Am I right? A scientist makes a discovery that suggests a hominid species created and used relatively sophisticated tools. The scientist decides to publish his findings. Which of the following sources would be regarded as the most reliable? A scientific magazine article A college or university website A film on anthropology A journal reviewed by peers

Answers

Answer 1
Answer: The discovery should be first published in a journal to be reviewed by other scientists to ensure that it is correct/repeatable. After this, the discovery would most probably be reported in scientific magazines and then in newspapers, important discoveries would probably be reported by newspaper quickly though which leaves the potential for a discovery to be untested and incorrect.
Answer 2
Answer: ermm i mean a journal reviewed by peers you mean by other professionals working into that field?  Everything else seems to be correct i would do a little more research on that.

What would be an immediate effect of the construction of roads and parking lots on the transfer of energy from producers to consumers in an ecosystem? A. a decrease in the number of producers. B. a decrease in the number of consumers. C. an increase in the number of producers D. an increase in the number of consumers.

Answers

An immediate effect of the construction of roads and parking lots on the transfer of energy from producers to consumers in an ecosystem would be a decrease in the number of producers. This is because the producers need to live in the soil/land that was once not developed.

Answer:

The correct answer would be A. a decrease in the number of producers.

Human activities like construction of roads, parking lots, buildings et cetera lead to the deforestation due to which producers like grass, plants, trees, et cetera are removed from the area.

Thus, the number of producers is adversely reduced.

Consequently, less amount of mass and energy are available at a primary trophic level.

Question 5 of 10An engineering team has a goal of developing a bicycle frame that is both
lighter and stronger than previous models that they can sell at a higher price.
Which statement describes how a risk would be factored into a cost-benefit
analysis?
A. The cost of the materials to make the frames would be added to
potential improvements in consumer safety.
B. A reduction in employee safety would be added to the increase in
sales of the bicycle frames.
C. The ecological damage of mining the materials would be
subtracted from the profits made by selling the bicycle frames.
D. The money spent manufacturing the frames would be subtracted
from the profits made by selling the bicycle frames.

Answers

Cost-benefit analysis has been defined as the approach used to evaluate the advantages and disadvantages of the choices. The ecological damages must be subtracted from selling profits. Thus, option C is correct.

What is the cost-benefit analysis?

Cost-benefit analysis has been defined as the estimation of the cost and the profits in economical terms. It allows the determination of the monetary benefit gained by the manufacturing, production, and selling of the products.

To manufacture the bicycle frame the monetary benefit can be estimated by subtracting ecological damages for material mining from the profits earned by selling the frame of the bicycle. It gives the idea of how much it cost and benefits the maker.

Therefore, option C. (profits - ecological damage) gives a cost-benefit analysis.

The anglerfish is a type of saltwater fish with an interesting method of catching prey. It lives deep in the oceans, where both light and food are scarce. A "light" glows on a filament right over an anglerfish's mouth. This glow is created by bacteria that live inside the fish. The bacteria are bioluminescent, which means that they produce light. When other fish see this bright glow—a rare thing in the dark waters—they come close to investigate and eventually become dinner. Anglerfish rely on _________ their food. Options: a. Cultivating b. Defending c. Attracting d. Pursuing

Answers

Answer:

C. Attracting

Explanation:

The "light" attracts prey to the anglerfish.

How are DNA and chromosomes related to each other

Answers

DNA contains the instructions, genes, to make proteins that tell what genetic traits the person will have. The DNA along with the proteins make up the chromosomes. The chromosomes are then passed on to the offspring, and with the DNA inside the chromosomes and translation of the genes, its traits are decided.

A researcher may claim a causal relationship between variables if one variable influences another

Answers

Answer:

false

Explanation:

Based on the information provided within the question it seems that this statement is false. Two variable only have a casual relationship if one of the variables causes the other one to exist, which does not seem to be the case in this situation. Instead this situation can be considered as a correlated relationship as a change in one variable influences the other.
