Answer:
It has four chambers.
Explanation:
The structure of human heart has four-chambers consist of two atrium and two ventricles. The right atrium receive blood from the whole body, while the ventricles pump blood to the whole body. The right atrium receives blood from the superior and inferior vena cavas. This blood then moves to the right ventricle where it is pumped to the lungs for purification or to dispose off carbondioxide and loaded the blood with oxygen. The left atrium receives blood from the lungs while the left ventricle pumps this blood to all parts of the body.

At the site of gas exchange in the lungs, oxygen moves from the alveoli to the red blood cells. Details about gaseous exchange can be found below.
What is gaseous exchange?Gaseous exchange is the process whereby gaseous substances especially oxygen and carbon dioxide move from one point to another in living systems.
Oxygen from the atmosphere goes into the body via the nose and is passed on to the lungs. The gases are exchanged in a compartment called alveoli or air sac.
The air sac then passes the oxygen to the red blood cells, which circulate it round the body to organs.

Obsidians glassy texture indicates that it formed
Answer:
on the surface rapidly
Explanation:
Obsidian glassy texture indicates that the rock formed on the surface rapidly.
Like every other magma, the condition of the environment determines how the magma cools and solidifies.
When magma cools rapidly, nucleation centers will be difficult to come- by .. At nucleation centers, minerals aggregates and grows to form different grain sizes. When rapid cooling occurs, not enough time is given for the aggregation around the nucleus. This leaves a rock mass that is finely grained.what is a natural depression filled with standing freshwater called please help

You are involved in a biodiversity survey and encounter a meadow of grass. How would you best describe the grass?
Answer:
Monocot
Explanation:
All flowering plants (Angiosperms) are classified into monocots and dicots. Monocotyledons are plants that have one seed leaf (cotyledon) when the seeds germinate. These plants also have other features such as, for example, parallel-veined leaves, adventitious root system, flower parts in multiples of threes (i.e., 3, 6 or 9 petals), etc. Poaceae (Gramineae), also known as grasses, is a large family of monocotyledonous plants. Therefore, all the grasses are monocot.
Which three organization levels are in a human stomach?
Muti choice
1) cell
2)organ
3)organ system
4)organism
5)tissue
Answer:
Cell Organ System Organ
Explanation:
cells make up everything as a building block of life.
Answer:
Cell, tissue, and organ.
Explanation:
A cell is an obvious one because it makes up the tissue, and it is needed in order to form an organ. Meaning tissue and cell would have to be included. Tissues witch are made of many cells form an organ, and an organ would be the human stomach/digestive system. It can't be organ system because a stomach can't be a whole system including the heart and ect. It can't be organism because a stomach isn't enough organ systems to create an organism.

What is the minimum pH difference such that transfer of one H ion across the membrane would provide enough energy to make one molecule of ATP?
Answer:
The minimum difference is already the value of 1
Explanation:
When the pH is not balanced between the extracellular and intracellular environment, the cell could go into shock, that is why in the face of the minimal differences in pH between the internal or external environment, the proton pump is activated, this is how the hydrogen ion or positively charged protons cross the membrane and indirectly generate ATP molecules.

In DNA replication:
a) each new single helix is composed of 50 percent protein and 50 percent DNA protein.
b) each new triple helix is composed of one old DNA strand and two new DNA strands.
c) each new double helix is composed of one old protein strand and one new protein strand.
d) each new double helix is composed of one old DNA strand and one new DNA strand.
In DNA replication, each new double helix is composed of one old DNA strand and one new DNA strand. So, the correct option is (D).
What is DNA replication?DNA replication is defined as the biological process of making two identical copies of DNA from a single original DNA molecule that occurs in all living organisms, acting as the most essential part for biological inheritance.
It is the process by which the DNA of the genome is copied into cells, where a cell must first copy (or replicate) its entire genome before dividing so that each resulting daughter cell ends up with its own complete genome.
DNA replication involves:
Replication Fork Formation.Before DNA can replicate, the double stranded molecule must be "unzipped" into two single strands.
Primer Binding.The leading strand is the simplest to replicate.
Elongation.TerminationThus, in DNA replication, each new double helix is composed of one old DNA strand and one new DNA strand. So, the correct option is (D).
