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.

Answer: nucleic acid in a virus is enclosed in a capsid.

Explanation: Capsids are made up of protein subunits called protomeres. some viruses have a membrane also known as an envelope that surrounds the capsid and some do not.

Answer:

Capsid

Explanation:

Capsid - The capsid is the protein shell that encloses the nucleic acid; with its enclosed nucleic acid, it is called the nucleocapsid. This shell is composed of protein organized in subunits known as capsomers.

Answer:

At the interior side.

Explanation:

Nonpolar amino acids of a protein more likely to be found at the interior side of the  soluble proteins where they are far from the water because water is a polar molecule and only polar amino acids of protein can interact with the water so that's why the polar amino acids are present on the surface of  soluble proteins and the nonpolar amino acids of a protein are present at the interior side of the soluble proteins due to its nonpolar nature.

The change results from the breakdown of starch into glucose by saliva 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.

Answer: Options A, B ,C and E are correct

Explanation:

The structure of pyruvate dehydrogenase complex comprises if three enzymes E1, E2 and E3 which convert pyruvate to acetyl CoA. The three enzymes are have several copies.

Within the PDH complex, the E2 subunit forms the structural unit, contain three domains and are surrounded by E1 and E3. The E 2 accepts acetyl groups from E1 and transmit the group to coenzyme A. The decarboxylation of pyruvate and its conversion to acetyl-CoA by the PDH complex comes first before glucose carbon enter into the tricarboxylic acid (TCA) cycle. This process is important to the aerobic oxidation of glucose .

Answer:

A. The bacteria are breaking down sugars in the absence of oxygen.

Explanation:

Bacteria are microscopic single-celled organims. These organisms may produce their own source of chemical energy, or consume and absorb chemical energy made by producers.

They break down chemical energy like glucose through lactic acid fermentation in their cytoplasm, without the presence of oxygen.

In Glycolysis:

2 molecules of ATP are used to break up glucose into 2 molecules of pyruvate, 4 ATP and 2 electron carrying NADH molecules. Since 2 ATP are used, a net 2ATP are produced by this process.

Then, pyruvate is converted to lactic acid, producing 2 NAD+, used as electron carriers.

The option that best describes the process by which bacteria break down glucose to produce lactic acid is when bacteria break down sugars in the absence of oxygen. The correct option would, thus, be A.

Bacteria are capable of breaking sugars to generate energy, a process known as respiration.

This respiration can either be in the presence (aerobic) or absence (anaerobic) of oxygen.

Aerobic respiration has 3 major steps:

Both the 2nd and 3rd steps in aerobic respiration require oxygen and the summary of the entire process is in the following equation:

[tex]C_6H_1_2O_6 + 6 O_2 ---------> 6 CO_2 + 6 H_2O + ATP[/tex]

In the absence of oxygen, only glycolysis occurs and the pyruvates generated are quickly converted to lactic acid to generate a small amount of ATP according to the following equation:

Pyruvic acid + NADH <---> lactic acid + NAD+

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

Answer:

First Image - Creep

Second Image - Mudflow

Third Image - Slump

Explanation:

In geology, creep in landform is known to be the movement of loose, weathered material which occurs on every slope slowly on a downslope. The downslope is caused by persistent tilting of gravestones, trees, etc.

Mudflow involves the very rapid flow of debris which are liquified as a result of the significant amount of water which then leads to mass wasting. This occurs when water mixes with soil and rock and makes the mud mass to flow rapidly.

While slump involves the falling out or removal of earth ir rock debris from the slope of unconsolidated material which moves downward intermittently.

Creep, Mudflow and Slump all lead to landforms.

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.
