Final answer:
The absence of symbiotic fungi from the soil would severely disrupt plant growth due to a lack of essential nutrient uptake, cause a build-up of undecomposed organic material, and negatively impact biogeochemical cycles and ecosystem health.
Explanation:
If symbiotic fungi were absent from the soil, the impact on plant growth would be significant. Plants form relationships with fungi, including structures known as mycorrhizae, which are critical for nutrient uptake. Fungi assist in acquiring nutrients such as phosphorus and nitrogen that plants need to grow. Without these symbiotic partnerships, plants would struggle to obtain these essential nutrients, leading to poorer growth and reduced vitality. Furthermore, fungi play a crucial role in decomposing organic matter, recycling nutrients back into the soil. Without fungi, the accumulation of undecomposed organic material would disrupt biogeochemical cycles, resulting in a build-up of carbon in dead matter and waste, and impair other nutrient cycles, such as nitrogen fixation and phosphorus release. Over time, the absence of fungi could lead to a decline in the structural diversity of forests and other habitats, negatively impacting the broader ecosystem and potentially leading to the extinction of numerous species.

describe how waves superpose on each other using specific examples from two types of waves
During superposition of a wave such as that of the oceans, when the crest and the trough meet, then they cancel out into the period. If two crests meet up, they add up to a crest that’s equivalent to the summation of their amplitudes. This is also true when two troughs meet up.
Why do you think there are fewer heart transplants performed each year than kidney transplants?
This is because, people, generally, have two kidneys and are also able to function properly with one functional kidney. Therefore it is easier to perform kidney surgery without putting the patient’s life at risk as compared to heart surgery. Everyone has one heart, a critical organ whose surgery has to be well planned and done only if the risk of not doing the surgery outweighs that of doing the surgery.
The diversity found among dna molecules is due to the sequence of _______.
Final answer:
The diversity among DNA molecules comes from the sequence of nucleotides, which can create a vast number of combinations despite having only four types. Mutations contribute to this diversity by altering DNA sequences, leading to variations among individuals.
Explanation:
The diversity found among DNA molecules is due to the sequence of nucleotides. Even though DNA consists of only four different bases — adenine (A), cytosine (C), guanine (G), and thymine (T) — the arrangement of these nucleotides can vary infinitely. Each organism has a unique DNA sequence, which serves as a genetic blueprint vital for its development, functioning, and reproduction. This genetic diversity is the foundation of the wide variety of life on Earth.
Mutations are changes in the nucleotide sequence that can occur spontaneously or due to external factors like radiation or chemicals. These mutations can lead to variations among individuals within the same species, contributing to the biological diversity we observe. Such variations include single nucleotide polymorphisms (SNPs), which are differences in single nucleotides between individuals, further highlighting the role of nucleotide sequences in genetic diversity.

. Many cities have “combined” sewers. In good weather, these systems funnel sewage to treatment plants. During rainstorms street runoff is combined with sewage. Combined sewers in cities can be problematic because _____. the sewers cannot handle the volume of waste from street runoff and sewage sewers are often blocked by trash that people have thrown into them street runoff cannot flow into the sewers and be safely taken to treatment plants street runoff often causes the sewers to deteriorate
The given blank can be filled with the sewers cannot handle the volume of waste from street runoff and sewage.
The combined sewage system is very popular in many big cities. The sewage system handles all the sewage combining from the houses. During the rainy season, the water flows in the sewer, causing the overflow of the sewers and spread of water in the nearby regions.

Compare and contrast Broca’s area and Wernicke’s area. Describe how each was discovered.
Answer:
Broca’s area is the area of the brain that controls speech production. It was discovered by Paul Broca after he discovered a lesion in the left frontal lobe of a patient who could not speak. Wernicke’s area is the area of the brain that controls speech comprehension. Like Broca’s area, it also plays a role in speech production. Wernicke’s area was discovered by Carl Wernicke, who found that damage to the left temporal lobe resulted in speech deficits.

Which of the following best describes the process of diffusion?
A. Diffusion is the movement of molecules from an area of higher concentration to one of lower concentration by random molecular motion.
B. Diffusion is the movement of molecules from an area of lower concentration to one of higher concentration by random molecular motion.
C. Diffusion is the movement of molecules from an area of lower concentration to one of higher concentration caused by an input of energy to the system.
D. Diffusion is the movement of molecules from an area of higher concentration to one of lower concentration caused by an input of energy to the system.
Diffusion is best described as the process where molecules move from an area of higher concentration to one of lower concentration by random molecular motion, until there's uniform distribution. It does not need an energy input.
Explanation:The best choice that describes the process of diffusion is option A. Diffusion is the movement of molecules from an area of higher concentration to one of lower concentration, driven by random molecular motion. This tends to happen until the concentration of molecules is uniform throughout. It is a naturally occurring process and does not need an input of energy from the system. For example, if you were to open a bottle of perfume in a room, it would eventually spread out, or diffuse, until the smell is evenly distributed in the room.

Out of the following given choices;
A)the offspring will have traits of both parents.
B)there is genetic variation among the offspring.
C)all the offspring will be genetically identical.
D)none of the offspring will be genetically like the parents.
The answer is C. This is because, in binary fusion, they are no formation of gametes. Therefore genetic variability that comes with sexual reproduction not found in asexual reproduction. Mostly, the offspring buds off from the parent or grows from a split part of the parent. Therefore the offspring is genetically identical to the parent

An isotope has the same ________, but a different ________
Answers
A) atomic number, mass number
B) Mass number, atomic number
C) number of neutrons, number of protons
D) number of protons, number of electrons
Answer:
Atomic number, mass number.
Explanation:
The three sub atomic particles of the atoms are electron, proton and neutron. The atomic number of the element is equal to the number of protons of the element.
Isotopes may be defined as the elements that have the same atomic but different mass number. The simplest example of isotopes are protium, deuterium and tritium. They have the same atomic number 1. These are the isotopes of hydrogen.
Thus, the correct answer is option (A).
Thermohaline circulation is movement of seawater due to differences in what two properties?
1)
density and temperature
2)
salinity and temperature
3)
temperature and depth
4)
salinity and density
Answer is 2. Salinity and temperature.
The movement of water in the ocean is called thermohaline circulation. This circulation is depends on temperature and salinity. These two factors together affect the density of seawater. More dense seawater sinks below less dense seawater and thus the oceans circulate partially based upon their temperature and salinity. Heat from the Sun affects temperature of seawater. Surface seawater gets more heat near the equator than near the poles, and similarly more in the summer than in the winter. Salinity of seawater is affected by evaporation, precipitation, ice formation, and ice melting. Evaporation increases the salinity of seawater because when seawater evaporates, the salts are left behind, thus increasing their concentration. Precipitation and river input decrease salinity because the input of freshwater dilutes the salts in seawater, thus decreasing their concentration.
