Answer: Norrie disease almost entirely affects males.
Explanation: Due to the X-linked recessive pattern of inheritance, Norrie disease affects almost entirely males. Only in very rare cases, females have been diagnosed with Norrie disease; cases of symptomatic female carriers have been reported.
A group of mice becomes separated by the formation of a river. Over time, the northern mice became smaller and whiter, while the southern mice became larger and browner. This is an example of:
Answer Choices:
-divergence
-homology
-gigantification
-industrial melanism
This is an example of gigantification.
What is meant by evolution?
Evolution is the change in the features of a species over several generations and depends on the procedure of natural selection. The theory of evolution is based on the idea that all species are related and gradually change over time.
Thus, this is an example of gigantification.

According to the food web shown above, what is the relationship between the wheat, the grasshopper, the frog, and the snake?
A. The snake directly consumes the frog, the grasshopper, and the wheat.
B. The grasshopper consumes the wheat, and the snake consumes the frog, but there is no connection between the other organisms.
C. The wheat is consumed by the grasshopper, the grasshopper is consumed by the frog, and the frog is consumed by the snake.
D. The wheat is directly consumed by both the grasshopper and the frog, and the frog and the grasshopper are directly consumed by the snake.
Answer:
The wheat is consumed by the grasshopper, the grasshopper is consumed by the frog, and the frog is consumed by the snake.
Explanation:
A food web is a model that can be used to better understand the feeding relationships between organisms in an ecosystem. Arrows in a food web start at a food source and end with the consumer.
So, in the food web shown in the question, the wheat is consumed by the grasshopper, the grasshopper is consumed by the frog, and the frog is consumed by the snake.

A species of fish is unintentionally introduced into a marine ecosystem. The species has a similar diet to an existing fish species, creating competition for food. Which of the following must occur for the existing species to be more resilient in the environment? (3 points)
Individuals within the existing species' population must evolve traits that provide a survival advantage.
Individuals should have less genetic diversity to become more similar and evolve in the same direction.
Natural variations in phenotype must be present in the existing species' population.
The existing species must reduce its rate of reproduction to produce only the most fit offspring.

Many plants have the ability to respond to herbivores. Some plants produce substances
which are distasteful or toxic in response to an herbivore attack. Which of these is the LEAST correction description of the plant system interactions involved?
A. Carbon dioxide diffuses through stoma into leaf tissues, where it is fixed into organic compounds
which may serve as building blocks for chemical defenses.
B. Root systems obtain water and key minerals from the soil where they are transported to the affected site.
C. Shoot systems carry carbon dioxide, water and nutrients from leaves directly to the affected
plant part, where chemical defense molecules are produced.
D. Chemicals found in a herbivore's saliva trigger chemical messengers which trigger production of
defense molecules
Answer:
I'm pretty sure that the answer is d :)
Explanation:
<3
Answer:
yeah
Explanation:
Mechanical Defenses
The first line of defense in plants is an intact and impenetrable barrier composed of bark and a waxy cuticle. Both protect plants against herbivores. Other adaptations against herbivores include hard shells, thorns (modified branches), and spines (modified leaves). They discourage animals by causing physical damage or by inducing rashes and allergic reactions. Some Acacia tree species have developed mutualistic relationships with ant colonies: they offer the ants shelter in their hollow thorns in exchange for the ants’ defense of the tree’s leaves.

Explanation:
So the capital letter is the dominant trait, and the lowercase letter is recessive. The capital dominant trait will always overpower the lowercase recessive trait. So the only way the recessive trait can be seen is if there are two together. So... if R is white fur and r is brown fur...
RR would show the dominant trait of white fur
Rr would show the dominant trait of white fur
rr would show the recessive trait of brown fur

How does artificial selection differ from natural selection? Choose all that apply.
O During artificial selection, the mating pairs are selected by humans, not the organisms.
O The outcomes of artificial selection are predictable.
O Artificial selection requires variety in a population.
O Artificial selection does not help a population adapt to its environment.
Answer:
All answers should be selected.
Explanation:
Artificial selection means humans select the mating pairs which makes the outcomes predictable. Variety is required because it is how humans can "customize" the traits of an organism. However, it does not help a population adapt to its environment because these traits are made for human satisfaction, not the survival of an organism.

what are some non examples of negative feedback?
Answer: (EXAMPLES). Human body temperature - The hypothalamus of a human reacts to temperature fluctuations and responds accordingly. If the temperature drops, the body shivers to bring up the temperature and if it is too warm, the body will sweat to cool down due to evaporation.
Human blood pressure - When blood pressure increases, signals are sent to the brain from the blood vessels. Signals are sent to the heart from the brain, and heart rate slows down, thus helping blood pressure to return to normal.
Human metabolism - When a human is hungry, metabolism slows down to conserve energy and allows the human to continue living with less food.
Regulation of blood sugar in humans - When blood sugar rises, insulin sends a signal to the liver, muscles, and other cells to store the excess glucose. Some is stored as body fat, and other glucose is stored as glycogen in the liver and muscles.
Production of human red blood cells (erythropoiesis) - A decrease in oxygen is detected by the kidneys and they secrete erythropoietin. This hormone stimulates the production of red blood cells.
Explanation: Since we all know, A negative feedback loop is a reaction that causes a decrease in function. It occurs in response to some kind of stimulus. Often, it causes the output of a system to be lessened; so, the feedback tends to stabilize the system. This can be referred to as homeostasis, as in biology, or equilibrium, as in mechanics.

Explanation:
Cellular respiration is a collection of three unique metabolic pathways: glycolysis, the citric acid cycle, and the electron transport chain. ... In order to move from glycolysis to the citric acid cycle, pyruvate molecules (the output of glycolysis) must be oxidized in a process called pyruvate oxidation.
