Answer: The correct answer for the blank is-
Pulmonary artery.
Right ventricles receive deoxygented blood ( from right atrium) when tricuspid valves ( present between right atrium and right ventricle) open.
When ventricles contract, this blood flows from right ventricles to pulmonary artery, which takes it to the lungs.
In other words, the deoxygenated blood ( carbon dioxide containing blood) is sent to lungs via pulmonary artery so that it is exchanged with the oxygenated blood at lungs, which is then sent to the heart for its circulation in the entire body.
Answer:
x=7
Explanation:
11=2x-3
Simplify it
14=2x
Divide each side by 2
x=7
Answer:I'm not sure the answer but I'm pretty sure if you divide 11 by 2x-3 you'll get the answer which a calculator can provide :)
Explanation:I think this is how you do it been a while since I had to do that kind of stuff
b. climate
c. primary consumers
d. producers
Answer:
Cytochrome C; it provides evidences that there is similarities in the respiratory pathways for producing ATPs by all living organisms especially mammals.
Explanation:
Cytochrome c is located in the intermembranes of mitochondria, and it functions in the transfer of of one electron in electron transport chain,(ETC) needed for generation of proton motive force; for generation of energy in the synthesis of ATPs by ATPase synthase during chemiosmosis. Its allows oxdation-reduction by the switching of its iron ii to iron iii. during electron transports.However its iron atoms does not undergo oxidation with oxygen. This feature makes it stable and an ideal carrier of electrons.
Its amino acid sequences is very similar in all living organisms especially between mammals(e.g man and chimpanzees)with little variation in few amino acid residues due to mutation.This similarity in its amino acids sequences in all living organism together with small molecular size makes it ideal molecular evidence for studying comparative molecular evidence of evolution.
This is because it can be used to trace the pathways of respiration to synthesize energy, and therefore to conclude that most organisms share common ancestry, since a very similar protein sequence in a structure(Cytochrome c) participated in unique ETC mechanisms in all, needed for energy synthesis .
B.)temporal
C.)geographical
D.)anatomical
A reproductive isolation mechanism in which females prefer to mate with males of their own species is a BEHAVIORAL mechanism.
These barriers to fertilization can be divided into:
In conclusion, a reproductive isolation mechanism in which females prefer to mate with males of their own species is a BEHAVIORAL mechanism.

The isolating mechanism involved is the behavioral change (A).
Further Explanation:
Isolating mechanism are those characteristics of the species that prevents them to reproduce with other members of the species.
There are various types of isolating mechanism:
1. Behavioral- Reproductive isolation that arises due to the behavior of the individual during their mating period.
2. Temporal- The species breeds at different time or they may have different breeding season, therefore this can lead to reproductive isolation.
3. Geographical- The isolation of species because they occupies different habitats.
4. Anatomical- Isolation that arises due to different internal structure of the species.
Example of isolating mechanism - when two species of flies, Drosophila melanogaster and Drosophila simulans, can mate however they usually do not mate. But even though they are kept with each other in any lab, males court the females of both species but the females prefers to mate with males that belongs to the same species.This example shows the behavioral isolation.

B. A single-stranded RNA molecule forms.
C. The DNA transfers its information to RNA through an amino acid.
D. The DNA molecule unzips along weak hydrogen bonds.
DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. The option (D) is correct.
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.
Moreover, DNA must replicate (copy) itself so that each resulting cell after mitosis and cell division has the same DNA as the parent cell. All these cells, the parent cell and the two new daughter cells, are genetically identical.
Therefore, DNA replication is the process of creating two identical daughter strands of DNA. DNA replication occurs in the nucleus in eukaryotic cells and in the nucleoid region in prokaryotic cells. DNA replication occurs in S phase during the cell cycle prior to cell division.

Answer:
D
Explanation:
The first step in DNA replication is to 'unzip' the double helix structure of the DNA molecule. This is carried out by an enzyme, called helicase which breaks the hydrogen bonds? holding the complementary bases of DNA together
