A substace put in a space or cantainer to fill it, usually applied in wood to fill up cracks and grooves
Answer:
Glue and sawdust.
Explanation:
Glue and sawdust are the substances that applied in wood to fill up cracks and grooves. You can use the glue and sawdust method to fill the gaps present in the wood. This method is a quick and easy solution that successfully fill up the gaps and grooves on the wood. The method of using this method is, first fill the gap with a small amount of wood glue, then rub sawdust into the gap which attached the saw dust with itself and the gaps are filled.

An area surrounded by tall mountains contains a very large, isolated population of green and white peacocks. During the mating season, the male peacocks demonstrate flashy feather displays to attract females, who usually choose green peacocks over white ones. A biology student tabulates the following information.
Genotype
Plumage Color % of Population Allele Controlled Phenotype
FF or Ff
Dark green
84%
F (dominant)
Dark green plumage
ff
White
16%
f (recessive)
White plumage
Using this information, the student plans to use the Hardy-Weinberg equation to predict the allele frequencies in future peacock generations. Why would her research advisor have a problem with this? (2 points)
Group of answer choices
The student needs the percent of the population with the Ff genotype in order to find the F frequency.
Her research advisor would first want her to find the males' mating success rate for the calculations.
The peacocks are sexually selective when choosing mates, so future allele frequencies may drift.
Since the peacock population is isolated, its alleles would shift away from Hardy-Weinberg equilibrium.
Answer:
The peacocks are sexually selective when choosing mates, so future allele frequencies may drift.

What does biodiversity mean ?
Answer:
biodiversity mean Biodiversity, also called biological diversity, the variety of life found in a place on Earth or, often, the total variety of life on Earth.
Explanation:
Answer: Biodiversity is a term used to describe the enormous variety of life on Earth. It can be used more specifically to refer to all of the species in one region or ecosystem. Biodiversity refers to every living thing, including plants, bacteria, animals, and humans.
Explanation: Usually three levels of biodiversity are discussed—genetic, species, and ecosystem diversity.
Genetic diversity is all the different genes contained in all individualplants, animals, fungi, and microorganisms. It occurs within a species as
well as between species.
Species diversity is all the differences within and between populationsof species, as well as between different species.
Ecosystem diversity is all the different habitats, biological communities,and ecological processes, as well as variation within individual ecosystems.

A freckled man marries a woman without freckles. They have four children, two with freckles, and two without freckles. What are the genotypes of all these people?
Answer:
The genotype of the father: Ff
The genotype of the mother: ff
The genotype of the two children without freckles: ff
The genotype of the two children with freckles: Ff
Explanation:
Freckles (F) are is dominant trait, so one dominant allele in the genotype of an individual will cause he/she to have freckles. Since the father has freckles, but only two of his children has freckles; that means that he has a heterozygous genotype. In the Punnett Square, the offsprings' genotypes are shown, as well as the parents'.
A freckled man marries a woman without freckles, and they have four children, two with freckles and two without, so the genotype of the parents are Ff, ff and the children with freckles are Ff, while the freckleless are ff types.
What is the significance of the freckle trait?There are both dominant and recessive traits that determine the person's quality, such as freckles, which are dominant over being freckleless. When the parents with freckles cross with the parents without freckles, they will produce half the freckles and half the freckleless. The parent with a freckle is heterozygous (Ff), so two types of gametes will be produced, such as F and f, and will form Ff and ff offspring when crossed with the freckleless parent (ff).
Hence, a freckled man marries a woman without freckles, and they have four children, two with freckles and two without, so the genotype of the parents are Ff, ff and the children with freckles are Ff, while the freckleless are ff types.

Many research studies have shown that different species may possess some of the exact same genes but show vastly different traits. How can that happen?
Answer:
Mutation can occur or the order in which these genes appear are in different order. Genetic variation can also occur.

What is the phenotypic ratio of the F2 generation?
Answer:
9:7
Explanation:
We get the dominant phenotype in plants that have at least one dominant allele of EACH of the two genes; otherwise we get the recessive phenotype. So, the observed ratio in the F2 generation is 9:7.

Protein in your diet provide what necessary substances to repair muscles?
The muscle damage initiates a repair process in which certain hormones, along with the macronutrient protein, synthesize new satellite cells, which are used to repair the damaged muscle fibers. In other words, the role of protein is to help repair tissues damaged by exercise.

distinguish between absorption and reabsorption in the mammalian body
Answer:
Tubular reabsorption is the process that moves solutes and water out of the filtrate and back into your bloodstream. This process is known as reabsorption, because this is the second time they have been absorbed; the first time being when they were absorbed into the bloodstream from the digestive tract after a meal.

Explanation:
Darwin's Theory of Evolution by Natural Selection
More individuals are produced each generation that can survive. Phenotypic variation exists among individuals and the variation is heritable. Those individuals with heritable traits better suited to the environment will survive.Charles Darwin's theory of evolution states that evolution happens by natural selection. Individuals in a species show variation in physical characteristics. ... As a consequence those individuals most suited to their environment survive and, given enough time, the species will gradually evolve.
