8. How did the Grants test their hypothesis that differences in birds' songs can keep finches
from breeding with members of other species?
a. They watched which birds were mating with each other and listened for the songs the
birds were singing.
b. They recorded birds singing on the island of Daphne Major for an entire breeding
season to see which type of song was used more often by each species.
c. They played the songs of medium ground finches and cactus finches through a
loudspeaker at different times, when individuals from both species were present, to see which
species responded to each song,
d. They played the song of the medium ground finch to medium ground finch males
through a loudspeaker to see if they would respond; they then played the song of the cactus
finch to cactus finch males to see if they would respond.
9. Explain the evidence presented in the film for your answer in question #8 above.
a. Males only came to the loudspeaker when the song of their own species was being played.
b. The type of song used more often during the breeding season was also the song sung by the
most abundant species.
c. During mating, birds sang the song of their own species.
Answer:
The correct answer is -
8. They played the songs of medium ground finches and cactus finches through a loudspeaker at different times, when individuals from both species were present, to see which species responded to each song.
9. Males only came to the loudspeaker when the song of their own species was being played.
Explanation:
To test the hypothesis that differences in finches song they sing keep these finches to breeding from other members of finches, Grant should play the different songs of both medium ground finches and cactus finches one by one in loudspeaker and see what members of finches respond on what song.
It will show that cactus fiches breed only on their songs and medium ground finches on their song if the hypothesis is true. Male of each species respond to their songs only and not on other song played on loudspeaker

Help! ASAP, this is due tomorrow and I’m struggling as this isn’t what they taught us. The question is: Explain why the bacteria shown (E. coli) have a second membrane outside the
peptidoglycan.
The second membrane protects e.coli (Gram-negative bacteria) against a harsh environment.
The outer membrane indirectly helps stabilize the inner membrane as peptidoglycan layer in Gram-negative bacteria is relatively thin than gram positive bacteria ( they have multilayer pepdtidoglycan )
The second membrane called the outer membrane helps in stabilizing bacterial cells as peptidoglycan is thinner in E.coli cells.
What is an outer membrane?A double membrane is present in gram-negative bacteria, and it provides both protection and nutrition for survival.
The outer of these membranes is known as the outer membrane (OM), and it comprises a variety of completely integrated membrane proteins that carry out a number of crucial cellular processes, including nutrition absorption, cell adhesion, cell signaling, and waste export.
Several of these outer membrane proteins (OMPs) for pathogenic strains also function as virulence factors for nutrition scavenging and evading host defense systems. OMPs are distinct from other membrane proteins in that they have a -barrel fold and can vary in size from 8 to 26 strands while still carrying out a wide range of cellular activities.
Although these OMPs play crucial roles in cell viability and pathogenicity, the precise mechanism behind their synthesis into the OM is still largely unclear.
However, during the past ten years, there has been a tremendous advancement in our understanding of the routes and processes that shape a nascent polypeptide into a functioning OMP within the OM.
Here, we will go through a few of these new discoveries that have improved our knowledge of how Gram-negative bacteria produce OMPs, from their production in the cytoplasm to their folding and insertion into the OM.
Therefore, the second membrane called the outer membrane helps in stabilizing bacterial cells as peptidoglycan is thinner in E.coli cells.

Consider two pure-breeding lines of grapes, P1 and P2. The average diameter of P1 grapes is 1.2 cm and the variance is 0.30 cm2. The average diameter of P2 grapes is 1.6 cm and the variance is 0.56 cm2. The two pure-breeding lines are crossed to produce F1 progeny. Based on this description, which of the following statements is false?
a) VG for F1 is > 0
b) VP for P1 < VG for P2
c) VE for F1 is > 0
d) VG for P1 = 0
e) VG for P2 = 0
Answer:
a)
Explanation:
From the given information:
The avg diameters:
For P1 grapes =1.2 cm
For P2 grapes = 1.6 cm
Their vairance is also given as follows:
For P1 = 0.30 cm²
For P2 = 0.56 cm²
Recall that:
the phenotypic variance VP = genetic variance (VG) + environmental variance VE
As stated that P1 and P2 lines are pure breeding lines, which means that the diameter of the seed in F1 was around halfway between the two parents' and the difference in the F1 was close to the parents'.
This implies that, provided the parent lines exist as pure breeding;
The genetic variation would be absent, indicating that VG is zero.
∴
VP = VE and VG = 0
Now, averaging the results of two pure breeding lines, we have:
[tex]V_E = \Big (\dfrac{0.30 + 0.56}{2} \Big) \\ \\ V_E = \dfrac{0.86}{2} \\ \\ V_E = 0.43 \ cm^2[/tex]
The formula used in estimating F1 genetic variance can be expressed as:
VP = VG + VE
Recall that
VE = VP = 0.43 cm²
∴
0.43 = VG + 0.43
VG = 0.43 - 0.43
VG = 0
Thus, The statement that is false is in Option a.
VG for F1 is > 0
Under normal conditions, hyperventilation will eventually lead to unconsciousness because Group of answer choices blood pH drops significantly. it leads to respiratory alkalosis. there's too much carbon dioxide in the blood. Two of the answers are correct. very high PO2 leads to an excess of ATP production and neural inhibition.
Answer:
The correct answer is ''it leads to respiratory alkalosis.''
Explanation:
Respiratory alkalosis is defined by pH values> 7.45, and is characterized by an increase in pH and a decrease in pCO2. The most frequent cause is alveolar hyperventilation. Alveolar hyperventilation causes respiratory alkalosis, presenting a decrease in ionic calcium and in some cases tetany. To compensate for this increase in pH, renal HCO3 excretion is increased, but this process requires 24-48 hours. Respiratory alkalosis - primary or compensatory - is defined by hypocapnia, a finding that involves alveolar hypoventilation. The symptoms of acute respiratory alkalosis, the "hyperventilation syndrome," vary only in intensity from those of any alkalosis - most notably disturbances in neuromuscular function (eg, paresthesias, tetany, tremor). A constellation of symptoms have been described with respiratory alkalosis, including increased intracranial pressure, decreased consciousness, tachycardia, hypertension, carpopedal spasm, anxiety, dizziness, and a feeling of vertigo.

