Why can't blizzards cause secondary succession?
If I had to guess I would say because blizzards happen in the winter and things don't grow in the winter, therefore secondary succession cannot happen as recolonization with plants cannot happen because most plants don't grow in the winter.
Last semester I learned about succession so I'm basing my answer on the stuff I learned.
Hope this helps! :)
What characterizes a climax community in a forest?
When Mendel performed his experiments, only one trait appeared in the F1 generation, (in this case, round peas) and the other trait (wrinkled peas) had seemingly disappeared. However, once he let the plants of the F1 generation self-fertilize, the wrinkled peas reappeared! If you were Mendel, how would you explain this phenomenon
Answer:
See the answer below
Explanation:
The explanation I would give to the phenomenon is that the round trait in peas completely covers or nullify the wrinkled trait when they are together. In order words, whenever a single the allele of both trait come together to form a new trait, the round trait allele dominates and mask the expression of the allele of the wrinkled trait.
This is what Mendel explained and dominance/recessive effects. The round trait was dominant over the wrinkled trait while the wrinkled trait was said to be recessive and can only be expressed when alone.

What is the role of carbon storage in organisms?? Plz answer fast in paragraph form if possible
Biological carbon storage happens when the carbon is stored in natural environment in animals and plants. This process includes what are known as carbon sinks, such as forests, grasslands, oceans, and other bodies of water.
What is Carbon storage?Carbon capture and storage is an attempt to remove the carbon dioxide gas from atmosphere after burning gas, oil, coal, or biomass before it actually enters the atmosphere, and to store it in the environment in various forms. Carbon storage has a success rate of between 50% to 68% of captured carbon, while aspirations of a 90% or 100% capture rate have not been achieved properly.
Carbon storage is carbon which is not emitted into the atmosphere. Less amount of carbon in the atmosphere will reduce the greenhouse gas effect and thus also lessens the impact of climate change and global warming.

A punch is painful, while a hug is not, because a punch produces _______ action potentials from each sensory neuron. A) stronger B) more frequent C) faster-moving D) fewer
Answer:
B) more frequent
Explanation:
This occurs because a punch produces more frequent action potentials from each sensory neuron. This is only caused when there are rapid and sudden changes. A punch is fast and causes very sudden changes when the punch comes into contact with the human body. This therefore, causes these fast and sudden changes which fire very frequently from each sensory neuron. A hug is soft and does not affect the human body in such a sudden way so it does not cause frequent action potentials.
1. Robin carries the trash from the house to the garbage can outside. Which statement best describes the science of what he did?
He would use less energy if he were to move the garbage faster
He used energy to carry the garbage.
He did not have to work because garbage is light.
He caused the garbage to have potential energy when it moved.
Answer:
He used energy to carry the garbage.
Explanation:
Energy is the ability to do work. When work is done, energy is expended during the process. Work is done if the force applied on an object moves that object through a distance.
In the case where Robin carries the trash from the house to the garbage can outside, work is done because, the force applied by Robin on the trash effectively helps to move the trash from inside the house to the garbage can outside the house. During the process of moving the trash, Robin expends or uses energy to do the work.
From the given options:
He would use less energy if he were to move the garbage faster is wrong because an increase in speed results in an increase in energy
He used energy to carry the garbage is correct because energy is the ability to do work
He did not have to work because garbage is light is wrong because as long as an object is moved a distance, work is done irrespective of the mass of the object.
He caused the garbage to have potential energy when it moved can only be true if he had raised the garbage from the floor to a height above the ground. However, he only moved it fro inside to outside the house.
The respiratory rate times the tidal volume corrected for the dead air space in the lungs is the __________.
a. vital capacity
b. respiratory minute volume
c. pulmonary ventilation rate
d. alveolar ventilation rate
e. external respiration rate
Answer:
d. alveolar ventilation rate
Explanation:
Alveolar Ventilation rate (AVR) refers to the rate of airflow that reaches the alveoli which is available for gas exchange with the blood in a given unit of time. AVR is generally calculated as the amount in millimeters of air expired that equilibrates (i.e., exchanges) with alveolar gas per min unit (ml/min). AVR is affected by breathing frequency, tidal volume ( i.e., the normal amount of air between inhalation and exhalation), and the amount of dead space in the lungs.

