Answer: a whole chromosome probe is most useful for examining chromosomal abnormalities such as Down Syndrome, miscarriages, and problems with growth and development
Which of the following is the best explanation for why the chromosome numbers above are all even?
Diploid Chromosome Number
Fruit Fly 8
Human 46
Goldfish 94
1)
The diploid chromosome number represents two sets of chromosomes, one from each parent, so it is always an even number.
2)
Animal cells always have an even number of chromosomes, and plant cells always have an odd number of chromosomes.
3)
The number of chromosomes present in a diploid cell doubles for each generation because there are two parents.

why do you think slate might be denser then shale?
Answer:Slate is denser than shale because its atoms and molecules become more compact due to the presence of intense pressure. Due to this event, the minerals are squeezed and realigned in such a way that the axes are directed to where the pressure was applied.

Cómo los avances de la ciencia y la tecnología sin control puede llegar a afectar al ser humano, demás seres vivos y el entorno.
Answer:
nuevas tecnologías y desarrollos científicos muchas veces conllevan un potencial para generar daños irreversibles sobre las poblaciones humanas y el medio ambiente
Explanation:
Los avances científicos y tecnológicos conllevan grandes ventajas para la humanidad y simultáneamente también riegos que pueden producir daños irreparables en las sociedades y el medio que las rodea. Por ejemplo, el dominio de la tecnología basada en el uso de la fisión nuclear ha sido beneficioso para obtener grandes cantidades de energía, pero también este desarrollo conlleva la producción de armamento nuclear que pone en riesgo a las sociedades y al medio ambiente. Otro ejemplo puede estar representado por el uso de la tecnología de edición genómica CRISPR-Cas, la cual ha sido recientemente desarrollada. Esta tecnología ha llevado esperanza para el tratamiento de enfermedades genéticas hereditarias a través de la restauración de la función génica. Sin embargo, la técnica CRISPR-Cas de edición genómica ha sido recientemente utilizada para desarrollar bebés editados genéticamente, aún cuando los efectos secundarios que dicha tecnología no han sido completamente resueltos (efectos de edición genómica en regiones genómicas no deseadas), con lo cual llevando un serio riesgo para los bebés que han sido modificados genéticamente. De este modo, cada avance científico tecnológico debe estar apropiadamente regulado por las sociedades a fin de evitar los potenciales efectos dañinos de dichos avances.

Which nation would be CLOSEST to the command side on this economic
continuum?
O the United States
O the United Kingdom
O France
O North Korea
Answer: D) North Korea
==============================================================
Explanation:
The United States, the United Kingdom, and France are all countries that have capitalistic economies. This means that (for the most part) private industry and the market determines what products are produced and who gets those products. I said "for the most part" because these countries don't follow a purely capitalistic structure. There are some elements of government regulation to ensure that no breakdowns occur. The regulations are also to ensure some level of fairness as well, in addition to preventing things like fraud.
On the other hand, countries like North Korea are known as command economies because the government determines what products are to be made and they determine who gets the products. This means that they set the prices as well to whatever they feel is correct (even if the market may disagree otherwise). The term "communism" is often strongly connected to the term "command economy".

Do dams purify water?
Answer:
I dont think so but i really dont know.
Explanation:
I dont know.
Answer:
Dams that divert water for power and other uses also remove water needed for healthy in-stream ecosystems. Peaking power operations can cause dramatic changes in reservoir water levels. This can leave stretches below dams completely dewatered.

Describe how population studies can be conducted in a school garden
Answer:
Population studies look at factors for one individual species.
Explanation:
In a garden, there are multiple species of plants growing. You could study different factors of each population, which is just all the individuals of one species in an area. For example, you could study how adding fertilizer affects the growth of tomato plants. To do this, you would have some tomato plants in the garden that have fertilizer added to the soil and some that don't. At the end of a certain period of time, maybe a month, measure the plants, find the average height and compare their growth. This is just one example, but there are lots of different things you could study.

