George Box, a famous statistician, once said, "All models are wrong, but some are useful.” What did George Box mean by this statement?
Answers
Answer:
The 2nd part, "But some are useful" - simplifications of reality can be quite useful. They can help us explain, predict and understand the universe and all its various components. The idea of this quote is that every single model will be wrong, meaning that it will never represent the exact real behaviour.
George Box, a famous statistician, once said: "All models are wrong, but some are useful" he made an aphorism stating that mathematical models are flawed.
What is an aphorism?Maxim or sentence that, in a few words, explains a rule or principle of moral significance; apothegma, saying. “Short and succinct text, foundation of a fragmentary and unsystematic style in philosophical writing.

Which statement best descrſoes photosynthesis?
a. when plants produce their own water
b. when plants produce their own sugar
C. when plants produce oxygen and carbon dioxide
d. when plants self-pollinate
Answers
Answer:
b. when plants produce their own sugar
Explanation:
Let's look at the products of photosynthesis! During the process of photosynthesis plants break apart the reactants of carbon dioxide and water and recombine them to produce oxygen (O2) and a form of sugar called glucose (C6H12O6).
Glucose provides plants with needed food through a process called photosynthesis. This process helps plants convert the energy they take in from sunlight into sugar to nourish the plant. Photosynthesis occurs when carbon dioxide, water and sunlight are combined. Plants use these to form glucose and oxygen.

HIV replication requires conversion of the genomic RNA present in the infecting virus to a double stranded DNA that integrates into a human chromosome. Unlike DNA polymerase, HIV reverse transcriptase catalyzes DNA chain elongation from either a DNA or RNA template. Azidothymidine (AZT) was the first effective drug used to inhibit HIV reverse transcriptase and went into clinical use in 1987 to treat AIDS. What best describes how AZT inhibits reverse transcriptase
Answers
Answer:
AZT inhibits reverse transcriptase enzyme.
Explanation:
AZT inhibits reverse transcriptase enzyme that is used by the virus to make a DNA copy of its RNA. This Azidothymidine prevent reverse transcriptase enzyme from doing its function properly. Due to absence of this enzyme, the HIV virus is unable to make copies of its DNA and this Azidothymidine stops the life cycle of the virus and slows the growth of AIDS disease so that's why this drug was considered effective against HIV virus and used in the treatment of AIDS disease.

A red flowered plant (RR) is crossed with a white flowered plant (WW) and produces plants with pink flowers (RW). If two pink flowered plants are crossed, what color offspring could be produced
Answers
Answer:
It would be 100 % pink.
Explanation:
Pink and Pink make Pink. Just as Red and White make Pink.
Due to incomplete dominance, when two pink flowered plants are crossed, the color of offspring could be 1Red: 2Pink :1White.
What is incomplete dominance?In some cases it happens that a certain characteristics does not match with either of their parents, rather it shows new traits.For example: snapdragon.When parent generation of red flowered plant (RR) is crossed with a white flowered plant (WW), F1 produces plants with pink flowers (RW). it does not resembles either of their parents.And when F1 was self pollinated: RW x RW, it produces 1 RR: 2RW: 1WW.Hence, the offspring will be 1 Red flowered plant: 2 Pink flowered plant :1 White flowered plant.

Explain why mining has such a large impact on the environment.
Answers
Answer:
Mining has a large impact on the environment because minerals are contained within the Earth. Earth must be removed in order to extract the minerals. When the minerals are close to the surface, the earth is removed, causing destruction to the shape of the land and the flora and fauna living in that area.

Answers
Answer:
1 AB:1 A
Explanation:
Ia Ia
Ib IaIb IaIb
i Iai Iai
i represents type O blood which is always recessive
the capital I represents co-dominant traits (a or b)
Iai is type A because O is recessive and will be masked by Ia
IaIb is type AB because both capital I traits will be codominant
This cross ultimately gives a 1:1 ratio of type A to type AB

Answers
Answer:
A. Homologue.
B. Chiasma.
C. Synaptonemal.
D. Synaptonemal.
E. Synapsis.
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
Synaptonemal complex can be defined as a network of proteins that is responsible for holding homologous chromosomes (homologues) together.
Generally, a synaptonemal complex (protein lattice) is formed between homologous chromosomes during mitosis and meiosis. Also, synaptonemal complex is important for the formation of the four sister chromatids referred to as tetrads.
Furthermore, the synaptonemal complex (protein lattice) has a tripartite structure which comprises of the following components;
I. SC protein-1 (SYCP1).
II. SC protein-2 (SYCP2).
III. SC protein-3 (SYCP3).
In conclusion, the synaptonemal complex plays a significant role in synapsis, recombination and chromosome pairing.
Matching the various terminologies in genetics with their description, we have;
A. Homologue: one of a pair of chromosomes with similar genetic information and from different sources like the sperm and egg.
B. Chiasma: several X-shaped structures may be visible under the microscope and indicate where crossing over has occurred.
C. Synaptonemal: a lattice of protein holds two replicated chromosomes in precise register with one another.
D. Synaptonemal: four chromatids are held together by a zipper-like structure.
E. Synapsis: a process in which pairs of homologous complex chromosomes line up side by side.

Suppose you travel to a tropical place like the Bahamas and watch the coastal poikilotherms, such as fish, crabs, and starfish, swim and crawl about in the warm waters. Suppose then that you travel to northern Maine and watch the related species of poikilotherms in the cold waters there. It would not be unreasonable to expect to see the animals in Maine moving about in slow motion compared to those in the Bahamas. In fact, however, rates of locomotion are likely to look to your eye to be more similar than different in the two places. Design experiments to assess whether the Maine animals are especially able to be active in cold waters. If you find that they are, how might their high ability for activity in cold waters be explained
Answers
Answer:
The correct answer is -
exposure of the opposite environments to the species and see if they are able to be active in cold waters.
If they are then species of organism in Maine and could have more ice-nucleating agents which are responsible for their high ability for activity in cold waters.
Explanation:
To test the assess if the Maine species of organisms are especially able to be active in cold waters an experiment can be designed where one needs to place the species or animals from Maine and Bahamas in reverse conditions.
Maine animals are placed in warm water environments and species from the Bahamas can be placed in cold water. Finding if they are able to adapt in reverse condition by calculating various processes and motion, if yes then it shows that it is not a special ability to survive in cold temps. However, if it is not then the Maine poikilotherms are specially designed for their environment. In case of yes then species of organism in Maine and could have more ice-nucleating agents
