One summer, the anthropologist returns to the site at the start of a new field season. He discovers that the same local residents who he hires in the summer have allowed their cattle to graze on the site over the winter while he was gone. The cattle have trampled some of the site and have permanently damaged the irreplaceable fossil materials. How should he proceed?
Answer:
The remaining part was not damage so the anthropologist can proceed his research.
Explanation:
The anthropologist should continue his work on the remaining part of the field for its study because the remaining part is not disturb by the animals, only little part of the field was damaged during grazing so the anthropologist can take his information from the remaining field and avoid taking data from the affected field due to damaged was done fossil materials and the fossil materials was not present in its original shape..
At which stage of development does the embryo implant in the uterus?
Answer:
Blastocyst stage
Explanation:
A baby undergoes different stages of development before they become fully matured. It all begins with the process of fertilization which involves a sperm cell coming in contact with an egg.
After a successful fertilization, the fertilized egg travels down to the uterus where it undergoes series of cell division till it becomes a stack of arranged cells known as the blastocyst.
During the blastocyst stage, the embryo fastens itself to the edge of the uterus, this process is known as implantation.
Hence, the embryo implants in the uterus during the blastocyst stage.

Which clue can be used to identify a chemical reaction as a combustion reaction? Oxygen is a product. A hydrocarbon reacts with oxygen. Water and carbon dioxide react. The reaction involves ions.
Answer:
A hydrocarbon reacts with oxygen
Explanation:
The clue that can be used to identify a chemical reaction as a combustion reaction from the options would be if a hydrocarbon reacts with oxygen.
Basically, a combustion reaction is a kind of reaction involving oxygen and another reactant with energy being released in the process. The energy is usually in the form of light and heat.
Thus, following the definition:
Oxygen is rather a reactant, and may not be a product in combustion reactionsWater reacting with carbon dioxide is not a combustion reactionReaction involving ions may not be a combustion reactionThe only reaction that may identify as a combustion reaction is, therefore, the one involving hydrocarbon and oxygen.

In Oxygen molecule O2, stability is gained through sharing of
Answer:
Trees and plants.
Explanation:
Trees give us oxygen and plants get rid of carbon dioxide and remake it as oxygen.
In the Oxygen molecule O2, stability is gained through sharing of two pairs of electrons with a single neighboring atom.
What is the sharing of electrons?The sharing of electrons gives rise to the formation of covalent bonds between two atoms. Atoms will be covalently bonded in order to gain more stability. During the process of sharing electrons, they are simultaneously attracted by the two atomic nuclei.
The stability of oxygen molecules is gained through the help of non-polar covalent bonds. This means that there is no difference in electronegativity of bonded atoms.
The valence shell of oxygen has six electrons, so they need two more electrons in order to fulfill its octet and maintain stability. The sharing and paring of electrons between two or more atoms construct a bond known as covalent bonds.
Therefore, in the Oxygen molecule O2, stability is gained through sharing of two pairs of electrons with a single neighboring atom.

How is it possible that all animal life depends on the chloroplast for energy
chloroplast contains chlorphyll . Chlorophyll is used in photosynthesis to produce glucose . (photosynthesis is a process where green plants manufacture simple sugar (glucose) from carbondioxide and water by using sunlight ) 6co2+6h2o=c6h12o6+6o2
if theres no chloroplast no glucose will be produced so animals will have no energy. chloroplast must be present in order of photosynthesis to take place and produce glucose , when plants produce glucose animals get the energy needed by feeding on plants (in simple words animals eat the sugar that plants have produced )

A 7.2 × 10–5 C charge has an electric potential energy of 1.08 × 10–2 J. The electric potential, to the nearest whole number, is V.
Answer:
150.
Explanation:
On edge
The electric potential, to the nearest whole number is 150 V.
What is the electric potential energy?The electric potential energy denoted by U is proportional to the charge and inversely proportional to the distance between the point where its is brought from infinity to the charge.
U = kQ₁Q₂/r
For identical charge,
U =kQ²/r................(1)
and the electric potential is given by
V = kQ /r................(2)
Dividing both the equations, we get
U/V = Q
Substitute charge Q = 7.2 × 10⁻⁵ C, Electric potential energy U = 1.08 × 10⁻² J, then the electric potential will be
V = 1.08 × 10⁻² / 7.2 × 10⁻⁵
V = 150 Volts
Thus, the electric potential is 150 Volts.