How do fungi differ from plants?
Answer:
Plants use sunlight and water to get energy. Fungi eat decayed things.
Explanation:
Also, they are different in two other important ways: 1) fungi cell walls are composed of chitin rather than cellulose (plants) and 2) fungi do not make their own food like plants do through photosynthesis. They are eukaryotic. They get their food by decomposing matter or eating off their hosts as parasites. Like I said above, they eat dead things.
Hemoglobin a protein found in red blood cells, carries oxygen. Abnormal hemoglobin cannot carry as much oxygen as normal hemoglobin. The sequences below show sections of the DNA sequence that produce both the normal and abnormal types of hemoglobin.
Normal DNA sequence: GGA CTC CTC
Abnormal DNA sequence: `GGA CAC CTC
~Write the messenger RNA sequences that would be produced from the normal and abnormal DNA sequences shown above.
~What is the purpose of Transcription?
Answer:
Each subunit surrounds a central heme group that contains iron and binds one oxygen molecule, allowing each haemoglobin molecule to bind four oxygen molecules. Molecules with more oxygen bound to the heme groups are brighter red.

Write down the word and chemical equition of photosynthesis process
Answer:
The photosynthesis equation is as follows: 6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy from light produces glucose and oxygen.
Explanation: (credit to Chris Hall in Quora)
On the geological scale, the equation for photosynthesis would be the opposite of combustion/respiration: carbon dioxide and water molecules converted into oxygen and carbohydrate (or hydrocarbon) molecules (one unit of -CH2O- per CO2).
However, such a simplistic formula is extremely misleading, especially when talking about individual plants and algae instead of macro-geo-chemistry. The oxidation of water to oxygen (aka the light reactions) is a separate (but concurrent) process from the reduction of carbon dioxide to carbohydrate or hydrocarbon (aka the dark reactions). See my answer to a similar question here: Chris Hall's answer to Where is the most detailed chemical structure breakdown of all steps of photosynthesis that is reliable?
Some bacteria, algae, and plant cells only perform one half of the typical photosynthetic pathway, either to produce energy without making sugar/hydrocarbon or to assimilate carbon dioxide using stored chemical energy rather than using light directly (similar to chemosynthesis). And some bacteria do photosynthesis without making oxygen at all, using sulfur in the place of oxygen.
In short, photosynthesis should be thought-of as a series of sequential processes and not as a single chemical reaction.

There are several mechanisms through which reproductive isolation occurs. Which situation is an example of behavioral isolation?
A.
Mules, the offspring of a male donkey and a female horse, are unable to reproduce because they are sterile.
B.
Males of different, closely related species of fireflies signal for mates by flashing different light sequences.
C.
The reproductive organs of snails only properly align when the male and female belong to the same species.
D.
Red and purple sea urchins cannot reproduce with one another because the sperm and egg cannot fuse.
Answer: B. Males of different, closely related species of fireflies signal for mates by flashing different light sequences.
Reproductive isolation refers to the inability of the members of a species to breed with members of other species. Behavioral isolation is a type of reproductive isolation, in which mating between the members of the species is facilitated by their behavior. It helps members of the same species to identity their mates. It prevents mating between population of distinct species.
Males of different, closely related species of fireflies signal for mates by flashing different light sequences is an example of behavioral isolation because flashing of light by fireflies is the behavioral characteristic which shows their desire for mating. The mates identify the light signals flashed by their partner belonging to the same species.
Answer:
B. Males of different, closely related species of fireflies signal for mates by flashing different light sequences.

Directions: Select the correct diagram.
The diagrams below represent the fossils of shellfish in four hypothetical cross sections of a canyon. The top layers are the
youngest layers, and the bottom layers are the oldest
Which cross section could be used as evidence that, over time, a circular shellfish descended from a hexagonal shellfish?
1
2
3
Answer:
The answer is number 4
Explanation:
Cross section 4 contains evidence that a transition from a hexagonal shellfish to a more a rectangular shellfish and then to a circular shellfish may have occurred. These changes would have been gradual, as shown by the position of the fossils in each layer of the canyon.
Although the evidence provided by cross section 4 is strong, more research would be needed to prove a connection among the shellfish in the canyon, such as morphological or
The cross-section in diagram 4 could be used as evidence that, over time, a circular shellfish descended from a hexagonal shellfish. Hence, option D is correct.
What are fossils?Fossils are the remains or traces of ancient living organisms that have been preserved in sedimentary rocks or other materials over long periods of time. Fossils can include bones, teeth, shells, imprints, or other parts of plants and animals that have been mineralized, or turned into rock, over millions of years.
They are important clues to the history of life on Earth, providing evidence of the evolution of different species and the environmental conditions that existed in the past.
Fossils can be studied by paleontologists to learn more about the biology and ecology of ancient organisms, as well as to understand how the Earth's ecosystems have changed over time. Hence, option D is correct.
