Define Physical Properties?
Answer:
A physical property is any property that is measurable, whose value describes a state of a physical system. The changes in the physical properties of a system can be used to describe its changes between momentary states. Physical properties are often referred to as observables. They are not modal properties.
Evaluate the evolutionary benefits of regulating an internal variable, such as body temperature, versus the cost.
Answer:
The benefits of being able to regulate the internal body temperature are many and it is considered a beneficial evolutionary character, since in this way the living organism is better maintained in relation to the environment, and it achieves better balance.
Reptiles cannot control their internal temperature, it depends on the external one, that is why to warm their body they need to be in the sun, and to cool down in the shade or in temperate places.
This is a little evolutionary characteristic since the environment is very changeable and the right or ideal temperature for the organism could not be controlled.
Explanation:
Faced with climatic catastrophes or extreme situations, living organisms cannot depend on the great climatic variants, in very cold situations one enters hypothermia and in very hot conditions the proteins are systematically denatured, entering a thermal shock.

Golgi body
Cell membrane
Centrosome
Nucleus

Mitochondrion
Answer:
1.A Golgi body, also known as a Golgi apparatus, is a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell.
2.The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.
3.The cytocenter or centrosome is a cellular organelle that is not surrounded by a membrane; ... " centrosome- related bodies " (CRBs for centrosome- related bodies) are often seen at ectopic sites.
4.The nucleus is a membrane-bound organelle that contains genetic material (DNA) of eukaryotic organisms. As such, it serves to maintain the integrity of the cell by facilitating transcription and replication processes. It's the largest organelle inside the cell taking up about a tenth of the entire cell volume.
5.A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products.

How fast are you moving relative to the chair relative to the Sun?
The answer to the question of how fast you are moving relative to the chair relative to the Sun would be the same, as you and your chair are effectively moving at the same speed as the Earth.
However, if we assume that you are sitting in a chair and ask how fast you are moving relative to the Sun, the answer would depend on the reference frame. From the perspective of someone standing on the Sun, the Earth (and therefore you and your chair) is moving in an elliptical orbit around the Sun at an average speed of about 30 kilometers per second (67,000 miles per hour). From the perspective of someone standing on the Earth, you and your chair are stationary (ignoring the rotation of the Earth) while the Earth is rotating on its axis and orbiting the Sun at the same speed mentioned above.

b. The positive control tube receives genomic DNA from an insect known to be positive for Wolbachia infection.
c. The positive control tube receives any genomic DNA from a student's sample that is predicted to be infected with Wolbachia.
d. The positive control tube receives water for template DNA.
Answer: c. The positive control tube receives any genomic DNA from a student's sample that is predicted to be infected with Wolbachia.
Explanation:
Positive PCR control can be defined as the control sample that is used as a benchmark for comparison with the results of the PCR or polymerase chain reaction. It comprises of artificial genome or primers. For amplification of microbial DNA synthetic oligonucleotides are used as targets of each primer and a hydrolysis probe is also used. As it is already known that primer as well as hydrolysis probe has the specificity for the DNA strand so it will help in identification of the specific region or sequence in the DNA structure. Wolbachia DNA can be detected if the positive control consists of samples of students affected by Wolbachia that can give indication of whether the Wolbachia species is the same as that of the one which has caused infection.

A lead to T transversion in the second nucleotide of codon 6 of the beta-globin gene causes sickle-cell anemia, hence option D substitution is the correct option.
What is sickle-cell anemia?The beta-globin gene makes hemoglobin S, which polymerizes in the deoxygenated state.
This causes physical distortion or sickling of erythrocytes, containing an A to T point mutation that is the source of the condition.
Therefore, sickle erythrocytes encourage hemolysis and vaso-occlusion, two of the disease's key symptoms, hence option D substitution is the correct option.
