This modification allows the drug to prevent viral DNA synthesis by different mechanisms as an enzyme DNA polymerase follows.
What do you mean by DNA synthesis?DNA synthesis may be defined as the biological process by which a deoxyribonucleic acid (DNA) molecule is created.
The enzyme DNA polymerase adds some of the nucleotide bases to the strand that contains 3'-OH at the end. But when the end part of the strand lacks the 3' OH group, it inhibits the process of DNA transcription.
Therefore, this modification allows the drug to prevent viral DNA synthesis by different mechanisms as an enzyme DNA polymerase follows.

From his observations in the oceanic islands like the Galapagos, Darwin felt that: isolation is a significant factor in adaptation and speciation spontaneous generation is a significant factor in adaptation and speciation volcanic soils are a significatnt factor in adaptation and speciation inheritance of acquired characteristics is a significant factor in adaptation and speciation. none of these is correct
Answer:
isolation is a significant factor in adaptation and speciation
Explanation:
In the theory of evolution by natural selection proposed by Darwin, adaptation refers to the adjustment of organisms to their environments in order to increase their chances of survival in that environment. In the Galapagos Islands, Darwin observed that finches had different types of beaks adapted to the type of food they ate. From this observation, Darwin proposed that finches evolved to eat different food sources. In this case, the islands lead to an adjustment (evolutionary) process by which geographically isolated individuals accumulate genetic differences in order to adapt them to the environmental conditions in the islands, which then may also prevent breeding between individuals from different islands when they are reunited (i.e., it may also lead to speciation).

Which of these describes a nebula
Answer:
A nebula is a giant cloud of dust and gas in space. Some nebulae (more than one nebula) come from the gas and dust thrown out by the explosion of a dying star, such as a supernova. Other nebulae are regions where new stars are beginning to form. For this reason, some nebulae are called "star nurseries."
Explanation:
the development of lateral roots is intiated by the the cork or periderm
Answer:
Because lateral roots are initiated in the pericycle and grow out through the cortex and epidermis, they are said to have an internal, or endogenous, origin, in contrast to the external, or exogenous, origin of leaves and the apical meristem of stems (see below Stems).

4. A bacterium is discovered with new mutated form of isocitrate dehydrogenase that catalyzes the same reaction but produces hydrogen gas instead of NADH. a. Write a balanced equation for the new reaction. b. What affect does this mutation have on the amount of ATP produced from one glucose molecule
A bacterium is discovered with a new mutated form of isocitrate dehydrogenase that catalyzes the same reaction but makes H₂; the reactant is isocitrate, and the product is alpha-ketoglutarate. As the proton count decreases, less ATP is produced.
What is the importance of the proton gradient in energy production?The proton gradient is formed during the electron transfer chain (ETC) by using all the NADH and FADH₂ that are derived from the glycolysis and kreb cycle. NADH and FADH₂, for example, are two compounds that travel through the different complexes to create the proton gradient, which later produces ATP; however, when H₂ is produced instead of NADH, less of a proton gradient is formed, and thus less ATP is produced. The equation is isocitrate+ NAD+ → alpha-ketoglutarate +CO₂ + H+
Hence, the reaction is composed of substrates isocitrate, NAD+, and products alpha-ketoglutarate, CO₂, and a proton (H+), which will be formed with significantly less ATP than the normal ATP produced from the one glucose.

Explanation:
Why are ferns and mosses poorly adapted to a terrestrial life
Answer:
Because they require a WATER medium for reproduction
Explanation:
Ferns are a group of living organisms under the division; Pteridophyta while mosses belong to the group Bryophyta. Mosses are considered primitive and non-vascular plants because they lack true stems, leaves and roots or vascular tissues. while ferns possess these organs, hence, are said to be vascular.
However, ferns and mosses are poorly adapted to a terrestrial life i.e. life on land because they both require a water medium for their motile male gametes to swim and fertilize their eggs (female gametes).

The amount of light, pressure, and temperature are examples of?
Explanation:
The answer is No. You know light from Stars travel in cold temperature of space and different pressure as they enter our planet after travelling many light year to reach us at the same the speed.
Light bends when entering a different medium(refraction). Even if the medium is same and the temperature is different it will get bend. As the 2 different temperature air behave like 2 mediums (Due to distribution of atoms ).
But light doesn't’ bend by heating or by putting pressure on it.

HOPE THIS HELPED HAVE A WONDERFULL DAY!
Two protein kinases, PK1 and PK2, work sequentially in an intracellular signaling pathway. You create cells that contain inactivating mutations in the genes that encode either PK1 or PK2 and find that these cells no longer respond to a particular extracellular signal. You also create cells containing a version of PK1 that is permanently active and find that the cells behave as though they are receiving the signal even when the signal is not present. When you introduce the permanently active version of PK1 into cells that have an inactivating mutation in PK2, you find that these cells also behave as though they are receiving the signal even when no signal is present.
Answer the following question in the space give.
A. From these results, does PK1 activate PK2, or does PK2 activate PK1? Explain your answer.
Answer:
The answer is "PK1 activates PK2"
Explanation:
All enzymes were required again for the transmission of a signal. If Pk1 is continuously active, pk2 will no longer be required, as per my theory, can trigger pk1, therefore the cells were if they amplify the message even when they're not active. But since both enzymes require regular copies together for transduction, pk2 is simple and pk1 requires to also be activated.

Explanation:
The choice that best describes the image shown above is it depicts asexual reproduction occurring through binary fission, a process that does not lead to genetic variation. The correct option is C.
What is asexual reproduction?Asexual reproduction is a mode of reproduction in which only one parent is needed. There are different types of asexual reproduction, like budding, vegetative reproduction, fragmentation, and binary fission.
This reproduction does not require the fusion of sperm and egg. The offspring is exactly identical to the parent. Many organisms reproduce in asexual reproduction, hydra, paramecium, starfish, etc.
Thus, the correct option is C. it depicts asexual reproduction occurring through binary fission, a process that does not lead to genetic variation.
