What is a segmented worm?
Segmented worms have long tube-like bodies that are divided into segments.
They are the simplest organism with a true nervous system and blood contained in vessels.
They have a long digestive tube that runs down the length of the worm's inner body.
They can take in dissolved oxygen from the water through their skin.
Thus, a segmented worm has a nervous system, blood vessels, and a long digestive tube.

In a population of pea plants such as the one below, bees and other pollinators prefer to land on purple colored flowers. Over generations, more and more purple flowers successfully reproduce due to this pollinator preference. Which of the following statements accurately describes what is happening to the pea plants over time?
Question 2 options:
Natural selection causes evolution in the population of pea plants and leads to increased overall variation.
Natural selection causes evolution of individual pea plants and leads to increased overall variation.
Natural selection causes evolution in the population of pea plants and leads to an increase in favorable adaptations.
Natural selection causes evolution of individual pea plants and leads to an increase in favorable adaptations.
Answer:
Natural selection causes evolution in the population of pea plants and leads to an increase in favorable adaptations.
Explanation:
The flowers will evolve to keep that purple trait in order to continue their population growth, hence why it is not individual evolution but as a population. Also since the purple color is a favorable trait it will lead to an increase in favorable adaptations and will decrease variation.

18 The size of a mouse population in a natural
ecosystem tends to remain relatively constant due to
A. the cycling of energy.
B. the lack of natural predators.
C. the increased numbers of decomposers.
D. the carrying capacity of the environment.
Answer:
D- the carrying capacity of the environment.
Explanation:
The limiting factors also called as the carrying capacity of the environment keeps the size of a mouse population in a natural ecosystem constant. Therefore, option (D) is correct.
What is a limiting factor in a ecosystem?Limiting factors are physical, biological, and ecological conditions that:
(1) Limit the ecosystem's ability to sustain native plant and animal populations and to accommodate natural disturbances like floods;
(2) Limit the quality or availability of habitat that supports all life stages of native species; and
(3) Limit the ecosystem's ability to sustain the local tribal culture.
The only natural factor limiting the number of mice in the home is a scarcity of resources such as food. Therefore, The limiting factors also called as the carrying capacity of the environment keeps the size of a mouse population in a natural ecosystem constant.

how do homologous structures show common ancestry?
Answer:
Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species' relatedness.
Explanation:
The correct statement is C. They demonstrate how different species differ and which creature created the structure first. Anatomical characteristics observed in several species that have a common ancestor include what are known as homologous structures.
Although these structures may have diverse purposes in many creatures, their similarities suggest that they had an ancestor.
The anatomical characteristics of several creatures may be compared to find homologous structures and deduce evolutionary links.
Because diverse kinds of creatures have homologous features, it is likely that these qualities were passed down from a common ancestor.
Similarity levels and common anatomical patterns might shed light on a species' evolutionary path.

Answer:
How are animals similar? All animals are made of many cells. Most animals can move on their own. Like all living things, animals grow, change, reproduce, and respond to their environment.
Animals are made up of several cells. Most animals have independent movement. Animals develop, transform, reproduce, and react to their surroundings like all other living creatures do.
What are considered as animals?Any eukaryotic multicellular organism of the biological kingdom Animalia is referred to as an animal.
The majority of creatures in this kingdom lack a cell wall, are heterotrophic, motile, have specialised sensory organs, and originate from blastulae during embryonic development.
According to some, the fundamental distinctions between humans and other animal species are our capacity for complex reasoning, our use of complex language.
Also, the capacity for problem-solving, and the capacity for introspection (this means describing your own thoughts and feelings).

Based on the diagram, what would happen if Earth had no atmosphere?
Diagram of greenhouse effect showing the sun, atmosphere, and human activities that release greenhouse gases. The diagram shows that sunlight is reflected back to space by the atmosphere, absorbed at the surface, and reflected by the surface. Greenhouse gases trap heat from the sun. Examples of human activities include CFCs and haloalkane from refrigerators and aerosols, nitrous oxide from gasoline and agriculture, methane from cattle and fertilizer, and carbon dioxide from oil and coal.
Human activities would not release greenhouse gases.
Greenhouse gases would not trap heat from the sun.
Sunlight would not be absorbed at the surface.
Surface temperatures would be maintained.
Based on the diagram, we can confirm that if Earth had no atmosphere, Greenhouse gases would not trap heat from the sun.
Why would these gases not trap heat from the sun without the atmosphere?Greenhouse gases are located in the atmosphere, therefore, without it, they would not be able to trap the heat from the sun. Although high concentrations of these gases are a modern problem in global warming, these gases are a natural part of the earth and are necessary to maintain livable temperatures at the surface of the earth.
Therefore, we can confirm that if Earth had no atmosphere, Greenhouse gases would not trap heat from the sun.

Which mrna sequences would form a structure that is a cue for transcription termination of some genes?
Answer:
First, you must know what the stop codons are: UAA, UAG, and UGA
Whenever this sequence is read, it signals for an end in transcription and amino acids will stop being formed
Thus, 5′−GGCCCUUUUAGGGCCUUUUU−3′ contains a cue for transcription termination as it will stop after the codon "UAG"
Explanation:
Those mRNA sequences that consist of the stop codons like UAA, UGA, and UAG would form a structure that is a cue for transcription termination of some genes.
What do you mean by Transcription?Transcription may be defined as the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA).
Stop codons are responsible for the termination of transcription of almost all the genes. They are necessary for inhibiting the excessive expression of some genes.

Which of the following best explains why deforestation increases the risk of floods in an area? a. Tree leaves catch and retain rain water. B. Trees block the free flow of water. C. Deforestation increases precipitation. D. Tree roots improve soil water retention. Please select the best answer from the choices provided A B C D.
Deforestation increases the risk of floods in an area tree roots improve soil water retention.
Why does deforestation result in higher flood risk?When deforestation takes place, the top layer of soil can be dislodged – this is also known as soil erosion.
When the top layer of soil is unstable, it is unable to retain any of the water that falls on it, resulting in increased surface run-off, which, in turn, increases the risk of flooding.
