Answer:
<h2><u>
directional selection</u></h2>
Explanation:
This type of natural selection is referred to as . In this type of natural selection, either one phenotype is preferred or the other; therefore, there is no equilibrium between the populations of the phenotypes that are present.
Examples of organisms that have undergone directional selection are black bears during the ice ages, African chichlid and sockey salmon.
Answer:
The quadrant with more probabilities of overgrazing would be the one in which the drinkers and the rest zone is.
Explanation:
When a farmer has cattle for beef, most of them divide the land in quarters and limit each of them, this is to keep the cattle in only one quarter to make sure they eat all the forages in there and then they pass to the next quarter, this gives the other quarters (the forage) time to grow properly.
If the farmer uses all the four quarters, the natural behavior of the cattle would make the quarter that has the drinkers and the rest zone to be more likely to have an overgrazing.
This is because cows look for their aliments near them and near their comfort zone, they only move when the forage of that area is over.
Answer:
The correct answer is B
Explanation:
Mitochondria are membrane-bound cellular organelles that are found in eukaryotic plant and animal cells that produce high energy compounds (called ATP) that are responsible for cellular activities.
NOTE: ATP (adenosine triphosphate) is described as the unit for energy in biology, hence the answer is B
The correct answer is marsupials.
<span>Marsupials are any members of the mammalian class Marsupialia and are endemic to Australasia and the Americas. The main characteristic common to these species is that most of the young are carried in a pouch because they give birth to relatively undeveloped young. Examples of marsupials include kangaroos, wallabies, koalas, possums, opossums, wombats, and Tasmanian devils. </span>
Solution:
The series of processes by which carbon compounds are interconverted in the environment, involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels. And the oxygen cycle is a biogeochemical cycle that describes the movement of oxygen within the earth's three main reservoirs which are the atmosphere (air), the hydrosphere (water), and the lithosphere (land).
Both mix in one cycle because of these:
The C2 oxidative photosynthetic carbon cycle plus the C3 reductive photosynthetic carbon cycle coexist. Both are initiated by Rubisco, use about equal amounts of energy, must regenerate RuBP, and result in exchanges of CO2 and O2 to establish rates of net photosynthesis, CO2 and O2 compensation points, and the ratio of CO2 and O2 in the atmosphere. These concepts evolved from research on O2 inhibition, glycolate metabolism, leaf peroxisomes, photorespiration, 18O2/ 16O2 exchange,CO2 concentrating processes, and a requirement for the oxygenase activity of Rubisco
