Brendan made a chart to categorize the characteristics of animals.
An empty 2-column table titled Characteristics of Animals. Column 1 is labeled Always. Column 2 is labeled Sometimes.
Which phrase should be written in the column titled "Sometimes”?
Are multicellular
Have membrane-bound organelles
Produce their own food
Display an asymmetrical body plan
Answer:
Im gonna say produce their own food, i may or may not be wrong. sorry
Explanation:
Animals are multicellular and have membrane-bound organelles, sometimes display an asymmetrical body plan and sometimes they produce their own food. Thus, the correct option are C and D.
What is an asymmetrical body plan?Animals are the organisms which are multicellular eukaryotic organisms. Animals have all membrane-bound organelles such as mitochondria, chloroplast, etc.
Animals sometimes produce their own food. Animals also are asymmetrical sometimes because they have disproportionate arrangement of body parts, which exhibits no pattern. However, animals are also symmetrical sometimes because of the proportional arrangement of body parts and pattern.
Therefore, the correct option are C and D.

>> what specific function does the term, respiration, refer to in animals?
Answer:
respiration is a process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances.
What can you infer about the available matter and energy at each level?
Answer:
Matter and energy are distributed differently in different ecosystems. For example, a single tree in a rain forest would be greatly outnumbered by the primary and secondary consumers, such as the insects and birds, that live on that tree. The upper layers of the pyramid of numbers would be larger than the bottom layer representing the single tree.
where are peripheral proteins located
Answer:
Explanation:
Peripheral membrane proteins are found on the outside and inside surfaces of membranes, attached either to integral proteins or to phospholipids. Unlike integral membrane proteins, peripheral membrane proteins do not stick into the hydrophobic core of the membrane, and they tend to be more loosely attached.
Which quality makes Earth particularly well-suited to support life?
O A. Its axis precesses about every 26,000 years.
O B. It is roughly the same age as the sun.
O C. It features a wide variety of topographies.
OD. Its distance from the sun helps maintain a narrow temperature
range.
What does it mean that there is both unity and diversity of life at the level of the cell?
Answer:
All livings organisms are with unicellular origin. The cells have a common structure like cell membrane, DNA , RNA and necessary enzymes. The genetic code of protein synthesis is almost similar with few exceptions. This shows unity in design.
Further evolutionary changes took place due to environmental stress. The genome of each species is designed as per need and efficiency. This is diversity.
This is true with all five kingdoms of life that is monera, protista, fungi, plantae and animalia.

PLEASE HELP! - Describe why carbon, hydrogen, oxygen, nitrogen, & other elements can combine. Describe the results of these combinations.
Answer:
2hydogen + 1oxygen = H2O = water
Explanation:
The answer lies with carbon's unique properties. Carbon has an exceptional ability to bind with a wide variety of other elements. Carbon atoms can form multiple stable bonds with other small atoms, including hydrogen, oxygen, and nitrogen. Carbon atoms can also form stable bonds with other carbon atoms.
why is it important for environmental scientists to have a background in many fields of study
Answer:
With these rapid changes, there is a need to study each step that may alter the environment so that the natural ecosystem may still be protected or replaced by a better one. Environmental science is important to save our world from destruction. Because of man's abusive actions, the environment is not safe anymore.
Explain how the structure (order) of DNA can determine the structure of a protein. Use as many of the following terms as you can in your explanation: DNA, base pairs, mRNA, tRNA, ribosome, amino acid, protein, codon, anticodon
The stages of DNA bases in a molecule can determine the order of amino acids in protein molecules. Groups of three bases called triplets represent different amino acids. This is the basis of the genetic code . A sequence of bases (genetic information) on DNA that codes for a protein is called a gene
Protein synthesis is the generation of proteins by cells that employ DNA, RNA, and different enzymes.
What is protein synthesis?It generally includes transcription, translation, and post-translational events, such as protein folding, modifications, and proteolysis the process of protein synthesis.
the mRNA contains the sequence of nucleotides transcribed from the DNA that defines the sequence of amino acids that a synthesized protein will have.
In mRNA, codons are triplets of nitrogenous nucleotides that code for amino acids and using ribosomes mark the beginning and end of protein synthesis.
Therefore, in contrast to mRNA codons, anticodons are triplets of nucleotides found in transfer RNA (tRNA). The linking of amino acids to the polypeptide chain being produced is carried out by tRNA.

why are fossil fuels supplies limited
Answer: The coal, oil and natural gas we are consuming now are the remnants of plants, trees and animals that were living hundreds of millions of years ago. There is no way to replace them, as conditions on Earth are much different now.
Explanation: Mines and wells are being depleted much faster than they were a hundred years ago when demand was much less-- fewer people, fewer cars, fewer planes. . . and people believed there was an endless supply. Many of those mines and oil wells are now empty.

Describe the relationship between a tree and a cow. (Use terms like oxygen, carbon dioxide, photosynthesis, and cellular respiration)
Answer:
Without the tree the cow couldn't live.
Explanation
The cow breathes in oxygen and breathes out carbon dioxide. The tree uses cellular respiration and photosynthesis in order to take carbon dioxide (which the cow produces) and make it into oxygen (which the cow needs to breaths).
11. Many plants use brightly colored flowers to attract insect pollinators.
Which is the MOST likely conclusion about a plant that has very small flowers that
are hard to see?
CLE
Answer: Pollen can be blown in the wind which the bees/other pollinators can follow to get to the flowers.
Explanation: Plants rely on bees and other insects to reproduce and so they have adapted, over time, to become more attractive to them. Bees are drawn to plants with open or flat tubular flowers with lots of pollen and nectar. A flower's scent can have particular appeal to bees, and its bright colors or pollen being blown in the wind may lure the bees in.
