Explanation:
The EKG is hooked up, and Mr. M's trace looks very abnormal. His heart rate is low. The T wave, which indicates repolarization of the ventricles, is unusually large and pointed and the QRS wave, which indicates the depolarization impulse’s passage through the ventricles, is widened or slowed. "That's a classic EKG for hyperkalemia (high blood potassium)!" The doctor gives Mr. M an injection of calcium gluconate. Calcium ions block the Na+ channels on nerve and muscle cells. How will this help counteract the effects of high blood K+? g
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.

How does a decrease in abiotic resources impact the population growth in an ecosystem?
A. The population size will increase
B. The population size will decrease
C. The population size will not change
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.
What are abiotic resources?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.

On May 18,1980, Mount St. Helens in the state of Washington erupted with the force of a hydrogen bomb. The volcano had been dormant for over 120 years, but now 57 people were dead; forests and lakes were totally destroyed, including nearby Spirit Lake, which became a mud hole. The blast leveled trees in areas over 10 miles from the crater and ash deposits suffocated life on the mountain. However, within weeks, mammals that had taken shelter underground started to appear in the area, and now, over thirty years later, many areas of the mountain are colonized with a large variety of plant and animal life. How does an area move from a sterile, barren wilderness to one full of life
Answer:
The correct answer is - Ecological Succession.
Explanation:
Ecological succession is a change in the species or biodiversity over time by the increase in the vegetation or growth of the community. This takes place after a natural disaster or any event that causes nudation or complete removal of species or comunities from an area such as volcanic eruption.
It starts with nudation then invaded with primary successors and then ecological conditions lead to invading more species and the third stage would be competition and interaction between a component of the species and vegetation then stable.

Sketch a replication fork of bacterial DNA in which one strand is being replicated discontinuously and the other is being replicated continuously. List six different enzyme activities associated with the replication process, identify the function of each activity, and show where each would be located on the replication fork. In addition, identify the following features on your sketch: DNA template, RNA primer, Okazaki fragments, and single-stranded DNA binding protein.
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.

Which statement best describes ecological succession?
A. It is always caused by human intervention.
B. It occurs after a disturbance.
C. It never occurs in a predictable pattern.
D. It is a series of rapid changes in an ecosystem.
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.
What is ecological succession?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.

Lewis and Benny have been studying about the rate of photosynthesis in plants
and are planning an investigation. They each conducted research and wrote
down their observations. They made a list of investigative steps: drawn
conclusions, measure, create a hypothesis, and interpret data. Which step should
occur first in Lewis and Benny's investigation?
interpreting data
writing a conclusion
creating a hypothesis
taking measurements
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).

What process is responsible for satisfying the third tenet of the Cell Theory, which states that new cells originate from other living cells?
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).
