Answer:

Collapse dolines.

Explanation:

A doline is a special type of geological depression characteristic of karst reliefs. These reliefs are formed by the chemical weathering of rocks made of minerals that are soluble in water. In general, dolines are found in places where rocks are composed of limestone and clay in different proportions. When the calcium carbonate of limestone gets in contact with the rainwater, turns into calcium bicarbonate, which is soluble in the presence of water. Clay then deposits in lower areas originating the dolines or depressions.

Dolines might be formed by dissolution (the soil is dissolved in pluvial water that first flood and then infiltrate) or by collapsing. Collapse dolines occur because first, soluble material in lower layers formes a cavity underground. Soluble material flow to lower areas making a place to a cavity or hole under the ground. It gets bigger with time as the material in the bottom keeps being removed. It reaches a point in which the cave can no longer support the roof material, such as rocks, soil, and vegetables, and ends collapsing.

C personalities are organized and controlled. They take their time completing tasks accurately, like to research things thoroughly, and are always prepared.  Because they put so much time and effort into everything they do, they hate to be criticized. They are perfectionists at heart and take even the smallest complaint personally.  This makes them extremely difficult to confront. The best way to approach it is to focus on parts of the problem largely out of the C personality’s control or aspects of the problem they might not have considered.  Make it clear that you appreciate all of their efforts and that you’re bringing something to their attention because it’s a variable that they need to have in the equation in the future. No matter what, don’t frame the conflict as a personal attack. If you do, the C personality will likely become resentful and go out of their way to avoid future interactions with you....!!!!!!

Answer:

because the moon doesn't line up exactly between the sun and the earth every time it passes.

Explanation:

A solar eclipse can only occur when the Moon is close enough to the ecliptic plane during a new moon. ... Total solar eclipses are rare at any particular location because totality exists only along a narrow path on the Earth's surface traced by the Moon's full shadow or umbra. An eclipse is a natural phenomenon.

The cryosphere and the geosphere are two biospheres which destructs the rock.

The cryosphere is the region of the Earth's climate system that contains seasonally frozen ground, solid precipitation, snow, sea ice, lake and river ice, icebergs, glaciers, and ice caps. The name "cryosphere" derives from the Greek word "kryos," which means frost or ice cold.

A non-profit, international scientific magazine called The Cryosphere (TC) is devoted to publishing and discussing research papers, brief communications, and review articles on all facets of frozen ground and water on Earth and other planetary bodies.

Ice sheets and glaciers, planetary ice bodies river and lake ice, seasonal snow cover, sea ice, inner sensing, numerical modeling, in situ and laboratory studies.

Therefore, The cryosphere and the geosphere are two biospheres which erodes the rock.

Answer:

knowledge of the sequence product

Explanation:

A gene knockout is a technique used in molecular genetics to deactivate target genes in an organism in order to study their functions by reverse genetics (i.e., gene loss). Knockouts are generated by different methods including, for example, homologous recombination or site-specific nucleases (zinc-fingers, TALENS, CRISPR/Cas9). These techniques require to know a priori the sequence of each gene to be knocked out in order to target desired mutations. In the last years, the CRISPR/Cas9 tool has gained attention to knockout genes of interest because it is a genome editing system that can be easily used for deletion or insertion of bases.

Answer:

Tortoises with better adaptations in shell shape and leg length were selected to exploit the food resources on each island and, thus, they were capable of having more offspring.

Explanation:

Natural selection can be defined as the process of differential survival and reproduction in a given environment due to differences in their phenotypic traits. Thus, these phenotypic traits are selected to be better adapted to their environment. As a consequence of natural selection, organisms evolve by changing their phenotype frequencies over many generations. In this case, phenotypic differences are expressed as variations in shell shape and leg length, which are adaptive traits that were selected on each island.

Answer: D. Individuals with different adaptations in shell shape and leg length best exploited the food resource and left more surviving offspring in each island.

Cytokinesis is the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells.

Explanation:

Answer:cytoknesis

Explanation:

Answer:

1. The true statement about the relationship between an organism's traits and its genes is that genes encode the proteins that determine an organism's traits (option B).

2. A DNA mutation can cause the structure of the protein to be changed (option C).

Explanation:

DNA contains the genetic information necessary for the structure and function of living beings. It is a molecule that, once transcribed into mRNA, dictates the rules for protein synthesis.

1. Chromosomes are composed of a DNA molecule, whose segments form the genes that contain specific base sequences to determine a trait.

The information from the DNA is transcribed into the mRNA, which is responsible for carrying it to the cytoplasm where protein synthesis occurs. These proteins formed from the genetic code determine the different traits in living beings. So, genes encode the proteins that determine an organism's traits.

2. Since the DNA contains the information needed to transcribe it into the mRNA and for the mRNA to initiate protein synthesis, any alteration in the DNA base sequence -due to mutation- can be produced:

There is a relationship between the DNA mutation and the structure of the protein being changed.
