Help me please!!!!!!!!!

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.

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 human genome contains approximately 3 billion of these base pairs, which reside in the 23 pairs of chromosomes within the nucleus of all our cells. Each chromosome contains hundreds to thousands of genes, which carry the instructions for making proteins.

What is chromosome ?

A chromosome is a thread-like structure present in the nucleus of cells such as plant, animal and human cells and it is made of a molecule of DNA (Deoxyribonucleic acid) and histone proteins.

It is composed of three components, DNA, proteins and RNA,  amount of the DNA content ranges from 30 to 40 %, the amount of proteins from 50 to 65%, and small amount of RNA from 1 to 10%.

Two types of protein present in DNA such as histone and non-histones proteins, histone constitute large amount (90% of total protein), whereas non-histone is present in small amount (around 10% of total protein).

The histone protein is basic, whereas, the DNA is acidic, so it can be neutralized; DNA in chromosome  is present in two forms such as Euchromatin and Heterochromatin.

Chromosomes have hereditary function that are capable of self-duplication and they have thread-like structures seen inside the nucleus of plant and animal. In plants, they go through a cycle called alteration of generation that has multicellular stages. One is sporophyte that is a diploid, and the other is gametophyte with a haploid.

Moreover, spores are produce through meiosis so it go through a process of chromosome reduction in order to create a haploid spores. While, gametes undergo mitosis and the structure is already a haploid, which means that the number of chromosomes will not change in order to produce haploid. In this case, the plant have both spores and gametes and the similarities is that, they are both singles celled and a haploid. Therefore, the number of the chromosome in the gametophyte generation is also 32.

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

Explanation:

In cycle sequencing technique, four distinctive fluorescently named dideoxyNTPs are utilized ( ddATP, ddGTP, ddCTP and ddTTP) notwithstanding ordinary dNTPs. each ddNTP marked with an alternate fluorescent color. Toward the finish of the experiment, the outcome yields various pieces of variable lengths each resulting in a solitary terminal fluorescent ddNTP towards the end.

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:

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:

laterite

Explanation:

Laterite soil is found in warm, humid climates. So, the correct option is B.

Climate may be defined as the description of the long-term pattern of weather in a particular area.

Laterite soil is found in the soil layer which is rich in iron oxide and derived from a wide variety of rocks weathering under strongly oxidizing and leaching conditions.

Therefore, Laterite soil is found in warm, humid climates.
