How are the bodies of the three animals similar to one another? How are they different?
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).
Multiple cells make up an animal. The majority of animals can move on their own. Like all other living things, animals grow, change, reproduce, and respond to their surroundings.
Thus, this way, many animals contrasts each other.

How is gravity simulated on the hermes spacecraft?.
Answer:
A section of the spacecraft is slowly rotated in order to simulate the force of gravity.

The rotational force of the spacecraft makes an artificial sort of gravity, which can be altered by changing the speed of the spinning or by moving the rotating part further/closer to the center point of rotation.
If you find a rock that has a belemnite fossil in it. how old is the rock? Explain your reasoning
Answer:
See below.
Explanation:
Belemnites is a genus of an extinct group of cephalopodsThese cephalopods existed in the Early Jurassic period from the Hettangian age (196.5–199.6 million years ago) to the Toarcian age (175.6–183.0 million years ago). Therefore, the discovered rock could be anywhere from 175.6 - 196.5 million years oldIn 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.
What system plays a vital role in the existence of the human species?
What's the ans?
Answer:
The reproductive system.

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.

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.
Thus, option "D" is correct.

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.
