Answer:
4.26
Explanation:
Let the green-melon parents be Gg, then we expect the cross with the yellow-melon plant gg so as to produce 50% Gg and other 50% of gg offspring. What we observed was that 53 green and a 41 yellow. Based on the total number of 94 offspring , we expected half and a half ratios to be 47 of each color.
Observed(o) Expected(e) (o-e) [tex]$(o-e)^2$[/tex] [tex]$(o-e)^2/e$[/tex]
Green-melon plant 53 47 6 36 0.766
Yellow-melon plant 41 47 -6 36 0.766
Therefore the chi-square value is 1.53 which is less than the critical value of 3.84. Therefore, the null hypothesis is accepted.

Which organisms are secondary consumers in a temperate coniferous forest?
Complete question:
Which organisms are secondary consumers in a temperate coniferous forest? Select all that apply:
moose lynx wolf elkAnswer:
The lynx and the wolf are the only secondary consumers on the list.
Explanation:
In the trophic web, the energy transference occurs when each organism feeds on the preceding link and is eaten by the following link.
The first ones are the autotroph organism or producer, such as a vegetable, that can synthesize organic matter from inorganic matter.
The following links are the consumers: herbivores are primary consumers and feed on producers. Carnivores are secondary consumers and feed on herbivores, and so on. The last links are the decomposers, microorganisms that act on dead animals degrading organic matter.
According to the definition of secondary consumers, among the animals on the list, we can assume that the lynx and the wolf are the only secondary consumers. They are both carnivores and feed on herbivores.
On the other hand, the moose and the elk, are both first consumers.
Answer: Wolves
Explanation: Wolves eat primary consumers like rabbits, Lynx are also secondary consumers!

A scientist is studying metabolic rate in a Giant Hummingbird in Peru. The scientist assumes a captured individual has been feeding on nectar (glucose) recently, but in fact the individual has not fed in the last hour and is currently metabolizing fat (palmitic acid). 3. Calculate the measurement error the scientist would introduce based on their faulty assumption if the scientist were measuring CO2 production. Will the scientist over- or underestimate metabolic rate
Answer:
Yes.
Explanation:
Yes, the scientist underestimate the metabolic rate of Giant Hummingbird. The scientist experience the measurement error due to non-feeding of Giant Hummingbird that leads to faulty assumption when the scientist were measuring CO2 production because the Giant Hummingbird breakdown the fats of the body for the release of energy instead of glucose. There is difference in the production of carbondioxide rate due to difference in the composition of fats and glucose.

Your friend runs out of gas and you have to help push his car. Discuss the sequence of bones and joints that convey the forces passing from your hand, through your upper limb and your pectoral girdle, and to your axial skeleton.?
Answer: The sequence of bones and joints that convey the forces include: From metacarpal bones --> carpal bones --> midcarpal and radiocarpal joints --> radius and ulna bones --> elbow joint --> humerus --> glenohumeral joint --> scapula --> acromioclavicular joint --> clavicle --> sternoclavicular joint --> sternum.
Note: the sign (-->) represents "into the".
Explanation:
The skeletal system is made up of bones of the skeleton, their joints and the skeletal muscles which acts together to bring about different movements in the body. The skeleton of a vertebrate had the following basic plan:
--> The axial skeleton: this forms the main central axis. This is made up of the skull,vertebral column, breastbone (sternum), and ribs.
--> The appendicular skeleton: this consists of parts that articulates with the axial skeleton. This is made up of the forelimbs, hindlimbs, pelvic and pectoral girdles.
From the question given, in an attempt to help push the friend's car, the sequence of bones and joints that convey the forces will pass from METACARPAL BONES of your hand into the CARPAL BONES at the base of your hand. Forces will then pass through the MIDCARPAL and RADIOCARPAL JOINTS into the RADIUS and ULNA bones of the forearm. These will pass the force through the ELBOW JOINT into the HUMERUS of the arm, and then through the GLENOHUMERAL JOINT into the SCAPULA. The force will travel through the ACROMIOCLAVICULAR JOINT into the CLAVICLE, and then through the STERNOCLAVICULAR joint into the STERNUM, which is part of the axial skeleton.
As one pushes against the car, the forces will pass in a sequential manner from the bones of the hand to the bones that are part of the axial skeleton.
• Forces will pass from the metacarpal bones of the hand into the carpal bones at the base of the hand, when one pushes against the car.
• After that the forces will then mediate via the radiocarpal and midcarpal joints into the ulna and the radius bones of the forearm.
• Then the force will move via the arm's humerus, and then via the glenohumeral joint into the scapula.
• The force then will mediate via the acromioclavicular joint into the clavicle, and then via the sternoclavicular joint into the sternum, that is, the part of the axial skeleton.
Thus, in the given case, force gets mediated through the bones of the hand and towards the bones of the axial skeleton in a sequential manner.

