What is the smallest family in the phylum Aves?
The smallest family in the phylum Aves is the bird family.
What is Phylum?Phylum may be defined as a prevalent taxonomic classification that classifies above class and below kingdom, identical to the division in botany.
The phylum Aves are generally adapted to fly. Hence, it consists of birds or organisms who have the ability to fly in the environment and are classified into this category with a lot of exceptions like bats which belong to mammals.
Therefore, the smallest family in the phylum Aves is the bird family.

Explanation:
In eukaryotes, gene expression is regulated mostly by _____.
Answer:
Gene expression in eukaryotic cells is regulated by repressors as well as by transcriptional activators. Like their prokaryotic counterparts, eukaryotic repressors bind to specific DNA sequences and inhibit transcription.
Explanation:
In eukaryotes, gene expression is regulated mostly by transcription factors.
What are transcription factors?Transcription factors are proteins that bind to DNA in the promoter region of a gene, and they play a critical role in controlling when and to what extent a gene is expressed.
They can either activate or repress gene expression by promoting or inhibiting the recruitment of RNA polymerase. Transcription factors are themselves regulated by a variety of signals, including hormones, growth factors, and other external cues, as well as by feedback loops and other regulatory mechanisms within the cell.
Ultimately, this complex interplay of factors allows eukaryotic cells to precisely control which genes are expressed, when they are expressed, and to what degree, enabling them to respond to changing internal and external environments.

A. plasma membrane
B. nucleus
C. flagella
D. cell wall
Nucleus is an exception in a prokaryotic cell. Thus, option A, C and D are correct.
What are the characteristics of a prokaryotes?Prokaryotes are microscopic and primitive cells. Their nucleus is not well developed.
Prokaryotes lack cell organelles like mitochondria, endoplasmic reticulum, Golgi body etc in their cell structure.
Prokaryotes are simple in assembly and are therefore unicellular. A single cell performs all the functions in the body.
Prokaryotes have single chromosome present in their structure. Their DNA is found in the cytoplasm.
Prokaryotes have cilia and flagella for locomotion.
Prokaryotic organisms are found extensively everywhere on earth. They have unique ability to survive in the harsh environments.
Prokaryotes are beneficial in many ways:

Describe and discuss the amino acids. Include information on what they are, their structure, and how many there are. Using your best grammar, write 3-5 sentences.
Answer:
molecules that combine to form proteins
Explanation:
amino acids are molecules that combine to form proteins. amino acids and proteins are the building blocks of life. when proteins are digested or broken down amino acids are left
Amino acids are building blocks of proteins. They contain an amino group, carboxyl group, and side chain. There are 20 types, each with unique properties influencing protein structure and function.
Biochemical functions depend on amino acids in proteins. The R-group, amino group, and carboxyl group are on each amino acid. This side chain gives each amino acid chemical properties that impact protein structure and function. Twenty typical amino acids make up proteins.
They vary in size, shape, charge, and hydrophobicity. Peptide bonds generate polypeptide chains that fold into three-dimensional forms, determining a protein's function. The structures include simple helices and complex globular shapes. Complex and diverse, proteins perform various tasks in living things due to the diversity of amino acids and their interactions.

Answer:
(Hope this helps can I pls have brainlist (crown)☺️)
Explanation:
They consume food and they have much higher metabolism. That means that more waste products are produced. Plants can use much of the waste produced and it is in fact raw material. Animals don't normally produce their own chemicals from scratch like plants normally do so they can't just recycle the waste. They need to remove it. About the only waste plants need to get rid of is excess oxygen produced during the day. That is actually three reasons but recycling is related to plants not consuming but making their own chemicals from scratch. In a way it pretty much comes down to one main reason.

seeds from a single sexually reproducing plant are harvested and later planted under identical conditions. what results should be expected?
At this point, 6 carbon dioxide molecules have
been released (2 from the link reaction and 4
from the Krebs cycle). Why does this make
sense?
Glucose has combined with oxygen to make carbon dioxide.
Glucose has 6 carbons and has been completely broken down by this stage.
The 6 carbon dioxides are reactants that will be used to make ATP.
These 6 carbon dioxides are converted to oxygen by respiration.
All of these.
Glucose has combined with oxygen to make carbon dioxide and Glucose has 6 carbons and has been completely broken down by this stage.
Glucose react with oxygen to make carbon dioxide, water and energy in the form of ATP. Glucose has 6 carbon atoms which react with oxygen that is completely broken down into three products such as carbondioxide, water and energy in the form of ATP by the process of cellular respiration so we can conclude that carbondioxide gas is produced by breaking down of glucose molecules from the Krebs cycle that is a stage of respiration.

Explain how kinetic energy affects each object as it changes its state of matter:
A) Water boiling:

C) Water condensing on the side of a water bottle:
Answer:
Explain how kinetic energy affects each object as it changes its state of matter:
A) Water boiling:
B) Popsicle freezing:
C) Water condensing on the side of a water bottle:
Explanation:
A) A water boiling will result in evaporation, therefore the particles will move extensively faster than liquid due to it being vapor.
B) A popsicle freezing is originally a solid so it'll have the least amount of kinetic energy as the particles remain fairly slow.
C) Due to the fact that water is condensing, while turning into a liquid. The water condensing on the side of the water bottle would produce a lower kinetic energy level due to the fact that it's becoming a liquid. Though liquids have higher kinetic energy than solids, as gases have a higher kinetic energy compared to liquids.
Evaporation from boiling water causes the particles to move much more quickly than they would in a liquid state.
What is Kinetic energy?A popsicle is initially a solid, it will have the least kinetic energy because the particles are still moving slowly. Because water is condensing as it transforms into a liquid.
Because it is turning into a liquid, the water that is condensing on the water bottle's side would have less kinetic energy.
Gases have a higher kinetic energy than liquids, despite the fact that liquids have a higher kinetic energy than solids.
Therefore, Evaporation from boiling water causes the particles to move much more quickly than they would in a liquid state.
