A. fewer microorganisms
C. more fish
B. more oxygen
D. more nitrogen compounds
Answer:
more nitrogen compounds
Explanation:
when water is polluted by sewage many microorganisms is present so we can deduct the 1st ans.
as water is polluted the environment is not suitable so living organisms so unpolluted water has more fish than polluted.
there cant be more oxygen in a place where it s polluted coz plants which grow under water wont grow as it is polluted
more nitrogen compounds is the answer because nitrogen compounds are made due to the reactions in polluted water.

A. Their cytoplasm contains organelles.
B. They do not have a rigid outermost layer.
C. The process of obtaining energy requires sugar.
D. They have organelles that are surrounded by membranes.
Only animal cells have the process of obtaining energy through sugar. Plants on the other hand undergo photosynthesis, which uses sunlight instead of sugar.
Hope this helps! Please correct me if I'm wrong :)
Answer:
B. They do not have a rigid outermost layer.
Explanation:
Several organisms, including bacteria and eukaryotes are heterotrophs- this means that they obtain energy through breaking down organic molecules like sugar, and amino acids made by producers.
Animal cells are eukaryotic; all eukayoted may be single-celled, or multicellular, and contain a nucleus containing genetic material along with membrane-bound organelles in their cytoplasms. Animal cells do not contain rigid cell walls, unlike other eukaryotic cell types like plant cells.

Nose color is an inherited trait in dogs. Two puppies from the same set of parents have different color noses. One puppy has a pink nose and one puppy has a black nose. How can puppies from the same set of parents have different color noses?
A.
The pink-nosed puppy and the black nosed puppy must not actually be related.
B.
The pink-nosed puppy and the black nosed puppy inherited different combinations of the genes for nose color from their parents.
C.
The pink-nosed puppy has a different number of chromosomes than the black nosed puppy.
D.
The pink nosed puppy and the black nosed puppy have different chromosomes for the two nose colors.
Answer: B
Explanation:
The pink-nosed puppy and the black nosed puppy inherited different combinations of the genes for nose color from their parents. So, the correct option is (B).
What are Genes?
A gene is the basic physical and functional unit of heredity which are made up of DNA. Every person receives two copies of each gene which is inherited from each parent.
Most genes are the same in all people but there are small number of genes which are slightly different between people. Genes are made of DNA, so each chromosome contains many genes. Genes carry the information that determines traits and characteristics or features that are passed on to other organisms or inherited from parents.
Each cell in the human body contains about 25,000 to 35,000 genes.
Thus, the pink-nosed puppy and the black nosed puppy inherited different combinations of the genes for nose color from their parents. So, the correct option is (B).

Distinguish between:
Bat and Dove
Answer and Explanation:
Bats are mammals of the order Chiroptera. With their forelimbs adapted as wings, they are the only mammals capable of true and sustained flight. Bats are more manoeuvrable than birds, flying with their very long spread-out digits covered with a thin membrane or patagium.
Their wings skeleton have the shape of finger/hands like a human.
Doves are the only family in the order Columbiformes. These are stout-bodied birds with short necks, and short slender bills that in some species feature fleshy ceres. They primarily feed on seeds, fruits, and plants.
#teamtrees #WAP (Water And Plant)
Answer:
Doves have beaks and no teeth, whereas bats have jaw bones with sharp teeth. Although they both fly, Dove and bats feature different structures that allow them to take flight. Doves have rigid, feathered wings that they flap completely in order to fly.
Cell division is completed when which step is finished? (SE 5A) Select one: a. interphase b. telophase c. mitosis d. cytokinesis
Answer: Cytokinesis
Explanation: I am taking this same test right now and got it correct.
Cell division is completed when cytokinesis, which is the final step of mitosis, referring to cytoplasmic division, is completed. So the correct option is D.
What is mitosis?A kind of cell division known as mitosis occurs when a single cell (the mother) splits into two genetically identical daughter cells. Mitosis, when referring to the cell cycle, is the stage of cell division during which the DNA in the cell's nucleus is divided into two identical sets of chromosomes.
Mitosis is used in the vast majority of cell divisions that take place in your body. Mitosis fills an organism's body with cells during development and growth, and it substitutes old, tattered new cells over the course of an organism's existence. Mitotic divisions are a kind of reproduction for single-celled eukaryotes like yeast, resulting in the generation of new members of the population.
In each of these scenarios, ensuring that each daughter cell receives a flawless, complete set of chromosomes is the "objective" of mitosis. In general, cells with too few or too many chromosomes don't function effectively; they may die off or potentially spread cancer. Thus, during mitosis, cells don't just randomly split their DNA into two heaps for the two daughter cells. Instead, they divided up their duplicate chromosomes in a methodical order.
Therefore the correct option is D.

Which title best reflects the main idea of the passage?
The Sun transfers energy in the form of heat to Earth through radiation. The ground gets warmer as heat flows from one ground particle (such as soil particles or rocks) to another. The ground heats up the air above it through conduction when the particles of air absorb heat from the particles of the ground. Heat also flows from the ground to the air through radiation. The warmed mass of air becomes less dense and rises. As it rises, it loses heat to the environment, so it cools and becomes more dense. The cool, dense air sinks and takes the place of the warm, less dense air. This convection process transfers heat from Earth’s surface to the atmosphere and moves heat around Earth.

Answer:
DNA is copied and transcribed into another form. This smaller segment is made of genes.
Explanation:
Cell growth, replication, and cell repair are controlled by genetic material found within DNA molecules. These deoxyribonucleic acids' long-chain helical macromolecules are assembled from complex sequences called nucleotides; strong covalent bonds attach these four monomers (adenine, cytosine, guanine, thymine).
Coding regions of DNA are called genes- they contain specific instructions for the cell. Genes can include multiple nucleotides and even several chromosomes. Gene expression typically includes transcription into RNA, and translation into amino acids/ proteins.
