Which organism would be classified as an echinoderm?
squid
sea star

Answer:
Sea star
Explanation:
The phylum Echinodermata contains organisms that share a specific set of characteristics, including spiny or bumpy skin. There are five different classes of animals in the phylum: starfish (also known as sea star), brittle stars, echinoids (which include the sea urchins and sand dollars), sea cucumbers, and sea lilies.

While all zebras have stripes, no two zebras share the same pattern. Variation, overpopulation or adaptation
Answer:
Variation
Explanation:
"Overpopulation" describes an issue in which there are too many of a certain organism.
"Adaptation" describes a phenomena where an organism evolves to adapt in its environment.
Well, lets compare zebra stripes to fingerprints. Fingerprints have nothing to do with overpopulation, and unique fingerprint patterns have nothing to do with adaptation, but the seemingly infinite variation in both fingerprints and zebra stripes is definitely there. So, the uniqueness of the patterns throughout each zebra individual is variation.
Which of the following describes the relationship between genes and
chromosomes?
Chromosomes form into genes during cellular reproduction
Genes are special sequences of nucleic acids found on chromosomes
Every gene an organism has is found on every one of its chromosomes
All of an organism's chromosomes can be found next to its genes in the cell nucleus
Answer:
Genes are special sequences of nucleic acids found on chromosomes.
Explanation:
A single DNA molecule is a chromosome. A gene is a certain chromosome region of DNA.
All cells of the body are genetically the same, but cells are different from others because specific gene sets are expressed. Different cells, therefore express different genes, which enable them to perform a specific function.
The deoxyribonucleic (DNA) genes are segments that contain a code for a certain protein that works in one or several cell types in the body. Chromosomes are cellular structures that contain the genes of a person. Genes that are in the cellular nucleus are contained in chromosomes.

One species benefits and the other species is neither harmed nor helped.
Both species benefit.
One species benefits and the other species is harmed.
Answer:
Commensalism - one specie benefits and the other species is neither harmed nor helped .
Symbiosis - both species benefit
parasitism - one species benefit and the other species is harmed

An advantage of asexual reproduction is that it __________. Group of answer choices allows a species to easily rid itself of harmful mutations enhances genetic variability in the species allows the species to endure long periods of unstable environmental conditions produces offspring that respond effectively to new pathogens maintains successful genetic combinations without modification
Answer:
Maintains successful genetic combinations without modification.
Explanation:
Asexual reproduction usually creates perfect copies of the parent. If the parent is genetically sound creature, then a successful genetic combination is being reproduced and maintained without any changes or modification.

What are the two main components of the cell cycle
In eukaryotic cells or cells with a nucleus, the stages of the cell cycle are divided into two major phases: interphase and the mitotic (M) phase.
What is cell cycle?
The cell cycle, or cell-division cycle, is the series of events that take place in a cell that cause it to divide into two daughter cells. These events include the duplication of its DNA (DNA replication) and some of its organelles, and subsequently the partitioning of its cytoplasm and other components into two daughter cells in a process called cell division.
In cells with nuclei (eukaryotes, i.e., animal, plant, fungal, and protist cells), the cell cycle is divided into two main stages: interphase and the mitotic (M) phase (including mitosis and cytokinesis). During interphase, the cell grows, accumulating nutrients needed for mitosis, and replicates its DNA and some of its organelles. During the mitotic phase, the replicated chromosomes, organelles, and cytoplasm separate into two new daughter cells. To ensure the proper replication of cellular components and division, there are control mechanisms known as cell cycle checkpoints after each of the key steps of the cycle that determine if the cell can progress to the next phase.
In cells without nuclei (prokaryotes, i.e., bacteria and archaea), the cell cycle is divided into the B, C, and D periods. The B period extends from the end of cell division to the beginning of DNA replication. DNA replication occurs during the C period. The D period refers to the stage between the end of DNA replication and the splitting of the bacterial cell into two daughter cells.

A solar eclipse happens when --
the sun is directly between Earth and moon
the moon is in Earth's shadow.
the moon is directly between Earth and sun.
the sun blocks out light from Earth.
When the Moon passes between Sun and Earth, the lunar shadow is seen as a solar eclipse on Earth. When Earth passes directly between Sun and Moon, its shadow creates a lunar eclipse. Lunar eclipses can happen only when the Moon is opposite the Sun in the sky, a monthly occurrence we know as a full Moon.

based on Mr. Kaku's assertion that knowing what the stars are made of is as easy as running starlight through a prism, use the CER method to explain the use of light to determine composition of a star in detail.
Answer:
spectroscopy.
Explanation:
The use of light to determine composition of a star is known as spectroscopy. When astronomers look at an object's spectrum, they can find out its composition based on the wavelengths of light. Spectroscopy is the most common method astronomers use for knowing the composition of stars, planets, and other objects so we can conclude that spectroscopy is the method which is used to determine the composition of stars.

A)The rib muscles contract and move upward
B)The chest cavity expands and grows larger
C)The diaphragm relaxes and moves upward
D)The lungs contract and expand
Answer:
The answer is C.
