Which type of cell has a nucleus?
Prokaryotic Cell
Or
Eukaryotic Cell
Answer:
Eukaryotic cell
Explanation:
The cell of living organisms have been classified as either eukaryotic or prokaryotic depending on whether or not it contains a NUCLEUS. A prokaryotic cell is a cell that does not contain a membrane-bound nucleus to house its genetic material e.g bacteria, archaebacteria etc.
On the contrary, eukaryotic cells possess a membrane-bound nucleus that houses their genetic material e.g fungi, animals, plants etc. Based on the above explanation, an EUKARYOTIC type of cell produces a nucleus.

You want to determine whether short wings in fruit flies are the result of a dominant or recessive mutation. You cross a short-winged fly stock with a long-winged fly stock (which is considered to be wild type or / ). The progeny have a 1:1 ratio of short to long wings. You then allow the F1 short-winged flies to mate. The F2 progeny have a phenotypic ratio of 3:1 short to long wings. Short wings are likely the result of:
Answer:
a dominant mutation
Explanation:
A monohybrid testcross is a cross-breeding experiment used to determine if an individual exhibiting a dominant phenotype is homo-zygous dominant or heterozygous for a particular phenotypic trait (in this case, wing length). In a monohybrid testcross, a 1:1 phenotypic ratio shows that the dominant parental phenotype was a heterozygote for a single gene that has complete dominance. Moreover, a 3:1 ratio in the F2 is expected of a cross between heterozygous F1 individuals, which means that 75% of individuals with short wings have the dominant allele that masks the expression of the long-wing trait (i.e. the recessive allele).

The main difference between macroevolution and microevolution is _____.
Select one:
a. the time frame of the evolutionary process
b. the species that evolve during each
c. that microevolution is only for small organisms, and macroevolution is for large organisms
Answer: c. that microevolution is only for small organisms, and macroevolution is for large organisms
Explanation:
Evolution can be defined as the gradual changes that occur in a population of a species or in an individual which supports its survival in the changing environment. Microevolution can be defined as the changes that occur during lifetime in an organism, whereas multiple changes occurring in the organisms over multiple generations. The microevolution is effective over small organisms like insects whereas macroevolution works on large organisms like whale. As the scale of evolution is low in microevolution as small number of changes occur whereas in case of macroevolution the scale of evolution is high so more changes will occur multiple times in an organism.
Answer:
the correct answer is - the species that evolve during each

According to the law of conservation, both energy and matter are conserved in the natural system. Earth as a whole is a closed system, in which energy and matter can move from one sub-system to another.
As energy and matter are transferred between subsystems, different forms of matter and energy interact. For example, during photosynthesis, carbon is transferred from the atmosphere into the biosphere, while radiant energy from the sun is converted into chemical energy.
During this process, the amount of carbon remains constant, but some of the radiant energy is transformed into electrical energy.
What is the Law of conservation?The law of conservation may be defined as a physical property that can not change in the course of time within an isolated physical system.

In a deciduous forest of Maine, there are 300 Falcons living in a certain region at the beginning of the year. Scientists have determined that these Falcons demonstrate exponential growth and that their per capita growth rate is 0.067. What will the population of Falcons be in 5 years?
Answer:
419 Falcons
Explanation:
P= Poe^rt
P= population at time t = ?
Po = initial population = 300
r= growth rate = 0.067
t = time taken = 5 years
P = 300e^(0.067 * 5)

Why do scientists often use bacteria to produce medicines?
Scientists often use bacteria to produce medicines because of their easy use, genetic manipulability, and genetic ability to produce medicine.
What are the characteristics of bacteria?Scientists often use bacteria to produce medicines because bacteria grow quickly and can be cultured in large quantities. This makes them a cost-effective option for production of large amounts of medicine.
Bacteria also have a simple genetic makeup that is easy to understand that allow scientists to easily produce proteins. Some bacteria have the ability to produce natural compounds containing medicinal properties, such as Streptomyces produces several antibiotics that are used in medicines.
Bacteria can also be genetically engineered to produce new compounds that can be used as new medicines. Bacteria are highly versatile for production of wide range of medicines.
Therefore, bacteria are used for producing medicines because of easy use, genetic manipulability, and genetic ability to produce medicine.

What is the main difference between the intertidal zone and the neritic zone?
the amount of exposure to sunlight
the amount of salt in the water
the amount of time covered by water
the presence of plants and animals
Answer:
intertidal zone is the area of shore between the high tide and low tide lines whereas neritic zone is the area of the ocean from the low tide line out to the continental shelf.
The main difference between the intertidal zone and the neritic zone is the amount of time covered by water.
What is intertidal zone and the neritic zone?The intertidal zone is the area of the shoreline that is regularly exposed to air at low tide and submerged at high tide. This area is characterized by its exposure to fluctuations in water level, temperature, and salinity, and is home to a diverse range of organisms that have adapted to these conditions.
The neritic zone, on the other hand, is the shallow ocean water over the continental shelf, extending from the low tide mark to a depth of about 200 meters. Unlike the intertidal zone, the neritic zone is always covered by water and is characterized by relatively stable physical conditions, including a relatively constant temperature and salinity.
While the amount of exposure to sunlight can vary in both the intertidal and neritic zones, the main difference between these two habitats is the amount of time covered by water and the resulting stability of environmental conditions.

According to the World Population Growth graph, which best describes the human population growth after the Industrial Revolution?
Slow growth
Exponential growth
Negative growth
Zero growth
Answer:
negative
Explanation:
According to the World Population Growth graph, the human population growth after the Industrial revolution will be exponential growth. Thus, the correct option will be B.
What is the Exponential growth?Population growth can be defined as the annual increase in the population size of a species. Population growth is the difference between the total births less the total deaths and the difference between immigrants less the emigrants, in a given country, territory or a geographic area at a given year.
Exponential growth of a population is a function which shows an increase within a population that occurs at the same rate throughout the time period. When different populations experience doubling or tripling in numbers, then we can assume the data increases exponentially through the time. The opposite of exponential growth is exponential decay of the population, where the data shrinks rather than it grows.
Therefore, the correct option will be B.
