when crustaceans such as crabs are kept in seawater with a lower than normal PH, ATP-repuiring pumps that maintain ion gradients in the animals bodies significantly increase their activity in comparison with normal levels. Explain how the increased use of atp by these pumps will most likely affect the ability of the animals to carry out other metabolic reactions such as that catalyzed by PFK. Hemolymph is the fluid in the red king crabs body that surrounds its cells and is typically slightly hyper tonic to the seawater. explain how the crabs gained weight during this procedure

In order to clone adult animals, scientists typically begin with a(n)

In pea plants, the allele for inflated pod seed, i, is dominant over the allele for constricted pod seed, i. the punnett square shows a cross for this trait. which offspring will be homozygous dominant

Use this dichotomous key for insect identification to identify the insect shown. 1. a. insect has one pair of wings. order diptera b. insect has two pairs of wings. go to #2 2. a. front wings thicker in texture than hind wings go to #3. b. front and hind wings are same texture throughout. go to #4 3. a. front wings are short order dermaptera b. front wings cover entire abdomen order coleoptera 4. a. wings with scale on all parts of their area. order lepidoptera b. wings without scales go to #5. 5. a. hind wings smaller than front wings. order ephemeroptera b. front and hind wings nearly equal in size. order odonata the insect pictured is in the order diptera. ephemeroptera. coleoptera. odonata.
