phylogenomic analysis of the parrots of the world distinguishes artifactual from biological sources of gene tree discordance
The correct answer is heterogeneous levels of phylogenetic signal among individuals within datasets may cause artifactual sources of topological discordance.
Individuals with varying levels of phylogenetic signal within datasets may be artifactual sources of topological discordance. We investigated how the information content of tips and subclades influences topological discordance in the parrots (Order: Psittaciformes), a diverse and critically endangered clade of nearly 400 species. We estimated concatenated and species trees for 382 ingroup taxa using ultra conserved elements from 96% of the clade's species-level diversity. We discovered that discordance between tree topologies was most common at nodes dating from the late Miocene to the Pliocene, and frequently at the taxonomic level of genus. a better predictor of metrics supporting alternative topologies.

During glycolysis, a 6-carbon sugar diphosphate molecule is split into two 3-carbon sugar phosphate molecules. True or false?.
The given statement is true. During glycolysis, a 6-carbon sugar diphosphate that is fructose-1,6-bisphosphate is splitted into two 3 carbon sugar phosphate molecules that are dihydroxyacetone phosphate and glyceraldehyde-3-phosphate.
What is glycolysis?Glycolysis is a 10-step reaction wherein glucose is divided into two pyruvate molecules, each of which has three carbons.
Glycolysis is the initial step in the process of cellular respiration in organisms. However, many anaerobic organisms also contain this route since glycolysis does not require oxygen.
What are the various steps involved in glycolysis?1. The conversion of D-glucose into glucose-6-phosphate is the initial step in the glycolysis process. The enzyme catalyst in this case is hexokinase.
2.This second phase involves the conversion of fructose 6-phosphate from glucose 6-phosphate.
3. Using magnesium as a cofactor, fructose 6-phosphate is changed into fructose 1,6-bisphosphate.
4. Fructose 1, 6-bisphosphate is split into two identical sugars by the enzyme aldolase. Dihydroxyacetone phosphate (DHAP) and glyceraldehyde 3-phosphate are the names of these two sugars.
5.The molecules glyceraldehyde 3-phosphate and dihydroxyacetone phosphate (DHAP) are quickly interconverted by the enzyme triphosphate isomerase.
The first five steps listed above are regarded as the initial phase.
.Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) converts glyceraldehyde 3-phosphate into 1,3-bisphosphoglycerate by dehydrating it and adding an inorganic phosphate.
7. To create ATP and 3-phosphoglycerate, a phosphate group from 1,3-bisphosphoglycerate is transferred to ADP.
8. In this step, Phosphorous from 3-phosphoglycerate is transferred from the third carbon to the second carbon to generate 2-phosphoglycerate.
9. An enzyme removes a water molecule from 2-phosphoglycerate to create phosphoenolpyruvic acid (PEP).
10. Phosphoenol pyruvic acid is converted to pyruvate.

: The given statement is True.
A 6-carbon sugar molecule is divided during glycolysis into two 3-carbon sugar molecules. Glucose, a 6-carbon sugar molecule, is also known as a hexose sugar. 3-phosphoglycerate refers to the 3-carbon sugar molecules created during glycolysis. Cells use the process of glycolysis to break down glucose and produce ATP as a source of energy (adenosine triphosphate). There is no need for oxygen because the process takes place in the cytosol of cells (anaerobic). All cells use the same pathway to produce energy, and it is the first stage in the breakdown of glucose to do so.

How do sediments eroded by water become more smooth and round
Answer: Liquid water is the major agent of erosion on Earth. Rain, rivers, floods, lakes, and the ocean carry away bits of soil and sand and slowly wash away the sediment causing it to become more round and smooth.
I hope this helps!
Answer:
through friction.
Explanation:
The sediments rub together to become smoother. Sediments that are transported in a mass by water or stream are in motion with respect to the motion of the stream water. They bump into each other which makes extruding parts vulnerable to getting knocked off which makes these particles round.

status, trends, and equilibrium abundance estimates of the translocated sea otter population in washington state
Prior to their local extinction in the early 1900s as a result of the marine fur trade, sea otters (Enhydra lutris kenyoni) once lived in Washington State, USA.
After being extinct, 59 sea otters were brought from Amchitka Island in Alaska, USA, to the coast of Washington. Of these, 29 were released in 1969 at Point Grenville and 30 in 1970 at La Push.
Estimates of the translocated sea otter population's status, trends, and equilibrium abundance in Washington StateA chosen sample level and a target geographic distribution are the two key goals set forth by the Washington Department of Fish and Wildlife for the recovery of sea otters. Estimations of these characteristics have significant management consequences because recovery requirements are dependent on estimates of populations abundance, equilibrium abundance, and geographic distribution. In order to assess history and present abundance as well as equilibrium abundance at various spatial scales, we collated all survey data for sea otters that have been recorded in Washington State since their relocation (1977–2019). As a foundation for a sensitivity analysis to gauge the relative impact of movement behavior, in Journal of Wildlife Management, we then utilized forward predictions of population dynamics to investigate different scenarios of range recolonization.learn more about sea otters here

