Answer:

Similarities include: Both are involved in transporting big molecules across the membrane. ... formed from the cell membrane which then gets into the cytoplasm. Exocytosis increases the size of the cell membrane while endo does the opposite.

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.

Answer:

Protection

Explanation:

The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell. And that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.

Answer:

A

Explanation:

Different versions of genes

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.

Answer:

translocation, additions, transformation, and removal.

Explanation:

Soil horizons are the result of these four things.

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.

Explanation:

Answer: The process is called EUTROPHICATION. The correct option is C.

Explanation:

Eutrophication is a type of environmental pollution where by there is an increase in nutrient salts of a water body which can lead to structural changes in the affected aquatic ecosystem. These changes includes:

--> Increase in production of algae: this effect causes algae blooms which makes the water murky, greenish and unpleasant for certain activities such as swimming.

--> Decrease in aquatic life: the presence of excessive growth of algae which are often degraded by microorganisms. When the rate of degradation of the algae by microorganisms is greater than that of oxygen regeneration a hypoxic state occurs which is harmful to aquatic life example fishes.

Answer:

Sperms are the male gametes produced in the seminiferous tubules of the testes. The main difference between spermatogenesis and spermiogenesis is that spermatogenesis is the formation of sperm cells whereas spermiogenesis is the maturation of the spermatids into sperm cells.

Answer:

 d. Lysine is replaced by tryptophan (nonpolar)

Explanation:

Amino acid substitutions can have varying affects on the protein function, depending on the specific substitution and the location of the substitution.

If the substitution occurs in an important region, for example an enzyme active site, then the function of the protein could be destroyed.

Additionally, if the substitution replaces the amino acid with a highly different amino acid with different properties (eg. polarity), it could alter the structure and function of the protein.

Replacing lysine (polar) with a tryptophan (non-polar) changes the properties of the amino acid at that location, whereas the other substitutions do not.

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: I thinks it’s true.

Explanation:

Answer:

True.

Explanation:

it's D but I might be wrong

Answer:

C

Explanation:

In science, a hypothesis is an idea or explanation that you then test through study and experimentation. Outside science, a theory or guess can also be called a hypothesis.

Many scientists start with this as a need you make a prediction and base it around your experiment to prove your correct.

A) WHAT IS THE PROBLEM WITH HER PLAN?

Binary fission is one of the asexual process by which most bacteria reproduce, the binary fission brings about a doubling of the number in bacterial cells that are viable.

Generation time is that time that it will require for a cell population to divide and double, it is also known as doubling time. This Generation time varies among distinct organisms and also varies among culture conditions.

Take for instance,a fast growing bacterium that is under an ideal culture conditions has a doubling time of 20minutes and for the bacteria that is grown in a condition that is not so ideal,may have a doubling time of hours.

The major challenge/ problem with her plan is that as she takes the bacterial sample every 30minutes, and then hold the sample till the last sampling is done in the day,those bacterial cells that are collected in the initial intervals will then get divided and further gives a result that is false.

However,if those bacteria that are collected aren't stored in a culture environment that is standard,the bacterial cells may die off and thus will further bring about a false result.

2) CAN SHE DO ANYTHING TO IMPROVE THE ACCURACY OF HER RESULT?

Solution for rectifying the error in her plan;

She can go ahead and add 50-100 μl of formaldehyde to all the culture suspensions that she has and has taken every 30minutes.

As the formaldehyde will fix the bacterial cells,The optical density present in all those aliquots can then be retrieved/taken at the end of the day.

Looking at it alternatively, aliquot 1ml of the culture suspension at an interval of every 30 minutes,and then take the optical density that is OD at a wavelength of 600nm making use of spectrophotometer until the reason you get becomes static.

Answer:

5. Each three nucleotides in the gene template DNA codes for a three nucleotide codon in mRNA.

2. Each codon in mRNA codes for a specific amino acid.

1. The codon sequence in mRNA determines the amino acid sequence in a polypeptide.

3. The sequence of amino acids in a polypeptide determines how the protein will fold and possibly bind with other polypeptides to form a mature protein.

4. The final structure of a protein determines its function.

Explanation:

The process of gene expression follows the central dogma of biology I.e. Gene (DNA) --> mRNA ---> Protein. The process of gene forming mRNA is called transcription while the process of mRNA forming protein is called translation.

Based on this, the order of the flow of information from the DNA sequence to a functional protein is:

- Each three nucleotides in the gene template DNA codes for a three nucleotide codon in mRNA (transcription).

- Each codon in mRNA codes for a specific amino acid.

- The codon sequence in mRNA determines the amino acid sequence in a polypeptide (translation).

- The sequence of amino acids in a polypeptide determines how the protein will fold and possibly bind with other polypeptides to form a mature protein.

- The final structure of a proteiin determines its function.

The order is 'three nucleotides in DNA codes for a codon', 'each codon codes an amino acid', 'codon sequence determine amino acid sequence', 'amino acids determine protein folding' and 'final protein structure determines its function'.

During gene transcription, a fragment of DNA referred to as 'gene' is used as a template to create an mRNA, which is then used to synthesize a polypeptide.

The triplets of nucleotides or 'codons' in the mRNA sequence determine the amino acid sequence in the nascent polypeptide chain.

The synthesized protein is then folded in the endoplasmic reticulum (ER) and thus adopts its three-dimensional (3D) conformation.

Protein folding is achieved by specific proteins called chaperones that help to correctly fold the protein, which adopts a mature conformational active state.

In conclusion, the order is 'three nucleotides in DNA codes for a codon', 'each codon codes an amino acid', 'codon sequence determine amino acid sequence', 'amino acids determine protein folding' and 'final protein structure determines its function' (order 52134).
