Answer:
cotton
Explanation:
Cotton crop leaves soil with the lowest levels of nitrogen.
What is a nitrogen?Nitrogen is the chemical element with the symbol N and atomic number 7. Nitrogen is a nonmetal and the lightest member of group 15 of the periodic table, often called the pnictogens. It is a common element in the universe, estimated at seventh in total abundance in the Milky Way and the Solar System.
Nitrogen is important to the chemical industry. It is used to make fertilizers, nitric acid, nylon, dyes and explosives. To make these products, nitrogen must first be reacted with hydrogen to produce ammonia. This is done by the Haber process.
Nitrogen is important to all living things, including us. It plays a key role in plant growth: too little nitrogen and plants cannot thrive, leading to low crop yields; but too much nitrogen can be toxic to plants [1]. Nitrogen is necessary for our food supply, but excess nitrogen can harm the environment.

how does shell color work to protect the egg from sunlight?
Answer:
Birds that live in cool climates lay darker eggs, as darker colors absorb more heat from the sunlight
Birds that live in hotter climates lay lighter eggs to prevent the egg from overheating.
The pigmentation acts to thermo-regulate the internal temperature of the egg, acting as a buffer between the embryo and the outside world. It does this by preventing overheating of the egg, through reflecting the sunlight off the pigmentation, rather than allowing it to be absorbed through the shell
The type of RNA that delivers amino acids to the ribosome during protein synthesis is tRNA.a) trueb) false
Answer:
A). True
Explanation:
tRNA, which means transfer RNA is one of the three types of RNA known in nature. The tRNA is found in the ribosome, where it plays a pivotal role in protein synthesis (translation). Transfer RNA is the RNA responsible for reading the nucleotides in the mRNA codon and carrying the amino acid that corresponds those codons to the ribosome.
The tRNA has a 3-dimensional structure that allows it to carry anticodon that reads codon and also carry amino acids on opposite ends. Hence, according to this question, tRNA is a type of RNA that delivers amino acids to the ribosome during protein synthesis.

a. Percent similarity of nucleotides will be identical to percent similarity of protein.
b. Percent similarity of nucleotides will be less than percent similarity of protein.
c. Percent similarity of nucleotides will be greater than percent similarity of protein.
Answer:
a. Percent similarity of nucleotides will be identical to percent similarity of protein.
Explanation:
In accordance to the central dogma of biology, PROTEINS are formed from the instructions contained in the nucleotide sequences of GENES. In other words, genes contain nucleotide sequences that holds information needed to produce proteins. This means that every protein is encoded by the nucleotides of a gene.
According to this question, nucleotide sequences of GAPDH will undergo gene expression to form protein sequences of GAPDH. Since GAPDH nucleotide sequences form GAPDH protein sequences, the percent similarity of nucleotides will be identical to percent similarity of protein.

List all six stages of the sensory pathway when an animal responds to information about its environment.
Explanation:
There basically four stages of sensory pathway when an animal responds to information about its environment.
and these stages of pathway are Reception, transduction, transmission, and perception.
The sensory receptors are commonly described as specialised neurons found in sense organs that helps detect and respond to stimuli. The six stages of the sensory pathway which an animal responds to information about its environment are:
Reception: This falla under sensation. It is simply a type of sensory receptors detect that stimulus is present.Transduction: This also falls under sensation. It is a type of sensory receptors whose work is mainly to convert stimulus energy into electrochemical energy.Transmission: This falls under sensation. It is when neural impulses leave sensory organs and moves to the brain.selection: This falls under perception. It acts as detectors that filter the stimuli by responding to particular features of a stimulus while also ignoring the rest.Organisation: This falls under perception: It is known to organise the characteristics of sensory stimuli in a meaningful manner. Interpretation: This Fall also under perception. It is known to give meaning to sensory stimuli.Sensation is simply regarded as a physiological process that uses sensory receptors in detecting and responding to stimuli.
Perception is referred to as the mental work of organising and interpreting sensory stimuli, making it meaningful.

Which step is missing?
A. DNA unzips after step 1.
B. DNA unzips before step 1.
C. DNA is replicated after step 3.
D. DNA is replicated before step 3.
Answer:
B. DNA unzips before step 1.
Explanation:
This question is describing the process of gene expression, which is made up of two major stages namely; transcription and translation. Transcription is the process by which mRNA is synthesized from a DNA template while translation is the process where protein (amino acid sequence) is produced using the mRNA transcript.
This stages of gene expression has been summarized in the steps listed by Shura. However, prior to the formation of an mRNA molecule in step 1, the double stranded DNA has to unwind i.e. separate into single strands as initiated by the enzyme RNA polymerase. Therefore, the list should read as follows:
- DNA unzips
- A strand of RNA is made.
- RNA leaves the nucleus.
- RNA moves to the ribosome.
- A protein is made.

