What is the difference between blue green and fungi?
Blue-green algae are photosynthetic prokaryotes, while fungi are eukaryotes that obtain nutrition through absorption.
Blue-green algae and fungi are both organisms, but they belong to different domains and have distinct characteristics. Blue-green algae, also known as cyanobacteria, are classified under the domain Bacteria, while fungi belong to the domain Eukarya.
Blue-green algae are prokaryotic organisms, lacking a true nucleus and membrane-bound organelles. They obtain energy through photosynthesis and are capable of converting sunlight into chemical energy. They typically inhabit aquatic environments, such as lakes, ponds, and oceans, and some species can fix atmospheric nitrogen.
On the other hand, fungi are eukaryotic organisms with a distinct nucleus and membrane-bound organelles. They obtain nutrition by absorbing organic matter from their surroundings. Fungi play crucial roles in decomposition and nutrient cycling in ecosystems. They can be found in various habitats, including soil, plants, and even as symbiotic partners with other organisms, such as in mycorrhizal associations.
In summary, the primary differences between blue-green algae and fungi lie in their cellular structure, mode of nutrition, and classification. While blue-green algae are photosynthetic prokaryotes, fungi are eukaryotes that obtain nutrition through absorption. Understanding these distinctions helps in appreciating the diversity and ecological significance of these two groups of organisms.

in each case , state and explain the effect on fermentation of raising the temperature from 20 degrees to 45 degrees
Beyond certain thresholds, the heat can denature enzymes, kill yeast cells, and produce undesirable flavors. It is essential to maintain an optimal temperature range specific to the type of fermentation and the microorganisms involved to ensure successful and high-quality fermentation outcomes
Raising the temperature from 20 degrees Celsius to 45 degrees Celsius would have the following effects on fermentation:
1. Increased fermentation rate: The rate of fermentation is typically temperature-dependent. Increasing the temperature from 20 to 45 degrees Celsius would accelerate the metabolic reactions involved in fermentation. This would result in an increase in the rate at which sugars are converted into alcohol or acids, depending on the type of fermentation.
2. Accelerated yeast activity: Fermentation is often carried out by yeast, and yeast activity is highly influenced by temperature. Increasing the temperature to 45 degrees Celsius would speed up the metabolic processes within the yeast cells, leading to increased yeast activity and faster fermentation.
3. Shortened fermentation time: Due to the increased fermentation rate and accelerated yeast activity, the overall fermentation process would be shortened. The higher temperature would promote faster consumption of sugars and production of desired fermentation products.

In a population of 13 Bio 1 lab students, p = 0.146, how many more students must complete their eval for the p allele to become fixed?
In a population, 12 Students must complete their eval for the p allele to become fixed.
To determine how many more students must complete their evaluation for the p allele to become fixed, we need to calculate the frequency of the p allele in the current population. We can do this using the formula:
p = number of p alleles / total number of alleles
Since we are dealing with a diploid organism, each individual has two alleles, so the total number of alleles in the population is 26 (13 students x 2 alleles per student). If p = 0.146, then the number of p alleles in the population is:
number of p alleles = p x total number of alleles
number of p alleles = 0.146 x 26
number of p alleles = 3.796
We can't have a fraction of an allele, so we round up to 4 p alleles in the population. To calculate how many more students must complete their evaluation for the p allele to become fixed, we need to consider that fixation occurs when the frequency of one allele is 1 (or 100%). Since there are only two alleles in this population (let's call the other allele q), the frequency of q is:
q = 1 - p
q = 1 - 0.146
q = 0.854
So, if the p allele is to become fixed, all individuals in the population must have the p allele. Currently, there are 4 p alleles in the population, which means there are 22 q alleles (since there are 26 total alleles). Each student has two alleles, so there are still 11 students whose allele frequencies are unknown. To calculate how many more students must have the p allele for it to become fixed, we need to calculate the number of q alleles that remain:
number of q alleles = q x total number of alleles
number of q alleles = 0.854 x 26
number of q alleles = 22.204
Again, we can't have a fraction of an allele, so we round up to 23 q alleles. This means that at least 12 students (since each student has two alleles) must have the p allele for it to become fixed, which will result in a p frequency of 1 (or 100%) and a q frequency of 0.

Based upon data from the Human Microbiome Project (HMP), define microbial antagonism and discuss how the various microbial populations keep each other "in check" with consequences for human health.
Answer:
Suppression of one microorganism by another microorganism.
Explanation:
Microbial antagonism is the suppression of one microorganism by another microorganism. For every organism, God creates another organism in order to control its growth and population. So harmful microorganisms that cause diseases in human can be controlled by another beneficial microorganism. If the beneficial microorganisms are removed from the environment, the harmful microorganisms causes more damage to human and their property.
Microbial antagonism refers to competition between microorganisms in the same environment. This limits the growth of the microorganism population, protecting human health.
We can arrive at this answer because:
Microbial antagonism occurs when two different species of microorganisms are in the same environment and compete for the same resources.This competition limits the growth of the two species and can even suppress the population of each other.This type of biological system is beneficial in keeping populations of microorganisms, which can have negative effects on humans, under control, preventing proliferation, and maintaining human health and integrity.

According to Stevens the intensity of a sensation is:
A) directly proportional to the intensity of the reflected sound-wave.
B) decreased as the intensity of the physical stimulus increases.
C) directly proportional to the intensity of the physical stimulus raised by a constant power (exponent).
D) directly proportional to the logarithm of the intensity of the physical stimulus raised by a constant power.
Stevens says that the intensity of a feeling is: decreased as the physical stimulus became more intense.
Option B is correct.
How does an electric field work?The force per unit charge that is applied to a positive test charge that is at rest at that location is represented by the electric field, which is described mathematically as a vector field that can be connected to any point in space. An electric field can be created by either the electric charge or time-varying magnetic fields.
What is intensity ?The intensity (I) of a wave is determined by dividing the surface area over which the energy is dispersed by its rate of energy transfer. To put it another way, intensity refers to the rate of energy flow per unit area. The amount per unit region is estimated by force. Intensity is typically used to describe the size of waves per unit area. Another way to think about a wave's strength is its power per unit of area over time.
Therefore, Stevens asserts that the intensity of a sensation is as follows: diminished as the force of the actual improvement increments.
