Analyze the example of gene expression of the bacteria below:

In this example, what would cause the genes to be expressed?

An operon that is turned off
Polymerase being blocked from bonding to the DNA
The presence of an active repressor
A repressor that is unable to bond to the DNA

Answers

Answer:

This question is incomplete as it lacks the image. The answer is:

D. A repressor that is unable to bond to the DNA

Explanation:

The expression of a gene in a prokaryote like bacteria is regulated at the transcription level. Normally, a Gene is expressed by first undergoing transcription from DNA to mRNA with the aid of an enzyme called RNA polymerase.

However, a protein called REGULATORY PROTEIN which serves as a repressor inhibits the binding of RNA polymerase to the DNA sequence. According to this question, the gene will only be expressed if the repressor is unable to bond to the DNA, hence, not being able to prevent transcription.

Answer:

Weathering.

Explanation:

Weathering is the breaking down of rocks, soils, and minerals as well as wood and artificial materials through contact with the Earth's atmosphere, water, and biological organisms.

The process when rocks break into smaller pieces due to exposure to natural elements is called weathering.

What is weathering?

Weathering can occur through physical, chemical, or biological means.

Physical weathering involves the mechanical breakdown of rocks into smaller fragments without changing their chemical composition. Chemical weathering, on the other hand, involves the breakdown of rocks through chemical reactions, resulting in the formation of new minerals. Biological weathering is caused by living organisms, such as plants and animals, that can physically break down rocks or release chemicals that can alter the rocks' composition.

2. Consider a well-trained 130-pound female marathon runner, Jordan. Jordan has just loaded up on a carbohydrate meal and has the maximum amount of stored glycogen (6.8 grams of glycogen per pound of body weight). (10pts) a. How many grams of glycogen is Jordan storing in her body? Show your calculations

Answers

Answer:

884 grams of glycogen

Explanation:

Jordan's body weight = 130 pounds

Rate of storage of glycogen per pound of bodyweight = 6.8 grams

Total grams of glycogen that Jordan can store at maximum capacity:

  bodyweight x rate of storage

      = 130  x 6.8 grams

           = 884 grams

Hence, Jordan is storing 884 grams of glycogen in her body.

Discuss the mechanisms of speciation

Answers

Answer:

There are four major variants of speciation: allopatric, peripatric, parapatric, and sympatric. Speciation is how a new kind of plant or animal species is created. Speciation occurs when a group within a species separates from other members of its species and develops its own unique characteristics.

The key to one species diverging into two or more different species is establishing a barrier to gene flow. ... In this way, geographic isolation may lead to reproductive isolation and the formation of new species. Allopatric speciation is thought to be the main mechanism of speciation among most groups of organisms.

A. Decreased respiration
B. Decreased heart rate
C. Increased blood flow to digestive tract
D. Decreased saliva production

Answers

Answer:

D

Explanation:

D, or decreased saliva production is not a reaction of the parasympathetic nervous system (PSNS) since the PSNS actually increases/causes salivation which helps you digest your food.

As a tip, I usually associate the PSNS with a state of rest/restful conditions, as opposed to the sympathetic nervous system which is the opposite and is associated with stress and high-pressure conditions (like fight or flight).
