Answer:
lungs
Explanation:
A new study, out today, suggests that the shift to lungs and limbs doesn’t tell the full story of these creatures’ transformation. As they emerged from the sea, they gained something perhaps more precious than oxygenated air: information. In air, eyes can see much farther than they can under water. The increased visual range provided an “informational zip line” that alerted the ancient animals to bountiful food sources near the shore, according to Malcolm MacIver, a neuroscientist and engineer at Northwestern University
Answer:
All wire-haired
Explanation:
You're crossing the genotype SS with the genotype ss, so you get four boxes with the genotype Ss. This represents 4 wire-haired dogs since wire hair is dominant to the smooth. The recessive allele is not expressed; this is also known as <em>complete dominance</em>. The 'S' allele produced enough proteins for the trait to be expressed in phenotypic form.
Answer:
atoms (2), community (11) , biome (13), biosphere (14), cells (5), organism (9), ecosystem (12), molecules (3), organ (7), organelles(4), organ system (8) , population (10), subatomic particles(1), and tissues (6)
Explanation:
Levels of organization in order from the simplest to the most complex are:
- Subatomic particles-neutrons, protons and electrons that make up the atom.
- atoms- Smallest particle of a substance that may or may not exist freely.
- molecules- two atoms combine to form molecule. e.g H₂
- organelles- organelles are functioning structures of a cell. e.g. Golgi apparatus.
- cells- organelles combine to form cell. e.g. Parenchyma cells.
- tissue- cells of similar origin and function form the tissue e.g. Cardiac tissue
- organ- tissues combine together to form organs. e.g. Heart
- organ system- many organs combine together to form system. e.g Circulatory system
- organism- several organ system combine to form an organism. e.g. Human being.
- population-organism of same species form a population.
- community- different population combine to form a community.
- ecosystem- communities live in a particular area and interact with the abiotic as well as biotic factors of that area to form ecosystem. e.g. pond ecosystem
- biome-A geographical area where several ecosystem sharing same abiotic factors thrive.e.g. tiaga biome
- biosphere- Narrow zone of the earth where the atmosphere , hydrosphere and lithosphere meet to support life.
Answer:
Rise of population and over-consumption resources are key factors of climate change.
Explanation:
- The fact that climate change is real and is happening at a very fast rate. The impacts of which can be seen in terms of the increase in sea levels.
- The rise in global average mean temperatures, an increase in the melting of Greenland and Antarctic glaciers. The exposure of barren land beneath the antarctic continent.
- Therefore the scientific community s very concerned about the massive depletion of resources and the exposure of the earth's surface to solar radiation.
