The answer is below
Explanation:
The weight of trees is calculated using the equation:
[tex]W=b_o+b_1(D^2H)[/tex]
Where W is the weight in tons, [tex]b_o \ and\ b_1[/tex] are constants , D is the diameter of the tree in inches and H s]is the height of the tree in feet.
The circumference = 14 inches. But circumference = 2πr, where r is the radius and π = 22/7. Therefore:
14 = 2(22/7)× r
14 = (44/7)×r
r= 14 × 7 / 44 = 2.23 inches
Diameter = 2r = 4.45 inches
[tex]W=b_o+b_1(4.45^2*120)\\W = b_o+2381b_1\\Let\ us\ assume\ b_o = -34.671,b_1=1.859.\\Therefore\\W = -34.671+2381(1.859)\\W=4392 \ tons[/tex]
(05.05 MC) Exposing human subjects to experimental manipulations such as high levels of toxins is unethical. We often use model organisms for this reason. What attributes would you look for in selecting a good model organism for investigating the impact of toxins in humans? A good model organism should be able to be easily maintain in the laboratory, be fast growing, with a fast generation time and be as closely related to humans as possible. Cost is the only consideration in selecting a model organism, since all living things are made of cells anything found will apply to humans. The best choice will must be the very closely related to humans, such as chimps, since anything found in other species will not apply to humans. The most important consideration in selecting a model organism is how the public will feel about doing experiments on that species, so the best choice would generally be a very simple organism like bacteria that people don't care very much about.
Answer:
A good model organism should be able to be easily maintain in the laboratory, be fast growing, with a fast generation time and be as closely related to humans as possible.
Explanation:
The attributes that should be looked for in the selection of good model organism for investigating the impact of toxins in humans include:
Easy maintenance: The easier the maintenance of the organism, the better for both the research and the researcher. More can be achieved with less effort as opposed to high maintenance animals.Fast generation time: They should be able to grow and reproduce quickly so as not to prolong the experiment for too long. The lower the regeneration time, the shorter the time required to obtain adequate data for the research.Genetical similarity to humans: A good model organism for humans related study must share some similarities with humans at the genetic level. The more the genetic similarity, the more applicable the outcome of the research on humans.Hence, a good model organism should be able to be easily maintained in the laboratory, be fast-growing with a fast generation time, and be as closely related to humans as possible.

Endometriosis occurs when endometrial tissue, which normally grows inside the uterus, grows outside the uterus. Based on the model, what effects would you expect these growths to have on the female reproductive system and on fertility?
Answer:
Endometrosis could negatively affect the probability of gestating an embryo if they are growing inward. The affection of the fallopian tubes and the uterus could alter the implantation or even generate complications for the embryo during pregnancy.
In addition, endometriosis generates painful conditions in the abdominal area to the point that it is considered as menstrual cramps during menstruation, women who suffer from this disease suffer a lot during the menstrual cycle.
Regarding the reproductive system, those female reproductive systems that suffer from this disease are considered potentially malignant, since many malignant neoplasms are incited to appear in these foci of excessive proliferation of the endometrium.
Explanation:
Endometriosis can affect the walls of the fallopian tube and the uterus, since it occurs in the endometrium, that is why it bears that name.
The macroscopic appearance of this lesion at the histological level is a tumor nodule, since they are proliferative foci.

Cave-dwelling catfish and cave-dwelling earthworms both lack pigmentation and their eyes are reduced or absent. The most recent common ancestor to these organisms had normal pigmentation and fully developed eyes. The similarities between cave catfish and cave earthworms are an example of
Answer:
Analogy
Explanation:
Cave catfish and cave earthworms can be said to have analogous traits, which have over the years developed separately and have different ancestral origins. This new analogous trait is as a result of the need for both organisms in their different environments, which seem similar in condition, to adapt well.
Through convergent evolution analogous structures and traits are usually formed or observed in organisms that do not share the same ancestral origin.

In the autumn, many birds will collect seeds and then hide them in various caches throughout their habitat. The birds will guard their caches from other birds, and move the caches if they start to dry out. These caches provide a food source for the birds during the winter. What is an abiotic factor that contributed to the evolution of this set of behaviors? A. being preyed upon by larger birds B. competition with other birds for space C. limited food availability D. cold winter climate
Answer:cold winter climate
Explanation:During winter specially in the eastern and western part of the world....snows bury grounds and food that enables this organisms live....and cold can also affect them
Answer:
Answer: c. limited food availability
Explanation:
Both biotic and abiotic factors are responsible for shaping the evolutionary framework of the population. Resource availability can be one of the important abiotic factor in determining the evolutionary dynamics of the population or species. Limitations in resource can result in increase in competition. According to population exclusion principle when two species compete for the same limiting resource this results in co-evolution of both the species. But the extent of evolution may vary among the species. The one which undergoes more favorable evolution will be stronger competitor and drive more resources and will be fit for survival in adverse limiting conditions.

What molecule is required each time the myosin head detaaches from one site and reattaches to another
Answer:
The adenosine triphosphate (ATP) molecule
Explanation:
The actin filaments are often associated with myosin to produce muscle contraction. These myosin filaments are considered to be 'molecular motors' capable of converting the chemical energy contained in the ATP molecule to mechanical energy, thereby producing cell movement. Myosin heads bind to actin filaments in order to generate a power stroke. When the adenosine triphosphate (ATP) molecule binds to myosin, the myosin head detaches to the actin filament. During this process, the ATP molecule is broken down and then the released energy is used by the myosin filament to return to its original position.
