The evidence that mitochondrial DNA of the species supports the idea that an evolutionary relationship exists between two hominid species. The correct option is B.
Relationships formed through the worldwide process of evolution between two separate creatures are known as evolutionaryrelationships.
They are, in other words, the connections between two species that shared an ancestor.
A group of organisms' evolutionary relationships and histories are known as its phylogeny in science.
A phylogeny describes the relationships between creatures, including where they are assumed to have originated from, which species they are most closely related to, and other information.
Purple non-sulfur bacteria were permanently enslaved to create mitochondria.
Through the development of sophisticated protein-import machinery and the insertion of protein carriers for host energy extraction into their inner membranes, these endosymbionts developed into organelles.
Thus, the correct option is B.

c)goldfish
d)human
3)when leaf has plenty of water
a) the guard cells swell and the stomates open
b)the guard cells swell and the stomates close
c)the guard cell lose pressure and the stomates open
d)the guard cells lose pressure and the stomates close
please helpppppp
Answer:
1. b. homeostasis: The internal balance of heat within an organism is maintained by the process of homeostasis. It is the ability of the organism to maintain the internal body temperature with respect to the changes that occur in the external environment.
2.d) human: The human beings are capable for maintaining the internal temperature due to homeostasis because they exhibit fat which allows them to maintain the internal heat.
3.c) the guard cell lose pressure and the stomata open: The stomata are small pores present on the underside of the leaf surface these are important for exchange of gases and water to the external environment. The water is lost by the stomata of the leaf during transpiration. When the plant requires to remove excess of water from the plant body it is evaporated from the stomata through transpiration.
The spinal cord is in the backbone (aka spine). The spinal cord is part of the central nervous system
How I remember where the spinal cord is the root of the words spine and spinal cord is similar
Hope this helped!

Explanation:
The functional unit of the kidney that filters blood and forms urine is the Nephron.
Nephron, a functional component of the kidney, is the organ responsible for producing urine as waste and extra chemicals are eliminated from the circulation.
The kidneys (pronephros) of early vertebrate embryos, amphibian larvae, and primordial fish have the most basic nephrons. Only somewhat more advanced in structure are the nephrons present in the kidneys (mesonephros) of frogs, most fish, and more advanced vertebrates during late embryonic development.
The adult kidneys, or metanephros, of land vertebrates like reptiles, birds, and mammals have the most developed nephrons.
Therefore, The functional unit of the kidney that filters blood and forms urine is the Nephron.

The nephron is the functional unit of the kidney. It filters blood and forms urine through a process involving the renal corpuscle and the renal tubule.
The functional unit of the kidney that filters blood and forms urine is the nephron. Kidneys contain millions of these tiny structures, and each nephron consists of two main parts: the renal corpuscle and the renal tubule. Blood enters the kidney through the renal artery, which splits to form a vast network of tiny capillaries. These capillaries form a tuft inside a cup-like structure known as the Bowman's capsule, which is a part of the renal corpuscle. The blood gets filtered here, and the filtrate moves into the renal tubule, where essential nutrients are reabsorbed, and wastes and excess water are concentrated into urine to be excreted.

B: tissue culture.
C: bacterial plasmids.
D: in vitro fertilization.
Answer:
The correct answer would be C: bacterial plasmids.
In plants, genetic transformation is usually achieved with the help of bacterial plasmid, especially Ti plasmid.
Ti plasmid is a tumor-inducing plasmid generally present in Agrobacterium tumifaciens. This bacteria has a natural ability to infect plant cells and caused tumors or crown gall disease in them. It is also known as natural genetic engineering of plants.
The modified or non-virulent Ti plasmid is used to transfer the gene of interest in the plants.
C. bacterial plasmids.
WHO in 1996 stated that the emergence of various types of new chemicals, both those contained in GMO organisms and their products, could potentially cause new diseases or even be a triggering factor for other diseases. For example, aad genes contained in transgenic cotton can move to the bacteria that causes gonorrhea (GO), Neisseria gonorrhoeae.
So, plasmids are bacterial DNA that is separate from the bacterial chromosomes. Plasmids can replicate themselves. Plasmids also contain various genes. The type, number of types, and number of each type (copy) of plasmids vary between cells. Even between cells in one bacterial species.
Plasmids usually contain between 5 and 100 genes that are not needed for bacterial survival. Genes for normal growth, metabolism, and cell structure are on the main bacterial chromosome. As long as the bacteria are developing in a low-pressure environment, removing all plasmids will not affect the ability of the bacteria to survive.
The function of plasmids is as a carrier of non-essential properties for bacterial growth. Essential here means having a direct role in metabolism and all biological activities that support bacterial growth.
Generally, plasmids have genes that are resistant to antibiotics. Antibiotics themselves, as you know, do not always exist in the environment, so the existence of these genes is not essential.
Plasmid function is also a determinant of nomenclature or naming of plasmids.
Ti plasmid, for example, which is named according to the ability of the plasmid to induce tumors in plants, forms a crown gal while Pym is the gene responsible for the process of forming nodules of Rhizobium bacterial species in legumes.
