Answer:

DNA Helicase is the enzyme that unwinds the double-stranded DNA into two single strands forming a replication fork.

DNA topoisomerase II or Gyrase is the enzyme responsible for relieving or relaxing the topological stress caused by the unwinding of DNA double strands.

DNA polymerase III is the primary replication enzyme. It is responsible for adding deoxyribonucleotides to the RNA primer both in the continuous or leading strand synthesis as well as in the discontinuous or lagging strand synthesis of DNA.

Primase is the enzyme responsible for the synthesis of the RNA primer (a short segment of RNA) to which deoxyribonucleotides are added.

DNA polymerase I is responsible removing and replacing the RNA primers with DNA in the newly DNA strands.

DNA Ligase is the enzyme responsible for sealing the gaps in the DNA due to broken phosphodiester bonds after the removal of the RNA primer.

Explanation:

The sketch of the replication fork of bacterial DNA showing where one strand is being replicated discontinuously and the other is being replicated continuously, as well as the different enzymes involved and their location of activity is found in the attachment below.

DNA replication occurs in the 5' to 3' direction by DNinA polymerases.

Continous DNA replication occurs in same direction as the direction as the replication fork, in the 5' to 3' direction.

The discontinuous replication occurs in fragments of DNA known as Okazaki fragments which are then ligated by DNA ligase.

Answer:

64

Explanation:

Since the cell has two chromosomes and a diploid number of 2, in each generation, the cell doubles. In the first generation, we have two cells, in the second generation, we have 2 × 2 cells ,in the third generation, we have 2 × 2 × 2 cells. It follows that we have 2ⁿ cells in each generation where n represents the generation.

So, in the fifth generation, n = 5, so the number of cells is 2⁵ =  32.

Since we have 2 chromosomes in each cell, the number of chromosomes in the 32 cells in the 5th generation is 2 × 32 = 64 chromosomes.

Answer:

Cell division

Explanation:

Everything starts from the union of a sperm and an egg, which gives rise to a cell, which has to become an adult organism. For this, this cell divides in such a way that in each division exactly the same genetic information is maintained. The cell is the reproductive unit of living beings. Throughout its life the cells are nourished and increase in size. When a cell reaches the appropriate size, it usually gives rise to two cells similar to the original cell. Cell Theory is one of the fundamental bases of biology and it is where the base of the constitution of living beings and the fundamental role of cells in them is summarized. It is formulated in the first place thanks to observations and formulations of Theodor Schwann ( physiologist) and Matthias Schleiden (botanist).The current third principle of cell theory, formulates that a cell comes from another cell, by cell division or by formation from stem cells. The oldest and most primitive cells in the world are prokaryotes (without a cell nucleus).

Answer:

c

Explanation: all other traits are irrelevant and could reply to any part o the food chain, c means that the plats have dropped, meaning that the things that eat the plants wot be able to eat the plants, (primary consumers)and the secondary consumers wont be able to eat the primary consumers,then the tertiary consumers wont be able to eat the secondary consumers. In simpler terms it would cause a chain reaction that would detonate the whole foodchain.

Answer:

creating a hypothesis

Explanation:

The scientific method is a logical and systematic procedure used to understand phenomena from the real world. The scientific method involves several sequential steps: 1-to observe and pose a question on a particular phenomenon from the real world, 2-to raise a hypothesis or 'explanation' to these observations (this explanation allows to obtain a predictive pattern in order to explain further observations), 3-to test the hypothesis by experimental procedures or further empirical observations, 4-to analyze and interpret data (results), and 5- to reach to a conclusion that confirms or rejects the working hypothesis. A good hypothesis must be 1-plausible (i.e., it is scientifically adequate and appropriate), 2-falsifiable (i.e., it may have a negative answer) and 3-testable (i.e., it must be proven by scientific data).

Bob Harmon discovered the best-preserved Tyrannosaurus rex skeleton ever found and is the first scientist to identify the gender of a T. rex, the organ system is the skeletal system, as it includes the bones that are present in Option A.

