Answer:
The heart consists of four chambers organized into two pumps (right and left) for the purpose of providing blood flow to the systemic and pulmonary circulations. The right atrium receives deoxygenated blood from the entire body except for the lungs via the superior and inferior vena cavae!
The heart has four chambers: two atria and two ventricles.
The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle.
The right ventricle pumps the oxygen-poor blood to the lungs.
The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle.
The left ventricle pumps the oxygen-rich blood to the body.
Hope this helps!

Why is photosynthesis so important to living organisms?
Most consumers can convert energy into food, but they can’t make enough of it, so they need producers, too.
Consumers do not usually live in areas where they can get energy, so they have to eat producers to get enough energy.
All living organisms need energy to stay alive, but only producers can directly convert energy into food.
Decomposers take so long to recycle dead and decaying matter that producers have to make up the difference.
Answer:
All living organisms need energy to stay alive, but only producers can directly convert energy into food.
Explanation:
The process of photosynthesis is very important because all living organisms need energy to stay alive, but only producers can directly convert energy into food.
Photosynthesis is the process whereby green plants manufacture their food in the presence of carbon dioxide and water.
They take light energy from the sun and produce food materials. The light energy is converted to chemical energy which are stored in carbon chains as glucose. The chemical energy is then used by other living organisms for their own nourishment.Why is the decomposing web important

If a red fur male is crossed with a brown fur female, what percent of the offspring would have the genotype
Answer:
If the brown male had been BB, then all offspring would have been Bb and all brown. However, if the male is Bb as above and you perform a testcross, 50% of all offspring should have the bb genotype and a white phenotype. A testcross to a heterozygous individual should always yield about a 1:1 ratio of the dominant to recessive phenotype. So, both the genotypic and phenotypic ratios

- What is the role of mRNA in expressing specialized structures?
F Making energy available for cellular activities
G Creating bonds to form biomolecules
H Producing sugars that assist with replication
J
Providing information to form proteins
Answer:J providing information to form proteins
Explanation:
The role of mRNA in expressing specialized structures is providing information to form protein. The correct option is J.
What is mRNA?Messenger ribonucleic acid is a single-stranded RNA molecule that equates to a gene's nucleotide makeup and is read by a ribosome during the protein polymerization reaction.
The function of mRNA is to transport protein details from the nucleus of a cell to the cytoplasm.
Here the protein-making equipment likes to read the mRNA sequence as well as translates each three-base codon into the corresponding amino acid in a burgeoning protein chain.
Messenger RNAs are single-stranded molecules that move genetic information from the nucleus to the cytoplasm, in which proteins are sequenced.
Thus, the correct option is J.

DNA replication results in two identical daughter molecules each consisting of one old (original) strand and one newly-synthesized strand.
True
False
Answer:
true
Explanation:
please mark me brainliest
DNA replication results in two identical daughter molecules each consisting of one old (original) strand and one newly-synthesized strand. Therefore, it is true.
What is DNA replication?The process of duplicating the parent DNA helix into two identical daughter helices is known as DNA replication. One parent strand is passed down to each daughter strand in this semi-conservative procedure.
In prokaryotic cells, DNA replication takes place in the nucleoid area, whereas it happens in the nucleus in eukaryotic cells. Prior to cell division, DNA replication takes place in the S phase of the cell cycle.
Replication fork pairs that form at the origins of replication and then move in opposition to one another carryout genome duplication. When convergent replication forks meet, DNA replication is complete. Hence, it is true.

How do guard cells maintain homeostasis?
Answer:
Explanation: Guard cells in the plants prevent water loss from it in cases of soil dryness or high temperature by closing themselves. If this does not happen, water will keep leaving the plant by the process of transpiration in these harsh conditions and the plant will not have the important medium for the homeostasis process to continue.

as the lumbar and sacral nerves extend inferiorly beyond the end of the spinal cord, they form the .
The lumbar and sacral nerves extend inferiorly beyond the end of the spinal cord, they form the Cauda Equina.
What is Cauda Equina?
The cauda equina, a group of nerves near the end of the spinal cord, is so named because it resembles a horse's tail. The top part of the lumbar (lower back) spine is where the spinal cord terminates.
The separate nerve roots that provide the legs and bladder with motor and sensory function continue along the spinal canal at the spinal cord's extremity. These nerve roots continue in the lumbar and sacral region as the cauda equina. These nerves carry signals to and from the pelvic organs and lower limbs.
Cauda equina syndrome (CES) occurs when there is dysfunction of multiple lumbar and sacral nerve roots of the cauda equina.
