Their close proximity to humans in the burial process is evidence that the animals were domesticated. This, along with artifacts and art depicting dogs in positive ways, shows that humans and dogs have had close relationships for thousands of years.</span>

Anyone know about cellular respiration? Please help me label, 60 points!
matrenka [14]

Answer:

Mitochondria- glycolysis

ATP synthase- converts ADP to ATP

Inner membrane- electron transport chain

Matrix- krebs cycle

Explanation:

The mitochondria forms the fundamental site for glycolysis. The glucose is broken down enzymatically to produce carbon dioxide, water and ATP. The krebs cycle is the first stage of aerobic respiration. It takes place in the mitochondrial matrix. ATP synthase is an enzyme that generates ATP during the process of cellular respiration. ATP synthase forms ATP from ADP and an inorganic phosphate (Pi) through oxidative phosphorylation. The mitochondrial inner membrane is the site of the electron transport chain, an important step in aerobic respiration.  Energy obtained through the transfer of electrons down the ETC is used to pump protons from the matrix into the intermembrane space, creating an electrochemical proton gradient generating ATP.

You observe that your friend has dimples. dimples result from the presence of the dominant gene d; absence of dimples is a homoz
anzhelika [568]

Answer:

DD or Dd

Explanation:

Dimples is the dominant trait (D). Your friend has dimples so that means he or she should have at least one allele of the dominant trait to express that trait. So your friend would either be homozygous dominant (DD) or heterozygous dominant (Dd). Notice that there is a recessive allele in the second. Even with that present, dimples would be still expressed.

The failure of the attempt to reintroduce clapper rails in California was an example of the _____.
Lemur [1.5K]

The correct answer is option D, difficulty of redesigning workable ecosystems

Reason -

The area that was redesigned into an ecosystem actually failed to attract the endangered species of clapper rails in California because of the following two reasons –

a) Failed attempt of restoration of Cord grass ( a tree which is a dominant tree in the nesting habitat of clapper rail) . Even if few such trees were there they could not grow to their full height and thus were incapable of providing adequate nesting cover

b) Due to the lack of predatory insect, some herbivore insect in the ecosystem attacked the green grasses thereby making the nesting inadequate.