Having investigated the impacts of the European Green Crab on the intertidal zone community, the Department of Fish and Wildlife is considering using parasitic barnacles (Sacculina) to control the crab. Given what you know about the importance of species interactions to community structure, what would you suggest should be learned about this parasitic barnacle species before it is introduced into the intertidal community you have been studying
Answer:
Method of controlling the population of crabs.
Explanation:
The method of controlling the crabs by parasitic barnacle species I suggest should be learn before its introduction because this method provides valuable knowledge about the method the parasitic barnacle species control the crabs population. This barnacle species is a parasite that feeds on the crabs, it controls the population of crab by not killing the crabs but attack on the reproductive part of the crabs that leads to infertility and as a result the population of the crabs are decreases and controlled.
You are studying a new gene "X" that you think controls skin color in Bearded Dragons. In order to determine what gene X does you need lots of gene X DNA to work with. So, you decide to amplify it through the process known as PCR. You have a forward and a reverse primer that have been designed to gene Xf – a gene in frogs that is similar to the one found in the Bearded Dragon. You are pretty sure that these two primers will work in Bearded Dragons, so you decide to go ahead with the PCR. In frogs, the Forward Xf primer binds gene Xf between nucleotides 32 and 47. The Reverse Xf primer binds between nucleotides 1110 and 1135. What size PCR product would these two primers create if they amplified the frog gene Xfp
Answer:
The correct answer is - 1103 bp.
Explanation:
PCR or polymerase chain reaction is a process that uses a primer to amplifying the desired segments of DNA molecules. It is a technique that can amplify a million copies of the DNA segment.
given:
forward primer binds from - 32 to 47
reverse primer binds from - 1135 to 1110
PCR product would be between - 32 to 1135
So, product size would = 1135-32 = 1103.
Thus, the correct answer is - 1103.

Since 1953, when Tenzing Norgay and Edmund Hillary reached the summit of Mount Everest, many climbers have attempted to scale the world's two highest mountains, Everest and K2. Norgay and Hillary aided their climb by bringing supplemental oxygen in tanks, and some later groups have attempted to outdo the originals by trying the ascent without supplemental oxygen. From 1978 to 1999, in fact, 159 teams have attempted to climb Mount Everest or K2. The numbers of individuals who either survived or died during those attempts are given in the following table (data is hypothetical and not the exact numbers observed by Huey and Eguskitza 2000).

k. Tendon 10. The cordlike part that attaches a muscle to a bone
l. Transverse (T) tubule reticulum 1. Membranous channel extending inward from muscle fiber membrane
Explanation:
A muscle has around it epimysium, which is connective tissue. Inside the epimysium, there are fascicles, and around each of them, there is perimysium. Inside every fascicle, there are muscle fibers, each of them is surrounded by a connective tissue called endomysium. Between every muscle, there is also connective tissue and is called fascia. The connective tissue has vessels and provides support.
The muscle cells are called fibers. They have a membrane, the sarcolemma, a cytoplasm, the sarcoplasm, and a sarcomere, which is the functional unit of the fiber, in other words, it is the structure responsible for the contraction. The sarcomere has different bands made of thick filaments of myosin and thin filaments of actin. They are the light and dark striations that go from disc z to disc z when we observe the sarcomere under a special microscope. The sarcoplasmic reticulum is the place that stores the calcium necessary for the contraction of the fiber, and the transverse tubule reticulum allows the contraction of various fibers since they spread the action potential amongst fibers.

In wild populations, evolution is often caused by natural selection. Based on what you have observed, how does natural selection occur?
Answer:
Organisms with heritable (genetically determined) features that help them survive and reproduce in a particular environment tend to leave more offspring than their peers. If this continues over generations, the heritable features that aid survival and reproduction will become more and more common in the population.
