Answer:
Many important components of animal behavior, growth, and reproduction are tightly linked to environmental conditions, particularly for ectothermic freshwater organisms. For amphibian species, factors such as temperature and rainfall can be physiologically limiting and alter activity levels. The effects of environmental conditions on terrestrial amphibian movement have been well characterized, but less is known about the importance of these factors in aquatic habitats. Here we investigate the impact of temperature and rainfall on the activity of a pond-dwelling amphibian using capture patterns of aquatic adult red-spotted newts (Notophthalmus viridescens). Data on newt captures, air temperature, and rainfall were collected for 6 years (2009, 2011, 2013–2016) during the winter breeding season at a wetland in the Piedmont region of North Carolina, USA. In 2016, we collected more detailed data on the size and sex of captured newts, as well as recording water temperature.

Cells are divided into two main classes, initially defined by whether they contain a nucleus. Prokaryotic cells (bacteria) lack a nuclear envelope; eukaryotic cells have a nucleus in which the genetic material is separated from the cytoplasm. Prokaryotic cells are generally smaller and simpler than eukaryotic cells; in addition to the absence of a nucleus, their genomes are less complex and they do not contain cytoplasmic organelles or a cytoskeleton (Table 1.1). In spite of these differences, the same basic molecular mechanisms govern the lives of both prokaryotes and eukaryotes, indicating that all present-day cells are descended from a single primordial ancestor.

Answer:
ATP production
Explanation:
When the lion eats the buffalo, the eaten material is broken down to give ATP (Adenosine Triphosphate), which in turn helps the body in its metabolic processes like the synthesis of carbohydrates and proteins, which act as a building block for the lion.
Answer:
Because the promoter region is initiation sites for transcription to occur.
Explanation:
Transcription is the first process of gene expression in both eukaryotic and prokaryotic cells. Transcription involves the synthesis of a complementary RNA strand from a DNA template. It is carried out by an enzyme called RNA polymerase which binds to the DNA molecule and adds nucleotides based on the sequence it reads on the DNA.
On the DNA molecule, are sequences of nucleotides which the RNA polymerase recognizes and binds to in order for the transcriptional process to start. These sequences are called PROMOTER regions. They are located upstream i.e. after initiation site, of the DNA. Without these promoter region, RNA polymerase cannot bind to the DNA molecule and hence transcription cannot occur.