Energy flow in an ecosystem is best represented by c. food webs.
In the field of ecology, we can describe the food web as a representation of all the food chains of a particular ecosystem.
In an ecosystem, there are many organisms that act as prey and predators for each other through which energy flows in the ecosystem.
As a food web will represent all the prey as well as predator organisms and also depict what eats what, hence the energy flow in an ecosystem can best be represented by food webs.
Other options, such as food chain, are not correct as a food chain is a representation of a single energy flow system of an ecosystem. To determine the energy flow of the whole ecosystem, a food web is required.

Explanation:
A cut will usually just close itself up but an amputation cant do that.
How can a mutation affect protein synthesis by a cell? do you think there are different consequences if it happens in a gamete cell (sperm or egg) versus a non-gamete cell?
A mutation affects protein synthesis by a cell by changing the instructions of genes for making a protein, as a variant can cause a protein to malfunction or not to be produced at all. Yes, there are different consequences if it happens in a gamete cell versus a non-gamete cell.
The mutation affects protein synthesis in a cell due to the involvement of genes as they are responsible for coding proteins, needed for all of the functions of the body and to build strong body structures. So, a mutation that is affecting could change the way how a protein is made.
If a mutation occurs in cells that are making gametes by the process of meiosis or during the meiosis process itself, it has the chance to be passed on to the next offspring and will contribute to the condition of genetic variability of a particular population. Mutations are considered the sole source of genetic variability that may have the chance to occur in asexual reproduction.
If a gene is made to alter in a germ cell, then the mutation will be termed germinal mutation because germ cells will give rise to gametes so that some gametes will carry the process of mutation and can be passed on to the subsequent generations.

Which reactant of photosynthesis is also involved in climate change?
A oxygen
B carbon dioxide
C water
D sugar
Answer:
B. Carbon dioxide
Explanation:
First of all, let’s write out the photosynthesis equation to identify the products and reactants.
6CO2 + 6H2O + energy —> C6H12O6 + 6H2O
In a chemical equation with the arrow pointing right, the reactants are on the left and the products on the right.
In photosynthesis, the reactants, carbon dioxide, water, and energy, react to form the products of glucose (sugar) and oxygen.
Now, let’s look at the answer choices. We can automatically eliminate choices A (oxygen) and D (sugar) because they are products.
We are left with B (carbon dioxide) and C (water). Water isn’t really considered a major contributor to climate change. Carbon dioxide is a greenhouse gas that traps heat in the atmosphere, causing climate change.
Therefore, the best answer choice is B. Carbon dioxide

despite the truth that many animals shield important sources from conspecifics at some stage in interactions, several primate species automatically have interaction in tolerant encounters. In terms of evolutionary process intergroup relationships, as an instance, African apes and people (Homininae) show off full-size range, and local human groups are hooked up thru a community of affiliative relationships amongst corporations. We have to have a look at variance between species, between populations, and inside populations to be able to comprehend this range and its evolution. even as bonobos' intergroup connections are typically affiliative, each jap and western chimpanzees often exhibit adverse intergroup ties. despite the fact that the percentages of corporations with numerous adult males within the genus Gorilla range, all subspecies show off great domestic range overlap and each adversarial and affiliative intergroup interactions. in regards to neighborhood populations of the same (sub)species, there are few variations between Pan and Gorilla. The distribution of girls within corporations seems to play a position in the affiliative relationships among bonobos, however intergroup connections differ in the identical neighborhood populations in different species. those patterns in bonobos seem like just like the ones in local human communities, wherein lady dispersal amongst corporations performs a huge function in affiliative relationships and intergroup connections vary for extraordinary combinations of companies. All gorilla subspecies showcase a variety of intergroup connections, from affiliative to competitive, and relatives relationships between leading males are vital to the development of affiliative relationships. studies on intergroup variation, the roles played through ladies and men in that variation, and the genetic make-up of the neighborhood populations may additionally assist us higher apprehend the evolutionary process that gave upward thrust to neighborhood groups within the Homininae.To learn more about the evolutionary process here:-
