It refers to the processes of meiosis and fertilization.
It involves only some of the seedless vascular plants.

Answer:

this mutation may change the open reading frame of the resulting RNA sequence and its final product, which is a protein in the case that this gene is used to synthesize a messenger RNA (mRNA) sequence

Explanation:

During the transcription, a region of DNA named 'gene' is used as template to produce an RNA molecule, typically a primary transcript of mRNA (pre-mRNA). Subsequently, this pre-mRNA suffers a process named RNA processing in order to generate a mature mRNA which is finally used to create a protein by a process called translation. If a deletion occurs during transcription, it may change the open reading frame (ORF) of the resulting mRNA when the mutation occurs in an exon of the protein-coding gene (i.e., occurs a frameshift mutation), while this deletion may not have any effect if it is localized within the introns which are removed during RNA processing. A frameshift mutation will change the amino acids that are added to the nascent polypeptide chain during translation.

Answer:

Fermentation is an anaerobic process in which energy can be released from glucose even though oxygen is not available.

Explanation:

Fermentation occurs in yeast cells, and a form of fermentation takes place in bacteria and in the muscle cells of animals.

Answer:

it hatches and the baby comes out

Answer: The roots grow whichever way gravity will push them.

Answer:

DNA:

- is a single molecule that can be over 10,000,000 nucleotides long

- is usually double stranded  

- includes the base thymine

- is the genome for prokaryotic organisms

RNA:

- can be translated into a protein  

- is usually single stranded  

- includes ribose sugar  

- is a single molecule that can form a complex secondary structure

Explanation:

Deoxyribonucleic acid (DNA) is the hereditary genetic material of both prokaryotic and eukaryotic organisms, while RNA is the genetic material of many viruses. DNA is a double helix molecule composed of four types of nucleotides: a nitrogenous base (Adenine, Thymine, Cytosine and Guanine), a five-carbon sugar (i.e., deoxyribose), and a phosphate group. On the other hand, RNA is usually a single-stranded molecule whose nucleotides contain ribose sugars and Uracil bases replace Thymine bases. During translation, a type of RNA molecule referred to as messenger RNA (mRNA) is used as template to direct the synthesis of a polypeptide chain (protein). This RNA molecule can fold to form stable double-stranded RNA hairpins (i.e., secondary structures).

Explanation:

The cell cycle is the most important process in the growth of an organism.

Explanation:

Cell cycle is the fundamental process by which a cell matures, synthesises DNA and divides to form daughter cells. Somatic cells divide regularly.

All multicellular organisms use cell division for growth, maintenance and repair of cells and tissues. Unicellular organisms use this process to reproduce.

Cell cycle affects our daily lives. Most cancers are a result of inappropriate cell division arising due to aberrations in normal cell cycle regulation. Stem cell biology and regulation in growth of organs also involves extensive study of cell cycle.

Explanation:

Air masses form over regions where the air is stable for a long enough time. The air takes on the characteristics of the region. Air masses move when they are pushed by high level winds.

Answer:

true

Explanation:

this is it I think.:)

➜ Digetive enzymes convert the large and insoluble food molecules into small water molecules in the process of digestion. For example, pancreas secretes enzymes like amylase, trypsin and lipase. The enzyme amylase breakdown the starch, trypsin breaks down the proteins and lipase breaks down emulsified fats into simple sugars, amino acids and fatty acids, respectively.

Explanation:

The non living things in its environment is called a " matrix,"

A matrix is what supports a non living thing to reproduce, triple its existence & reproduce in mass quantities, like soil bacteria, and others..

Answer:

The shortcomings or drawbacks of cell theory are: Viruses are considered as acellular entities or organisms that do not have cell machinery, yet they are taken into account as organisms in this cell theory. Matthias Schleiden and Theodor Schwann did not know the mechanism of the cell.

Answer:

Where are the answers to choose from?

In any case, the ranvier nodes and myelin increase the speed

Answer:

Both are responsible for the economics fluctuations.

Explanation:

Fluctuations occurs in the economic condition of a country due to the inappropriate polices of the government because polices of government has direct impact on the the growth of economy of a country whereas the money supply tells us the current status of the economy of a country. The money supply refers to the total value of money available in an economy at a specific time so we can conclude that both money supply and inappropriate government policies leads to the economics fluctuations of a country.

Answer:

Grabbing a handful of mixed candy out of a bowl.

Explanation:

For all other options you are choosing specific items... such as a book from the library, or choosing items written on your grocery list, or choosing what to pack for lunch. Bycatch in fishing refers to catching extra fish, other than what you are selecting for. By grabbing a handful of mixed candy from a bowl you are not selecting for a specific 'fish'.

Answer:

c. decrease rate of muscle activity

Answer:

1. ATGGCTATT

2. UGGCAUGAC

3. mRNA: UAU-CCG-CAU, amino acids: tyrosine(tyr)-proline(pro)-histidine(his)

Explanation:

For DNA, the complementary bases are T=A and C=G. This means every time you see one of these letters, the corresponding letter goes with it. For mRNA, the bases are T=A, A=U, C=G. It is the same except now, there should be no "T" in the mRNA sequence. With amino acids, you would first code for the mRNA sequence, every three letters being the amino acid sequence. To find the amino acid, you would look at a codon chart unless your teacher wants you to memorize them.  The first three letters of the amino acid are the abbreviation.

Answer:

The xylem is one of the two types of tissue transported from the vascular plants, the other being the phloem.

Answer:

Xylem and phloem Plants have tissues to transport water, nutrients and minerals. Xylem transports water and mineral salts from the roots up to other parts of the plant, while phloem transports sucrose and amino acids between the leaves and other parts of the plant. Xylem and phloem in the center of the plant root

Answer:

Animals usually have 22 pairs of homolog chromosomes (autosomes) and as sex chromosomes 2 x chromosomes (in female), or 1 x and 1 y chromosome (in males), thus in total 46 chromosomes per body cell (see human karyogram; 2n = 46) and 92 chromatids per cell after replication.

Explanation:

42

Answer:

The answer is below

Explanation:

They provide structure and support, facilitate growth through mitosis, allow passive and active transport, produce energy, create metabolic reactions and aid in reproduction.
