Answer:
integrinas y lamininas
Explanation:
Las integrinas son glucoproteínas implicadas en el anclaje de las células epiteliales a la matriz extracelular. Las células epiteliales tienen en su base proteínas integrinas que se unen a otras proteínas tales como vitronectina, fibronectina, colágeno y laminina. De este modo, las integrinas se asocian con lamininas de la lámina basal. Las lamininas son otra clase de glucoproteínas las cuales conforman la lámina basal y contienen sitios de unión para integrinas. A partir de esta asociación las células epiteliales pueden adherirse a la membrana basal y mantener su orientación dentro de un tejido. Estas uniones son fundamentales para que las células epiteliales puedan soportar fuerzas y son críticas durante el desarrollo apropiado (ontogenia) del organismo.
Describe how the lizard population is changing
Answer:
Each time lizards colonized an island, they evolved into many of the same forms. .Other lizards adapted to life among the thin branches lower down on the trees, evolving short legs that help them hug their narrow perches. Still other lizards adapted to living in grass and shrubs, evolving long tails and slender trunks.Lizards are low on the food chain. Providing protection from their natural predators ensures their continued existence. Plant bushy perennials, create a rock or brush pile or use man-made items like stacks of bricks or pipes.

What are the two main components of the cell cycle
In eukaryotic cells or cells with a nucleus, the stages of the cell cycle are divided into two major phases: interphase and the mitotic (M) phase.
What is cell cycle?
The cell cycle, or cell-division cycle, is the series of events that take place in a cell that cause it to divide into two daughter cells. These events include the duplication of its DNA (DNA replication) and some of its organelles, and subsequently the partitioning of its cytoplasm and other components into two daughter cells in a process called cell division.
In cells with nuclei (eukaryotes, i.e., animal, plant, fungal, and protist cells), the cell cycle is divided into two main stages: interphase and the mitotic (M) phase (including mitosis and cytokinesis). During interphase, the cell grows, accumulating nutrients needed for mitosis, and replicates its DNA and some of its organelles. During the mitotic phase, the replicated chromosomes, organelles, and cytoplasm separate into two new daughter cells. To ensure the proper replication of cellular components and division, there are control mechanisms known as cell cycle checkpoints after each of the key steps of the cycle that determine if the cell can progress to the next phase.
In cells without nuclei (prokaryotes, i.e., bacteria and archaea), the cell cycle is divided into the B, C, and D periods. The B period extends from the end of cell division to the beginning of DNA replication. DNA replication occurs during the C period. The D period refers to the stage between the end of DNA replication and the splitting of the bacterial cell into two daughter cells.

What effect do biological washing powders have on the skin?
Answer:
Biological washing powder and liquids contain enzymes. These help to break down fat, grease and proteins to get clothes clean. While enzymes are great for getting rid of stains, they can damage wool, silk and other materials. Many people also find that they aggravate eczema and other sensitive skin conditions.
Explanation:
Answer:
The hysteria surrounding biological detergents in the UK led to claims that it can lead to or exacerbate such conditions as “erythema, pruritus and eczema.” Despite this, the review finds no evidence of any harmful effects to skin from bio washing powders and detergents
Imagine carefully weighing a metal can, leaving it out in the rain for weeks and weeks until it was very rusted, and then carefully weighing it again. Would the can be heavier or lighter after it was rusted?
Answer:
The answer would be heavier, though it depends upon the type of metal. Rusting is essentially corrosion. Rust is often caused by a piece of metal getting soaked in water and then being exposed to oxygen. The rust will add more weight to the can so it becomes heavier.
Leaving out metal can in the rain for weeks and weeks until it was very rusted, and then if we carefully weighing it again it can be found that the can weighs more because the rust deposited on the metal can adds more weight.
What is rust?
Rust is referred to as an iron oxide, and a form of corrosion which is caused by a chemical reaction which affects masses of iron and steel.
Once formed, rust starts to eat away at the metal, forming a flaky, orange red coating which weakens the iron. It occurs when the metal reacts with oxygen and water.

