Explanation:
A jogger jogs from one end to the other of a straight track in 1.13 min and then back to the starting point in 1.63 min. What is the jogger’s average speed in jogging to the far end of the track (assuming the track is 100 m long)
Answer:
Average speed of jogger,s=72.46 m/min
Explanation:
Total distance covered by a body divided by the elapsed time to cover that distance is known as average speed of that body.
We have given length of track=100m
Therefore total distance covered by the jogger,
[tex]d=100m+100m\\d=200m[/tex]
Total time taken by joggers to cover 200m distace,
[tex]t=1.13 min+1.63m[/tex]
t=2.76 min
Therefore average speed of jogger,
[tex]s=\frac{d}{t}[/tex]...............(1)
put values of d and t in equation 1
we got,
[tex]s=\frac{200 m}{2.76 min}[/tex]
average speed of jogger,s=72.46 m/min
N eukaryotes, newly synthesized proteins encoded in genes in the nucleus are found in the _____ and dna are observed in the _____.
Final answer:
In eukaryotic cells, proteins encoded by nuclear DNA are synthesized in the cytoplasm at ribosomes, while DNA is contained within the nucleus. mRNA serves as the intermediary that carries genetic information from DNA in the nucleus to ribosomes in the cytoplasm where it is translated into protein, following the central dogma of molecular biology.
Explanation:
In eukaryotes, newly synthesized proteins encoded in genes in the nucleus are found in the cytoplasm and DNA are observed in the nucleus. Proteins are synthesized at ribosomes in the cytoplasm or on the rough endoplasmic reticulum (RER) after the encoding information is transported from DNA as messenger RNA (mRNA).
The molecular process starts with DNA in the nucleus, where transcription into RNA occurs. Subsequently, this RNA, particularly mRNA, travels through nuclear pores into the cytoplasm. There, ribosomes translate the RNA into proteins in a process called translation. This sequence of events, from DNA to RNA to Protein, is a cornerstone of molecular biology known as the central dogma.
DNA is found within chromosomes and is tightly associated with proteins to form chromatin. Some RNA types, like rRNA and tRNA, are also transcribed in the nucleus and play significant roles in protein synthesis. The organization and regulation of these processes are fundamental to the function and complexity of eukaryotic cells.

C. Conservation Tillage
D. Increased Pesticide Use
Answer:
Conservation tillage.
Explanation:
Tillage refers to agricultural methods that is practiced before growing crops it could be by digging, overturning , ploughing e.t.c.
Conservation tillage is a type of tillage that involve practices which leave the soil undisturbed. It could either be no till I .e the soil is not disturbed at all or mulch uses the chisel to till the soil before planting and ridge till in which the the seeds are planted on a seed beds. This type of tillage conserve the soil by reducing erosion.
Erosion bring about removal of soil tip layer, washing away of nutrients which is important for plants growth. Through conservation tillage soil structure and nutrients are preserved and sustained.
Answer:
c. Conservation Tillage
Explanation:
In this experiment, why didn't we just use ethanol to extract the trimyristin (instead of dichloromethane)? this would have saved us a step and we would have been able to recrystallize directly after filtration.
Dichloromethane was preferred over ethanol for extracting trimyristin due to its nonpolarity and volatility, facilitating an efficient extraction process and easy removal post-extraction. Although ethanol could have simplified the process, it may have resulted in a less efficient extraction and compromised yield and purity due to its polarity.
Explanation:In this experiment, dichloromethane was used rather than ethanol to extract the trimyristin due to certain properties it possesses. The choice of solvent can significantly impact the efficiency of the extraction process.
Primarily, dichloromethane is an excellent solvent for this procedure because it is nonpolar, and can dissolve a wide range of organic compounds, including trimyristin. It is also volatile, which makes it easy to remove by evaporation post-extraction.
On the other hand, ethanol, an alcohol, is a polar solvent, and is less efficient at dissolving nonpolar substances such as trimyristin. Yes, it's true that ethanol could have been used in this experiment, simplifying the process to one-step as recrystallization could be done directly after filtration. However, using ethanol might have resulted in a less efficient extraction due to its polarity, which could compromise the yield and purity of trimyristin obtained.

