A cell. it is the smallest unit of life that can reproduce indepentantly
Answer:
Explanation:
Transcription and translation The information stored in a gene's DNA is transferred to a similar molecule called RNA (ribonucleic acid) in the cell nucleus during the transcription process. During protein synthesis, translation is the process of converting the sequence of a messenger RNA (mRNA) molecule to a sequence of amino acids. The genetic code describes the relationship between the base pair sequence in a gene and the amino acid sequence that it encodes.
During respiration, the diaphragm moves upwards and returns to dome shape from the flattened shape before during expiration.
This movement of diaphragm can decrease the lung volume, increase the pressure inside and thus force the air out. This process is expiration.
However, if we breathe in again, which makes that inhalation, the diaphragm moves downwards into a flat shape so that it can increase the lung volume and thus we can breathe in as much air we can. This process is completely opposite from expiration.
Explanation:
An environment's biology includes both abiotic factors like atmosphere, water, soil, sunlight and temperature; and biotic factors which are living components of the ecosystem. These factors lead to a gradual change of an ecosystem over time; however, humans drastically impact the environment through over-exploitation and pollution- we disrupt normal abiotic and biotic interactions. Furthermore, human impact can lead to population die-offs and extinction events, along with food and water scarcity.
Human impact on the environment can manifest as:
- overpopulation- natural resources are over used, and habitats cannot support human communities;
- urban communities also expand by cutting down trees in deforestation- this leads to erosion and flooding;
- burning fossil fuels- this reduces air quality and adds carbon dioxide to the environment leading to global warming;
- pollution- adding contaminants to the atmosphere, waterways, soil etc.
Leaves change in the fall via a natural process; in green leaves the photosynthetic pigment, Chlorphyll a is produced in significantly lower amounts. Other pigment molecules that absorb and reflect different wavelengths exist in larger concentrations- their effect is more apparent, leading to visibly orange-red leaves.