b) dolphins and bats share a common ancestor that is more recent than the one shared with birds
c) amino acid sequences for the cytochrome C analysis of these two species will also be similar
d) the dolphin in the back diverge under different selective pressures, which accounts for their differences
e) embryological comparisons of these two species will show homologies of each other than bats have with birds
Answer:
D. the dolphin in the back diverge under different selective pressures, which accounts for their difference
Explanation:
I hope this is helps you
Dolphins and bats share a common ancestor that is more recent than the one shared with birds.
Homologous bodiesHomologous organs are those that may or may not perform the same function, but have the same basic structure and the same embryonic development. This means, therefore, that individuals who have these organs have shared ancestry.
Whit this information, we can conclude that dolphins and bats share a common ancestor that is more recent than the one shared with birds.

Cree usted que las diferencias anatómicas entre los individuos de la humanidad surgieron como respuestas a acondicionamientos ambientales
Answer:
no, la selección natural opera sobre los fenotipos seleccionando aquellos que mejor se adaptan a su medio ambiente. En consecuencia, el medio ambiente actúa como agente selectivo pero no es el disparador de los cambios fenotípicos/anatómicos
Explanation:
Jean-Baptiste de Lamarck fue un naturalista francés el cual propuso que los individuos se adaptaban para sobrevivir a su ambiente, y que estos cambios fenotípicos/anatómicos eran transmitidos a la progenie. Por otra parte, Darwin propuso la teoría de la evolución por selección natural la cual establece que aquellos individuos mejor adaptados a su ambiente tiene más chance de sobrevivir y reproducirse, y con lo cual también tienen más chances de trasmitir sus rasgos anatómicos/fenotípicos a la siguiente generación. Hoy en día, la teoría de la evolución de Darwin es ampliamente aceptada por la comunidad científica y permite explicar la variación existente entre individuos. De este modo, de acuerdo a la pregunta planteada, las diferencias anatómicas/fenotípicas entre los individuos de la humanidad no surgieron como respuesta al acondicionamiento ambiental: el ambiente funciona como agente selectivo, seleccionado aquellos individuos mejor adaptados a sobrevivir en cada ambiente en particular.

Ian is an 18-year-old gymnast training at a private gym with many other male and female gymnasts. he is competing at an advanced level and is likely to make the next Olympic team. Lately, he has found that some of his balance and strength moves on the rings and parallel bars have become more difficult. He has gone through a bit of a growth spurt and gained approximately 5 pounds over the last year. He suspects the weight gain is causing his performance difficulties. He decides to try a weight-loss program that will help him lose weight before his next big competition in 6 weeks. He is not sure how many calories to consume and therefore arbitrarily decides to eat 1,500 calories per day.
1. Which assessments are required to determine whether Ian needs to lose weight?
2. What type of diet and exercise plan would you recommend for Ian?
3. What additional concerns do you have for Ian's health and sport performance?
Answer:
Explanation:
(1.)
Assessments needed to reduce Ian’s body weight:
A weight-loss program should allow the loss of weight should be fat loss, and the increase of weight should be body muscle mass. Weight reduction should be accompanied by an acceptable exercise regimen (both strength and conditioning). A well-balanced diet with sufficient energy (calories), carbohydrates, protein, and fat should be part of every weight-loss regimen. Excessive exercise resulted in weight loss. Using anorexic medications, laxatives, insulin, diet tablets, stimulants, diuretics, dietary products, or any lawful or illicit drugs and/or nicotine should be banned at all levels.
(2)
type of Diet:
Every day, Ian must eat three meals and just a snack. A fiber-rich cereal with skim milk and fresh fruit can be a better way to start the day.
After that, have a bologna sandwich on the whole bread with fruit or a big vegetable-rich salad together with a small turkey sandwich in addition to a cup of skim milk for lunch.
Poultry hen should be served with potatoes (baked), mixed vegetables, and skim milk for dinner. An early workout snack of a small butter muffin or yogurt combined with cereal should also be included.
Exercise Plan:
i) Bodyweight fat recovery can be supported by proper and secure aerobic activity.
ii) The right kind of aerobic exercise is extremely beneficial for weight loss.
3. Gymnastics is a visually appealing discipline that necessitates speed, strength, and coordination. Most high-level gymnasts eat less than the recommended amount of calories and certain nutrients for their age and training load, according to dietary tests. Young gymnasts, in particular, must absorb enough energy and nutrients to satisfy the demands of growth, exercise, performance, and tissue conservation. Poor energy supply, disordered eating habits, and eating disorders are all factors that can damage a gymnast's long and short-term health. Some gymnasts cross the line into extreme, treatable eating disorders by dieting and using infective weight-loss strategies.
In light of these considerations, Ian should pay attention to his health and diet. Ian should limit his consumption of added sugar intake and increase his fiber intake to help him achieve his body fat targets. Gymnasts can consume at least 1.4–1.8 grams of carbohydrates each pound (3–4 g/kg) per day. Increased protein consumption helps to reduce the amount of muscle lost over a weight-loss cycle. Per day, gymnasts can eat 0.8–1.2 g/lb (1.8–2.7 g/kg) of protein.
Ian would be able to shed weight and prevent an eating disorder in this manner.
