1. The role of bacteria in the carbon cycle is _________________
(a) breakdown of organic compounds (b) respiration
(c) absorption of nitrogen compounds (d) photosynthesis
Answer:
breakdown of organic compounds
Explanation:
Bacteria are responsible for maintaining the conditions of life as the earth by virtue of their powers of decomposition of plant and animal bodies by which the limited supply by C02 available for photosynthesis is replenished. Thus, they act as decomposers in the carbon cycle.

Using the data from the table, make a graph of the number of atoms remaining after each trial.
Questions
1. How many trials did it take for half of the Virtualium atoms to decay?
1 trial
2. Suppose each trial equals 1,000 years. What is the half-life of Virtualium?
1000 years
3. Suppose each trial equals 1,000 years. After half (50) of the Virtualium cubes were removed from the box, about how long did it take for half of the rest of the cubes to decay?
5000 years
4. Imagine you have a radioactive sample containing both Virtualium and decayed atoms of Virtualium. After analysis, you find it contains 10 atoms of Virtualium and 40 decayed atoms. How old is your sample? (Hint: You must use the half-life of Virtualium determined earlier in the activity.)
It is 8000 years old.

Attached earlobes are a recessive trait in humans. In the tree below, people
with attached earlobes are shaded in. Which best describes the person
labeled X in the tree?
A. A female with no recessive alleles
B. A male with no recessive alleles
C. A male with one recessive allele
D. A female with one recessive allele
Answer:
It would be C
Explanation:
If you look at the tree you can see that one of the male's parents had the recessive allele, and one of the siblings has the ressive allele, the means the male could have the trait but isnt showing it.
A male with one recessive allele describes the person labeled X in the tree.
What is Recessive allele?
In terms of genetics, the term "recessive" describes the connection between an observed trait and the two inherited forms of a gene associated with that feature.
Each gene has two alleles that an individual inherits from each parent. When a characteristic is recessive, both of the (recessive) alleles of the gene that causes the trait must be present for the trait to manifest.
When there is only one copy of an allele, it has no effect at all. This is in contrast to a dominant trait, which can only be expressed when one of the two alleles is present.
Therefore, A male with one recessive allele describes the person labeled X in the tree.

The overall process of photosynthesis can be written as the equation:
A. 6 glucose + 6 water --> 6 oxygen + 6 carbon dioxide + light
B. 6 water + 6 carbon dioxide (+ light) --> 6 oxygen + glucose
C. 6 oxygen + 6 water (+ light) --> 6 glucose + carbon dioxide
Answer:
the overall process of photosynthesis is written by the equation B.
Answer:
B. 6 water + 6 carbon dioxide (+ light) --> 6 oxygen + glucose
Explanation:
In words, the equation may be stated as: Six carbon dioxide molecules and six water molecules react to produce one glucose molecule and six oxygen molecules. The reaction requires energy in the form of light to overcome the activation energy needed for the reaction to proceed.
what animal has the longest lifespan?
Answer:
Ans.The longest living mammal is the bowhead whale, which can live up to 200 years. Also known as the Arctic whale, this animal is big, and lives in cold waters so its metabolism is slow. The record age for bowhead is 211 years.
Some endoliths have lifespan as long as 10000years.
Entre las células, aquellas que presentan cloroplastos con clorofila pueden ser catalogadas como...… A) ...Heterótrofas B) ...Carnívoras C) ...Autótrofas D) ...Herbívoras
Respuesta:
La respuesta correcta es: C) Autótrofas.
Explicación:
La clorofila es un pigmento verde que se encuentra en las cianobacterias y en células vegetales, dándoles a las plantas y algas su característico color. Se encuentra dentro de los cloroplastos.
La clorofila es una molécula de muchísima importancia para llevar a cabo la fotosíntesis, un proceso clave en la vida de las plantas y cianobacterias, ya que es la forma en la que obtienen los nutrientes que requieren para su supervivencia. El hecho de realizar fotosíntesis es lo que convierte a estos seres vivos en autótrofos, lo que significa que elaboran su propio alimento orgánico a partir de sustancias inorgánicas.

A boxer has been jumping rope for an hour. His leg muscles are burning and
he feels weak. Which substance is the most likely
cause of the burning he
feels in his muscles?
Answer:
anaerobic respiration takes place when you demand your muscles to do vigorous work. normally, aerobic respiration takes place but when energy is needed immediately, anaerobic respiration takes place. during anaerobic respiration,the body produces lactic acid, which leads to the burning sensation. your lungs deliver oxygen to the muscles much slower than the rate you need, since you're putting your muscles through an extensive exercise, and this leads to muscle fatigue.

What did the countries that signed the Kyoto Protocol agree to do?
O A. Stop using CFCs
O B. Stop depleting the ozone layer
O c. Reduce greenhouse gas emissions
O D. Ban CO2 use
Answer:
C
Explanation:
The countries that signed the Kyoto Protocol agreed to reduce greenhouse gas emissions (C) particularly carbon dioxide emissions, in an effort to combat climate change.
What is Kyoto protocol?The Kyoto Protocol is an international treaty under the United Nations Framework Convention on Climate Change that was adopted in 1997 in Kyoto, Japan (UNFCCC). The treaty seeks to address the issue of global climate change by establishing targets for reducing greenhouse gas emissions, specifically carbon dioxide emissions, from industrialized countries.
According to the Kyoto Protocol, developed countries must reduce their emissions by an average of 5.2% below 1990 levels by 2012. The protocol has been ratified by 192 countries, and signatories have implemented a variety of policies and strategies to meet their emissions reduction targets, including increased energy efficiency, increased use of renewable energy sources, and the implementation of emissions trading systems. The Kyoto Protocol is a significant step forward in terms of international cooperation and action on the critical issue of climate change.
