Which number indicates the number of atoms of each element in a molecule of a substance.

LUCKY_DIMON [66]

I think the answer MIGHT be D. RNA synthesis is carried out by proteins known as RNA polymerases that transcribe the genetic information from DNA in a highly-regulated, multi-stage process. But transcribe and translate are different so I'm not a 100% sure. Hope this helps!

During a visit to a desert ecosystem, a student observes the

faust18 [17]

Answer: D) The lizard and the snake are secondary consumers.

Explanation:

Producers are organisms that, simply put, produce their own food. All photosynthesizing plants are considered to be producers. Animals cannot be producers.

Primary consumers eat producers.

Secondary consumers eat primary consumers.

Tertiary consumers eat secondary consumers, and so on.

The lizard eats a fly, which is a primary consumer. This makes the lizard a secondary consumer.

The snake eats a mouse, which is a primary consumer. This makes the snake a secondary consumer.

A) is incorrect because the hawk is a tertiary consumer.

B) is incorrect because grass is a producer, not a consumer

C) is incorrect because the lizard is a secondary consumer

Explain how the equations for photosynthesis and respiration are related. Identify each as being either catabolic or anabolic re

larisa [96]

Answer:

An anabolic reaction can be described as a reaction in which reactants join to form products. In the process of photosynthesis, carbon dioxide and water molecules join to build up glucose molecules hence, it is an anabolic reaction.

The catabolic reaction can be described as a reaction in which large molecules are broken down into smaller substances. In cellular respiration, glucose is broken down into carbon dioxide and water. Hence, cellular respiration is a catabolic reaction.

The equations of photosynthesis and cellular respiration are exactly opposite to one another. Hence, holding a connection. The products of photosynthesis are the reactants of cellular respiration and vice versa.

What would be the most likely effect on the transcription of the trp structural genes for the mutation scenarios provided? mutat

blagie [28]

Answer:

I've responded to each scenario individually, please see below:

1. mutation that prevents ribosome binding to the mRNA

No transcription occurs

2. 5' UTR mutation that changes region 1 tryptophan codons into alanine codons

Transcription when alanine is low

3. mutation that creates a stop codon in region 1 of mRNA 5' UTR

Transcription occurs, a truncated protein will be made during translation

4. deletions in region 2 of the mRNA 5' UTR

Transcription occurs, region 1 and 2 might get paired together

5. deletions in region 3 of the mRNA 5' UTR

Transcription occurs, region 3 and 4 could combine to form a hairpin loop structure

6. deletions in region 4 of the mRNA 5' UTR

Transcription occurs, region 3 and 4 could combine to form a hairpin loop structure

7. deletion of the string of adenine after region 4 of the mRNA 5' UTR

Transcription occurs, however, it will not be as stable a molecule because of losing its polyA tail

Hope that answers the question, have a great day!
