Ways in which tadpoles and frogs different from each other

Answers

Tadpoles don't havel egs, just small tales. They are basically a very small undeveloped frog, like a human foetus is completely undeveloped. It has to also stay in water. Frogs on the other hand have legs and are differently colored and can reproduce. They are adult, fully developed versions of tadpoles.

What is the term for a reaction in which a substance gains electrons?a.)respiration
b.)redox reaction
c.)reduction
d.)oxidation

Answers

Answer:

The correct answer would be c.)reduction

Oxidation and reduction occur when transfer of electrons takes place from one element or atom to another.

The atom which receives or gains electron is said to be reduced while the atom which looses an electron is said to be oxidized.

For example, in cellular respiration oxygen gains electrons and H⁺ ions and is converted into water which is released as the byproduct of the process.

1/2 O₂ + 2 e⁻ + 2 H⁺ → 2H₂O

reduction

"Reduction refers to ( chemical reactions in which a molecule gains electrons.)"

The cells of plants and animals are similar, except for a few different structures. Which structures are only found in plant cells?

Answers

The cells of plantsand animals are similar expect for a few different structures like the shape ofthe cells and cell wall. They differ in cell shape since animal cells are roundedand it has irregular shape while plant cells have fixed shape which isrectangular. Another structure is a cell wall. Animal cells don’t have cell wallwhile plant cells have. Plant cell wall is a structure surrounding the cellthat provides a number of functions such as strength to support the plant, Flexibility,Water-proofing, Barrier to pests, Protection against environmental stress, signalingand sensing.

Structures that only plant cells have is a cell wall.

Answers

Argon is a chemical element which is a gas at room temperature, has 8 valence electrons and 22 neutrons. This element belongs to the noble gas elements group.

What is Argon?

Noble gas is any of the rare gases that include helium, neon, argon, krypton, xenon, and sometimes radon also and that exhibit great stability and extremely low reaction rates than other elements in the periodic table.

Argon is a chemical element with the symbol Ar and it has an atomic number of 18. It is in the group 18 of the periodic table and it is a noble gas. Argon is the third-most abundant gas in the Earth's atmosphere, at 0.9340 ppmv. It is more than twice as abundant as that of water vapor, 23 times as abundant as carbon dioxide, and more than 500 times as abundant as neon gas. Argon is the most abundant noble gas in the Earth's crust, which comprises about 0.00015% of the crust.

Argon

Explanation:

1. How does the number of vascular bundles in the root compare to the number of vascular bundles in the stem? 4. In which region of the root would you expect to find the specialized cells of vascular tissue? 5. In which region of the root are the cells genetically identical? Explain why.

Answers

In terms of vascular plants, they help maintain the water cycle. The property of these plants enables them to carry out this function is their well-developed vascular system. These type of plants are more evolved and developed than nonvascular plants because of its specialized characteristics like xylem, which is a tissue that is responsible for its framework and not only that, it is also has a greater mechanism for water transference.

Other Questions

The development of some organisms, like sea turtles, are affected by the temperature at which the eggs are incubated. Typically, cooler temperatures produce more males, and warmer temperatures produce more females. How might climate change affect the reproductive success of sea turtles?Reproductive success will increase, because there will be more nesting ground available due to sea level rises. Reproductive success will increase, because there will be more females to lay eggs. Reproductive success will decrease, because there will be skewed numbers of males and females. Reproductive success will decrease, because there will be longer migration routes due to sea level rises.
