Describe how positive control in prokaryotes can be altered by the external environment
Answer:
The positive control is control when there is an activator present which acts as a regulatory protein so the operon and activator binds and initiates the stimulation of transcription to express the gene. In absence of this activator or regulatory protein, the operon will be inactivated.
External environmental stimuli can lead to alteration of the positive control in prokaryotes such as excess lactose in the environment. These environmental stimuli can induce transcription in prokaryotes.
In this example, if glucose is not available in the environment, the transcription of the lac operon will be induced by the presence of lactose in the environment.

What role do chromosomes play in genetic inheritance
Answer:
Each gene occupies a specific position on a chromosome. Because genes provide instructions for making proteins, and proteins determine the structure and function of each cell in the body, it follows that genes are responsible for all the characteristics you inherit. ... These pair up to make a total of 46 chromosomes.
Calculate the mass of 2.8 moles of chlorous acid (HCIO). Explain the process or show your work by including all values used to determine the
answer.
Answer:
147g
Explanation:
The number of moles or mass a substance contains can be calculated using the formula:
Mole (mol) = Mass (g) /Molar mass (g/mol)
Based on the provided information in this question,
mole = 2.8moles, mass =?
Molar Mass of HClO
Where; H =1, Cl=35.5, O=16
1 + 35.5 + 16
= 52.5g/mol
Using mole= mass/MM
mass = mole × MM
mass = 2.8 × 52.5
mass = 147g
147g of chlorous acid (HClO)
Do all living things obtain the matter and energy they need to live and grow in the same way?
Answer:
Explanation:
This means all living organisms must obtain and use energy to live. Energy is the power to do things. ... A living organism can either make its food or depend on others to make food for them. For example, green plants produce their food from a process called photosynthesis.
Living things obtain energy and food to grow but different organisms do in different ways plants depend on the sun for photosynthesis.
How do living things obtain energy?Every living thing has a unique method of getting nutrients. Protozoans and other animals are among the creatures that obtain nutrition by eating food. Through the process of photosynthesis, plants and algae produce their own sustenance.
Animals consume food and drink to get the substance and energy they require for their biological activities.
A producer is an organism that produces its own nourishment. Sugars, a source of both energy and substance, are produced by plants using the energy from sunshine.
Therefore Plants are one type of creature that can produce its own food, to obtain energy.

What kind of change results from the breakdown of starch into glucose by saliva? Physical or chemical ?
Answer:
Yes im doing the science final
The change results from the breakdown of starch into glucose by saliva is chemical change.
What is chemical change?When bonds between molecules or atoms are created, disrupted, or both, chemical changes result.
In other words, a substance with one set of qualities gets changed into another substance with a different set of attributes.
Chemical decomposition is the term used to describe the subsequent chemical change as more products are produced as a result of this process.
When two materials interact to form a new substance, chemical synthesis—or, conversely, chemical breakdown into two or more independent molecules—occurs.
The starch gradually transforms into sugar when saliva is supplied because saliva contains the enzyme amylase, which helps break down starch.
Starch is a polysaccharide made up of many units of glucose. Amylase breaks down starch to produce a disaccharide called maltose.
Thus, the given one is the example of chemical change.

Explain why the ratio of motor neurons to muscle fibers is greater in muscles that control eye movement than in postural muscles of the leg.
Answer:
The muscles of the eye cover a greater number and in turn carry out greater fine motor skills.
Explanation:
Alpha motor neurons are neurons that invent the skeletal muscle, that is, striated, so that through the motor plate that is the unit that unites them, an action potential is transmitted that contracts the sarcomeros of the elastic fibers and the z lines. come closer, each eye movement is much more precise than the locomotion of the lower limb, which carries greater innervation in each muscle bundle due to the specificity of the movement, this is how more alpha motor neurons are required to mobilize the eye than a leg.
The specificity and preciseness of eye movement control justifies why the ratio of motor neurons to muscle fibers is greater for muscles controlling eye movement than those in the postural muscles of our leg.
The function the eyes performs requires more precise locomotion control than the movement of the limbs require.
For an eye movement to be made, an action potential must be transmitted which makes the sarcomeres of the elastic fibers and z-lines to unit thereby producing movement of the eye. This movement are usually done with almost perfect preciseness.
This is why there are more alpha motor neurons that control eye movement than we have in postural muscles of the leg.
In summary, the specificity and preciseness of eye movement control justifies why the ratio of motor neurons to muscle fibers is greater for muscles controlling eye movement than those in the postural muscles of our leg.
