which is not a function of the lymphatic system? question 5 options: 1) transports dietary lipids 2) returns excess interstitial fluid to the bloodstream 3) houses and develops lymphocytes 4) generates immune responses 5) no exceptions; all choices are functions of the lymphatic system.
The correct answer for the given question is: (5) No exceptions, i.e. all of the options show the functions of the lymphatic system.
The lymphatic system has several functions in the body. It is responsible for regulating the fluid levels in the body. It does so by removing extra interstitial fluid from the respective tissues and redirecting it into the bloodstream. The lymphatic system also takes up dietary fats or lipids and is also responsible for the transport of these lipids.
The lymphatic system also acts as a site for the storage as well as the development of lymphocytes. It is also associated with the generation of immune reactions.

how did the evolution of the jaw contribute to diversification of early vertebrate lineages? group of answer choices it made additional food sources available. it allowed for smaller body size. it was the first stage in development of a bony skull. it increased the surface area for respiration and feeding.
The evolution of the jaw contribute to diversification of early vertebrate lineages as the group of answer choices it made additional food sources available. Thus, option A is correct.
What is evolution?
Evolution has the shift in the biological population's heritable traits over successive generations. These traits are the result of genes that are expressed during reproduction and transferred from parent to offspring.
The process of mutation, genetic recombination, and other causes of genetic diversity frequently result in the different traits existing within a population.
When these variations are subjected to evolutionary processes like natural selection (which includes sexual selection) and genetic drift, specific traits within a population start to become more or less prevalent. This is when evolution happens.
Therefore, The evolution of the jaw contribute to diversification of early vertebrate lineages as the group of answer choices it made additional food sources available. Thus, option A is correct.

10 things about genetically different amongst humans that is most likely due to crossing over?
Each chromosome is a distinct pattern of DNA that represents portions of the genome that have been passed down from generation to generation
What is the genetic result of crossing over?The exchange of genetic material across homologous chromosomes is known as crossing-over. It results in new gene combinations on each chromosome. During meiosis, when cells divide, homologous chromosomes are randomly distributed to daughter cells, while distinct chromosomes segregate independently of one another.The closer two genes were on a chromosome, the more likely they were to be inherited together. Genes placed farther apart on the same chromosome, on the other hand, were more likely to be separated during recombination.Each chromosome is a distinct pattern of DNA that represents portions of the genome that have been passed down from generation to generation, occasionally being scrambled between chromosomal pairs.To learn more about chromosomes refer,

Plants are similar to algae in the following manner:-
Both of them can perform photosynthesis.
Plants as well as algae produce their food through the process of photosynthesis. During this process, they take up Carbon dioxide gas as well as water and with the help of chlorophyll pigments along with the light absorbed from the Sun, they produce glucose and give out Oxygen gas.

in goldfish, the twin-tailed trait has two alleles. goldfish that have a heterozygous genotype produce the single-tailed phenotype. this means that goldfish with the twin-tailed phenotype must be
Answer:
Homozygous recessive
Explanation:
This is because if single-tailed is heterozygous the alleles would be Tt which would mean the single-tailed trait is dominant and twin-tailed is recessive.
T = Single t = twin
So, for a recessive trait to show there would have to be two of them with would make it tt which is homozygous recessive since both of them are recessive.
which of the following statements about ips cells is false? group of answer choices ips cells can be made by adding a combination of transcription regulators to a fibroblast. a cell that is dedifferentiated to become an ips cell will undergo changes to its gene expression profile. stimulation by extracellular signal molecules causes ips cells to differentiate. ips cells made from mouse cells can differentiate into almost any human cell type.
iPS cells made from mouse cells have the ability to develop into practically every form of human cell. This assertion is untrue. IPS cells are pluripotent, which means they have the potential to develop into any form of cell found in the body.
Adipocytes, cardiomyocytes, primitive hematopoietic cells, pancreatic beta-cells, and a number of distinct neuronal cell types have all been developed from human iPS cells. The development of iPSCs, which are made from skin or blood cells and reprogrammed to return to a pluripotent stage akin to that of an embryo, has made it possible to create an endless source of any type of human cell needed for therapeutic purposes.
As a result, we can conclude that the claim stated in option D—that iPS cells produced from mouse cells can develop into virtually every type of human cell—is untrue.
