What was the result of using drainage blocks to keep water in the field level during the growing season?

Answers

Answer 1

Answer:

This question is incomplete

Explanation:

This question is incomplete. However, it should be noted that the idea of blocking the drainage, which could cause waterlogging (since the water will not be able to leave the field), is a type of irrigation that ensures there is sufficient amount of water for the plants to grow during a growing season. Although, some plants do not grow well in environments like this (in the case of waterlogging) because this environment lowers oxygen level in the root o the plant (caused by the water at the top of the soil).

If one strand of DNA has the base sequence TTCCGGAA The complementary strand has which of the following sequence?

Answers

Answer:

If a DNA strand has the base sequence TTCCGGAA the complementary strand has the sequence AAGGCCTT.

Explanation:

A DNA molecule is constructed from sequences of its four nitrogenous bases: adenine, thymine, guanine and cytosine. Since DNA is made up of two strands, the sequence of nitrogenous bases of one strand is complementary to the other .

The complementarity of the bases is a characteristic of the nitrogenous bases in the nucleic acids to combine with their complementary base, which is the same as saying that purines complement with pyramidines.

Adenine is combined with Thymine A=T Cytosine is complemented with Guanina C≡G

In this way, given a sequence on a DNA strand :

    T-T-C-C-G-G-A-A

The complementary strand will have this sequence:

    A-A-G-G-C-C-T-T

If a cell in G1 has 20 chromosomes, then at the end of meiosis I there will be _________ chromosomes in each daughter cell, and __________ sister chromatids in each daughter cell.

Answers

Answer:

10 chromosomes

20 chromatids

Explanation:

Meiosis is the process by which sexually reproducing organisms produce gametes for sexual reproduction. Meiosis, which reduces the chromosomal number of the parent cell by half, occurs in two stages namely: meiosis I and meiosis II.

Meiosis I is where the actual reduction in chromosomal number takes place because homologous chromosomes are separated in this stage. For example, a cell in G1 that has 20 chromosomes will have 10 chromosomes in each daughter cell at the end of meiosis I.

Since, DNA replication occurs in the S-phase, sister chromatids are formed for each chromosome. Hence, there would be 20 sister chromatids joined together by a centromere at the end of meiosis I.

This question is incomplete; the complete part is: what are the independent, dependent, and controlled variables?

Independent variable: ORGANIC AND CHEMICAL FERTILIZERS

Dependent variable: HEIGHT OF PLANT

Controlled variable: Same type of seed, water

Explanation:

Independent variable is the variable that is changed or manipulated by the experimenter. In this question, John wanted to test the effects that organic and chemical fertilizers had on plant growth. Hence, the independent variable is the ORGANIC AND CHEMICAL FERTILIZERS used.

Dependent variable is the variable that responds to changes made to the independent variable. The dependent variable is the variable that is measured in an experiment. In this case, the HEIGHT OF PLANTS MEASURED is the dependent variable.

Controlled variable or Constant is the variable that is kept unchanged throughout the experiment in order not to influence the experimental result or outcome. In this case, the controlled variable is the SAME TYPE OF SEED USED, WATER.

Independent Variable: organic + chemical fertilizers
Dependent Variable: height of the plants
Controlled Variable: seed, soil, water

Put the steps in the proper order to explain the flow of information from the DNA sequence to a functional protein.

1. The codon sequence in mRNA determines the amino acid sequence in a polypeptide.
2. Each codon in mRNA codes for a specific amino acid.
3. The sequence of amino acids in a polypeptide determines how the protein will fold and possibly bind with other polypeptides to form a mature protein.
4. The final structure of a protein determines its function.
5. Each three nucleotides in the gene template DNA codes for a three nucleotide codon in mRNA.

Answers

Answer:

5. Each three nucleotides in the gene template DNA codes for a three nucleotide codon in mRNA.

2. Each codon in mRNA codes for a specific amino acid.

1. The codon sequence in mRNA determines the amino acid sequence in a polypeptide.

3. The sequence of amino acids in a polypeptide determines how the protein will fold and possibly bind with other polypeptides to form a mature protein.

4. The final structure of a protein determines its function.

Explanation:

The process of gene expression follows the central dogma of biology I.e. Gene (DNA) --> mRNA ---> Protein. The process of gene forming mRNA is called transcription while the process of mRNA forming protein is called translation.

Based on this, the order of the flow of information from the DNA sequence to a functional protein is:

- Each three nucleotides in the gene template DNA codes for a three nucleotide codon in mRNA (transcription).

- Each codon in mRNA codes for a specific amino acid.

- The codon sequence in mRNA determines the amino acid sequence in a polypeptide (translation).

- The sequence of amino acids in a polypeptide determines how the protein will fold and possibly bind with other polypeptides to form a mature protein.

- The final structure of a proteiin determines its function.

The order is 'three nucleotides in DNA codes for a codon', 'each codon codes an amino acid', 'codon sequence determine amino acid sequence', 'amino acids determine protein folding' and 'final protein structure determines its function'.

During gene transcription, a fragment of DNA referred to as 'gene' is used as a template to create an mRNA, which is then used to synthesize a polypeptide.

The triplets of nucleotides or 'codons' in the mRNA sequence determine the amino acid sequence in the nascent polypeptide chain.

The synthesized protein is then folded in the endoplasmic reticulum (ER) and thus adopts its three-dimensional (3D) conformation.

Protein folding is achieved by specific proteins called chaperones that help to correctly fold the protein, which adopts a mature conformational active state.

In conclusion, the order is 'three nucleotides in DNA codes for a codon', 'each codon codes an amino acid', 'codon sequence determine amino acid sequence', 'amino acids determine protein folding' and 'final protein structure determines its function' (order 52134).

What happens to the actin and myosin during a muscle contraction?

Answers

Answer:

Once the myosin-binding sites are exposed, and if sufficient ATP is present, myosin binds to actin to begin cross-bridge cycling. Then the sarcomere shortens and the muscle contracts. In the absence of calcium, this binding does not occur, so the presence of free calcium is an important regulator of muscle contraction.

Vacunas

Las vacuna son preparaciones seguras obtenidas mediante numerosos ensayos clínicos, cuyo objetivo es generar inmunidad contra una enfermedad mediante la producción de anticuerpos. Basicamente, existen tres tipos de vacunas: vacunas atenuadas, vacunas de ARN mensajero y vacunas de terapia genética. En primer lugar, las vacunas atenuadas están desarrolladas usando fragmentos del virus que provoca la enfermedad, lo cual se conoce como vacunas atenuadas porque están fabricadas con virus atenuados/inactivados. Por otra parte, en los últimos años, han sido desarrolladas vacunas derivadas de ARN mensajeros (ARNm) las cuales permiten sintetizar una proteína específica del virus (antígeno) y de este modo generar una respuesta inmune que permanecerá ante una posible infección. Finalmente, las vacunas de terapia génica utilizan como vector un virus que no se integra al genoma pero que es altamente estable, como por ejemplo un adenovirus (un virus del resfriado común), el cual permite introducir en las células la información genética del patógeno a fin de generar proteínas virales específicas capaces de desencadenar una respuesta inmune, es decir, generar anticuerpos específicos, contra el virus.
