An oblique plane is a boundary between the false pelvis and true pelvis, and the circumference is called the pelvis brim.
What is the pelvis?
Basin shape structure supports the spinal column and also protects the abdominal column. pelvic consist sacrum, coccyx, and a pair of hip bones.
The pelvic brim consists sacral segment, iliac, and pubis portion, but ischium is not present in the pelvic brim, the false pelvis and true pelvis boundary is the oblique plan.
The false pelvis is a region of the abdominal cavity but not a region of the pelvic cavity, but the true pelvis contains the bladder, pelvic colon, rectum, and reproductive organ.
Therefore boundary between and true pelvis and false pelvis
an oblique plan having a circumference called a pelvic brim.

1. What are the three components of a nucleotide (Remember only the nitrogen bases
change between nucleotides). Draw all four nucleotides below:
Answer:
adenine, cytosine, guanine or thymine
Explanation:
Nucleotides are made up of 3 parts. The first is a distinct nitrogenous base, which is adenine, cytosine, guanine or thymine. In RNA, thymine is replaced by uracil. These nitrogenous bases are either purines or pyrimidines.
why still humans have hair on body ?
Answer:
Hair is important for maintaining skin health, as each hair follicle has blood vessels, nerves, and fat around it. Hair follicles are rich in stem cells that promote healing of the skin — helpful if you have a cut or wound. Hair also keeps a person warm and protects the skin from sun damage.
Explanation:
this might help
Answer:
See below
Explanation:
Humans have hair on their bodies to prevent infections from entering the body. Lets take nose hair for example, while you breathe in and out threw your nose, any airborne virus may be caught and tangles in your nose hair, thus making it near impossible to enter your body, it is still possible though to enter the body.
Hair is important for maintaining skin health, as each hair follicle has blood vessels, nerves, and fat around it. Hair follicles are rich in stem cells that promote healing of the skin — helpful if you have a cut or wound. Hair also keeps a person warm and protects the skin from sun damage
While humans have developed clothing and other means of keeping warm, the hair found on the head serves primarily as a source of heat insulation and cooling (when sweat evaporates from soaked hair) as well as protection from ultra-violet radiation exposure. The function of hair in other locations is debated.
examine the image shown here. These two species shown are pollinators and the flowering plant that they feed upon. Which statements accurately describe the interaction between these two groups?
A)Natural selection put pressures on the pollinator to increase its fitness over generations.
B)Heterozygote advantage provided a mechanism for species to become better fit for within their environment.
C)Convergent evolution caused the proboscis of the pollinator to mechanically fit with the flower of the other species.
D)The pollen of one species increased the mutation rate of the pollinator species so that they were more adapted to their flower.
E)Coevolution provided a mechanism for these two species to put selective pressures on each other to shape the pollinator structures.
Coevolution refers to the existing relationship between two species, and the selective pressures that each of them imposes on the other. These pressures result in both species evolving together in the same direction.
------------------------------------
When the interaction between two species is so strengthened that each population exerts a selective strength over the other one, simultaneous adjustments occur, resulting in Coevolution. Coevolution is the biological relationship existing between two or more species that interact and adapt to each other. Coevolution is the mechanism by which coadaptation can be explained. Coadaptation refers to reciprocal genetic changes in species that interact. This is due to the selective pressures that each of them imposes on the other. Coadaptation is what can be seen or observed.For coevolution to exist, there must be phenotypic variation and heritability. Coevolution can be specific or diffuse. Specific or strict coevolution involves two species in interaction in which the evolution of each one responds to selective pressures applied by the other species.
The correct option is E) Coevolution provided a mechanism for these two species to put selective pressures on each other to shape the pollinator structures.

Why is DNA found in both the nucleus and in the mitochondria? What is the advantage of
doing this?
AnswerAll multi-cellular life forms have them. In some organisms the DNA that codes for the mitochondrion has been moved into the nucleus and become part of the DNA of the host cell, but in vertebrates the mitochondria keep their own DNA inside themselves.
Explanation:
Answer:
Mitochondria are found in all eukaryote organisms, unlike prokaryotes. Both nucleus and mitochondria have their own DNA. The DNA of mitochondria is called mitochondrial DNA. The mitochondrial DNA helps in the production of ATP that produces energy whereas the DNA in the nucleus is the genetic material of the cell.
Explanation:
The presence of DNA inside the mitochondria is because of the fact that mitochondria are believed to be a primitive bacterium that was consumed by a eukaryote and became an essential organelle of the eukaryotic cell. Today, mitochondria exist only inside a eukaryotic cell serving as the powerhouse of the cell and containing mitochondrial DNA containing 37 genes. Advantaged of DNA in both nucleus and mitochondria:Advantages of DNA found in mitochondria and nucleus are: 13 genes of mtDNA perform the function of oxidative phosphorylation.Other genes help in the formation of tRNA and ribosomes which helps in efficient protein synthesis and production of ATP.The presence of a high number of mtDNA in the cell helps in producing a great amount of energy for the functioning of the cell.For more information:

When neurons/nerves are cut, the cells cannot deliver neurotransmitters. Explain how this may affect the body:
Answer:
Nerve: When a nerve is cut, both the nerve and the insulation are broken. Injury to a nerve can stop the transmission of signals to and from the brain, preventing muscles from working and causing loss of feeling in the area supplied by that nerve.
Neuron: An injury to a neuron can stop the signals transmitted to and from the brain, causing muscles to not work properly or a loss of feeling in an injured area. Nerve injuries can impact the brain, the spinal cord, and peripheral nerves.

You are able to extract mitochondria from the cell and remove the outer membrane. You want to show that the mitochondria can still produce ATP if placed in the right solution. The solution should be isotonic, but at what pH
Answer:
Low PH
Explanation:
The high external acid concentration causes an increase in H+ in the inter membrane space leading to increased ATP production by ATP synthetase.
Mitochondrial production of ATP requires a concentration gradient of H+, with a high concentration at the inter membrane space and a low concentration in the matrix. The inner membrane is impermeable to H+, but the outer membrane of the mitochondria will allow H+ to pass through. Thus, placing mitochondria in a low pH buffer produces a H+ gradient that can generate ATP through ATP synthetase.
Superweeds: Due to new genetic engineering technology, scientists have been able to alter the DNA in corn, soybeans, and cotton to make them resistant to the chemical herbicides used to kill weeds. Consequently, millions of acres of United States farmland have been regularly sprayed with herbicides, leading to the development of a herbicide tolerance in weeds. Producers must now use larger amounts of herbicides and find new, stronger chemicals to fight off the herbicide-tolerant weeds.

2. Light chain is the small polypeptide subunit of an antibody (immunoglobulin).
3. Variable region is the ends of the light and heavy chains
4. Constant region is determines the mechanism used to destroy antigen.
5. antigen binding site is the part of an antibody which recognizes an antigen, the antigen-binding site of an antibody.
6. disulfide bridge are formed by the oxidation of 2 thiol groups within Cys residues and in many extracellular proteins.
7. epitope is the specific piece of the antigen to which an antibody binds. The part of an antibody that binds to the epitope is called a paratope.

A population of birds lives on an isolated island, the Hardy-Weinberg equilibrium would be maintained after several generations due to non-disturbed environment and no human interference.
Climate change is melting the polar ice where polar bears live, the Hardy-Weinberg equilibrium would be maintained after several generations if the melting of polar ice can be recovered or the polar bears go to the suitable place.
