Asthma is a chronic disease of the lung that has been increasing at an alarming rate in industrialized countries around the world over the last few decades. Although considerable progress has been made in our understanding of the underlying pathogenesis of the disease, the exact causes of the increasing prevalence are unknown. Studies suggest that most asthma develops in early childhood and that environmental factors present early in life may be crucial in the development of disease. One potential explanation for the recent epidemic referred to as the "hygiene hypothesis" postulates that factors that have resulted in a reduction in exposure to microbial products and/or infections in the western world may be contributing to this rise in disease prevalence. As early life influences are known to play an important role in establishment of asthma, studies have focused on the interface between mother and child that occurs during gestation and through breastfeeding. In this regard, the body of evidence regarding the relationship between breastfeeding and asthma indicates benefit but with the potential for risk. While providing population-level protection from infections and atopy in infancy and early childhood, breastfeeding might also pose an increased risk of atopic asthma among children with asthmatic mothers.

Of the answers below, what is the smallest nucleotide sequence that could code for a protein with 300 amino acids?
ololo11 [35]
The nucleotide sequence would have to have 900 nucleotides in order to code for a protein of 300 amino acids. When translating RNA into proteins, RNA is read 3 bases at a time. Each group of 3 bases is a codon, and each codon codes for an amino acid. When read, the proper amino acid is added to a growing chain of amino acids, which will be folded to become a protein.

Therefore, 300 amino acids * 3 nucleotides per amino acid = 900 nucleotides.

andrey2020 [161]

Answer:

Skeletal muscles fibre are classified base on how the produce energy.

Explanation:

Skeletal muscles fibres consist of bundles of cells that form muscles which contain myobrills.

Skeletal muscles are classified based on how the produce energy;

Type 1 or slow pitch muscle fibres are more efficient and last for a long period of time. They are use for postural maintenance or endurance. It use aerobic respiration to produce energy or ATP.

Type 11 or fast twitch muscle fibres use anaerobic respiration and are for short speed and fatigue more easily than type 1.

Which of the following is typically associated with a reduction in photosynthesizing plants in a water supply? (2 points)
Sphinxa [80]
A decrease in dissolved oxygen.
This is because oxygen is a byproduct of photosynthesis. If the plants are in water, some of the oxygen they produce will become dissolved in it. Without those plants, you have less dissolved oxygen.
