many species of animals carry an allele for albinism (lack of pigmentation). Albinos are usually pale or white in color. explain why the allele for albinism is present at la lower frequency than the allele for having pigments. what conditions would be necessary for the albino allele to be more frequent?
Answer: breeding an albino with an albino and let the babies lose and repeat
Explanation:
The allele for albinism is present at a lower frequency because it is not adaptive for most of the environments where humans live.
What is an allele?An allele is a gene variant that confers a certain fitness to an individual depending on the environment where this organism lives.
Adaptive alleles are in high frequency because they confer an adaptive advantage.Non-adaptive alleles are present in low frequency because they do not confer an advantage.In conclusion, the allele for albinism is present at a lower frequency because it is not adaptive.

What are they most likely to observe about the stems after turning the jar on its side?
A: Grow sideways in their new position
B: Start growing downward in their new position
C: Stop growing more than they have already grown
D: Start growing upward in their new position
Why do organisms with one color produce few offspring than those with multiple colors?
Answer:
atural selection can cause microevolution (change in allele frequencies), with fitness-increasing alleles becoming more common in the population.
Fitness is a measure of reproductive success (how many offspring an organism leaves in the next generation, relative to others in the group).
Natural selection can act on traits determined by alternative alleles of a single gene, or on polygenic traits (traits determined by many genes).
Natural selection on traits determined by multiple genes may take the form of stabilizing selection, directional selection, or disruptive selection.

Answer: I think it's A
Explanation: Butterflies, moths, beetles, flies and bees have complete metamorphosis. The young (called a larva instead of a nymph) is very different from the adults. It also usually eats different types of food. There are four stages in the metamorphosis of butterflies and moths: egg, larva, pupa, and adult.

1. Describe the flow
of energy in a
marine food web.
Include at least 5
organisms.
2. Describe how
removing an
organism from a
food web can
impact the entire
ecosystem.
Answer:
1. A food chain is a single pathway connecting a producer with several levels of consumers. In a typical marine food chain, dinoflagellates convert energy from sunlight into food through photosynthesis and store it in their tissues.
2. They would starve and die unless they could move to another habitat. All the other animals in the food web would die too, because their food supplies would have gone. The populations of the consumers would fall as the population of the producer fell.
have a good day!
The flow of energy in a marine food web include the following:
Plankton⇒shrimp⇒ salmon⇒ seals⇒ whales
What is a food web?A food web comprises of food chains which are interconnected and also
explains the flow of energy between organisms in the ecosystem.
In the marine ecosystem, the plankton which are plants are the primary
producers while the whales are the tertiary/quaternary consumers as they
are at the top of the web.
Removing an organism from a food web can impact the entire ecosystem
by reducing the number of organisms and options available for food. It can
increase or decrease the population of organisms which they have direct
relationship with.

What is the origin of the energy that all organisms need to carry out life functions?
A. food
B. producers
C. plants
D. the Sun
Answer:
D. The Sun
Explanation:
The Sun is the major source of energy for organisms and the ecosystems of which they are a part. This process begins the flow of energy through almost all food webs. Food is sunshine stored in chemical form. Organisms use the stored energy in food to fuel all living processes.
Explain why a food web is a more realistic model of energy flow than a food chain.
No links or jibberish!
Answer:Las redes tróficas consisten de varias cadenas alimentarias interconectadas y son una representación más realista de las relaciones de consumo en los ecosistemas. La transferencia de energía entre niveles tróficos es ineficiente, con una eficiencia típica de alrededor del 10%.
Explanation:
Answer:
Food chains only show one path by which energy can move through an ecosystem. Because most organisms eat a variety of things, they are part of many food chains. A food web shows the interconnected food chains in an ecosystem and the multiple paths through which energy can move, which is why it is a more realistic model for showing energy flow.

The Nervous System is one of the first systems to develop during the embryonic period. Why do you think this is?
The process of neurulation, which takes place between weeks three following conception, allows the embryo to form the components that will one day become the nervous system. It's important to regulate body functions.
What is embryonic nervous system?The neural crest gives rise to the development of structures in the periphery. At this stage, the early nervous system resembles nothing more than a straightforward tube. It begins from the front of the embryo and continues all the way around to the back. Beginning at day 25, the anterior end will develop into the brain, while the posterior portion will develop into the spinal cord.
The brain is the organ that is responsible for controlling every function of the body. The brain is connected to the rest of the body through the spinal cord, which travels down the back. It contains nerves that are similar to threads and branch out to every organ and area of the body. Messages are transmitted to and from the brain via this network of nerves, which connects the brain to various regions of the body.
