Answer:
d. all of the above
Explanation:
All of the given choices contribute to the elevated level of carbon in the atmosphere.
This is one of the leading cause of climate change.
Greenhouse emissions from the surface is a huge problem which originates from increasing the release of these gases into the atmosphere. Carbon dioxide is one of the greenhouse gases, and it is the main component of the emissions. Deforestation involves the removal of trees from the earth surface. Trees naturally removes carbon from the environment. They use the carbon to manufacture their own food. Human activities such as industrial processes, burning of firewood for cooking, etc. all contributes significant amount of carbon into the atmosphere.Describe the path that air takes as it enters and passes through the human respiratory system
Answer: The pathway of air in the respiratory system starts with the external organs of the nose and mouth. Nose: Air is inhaled through the nostrils (and sometimes through the mouth) where it is filtered by the hairs and cilia to remove dust particles and moistened. The nasal cavity also moderates the temperature of the inhaled air.

1) Complete the diagram of the cell cycle by writing the names of
each of the four phases.
Answer: Verified by: imsobored100013
Explanation: There's no explanation for this answer if need of help just reply to this answer.
Hope this helped you :)
There are four phases in the cell cycle. Thus, the four phases are the G1 phase, S phase, G2 phase, and M phase.
What is the cell cycle?Chromosomes and other cell components duplicate to create two copies of themselves over the course of the cell cycle. Following this, the cell divides into two daughter cells, distributing one copy of the duplicated material to each.
G1, S, G2, and M are the four distinct stages of the cell cycle. DNA replication takes place during the S or synthesis phase, and the cell divides during the M or mitotic phase. The other two phases, G1 and G2, sometimes known as the "gap phases," are equally significant but less striking. Further M phase is divided into prophase, metaphase, anaphase, and telophase.
Thus, the G1 phase, S phase, G2 phase, and M phase are the four main phases in a cell cycle.

D
Explanation:
all of them are ecosystems:
Lakes/Ponds are a prime example of lentic ecosystems
Fishtanks are are described as a closed artifical ecosystems
Prairies are unique ecosystems that are dominited by grass and other plants.
Answer:
the total amount of matter
Explanation:
In a closed system, the total amount of matter remains the same as it is transferred between organisms and the physical environment, even though its location or form changes.
When one organism consumes another, this matter can change form, but it does not disappear. Eventually, the matter is broken down by decomposers and deposited in the ecosystem's soil, where it can be used by plants. From there, it is able to begin the cycle all over again.

If the herbivore population in an ecosystem increased what would most likely happen to the size of the carnivore population
Answer:
the carnivore population(s) would increase because their amount of food would increase also

Possibly increase
Explanation:
Since there would be an increase of the herbivore population, the carnivores would have more to eat providing more food for their young.
How much energy is transferred up through the trophic levels from primary producer to
primary consumer?
Answer:
On average, only about 10% of the energy stored as biomass in one trophic level—e.g., primary producers—gets stored as biomass in the next trophic level—e.g., primary consumers. Put another way, net productivity usually drops by a factor of ten from one trophic level to the next.Examples of self-duplicating structures are the

This model of the cell cycle includes two arrows that each represent a process in the cycle.
Arrow 2
G, phase
Arrow 1
s phase
G phase
What do the two arrows represent?
F Arrow 1 represents prophase, and Arrow 2 represents interphase.
Arrow 1 represents mitosis, and Arrow 2 represents meiosis.
H
Arrow 1 represents interphase, and Arrow 2 represents mitosis.
J Arrow 1 represents meiosis, and Arrow 2 represents prophase.
Answer:
Arrow 1 represents interphase and arrow 2 represents mitosis
Explanation:
The cell cycle is generally divided into two phases:
the interphase, andthe M or mitotic phaseThe interphase represents the period between the telophase of one cell division and the metaphase of another. This is the period the cell uses to prepare itself for active division. It takes up a large chunk of the cell cycle and it is further divided into:
the G1 phase which represents the period of cell growth and increase in volume,the S phase which represents the period during which DNA is synthesized, andthe G2 phase which represents the period during which protein is synthesized.The mitotic phase represents the period of active division. It is further divided into the prophase, the metaphase, the anaphase, and the telophase.
Hence, the first arrow (1) of the model represents the interphase while the second arrow (2) represents the mitotic phase.
Answer: arrow 1 represents interphase and arrow 2 represents mitosis.

given the following DNA strand which of the following is it’s complementary MRNA? GGACTGATT
A. C C U G A C U A A
B. C C T G A C T A A
C. G G A C T G A T T
D. T T A G T C A G G
The following DNA strand "GGACTGATT" has the complementary mRNA strand "CCUGACUAA". Thus, the correct option is A.
What is mRNA?An mRNA is a type of RNA which is found inside cells. mRNA is also known as messenger RNA. The mRNA molecules carry genetic information which is required to make proteins in the cell. They carry the information from DNA in the nucleus of the cell to the cytoplasm where the proteins are synthesized.
The mRNA synthesized complementary to the sequence of DNA strand can be determined. As A base pairs with U and vice versa and C base pairs with G and vice versa. Thus, the sequence of mRNA synthesized from the DNA sequence "GGACTGATT" will be "CCUGACUAA".
Therefore, the correct option is A.
