Answer:
time; point
Explanation:
The complete question is as follows:
The shortest length of time required to kill all test microbes at a specified temperature is the thermal death __________ whereas the lowest temperature required to kill all microbes in a sample within 10 minutes is the thermal death _________.
time; point
window; point
point; time
time; temperature
- When a population of bacteria gets killed due to exposure to high temperatures then this is termed as thermal death.
- The time taken to kill a specific microbe at a specific temperature is termed as the thermal death time. The length of the time taken depends on the nature of the target microbe and hence, varies from one to another.
- The lowest temperature that will kill all the microbes in a sample within ten minutes is defined as the thermal death point. The temperature at which the microbes get killed within 10 minutes also varies from one microbe to another.
- Thermal death results in the disruption of the cell membranes of the microbes and hence can kill the microbes.
Answer:
A biotic factor is a living organism that shapes its environment. In a freshwater ecosystem, examples might include aquatic plants, fish, amphibians, and algae. Biotic and abiotic factors work together to create a unique ecosystem.
Ribonucleic acid (rna) and additional deoxyribonucleic acid (dna) surrounds genes. in a process called methylation, they enhance, silence, or alter genetic instructions.
<h3>What is DNA methylation?</h3>
- Adding methyl groups to the DNA molecule is a biological process known as DNA methylation. Methylation has the ability to change a DNA region's activity without changing the sequence.
- When DNA methylation takes place at a gene promoter, it frequently decreases gene transcription.
- DNA methylation plays an important role in a number of critical processes in mammals, including aging, cancer, X-chromosome inactivation, genomic imprinting, and transposable element repression.
- The majority of eukaryotic genomes contain DNA methylation, a dynamic epigenetic alteration. It is well recognized to cause a high rate of CpG to TpG mutations.
- However, nothing is known about the connection between the rate of germline mutation and the dynamics of methylation during germline development.

<em>Answer:</em>
<em>modulate abiotic forces that, in turn, affect resource use by other organisms. both negative and positive effects on species richness and abundances at small scales, but things that a tree does than directly use the tree for ... changes in biotic or abiotic materials. in comparison to some of the other examples we discuss.</em>
