The duck-billed platypus’s name come from its snout, which looks a lot like a duck’s bill. It has another birdlike characteristic; it lays eggs, which is quite unusual for mammals. In fact, there are only five known mammals that lay eggs. The other four are four species of echidna, also called the spiny anteater. The duck-billed platypus is classified as a mammal because it has body hair, it’s warm-blooded, and the females produce milk.

Answer:
In solids, particles have greater amount of attractive forces, they have fixed shapes and less energy.
In liquids, particles have weak forces of attraction b\w them, they take the shape of their container and have more energy. The often slide pass each other.
In gases, particles have almost no amount of attractive forces, they have no fixed shape and much more energy. They can move freely .

Explain Why is there a net gain of onlý two ATP
molecules in the glycolysis of one six-carbon glucose?
Answers
Answer:
While 4 molecules of ATP are produced in total, 2 were used to convert glucose to the reactive fructose-1,6-bisphosphate
Thus, 4 ATP- 2ATP= 2ATP
Explanation:
In the cytoplasm, cellular respiration starts, where glucose is broken down for energy production. in the presence of oxygen, energy is produced through aerobic respiration, while in an oxygen-deprived environment, anaerobic respiration can be carried out.
Glucose is a relatively stable molecule, thus in order for the pyruvate-producing reaction to occur, the molecule undergoes phosphorylation through the addition of high energy phosphate groups to drive the reaction forward.
Pyruvate is generated through glycolysis in the cytoplasm-it is oxidized to form acetyl CoA in aeroboc respration also used in fermentation (anaerobic respiration) as an electron acceptor.
There are more hydrogen atoms in living organisms than any other atom, but oxygen is more abundant in terms of

Why is this statement true?
O Hydrogen is a gas, but oxygen is a solid.
O Hydrogen atoms have a lower mass than oxygen atoms.
• Hydrogen atoms make up more of water's mass than oxygen atoms.
Hydrogen is present as single atoms and oxygen is bonded in compounds,
Answers
Answer:
Hydrogen atoms have a lower mass than oxygen atoms.
Explanation:
The statement which is true is Hydrogen atoms have a lower mass than oxygen atoms. Thus, option C is correct.
What is hydrogen?
Hydrogen is the most abundanet element representing nearly three quarters of the mass of the universe. Hydrogen is found in the water that covers 70% of the surface of our planet as well as in all organic matter. Hydrogen is the simplest element in the universe. It is composed only of one proton (p) and only one electron (e-).
Hydrogen is the lightest element of all elements and gases; it is 14 times lighter than air. A "spill" of hydrogen gas immediately diffuses into the air and pollutes neither the ground nor the water table. Hydrogen is invisible, odorless and nontoxic. It does not cause acid rain, does not deplete the ozone layer and does not generate dangerous emissions.
Carbon is so abundant in living things even though oxygen is the most abundant element on Earth because carbon atoms can bond with one another to make chains and cyclic structures whereas oxygen atoms cannot form chains or cyclic structures.
Therefore, The statement which is true is Hydrogen atoms have a lower mass than oxygen atoms. Thus, option C is correct.

Sperm cells of a specific species of mice have 16 chromosomes. What is the expected number of chromosomes in an adult mouse of this species?
Answers
Answer:
32 chromosomes (16 pair)
Explanation:
Gametes or sex cells of sexually reproducing organisms are produced via a process called MEIOSIS, which is a type of cell division that reduces the chromosomal number of the parent cell by half. Hence, a mice that produces a sperm cell (gametes) via meiosis with 16 chromosomes will have double that amount in somatic cells of that mouse.
That is, the expected number of chromosomes in an adult mouse of this species with 16 chromosome in its sperm cell is 32 since half of this number makes up the chromosomal number in gametes
Which genus of single-celled organisms feeds by surrounding its food
with cytoplasm and engulfing it?
Answers
Answer:Amobea
Explanation:
The single-celled organism that feeds its food from the surrounding by engulfing is Amoeba. Amoeba is unicellular organism, generally found in freshwater pools, lakes, and in aquatic vegetation.
Amoeba is a unicellular organism belonging to the group of protozoa. It reproduces through binary fission. The amoeba has the ability to change its shape, which helps the organism to obtain food from the surrounding. Amoeba protrudes the cytoplasm by making a finger-like projections, known as pseudopodia. The pseudopodia engulfs the surrounding food particle by making a food vacuole. This process of engulfing food is known as phagocytosis.
Therefore, the amoeba uses phagocytosis to engulf food particle.

Because most nerve cells do not typically undergo mitosis, they are generally not capable of which of the following?a.producing enzymesb.generating more nerve cellsc.performing cellular respirationd.transporting ions against a concentration gradien
Answers
Answer:
B. generating more nerve cells
Explanation:
Mitosis is the process whereby a cell divides into two genetically identical daughter cells. It is way through which living cells reproduce and multiply themselves.
Hence, a nerve cell that do not typically undergo mitosis will be incapable of replicating/multiplying itself, hence, unable to generate more nerve cells.
