Answer:
The correct answer is - the difference in altitudes.
Explanation:
The hemoglobin in the person of Denver who lives at a higher altitude than the person who lives in Philadelphia will be much higher. This is due to the fact that at higher elevation or altitude atmospheric pressure decreases that causes hemoglobin to stick to the RBCs and that results in less oxygen level in the body.
To compensate for this low level of oxygen levels hemoglobin content need to be higher in people living at a higher elevation.

What is the purpose of using a Punnett square in studying genetics?
A. to determine the probability of an offspring to breed with another of the same phenotype
B. to determine the exact number of offspring having a particular genotype
C. to determine the probability of an offspring having a particular phenotype
D.to determine the probability of an offspring having a particular genotype
The purpose of using a Punnett square in studying genetics is to determine the probability of an offspring having a particular genotype. Thus, the correct option for this question is D.
What is Punnett square?Punnett square may be defined as a type of table in which all of the possible outcomes for a genetic cross between two individuals with known genotypes are determined. It is named after Reginald C. Punnett, who proposed this approach in 1905.
In genetics, Punnett square is extremely utilized in order to predict the possible outcomes of two unknown genotypes. With the help of these genotypes, phenotypes of a specific set of alleles are also determined. The important concept of Punnett square is that it always determines the probability, not the exact number.
Therefore, to determine the probability of an offspring having a particular genotype is the purpose of using a Punnett square in studying genetics. Thus, the correct option for this question is D.

b.Stress fracture
c.Pathologic fracture
d.Greenstick fracture.
The correct answer is c.
Explanation:
A pathological fracture is one produced in a weakened bone as a result of trauma that would not cause such an effect on bones that had their composition, resistance or flexibility properties at the correct levels, that is, a pathological fracture is any loss of bone continuity that occurs in a weakened bone, secondary this weakness to the development of a disease. Endogenous osteomyelitis is a blood-borne bacterial infection that spreads to the bone.

turnips are root vegetables. turnips have been selectively bred from a wild plant called field mustard. field mustard plants do not have big, round roots like turnips. explain how turnips have been selectively bred from field mustard.
can anyone help me out? thx
the turnips have a model called Turnip's model that's why the turnips have been selectivity breed from field mustard.
Turnip is a type of root vegetables that belongs to the mustard family.
Turnips are ready to harvest 40 to 55 days after planting. If harvesting the leaves, they are ready when they reach four to six inches in height. If only harvesting the leaves, cut them from the plant when they reach the desired size, leaving one inch of leaves above the crown of the plant. More leaves will grow in their place.

If you are interested in the evolutionary relationship of animals that have four limbs, which of the following would be the outgroup? Group of answer choices Sharks Ray-Finned Fish Amphibians Crocodiles Dinosaurs
Answer:
First outgroup → Ray-Finned FishesSecond outgroup → SharksExplanation:
The outgroup is the most distant taxonomic group that shares no traits or characters with the lineages of interest, which compose the ingroup. You can compare the outgroup with the ingroup to determine the evolutive relationship and which characters are primitive or derived.
Even though the outgroup shares a common ancestor with the ingroup, this is placed far away in evolution, making the outgroup to be the taxonomic group less related to the other lineages. The lineages in the ingroup share another common ancestor that is more recent in history.
To select the outgroup, you need to focus on what you are interested in. There might be several outgroups, but you should choose the one that is more related or closer to the ingroups. This selection is important because you need to make comparisons to understand the evolution of specific traits.
In the exposed example, we need to focus on animals that have four limbs. Then, we might assume that the ingroup is composed of Amphibians Crocodiles Dinosaurs. Sharks and Ray-Finned Fish do not have four limbs, so they might be considered outgroups.
From these two outgroups, sharks have a cartilaginous skeleton, while Ray-Finned Fishes have a bony skeleton. This fact makes ray-finned fishes more related to the ingroup than the sharks. So,

A diagram shows a potato producing new tubers. Buds on the parent plant grow into stems that grow downwards called stolons. The end of each stolon develop in to new tuber.
1) Give two pieces of evidence which show that this is an asexual method of reproduction.
2) Explain why all the new tubers will be genetically identical.
Answer:
See the answer below
Explanation:
Evidence that shows that the illustration is an asexual method of reproduction:
1. New tubers were produced without any signs of flowering or fertilization
2. Parent plant was produced from a vegetative part ( a tuber).
All the new tubers would be genetically identical because they were produced without fertilization. They all developed from the division of some of the vegetative cells (mitosis) of the parent plant. Hence, they are not only genetically identical with themselves but also with the old tuber that produced the parent plant.
Samantha is being seen today because at approximately 10 a.m. today she experienced a sudden hearing loss in her right ear.

Random Answer = Report
Correct Answer = Brainliest
Answer:
Due to no controlling agent for harmful microbes that causes new pandemic.
Explanation:
The new pandemic leads to imbalance of ecosystem due to biodiversity loss because the absence of antimicrobial agent causes the pandemic. The antimicrobial agent is responsible for the control of harmful microorganism so due to disturbance in the ecosystem, the biodiversity losses occurs and there is no organism which stop or control the population of the harmful organism that causes new pandemic.

Name the process by which sugar moves into cell A - Diffusion
Name the process by which sugar moves into cell B - Active transport.
Glucose tends to move from an area of high concentration to an area of low concentration, a process called diffusion

Answer:
See the answer below
Explanation:
The phenomenon is best explained by the fact that the genetic codes are degenerates. In other words, more than one codon can specify for the same amino acid being carried by the tRNA.
The base-pairing rule between the third nucleotide of a codon and that of the anticodon on the tRNAs loosens off. For example, GUU, GUC, and GUA all specify for the amino acid valine while GCU, GCC, and GCA all specify for alanine.
Discuss the impact of development planning for economic development for a development country like Pakistan under what circumstances a country should go for short term medium term and long term plan (it is a economics question)

There is a great impact of development planning for economic development for a country because this development planning is important for the growth of economy of the country. Without planning, goals of better economy can not be accomplished. A country should go for short term plan in order to solve the economic problem at that time while on the other hand, medium and long term plan is used by the country in order to solve the economic problem completely.
