Answer:
Yes. they are living and living in the backyard so therefore they are considered part of the population of the backyard. You can also include any birds, squirrels, and any other animals that you see.
Hope This Helps!
Answer:
The mass of a star determines its life cycle, that is, more the mass, shorter will be its life cycle. The mass of the star is determined by the concentration of matter, which is found within its nebula. In the nebula, with time, the hydrogen gas comes in close proximity with each other due to gravity and starts to spin.
With the brisk spinning, the gas heats up and turns into a protostar. The temperature now reaches 15,000,000 degrees and within the core of the cloud, the phenomenon of nuclear fusion takes place. The cloud now contracts a little, starts to glow brightly, and turns stable. The cloud now becomes a prime sequence star, and will stay in this phase for millions of years, the Sun of our galaxy is in this stage at the moment.
Answer:
She might study the function of putative oncogenes and/or tumor suppressor genes in AML mice by transfecting small interfering RNAs (siRNAs) which are able to suppress the expression of genes of interest through the RNA interference (RNAi) pathway
Explanations:
The RNA interference (RNAi) pathway is a naturally occurring mechanism which is used in molecular biology laboratories to inhibit the expression of target genes. The RNAi technique consists of delivering small interfering double-stranded RNAs (siRNAs, 18-30 nucleotides in length) into the cells in order to inhibit the translation of genes and/or trigger mRNA degradation, thereby suppressing target gene expression. These siRNAs are specifically designed to bind by complementarity to transcripts of target genes (i.e., mRNAs). In this case, the RNAi pathway can be used to study the function of genes involved in AML pathways (e.g., apoptosis, cell proliferation, etc).
2) Heat
Only heat can be transferred from one object to another object by the means of conduction , convection and radiation .Even if the energy is being transferred by kinetic energy that is also in the form of heat .This can simply be understood by taking the example of two balls say one ball is stationary and other one is moving ,the particles inside the moving ball is having high kinetic energy as compared to that of stationary and when the both the balls colloid the energy is transferred in the form of heat and the other ball which was at stationary starts moving .
So,ultimately heat is transferred between objects.
