dna is synthesized through a process known as _____.
Dna is synthesized through a process known as DNA Replication.
DNA is synthesized through a process known as - DNA replication or semiconservative replication.
DNA replicationsynthesis of new DNA. a double-stranded DNA molecule is copied to produce two identical DNA molecules.is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information or DNA.the replication takes place in the following steps:step 1in the nucleus of the cell the DNA double helix separates after that an enzyme named DNA helicase attaches to the DNA molecule and moves along the molecule and 'unzips' the two strands of DNA
Step 2since nucleotides are floating in the nucleus that means there are A, G, T and C's floating around also. these are bases that form hydrogen bonds with the bases of DNA strands.
Step 3
the enzyme they call DNA polymerase catalyzes the formation of the sugar-phosphate units at the sides of the helix and connects one base pair to the next one
Thus, DNA is synthesized through a process known as - DNA replication or semiconservative replication.

If two organisms of different species share more similar DNA sequences with each other than with other species, we can conclude that ________.
If two organisms of different species share more similar DNA sequences with each other than with other species, we can conclude that these two species are very closely related.
Anatomy and embryology, molecular biology, biogeography, and fossils all provide evidence for large-scale evolution (macroevolution).Different species with comparable architecture may be homologous (shared by ancestry) or analogous (shared due to similar selective pressures).The similarity of life's molecules is evidence that it shared an ancestor. The connections between different species can be discovered by comparing DNA sequences.Biogeography, the study of the geographical distribution of organisms, provides information on the origin and evolution of potential species.The presence of extinct species in the past and evidence of long-term evolutionary changes are both shown by fossils.Learn more about the Evidences of evolution with the help of the given link:

Match each part of the kidney with the correct label.
Kidneys are externally surrounded by a three-layer capsule, and internally composed of the cortex, medulla, and pelvis. In the image, 1) Cortex, 2) Medulla, 3) Sinuses , 4) Capsule.
What are the kidneys?
The kidneys are bean-shaped, bilateral urinary organs located at each side of the vertebral column, under the ribs, and behind the abdomen (superior right and left abdominal quadrants).
Their main function is to filtrate blood, eliminate wastes and water excess through urine, and keep internal homeostasis.
When blood enters the kidneys, water, salts, and other waste substances are eliminated as urine, and the filtrated blood returns to the organism.
Kidneys are composed of different parts.
Externally,
Renal fascia ⇒ External layerRenal fatty capsule ⇒ Media layerRenal fibrous capsule ⇒ Internal layer
Internally,
the renal cortex ⇒ produces erythropoietinrenal medulla ⇒ contains nephrons, which filtrate blood and produce urine.renal pelvis ⇒ ilion
The medulla is arranged as pyramidal masses composed of tubular structures. In between the pyramids, there are renal papilla and calyces.

HOPE IT HELPS!in aerobic respiration, what is the ultimate fate of the electrons released from the breakdown of glucose?
Answer:
They are combined with oxygen and hydrogen ions to form water.
Explanation:
The electron released from the breakdown of glucose transfers in the electron transport chain and is used in the formation of a proton gradient across the membrane.
What is aerobic respiration?In the presence of oxygen gas, cells undergo cellular respiration, which is how energy from food is produced. The majority of plants, animals, birds, humans, and other mammals all engage in this sort of respiration regularly. As byproducts of this process, water and carbon dioxide are created.
The energy that was stored in carbohydrates and lipids during photosynthesis is released during the process of aerobic respiration and made available to living things. Glycolysis, the link reaction, the Krebs cycle, and oxidative phosphorylation are the four phases.
Protons are pushed out of the matrix and into the intermembrane space as a result of the electrons moving through the electron transport chain. The electrons eventually reach oxygen, which reacts with protons to create water.
