Answer:
Temperature and light
Explanation:
This two factors are determinants in terrestrial biomes, because the temperature is closely related to rainfall, to the formation of glaciers, to the migration of species. And the light is related from the use of these reay by the plant, through the greenhouse effect. This two make the biodiversity to be what it are
A haploid cell is a cell typically with half the number of chromosomes (a sex cell) used for reproduction.
A diploid cell is the opposite, a full set of chromosomes not intended for sexual reproduction but typically used in mitosis.
Answer;
-Variety
Ethan is not achieving the variety principle
Explanation;
-Eating a variety of foods and choosing the appropriate number of servings from the food guide pyramid is something that many people do not do.
-No two food items provide the exact same nutrients and this is why it is important to eat an assortment of foods. This means that some food items are better sources for nutrients than other items and vise versa.
-Balance and moderation are also important aspects of daily intake of food. Balance compares with variety because of the importance of eating a balanced diet from the Food Pyramid. Also balance is associated with caloric intake/expenditure.When equality is found between food intake (calories taken in to the body) and physical exercise (caloric expenditure) a maintaining of body weight occurs.
Moderation involves controlling or regulation of food intake.
Answer:
Regarding the genotype and phenotype of the original parents they are known by the name of parental classes. These parental classes have appeared of the genotype are classified as homozygous or heterozygous.
Explanation:
While the reciprocal classes are also the genotypes and phenotypes of the crosses. These reciprocal classes are personified if the crossing occurs between the homozygous alleles. This is due to the fact that the chromosomal part is exchanged in the two chromosomes, since the cross products are the same as the products that are formed in the parent classes, this occurs in a phenomenon known as homozygosity.
In the event that the crossover occurs in a heterozygous allelic tetrad, then an exchange between the different chromosomal parts will occur, resulting in recombinant alleles. In this particular case, the parenting classes cannot be the same. This phenomenon is known as heterozygosity.
Answer:
Mendel's Laws are a set of basic rules on the inheritance of characteristics from parent organisms to their children. They are considered rules rather than laws, since they are not fulfilled in all cases. Mendel's first Law of equitable segregation establishes that during the formation of the gametes each allele of a pair is separated from the other member to determine the genetic constitution of the filial gamete, the two alleles, which code for each characteristic, are segregated during the production of gametes through meiotic cell division. This means that each gamete will contain only one allele for each gene. This allows the maternal and paternal alleles to combine in the offspring, ensuring genetic variation. For each characteristic, an organism inherits two alleles, one for each relative. This means that in somatic cells, one allele comes from the mother and one from the father.
Explanation:
Mendel's laws reflect chromosomal behavior during meiosis: the first law responds to the random migration of homologous chromosomes to opposite poles during anaphase I of meiosis (both alleles and homologous chromosomes segregate equally or 1: 1 in gametes) and the second law, to the random alignment of each pair of homologous chromosomes during metaphase I of meiosis (whereby different genes and different pairs of homologous chromosomes segregate independently).Even though not all genes are inherited in the proportions described by Mendel, they are undoubtedly all inherited in the same way, that is, the alleles or different alternatives of a gene are separated in meiosis and each gamete will carry only 1 of them (2nd Mendel's Law) and in turn all genes on different pairs of chromosomes are transmitted independently. This allows the maternal and paternal alleles to combine in the offspring, ensuring genetic variation.Therefore, of each possible genotype for a two three or more genotypes it is possible to know how many gametes it will form, in what proportions and therefore predict results of crosses.
