In the box provided explain why living organisms
contain more hydrogen atoms than any other
atoms, yet 65% of a typical organism's mass is
oxygen
І

Answers

Answer 1

Answer:

Explanation:

Living organisms are mostly made of water. Water is a molecule made from 2 hydrogen atoms and 1 oxygen atom, H2O. Now even though there are 2 hydrogen atoms for every oxygen atom in a living organism oxygen atoms are much heavier than hydrogen atoms. Hydrogen atoms are more than 15 times lighter than oxygen atoms and this is why they can be fewer atoms of oxygen in the body but they will still represent a lot of its weight.

Answer 2

Answer:

The living species comprise more number of hydrogen atoms in comparison to any other atoms, still 65 percent of the usual organism's mass is oxygen. The prime reason for this is that an atom of oxygen comprises sixteen times more mass in comparison to a hydrogen atom.

What does the energy from sunlight actually do to the plant cell? *
It heats up the plant cell
It excites electrons
It is unknown
It transforms to kinetic energy

Answers

Answer:

It excites electrons

Explanation:

Energy from sunlight excites electrons in plant cells and drives the chemical reaction needed to produce food in plants.

This reaction is called photosynthesis. During photosynthesis, green plants manufacture their food using sunlight in the presence of carbon dioxide and water. The product of the reaction is glucose and oxygen gas. The role of the sunlight is to excite electrons which facilitates the process.

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.

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

What is cellular respiration?

Cellular respiration is a sequence of chemical processes that decompose glucose to start producing ATP, which can then be used as energy to power a wide range of processes throughout the body.

Cellular respiration consists of three major steps namely glycolysis, the citric acid cycle, and oxidative phosphorylation.

The use of photoautotrophic procedures to obtain the glucose required for cellular respiration is an illustration of cellular respiration in plants.

This means that plants can use light energy from the sun to produce glucose and oxygen.

On the other hand, the process of photosynthesis utilizes carbon dioxide and release oxygen as a byproduct.

Thus, the correct option is C.

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.
