Biology
1 answer:
Irina18 [472]3 years ago

White meat contains less syoglobin than red meat. Red meat contains more ( slow-twitch / fast-twitch) muscles than white meat do
Nesterboy [21]

Answer:

Slow-twitch

Explanation:

Red meat is rich in slow-twitch muscle fibers. The slow-twitch muscle fibers are rich in myoglobin and blood capillaries. They also have many large mitochondria to generate ATP by aerobic respiration.

These fibers are slow-twitch fibers as the ATPase in myosin head carries out the hydrolysis of ATP at a slower rate causing a slower contraction cycle.

Slow-twitch fibers appear red due to a large amount of myoglobin and a rich network of blood vessels. They are capable of prolonged contractions and are fatigue resistant.

Natasha2012 [34]

loblolly pine trees

Explanation:

Population density refers to the amount of organisms living in a particular area:

            Population density = \frac{number of organisms}{Area}

Area of the forest = 10acres

Population densities of:

  White-tailed deer = \frac{8 white tailed deer}{10acres}

                                 = 0.8white tailed deer/acres

   Coyotes = \frac{7 coyotes}{10acres}= 0.7coyotes/acres

   Armadillos = \frac{45 armadillos}{10acres} = 4.5armadillos/acres

   loblolly pine = \frac{231loblolly pine trees}{10acres} = 23.1loblolly pine trees/acre

The population with the highest density is that of the loblolly pine trees with 23.1 of the trees in an acre.
