Answer:
The circulatory system or vascular system is an organ system that helps in the transport of the blood from and to the heart. The blood transport also takes oxygen, nutrients, hormones, and other components from the heart to the various part of the brain with the help of the arteries and carry waste such as carbon dioxide to the heart in veins.
The oxygenated blood enters in the left atrium and moves to the left ventricle to the aorta and starts its journey to the body whereas deoxygenated blood enters in the right upper chamber or right atrium of the heart and pump to the right lower chamber and to the lungs to carry the oxygen again. This process is a continuous process.
How is the life cycle of Ascomycetes different from that of humans?
A.
Haploid cells undergo meiosis.
B.
Haploid cells undergo mitosis.
C.
Diploid cells undergo meiosis.
D.
Diploid cells undergo mitosis.
Ascomycetes have a different life cycle from humans in that they go through mitosis in haploid cells.
How do haploid cells work?A cell with a single collection of chromosomes is called haploid. The complement of chromosomes found in sperm or egg cells, often known as gametes, is also referred to as haploid. In humans, sperm and eggs are haploid cells with 23 chromosomes—one of each chromosomal pair found in diplod cells—and are hence haploid.
What are the benefits of haploid cells?Haploid cells are ideal for studying gene function because they only have one copy of something like the genome, making it impossible for changes to be hidden from view. Humans make haploid cells during meiosis.

A limiting factor is an environmental factor that increases the growth of population? True or False
Answer:
False
Explanation:
A limiting factor is the environmental factor that is of predominant importance in restricting the size of a population.
A limiting factor is an environmental factor that increases the growth of population-This statement is false.
Limiting factor:
In biology, the term restricting component is characterized as a natural element or variable that has the ability to limit the development, overflow, or appropriation of a populace in an environment. These elements are available in restricted supply. Subsequently, creatures will generally vie for their restricted accessibility in the environment.
Thus, Limiting factor does not increase the growth of the population.

Answer:
C. Telomere length does not shorten as they age.
Explanation:
A is wrong because Telomerase is expressed in their cells.
B is wrong because chromosomes do replicate as they grow.

When will an insect that undergoes incomplete metamorphosis develop a set of wings?
a.
after its final molt
b.
when it becomes a pupa
c.
when it breaks out of its chrysalis
d.
only insects that undergo complete metamorphosis have wings
Answer:
The answer is D not sure
Explanation:
Like those of several other insect species, the stages of growth that the nymph cricket undergoes are referred to as "instars." Crickets usually go through eight to 10 instars before reaching adulthood, which takes about two to three months. Crickets start to develop wings at about 1 month of age.
How many membranes are does the nucleus have?

what is chromosomes
Answer:
Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.

If you were to find a clean well-sorted sandstone what geologic events may have caused this? How are these events different from those that form an arkose?
Answer: Arenite
Explanation:
Arenite can be defined as the sedimentary clastic rock.
It is of the sand grain size.
It also comprises of matrix.
It is a metamorphosed sediment.
Arenite is formed by the erosion of the turbiditic re-deposition of the sands. It belongs to silicatic limestones.
Do turkeys get sleepy from that thing in turkey that makes you sleepy?
Answer:
Turkey allegedly causes drowsiness because it is packed with a nutrient called tryptophan. Tryptophan is one of 20 naturally occurring amino acids—the building blocks of proteins. Because the body is unable to manufacture tryptophan on its own, it must be obtained from food protein.

Answer:
Estuaries is a water body where freshwater from rivers and streams combines with salt water that is coming from the ocean.
Explanation:
Estuaries is a type of water body that is partially enclosed present at the coastal side where freshwater from rivers and streams combines with salt water that is coming from the ocean. Shallow estuary waters create unique habitats for organisms living there because the presence of brackish water refers to the mixture of fresh water draining from the land and salty seawater. The salinity in water change as you move from inland areas out towards the ocean because the water of inland has less salt in it while water of ocean has huge amount of salt present in it so when we move from inland to the ocean salt concentration increases in it. estuaries provide protection for inland areas by filtering pollutants, prevent shoreline erosion, flooding and storm.
Theoretically, how might researchers disrupt signal transduction pathways as possible treatments for cancer?
a. stimulate production of cAMP in cancer cells.
b. inactivate epinephrine receptors on cancer cells.
c. alter G protein-coupled receptors involved in cell cycle regulation to be active in the absence of their normal signaling molecules.
d. disrupt the function of protein kinases involved in cell cycle regulation.
Answer:
d. disrupt the function of protein kinases involved in cell cycle regulation.
Explanation:
Protein kinases which are useful in cell cycles have major roles in the formation of tumors. So many of these protein kinases go through mutations. Cell cycles would be unable to be stoped and tumor would keep increasing.
A lot of receptors are G protein coupled. So it is going to be really helpful to alter and make G protein receptors to be inactive. Most if these kinases go through means of phosphorylation and dephosphorylation. Targeting these would cause disruption in signal transduction in cells with cancer
