue. Histologists are an example of biologists who work at this level.

Organ

An organ is a system of tissues that work together on a larger scale to do certain jobs within an animal's body. Examples of organs are the brain, heart and lungs. Anatomy is an example of a biology specialty concerned with this level.

Organ System

An organ system is a group of organs that work together to perform specific bodily functions. The respiratory system, for example, uses the lungs, airways and respiratory muscles to inhale oxygen and release carbon dioxide in animals. Physiologists study the function of parts of the body as they work together. Though physiologists can work at any level of biological organization, they often answer questions related to organ systems.

Organism

An organism is a recognizable, self-contained individual. Organisms can be unicellular organisms such as bacteria or amoebae, or multi-cellular organisms comprised of organs and organ systems. A human being is an example of a multi-cellular organism.

Population

A population is a group of multiple organisms of the same species within a specific area. For example, a pride of lions in Kenya, Africa, is a population.

Community

A community consists of all the different species within a certain area. The population of lions in Kenya, plus the populations of gazelles, giraffes, elephants, dung beetles, and all other species in that area, add up to a community.

Ecosystem

An ecosystem is made up of all the communities in a certain area, as well as all the non-living, physical components of the environment. Rocks, water and dirt are a part of an ecosystem. Ecologists may study populations, communities, or whole ecosystems.

Biosphere

The biosphere is all of the ecosystems on Earth added together. Every animal, plant, bacteria, rock, and molecule is a part of the Earth's biosphere. Non-biologists, such as meteorologists and geologists, may join biologists to answer questions at this level of biology organization.

Answer: So there are 5 levels,

to describe it you'd have to say :

At first level there are CELLS that makes up the TISSUES in hich the tissues makes up the plant's ORGANS and these organs combine to make the ORGAN SYSTEM.

goldenfox [79]

Answer:

Yes, Religion has a great influence on society.

Explanation:

Religion has a great influence on society, art, culture and politics because religious touch all these aspects of life. Religion is a way of life that is followed by the people in every aspects of life which directly affect the society and other related fields. A religious society follow their religion in their politics, culture and also in their architecture. So we can conclude that religious has a great influence on society, art, politics and culture of people.

Why is breaking and rearranging bonds in the process of photosynthesis and cellular respiration important? WILL GIVE BRAINLIEST

____ [38]

Answer:

Photosynthesis

All organisms in the plant kingdom are autotrophs/producers and therefore carry out photosynthesis. Photosynthesis occurs in the chloroplast (figure 1) of plant cells which are concentrated predominantly in the leaves. The chloroplasts contain the green pigment chlorophyll, giving leaves their green color, and is responsible for capturing light energy to power photosynthesis.

Picture

Figure 1

All living things need a few basic things to survive, we learned these things as the four basic needs of living things. Plants are no exception to this and require space, gases, food, and water like all other living organisms.

The two basic needs, water and gas are especially important for a plant to carry out photosynthesis. The water and gas makeup two of the three reactants of photosynthesis. The needed water (H2O) is absorbed from underground into the roots of the plant and is then transported to each cell by the vascular tissue xylem.

Picture

Figure 2 https://upload.wikimedia.org/wikipedia/commons/d/db/ Photosynthesis.gif

Plants cannot carry out photosynthesis without carbon dioxide (CO2), the gas animals exhale. Plants take in CO2 and release O2 (the opposite of animals) by the process of transpiration (respiration in animals).

Although plants do not have lungs or lung-like structures, they do have small pores on the underside of their leaves that regulate transpiration. These pores are called stoma or stomata and allow CO2 and O2 to enter and exit the plant leaves. Each stoma is surrounded by two guard cells that open and close the stoma. Stomata remain open when the plant is in need of CO2, during photosynthesis, and closed during times of photosynthetic inactivity. You will be conducting a lab during which you will test when stomata tend to be open vs when they tend to be closed.

In addition to CO2 and H2O, plants must also have sunlight or light energy. As mentioned above, the light energy absorbed by the chlorophyll powers the process of photosynthesis. Sunlight is responsible for breaking the molecular bonds of the CO2 and H2O and then rearranging the atoms into the products of photosynthesis, glucose (C6H12O6) and oxygen (O2). Through photosynthesis, light energy is converted into stored energy, the glucose (food).

To summarize: Energy from the sun is converted into stored chemical energy or food called glucose in the plant cell by the process of photosynthesis. The green pigment- chlorophyll- is located in the chloroplast and captures the sunlight. The energy from the sun is then used to change the carbon dioxide and water into the sugar glucose and oxygen. Glucose is a sugar that is stored energy for later use.

What is the most important factor that determines the rate of diffusion in biological systems?

miv72 [106K]

The factors that determines the rate of diffusion in the biological system include: temperature, size of the particles, diffusion distance and concentration gradients. Of all these factors, the most important one is the TEMPERATURE.
The relationship between temperature and the rate of diffusion is a direct one, that is, the higher the temperature the higher the rate of diffusion and vice versa. At high temperature the molecules in the particles move faster because they have higher amount of energy.