The skeletal system, which provides structural support, is important for animals as it protects vital organs, supports muscles, and helps in movement. Also, the bones synthesize the blood cells, such as the red blood cells, which carry nutrients and oxygen, it also maintains the individual's balance and posture and provides a veil over the fossil records.

Answer:

The statement which best describes about ecological succession is that the one which states that It is a series of 'rapid changes' in an ecosystem.

Ecological succession is caused by human intervention. Therefore, the correct statement is option B.

Ecological succession is a natural process that takes place after an ecosystem is disturbed by something like a fire, flood, or human activity. It is an anticipated example of changes in the species synthesis and local area design of an environment over the long haul.

Ecological succession is a process in which the ecosystem's physical and biological characteristics undergo a series of gradual shifts over many years or even centuries.

From the pioneer stage to the climax stage, where the ecosystem reaches a relatively stable state, ecological succession involves a series of stages. Different species of plants and animals replace one another during ecological succession, resulting in shifts in the ecosystem's physical and biological conditions.

Therefore, ecological succession is caused due to human intervention where the ecosystem is disturbed by a fire, flood, or human activity.

Answer

A cladogram is a visual chart orrepresentation of cladistics. They consist of horizontal or vertical lines connecting various organisms. These different lines branch off from a common point on the cladogram. These branch points represent a common ancestor shared by the organisms that emanate from the branch point.

The junctions of a cladogram represent the branching points in evolutionary relationships between different groups of organisms, and the cladogram is a type of evolutionary tree.

The junctions in a cladogram can also be used to infer the evolutionary relationships between different groups of organisms based on the pattern of shared derived characters, and the branching points in a cladogram represent the divergence of lineages. The presence of a derived character in multiple groups at a junction in a cladogram indicates that the character was present in the ancestral group, and this is widely used in evolutionary biology.

Hence, the junctions of a cladogram represent the branching points in evolutionary relationships between different groups of organisms, and the cladogram is a type of evolutionary tree.

Answer:

B. The population size will decrease

Explanation:

Abiotic factors may include temperature, sunlight and water. If conditions are too cold for the organisms living there, they may perish. If the amount of sunlight decreases, plants will not be able to produce enough glucose through photosynthesis. If the amount of water decreases plants may bot have enough water to photosynthesise and animals will have to compete for water.

Temperature, sunlight, and water are abiotic. Organisms may die in frigid environments. Therefore, option (B) is correct answer.

Abiotic and biotic environmental factors fall into the category of population-influencing factors. The non-living physical and chemical components that make up an ecosystem, such as temperature, pH, sunlight, shelter, and day length, are referred to as abiotic variables.

Cold conditions can cause the death of organisms. If sunlight dwindles, photosynthesis cannot produce enough glucose. Lack of water may make it difficult for plants to photosynthesize, forcing animals to compete for it.

Answer:

This question lacks options, options are: Mr. M's cells are depolarizing too easily. Blocking Nat channels will make it harder for them to depolarize, bringing their sensitivity back to normal O Mr. M has too little K* leaving his cells, so we need to block the Nat channels so the Kt channels can stay open and his cells can repolarize properly. Mr. M has too little K* leaving his cells, so we need to block the Nat channels so the Na /K+ ATPase can move Kt out of the cell effectively O Blocking Na* channels cannot help- it will only make his cells fire less, and he already has a weak heartbeat. Mr. M's cells are not repolarizing properly. Blocking Nat channels will help them repolarize normally, bringing their resting potential back to normal.

The correct answer is ''Mr. M's cells are depolarizing too easily. Blocking Na+ channels will make it harder for them to depolarize, bringing their sensitivity back to normal.''

Explanation:

Calcium administration is an emerging treatment modality aimed at restoring the transmembrane electrical gradient of cardiac myocytes. It probably achieves this goal by reducing the resting membrane potential of cells. Calcium antagonizes the effect of hyperkalemia on cardiac conduction, that is, it antagonizes the effects of K on the heart. Its onset of action is immediate, in a few minutes. Calcium gluconate antagonizes the excitability of the cardiac membrane, that is, it decreases the excitability of the membrane and it does not affect serum levels, it is generally accepted that calcium should be administered when there are ECG changes associated with hyperkalemia.
