Which of the following structures are found only in embryos that shows the relationship of humans to other species?
Select one:
Lungs
Brains
Gills
Appendix
Answer:
pls read this paragraph
Explanation:
Vestigiality is the retention during the process of evolution of genetically determined structures or attributes that have lost some or all of the ancestral function in a given species.[1] Assessment of the vestigiality must generally rely on comparison with homologous features in related species. The emergence of vestigiality occurs by normal evolutionary processes, typically by loss of function of a feature that is no longer subject to positive selection pressures when it loses its value in a changing environment. The feature may be selected against more urgently when its function becomes definitively harmful, but if the lack of the feature provides no advantage, and its presence provides no disadvantage, the feature may not be phased out by natural selection and persist across species.

In humans the vermiform appendix is a vestigial structure; it has lost much of its ancestral function.
Examples of vestigial structures (also called degenerate, atrophied, or rudimentary organs) are the loss of functional wings in island-dwelling birds; the human appendix and vomeronasal organ; and the hindlimbs of the snake and whale.
state three features of myriapods that can be used to distinguish them from other arthropods
Answer:
Mandibles (lower jaw) and maxillae (upper jaw)
Two body sections (head and trunk)
One pair of antennae on the head
Explanation:
hope this helps! have a great day / night
Although Myriapods share many characteristics with other arthropods, they distinguish for having an elongated and multisegmented body, one or two pairs of legs per segment, two antennae, and rolling-up ability
----------------------------------------
As the name refers to, Myriapods have many feet. They characterize because their bodies are very elongated and divided into multiple segments. From each of the rings, emerge one or two pairs of legs.
As every arthropod, their bodies are segmented and covered by a cuticle for protection and to avoid dehydration.
Their heads carry two antennae, ocellus, and a mouth with prominent buccal appendixes. Some of them might be poisonous.
They can be slow when moving, but they are well-adapted to move through leaves and other organic material. But because they move slowly, they need a protection strategy to avoid predation. This strategy is rolling. They can roll up, and remaining like a boll, until the predator leaves.

Which of the following is true about the coasts of North and South America? O A. Little industry is located along the coasts, B. There are few cities and the population is sparse. O c. A majority of the population is located there. D. People go to the coasts only when on vacation,
Answer:
The correct answer is C. In North and South America, a majority of the population is located on the coasts.
Explanation:
Historically, the vast majority of civilizations have sought to establish their urban centers around bodies of water, be they rivers or seas, that allow them a rapid expansion outward as well as channels through which to channel trade. Thus, it can be seen how throughout the world and especially the American continent, large cities and population centers are located primarily on the coasts. Examples of this situation are Vancouver in Canada, New York and Los Angeles in the United States, Rio de Janeiro in Brazil or Buenos Aires in Argentina.

if hypertonic has more solutes than hypotonic does hypertonic have more or less water?
Answer:
Explanation:
Hypertonic solutions have less water ( and more solute such as salt or sugar ) than a cell. ... Hypotonic solutions have more water than a cell. Tapwater and pure water are hypotonic. A single animal cell ( like a red blood cell) placed in a hypotonic solution will fill up with water and then burst.

A scientist wants to determine whether a mutant phenotype is due to the loss of gene C or gene D, which are both deleted in a mutant fly with abnormal eyes. Mutant flies with that have a transgenic gene C have wild-type eyes, whereas mutant flies that have a transgenic gene D have abnormal eyes. What can be concluded from these results
Answer:
a transgenic copy of the gene C is sufficient to restore normal eye development
Explanation:
In genetics, there are diverse approaches to determining a gene's function. For example, it is possible to use a complementation test to determine loss-of-function recessive mutations when it is unknown if such mutations fall in the same or in different genes. Similarly to the generation of loss-of-function phenotypes, it is possible to insert a gene and thus produce a gain-of-function mutation that restores normal gene function (i.e., to restore the wild phenotype). Moreover, transgenic organisms refer to genetic engineering techniques by which any foreign or modified gene is inserted in the genome of an organism, which can also be used to study gene function. In this case, the restoration of the normal phenotype (wild-type eyes) is associated with the expression of the transgenic gene C, thereby evidencing that the gene C is required for normal eye development. In the last years, transgenic models have shed light on developmental pathways and on gene function.

- Refer to the basic theory in genetics.
Climate change is leading to many changes to populations around the world. Some species are now able to live in environments that were to cold before. Other species are moving to areas more like the habitat they are most suited to. When a species moves into an area it is called ____, and when it moves out of an area it is called ____.
A
immigration, emigration
B
emigration, immigration
C
migration, extinction
Answer:
The correct answer is - A. immigration, emigration.
Explanation:
In biology, immigration is the act of joining or entering a new species or population of organisms into a particular area or population. These new species carry new alleles and traits with themself in the area and population increasing the population.
On other hand, emigration is the act of leaving the area where a population used to live due to changes in the habitat or the particular habitat is not suitable anymore for the population.
What is the answer to number 1
Answer:hi
Explanation:hi
Answer:
TTT GCC AGT
Explanation:
How does this affect the change?
Answer: B. It sped up evolutionary change by increasing genetic variation.
Explanation:
Evolution works when organisms with genes that are better suited to the environment pass on their genes to future generations.
Sexual reproduction sped up this process because it allowed for genetic variation as genes from the two mates would be passed on the next generation instead of one organism as had been the case with asexual production.
With genes from both mates mixing up and going into the next generation, more genetic variations were produced which allowed for the organisms to better adapt to the environment.

In a free market system, price controls can include both floors and ceilings.
The government imposes these limitations in order to regulate the retail value of specific goods and services. Rather than have limits on both sides, most items have either a floor or a ceiling imposed on them.
