Expert Solution

CRAYFISH :-

pair of antennae : 2 (2 antennae, 2 antennule )

body parts : 2 ( the cephalothorax, consisting of the head and upper body and a segmented abdomen)

pair of walking legs: 4 (8 nos)

unique structures: 1 pair of cheliped (claws), 5 pairs of smaller limbs called swimmerets under the tail, no wings, or special jumping legs

GRASSHOPPER :

pair of antennae : 1

body parts : 3 ( the head, the thorax and the abdomen)

pair of walking legs: 3 pairs (6 joined legs)

unique structures: Grasshoppers have 2 pair of wings, their 6 legs are muscular and well suited for jumping, have a small pincher to tear off food.

SPIDER :-

pair of antennae : 0,

body parts : 2 ( a fused head and thorax (called a cephalothorax or prosoma) , abdomen (also called an opisthosoma).

pair of walking legs: 4 (8 nos)

unique structures: pair of appendages in front of legs called pedipalps used to hold prey,they have endoskeleton in addition to their exoskeleton, spiders have no wings, no special legs for jumping.

The robot in Futurama, Bender, has insured several of his body parts. His arms, legs, and head are insured. His policy costs a total of $1000 a year, and pays out $10000 if he loses his legs, $25000 is he loses his head, and $50000 if he loses his arms. (a) List the sample space for the outcomes of Bender’s damages. Note that it is possible he loses both his legs and arms simultaneously, and so on. Sadly, the policy...

The following variances were determined for measurements of body length, antennae bristle number, and egg production in a species of moth. Which of these characters would be most rapidly changed by natural selection? Which character would be most slowly affected by natural selection? Variance Body length bristle # Eggs Total phenotypic variance (VP) 798 342 145 Additive variance (VA) 132 21 21 Dominance variance (VD) 122 126 24 Interaction variance (VI) 118 136 34 Note that characteristics with a high narrow sense heritability value would change most quickly by selection.

Let T be a graph. Suppose there is a unique path between every pair of vertices in T. Prove that T is a tree. Can I do this using the contraposative? Like Let u,v be in T and since I am assuming T to not be a tree this allows cycles to occur thus the paths must not be unique. Am I on the right track?

Aldo's Shoes bought a shipment of 756 pairs of women's shoes for $48 per pair. The store sold 107 pairs at the regular selling price of $159 per pair, 69 pairs at a clearance sale at a discount of 44% and the remaining pairs during an inventory sale at a price that equals cost plus overhead. The store's overhead is 15% of the cost. (a) What was the price at which the shoes were sold during the clearance sale? (b)...

Below are pairs of economic outcomes in (a)-(g). For each pair, provide 1 Determinant Change or 1 Monetary Policy stance (Expan or Contr) or 1 Fiscal Policy stance (Expan or Contr) that could cause the pair of outcomes under the assumptions of: wages are rigid (expect for (g)); secondary effects are smaller than initial effects; international financial account responses are stronger than international current account responses; and default concerns are low. Determinant changes / policies may be repeated. a. Unemployment...
