Answers

Answer 1

The pairing of complementary strands of DNA due to hydrogen bonding is called semi-conservative replication.

DNA replication

The biological process of creating two identical copies of DNA from a single original DNA molecule is known as DNA replication.  All living things replicate their DNA, which is the primary mechanism for biological inheritance. This is necessary for:

cell division during tissue development and repair, and it also guarantees that each new cell gets a copy of the DNA.

A double helix (two linear strands that run counterclockwise and twist together) of two complementary strands makes up DNA.

These strands are split apart in the replication process. The mechanism of semiconservative replication uses each strand of the original DNA molecule as a template to create its counterpart. The new helix will be made up of an original DNA strand as well as a freshly synthesized strand as a result of semi-conservative replication.

discuss differences between dicot and monocot plant in terms of external structure​

Answers

The difference between dicot and monocot plants in terms of external structure are:

1. Leaf structure:

Dicot leaves have a network of veins and tend to be arranged in pairs opposite each other on the stem. Monocot leaves, on the other hand, have parallel veins and are usually arranged in sets of three or more.

2. Flower structure:

Dicot flowers typically have four or five petals and sepals that are arranged in a spiral pattern.Monocot flowers usually have three petals and sepals that are arranged in a symmetrical pattern.

3. Root structure:

Dicot plants tend to have a taproot system, which is a single main root that branches off into smaller roots. Monocot plants typically have a fibrous root system, which is a network of many thin roots that branch off from the base of the plant.

4. The number of cotyledons:

Dicots typically have two cotyledons, or embryonic leaves, in the seed.Monocots typically have one cotyledon in the seed.

5. Stem structure:

Dicots have a ring of vascular bundles that surrounds the stem.Monocots have scattered vascular bundles throughout the stem.

Starting with the European settlers, humans have introduced earthworms from Europe and Asia into North American forests. These introductions continue through the transport of soil that contains non-native earthworms, such as during construction and through the release of non-native earthworms used for fishing. The effects of non-native earthworms are especially large in forests that did not have any native earthworms. For example, forests of the Great Lakes region did not previously have earthworms until humans introduced them. When non-native earthworms are introduced, the thick layer of leaves, known as leaf litter, covering the ground disappears quickly, thereby altering biogeochemical cycles.

What is a possible negative consequence of introducing the non-native earthworms to forests in the Great Lake regions?
PLease hurry
The earthworms reduce the resources available to other animals that eat dead plant matter.
The earthworm decreases the energy flow from one tropic level to the next.

If ouabain was used to block Na+–K+-ATPase pumps, A) the concentration of K+ would be equal on both sides of the membrane.
B) the cell would maintain steady state with a different membrane potential. C) the membrane potential would become more negative. D) Na+ would go to equilibrium across the cell membrane

Answers

If ouabain was used to block Na+–K+-ATPase pumps, the cell would maintain a steady state with different membrane potential. Here option B is the correct answer.

Ouabain is a drug that blocks the activity of the Na+–K+-ATPase pumps, which are responsible for pumping potassium ions (K+) into the cell and sodium ions (Na+) out of the cell.

By blocking these pumps, ouabain prevents the maintenance of the normal concentration gradient of K+ and Na+ across the cell membrane, and as a result, it alters the membrane potential. The membrane potential would not become more negative and the Na+ would not go to equilibrium across the cell membrane.

Humans selectively fish out the largest species from Earth's oceans, causing their populations to dwindle.

In eukaryotic cells, a terminator in mRNA synthesis is _____.

Answers

Hlnts stop codon particular nucleotide sequence in DNA, which tells the RNA polymerase to stop specific nucleotide sequence in mRNA to cease transcription, acts as a terminator in eukaryotic cells' mRNA synthesis.

Polymerase I transcribes ribosomal RNA, Polymerase II transcribes mRNA and miRNAs, and Polymerase III transcribes tRNA and other short RNAs in eukaryotes. Eukaryotes have three RNA polymerases, known as Polymerases I, II, and III. Although eukaryotic termination has not received as much attention as prokaryotic termination, the fundamental mechanisms are understood, and it has been noted that many eukaryotic RNA polymerase termination patterns exist. For instance, Polymerase III, like Rho-independent termination in prokaryotes, depends on a certain sequence and RNA secondary structure to cause transcript cleavage. Contrary to Polymerases I and II, which also call for the binding of termination factors, this is different.

Although both are termination factor dependent, Polymerases I and II employ different mechanisms to terminate transcription. Polymerase I uses a process similar to the prokaryotic Rho-dependent mechanism, whereas Polymerase II termination is more complex and involves two RNA polymerase-associated proteins, CPSF and CstF, which are responsible for recruiting the cleavage and polyadenylation enzymes, in a process that seems to couple termination with polyadenlyation.

Mycorrhizae is an adaptation that enhances the uptake of water and minerals by roots.

Mycorrhizae are the associations that exist between fungi and roots.

In around 90% of all terrestrial plants, these symbiotic relationships can be discovered.

A root-like structure and a network of mycelium that spreads into the soil outside of the tree roots make up the mycorrhizal fungi.

By taking in nutrients, this mycelium then transfers those nutrients back towards the host plant.

The absorption surface area of the root system grows as a result. The plant can get more moisture and nutrients because its mycorrhizae, or roots, are significantly larger. This is crucial for phosphorus uptake, which is one of the main nutrients that plants need.
