An increase in the available water in an ecosystem would increase the sustainability of an ecosystem.

An increase of human interference can negatively impact local flora and fauna populations.

A decrease in the amount of sunlight would negative impact plants.

A decrease in the number of available producers will negatively impact the entire food chain/food web.

Answer:

An increase in the available water in an ecosystem.

Explanation:

An abiotic factor of an ecosystem is a non-living factor.

"A decrease in the number of available producers in the area. " Would be a biotic factor and would affect the environment for the worse. It would be the same with the second option too.

The third one is an abiotic factor but it would affect the environment for the worse.

The best answer would be the first option.

Hope this helps.

Answer:

1) B - protein channel

2) D - to assist in the movement of substances across the membrane by facilitated diffusion or active transport

Explanation:

1) B is the answer because the proteins would travel through the protein channel to enter or leave the cell.

2) D is the answer because the channel allows protein molecules to pass through a selectively permeable cell membrane through active transport and facilitated diffusion.

Hope this helps!

Answer:Airedale Terrier is a Dog specie,the Airedale Terrier is the largest of all terrier breeds.

(1) Respiration

(2) Nutrition

(3) Reproduction

(4) Movement

(5) Irritability

Explanation: A living specie is a specie that poses all the characteristics of a living organisms such MOVEMENT, REPRODUCTION, NUTRITION, IRRITABILITY,GROWTH, EXCRETION, REPRODUCTION AND DEATH.

Respiration is the process through which living organisms take in oxygen in order to break down food for the release of energy and carbon dioxide.

Nutrition is the process of feeding or intake of nutrients Airedale Terrier feeds on both plants and animals ( OMNIVORES).

Reproduction is the process through which the younger generation are brought to life Airedale Terrier reproduce through Sexual reproduction.

Movement is the change of location,Airedale Terrier moves from one point to another.

Airedale Terrier responds to different stimuli ranging from sound,light,touch, taste etc.

Use the numbers to put the steps of translation in order, from first (1) to last (5). The large ribosomal subunit completes the
pashok25 [27]
Translation is a complex process that translated the genetic information from the language of DNA in the language of RNA. The first step in this process is the binding of the initiator tRNA (that is bound to the aminoacid methionine) to the small ribosomal unit. Then, the small ribosomal unit joins the mRNA; it is the part of the ribosome mainly responsible for translating. After that, the initiator tRNA binds to the start codon. This reaction frees some initiation factors that make large ribosomal units bind to the small one. Hence, <span>the large ribosomal subunit completes the initiation complex afterwards. The role of the large ribosomal unit is mainly to make the peptidic bonds between the aminoacids in the new protein. After that, </span><span>amino acids are paired with anticodons, gradually forming a long chain</span>; this chain is called a polypeptide and is the skeleton of the protein that is created. Finally, this process stops when one of the three possible stop codons are reached.

Using this codon chart, can someone help me give my the mRNA,tRNA,and amino acids from the original DNA sequence “ACT TTC GAT”
nevsk [136]

Answer:

DNA:   ACT TTC GAT

mRNA: UGA AAG CUA

tRNA: ACU UUC GAU

AA: stop-lysine-leucine

Explanation:

mRNA is the complementary sequence of the DNA strand and tRNA is a complementary sequence of mRNA sequence. mRNA is a sequence of bases that is formed by encoding the DNA sequence in the complementary pattern during transcription.

tRNA is complementary of the mRNA code to produce the amino acid which is decided by the codon ( a three- base sequence of mRNA) what amino acid be present in what sequence.

Thus,

DNA:   ACT TTC GAT

mRNA: UGA AAG CUA

tRNA: ACU UUC GAU

AA: stop-lysine-leucine (however, after the stop codon amino acid chain terminated in any protein)
