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.

the wolf population on isle royale fell to just twelve animals after the accidental introduction of canine parvovirus. years later scientists discovered that the skeletons of dead wolves had a high level of deformities in the pelvis and tail bones. how would you explain this finding
Answer:
Genetic drift caused fixation of deleterious alleles that impaired bone development.
Explanation:
With a low population, the effects of parvovirus will have a lasting impact on future generations as the alleles are less likely to be bred out of the population.

Edge Tip: Answers do not mix or change.
The best pair of tools that Silus should use in this experiment is: c. an electronic temperature probe and computer.
What is a temperature probe?A temperature probe can be defined as a scientific instrument (sensor) that is designed and developed for the measurement of the degree of coldness or hotness (temperature) of any physical object.
This ultimately implies that, an electronic temperature probe and a computer are the best pair of tools that Silus should use in this experiment, so as to generate a graph of the temperature values over time.

A scientist wants to test whether the pH, salinity, or temperature of seawater impacts coral
development. He sets up an experiment with three conditions:
Aquarium 1: Normal pH, normal salinity, normal temperature
Aquarium 2: High pH, high salinity, high temperature
Aquarium 3: Low pH, low salinity, low temperature
What factor would improve experimental design the most?
Eliminating Aquarium 1 since it only uses normal conditions
Testing one variable at a time and keeping the other two variables constant
Using one aquarium and changing the variables from day to day
Setting up the variables on a gradient in each aquarium
Answer: Testing one variable at a time and keeping the other two variables constant

Describe the type and ratio of organisms you would expect to find in a lake in a national park. give evidence to support your answer
Answer:
Algae would be the organism in greatest proportion in a lake in a national park.
Explanation:
A lake in a national park would have algae proliferation, which would be the largest organism in that lake. This is because a lake in a national park is subjected to great incidence of sunlight and large amounts of oxygen. This would facilitate and stimulate the reproduction of algae on a large scale, causing them to develop in the substrate, stones, pebbles, and in the water itself.
Why is the earth's gravity stronger than the moon's gravity? A:The moon is so far away from earth. B:The earth is more massive than the moon C:The moon has no mass. D:The earth has a larger volume than the moon.
Answer:
A and B
Explanation:
Gravity relies on both mass and distance
The reason the earth's gravity stronger than the moon's gravity is B. The earth is more massive than the moon
How is the earth gravity stronger ?Gravity is a force that attracts two objects with mass towards each other. The more mass an object has, the stronger its gravitational pull.
The distance between two objects also affects the strength of gravity. However, the distance between the Earth and the Moon is not large enough to significantly weaken the Earth's gravitational pull.
The Earth has a mass of about 5.972 × 10^24 kilograms, while the Moon has a mass of about 7.347 × 10^22 kilograms. This means that the Earth's gravity is about 6 times stronger than the Moon's gravity.

Which atom has two unpaired electrons in the outer valence
shell?
O helium
hydrogen
Oxygen
Olithium
Answer:
Oxygen
Explanation:
The electrons present in an atom are arranged in shells or orbitals. The electrons are filled into these shells based on their energy levels with those shells closest to the nucleus filled first as they have the lowest energies.
The arrangement of electrons around the nucleus of an atom is known as electronic configuration. The outermost electron shell of an atom is known as a valence shell shell and the electrons found in this shell are known as valence electrons. The electrons usually exist in pairs. The first shell can only contain two electrons; the second shell can contain 8. the electrons are singly filled first before pairing occurs.
The electronic configuration of the atoms of the elements in the option are as follows:
Helium : 1s² ; valence electrons are 2 which are both paired
Hydrogen: 1s¹ ; valence electron is 1
Oxygen : 1s²2s²2p⁴ ; valence electrons are 6 wit two unpaired electrons
Lithium : 1s²2s¹ ; valence electron is 1
Helium has two valence electrons but they are paired as its 1s shell can only contain a maximum of two electrons.
Oxygen has 6 valence electrons. Two of these electrons are paired while the other two are unpaired.

In our neighborhoods we have garbage people that come around and
collect garbage and waste at you home. What does that inside of the cell.
Answer:
The answer is lysosomes
Explanation:
Lysosomes are membrane bound organelles that contain degradative/digestive enzymes which are used to digest/degrade/break down unwanted or worn out cellular organelles through a process known as autophagy.
The reason the answer is lysosomes is because the waste (unwanted or worn out organelles) use to be a useful part of the home (cell), however, there is another organelle responsible for absorbing and neutralizing toxins in the cell; it's called peroxisomes