People with type o-negative blood are referred to as universal donors, although if you give type o-negative blood to any patient you run the risk of a transfusion reaction due to certain antibodies present in the blood. however, any patient can receive a transfusion of o-negative red blood cells. only 9.4% of the american population have o-negative blood. if 12 people appear at random to give blood, what is the probability that at least one of them is a universal donor? (use 4 decimal places.)
The probability that at least one person in a randomly selected group of 12 is a universal donor (type O negative) is approximately 69.6% or in 4 decimal places 0.6959.
Explanation:The question involves calculating the probability of getting at least one universal donor (type O negative) in a randomly selected group of 12 people. We know that only 9.4% of the American population is a universal donor. Calculating the probability involves first determining the probability of not having a single universal donor in the group and then subtracting this from 1 to get the actual probability.
First, calculate the probability that a single individual is not a universal donor, which is 1 - 0.094 = 0.906 (90.6%). This must be raised to the power of 12, because this situation needs to occur 12 times in a row (none of the 12 individuals are universal donors). Mathematically, it is represented as (0.906)^12 = 0.304.
This means there is a 30.4% chance that in a group of 12 people, no one is a universal donor. But, the question asks for the probability that at least one person is a universal donor. So, we subtract this probability from 1 (representing 100% certainty). Thus, 1 - 0.304 = 0.696 or 69.6% (4 decimal places: 0.6959) is the probability that within a group of 12 people randomly chosen, at least one is a universal donor (type O negative).

The probability of at least one of the 12 random people being a universal donor, given a 9.4% prevalence rate of O-negative blood in the population, is 0.5680 or 56.80%.
The probability of at least one person being a universal donor when 12 people appear at random to give blood, given that 9.4% of the American population have O-negative blood, can be calculated using the concept of complementary probability.
This means we first find the probability that none of the 12 people are universal donors and subtract that from 1.
The probability of a person not being a universal donor is 1 - 0.094 (since 9.4% are donors, then 100% - 9.4% = 90.6% or 0.906).
For 12 independent donors, the probability that all are not universal donors would be (0.906)¹².
To find the probability that at least one is a universal donor :
= 1 - (0.906)¹²
= 1 - 0.4320
= 0.5680 or 56.80%
Thus, the probability that at least one person is a universal donor out of 12 random people is 0.5680 (or 56.80%), when rounded to four decimal places as specified.

Which one of the following is the most inclusive category?
A) ecotone.
B) landscape.
C) ecosystem
D) biotic community
The most inclusive category among the given options is ecosystem.
Explanation:The most inclusive category among the given options is ecosystem. An ecosystem includes all living organisms in a given area, along with the nonliving environment. It encompasses multiple populations, communities, and interactions between biotic and abiotic factors. An ecosystem encompasses everything in a particular area or environment. It includes not only all living organisms (plants, animals, microorganisms) but also the nonliving components like air, water, soil, sunlight, temperature, and minerals. This holistic approach considers the intricate interrelationships between living (biotic) and nonliving (abiotic) factors.
Final answer:
The most inclusive category among the given options is landscape, as it encompasses multiple ecosystems and includes a variety of biological and physical components. So the correct option is B.
Explanation:
The question asks for the most inclusive category among the given options. To determine this, we need to understand the hierarchy of biological organization. An ecosystem consists of all the living things in a given area, together with the nonliving environment, including abiotic factors such as water, minerals, and sunlight. On the other hand, a biotic community contains all the populations of different species that live and interact in the same area. A landscape includes a range of ecosystems and can consist of protected areas, private lands, and a diversity of habitats. Lastly, an ecotone is a transition area between two biomes. Based on this information, the most inclusive category is B) landscape because it encompasses multiple ecosystems and the variety of biological and physical components they include.
