1) Genes are not visible under the microscope but chromosomes are visible under the microscope.
2) Gene mutations are small, but chromosome mutations are large.
3) Genes are composed of either DNA or RNA, but chromosomes are composed of DNA, RNA AND Histones.
4) A single gene is a locus on chromosome, but a single chromosome compromises of many genes.
Hope this helped :)
Answer:
Rivers often start from the mountain streams and contain high amounts of oxygen. Rivers and streams grow larger as these waters merge. Rivers pick up sediments from the land as they flow. Lakes support many varieties of organisms, including plants in shallow, open water and wetlands. In shallow water near shore, plankton is covered in water all or some of the time and are found along the edge of lakes and the floodplains of rivers. A deer is nibbling moss on rocks beside a river. Rivers are a major source of water for a variety of animals and plants.

Explanation:
Freshwater ecosystems are of great importance for the diversity of plants and animals; they are also of the utmost importance for people as they are used in various ways. There are differences between freshwater ecosystems and marine ecosystems; the latter cantains a large number of salts, while the freshwater ecosystem does not provide.
Freshwater ecosystems are made up of rivers, lakes, streams, among others.

Answer: It is then the space in which the life of living beings and the interaction between them and other things takes place. It is made up of living organisms, abiotic elements and artificial elements. It includes physical, chemical and biological components of the organisms and elements that form it. It is important because it is the place of habitat of humanity, it provides natural elements such as water and food, it provides fuels and raw materials that serve to manufacture artificial things and it contributes to the sustainability of life on the planet.
Explanation:
The environment is a system made up of living organisms (such as animal and plants), abiotic elements (lifeless, such as stones or water) and artificial elements (created by man, such as buildings) that are related to each other and can be modified by human action. <u>It is then the space in which the life of living beings and the interaction between them takes place</u>.
It includes physical, chemical and biological components of the organisms and elements that form it. That is, how is its composition and its function in the environment.
The importance of the environment lies in:
- It is the place of habitat of humanity, so it influences the life of human beings and future generations. It is the space where life develops at this time with all living beings and their natural components.
- It provides natural elements such as water and food since it offers all its natural resources needed by the human being.
- It provides fuels and raw materials that serve to manufacture the artificial things we use daily, to build houses, have light, transport, among many other benefits to exist.
- In the environment we find a great biological diversity of plants and animals that help maintain the ecological balance of the earth. This contributes directly to the sustainability of life on the planet. Each organism has a unique role to play.
Therefore, all societies must guarantee their care for their existence and make rational use of all their resources.
