Answer:
The blank box (represents air)
Explanation:
The animal is biotic (living), the tree is also biotic (living), and the piece of wood also biotic (living.) The only abiotic factor in the photo, although we cant physically see it, is air.
Answer:
<em>3 types of front: cold front (cool air and cumulus clouds are replaced by stratus and stratocumulus clouds or clear skies) , warm front ( warm air and high clouds like cirrus), and stationary front(warm and cool air and stratus, nimbostratus, altostratus, and cirrostratus clouds. </em>
Explanation:
Cold fronts form when a cooler air mass moves into an area of warmer air in the wake of a developing extratropical cyclone. The warmer air interacts with the cooler air mass along the boundary, and usually produces precipitation. Cold fronts often follow a warm front or squall line.
Warm front Forms when a moist, warm air mass slides up and over a cold air mass. As the warm air mass rises, it condenses into a broad area of clouds. A warm front brings gentle rain or light snow, followed by warmer, milder weather.
Stationary front Forms when warm and cold air meet and neither air mass has the force to move the other. They remain stationary, or “standing still.” Where the warm and cold air meet, clouds and fog form, and it may rain or snow.
Answer:
this gene is a mitochondrial gene and therefore it is maternally inherited
Explanation:
The MT-ND5 gene is a gene of the mitochondrial genome that provides instructions for synthesizing a protein called NADH dehydrogenase 5, which is part of the complex I (the first enzyme of the respiratory chain). In most multicellular organisms, the mitochondrial DNA (mtDNA) is inherited from the mother (i.e., maternally inherited), whereas nuclear DNA (i.e., nuclear genome) is inherited equally from both parents. For example, mitochondria in human sperm are usually destroyed after fertilization. In consequence, mitochondrial mutations are transmitted by maternal inheritance, and individuals, therefore, cannot be heterozygous for mitochondrial genes.
