Environmental impacts of increased protein consumption
Explanation:
Protein is a major macronutrient that helps in body building and present more in animal sources. Hence increase in population raises the demand for more protein based foods. So, there is a huge increase in animal farming.
Animal farming directly impacts the environment as it is one of the major causes of global warming and environmental pollution.
Grazing is a common feeding method for farming animals and this reduces the greenery of vast lands which can store more carbon. Thereby these animals affect the carbon footprint.
Next, farm animals release a lot of methane in their waste products. Methane is one of the major greenhouse gases and increases global warming.
Moreover, animal waste effluents pollute the surrounding natural land and water sources with contaminants including harmful pathogens.
The answer is B.- Upright bipedal walking posture.
Answer:
d. it could be any of these three types of microbes
Explanation:
Cell wall made of peptidoglycan is a characteristic feature of bacteria that are otherwise unicellular prokaryotes.
Fungi have a chitinous cell wall and may be unicellular or multicellular. The example of unicellular fungi is yeast.
Protists are unicellular eukaryotes and have a cell wall made of cellulose.
Ribosomes are the site of protein synthesis and are present in all the organisms. Bacteria have 70S type of ribosomes while the eukaryotic fungi and protists have 80S ribosomes.
Answer:
The 2 ways abiotic factors affect biotic factors are as follows:
- An alligator submerges itself under water to stay cool in the summer.
- A naked mole rat creates burrows underground.
Explanation:
Abiotic Factors:
All non-living factors that is present or influences an ecosystem. Abiotic factors determine the dynamics of an ecosystem such as the terrain, the atmosphere as well as the inhabitant flora and fauna. Water, sunlight, oxygen, temperature, and soil are all abiotic factors.
Biotic Factors:
All living factors in an ecosystem i.e. the plants and animals.
Lets analyze all the options:
- A bird picking food out of an alligator's teeth is an interaction between 2 biotic factors, the bird and the alligator or in another case, the bird and the food.
- Water being oxygenated is an interaction between 2 abiotic factors: water and oxygen.
Ocean levels rising from glaciers melting describes the effect earths atmosphere has on earths geosphere.
Answer: Option B
<u>Explanation:</u>
Geo means earth and it talks about the ground to the bottom till the earth’s core. It also includes earth’s rock, minerals and that makes up the earth. Earth’s atmosphere causes glaciers to melt and hence the Ocean levels rise.
Though the earth’s crust seems safe there are lots of hidden things happening there is a shift happening in the earth’s plate. The ice bergs due to the rise of temperature in the atmosphere which causes the glaciers to melt hence increasing the water level.