Which graph represents selection that may lead to reduced variation
in a population?
The frequency graph represents selection that may lead to reduced variation in a population.
Identify the statement that describes the imperfection of natural selection. Identify the statement that describes the imperfection of natural selection. Natural selection has not had sufficient time to create the optimal design in each case but will do so given enough time. Natural selection is generally limited to modifying structures that were present in previous generations and in previous species. In many cases, phenotype is not merely determined by genotype but by the environment as well. Though we may not consider the fit between the current skeletal arrangements and their functions excellent, we should not doubt that natural selection ultimately produces the best design.
Answer:
Variability was seen as imperfection, so natural selection could only eliminate the inferior and imperfect, not giving rise to new things, new species.

Mendel crossed yellow-seeded and green-seeded pea plants and then allowed the offspring to self-pollinate to produce an F2 generation. The results were as follows: 6,022 yellow and 2,001 green (8,023 total). Which of the following statements correctly describes the relationship of the allele for green soods to the allele for yellow seeds? A. The green allele is dominant to the yellow allele B. The two alleles exhibit incomplete dominance C. The green alicle is recessive to the yellow allele D. The two alleles are codominant
Answer:
C. The green allele is recessive to the yellow allele
Explanation:
Complete dominance occurs when one gene variant or allele referred to as the 'dominant allele' completely masks the expression of another allele referred to as the 'recessive allele' in heterozygous individuals, i.e., in individuals carrying one copy of the dominant allele and one copy of the recessive allele for a particular locus/gene (whereas homo-zygous individuals carry the same alleles for a given locus/gene). Mendel crossed pure lines of pea plants, i.e., homo-zygous lines for different traits such as seed color (yellow and green) and seed shape (round and wrinkled). In this case, the parental cross was YY x yy, where the 'Y' allele is dominant and encodes for yellow seed color, and the 'y' allele is recessive and encodes for green seed color. From this cross, Mendel obtained a hybrid F1 (i.e., all progeny was heterozygous with genotype Yy). An expected 3:1 ratio as observed in this case (6,022 yellow and 2,001 green seed >> 3:1 ratio) is characteristic of the progeny that results from mating between F1 heterozygous parents, where each parent has one dominant allele and one recessive allele, i.e., F1 parental cross: Yy x Yy >> F2: 1/4 YY (yellow color); 1/2 Yy (yellow color); 1/4 (green color) >> 3:1 ratio of yellow to green seeds.

Which of the following describes the relationship between genes and
chromosomes?
Chromosomes form into genes during cellular reproduction
Genes are special sequences of nucleic acids found on chromosomes
Every gene an organism has is found on every one of its chromosomes
All of an organism's chromosomes can be found next to its genes in the cell nucleus
Answer:
Genes are special sequences of nucleic acids found on chromosomes.
Explanation:
A single DNA molecule is a chromosome. A gene is a certain chromosome region of DNA.
All cells of the body are genetically the same, but cells are different from others because specific gene sets are expressed. Different cells, therefore express different genes, which enable them to perform a specific function.
The deoxyribonucleic (DNA) genes are segments that contain a code for a certain protein that works in one or several cell types in the body. Chromosomes are cellular structures that contain the genes of a person. Genes that are in the cellular nucleus are contained in chromosomes.
Athletes require energy to move their body. What biomolecules directly supplies your muscles with quick energy, or ATP, when broken down?
Creatine phosphate directly supplies muscles with quick energy, or ATP, when broken down.
Creatine phosphate is a phosphorylated creatine molecule. Muscles use stored chemical energy from the food we eat and convert it to heat and kinetic energy. Adenosine triphosphate is the source of energy used to power the movement of contraction in working muscles. However, ATP is not stored in large amounts in cells. So once muscle contraction begins, the process of making more ATP starts quickly. The muscle has three biochemical systems to produce more ATP for muscle contraction. One such biochemical system utilizes creatine phosphate. Muscles have a little ATP in them that they can use immediately but it does not last long. So, all muscle cells have a high-energy compound called creatinine phosphate which is broken down to form ATP quickly.
