Answer:
Demolishing a building involves pulling down the whole structure and building from the scratch while renovation doesn’t involve pulling down the whole structure. It involves pulling down some parts of the building or simply modifying the building.
An advantage of Demolition is that the individual is able to build from the scratch which permits him/her to have the exact structure wanted.
A disadvantage of this is the high cost incurred on demolition and building from the scratch.
An advantage of Renovation is the less cost involved since it only requires some modifications and not total pulling down of the structure.
A disadvantage of Renovation is the inability to get the exact building taste the individual hoped for.
Compartmentalization gives eukaryotic cells advantages over prokaryotic cells, mostly in the efficiency of cellular processes. However, despite the fact that prokaryotic cells lack membrane-bound organelles, they must still perform cellular processes necessary for survival and reproduction. Prokaryotes have internal regions with specialized structures and functions and can often use enzymes in their cell membrane for cellular processes. Prokaryotes and eukaryotes have many cellular processes in common. All but ONE apply.

what does your blood pick up from the cells
Answer:
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.

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.
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.
Hope that answers the question, have a great day!

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.
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.
When a deer hears a sound in the forest such as crackling footsteps it immediately freezes and bolts through the bushes this is an example of the. Response
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.

The replication of DNA is a complicated process during which DNA is occasionally damage. Discuss when in the cell cycle DNA is assessed for damage and predict what effect DNA damage would have on the cell cycle.
Answer:
DNA is first checked during the G1/S. This is when the integrity of DNA is checked to make sure it's correct and ready to be replicated in the S phase. If the DNA fails the check, it can leave the cell cycle or enter a resting phase called G0, where it stays until the DNA is corrected. Any damage is fixed by proteins, the key one being the p53 protein, a tumor suppressor. It works by halting the cell cycle and activating repair proteins. If the damage is irreparable, it initiates apoptosis, programmed cell death, to prevent the damaged DNA from replicating and dividing into cells. If this gene is missing or mutated, damaged cells continue to replicated rapidly and lead to the rise of tumors and thus cancer. If nothing is wrong or the errors are fixed, the G1/S checkpoint gives the green light, to allow DNA to replicate. The now replicated chromosomes are once again checked in the G2 checkpoint. Here, they're checked again for integrity and whether or not replication occurred correctly. If the DNA fails these checks, the cell once again attempts to fix the problems. If these problems aren't corrected due to mutations in the repair proteins, the cells containing the damaged chromosomes will continue to replicate rapidly and cause cancer. Should no problems occur, cyclin dependent kinases (CDKs) are activated and allow the cell to continue into mitosis. DNA damage can basically lead to the rapid division of mutated cells and cancer.

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.
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?
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.
