Option D. Minerals in the rock stretched under the pressure of Earth's moving plates.

Gneiss is a metamorphic rock that forms from the transformation of pre-existing rocks under high temperature and pressure conditions. It is characterized by its banded appearance, with alternating light and dark layers. These bands, known as foliation, are a result of the mineral grains in the rock being stretched and aligned in parallel orientations.

The formation of gneiss typically occurs during regional metamorphism, where rocks are subjected to intense pressure and heat over large areas. As tectonic plates collide or undergo significant deformation, immense pressure is exerted on the rocks. This pressure causes the minerals within the rock to recrystallize and reorganize, resulting in the alignment of mineral grains along planes of foliation.

The alternating light and dark bands in gneiss are primarily due to variations in mineral composition. Light-colored bands usually consist of minerals such as quartz and feldspar, while dark bands often contain minerals like biotite or amphibole. The differential pressure during metamorphism can cause these minerals to segregate into distinct layers, creating the banded appearance.

In summary, the bands in gneiss form as a result of the minerals in the rock stretching and aligning under the pressure exerted by Earth's moving plates during regional metamorphism. This process leads to the distinctive banded texture observed in gneiss. Therefore the correct option is D

The possible cause of Emily's dying crops, indicated by white spots and cracked ground, could be salinization.

Salinization refers to the accumulation of salt in the soil, which can have detrimental effects on plant growth and health. When the soil becomes salinized, it means that the salt concentration in the soil is too high for plants to tolerate. The white spots observed on the ground could be salt deposits left behind as the water evaporates, indicating the presence of excessive salt.

Salt accumulation in the soil can occur due to various factors, such as irrigation practices with high-salt water or poor drainage that leads to the accumulation of salts from groundwater. As the salt concentration increases, it creates an osmotic imbalance that affects the ability of plants to take up water, leading to dehydration and wilting. Additionally, high salt levels can directly damage plant tissues and interfere with essential physiological processes.

If Emily's crops are experiencing wilting, white spots, and cracked ground, it suggests that salinization is a likely cause. Proper soil management practices, such as improving drainage, leaching salts, and using appropriate irrigation methods, can help mitigate salinization and restore the health of the crops.

The homologous chromosome pairs, also known as bivalents or tetrads, line up along the metaphase plate in a random order during metaphase I of meiosis I.

They are known as homologous pairs of chromosomes. When homologous chromosomes line up next to one another during meiosis, they create a tetrad. Two homologous chromosomes make into a tetrad, which has four sister chromatids altogether and is held together by a feature known as the chiasmata. When two homologous chromosomes that have already duplicated their DNA link up, they form a tetrad. The main distinction is that a tetrad consists of two homologous chromosomes that resemble an X rather than an I. A pair of two chromosomes, usually one from the mother and one from the father.

Answer:

I believe 1 and 4 are prokaryotic.

Explanation:

Antisense sequence of the given segment of DNA is 3'-TAC TAT CGG CTA CCG ACT AGG TAC-5'.The DNA strand complementary to a given DNA strand is known as antisense strand. For the given sequence, the antisense sequence will be formed by replacing each nitrogen base with its complementary base that is:T-A, A-T, C-G, and G-C.

The corresponding mRNA codon sequence for the sense strand of a segment of DNA is5'-AUG AUA GCC GAU GGC UGA UCC AUG-3'.In order to transcribe DNA into mRNA, the DNA double helix should be separated first, then using RNA polymerase an mRNA molecule will be produced. RNA polymerase starts transcribing the mRNA molecule from the 3' end towards the 5' end.

Therefore, mRNA sequence will be complementary to the template DNA sequence i.e., replacing each base of DNA with its corresponding RNA base that is: T-A, A-U, C-G, and G-C. C) There are three tRNA sequences that correspond to the mRNA codon sequence:AUG, AUA, GCC, GAU, GGC, UGA, UCC, AUG which are as follows:1st tRNA anticodon sequence will be 3'-UAC-5' which corresponds to the codon AUG.2nd tRNA anticodon sequence will be 3'-AUA-5' which corresponds to the codon AUA.3rd tRNA anticodon sequence will be 3'-CGG-5' which corresponds to the codon GCC.4th tRNA anticodon sequence will be 3'-CUA-5' which corresponds to the codon GAU.5th tRNA anticodon sequence will be 3'-GCC-5' which corresponds to the codon GGC.6th tRNA anticodon sequence will be 3'-AGG-5' which corresponds to the codon UGA.7th tRNA anticodon sequence will be 3'-AGG-5' which corresponds to the codon UCC.8th tRNA anticodon sequence will be 3'-UAC-5' which corresponds to the codon AUG.

The key finding that enabled Meselson and Stahl to settle on ONE hypothesis was that the DNA replication process is semi-conservative.

Their experiment involved growing bacteria in a medium containing heavy nitrogen and then switching them to a medium with light nitrogen. By analyzing the density of the DNA using centrifugation, they found that the new DNA contained both heavy and light nitrogen, indicating that each strand of the original DNA served as a template for the synthesis of a new complementary strand. This finding supported the semi-conservative hypothesis of DNA replication, it is the process through which cells make copies of the genome's DNA. A cell must first copy (or duplicate) its entire genome before it can divide, ensuring that each daughter cell has a complete genome upon division.
