An amino acid is synthesized by the prokaryote, E. coli. The genes for the enzymes are responsible for synthesizing this amino a

cid are encoded in an operon. The operon is regulated by a reperssor. When the amino acid binds to the repressor, the repressor changes shape so it can bind to the operator. Which of the following statements is true?
A. When levels of the amino acid are high, it binds to the repressor, allowing synthesis of this amino acid to proceed.
B. When levels of the amino acid are low, it binds to the repressor, allowing synthesis of this amino to proceed.

const2013 [10]

Answer:

The group needs to find signs of apical dominance, growth in response to light, vascular tissue differentiation, formation of lateral and adventitious roots, etc.

Explanation:

Lanolin is a solvent used to study physiological processes in plants by diluting hormone growth regulators (in this case, indole acetic acid). Indole acetic acid (IAA) is the most important auxin hormone in plants. Auxins are essential plant hormones synthesized in expanding shoot tips that move down the stem to the roots. These hormones coordinate cell division, elongation and identity during plant body development. IAA hormone is well known to regulate different plant developmental processes including, among others, apical dominance (where the central stem grows more strongly than other lateral stems), tissue differentiation, stem elongation, phototropism (growth in response to light) and gravitropism (response to gravity). For instance, under the application of IAA, it is expected that bean stems grow to imitate the response to light (phototropism) by bending away from the side where lanolin was applied.

One of the two major systems that are affected by the stress response is the ____________, which results in increased production
Marizza181 [45]
The two major systems involved in the stress response are the Nervous System [the Sympathetic subdivision of the Autonomic Nervous System (ANS)] and the Endocrine System (glands which secrete hormones intonthe bloodstream).
The Endocrine System's response during acute and/or chronic stress (adaptation) involves first the Hypothalamic release of Corticotropin-Releasing Hormone (CRH), which stimulates the Anterior Pituitary (via the blood) to release AdrenoCorticoTropic Hormone (ACTH), which then activates the Adrenal Cortex to release glucocorticoid hormones (i.e. Cortisol), amongst others into the bloodstream. Cortisol then has many effects on tissues and organs throughout the body to allow better generalized coping with the initial stress stimulus.

Scientist have been measuring increasing levels of greenhouse gases in Earth's atmosphere. How do increasing levels affect the a
rjkz [21]

Well, we have a book to write on this topic but imma explain it briefly plus simply.

  • Global warming emphasizes the environment with rising temperatures, water shortages, increased fire threats, droughts, weeds and pest attacks, severe storm damage and salt attacks, to name just a few.(In simple words)

Now, we'd go briefly and discuss some common affects briefly :

  1. Hotter days - The climate is getting more and more warmer and year 2015 was the hottest year ever record throughout the history. The Earth's temperature had already warmed by 1°C which is really dangerous.
  2. Rising sea levels - Rising sea levels due to climate change is the biggest problem causing natural calamities. Increased ocean temperatures are melting glaciers and ice caps all over the world. Melted ice increases the volume of water in our oceans. Warmer temperatures also result in the expansion of the water's mass, which causes sea levels to rise, threatening islands and coastal cities.
  3. More frequent and intense extreme weather - Extreme weather events like bushfires, cyclones, droughts and floods are becoming more common and more aggressive as a result of global warming.

notka56 [123]

Answer:

The percentage of people in Botswana that have HIV is 24. 83 percent .

Explanation:

Lesotho and Swaziland are the only country who is higher than Botswana in terms of terms of HIV prevalence rate in the world between adults aged from 15 to 49 years .

This condition has led to a major depletion in Botswana's workforce, because a good number of productive adults (18 to 50) developed AIDS and are unable to work .
