Question:
A male cardinal's red color is an example of a trait affected by natural selection. The females of the species choose mates based on the vibrant colors of the males' feathers. If females begin using different criteria than feather color when they choose mates, what would most likely happen to the color of the male cardinals over time?
Answer:
Feather color loses importance in sexual selection and becomes disadvantageous for males. There is a decrease in red color variation among males.
Explanation:
In cardinal species, females choose males to mate according to their vibrant red color. The redder the male is, the better genetic charge it has, and the better choice for mating it becomes.
Red feather color is a trait that reflects the genetic quality of males. So individuals with the most vibrant red color express better capabilities of finding food, competing for resources, competing for males, among others, are the best option to mate and to ensure successful offspring.
The brightest or most vibrant males are in red, the better chances they have to mate and pass their genes to the following generations. So the organism spends energy and resources to produce more vibrant colors to enhance mating chances.
However, if females begin using different criteria than feather color when they choose mates, color production stops making sense. What is even more, it becomes more disadvantageous for males because females do not use color for their choices, males spend energy when producing it, and the redder the males are, the more chances to be predated they have. So basically, males´ feather color loses importance. The selection pressure in males turns to the evolution of another trait. The shade variation of red feathers will decrease over time.
7. A student astronomer went out and took photographs of the Moon that were several days apart.
Images that look like her photographs are shown above. The light part of the Moon appeared to get
smaller over time. Why did this happen?
a
Between the first photograph and the second photograph, the Moon moved farther away
from the sun so less sunlight reached the Moon's surface.
b
Between the first photograph and the second photograph, Earth moved so its shadow was
blocking more of the Moon so the student astronomer was able to see less of it.
с
Between the first photograph and the second photograph, the Moon rotated so that less of
the light-colored rock on the Moon's surface faced Earth.
d
Between the first photograph and the second photograph, the Moon moved so that the
student astronomer was able to see less of the half that faces the sun.

Answer:yh it is b
Explanation:
A student astronomer went out and took photographs of the moon that were several days apart, and this is because the moon moved so that the student astronomer was able to see less of the half that faces the sun, which is option d.
What is the significance of the moon revolution?The changing appearance of the moon over time is due to its changing position in its orbit around the earth, the light part of the moon appeared to shrink over time as the moon moved in its orbit, causing the illuminated part that faces the earth to diminish and the dark phase to appear.
Hence, a student astronomer went out and took photographs of the moon that were several days apart, and this is because the moon moved so that the student astronomer was able to see less of the half that faces the sun, which is option d.

Select the correct answer from each drop-down menu. Bile juices help in the breakdown of fats. An injury to the may cause a decrease in the production of bile juices. This decrease in bile juices may lead to decreased production of .
Answer:
Decreased production of energy.
Explanation:
Decrease in bile juices may lead to decreased production of energy from eating of food having fats because our body has no ability to absorb fat-soluble vitamins and fatty acids. Bile juices is responsible for the absorption of fat-soluble vitamins and fatty acids which is then transported to the cell for producing energy that is required by our body for different processes. Fats have more energy than carbohydrates and protein so if there is no bile juices are present so it break down does not occurs.

The populations of which organisms will most likely increase as a result of a disease that suddenly reduced the population of Texas horned lizards?
F Grasses and ants
G. Ants and grasshoppers
H Grasshoppers and Texas cottonmouths
J. Texas cottonmouths and red-shouldered hawks
Answer:
G
Explanation:
It just is
Texas horned lizards primarily feed on ants, so if their population is suddenly reduced due to disease, the populations of their prey (ants) will likely increase.
What will they lead to if the population growth declines ?This, in turn, can lead to an increase in the populations of other organisms that depend on ants for food, such as grasshoppers.
Texas horned lizards are known to feed primarily on ants, and as predators, they play an important role in regulating the populations of their prey. When the population of Texas horned lizards is reduced, the ant population can increase, as there are fewer predators consuming them. This increase in ant population can lead to an increase in the populations of other organisms that depend on ants for food, such as grasshoppers.
Grasshoppers are herbivores that feed on vegetation, but they also feed on ants and other small insects. When the population of ants increases due to the reduction in Texas horned lizard population, the population of grasshoppers may also increase as they have more food resources available.
In contrast, Texas cottonmouths and red-shouldered hawks do not directly depend on Texas horned lizards as a food source, so their populations are unlikely to be significantly affected by a reduction in the population of Texas horned lizards.
Therefore, the populations of grasshoppers and ants (option G) are most likely to increase as a result of a disease that suddenly reduces the population of Texas horned lizards.

Why are humans dependent on healthy ecosystems throughout the world?
Answer: Human health ultimately depends upon ecosystem products and services (such as availability of fresh water, food and fuel sources) which are requisite for good human health and productive livelihoods. Significant direct human health impacts can occur if ecosystem services are no longer adequate to meet social needs.
Explanation:
Humans are dependent on healthy ecosystems as they provide resources, regulate climate, purify water, control diseases, offer recreational and cultural values, and drive economic activities.
For a number of reasons, functioning ecosystems are essential to human existence. supplying resources Healthy ecosystems offer vital resources like food, fresh water, clean air, and building supplies like fibre and wood. These materials provide for our basic necessities and are essential to our survival.

Answer: Liquid: A liquid is a form of matter. It is settled between solid and gas. Liquid has an almost-fixed volume, but no set shape. Every small force makes a liquid change its shape by flowing. Because of that, gravity makes liquids always take the shape of the container. The molecules that make up the liquid can freely move among themselves.A gas consists of a large number of extremely small molecules which are exactly identical in all respects.

What do cells in the spongy mesophyll layer have that makes gas exchange easier?
Answer:
The spongy mesophyll cells are adapted for gas exchange. They are loosely-packed with large intercellular air spaces where gases can readily diffuse. They have fewer chloroplasts than palisade cells, so carry out less photosynthesis . When the plant is photosynthesising during the day, these features allow carbon dioxide to diffuse into the spongy mesophyll cells, and oxygen to diffuse out of them.
A heater provides heat to an area, but the temperature in the area stays about the same. What do you already know about this phenomena?
ANSWER: IT'S CALLED THE ZEROTH LAW OF THERMODYNAMICS
EXPLANATION:
The zeroth law of thermodynamics state that there's no heat transferred between two objects in thermal equilibrium (i.e having the same temperature). This phenomenon depicts that there's balance in the amount of temperature in all the three entities.
This phenomenon was credited to Sir Ralph Howard Fowler, a British physicist and astronomer during his lifetime.
A scientific paper by Carathéodory also added that when two systems S1 and S2 are made to reach equilibrium with a third system S3 under close thermal conditions, systems S1 and S2 are said to be in mutual equilibrium.
