Answer:
They use spears.
Explanation:
The hunting method that the Clovis people used for killing the large animals is the use of spears. These spears have a pointed head which easily penetrate in the body of these large animals and kill them in a very less time. They mostly hunt big animals in groups which make easier the hunting of animals. In this period when the Clovis people were present, extinction of mammoths, giant sloth and bison in North America occurs due to hunting and climate change.
Answer:
They used spears to kill a bunch of animals :3

Question 1
Which structure is outside the nucleus of a cell and contains
DNA?
A
chromosome
mitochondrion
B
gene
D
vacuole
Answer:Chromosome
Explanation:
Mitochondria are basically power generators, thats it.
Vacuole acts as a sewage system, dumping excess water and material.
A chromosome is something that makes up a gene, so that cant possibly be right.
Answer:
mitochondrion
Explanation:
The mitochondrion contains mitochondrial DNA which goes back to the endosymbiotic theory if you remember that.

Why is chalk used on blackboards?
15. Preservation focuses mainly on preserving resources so that they can be used by people a. True b. False
Answer:
b. False
Explanation:
Preservation stands for preserving or sustaining what already exists. aimed at preserving natural resources in their original environment, free from human interference. It stands for securing an object from harm or decay while preserving its nature or state at the same time. Preservation of natural resources does not only benefit humans but also rejuvenates the wildlife and thus gave time for the Earth to breathe and regain its natural form.

Select all that apply. Which of the following are characteristics of eukaryotes? single- or multi-celled structure no distinct nucleus membrane-bound organelles cell(s) larger than prokaryotes
Answer:
They can be single or multicellular and they are bigger than prokaryotes. They have a distinct nucleus and membrane-bound organelles, so that option would be incorrect. I hope this helped.
Explanation:
3. In a field of sugar beets in Georgia the net primary productivity is 120 grams/m^2/day, and the
respiration loss is 25%. The insolation energy is 800 calories/cm^2/day, and one gram of beets is
equivalent to 2,000 calories.
a. Find the gross productivity of the sugar beets.
b. Using the NPP, calculate the efficiency of photosynthesis for the sugar beets.
Answer and Explanation:
Available Data:
1 gr beets = 2,000 cal NPP = GPP – Respiration = 120 grams/m2/day NPP= Net primary productivity of a system GPP= Gross productivity of the producers Respiration loss 25% of NPP Insolation energy is 800 calories/cm2/day % Efficiency of Photosynthesis = (NPP/Insolation Energy) X 1001) Find the gross productivity of the sugar beets.
We need to calculate the GPP, which equals NPP - Respiration rate. The respiration loss is 25% of the NPP. This is:
100% NPP--------------- 120 g/m²/day
25% NPP ----------------X = (25 x 120)/100 = 30 g/m²/day
Now that we know the values of NPP and respiration rate, we can calculate the GPP.
GPP = NPP - Respiration
GPP = 120 (g/m²/day) - 30 (g/m²/day)
GPP = 90 g/m²/day
GPP = 0.009 g/cm²/day
2) Using the NPP, calculate the efficiency of photosynthesis for the sugar beets.
% Efficiency of Photosynthesis = (NPP/Insolation Energy) X 100
We know the NPP, but this value is calculated in g/m²/day, while the Insolation energy is in g/cm²/day. We need to calculate the % Efficiency of Photosynthesis in cm. To do that, we must transform the information.
So if 1 m² = 10,000 cm², then:
10,000cm²----------120 grams/m²/day NPP
1 cm²---------------- (1 x 120) / 10,000 = 0.012 grams/cm²/day NPP
We also know that 1 gr beets = 2,000 cal, and that the Insolation energy is 800 calories/cm²/day
So we need to transform Insolation energy from calories/cm²/day to grams/cm²/day, so:
2,000 calories ----------------- 1 gr beet
800 calories/cm²/day---------X = 0.4 gr beet.
% Efficiency of Photosynthesis = (NPP/Insolation Energy) X 100
% Efficiency of Photosynthesis = (0.012 (gr/cm2/day) /0.4 (gr/cm2/day)) X 100
% Efficiency of Photosynthesis = 3 gr/cm2/day
