write a description of the ecosystem including biotic and abiotic factors? plz
Answer:
The correct answer is - Biotic factors are any living factors and abiotic factors are anything non-living in an ecosystem.
Explanation:
An ecosystem consists of all living organisms, non-living organisms that are present in a physical environment in a particular geographical area. The physical environment consists of several factors such as landscape, pH, climate, salinity, and other factors that represent abiotic factors.
Any living organism present in an ecosystem is biotic factor Examples of biotic factors include are mammals, birds, trees, microbes, grasses, fish, bacteria, and many more.

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.
What is one use of hydrogen?
Answer:
early all of the hydrogen consumed in the United States is used by industry for refining petroleum, treating metals, producing fertilizer, and processing foods. U.S. petroleum refineries use hydrogen to lower the sulfur content of fuels.
Explanation:
Answer:
However, hydrogen is useful as an energy source/fuel because it has a high energy content per unit of weight, which is why it is used as a rocket fuel and in fuel cells to produce electricity on some spacecraft. Hydrogen is not widely used as a fuel now, but it has the potential for greater use in the future. So there you have it!

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.

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

synthesis of protein with the help of ribosomes is
Answer:
Translation, or making a protein from an mRNA sequence, occurs on ribosomes. The amino acids are brought to the ribosome by transfer RNAs (tRNAs). The tRNA pairs up with the mRNA by matching up complementary nucleotides. This ensures that the correct amino acid is added to the protein.

ANSWER BOTH QUESTIONS about BIOLOGY PLEAASE!!
Answer:
Both are 1/A
Explanation:
Dominate traits will always show up because they over power the recessive trait, the only way a recessive trait would show would be if it was hom0zygous recessive (hh), otherwise the dominate trait would show (HH/Hh)
