A) All life on Earth has DNA that encodes for traits.
B) All life on Earth has a similar codon to amino acid translation.
C) All life on Earth uses ribosomes to assemble polypeptides from mRNA.
What are genetic codes?The four different nucleotide types that make up our genetic code are thymine, adenine, guanine, and cytosine. There are more of them, but for this question, let's focus on these four.
Every living thing on earth contains the same four nucleotides, but how they are arranged during the production of proteins differs. The genetic code will be used to create these proteins.
All organisms are made up of genetic codes. Everybody has different genetic codes.
Therefore, the correct options are a, b, and c.

Which of the following is the best definition of an ecosystem?
O A. A system formed by the interactions of all of the living things
within an area
B. A system formed by the interactions of organisms of the same
species that live in the same area
C. A system formed by the interactions of living organisms with the
nonliving physical environment
D. A system formed by the interactions of all of the nonliving things
that exist in the same area
Answer:
C
Explanation:
ecosystem is living AND non living things
The best definition of an ecosystem is option C: "A system formed by the interactions of living organisms with the nonliving physical environment."
What is an ecosystem?An ecosystem is a community of living organisms, such as plants, animals, and microorganisms, interacting with each other and their nonliving environment, including the atmosphere, soil, and water.
This interaction creates a functional system that can be characterized by energy flow and nutrient cycling. The other options are not accurate definitions of an ecosystem, as ecosystems involve both living and nonliving components, and the interactions are not limited to a single species.
Ecosystems are not isolated, and they can interact with other ecosystems. For example, rivers and streams can transport nutrients and organisms downstream, connecting different ecosystems such as a forest and a freshwater system. Similarly, the atmosphere can transport pollutants and other materials across vast distances, affecting ecosystems far from their source.
In summary, an ecosystem is a complex, interconnected system where living organisms interact with each other and the non-living components of their environment. Understanding the functions and interactions within ecosystems is critical to developing effective management strategies for conserving biodiversity and maintaining the ecosystem services that humans depend on.

2. Difference between polar and non-polar molecule.
Eyepiece magnification(EM) X Objective magnification (OM)= Overall Magnification:
Answer:
I. Overall magnification (TM) = x40
II. Overall magnification (TM) = x100
III. Overall magnification (TM) = x400
IV. Overall magnification (TM) = x1000
Explanation:
A microscope can be defined as an optical device that is typically used to make an enlarged (magnified) image of a minute (small) object and as such reveals all the little information about the object that cannot be seen by the natural human eye.
Mathematically, the overall (total) magnification of a microscope is given by the formula;
Overall magnification (TM) = Eyepiece magnification(EM) X Objective magnification (OM).
I. When EM = x10 and OM = x4
TM = EM * OM
TM = x10 * x4
TM = x40
II. When EM = x10 and OM = x10
TM = EM * OM
TM = x10 * x10
TM = x100
III. When EM = x10 and OM = x40
TM = EM * OM
TM = x10 * x40
TM = x400
IV. When EM = x10 and OM = x100
TM = EM * OM
TM = x10 * x100
TM = x1000

8. im not sure abt this one, sry :(
9. yeah, true
10. c
Explanation:
Pro phase is the starting stage of the division where the cell division begins. Spindle fibers are broken into half and the type of division that is present in gametes is reduction division that is the meiosis. Synapsis occurs during mitosis.
What is synapsis ?It is defined as the stage in which the pairing of the homologous chromosomes take place.
Chromosomes do not line at the equator as the lining of the chromosomes at the equator occurs on the stage of mitosis where it is possible to see the V,J and L shapes of the paired chromosomes. After this stage the exchange of genetic material takes place.Chromatin do not change into chromosomes in the metaphase.
Mitosis is present only to make the duplicate copies of the cell. The identical daughter cells are made when the division of mitosis is taking place in the cell. Chromosomes are first visible in the prophase. A centromere holds two sister chromatids together.
In meiosis crossing over takes place in anaphase 1.

PLS HELP ME THANKS :) write a short paragraph evaluating the different methods of seed dispersal.
Explanation:
There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals. Some plants are serotinous and only disperse their seeds in response to an environmental stimulus. Because plants cannot walk around and take their seeds to other places, they have developed other methods to disperse (move) their seeds. Dandelion seeds float away in the wind

Which statement correctly describes the significance of meiosis during gamete formation?
Answer:
Explanation:
During sexual reproduction, meiosis generates genetic variation in offspring because the process randomly shuffles genes across chromosomes and then randomly separates half of those chromosomes into each gamete. The two gametes then randomly fuse to form a new organism.

Matter is anything that has mass and takes up space. It includes molecules, atoms, fundamental particles, and any substance that these particles make up. Matter can change form through physical and chemical changes, but through any of these changes matter is conserved.
In other words, matter doesn't change into a different substance in a physical change. ... Changes of state—for example, from solid to liquid or from liquid to gas—are also physical changes. Some of the processes that cause physical changes include cutting, bending, dissolving, freezing, boiling, and melting.
