What is the polypeptide chain produce by the template DNA strand
ACATGCGGTTAAATG? Please write the full name of each amino acid--no commas, no
abbreviations, no dashes.
Answer:
The correct answer is - cysteine Threonine Proline Isoleucine Stop
Explanation:
The polypeptide chain is formed by the two process protein synthesis which includes the first step of transcription and translation. Transcription is the process where the mRNA segment is produced by encoded from the particular DNA segment by complementary base seqences.
In the second process of translation, the amino acid is produced by the triplet codon present in the mRNA sequence with the help of tRNA and ribosome.
DNA : ACA TGC GGT TAA ATG
mRNA: UGU ACG CCA AUU UAG
Amino acid: UGU Cysteine
ACG Threonine
CCA Proline
AUU Isoleucine Stop
UAG Stop

How have the factors that trigger an asthma attack changed since the 1900s? As a researcher, how would you put together the clues given here to explain the emerging epidemic?
so if you look up things that can cause an asthma attack it will also show that viruses and bacteria are a cause. with asthma you lungs could already be inflamed as well as your air way wich makes it harder to breath. when you have c-19 it will inflame your lungs even more so it makes it even harder to breath given an asthma attack. more asthma attack now are probably caused by c-19 because it is all over the place and the percent of asthma attack by virus has dramatically increased.

Make a claim about why organisms need nitrogen. Support your claim with evidence, and explain your reasoning. Hint: Organisms use nitrogen to make __________.
Answer:
See the answer below
Explanation:
Living organisms need nitrogen to make important biomolecules that are necessary for growth and life functions. Nitrogen is a major component of proteins, amino and nucleic acids (both DNA and RNA).
Proteins and amino acids are required for the growth and overall health of living organisms while the nucleic acids are major components of hereditary materials which are important for cell division, growth, and repair.

List one abiotic and one biotic factor that humans use to limit pest population.
Answer: temperature, animal
Explanation:
Abiotic factor is a non-living environmental factor like soil, water, temperature, humidity, sunlight, and others. Biotic factor is a living factor including living beings like microbes, humans, insects, and others. A limiting factor is the one which can reduce the abundance and growth of living organisms. A limiting factor can be abiotic or biotic.
Temperature is one of the abiotic factors which can reduce the abundance of pests. Increase in temperature can kill pests, which cannot tolerate the rise in temperature. Animal that feed on pests can also reduce the abundance or population of the pests. Like lizards, frogs, and others.
what is mineral ?what are its type
Answer:
In geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid chemical compound with a fairly well-defined chemical composition and a specific crystal structure that occurs naturally in pure form
Explanation:
Silicate Minerals. The first classification of minerals is silicate minerals.
Native Element Minerals. Native elements refer to minerals that only contain the atoms of one type of element.
Carbonate Minerals.
Halide Minerals.
Oxide Minerals.
Mineral nutrients for the human body include: iron, calcium, copper, sulfur, phosphorus, magnesium and many others. An archaic use of the word "mineral" comes from the Linnaean taxonomy in which all things can be assigned to the animal, vegetable, and mineral kingdoms.
Warm air moves upward, while cold air moves downward. Which of the following best explains this pattern of heat transfer?
A
Differences in density caused by temperature differences create buoyant forces.
B
Gravity pulls cold air downward more strongly than warm air.
C
High-energy particles bounce upward off the ground in large numbers, causing convection.
D
Gravity acts on particles but not on energy, so thermal radiation rises.
Answer:
A) Density
Explanation:
cold air is more compact than warm air since particles aren't as active, therefore it is more dense and heavier than warm air.

what are the two physical processes that cause climate to change
Answer:Variations in the sun's energy - sunspot activity raises global temperature.
Volcanic eruptions , large quantities of volcanic dust in the atmosphere shields the Earth from incoming heat, (exposure to the Sun's rays), lowering global temperature.
Explanation:Increased heat, drought and insect outbreaks, all linked to climate change, have increased wildfires. Declining water supplies, reduced agricultural yields, health impacts in cities due to heat, and flooding and erosion in coastal areas are additional concerns.
