What is the relationship between light intensity and gas production?
Answers
Answer:
As light intensity increases (distance between lamp and plant decreases) the volume of oxygen (or the rate of bubble production) increases. This indicates that the rate of photosynthesis increases with light intensity. However, at sufficiently high levels of light intensity, the rate oxygen evolution remains constant.
Why do bones, shells, and teeth make up most of the fossils that have been found so far?
because bones, shells, and teeth are easier to find
because most organisms have bones, shells, and teeth
because bacteria break down bones, shells, and teeth the fastest
because bones, shells, and teeth decay slower than other body parts
Answers
Answer:
the last one
Explanation:
For an organism to become a fossil, it must not decompose or be eaten. ... When an organism is buried quickly, there is less decay and the better the chance for it to be preserved. The hard parts of organisms, such as bones, shells, and teeth have a better chance of becoming fossils than do softer parts.

The study of a living being is called biology.
The correct answer is B.
The arrangement of a species in their respective hierarchy level is called taxonomy. The different levels in which the group of species is placed are called hierarchy levels.
The small or negligible changes in an individual are called microevolution. These changes have hardly any impact on the physical and chemical behavior of the species.
Hence, the correct answer is B that is specified.

Origin and Expansion of the Universe Lab Report
Introduction
Scientists have established a timeline of events after the Big Bang, based on astronomical observations and our understanding of the physical laws of the universe, such as gravity and the speed of light. In this lab activity, you will gather evidence to support the Big Bang theory.
Problem:
How can models demonstrate theories of our expanding universe?
Hypothesis:
Review the virtual lab demonstration in the lesson and stop the video when prompted to formulate a hypothesis. Hypothesize (or predict) what will happen to the distances between the labeled circles when you blow up the balloon ¼ full, ½ full, and ¾ full. Remember to include independent and dependent variables in your hypothesis.
The carbon dioxide represents how galaxies will spread out.
Materials:
Watch the virtual lab demonstration video within the lesson. No additional materials are needed.
Variables:
For this investigation:
List the independent variable(s):
List the dependent variable(s):
List the controlled variable(s):
Procedures:
1. Watch the virtual lab demonstration video within the lesson and record your observations in Table 1.
2. Using your expanding universe data from Table 1, construct a line graph using the volume of the below on the X axis and the distance between points on the Y axis. Be sure to include units and add titles to the graphs. Refer to the graph example and graphing tutorial in the lesson if needed.
3. Complete the Questions and Conclusion section of the lab report.
Data and Observations:
Table 1: Expanding Universe Observations
Galaxies Distance: Uninflated balloon (centimeters)
Distance: ¼ full (centimeters) Distance: ½ full (centimeters) Distance: ¾ full (centimeters)
A to B
A to C

Construct a line graph using the expanding the universe data from table 1. The volume will be plotted on the x-axis. The distance between the points will be plotted on the y-axis. Be sure to include units and add titles to the graph. Refer to the graph example and graphing tutorial in the lesson if needed.
Place your graph here.
Questions and Conclusion
1. How does the density and distribution of your “stars” change as the balloon expands?
2. How does your expanding balloon model represent an expanding universe?
3. What are some shortcomings of using this model as a replica of universe expansion?
4. How does the model you created help to show that the Steady State theory is inaccurate?
5. Suggest a way that a scientist could create an even more accurate model of universe expansion.
6. What will happen to the gravitational force between stars as the universe continues to expand?
In conclusion, how did your prediction of distances between points compare to your experimental results?
Answers
Answer:
this is for number 6
Explanation:As the universe continues to expand, the gravitational force between the stars will decrease the farther apart they become.
Answer:
1. As the balloon begins to expand, the volume will increase resulting in an increase in the density.
2. Each of these dots will represent something similar to a galaxy. When a balloon is inflated, the dot that represents it will begin to move away from the rest since the rubber is stretching the space that is in between them.

Answers
A baker has created a new strain of yeast which contains no cytochrome c gene and no cytochrome c protein. this will affect what the yeast strain can do to obtain energy. what will this yeast strain do more of compared to a normal strain
Will this new strain of yeast obtain more or less free energy from glucose in its growing medium?
Answer: Less because cytochrome c is key to the electron transport chain.
Explanation:
The Cytochrome c is an essential component of the electron transport chain. Without this there will be no oxidation and reduction of iron atom will take place which could convert the ferrous ions to ferric ions. Thus the entire process of electron transport chain and energy production in the form of ATP will be compromised. So, there will be no production of energy in the anaerobic fermentation by yeast.
Answer: C. Fermentation
Explanation: The yeast strain will do more fermentation because the cytochrome c protein is what gives the yeast energy and ATP. Without this gene, the yeast strain will need to find a different way to make energy, like fermentation.

Answer:
C).plowing land without replanting
Explanation:
When plowing is carried out without replanting, the topsoil is destroyed.
Top soil refers to the outermost part of the earth's crust upon which plants grow. All planting activities occur on the topsoil. The structure of the topsoil is very important in its support of plant growth.
Plowing is one of the important planting activities. However, If plowing is carried out without subsequent replanting, the topsoil is destroyed.

You are conducting a twin study to estimate the heritability of a particular trait and have found that monozygotic twins have a concordance of 75%. Using ONLY this information, does this trait show high, low, or unknown heritability? Write no more than two sentences to justify your conclusion, and/or specify how to use additional information to determine heritability. ITRE
Answers
Answer:
The correct answer is "high heritability".
Explanation:
Concordance, is a term used in genetics to describe the probability that one of the twins have certain trait if his brother certainly has it. A high percentage of concordance, such as 75%, is translated into high heritability since monozygotic twins have identical genomic sequences. Additional information to determine heritability will be to study the exposure to similar environmental conditions, since environment can also affect the presence of certain traits.
