Q: During asexual reproduction, fungi produce haploid spores by what process involving a haploid parent cell? Read this paragraph and choose the correct option from the provided answers: During asexual reproduction, fungi produce haploid spores by mitosis of a haploid parent cell. A haploid cell has just one of each pair of chromosomes. The haploid spores are genetically identical to the parent cell. Spores may be spread by moving water, wind, or other organisms. Wherever the spores land, they will develop into new hyphae only when conditions are suitable for growth. Choices: - osmosis - evaporation - divergence - mitosis A:
mitosis

mollusk

Ques: Q: What increases the size of a population's gene pool? Read this paragraph and choose the correct option from the provided answers: A gene pool is the complete set of unique alleles in a species or population. Mutations create variation in the gene pool. Populations with a large gene pool are said to be genetically diverse and very robust. They are able to survive intense times of natural selection against certain phenotypes. During these times of selection, individuals with less favorable phenotypes resulting from deleterious alleles (due to mutations) may be selected against and removed from the population. Concurrently, the more favorable mutations that cause beneficial or advantageous phenotypes tend to accumulate in that population, resulting, over time, in evolution. In fact, without any change in the gene pool, without any new alleles added due to new mutations, evolution could not occur. Genetic change is the driving force of evolution. In fact, evolution can be genetically defined as the change allele frequencies over time. Choices: - mass extinction - microbes - natural selection - mutations A:
Ans: mutations

Ques:Q: The genome of an organism consists of one or more what? Read this paragraph and choose the correct option from the provided answers: Copying and passing on genes (genetics) In which we consider the dynamics of genes and gene expression, and how genome dynamics leads to families of genes and facilitates evolutionary change. We consider how DNA is organized within a cell and how its organization influences gene expression. Finally we consider the behavior of regulatory networks at the molecular level and the role of molecular level noise in producing interesting behaviors. At this point we have introduced genes, DNA, and proteins, but we have left unresolved a number of important questions. These include how genomes are organized, how they evolve, how new genes and alleles are generated, and how they work together to produce the various behaviors that organisms display.327 We will touch on such trendy topics such as epigenetics (which is probably less interesting than most suppose) and the rather complex molecular and cellular level processes behind even the simplest biological behaviors. The details, where knownand often they are notare beyond the scope of this course, but the basic themes are relatively straightforward, although it does takes some practice to master this type of thinking. The key is to keep calm and analyze on! Genomes and their organization Genomes are characterized by two complementary metrics, the number of base pairs of DNA and the number of genes present within this DNA. The number of base pairs is easier to measure, we can count them. This can, however, lead to a mistaken conclusion, namely that the number of base pairs of DNA within the genome of a particular species, organism, or even tissue within an organism is fixed and constant. In fact genomes are dynamic, something that we will return to shortly. The genome of an organism (and generally the cells of which it is composed) consists of one or more DNA molecules. When we talk about genome size we are talking about the total number of base pairs present in all of these DNA molecules added together. The organism with one of the largest known genomes is the plant... Choices: - hemoglobin molecules - require molecules - rna molecules - dna molecules A:

Ans:dna molecules

Q: The first few species to colonize a disturbed area are called what? Read this paragraph and choose the correct option from the provided answers: The first few species to colonize a disturbed area are called pioneer species. In primary succession, pioneer species must be organisms that can live on bare rock. They usually include bacteria and lichens (see Figure below ). Along with wind and water, the pioneer species help weather the rock and form soil. Once soil begins to form, plants can move in. The first plants are usually grasses and other small plants that can grow in thin, poor soil. As more plants grow and die, organic matter is added to the soil. This improves the soil and helps it hold water. The improved soil allows shrubs and trees to move into the area. Choices: - producer species - original species - colonization species - pioneer species A:
pioneer species