Which of the following is true about temperate forests?
They receive little rain throughout the year.
The temperate forest experiences seasonal changes.
The temperate deciduous forest has cold summers and warm winters.
They are barren and have few trees.
Answer:
Temperate forests typically have winters that often reach below freezing, however even this is not always true. The East Coast forests retain their deciduous nature largely due to the excessive freezing days each winter, as the leaves often freeze over and are only designed to live for one season.
The true statement about temperate forests is : The temperate forest experiences seasonal changes ( B )
The temperate forest regions experiences a high level of rainfall and humidity, it is characterized with a variety of trees ( deciduous ) whom shed their leaves during winter due to the decrease in rainfall and sunlight during winter season.
The shedding of leaves during the winter and the blossom of trees during summer shows that the forest experiences seasonal changes .
Hence we can conclude that the true statement about temperate forest is that the forest experiences seasonal changes.

Metaphase 1 (Homologous chromosomes line up at the center of the cell.)
Anaphase 1 (Homologous pairs separate and move towards opposite ends of the cell)
Telophase 1 (A nuclear membrane forms and cytokinesis follows).
Metaphase 2 ( The haploid number of duplicated chromosomes line up at the metaphase plate.
Anaphase 2 (Sister chromatids separate and become daughter chromosomes that move to the poles)
Meiosis 2: Four haploid daughter cells are formed that are not genetically identical.
Explanation:
Meiosis is a type of cell division that gives rise to gametes ( offsprings). This type of cell division occurs only in the reproductive organs. A diploid cell has two sets of chromosomes: one from the female parent and the other one from the male parent. When the diploid cell undergoes meiosis, the chromosome replicate once and the nucleus and cell duplicate twice giving rise to four haploid gamete cells.
The phases of meiosis occurs in two step divisions. Homologous pairs separate during the first round cell division which occurs in MEIOSIS 1 while the sister chromatids separate in the second nuclear division called MEIOSIS 2.
In each round of division, cells go through four stages: PROPHASE, METAPHASE, ANAPHASE, and TELOPHASE. The specific events that occur in these stages are already listed in the above answer.
Generally, at the start of meiosis, each member of a homologous pair of chromosomes, which are made up of two chromatids, moves to lie side by side. While they are thus paired, genetic material is exchanged between the chromatids. This is known as CROSSING OVER.
When the nucleus divides for the first time, the chromosomes in a given pair( not the chromatids) separate and move to opposite ends of the cell. This results in only half the number of chromosomes going to each daughter cell.
During the second nuclear division, the chromatids separate and move to opposite ends of each daughter cell giving rise to four gamete cells, each with a haploid number of chromosomes.
Meiosis is the process through which haploid gametes are formed from a diploid germ cell. It takes place in two phases of four steps each: prophase, metaphase, anaphase and telophase.
---------------------------------
Through Meiosis, a diploid cell (2n) produces four haploid daughter cells (n).
After DNA replication there are two meiotic phases.
The first one is a reductive phase, in which homologous chromosomes separate.
In the second phase, the cell suffers a new, not reductive division.
1. In the first phase, Meiosis I:
Prophase I: Chromosomes condensate and become visible. Occurs crossing-over between homologous chromosomes. Crossin-over makes the daughter cells to be genetically different from the original one. Metaphase I: Homologous chromosomes randomly align in the equatorial plane. Anaphase I: In this phase occurs the division and independent separation of homologous pairs. Each chromosome migrates to different poles. This separation generates different chromosomal combinations in the daughter cells. Telophase I: Chromosomes of homologous pairs are already in the corresponding poles, and the nuclear membrane forms again in each pole.2. In the second phase, Meiosis II:
Prophase II: Chromosomes condensate again and become visible. Metaphase II: Chromosomes join the spindle apparatus and migrate to the equatorial plane, where they randomly line up. Sister chromatids are holden together until they reach the Anaphase. Anaphase II: Centromeres divide, chromatids get separated, and each of them goes forward an opposite cellular pole. Telophase II: Once in the poles, the chromosomes become lax again, and the nuclear membrane forms again.Cytokinesis occurs at the end of Meiosis II. The final products are four haploid cells different from the original one.
According to this information, the correct order would be as follows
Prophase 1: Homologous chromosomes pair to form a tetrad.Prophase 1: Crossing-over may occur between the non-sister chromatids.Metaphase 1: Homologous chromosomes line up at the center of the cell.
Anaphase 1: Homologous pairs separate and move towards opposite ends of the cell.Telophase 1: A nuclear membrane forms and cytokinesis follows.Metaphase 2: The haploid number of duplicated chromosomes line up at the metaphase plate.
Anaphase 2: Sister chromatids separate and become daughter chromosomes that move to the poles.Meiosis 2: Four haploid daughter cells are formed that are not genetically identical.
