Answer:
The correct statements are: A and D.
Explanation:
a. Both the alveolar wall and capillary wall contribute to the respiratory membrane.
The respiratory membrane is a more or less homogeneous surface composed of a set of structures that gases must cross between the alveolus and the pulmonary capillary. When blood reaches the lungs it has a high CO2 content and a low O2 content. O2 passes by diffusion through the alveolar walls and capillaries into the blood. There it is transported by hemoglobin, which will take it to the cells of the body where, by the same diffusion process, it will pass inside them for later use.
d. The alveoli have a simple squamous epithelium to allow for diffusion of oxygen and carbon dioxide across the respiratory membrane.
The function of the lungs is to carry out the gas exchange with the blood, for this the alveoli are in close contact with the capillaries. The simple flat squamous epithelium lines the alveoli of the lungs, they are flattened and irregular cells in a single cell layer that allow the easy diffusion of water, gases and other substances. In the alveoli there is the passage of oxygen from the air to the blood and the passage of carbon dioxide from the blood to the air.

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'.

money supply and inappropriate government policies of economics fluctuations
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.
Which of the three fundamental tissues have a secondary cell well? (Parenchyma, collenchyma and sclerenchyma)
If an animal has 21 chromosomes before replication, how many do they have after?
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.

g Classify the statements as describing deoxyribonucleic acid (DNA) or ribonucleic acid (RNA). DNA RNA is a single molecule that can be over 10,000,000 nucleotides long is usually double stranded includes the base thymine can be translated into a protein is the genome for prokaryotic organisms is usually single stranded includes ribose sugar is a single molecule that can form a complex secondary structure
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).

What is the function of digestive enzymes ?
Answer in brief..I'll reward.
➜ 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.

what is xylem and phloem in science?
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

Given the following sequence of DNA, write the correct sequence of complementary DNA bases.
TACCGATAA
Given the following sequence of DNA, write the correct sequence of complementary mRNA.
ACCGTACTG
Given the following sequence of DNA write the correct sequence of amino acids.
ATAGGCGTA
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.

d) During Transcription, a nucleotide has been deleted. Explain the effect this will have
on DNA as well as what happens in each step along the way to a protein.
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.

Which is a correct graphical representation of the organization levels of a
biological system?
Answer:
1. Biosphere
2. Ecosystem
3. Community
4. Population
Explanation:
The correct graphical representation of the organization levels of a biological system is as follows:
Cells, tissues, organs, organ systems, organisms, populations, communities, ecosystems, and biosphere. What is the level of organization of the biological system?The level of the biological system may be defined as the arrangement of structures that are usually characterized by relationships with things at higher levels that are being composed of things at the next lower level. A cell is the smallest level of organization for living things while the biosphere is the highest level of organization for living things.
A cell is the basic structural and functional unit of living organisms. The collection of cells gives rise to the formation of tissues which are combindly known as organs. Organs give rise to the organ system that completely formed a living entity.
Therefore, the correct graphical representation of the organization levels of a biological system is well represented above.
