Answer:
The structural and functional units of the kidney are called nephron.
Fun Facts about Nephron:
Nephron is the structural and functional unit of the kidney.
Its primary purpose is to maintain the concentration of water and soluble chemicals such as sodium salts in the blood by filtering it, reabsorbing what is needed, and excreting the excess as urine.
The glomerulus and renal (kidney) tubule are the two primary structures in each nephron. Each human kidney contains around 1,000,000 nephrons.
The structural and functional units of the kidney are called the nephrons. Each human kidney contains 8-10 lakhs nephrons.
What do you mean by Kidney?A Kidney may be defined as a pair of bean-shaped organs that eliminate waste and extra water from the blood and help keep chemicals balanced in the body.
Each nephron contains two structures i.e. Glomerulus and Tubules. The Glomerulus is a tough capillary through which a large amount of fluid is filtered from the blood.
Tubules are the other structure of the nephron in which the filtered fluid is converted into the urine.
Therefore, the structural and functional units of the kidney are called nephrons.

What are the different systems of classification of organisms
Answer:
kingdom, phylum, class, order, family, genus, and species.
Explanation:
kingdom, phylum, class, order, family, genus, and species.
Classification is a grouping of individuals according to their similarities and differences. It is used to group organisms according to ranks of similar characteristics and evolutionary basis.
What are the levels of classification?Classification system is divided into various levels in order to rank the organisms.
It has following levels:
Kingdom: It is the highest level of classification. There are a total of five kingdoms.Phylum: It is classified on the basis of phenetics and phylogenetics.Class: each phylum can contain multiple class.Family: it is group of genera having similar traits.Genus: it helps to determine species of the organisms.Species: it is the lowest rank in this category. It is group of organisms having similar characteristics.Thus, kingdom, phylum, class, family, genus, species are the classification system of organisms.

Which chromosomes shown below are homologous?
A) B and C
B) D and B
C) C and A
D) A and B
The chromosomes shown below are homologous: C and A, which are in option C as Homologous chromosomes are a pair of chromosomes that carry genes for the same traits, such as eye color or height.
What are homologous chromosomes?Homologous chromosomes are important for the process of meiosis, which is the type of cell division that produces gametes (sex cells) in eukaryotes. During meiosis, homologous chromosomes pair up and exchange genetic material in a process called crossing over. This allows for the mixing and shuffling of genetic information, which increases genetic diversity and contributes to the evolution of populations.
Hence, the chromosomes shown below are homologous in C and A, which are in option C. Homologous chromosomes are a pair of chromosomes that carry genes for the same traits, such as eye color or height.

According to the Frank-Starling Law of the heart, as contraction strength increases the stroke volume ________. Group of answer choices decreases shows no change increases
We can confirm that this law tells us that both stroke volume and contraction strength increase at the same time.
What is the Frank-Starling Law of the heart?This law indicates the relationship between the volume of the ventricle, specifically the left ventricle, and the strength of its contractions. It follows the logical approach that if there is more volume in the ventricle, the cardiac muscles will have to stretch to allow for the space, which in turn causes a much stronger contraction when these muscles activate.
Therefore, we can confirm that this law tells us that both stroke volume and contraction strength increase at the same time.

how is dna copied in your own words?
Answer:
Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA replication is one of the most basic processes that occurs within a cell. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, as the parent cell. To accomplish this, each strand of existing DNA acts as a template for replication.
Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin. Several enzymes and proteins then work together to prepare, or prime, the strands for duplication. Finally, a special enzyme called DNA polymerase organizes the assembly of the new DNA strands. The following description of this three-stage process applies generally to all cells, but specific variations within the process may occur depending on organism and cell type.
Answer:

The Toucan has a long, narrow beak that allows it to reach fruit that is hard to reach for other birds. Plants, like the Monstera Plant, in the rainforest have long, grooved leaves to drop water to the forest floor. The excessive water that falls in the rainforest could lead to mold, so the leaves adapted to have “drip tips” that allow the water to run off of the leaves.
What type of adaptations are these?
Answer:
The Toucan, as an animal, has to eat. So, the Toucan developed a more aggressive adaptation to get food. On the other hand, the Monstera Plant had to do something about the mold situation. So, it developed a less aggressive adaptation, more of a defensive one, to combat its issues.

Will mark brainliest if the answer is correct: ""how does the presence of reptilian and mammalian nephrons provide evidence for the relatedness of birds and other vertebrates?""
Answer:
Nephrons in birds, mammals, and reptiles are all extremely similar, more so than other structures in the bodies of different species, solidifying the relatedness through similarity.
Explanation:
Birds can be said to have "mammal-like" nephrons from the number of loops and overall structure of their kidneys, which, although they look very different, serve the same purpose and do it in largely the same way. Reptiles also have mammal-like nephrons, and it can be assumed that this evolutionary trait was kept because the specific structure of the nephrons is generally the most efficient.
The presence of reptilian and mammalian nephrons provide evidence for the relatedness of birds and other vertebrates because the nephrons are similar to that of reptiles and mammals and other birds and vertebrates.
What are nephrons?Nephrons are the functional unit of the kidney. There are many nephrons present in a kidney, it contains tubules and corpuscles.
The formation of urination is done by nephrons, the three functions of nephrons are filtration, reabsorption and secretion.
Thus, the presence of reptilian and mammalian nephrons provide evidence for the relatedness of birds and other vertebrates because the nephrons are similar to that of reptiles and mammals and other birds and vertebrates.

Obliquity or tilt is the inclination angle of the Earth's axis. It is responsible for seasonal changes. The correct option is A) The tilt of the Earth is responsible for the seasons.
What is the Earth's obliquity -tilt-?The term obliquity or tilt refers to the inclination of the axis of the Earth. The plane in which the Earth orbits around the sun is not orthogonal to the Earth’s axis of rotation. The axis has an inclination angle called ecliptic obliquity.
Obliquity is a determinant of seasons' existence. Thanks to this inclination in the axis of the Earth there are seasons. If tilt would equal cero, there would not be any season or temperature change in different regions of the Earth. So tilt becomes a significant factor, especially for high latitude areas.
Obliquity is one of the three Milankovitch cycles, together with precession and eccentricity. These are used to explain natural climatic changes through the history of the Earth.
The correct option is A). The tilt of the Earth is responsible for the seasons.
