Answers

Answer 1

Option B. is correct, Mauna Loa measures the various gases in the air to look for any changes in the Earth's climate. Carbon monoxide, methane, nitrous oxide, and sulphur dioxide are some of the gases they measure.

The longest running record of atmospheric carbon dioxide concentrations, the main greenhouse gas causing global climate change, is the Mauna Loa Carbon Dioxide Record. The historical network of in situ measurements of surface air temperatures and ocean surface temperatures provides the instrumental temperature record with the temperature of the Earth's climate system. Finally, heat emanating from the Earth warms the ice sheet's base layers. However, climatologists can calibrate the data by comparing the thermometer temperatures with the oxygen isotope record, as these directly measured temperatures reflect an approximate average—a record of trends, not changeable, daily temperatures.

Answers

Mitosis and meiosis are cell division processes that vary in the type and number of cells they produce (somatic cells or gametes), the nuber of chromosomes new cells carry (haploid n and diploid 2n), and their genetic variation. 1) Asexual reproduction 2) Sexual reproduction 3) Because both daughter cells are the same and are identical to their parental cell. 4) Because meiotic division introduces genetic variation among the daughter cells. 5) haploid cells produced by meiosis. 6) Haploid. 7) Zygote. 8) Somatic cells. 9) Gametes have n number of chromosomes. 10) Gametes have 32 chromosomes. Somatic cells have 64 chromosomes

What are mitosis and meiosis?

Mitosis and meiosis are both cell division processes. Both of them follow the interphase, and both are followed by cytokinesis. However, they express differences.

Through mitosis, a diploid somatic cell (2n) produces two daughter diploid cells (2n).

Mitosis occurs in somatic cells and germ cells. This division event can be considered an asexual reproduction process.

Through meiosis, gametes are produced from germ cells. 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.

This division event occurs during sexual reproduction.

1. Mitosis is categorized as a form of _asexual_ reproduction.

2. Meiosis is categorized as a form of _sexual_ reproduction.

3. Why are the offspring created by mitosis considered to be clones?

   Because both daughter cells are the same and are identical to their parental cell.

4. Are clones created during meiosis? (Explain your answer.)

  No, because random events occur during meiosis (like crossing over and independent assortment) that introduce genetic variation among the daughter cells. Gametes are genetically different from each other.

5. What are gametes?

Gametes are the haploid cells produced by meiosis.

6. Human gametes should contain _23_ chromosomes each. This number would be considered the _haploid_ (haploid/diploid) number for humans. The symbol for this is _n_.

7. After fertilization, the fertilized egg is referred to as a _zygote_.

8. What type of cells have the ‘2n’ number of chromosomes? Somatic cells.

9. What type of cells have the ‘n’ number of chromosomes? When do these cells have ‘2n’ chromosomes?

Gametes have n number of chromosomes. When gametes mergen and produce a zygote, they have 2n number of chromosomes. Before meiosis I, germ cells have 2n number of chromosomes.

what type of incision is made for excisional biopsy of a centrally located breast mass involving the lactiferous ducts?

Answers

An excisional biopsy is a surgical procedure used to remove a sample of tissue from a specific area of the body for further examination. The type of incision made for an excisional biopsy of a centrally located breast mass involving the lactiferous ducts would depend on the location and size of the mass.

If the mass is located in the central portion of the breast, it is likely that the surgeon would make an incision that allows access to the mass while minimizing damage to the surrounding tissue and structures. One common approach is to make an incision in the inframammary fold, which is the natural crease under the breast. This allows the surgeon to access the mass from the side of the breast and minimize the visibility of the incision on the breast.

The blood in an artery flows faster and at higher pressure. Explain why.

Answers

Answer:

Arteries carry blood from the heart to the tissues. ... The blood pressure drops after the blood passes through the capillaries, and with a larger lumen, reducing the resistance to allow blood flow at a lower pressure, veins have a lower blood pressure. Hence, arterial blood pressure is higher than venous blood pressure.

Answer:

The blood in an artery flows faster and at higher pressure. Its because pressure is a measure of the force that the blood exerts against the vessel walls as it moves the blood through the vessels. Like all fluids, blood flows from a high pressure area to a region with lower pressure. Blood flows in the same direction as the decreasing pressure gradient: arteries to capillaries to veins.Moreover the arteries have thicker smooth muscle and connective tissue than the veins to accommodate the higher pressure and speed of freshly pumped blood. The veins are thinner walled as the pressure and rate of flow are much lower.

Answers

There are several reasons that might best explain the decline of American lobster populations. Some of the potential reasons include overfishing, climate change, habitat degradation.

Overfishing: The demand for American lobster as a popular seafood item has led to overfishing in southern New England, which has reduced the number of lobsters in the wild.Climate change: Rising ocean temperatures and changes in ocean chemistry caused by climate change have led to a decrease in the number of lobsters in southern New England.Disease: A disease known as "shell disease" has been found to be affecting lobsters in southern New England, which has led to a decrease in population.Habitat degradation: Pollution, destruction of coastal habitats and human development can also cause a decline of lobsters population.

why are triacylglycerols the major form of stored energy instead of glucose?

Answers

Triacylglycerols (TAGs), commonly known as triglycerides, are the major form of stored energy in the body for several reasons. Energy density: Triacylglycerols contain more than twice the amount of energy per gram compared to glucose.

Hydrophobic nature: Triacylglycerols are non-polar molecules and hydrophobic, meaning they do not readily dissolve in water. This property allows them to be stored in specialized adipose tissues as lipid droplets without affecting cellular processes or causing osmotic imbalances. Storage efficiency: Triacylglycerols are highly efficient for long-term energy storage because they are stored with minimal associated water. Slow energy release: When energy is needed, the breakdown of triacylglycerols releases fatty acids, which can be used by cells for energy production through processes like beta-oxidation.

Overall, triacylglycerols provide a highly efficient and long-lasting energy reserve in the body, making them the preferred form of stored energy compared to glucose.

The three-nucleotide sequence on tRNA that is complementary to an mRNA codon is called an anticodon.

During protein synthesis, the genetic information encoded in mRNA is translated into a sequence of amino acids. Transfer RNA (tRNA) molecules play a crucial role in this process by carrying specific amino acids and recognizing the corresponding codons on mRNA.

Each tRNA molecule possesses a unique three-nucleotide sequence known as an anticodon. The anticodon is complementary to the codon on mRNA, allowing tRNA to bind to the mRNA and bring the correct amino acid for incorporation into the growing polypeptide chain. This complementary base pairing between the anticodon and the mRNA codon ensures the accurate translation of the genetic code.
