a population of rodents, called population a, lived on a large landmass. one group of the population dispersed to a nearby island. two million years later, the island population split into two smaller, equal-sized populations when a river formed across the middle of the island. now two new species, a1 and a2, have evolved on the island. they have replaced the population from which they were derived.
Phylogenetics is the study of populations that have evolved over time. The evolutionary growth of an organism or of a generic group of organisms is referred to as phylogeny.
A phylogenetic tree, or tree diagram that shows how one taxon is directly or distantly connected to another taxon, is used to represent the evolutionary relationships. Phylogenetics evaluates anatomical or molecular traits and searches for patterns of relatedness. In order to demonstrate the evolutionary links between the various organisms, phylogenetic trees can be thought of as the physical representation of these ideas. Phylogenetic classification methods arrange species or other groupings in ways that correspond to how we understand how they descended from a common ancestor.
According to the supplied statement, rodents were able to attain identical population level after two million years, which can be explained using the theory of phylogeny.

What is the major difference between positive and negative feedback A positive feedback causes to continue of negative feedback cause it to stop or start B positive feedback results in temperature increases while negative feedback results in temperature decreases C positive feedback stimulates body system so while negative feedback shuts down body systems D positive feedback is controlled by external factors while negative feedback is controlled by internal factors
Answer:
A positive feedback causes to continue of negative feedback cause it to stop or start
Explanation:
A positive feedback occurs to help increase the output or increase the changes. While a negative feedback occurs to decrease or reduce the output or decrease the change. A positive feedback amplifies the results of any reaction to make the reaction more quickly and the negative feedback results in a reaction to reduce the system to its original state or stable state. Thus a positive feedback occurs to continue while negative feedback causes it to stop or to start.
Fermentation does not produce ATP. Why is fermentation such an important process in cells
Answer:
In humans we go through Lactic Acid Fermination
Explanation:
It is important because after glycolysis we have the elctron carrier NAD+ reduced to NADH and we cant continue glycolysis until we have NADH back to NAD+ so all lactic acid fermintation does it removed the electron and allow glycolysis to continue. It should be noted that fermintation occurs when there is no oxygen / not enough to continue cellular respiration so we rely on glycolysis to produce very little ATP while oxygen is replenished,

Explanation:
Widow's peak is a dominant trait (W). Tongue-rolling is a dominant trait (T). Two people who are heterozygous for both traits (widow's peak, tong-roller) get married and have children. Complete the Punnett square to show the parents the probabilities for each child, then answer the question that follows.
What is the probability that the parents will have a child without a widow's peak and unable to roll his tongue?
Group of answer choices
3/16
9/16
0/16
1/16
Answer:
The correct answers are -
A. 1) WWTt 2) WWTt 3)WwTt 4)wwTT
B. 1/16
Explanation:
We know that each gene have minimum two alleles or forms of the gene one is dominant and the other is recessive. So, it is given that W is dominant trait that represents widow's peak so the recessive allele would be w, similarly for the tongue-rolling trait dominant is T n recessive would be t.
So the dihybrid cross of heterozygous parents for both is shown in the punnet square given which lack few possibilities that can easily be carried out by the gametes mention there that are
1. WWTt by WT and Wt gamets
2. WWTt by WT and Wt
3)WwTt by Wt and wT
4)wwTT by wT and wT
And the possibility of a child without a widow's peak and unable to roll his tongue would be possible only if the alleles are recessive for the both trait which is one out of 16 in punnet square thus the possibility would be - 1/16

What two characteristics are useful for supporting the photosynthetic mode of energy generation found in euglenids?.
Answer:
An eyespot ( or photoreceptor) and a flagellum are useful for supporting the photosynthetic mode of energy generation found in euglenids
Explanation:
What use does the eyespot serve in euglena?
Near the reservoir, one can observe an eyespot on a euglena's anterior end. It can sense light. This supports euglena in locating sunny areas where they may capture sunlight for food preparation.
Euglena has two flagella one flagellum is very short and can not be seen clearly while the second one is large and can be observed. Flagella help euglena in locomotion or movement purposes and also in sensing environment. Flagella also help euglena in photosynthesis. While Euglena uses its flagellum to walk about in looking for food at night, Euglena contains chloroplasts and can do photosynthesis during the day.

cellular flice-inhibitory protein (cflip) isoforms block cd95- and trail death receptor-induced gene induction irrespective of processing of caspase-8 or cflip in the death-inducing signaling complex.
Death receptors (SDRs) result in apoptosis however additionally stimulate proinflammatory "non-apoptotic" signaling (e.g. NF-κB and mitogen-activated protein kinase (MAPK) activation) and inhibit awesome steps of DR-activated maturation of procaspase-8. To take a look at whether or not isoforms of cellular FLIP (cFLIP) or its cleavage products differentially regulate DR signaling, we mounted HaCaT cells expressing cFLIP(S), cFLIP(L), or mutants of cFLIP(L) (cFLIP(D376N) and cFLIP(p43)). cFLIP editions blocked TRAIL- and CD95L-induced apoptosis, but the cleavage pattern of caspase-8 in the dying inducing signaling complicated was different: cFLIP(L) brought on the processing of caspase-8 to the p43/41 fragments irrespective of cFLIP cleavage. cFLIP(S) or cFLIP(p43) blocked procaspase-8 cleavage. Analyzing non-apoptotic signaling pathways, we found that TRAIL and CD95L activate JNK and p38 within 15 min. cFLIP variations and exclusive caspase inhibitors blocked late demise ligand-induced JNK or p38 MAPK activation suggesting that these responses are secondary to mobile death. cFLIP isoforms/mutants also blocked dying ligand-mediated gene induction of CXCL-8 (IL-8). Knockdown of caspase-8 completely suppressed apoptotic and non-apoptotic signaling. Knockdown of cFLIP isoforms in most important human keratinocytes improved CD95L- and TRAIL-induced NF-κB activation, and JNK and p38 activation, underscoring the regulatory position of cFLIP for these DR-mediated signals. Whereas the presence of caspase-8 is fundamental for apoptotic and non-apoptotic signaling, cFLIP isoforms are strong inhibitors of TRAIL- and CD95L-induced apoptosis, NF-κB activation, and the late JNK and p38 MAPK activation. cFLIP-mediated inhibition of CD95 and TRAIL DR could be of necessary importance for the duration of keratinocyte skin carcinogenesis and the activation of innate and/or adaptive immune responses induced using DR activation in the skin.

protoporphyrin ix fluorescence and photobleaching during interstitial photodynamic therapy of malignant gliomas for early treatment prognosis
Prior to therapy, a high PpIX fluorescence was observed in three patients; however, after iPDT, this fluorescence was entirely photobleached. These patients' viable tumor sections had high PpIX concentrations (mean PpIX uptake per tumor: 1.4-3.0 M).
Briefing:However, no or just minimal PpIX uptake (0-0.6 M) could be seen in the remaining two cases. Strong PpIX uptake patients demonstrated therapeutic response and long-term clinical stabilization (no progression at 29, 30, and 36 months); the remaining two patients experienced early treatment failure (death after 3 and 9 months).
Describe fluorescence:Two steps make up the chemical process of fluorescence first, a chemical fluorophore such a protein or carotenoid absorbs shorter-wavelength light (excitation), and then some of the absorbed energy is released as longer-wavelength light (emission).
