Individual amoebae of the slime mold Dictyostelium discoideum aggregate to form a spore-producing fruiting body. Cheaters make spores, but do not contribute to the stalk. Since many more spores with cheating genotypes are dispersed, they have higher fitness. Why does directional selection not lead to fixation of the cheater genotype
Answer:
It is an example of frequency-dependent selection. Due to several cheaters in the population, the fruiting body's stalk is not made properly. So, all individuals have lesser fitness.
Explanation:
Natural selection:
The population contains both superior as well as an inferior organism where natural resources are limiting so it will cause competition between organisms. As a result of competition, it will select superiors, and inferiors are deleted and they are given reproductive advantages. Due to this reproductive advantage new population emerges. It is more suitable for the environment.
Natural selection divides into three parts that are directional, disruptive, and stabilizing selection.
The given question is the example of frequency-dependent selection. Due to several cheaters in the population, the fruiting body's stalk is not made properly. So, all individuals have lesser fitness. Directional selection will not lead to fixation of cheater genotype. This is because cheating can be controlled through high relatedness in social groups, resulting from kin discrimination.
It is controlled through positive pleiotropy, where the cooperation gene has an additional vital function. Cheating will be controlled if stalk vs. spore is a result of environmental, not genetic factors. An example, spore fate can be a result of the position in the mitotic cell cycle.

Does negative feedback stop or speed up the release of hormones?
Explanation:
Hormone production and release are primarily controlled by negative feedback. In negative feedback systems, a stimulus causes the release of a substance whose effects then inhibit further release. In this way, the concentration of hormones in blood is maintained within a narrow range.
Descibe a structural adaptation for obtaining food of a mammalian predator carnivore.
Answer:
Carnivores have biological adaptations that help them hunt. Carnivorous mammals such as wolves have strong jaws and long, sharp teeth that help them grab and rip apart their prey. Plant-eaters, on the other hand, usually have big molars that help them grind up leaves and grasses.

Explanation:
Imagine that you wish to compare two different diets that will be fed to tadpoles raised in a lab. One diet is a meat-based fish food, and the other is the traditional diet of boiled lettuce. You want to see if the meat-based diet will be associated with an increase in the average weight of the tadpoles. In your experiment you keep all other factors, such as tadpole density per pan, temperature, pH, and the amount of food the same. The only difference between your control and experimental groups is the type of food the tadpoles receive.
Which is a good hypothesis for this tadpole experiment?
A. Tadpoles will be larger if the ph is higher.
B. Tadpole size will be unpredictable if fed a meat-based diet.
C. Tadpoles will be larger if fed a meat-based diet.
D. Tadpoles fed a meat-based diet will be bigger , but only in a tank with low numbers.
Answer:
The correct answer is - C. Tadpoles will be larger if fed a meat-based diet.
Explanation:
In this experiment, it is observed that how the change in the type of diet if meat diet is internalized how the average weight of tadpoles increase comparatively than other types of diet.
In this experiment, pH remains the same so that can there would be no effect on this by a change in pH can be established by this experiment. The dependent variable is the increase in size so the correct hypothesis will be - C.

student set up an experiment using a Visking bag containing concentrated sugar solution. Visking tubing is permeable to water but not to sugar. Figure A, shows what the bag looked like at the start and figure B shows the bag after one hour.Explain why the bag has changed its shape after one hour. Use the term “water potential” in your explanation (2).
Water moved inside the bag in response to the water potential causing a change in the size of the bag.
What is water potential?The term term water potential refers to the energy required to transport a small amount of water across a boundary.
We must note that water potential is responsible for the movement of water into the bag resulting in its change of shape as shown. Water moved inside the bag in response to this potential.

The bag changed its shape because water moved from the side with a higher water potential to the bag interior, where there is a lower water potential.
What is osmosis?
Osmosis is the simple passive transport of water molecules that occurs when two dilutions of different concentrations -in this example, the interior of the Visking bag and water- are separated by a semipermeable membrane.
The membrane allows the pass of water but not solute (sugar). Hence, water can move from the most diluted side to the less diluted one. This is, from the side of the membrane with higher water potential, to the side with lower water potential.
Let us remember that the water potential is the potential energy in a mass of water. Among other factors, it depends on solute concentration,
Most diluted side ⇒ higher water potentialMost concentrated side ⇒ lower water potentialIn the exposed example, water tends to go from the hypotonic solution (higher water potential) to the bag interior (lower water potential) and keeps doing so until concentrations are equal in the bag interior and exterior.
The bag has changed its shape because as water moved, the bag began to enlarge and became bigger-sized.

the diagram shows the measurements of two fish. the difference in length between fish a and b is?
Answer:
2 cm
Explanation:
The difference in length between fish a and b is 2 cm. Thus, option A is correct.
What is measurement?
Distance is a physical quantity which is measured in meter. If a man travel then it is measured in meters that defines that how much he travel from one point to another point for all these type of things we use to measure distance.
Centimeter is also a physical quantity which is use to measure distance. 1 centimeter is equal to 0.01 meter and 1 centimeter is equal to 0.00001 kilometer.the kilometer is large quantity to measure distance while centimeter is smaller quantity to measure distance.
Kilometer is also a physical quantity which use to measure the distance 1 kilometer is equal to 1000 mtr and 1 kilometer is equal to 100000 centimeter.
For above conclusion, we easily states that the kilometer is large quantity to measure distance while centimeter is smaller quantity to measure distance. Centimeter is also a physical quantity which is use to measure distance. 1 centimeter is equal to 0.01 meter and 1 centimeter is equal to 0.00001 kilometer.
