Answer: Unlike leading strands, lagging strands are synthesized as discrete short DNA fragments, termed 'Okazaki fragments' which are later joined to form continuous duplex DNA. Synthesis of an Okazaki fragment begins with a primer RNA-DNA made by polymerase (Pol) α-primase.

Answer:

Infections are generated by pathogens, pathogens that generate a rare invasion triggering an extremely risky condition for the host, opportunistic infections are usually caused by highly pathogenic microorganisms with high resistance mechanisms and are really serious signs and symptoms.

Primary pathogen is one that colonizes in a primary way by forming a biofilm or a microbiological ecosystem.

The great difference between infection and infectious disease is that the infection is the presence of microorganisms that cooperate and live with the host without generating pathology, whereas infectious disease is when these microorganisms generate a pathology or condition in the host.

Explanation:

The pathogenesis are different stages that make up the ability of a microorganism to get sick, an example is prevotella parvula or treponema denticola that during pathogenesis they quickly invade the tissues due to their movements, in addition to the tissues such as the mucosa they generate an immune distraction that release toxins in different areas to the invasion.

These are pathogenicity mechanisms, that is, how the microorganism does to be able to invade the tissues in the most oppressive way.

This question is incomplete

Explanation:

This question is incomplete. However, it should be noted that the idea of blocking the drainage, which could cause waterlogging (since the water will not be able to leave the field), is a type of irrigation that ensures there is sufficient amount of water for the plants to grow during a growing season. Although, some plants do not grow well in environments like this (in the case of waterlogging) because this environment lowers oxygen level in the root o the plant (caused by the water at the top of the soil).

Answer:

Once the myosin-binding sites are exposed, and if sufficient ATP is present, myosin binds to actin to begin cross-bridge cycling. Then the sarcomere shortens and the muscle contracts. In the absence of calcium, this binding does not occur, so the presence of free calcium is an important regulator of muscle contraction.

Answer:

10 chromosomes

20 chromatids

Explanation:

Meiosis is the process by which sexually reproducing organisms produce gametes for sexual reproduction. Meiosis, which reduces the chromosomal number of the parent cell by half, occurs in two stages namely: meiosis I and meiosis II.

Meiosis I is where the actual reduction in chromosomal number takes place because homologous chromosomes are separated in this stage. For example, a cell in G1 that has 20 chromosomes will have 10 chromosomes in each daughter cell at the end of meiosis I.

Since, DNA replication occurs in the S-phase, sister chromatids are formed for each chromosome. Hence, there would be 20 sister chromatids joined together by a centromere at the end of meiosis I.

The most likely to be an energy source for the cells of a living thing is a disaccharide (Option C).

A disaccharide is a carbohydrate composed of two monosaccharide units.

Cellular respiration refers to a series of metabolic reactions by which cells produce ATP, the energy coin of the cell.

Monosaccharides (e.g., glucose) represent the main source of energy used by cells during cellular respiration.

In conclusion, the most likely to be an energy source for the cells of a living thing is a disaccharide (Option C).

Answer:

Explanation:

hope this helps a little

Answer:

Explanation:

From the given information,

The first process is to determine the initial growth rate by using the formula:

[tex]R_o = \dfrac{In(2)}{t_d}[/tex]

where;

The initial growth rate(constant) = [tex]R_o[/tex] ; &

the doubling time = [tex]t_d[/tex] = 1 year

[tex]R_o = \dfrac{In(2)}{1 \ year}[/tex]

[tex]R_o[/tex] = 0.693 / year

Now, we move up to the net stage to find the growth constant by using the formula:

[tex]r = \dfrac{R_o}{(1 - \dfrac{N_o}{K})}[/tex]

where;

[tex]N_o[/tex] = population of fish in the pond = 100

[tex]R_o[/tex]  = The initial growth rate(constant)  = 0.693 /year

K = carrying capacity = 2000

Then;

[tex]r = \dfrac{0.693 \ /year }{(1 - \dfrac{100}{2000})}[/tex]

[tex]r = \dfrac{0.693 \ /year }{(1 - 0.05)}[/tex]

[tex]r = \dfrac{0.693 \ /year }{(0.95)}[/tex]

r = 0.730 / year

a)

Now, the maximum yield can be evaluated by using the expression:

[tex]= \dfrac{rk}{4}[/tex]

[tex]= \dfrac{0.730 \times 2000}{4}[/tex]

= 365 fish per year

Also, the maximum sustainable yield is said to be half of the carrying capacity suppose that the population growth obeys logistic curve;

i.e.

[tex]N' = \dfrac{1}{2} \times 2000[/tex]

N' = 1000 fish

b)

If the population is maintained at 1500 fish;

The sustainable yield can be calculated by using the formula:

The Sustainable yield = [tex]r\times N (1 - \dfrac{N}{K})[/tex]

The Sustainable yield = [tex](0.730/ year ) (1500) (1 - \dfrac{1500}{2000})[/tex]

The Sustainable yield = 1095 × 0.25

The Sustainable yield = 273.75 fish per year

The Sustainable yield ≅ 274 fish per year

Population size should be maintained to achieve maximum yield and Sustainable yield if population is maintained at 1,500 fish are 364.7 , 273.525 fish per year

Given that;

Stock in start = 100 fish

Double in 1 year

Capacity of pond = 2000 fish

Find:

Population size should be maintained to achieve maximum yield

Sustainable yield if population is maintained at 1,500 fish

Computation:

Growth rate = ln₂ / 1

Growth rate = 0.693 per year

With no growth constraint r = [tex]\frac{0.693}{1-\frac{100}{2000} }[/tex]

With no growth constraint r = 0.7294 per year

A. Population size should be maintained to achieve maximum yield = [tex]\frac{0.7294 \times 2000}{4}[/tex]

Population size should be maintained to achieve maximum yield = 364.7 fish per year

B. Sustainable yield if population is maintained at 1,500 fish = [tex][(0.7294))(1500)][1-\frac{1500}{2000} ][/tex]

Sustainable yield if population is maintained at 1,500 fish = 273.525 fish per year

Answer:

The correct answer is option A. binding of a new molecule of ATP.

Explanation:

Actin and myosin are complementary filaments present in muscle, actin is thin and myosin is a thick filament, these two filaments are responsible for the movement by muscle contraction and relaxation. Actin and myosin head shows great affinity towards one another.

Myosin heads are tightly attached to neighboring actin thin filaments due to its affinity to actin, however, myosin at other pockets also show a huge affinity for ATP. If myosin is bound to actin the affinity for ATP is changed and if new ATP bounds to the empty pockets it changes the conformation of myosin and prevents lockup or binding of the actin-myosin protein.
