Answer:

Non Renewable Energy Impact on Environment

All energy sources have some impact on our environment. Fossil fuels—coal, oil, and natural gas—do substantially more harm than renewable energy sources by most measures, including air and water pollution, damage to public health, wildlife and habitat loss, water use, land use, and global warming emissions.

Density-dependent regulation

Explanation:

Most density-dependent factors, which are biological in nature (biotic), include predation, inter- and intraspecific competition, accumulation of waste, and diseases such as those caused by parasites. Usually, the denser a population is, the greater its mortality rate.

Answer:

Journal Publication

Explanation:

Once empirical data has been verified, reviewed, only then can it be published in a scientific journal. As the periodic table was developed and reconfigured, data was constantly tested, reviewed, and finally used for modifications.

Changes in the periodic table from 1800's to the present are based on all but one of these factors is Journal Publication.

Once empirical data has been verified, reviewed, only then can it be published in a scientific journal. As the periodic table was developed and reconfigured, data was constantly tested, reviewed, and finally used for modifications.

A scholarly publication is another term that may be used to describe a peer-reviewed article.

In order to maintain academic scientific excellence, the peer-review process involves having other specialists in the same field (peers) examine an author's scholarly work, study, or ideas.

Therefore, Changes in the periodic table from 1800's to the present are based on all but one of these factors is Journal Publication.

Answer:

1. For generating healthy cells to form replacement organs like brains

Stem cells can be used for curing heart disease by regenerating damaged heart tissue. The correct option is 4.

Stem cells are the raw materials of the body, the cells that give rise to all subsequent cells with specific responsibilities.

Under the right conditions, stem cells divide to establish more cells known as daughter cells in the body or in a laboratory.

Bone marrow stem cells, for example, may be able to generate bone or cardiac muscle cells.

This research has resulted in early-stage clinical trials to assess the effectiveness and safety of the product in humans.

Adult stem cells, for example, are currently being examined in people suffering from neurological or cardiovascular disease.

Thus, the correct option is 4.

Answer:

too much CO2 is toxic for humans to inhale. we rely on plants to absorb CO2 and produce O2. If they was a sudden extinction of all plants on earth, this would lead to a rise of CO2 which would reduce O2 air quality. (not good at all)

Answer:

Schwann would make statement II and Schleiden would make statement III

Explanation:

Schleiden, a German botanist and Schwann was a zoologist, both have found that the plants and animals are made up of cells, they both shared their research and observation with each other and made the conclusion that all living organisms are made up of cells.

As mentioned above Schleiden was a botanist so he must have concluded and described that all plant organs are made up of cells, similarly as zoologist he proposed that the cell must function properly in an organism.

Answer:

B- Schwann would make Statement II and Schleiden would make Statement III.

Answer:SONAR: Sound Navigation and Ranging—SONAR is a technology which uses sound wave to find and identify objects in water.

Explanation:

Answer:

In the case of the algae, each individual cell is responsible for absorbing its own water. This makes the algae nonvascular compared to the highly vascular plant species. In this connection, algae also lack several key structures that are normally present in ordinary plants like the leaves, roots and stem.

Algae are a group of aquatic organisms with autotrophic metabolism that are made up of eukaryotic cells and we can find unicellular or multicellular individuals.

Some characteristics of algae cells are:

• Cellular organization is eukaryotic (with the exception of blue-green algae), that is, they have a nucleus delimited by a double membrane, mitochondria, chloroplasts, endoplasmic reticulum, Golgi complex and lysosomes.

By definition, this type of cell is one that has a nucleus in which genetic material is stored. Compared to prokaryotic cells, eukaryotes have a large genome.

• The cell wall is made up mainly of cellulose and glycoproteins.

• In the algae cells we can find different reserve substances produced by metabolism.

The reserve substances are mainly starch, although we also find chrysolaminarin, laminarin, mannitol and paramilion in the different groups.

These substances form granules that are dispersed in the cell cytoplasm, in chloroplasts or in pyrenoids.

• They have structures of locomotion called flagella.

In different groups of algae, these organs vary in both number and shape, however, they typically present two flagella or multiples of two.

Therefore, we can conclude that algae are unicellular or multicellular photosynthetic organisms endowed with nucleus, cell wall, flagella and reserve substances.
