Answer:
Trout is a very common freshwater fish. The lifespan is very small.
Explanation:
The trout population is affected by the climate change and also the pollution present in the freshwater. These fish variety travel for across to lay eggs. And after laying eggs they just die. The climate change and the the fishing of this variety has negatively affected the population. There are lot of varieties of trout fish like rainbow albino etc.
The rise in temperature and flood in a river is a major factor which effects the population of this fish. in USA when the temperature rises it result in flood condition in the river which affects the lifestyle of this fish.
Answer:
The cell was first discovered in 1665 by an English scientist named Robert Hooke. While looking through a microscope, he observed tiny box-like objects in a slice of cork (bark from an oak tree) and named these boxes cells. Cells are the basic units of life, which make up all living things. This idea forms the basis of the Cell Theory. Plant cells are larger because they contain all of these structures but have some unique structures like a cell wall, vacuole and chloroplasts.
All these specialised structures are called organelles. An organelle is a tiny structure inside an animal or plant cell that has a specific function or role.
Answer:
See explanation.
Explanation:
With my current knowledge, this looks like erosion due to a combination of run off, acid rain, and sediment being carried in wind. It has happened over the course of millions of years, and will continue to happen for millions of years to come.
The atmosphere makes this acid rain precipitate and run off as well as makes the winds that erode at the rock.
Answer:
photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
The roots absorb water and minerals from the soil and anchor the plant in the ground. The stem supports the plant above ground, and carries the water and minerals to the leaves. The leaves collect energy from the Sun and make food for the plant, using an amazing process called photosynthesis.
Explanation:
Sponges are sessile animals that have specialized cells called amoebocytes and choanocytes.
Sponges (phylum Porifera) are one of the simpllest multicellular organisms (first to branch off the evolutionary tree from the common ancestor of all animals) that have bodies full of pores and channels allowing water to circulate through them. Sponges’ s structure consists of two thin layers of cells and mesohyl layer between them. They don’ t have real tissues or organ systems such as nervous, digestive or circulatory systems. Constant water flow through their openings and pores obtain food and oxygen and remove wastes.
