Which if the following is a biotic factor in a deciduous forest biome?
A Temperature
B Precipitation (rain)
C Soil
D Trees
Answer:
[tex]\boxed {\boxed {\sf D. \ Trees}}[/tex]
Explanation:
A biotic factor is a living part of an ecosystem. Animals, plants, fungi, and bacteria are all examples.
Let's examine the list we are given. We have temperature, precipitation (rain), soil, and trees.
Temperature, precipitation, and soil are not living. These are all abiotic factors. They are still part of the ecosystem, but they are not alive. So, that leaves trees, which are plants, as the biotic factor in a deciduous forest biome.
) Name the 3 polymers of carbohydrates and describe the structure and function of each of them.
Answer:
The correct answer is - starch, glycogen, and cellulose.
Explanation:
Polysaccharides are the name of the polymers of carbohydrates that have long chains of monosaccharides connected together. Carbohydrates like starch, glycogen, cellulose, are long polymers of monosaccharides.
Starch produced by plants and is a long-term storage form of sugar. Starch is also the major source of food and is made of two major polysaccharides amylose, linear polysaccharide of α-1,4-linked d-glucopyranose with a few branches of α-1,6 linkages, amylopectin, amylopectin possesses a branched structure with α1–4 as well as α1–6 glycosidic linkages.
Glycogen is a polymer of glucose residue with α-1,4 glycosidic bonds and after every 10 residues, there is branches off via α-1,6 glycosidic linkages. It is the second storage form of energy.
Cellulose is the structural polymer that is made up of unbranched chains of glucose molecules linked via beta 1-4 glycosidic bonds every second glucose is inverted in this polysaccharide.

Individuals in a population of purple people earters are polymorphic at a single locus that leads to variation in purple people eater pup viability. 45% of the pups with genotype PP are viable, 54% of pups with genotype Pp are viable, but only 4% of pups with genotype pp are viable. What model of natural selection best fits these data
Answer:
The correct answer is - overdominance.
Explanation:
In the given question, genotype Pp is a heterozygote condition that has a 54% survival rate or fitness thus these individual people get more chance of mating and increase in number as compared to the other two conditions of PP or pp traits where PP has 45% survivability, less than heterozygous condition and more than pp that has only 4% rate.
It results in a normalizing selection model of natural selection as a moderate trait, that is heterozygote, is selected. Thus, the selection of overdominance which means heterozygote condition produces a better phenotype than PP or pp parents is heterosis.
What happened to make the K-T boundary?
Answer:
A meteorite big enough to be called a small asteroid hit Earth precisely at the time of the K-T extinction. The evidence for the impact was first discovered by Walter Alvarez and colleagues. They found that rocks laid down precisely at the K-T boundary contain extraordinary amounts of the metal iridium
Explanation:
How does this affect the change?
Answer: B. It sped up evolutionary change by increasing genetic variation.
Explanation:
Evolution works when organisms with genes that are better suited to the environment pass on their genes to future generations.
Sexual reproduction sped up this process because it allowed for genetic variation as genes from the two mates would be passed on the next generation instead of one organism as had been the case with asexual production.
With genes from both mates mixing up and going into the next generation, more genetic variations were produced which allowed for the organisms to better adapt to the environment.

Answer:
Tt
Explanation:
Hello. I believe that you are only referring to question 2, since question 3 does not present all the answer options. As such, the offspring of a cross between a tall pea plant (TT) and a low pea plant (tt) would be completely "Tt."
To achieve this result, you must make a Punnett Square, which is a frame that allows you to combine the alleles of the parents in a cross to project the alleles of the offspring.
Alleles are those characterized by the letters associated with characteristics. As you saw in the question above, tall pea plants have "TT" alleles that are dominant alleles, while low pea plants have "tt" alleles that are recessive alleles. In this case, to use Punnett Square, you must put the alleles of one parent in the first row and the allele of the other parent in the first column. Then just combine each allele, as shown below:
T T
t Tt Tt
t Tt Tt
As you can see all the offspring will have the "Tt" alleles. This means that the entire offspring will be tall pea plants. This is because the recessive allele "t", which is related to pea plants, can only be expressed in the presence of another recessive allele. However, the dominant "T" allele, which is associated with tall pea plants, can be expressed in any situation.
Why is global warning considered a controversial issue?
answer: The global warming controversy concerns the public debate over whether global warming is occurring, how much has occurred in modern times, what has caused it, what its effects will be, whether any action can or should be taken to curb it, and if so what that action should be. In the scientific literature, there is a strong consensus that global surface temperatures have increased in recent decades and that the trend is caused by human-induced emissions of greenhouse gases.[1][2][3][4][5][6] No scientific body of national or international standing disagrees with this view,[7] though a few organizations with members in extractive industries hold non-committal positions,[8] and some have attempted to convince the public that climate change is not happening, or if the climate is changing it is not because of human influence,[9] attempting to sow doubt in the scientific consensus.

Which event might disrupt a stable ecosystem?
A
Green plants use chlorophyll to produce food.
B
An invasive species enters the environment.
Consumers eat producers.
D
Predators kill prey.
Answer:
An invasive species enters the environment.
Explanation:
All other answers already naturally happen in an environment so they are stable. But if an invasive species enters, the ecosystem will be less stable because invasive species dominate ecosystems which isn't natural to the animals that live there. So for example, if someone introduced an invasive species to the ecosystem, it can cause many changes like if it was a predator, there'll be less primary consumers (the animals that eat plants) because the invasive species isn't natural to them.
Answer:
B
Explanation:
An invasive species enters the environment is the correct answer.

The original source of new alleles, upon which selection operates, is mutation, a random event that occurs without regard to selectional value in the organism. Although many model organisms have been used to study mutational events in populations, some investigators have developed abiotic molecular models. Soll et al. (2006. Genetics 175: 267-275) examined one such model to study the relationship between both deleterious and advantageous mutations and population size in a ligase molecule composed of RNA (a ribozyme). Soll found that the smaller the population of molecules, the more likely it was that not only deleterious mutations but also advantageous mutations would disappear. Why would population size influence the survival of both types of mutations (deleterious and advantageous) in populations
Answer:
Sampling error may allow fixation of one form and the elimination of others in a small population.
Explanation:
It can be seen that in case of a small population size, there are high chances of the elimination or the fixation of the allele in the population when compared to the large population size. Also sampling errors are found in case of small population size that leads to the enhancement of the chances for fixation and also for the elimination of the allele. This large size population doe not have much effect. The random fixation of the either selective allele or the elimination of the disadvantageous allele occurs due to the genetic drift.
SO in order for the population size influenced the survival of both types of mutations , the sampling error may be allowed for the fixation of one of the form and the elimination of the other forms in the small population size.
