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.
How are mechanical and chemical weathering similar?
A - Both break down rock
B - Both build up up landforms
C - Both only occur when water is present.
D - Both change the composition of the rock.
Answer: A - Both Break down rock
Explanation: Mechanical weathering preserves composition, weathering doesn't build landforms, and water doesn't need to be present for weathering to occur.
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.

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.

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.
Plants have structures which affect reproduction rates in plants.

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.

The curly toe phenotype is controlled by 4 genes that act in an additive manner. The environment does not have an effect on this trait. A dominant allele (represented by the capital letters) has 6 units of risk. A recessive allele (represented by the lower case letters) has 2 units of risk. Individuals with more than 35 units of risk have curly toes. Individuals with 35 or fewer risk units have straight toes.
What is the highest number of risk units an individual can have with this model?

What is the phenotype of an individual of genotype AaBbCCDd? .
Curly Toes Straight Toes notype AAbbCcDd is married to an individual of genotype AaBbCCDd.
Is it possible for them to have a child with curly toes?
Answer:
What is the highest number of risk units an individual can have with this model? 48 units of riskWhat is the phenotype of an individual of genotype AaBbCCDd? The individual has curly toesIs it possible for them to have a child with curly toes?Yes, the couple can have children with curly toes.
Explanation:
Available data:
The curly toe phenotype is controlled by 4 diallelic additive genesGenes A, B, C, D A dominant allele has 6 units of riskA recessive allele has 2 units of riskIndividuals with more than 35 units of risk have curly toesIndividuals with 35 or fewer risk units have straight toesThe term quantitative heritability refers to the transmission of a phenotypic trait in which expression depends on the additive effect of a series of genes.
Polygenic heritability occurs when a trait results from the interaction of more than one gene. And these genes can also have more than two alleles. The action of many genes and alleles can cause many different combinations that are the reason for genotypic graduation.
Quantitative traits are those that can be measure, such as longitude, weight, eggs laid per female, among others. These characters do not group individuals by any precise and clear categories. Instead, they group individuals in many different categories that depend on how the genes were intercrossed and distributed during meiosis. The result depends on the magnitude in which each allele contributes to the final phenotype and genotype. When they interact, they create a gradation in phenotypes, according to the level of contribution.
According to this information, and knowing how each allele contributes to the risk, we can say that the minimum units of risk are 16, determined by the recessive genotype aabbccdd. Each recessive allele contributes with 2 units of risk, so (aa=4units + bb=4 units + cc=4 units + dd=4 units) = 16 units.
Each time a dominant allele is present in the genotype, it adds 6 units to the total risk.
What is the highest number of risk units an individual can have with this model?
48 units of risk, which corresponds to the genotype AABBCCDD. Each dominant allele contributes 6 units to the risk. There are 8 dominant alleles, so, 8x6=48 units.
What is the phenotype of an individual of genotype AaBbCCDd?
The individual has curly toes because it has a risk of 36 units, which is superior to the limit of 35 units. Dominant alleles A, B, C, C, D contribute with 30 units of risk (6x5), and recessive alleles a, b, d contribute 6 units of risk (3x2).

F1) 16 /32 = 1/2 individuals in the progeny are expected to have curly toes
16 /32 = 1/2 individuals are expected to have straight toes
Is it possible for them to have a child with curly toes?
Yes, the couple can have children with curly toes.
To have curly toes, individuals must have more than 35 units of risk.
To have more than 35 units, individuals´ genotypes must carry at least 5 dominant alleles (which equal 30 units).

Four stage in which abortion cannot be done.
Answer:
Fourth trimester.
Explanation:
Fourth trimester is the fourth stage in which abortion can not be done because the baby is big enough in size and comes out from the womb. The abortion in this stage can put the life of the mother in danger so that's why abortion is not allowed. Newborn babies are learning to adjust itself to life outside the womb where it was warm so we can say that fourth trimester is the stage in which abortion is risky and dangerous.
