Answer:
The correct sequence is: Hypothalamus, Pituitary, Adrenal
Explanation:
The endocrine system comprises of cells, tissues, and organs that discharge hormones as an essential or auxiliary capacity. The endocrine gland is the significant part in this system. The essential capacity of these ductless glands is to discharge their hormones straightforwardly into the encompassing liquid. The interstitial liquid and the veins at that point transport the hormones all through the body. The endocrine system incorporates the pituitary, thyroid, parathyroid, adrenal, and pineal organs
If a double-stranded segment of DNA has been found to have 23 purines and 15 thymines, how many guanines are there?
Answer: 4 Guanines
Explanation: Following Chargaff's ratio that describes the ration of purines to pyrimidines as 1:1, if there are 23 purines, it follows that there should be 23 pyrimidines; 15 Thymines should therefore be hydrogen bonded to 15 Adenines by complementary base pairing.
We are then left with 8 nucleotides composed of guanines and cytosines in complementary base pairs. This means that half that number (4) should be guanines and the rest cytosines.
The DNA is a double-stranded molecule, which is made up of purine, pyrimidine, a pentose sugar, and phosphate backbone. Chargaff's rule states that any species will have a stoichiometric ratio of 1:1.
The number of guanines in the double-stranded DNA is 4.
In the DNA, the base pairing occurs as:
The guanines bind with cytosine through hydrogen bonding. The adenine binds with thymine with two hydrogen bonds.In the given nucleotide, there are 23 purines (guanine and adenine). There are 15 thymines in the DNA molecule. Based on the Chargaff rule, the 15 thymines will bind to adenine, leaving only 4 guanines and 4 cytosines. Thus, there will be 4 cytosines left to bond with the guanines to achieve Chargaff's ratio of 1:1.
Therefore, the guanine in the nucleotides will be 4.

Which organisms replicate cells by mitosis?
Answer:
All organisms, both prokaryotes and eukaryotes, can replicate cells by mitosis.
Explanation:
Mitosis is the process of cell division where, from a progenitor cell, two identical daughter cells are obtained. In the human being this process is carried out by somatic cells.
Cell division by mitosis is carried out by all living beings:
Prokaryotic organisms, unicellular, use it as a means to reproduce. Eukaryotic organisms, most of them pluricellular, use it in the processes of growth, development, repair and regeneration of tissues.All living beings can perform mitosis as a process of cell replication, although with different objectives.

Answer: run off from land/rivers and phytoplankton blooms
Explanation:

The two factors that are other than the rate of nitrogen fixation that fit the marine ecosystem are runoff from the land or rivers and the phytoplankton blooms
Waht is nitrogen fixation ?Nitrogen fixation refers to the chemical process by which molecule N2 has a strong Tripple covalent bond and in the air, it gets coveted into NH3 or a related nitrogenous compound that is typically in soil or aquatic system.
The fixation is essential for life as inorganic nitrogen compounds are needed for the biosynthesis of nitgen-containing organic compounds like amino acids.
As nitrogen is easily found in soil and can be added by fertilizers it ends as runoff and damages the ecosystem.

Answer:
Carbon monoxide can kill. The gas forms when there is not enough oxygen to produce carbon dioxide -- essentially when the carbon in fuel is not burned completely. Carbon monoxide prevents oxygen in the blood from being carried throughout the body, causing asphyxiation.

What is a ribososme?Ribosomes, also called Palad granules (after their discoverer George Palade, for their granular structure), are macromolecular machinery found in all cells that perform biological protein synthesis (mRNA translation).Ribosomes join amino acids in an order determined by the codons of the messenger RNA (mRNA) molecule to form a polypeptide chain. Ribosomes are composed of two major components, the large and small ribosomal subunits.Each subunit is composed of one or more ribosomal RNA (rRNA) molecules and many ribosomal proteins (RPs or r-proteins).Ribosomes and related molecules are also known as the translational apparatus.The ribosome is a ribonucleoprotein complex because it is composed of a complex of RNA and protein.Each ribosome is composed of smaller (30S) and larger (50S) building blocks called subunits.

which kind of cells carry out the process of cellular respiration?
All living cells must carry out cellular respiration. It can be aerobic or anaerobic respiration. Prokaryotic cells carry out cellular respiration within the cytoplasm or on the inner surfaces of the cells, while Mitochondria carry out the cellular respiration in eukaryotic cells. They are also called as the 'Power house' of the cell as they produce the energy needed to the cell to function properly.
