No increase in diversity:
One extreme trait is favored:
Diversity decreases:
Diversity increases:
Answer:
Results in the evolution of the species: Directional selection
Results in new species: Disruptive selection
Favors traits at the two extremes: Disruptive selection
No increase in diversity: Directional selection
One extreme trait is favored: Directional selection
Diversity decreases: Stabilizing selection
Diversity increases: Disruptive selection
Explanation:
Directional selection which is also known as positive selection is known to be a mode of natural selection. In this type of selection, an extreme phenotype is favored over other phenotypes. This makes the allele frequency to move in the direction of that phenotype and this takes place over time.
Disruptive selection (known to be diversifying selection) talks about the certain changes in the population genetics whereby extreme values of a particular trait are favored over intermediate values. This results in new species.
While Stabilizing selection is a natural selection whereby there is a stabilization of the population mean on the particular value of a non-extreme trait. Here the diversity is decreases.
Answer: A) directional selection
B) disruptive selection
B) disruptive selection
A) directional selection
A) directional selection
C) stabilizing selection

What about DNA’s structure /shape makes it the perfect molecule for heredity and genetics?
Heredity, Genes, and DNA
Perhaps the most fundamental property of all living things is the ability to reproduce. All organisms inherit the genetic information specifying their structure and function from their parents. Likewise, all cells arise from preexisting cells, so the genetic material must be replicated and passed from parent to progeny cell at each cell division. How genetic information is replicated and transmitted from cell to cell and organism to organism thus represents a question that is central to all of biology. Consequently, elucidation of the mechanisms of genetic transmission and identification of the genetic material as DNA were discoveries that formed the foundation of our current understanding of biology at the molecular level.
Genes and Chromosomes
The classical principles of genetics were deduced by Gregor Mendel in 1865, on the basis of the results of breeding experiments with peas. Mendel studied the inheritance of a number of well-defined traits, such as seed color, and was able to deduce general rules for their transmission. In all cases, he could correctly interpret the observed patterns of inheritance by assuming that each trait is determined by a pair of inherited factors, which are now called genes. One gene copy (called an allele) specifying each trait is inherited from each parent. For example, breeding two strains of peas—one having yellow seeds, and the other green seeds—yields the following results (Figure 3.1). The parental strains each have two identical copies of the gene specifying yellow (Y) or green (y) seeds, respectively. The progeny plants are therefore hybrids, having inherited one gene for yellow seeds (Y) and one for green seeds (y). All these progeny plants (the first filial, or F1, generation) have yellow seeds, so yellow (Y) is said to be dominant and green (y) recessive. The genotype (genetic composition) of the F1 peas is thus Yy, and their phenotype (physical appearance) is yellow. If one F1 offspring is bred with another, giving rise to F2 progeny, the genes for yellow and green seeds segregate in a characteristic manner such that the ratio between F2 plants with yellow seeds and those with green seeds is 3:1.

Which is the smallest unit of life in living organism?
cell
The cell is the smallest structural and functional unit of living organisms, which can exist on its own. Therefore, it is sometimes called the building block of life. Some organisms, such as bacteria or yeast, are unicellular—consisting only of a single cell—while others, for instance, mammalians, are multicellular.

Como ha llevado la evolucion a que este insecto phyllium giganteumparezca una hoja segun la teoria de lamarck
Answer:
Due to adaptation of the environment.
Explanation:
Evolution has led this insect phyllium giganteum to appear like a leaf according to Lamarck's theory because this insect lives and feed on the leaf environment so in order to save itself from other predators it takes the shape and structure of leave in order to hide itself so this adaptation slowly transmitted from the parents to the offspring and as a result evolution occurs.

What’s the different properties of hbA and HbS
Answer:
The isoelectric point of normal HbA is 6.9 [91], but HbS has two fewer negative charges per hemoglobin molecule than HbA because glutamic acid residues in the β-chains of HbS were substituted by the valine residues [5], [6]. It shows that HbS has more hydrophobicity than HbA in this condition [10]

Why don't offspring always look like their parents?
A. The way offspring look also depends on their behavior traits.
B. The way offspring look also depends on the amount of nutrients received during birth.
C. The way offspring look depends on the combinations of alleles they inherit and on interactions between traits and the environment.
D. The way offspring look depends on the combinations of alleles they inherit and on interactions between genes and the environment.
Answer: The answer is C. The way offspring look depends on the combinations of alleles they inherit and on interactions between traits and the environment.
Explanation: Each baby isn't an exact clone of the parents. They share different alleles from different parents. Think about it. If the dad and mother didn't look alike then how could the baby have the same physical features as both combined. So basically, The way offspring look depends on the combinations of alleles they inherit from their parents.

B
increased exposure to the rising levels of atmospheric CO2
с
increased exposure to bacteria in drinking water
D
increased exposure to X-rays
Answer:
Increased exposure to X-rays
Explanation:
X-rays shoot harmful radiation through your body, that's why when you go to the dentist or other places and they take a X-ray they give you a lead vest to protect your organs from unneeded radiation.
hope this helps :)
Increased exposure to X-rays is the most likely cause of an increase in the frequency of genetic mutations in humans (Option D).
A mutation is any alteration in the nucleotide (DNA) sequence of the genome in the cells of an organism.Mutation can be caused by physical factors (e.g., X-rays) or chemical agents (e.g., pesticides such as DDT).X-rays are well known to cause mutations by breaking covalent bonds in DNA, which may be erroneously repaired, thereby leading to deletions of nucleotides.In conclusion, increased exposure to X-rays is the most likely cause of an increase in the frequency of genetic mutations in humans (Option D).
