Answer:
to provide optimum temperature..
Explanation:
The main purpose of the incubator in this experiment is to provide favorable temperature to the microorganisms. Incubator is a device which is used for rearing the useful microbes such as bacteria and fungi etc. This incubator provides a close environment where temperature of the environment is constant. These useful microbes are very sensitive to external temperature so incubator is used as a growing medium. In this experiment, milk is kept in incubator in order to convert into yogurt by the action of beneficial bacteria. Change the temperature of the incubator in order to find the optimal temperature for the bacteria converting the milk into yogurt.
As Hite and Seitz (2016) discuss in Chapter 5: Climate Change, reputable scientific studies continue to show that the Earth is warming at an unsustainable rate because of a rise in the release of CO2 and methane gases. What is the relationship between population increases and climate change
Answer:
See the answer below
Explanation:
The relationship between climate change and increased population of humans is a direct one. As the population of humans increases, their activities leading to the release of greenhouse gases such as CO2 and methane also increases. The greenhouse gases are primarily responsible for the warming of the earth.
As more and more greenhouse gases are released into the atmosphere, more radiation from the sun is trapped in the atmosphere and the earth receives more warmth. This extra heat received leads to increase in the global temperature, a phenomenon known as global warming. As the average global temperature increases, climate becomes more erratic and unpredictable.
The greenhouse gases-related activities of humans that are bound to increase with the increase in population include deforestation, fossil fuel burning, industrialization, etc.
Which of the following is not a possible environmental consequence of urban sprawl?
a.
deforestation
b.
pollution
c.
loss of natural resources
d.
none of the above
The correct answer is D. None of the above
Explanation:
Urban sprawl or the expansion of human settlements such as cities has multiple negative consequences on the ecosystems. This includes deforestation because trees are usually cut to build houses and other human structures. Indeed, most threes and plants are removed for human construction. This also implies a loss of natural resources that include a wide variety of plants, animals, and even water as nearby bodies of water might be polluted. Besides, this general pollution increases in the area this includes noise pollution, water pollution and air pollution that result from human activities. Thus, all are possible consequences of urban sprawl; therefore, the correct answer is none of the above.
As a health care professional, why do eukaryotic parasites need to be reported within 7 days instead of immediately
Answer:
Because there will be no trace of any infection before 7 days because eukaryotic parasites start spreadinv in 7 days and lasts till one month.
Explanation:
Eukaryotic parasites needed to be reported after 7 days because they start spreadinv in 7 days after exposure and last till one months. Before 7 days there won't be any trace of eukaryotic parasites because they will not have start spreading by then because eukaryotic parasites grow slowly that prokaryotic parasites so there will be slower disease progression.
Most damage caused by eukaryotic parasites is due to their growth inside host cell and eukaryotic infections are difficult to treat because their physiology is similar to that of man.
Eukaryotic parasites are parasites that live inside their host causing damage and having nucleus and membrane bound organelles.

Slowing Down Global Warming As Hite and Seitz (2016) discuss in Chapter 5: Climate Change, reputable scientific studies continue to show that the Earth is warming at an unsustainable rate because of a rise in the release of CO2 and methane gases. What is the relationship between population increases and climate change
Answer:
The increasing level of all the facilities like transportation, production, human waste, and developing new spaces for human beings among others are some of the most essential features of climate change. Thus, the demand for novel products, space, and facilities would also enhance with the increase in the population. This signifies that with the enhancement in the facilities, the environment would get influenced, which would eventually influence the climate.
There would be more emission of carbon dioxide and thus more pollution would develop with the increase in the population of human beings, this further would add up in climate change and global warming. Thus, there is a need in the control of the human population, however, technology is also important in helping humans to sustain a better life. This technology should be advanced and well-equipped so that our climate and environment exhibits no deleterious effects.
Novel technologies like the use of renewable energy, green building, prudent application of resources, and others would also assist the humans in sustaining the environment.

Had it been inoculated in the way as described in the question statement, the bacterial growth would have covered all of the agar plate and we would not have been able to distinguish individual colonies of bacteria. 1 mL is too much of a sample volume to use in cases like these.
The table shows the distribution of traits (A-E) in six extant species (1-6). A "0" indicates the ancestral condition. A "1" is the derived condition. How would you construct a cladogram using these data?
Answer:
The order in the cladogram is the following:
4 > 5 > 3 (taxon 3 share a node with taxon 5)
>6 >1 (taxon 1 share a node with taxon 6)
>2
Explanation:
In this example, taxon 4 is the most basal in the group and taxon 2 is the terminal taxon (i.e., the most recent). Each taxon is a branch of the cladogram tree.
A cladogram is a cladistic tree that exhibits relationships among groups of organisms. A cladogram may have an evolutionary meaning, and therefore evolutionary relationships may be inferred by using this tree. The values 1 and 0 are states of the character and they are used to infer associations in the cladogram. Each branch in the cladogram is referred to as clade, which includes a common ancestor with all its descendants.

Which type of mutation occurs only in gametes?
germline mutation
somatic mutation
point mutation
frameshift mutation
Answer:
Germline mutation
Explanation:
A germline mutation is a genetic change produced in the gametic-germline cells (i.e., male and female gametocytes). The mutations in the germline are inherited in the next generation, while changes in somatic cells are not inherited. Moreover, the germline mutations may occur either before the fertilization or during embryonic development (zygote morula, blastula and gastrula). This type of mutation may be induced by both endogenous (e.g., oxidative DNA damage) and exogenous (e.g., exposure to UV light) factors.
The type of mutation that occurs in gametes only is : ( A ) Germline mutation
Germline mutation is a type of mutation that occurs in the gametocytes ( male and female ) and is passed( inherited ) on to the offspring ( next generation ). while mutations occurring in somatic cells are not passed on to the next generation .
Germline mutation is induced by either endogenous factors or exogenous factors and this is because Germline mutations can occur before fertilization or after fertilization.
Hence we can conclude that the type of mutation that occurs in gametes only is Germline mutation.

Given that the probe pairs with a specific DNA strand in the matrix, what can you conclude about the nucleotide sequence of the Baby’s DNA fragment that pairs with the probe sequence?
Answer:
The matrix can be used to detect the expression of the target gene
Explanation:
DNA probes enable to identify target acid nucleic sequences (i.e., DNA or RNA) that are capable of hybridizing with the probe. The probe is usually labeled with different 'detectors' (i.e., radioisotopes, fluorophores, epitopes, etc), thereby allowing its detection by observing the response to the hybridization process. For example, a DNA microarray can be used to detect simultaneously the expression of thousands target genes.
The conclusion related to the sequence of baby DNA fragment should be that the matrix is used for detect the expression of the target gene.
