Picture the morphology of an average soapberry bug from a rain tree population and compare it to the morphology of its new food source, balloon vine seeds. This average bug was taken from a population containing a range of sizes. (a) Are large, small or average bugs more likely to have relative fitness on the new food source?(b) List one change in bug morphology that you would reasonably expect in bug populations that have been living on golden rain trees. (c) List one change in behavior that you would reasonably expect in bug populations that have been living on golden rain trees.(d) Soapberry bugs are small relative to their host plants, and the bugs vary in their abilities to disperse. Although they have wings, many soapberry bugs have developed flight muscles and walk more often than they fly. In davis, where both balloon vines and golden rain trees are grown, would a dispersing bug likely have higher fitness than one with less developed flight muscles? Explain your answer.
Answers
Answer:
(a) In this case, small bugs are more likely to have relative fitness on the new food source.
(b) A change that will occur in bug morphology is that the female bugs will turn out to be the same size as the male bugs.
(c) In terms of behavior, the bugs will experience less competition towards reproducing early.
(d) Yes, the dispersing bug would have higher fitness as they will be able to easily get access to new resources once the previous one has run out, whereas the bugs with less developed fight muscles will not be able to do so.

Answers
Answer:
Conditioned response
Explanation:
When a stimulus is generated on the basis of learning behaviour of an individual then it is known as conditioned response. While unconditioned responses are produced naturally.
In this question, when the deer heard the crackling noise, he could relate it with the upcoming danger and hence in order to save himself he hides behind the bushes.

All cells need energy to live. How do the organelles in the plant cell above work together to get and use this energy?
A.
The nucleus makes energy from materials in the cell, and the vacuole stores this energy until the cell needs to use it.
B.
Chloroplasts make food using energy from the Sun, and mitochondria break down this food to release energy for the cell.
C.
Mitochondria take in food from the environment, and the nucleus breaks down this food to release its energy to the cell.
D.
The vacuole takes in energy from the environment, and chloroplasts change this energy into a form the cell can use.
Answers
Answer:
B
Explanation:
Glucose and other carbohydrates made by plants during photosynthesis are broken down by the process of aerobic cellular respiration (requires oxygen) in the mitochondria of the cell. This releases energy (ATP) for the cell. Because they break chemical bonds of glucose to release energy to do work in a cell.
Chloroplasts make food using energy from the Sun, and mitochondria break down this food to release energy for the cell. Thus, the correct option is B.
How do the organelles work in a plant cell?
Plant cell organelles are the specialized organelles which help to maintain the structure of the plant cell, such as the water containing vacuoles and the rigid cell wall which is made up of cellulose. The chloroplasts in the plant cell are the organelles that contain chlorophyll pigment and allow plant cells to do photosynthesis and produce carbohydrate.
Glucose and other carbohydrates (sugars) are made by plant cells during photosynthesis are then broken down by the process of aerobic cellular respiration which requires oxygen molecule in the mitochondria of the plant cell. This releases energy in the form of ATP for the cell. Because they break the chemical bonds which are present in the glucose molecule to release energy to do work in a cell.
Therefore, the correct option is B.

In flies dumpy wings and ebony bodies are each mutations recessive to wild type, and you expect them to behave in a Mendelian fashion. A dihybrid cross between two animals, each heterozygous for dumpy wings and ebony bodies (DdEe X DdEe) is performed with the following results:
Wild type wings; wild type body 473
Wild type wings; ebony body 156
Dumpy wings; wild type body 149
Dumpy wings; ebony body 52
You will ultimately explain these results using a Chi-squared test.
(a) Begin by setting up a Punnett Square to predict the phenotypic classes and ratios. Use the results of the Punnett square to form a hypothesis on phenotypic ratios.
(b) Perform the chi-squared analysis. Show work.
(c) What conclusion can be drawn from this analysis?
Answers
Answer:
See the answers below
Explanation:
Assuming that D (d) represents the allele for wing type and E (e) represents the allele for body type, crossing DdEe with DdEe will yield the following offspring according to the Punnet's square (see the attached image):
(a) 9/16 D_E_ wild type
3/16 D_ee wild wing, ebony body
3/16 ddE_ dumpy wing, wild body
1/16 ddee dumpy wing, ebony body
(b) Chi square [tex]X^2[/tex] = [tex]\frac{(O - E)^2}{E}[/tex], where O = observed frequency and E = expected frequency.
Phenotype O E [tex]X^2[/tex]
Wild type 473 9/16 x 830 = 466.875 [tex]\frac{(473 - 466.875)^2}{466.875}[/tex] = 0.08
wild w/ebony b 156 3/16 x 830 = 155.625 [tex]\frac{(156 - 155.625)^2}{155.625}[/tex] = 0.0009
Dumpy w/wild b 149 3/16 x 830 = 155.625 [tex]\frac{(149 - 155.625)^2}{155.625}[/tex] = 0.28
dumpy w/ebony b 52 1/16 x 830 = 51.875 [tex]\frac{(52 - 51.875)^2}{51.875}[/tex] = 0.0003
Total [tex]X^2[/tex] = 0.3612
Degree of freedom = 4 - 1 = 3
Tabulated value of [tex]X^2[/tex] (0.05)= 7.815
(c) Since the calculated Chi square value is less than the tabulated value, we conclude that the observed outcome agrees with the expected outcome and that the cross followed the standard Mendelian pattern.
Explain how the boss at the company in the following scenario could have delegated the tasks more appropriately : Samuel and Martha work at the same agricultural consultation company . Samuel works in agricultural quality control, while Martha is an agricultural logistics specialist . A new boss delegated Martha to negotiate a financial deal with a farm and then create a strategy for the farm.
Answers
Answer:
The new boss take the right decision.
Explanation:
The new boss sent Martha to the farm for the financial deal and strategy for the farm is the right choice because Martha is a specialist in agricultural logistics which has good management skill that is required by the task in the farm. Samuel is not a good choice for sending him to the farm because he works in agricultural quality control which is different from the job of Martha.

Which statement describes the ability of the cell membrane to allow various substance to move through it?
The cell membrane is selectively permeable.
The cell membrane is composed of lipids and phosphates.
The cell membrane is both hydrophilic and hydrophobic.
The cell membrane is a bilayer structure.
Answers
Answer:
the cell membrane is selectively permeable
Explanation:
hope that helped
The statement that is the cell membrane is selectively permeable is the statement, which describes the tendency of the cell membrane to permit various substances to move through it.
• The cell membrane comprises a phospholipid bilayer with proteins embedded in it. These proteins perform a number of functions, and the most important function it performs is that they regulate what moves out and what moves in the cell.
• The membrane is selectively permeable as the substances do not pass through it indiscriminately.
• Some of the molecules like oxygen and hydrocarbons can pass through it, while some of the large molecules like glucose and sugars cannot pass through it.
Thus, the cell membrane is selectively permeable.

Waste
Explanation:
The blood brings necessary things, like oxygen and nutrients to the cells. After the cells are given these things, the blood picks up waste products, such as carbon dioxide or excess water, and delivers it to certain areas to be removed from the body. For example, carbon dioxide is brought to the lungs by the blood, so it can be exhaled out.