Answer:
Unavailability of food decrease their population.
Explanation:
The population of Galapagos Finches decreases because of unavailability of food. Galapagos Finches feeds on a specific insects whose population decreases on that Island that leads to the death of the Galapagos Finches and they decrease in number. Positive population growth occurs only if more food is available to the Finches or they adapt another food item for themselves which fulfill their need of food.

Imagine that you are standing in a field and you see a group of butterflies. You notice an individual butterfly that looks significantly different from the others in the population. Its difference allows the butterfly to escape predation more efficiently than the other butterflies. How might this trait have arisen in the individual
Answer:
Explanation:
Mutation is a sudden change in the genome of an organism that is heritable.
Mutation occur due to a spontaneous change in the sequence of a gene, it can occur during DNA (deoxyribonucliec acid) replication, mitosis, meiosis. Some mutation are beneficial, some are detrimental while some could be deleterious. Mutation is a rare occurrence usually one in several hundreds or thousand
The unique traits that was reveal in the bird is due to mutation, it is beneficial because it kept it away from predation it is a rare case.
What is phagocytosis in regard to the immune system of humans?
Answer:
Phagocytosis is the process of introducing larger particles into a larger cell. The process takes place by twisting the cell membrane of the "host" and enveloping the particles with a phagocytic bubble. Leukocytes use phagocytosis to take in and incapacitate bacteria that enter our body, so phagocytosis plays an important role in the immune system, as it prevents harmful cells from affecting humans.
Answer:
the process by which neutrophils ingest a bacterium
Explanation:
Neutrophils ingest bacteria via a process known as phagocytosis, or "cell eating." (also, I took the quiz)
Explain the three main ways energy is transferred, provide examples of each
Answer:
Conduction: It is when heat energy moves from place to place.
Convection: It is when fluid, such as air or a liquid, is heated and then travels away from the source, it carries the thermal energy.
Radiation: It is a transfer of heat by electromagnetic wave
Explanation:
Answer:
Conduction is the transfer of energy from one molecule to the next by direct contact.
Convection is the movement of heat by a fluid such as air or water.
Radiation is the transfer of heat by electromagnetic waves.
Explanation:
Convection is known as the process of transferring energy or heat through a fluid (liquids or gasses) from high temperatures to low temperatures. Convection is known as one of the three types of heat energy transfer. The other two types of heat energy transfer are conduction and radiation. Conduction is known as the transfer of heat between anatomies that are directly touching each other. while, during radiation, the energy is discharged in the shape of electromagnetic waves.
As for the molecular motion in liquids, it is the result of convective heat energy transfer. Furthermore, the movement of the molecules increases as the temperature of the molecules is increasing. The result of this is that the molecules seem to move away from each other. The motion of the molecules is what is responsible for the transfer of heat.

How might a sudden cold front limit population growth of newborn offspring?"" HELP PLEASE
Answer:
The correct answer is - they may not be able to survive at such a temperature.
Explanation:
A Cold front is a weather change when a cooler air mass moves into warmer air that leads to a sudden drop in temperature following by the cyclone, heavy rainfall and hail.
These sudden changes and heavy rain with storms and cyclones can limit the population growth of newborn offspring as they may not able to survive in such a sudden temperature drop.
Which is a difference between active and passive transport?
A. Eukaryotes are capable of active transport, while prokaryotes are capable of passive transport.
B. Cells only carry out active transport when they need to move, while passive transport occurs constantly.
C. Active transport requires ATP, while passive transport does not.
D. Cells with mitochondria carry out active transport, while cells without mitochondria carry out passive transport.
The difference between active and passive transports is that active transport requires ATP while passive transport does not. the correct option would be C.
Active transports are the movement of materials in and out of the cell that requires the expedition of energy. The energy is usually in the form of Adenosine Triphosphate (ATP).
Active transport is unlike passive transport because the latter requires no energy. In other words, passive transports are spontaneous.
Active transport usually involves the movement of materials against their concentration gradients while passive transport is the complete opposite.
Examples of active transport include the sodium-potassium pump, movement of amino acids in the intestinal tracts of man, etc while examples of passive transport include simple diffusion of oxygen to the alveolar walls in the lung.
