Answer:
Carrying capacity is the maximum amount of organisms that an ecosystem can support. So to ensure that an ecosystem stays balanced the population needs to be under the carrying capacity. If it is not, then organisms will begin to die until the ecosystem is balanced again. The carrying capacity is related to limiting factors as such food, space, water, and sunlight. There are limited amounts of all of these, and they can only support so many plants and animals.
Answer:
For there to be a balance ecosystem, there must be a balance between a population in which it should not exceed the carrying capacity, leading to the destruction of the tier of food below them, neither should there be too later, leading to the destruction of the food tier above them. When the population is able to not only maintain but also adapt to the changing carrying capacity, then the population would continue to live on.
What happens if they fail to stay within the carrying capacity? Think of it in two ways:
1) The fall short of the minimum carrying capacity. Assuming they are the only carnivores, then the amount of herbivores and omnivores per population would explode, leading to overgrazing and the destruction of the ecosystem from the bottom up.
2) If the carnivores exceed the maximum carrying capacity, there may be a high chance of wiping out a certain species or overhunting them, resulting in a collapse both on the top from starvation, but also at the base from excessive population growth due to having no second tier.
Meeting the requirement for carrying capacity while not exceeding it is necessary to allow for each tier within the ecosystem to stay in the level that they should, in that they are well fed and maintaining the normal growth levels, while not overpopulating and destroying the ecosystem from the inside out.

Imagine carefully weighing a metal can, leaving it out in the rain for weeks and weeks until it was very rusted, and then carefully weighing it again. Would the can be heavier or lighter after it was rusted?
Answer:
The answer would be heavier, though it depends upon the type of metal. Rusting is essentially corrosion. Rust is often caused by a piece of metal getting soaked in water and then being exposed to oxygen. The rust will add more weight to the can so it becomes heavier.
Leaving out metal can in the rain for weeks and weeks until it was very rusted, and then if we carefully weighing it again it can be found that the can weighs more because the rust deposited on the metal can adds more weight.
What is rust?
Rust is referred to as an iron oxide, and a form of corrosion which is caused by a chemical reaction which affects masses of iron and steel.
Once formed, rust starts to eat away at the metal, forming a flaky, orange red coating which weakens the iron. It occurs when the metal reacts with oxygen and water.

Attached earlobes are a recessive trait in humans. In the tree below, people
with attached earlobes are shaded in. Which best describes the person
labeled X in the tree?
A. A female with no recessive alleles
B. A male with no recessive alleles
C. A male with one recessive allele
D. A female with one recessive allele
Answer:
It would be C
Explanation:
If you look at the tree you can see that one of the male's parents had the recessive allele, and one of the siblings has the ressive allele, the means the male could have the trait but isnt showing it.
A male with one recessive allele describes the person labeled X in the tree.
What is Recessive allele?
In terms of genetics, the term "recessive" describes the connection between an observed trait and the two inherited forms of a gene associated with that feature.
Each gene has two alleles that an individual inherits from each parent. When a characteristic is recessive, both of the (recessive) alleles of the gene that causes the trait must be present for the trait to manifest.
When there is only one copy of an allele, it has no effect at all. This is in contrast to a dominant trait, which can only be expressed when one of the two alleles is present.
Therefore, A male with one recessive allele describes the person labeled X in the tree.

1 trial
2. Suppose each trial equals 1,000 years. What is the half-life of Virtualium?

Male peacocks have large colorful tails that they spread in a fan shape to attract females during courtship. Peahens (female peacocks) are more likely to mate with males that have larger and more colorful tails. As a result, few peacocks have tails with dull coloring.
A male peacock.
Which concept is demonstrated by a decrease in dull coloring?
speciation
biodiversity
natural selection
variation
Answer:
C
Explanation:
The concept demonstrated by a decrease in dull coloring in male peacocks is natural selection.
What is natural selection?
Natural selection is the process by which organisms with favorable traits are more likely to survive and reproduce, passing those traits to the next generation. In the case of male peacocks, having large and colorful tails is a favorable trait because it increases the likelihood of attracting a mate and passing on their genes.
As a result, over time, more and more peacocks have developed larger and more colorful tails through natural selection. The decrease in dull coloring among male peacocks is an example of natural selection favoring a particular trait (large, colorful tails) that confers a reproductive advantage, leading to a change in the population over time. Therefore, the correct concept demonstrated by a decrease in dull coloring is natural selection.

Las células en los tejidos epiteliales están fuertemente unidas a la lámina basal. ¿Qué tipo de proteínas están involucradas en este tipo de unión célula-matriz?
Answer:
integrinas y lamininas
Explanation:
Las integrinas son glucoproteínas implicadas en el anclaje de las células epiteliales a la matriz extracelular. Las células epiteliales tienen en su base proteínas integrinas que se unen a otras proteínas tales como vitronectina, fibronectina, colágeno y laminina. De este modo, las integrinas se asocian con lamininas de la lámina basal. Las lamininas son otra clase de glucoproteínas las cuales conforman la lámina basal y contienen sitios de unión para integrinas. A partir de esta asociación las células epiteliales pueden adherirse a la membrana basal y mantener su orientación dentro de un tejido. Estas uniones son fundamentales para que las células epiteliales puedan soportar fuerzas y son críticas durante el desarrollo apropiado (ontogenia) del organismo.
