Identify the bonds formed between RNA nucleotides by RNA polymerase.
A. Ester
B. Glycosidic
C. Peptide
D. Phosphodiester
Answer:
D. Phosphodiester
Explanation:
Just as the DNA polymerase serves as a catalyst in the replication of the DNA, so does the RNA polymerase speed up the formation of the RNA. RNA polymerase performs its function of linking nucleotides when the phosphodiester bonds are formed in the 5' to 3' sequence. Nucleoside triphosphate precursors such as the Adenosine triphosphate, Cytosine triphosphate, and Guanosine triphosphate serve as the substrates that allow the formation of the RNA molecule.
When the RNA polymerase unwinds the double helix structure of the DNA found before the active site where the polymerization will occur, substrates can then pair themselves in a complementary form.

During one year, seven coyotes in a population die. Eight immigrate into the population, but none emigrate. If the overall population growth is 13 coyotes, what was the birth rate of coyotes during the year? Use this formula: population growth = (birth rate + immigration) – (death rate + emigration) 7 11 12 15
Answer:
Death rate= 7 coyotes
Immigration= 8
Emigration= 0
Population growth= 13
Let’s suppose that the birth rate for the given population is x.
Population growth = (birth rate+immigration) - (death rate+emigration)
13=(x+8)-(7+0)
13=x+1
Move the variable to the left side and change its sign.
-x+13=1

Which of the following is not a line of evolutionary evidence supported by empirical evidence?
a. How similar DNA is between organisms
b. The length of the organism’s life
c. Where fossils are found
d. How similar the organisms were as embryos
Answer:c where fossils are found
Explanation:
Where fossils are found is not a line of evolutionary evidence supported by empirical evidence. Therefore, option C is correct.
What are fossils ?Any surviving remains, impression, or evidence of a once-living thing from a previous geological epoch is referred to as a fossil. Examples include exoskeletons, bones, shells, animal or microbe imprints in stone, items preserved in amber, hair, petrified wood, and DNA traces. The fossil record is the collection of all fossils.
Shells, bones, animal or microbe imprints in stone, exoskeletons, items preserved in amber, petrified wood, coal, hair, oil, and DNA traces are a few examples of fossils.
The majority of fossils are created when a living thing (such as an animal or plant) dies and is swiftly buried by sediment (such as mud, sand or volcanic ash).
Thus, option C is correct.

Answer:
1. an electrical nerve impulse sent by nerve fibers to the central nervous system for interpretation. Action potential.
2. neurons that detect chemicals such as those found in food. Chemoreceptors.
3. type of eyes many arthropods have; eyes that protrude outward and consist of many lenses. Compound eyes.
4. the structure that gives the response to an environmental change. Effector
5. neurons that detect electrical fields. Electroreceptors.
6. secretion of hormones into the blood stream to affect distant processes. Endocrine.
Explanation:
An action potential is a change in the internal charge of a cell due to depolarization. These changes allow the transmission of a message from any part of the body to the central nervous system. The central nervous system will interpret the message and will give a response.
There are different types of receptors in our bodies. Chemoreceptors are the ones that detect chemicals and produce an action potential or a neurotransmitter. These receptors respond to chemicals. Another type of receptor is the electroreceptors. They detect electrical fields and are only on the skin of aquatic animals.
Compound eyes have a large number of ommatidia. As a result, the anthropods with this type of eyes have a large view angle. In other words, every ommatidium sees an image, and the final product is a combination of all of them.
The effector is the structure that gives an answer once an affector has sent the message to the nervous system that there was a change in the environment.
There are different kinds of secretions, autocrine, paracrine, and endocrine. In the endocrine secretion, the gland secrets hormones into the bloodstream so that they can travel long distances up to their target cell, which is far from the gland.

Explanation:
Into what kingdom would each of the following be classified: Unicellular prokaryotes that live in dust. ______________________ Unicellular eukaryotes that line in pond water. _____________________ Multicellular eukaryotes that live all over the planet and consume food. ______________________ Unicellular prokaryotes that live in volcanic ash. _________________________ Multicellular eukaryotes that have cell walls and are heterotrophic. _______________________ Multicellular eukaryotes that have cell walls and are autotrophic. ________________________
Answer:
Unicellular prokaryotes that live in dust: Eubacteria
Unicellular eukaryotes that line in pond water: Protista
Multicellular eukaryotes that live all over the planet and consume food: Anamalia
Unicellular prokaryotes that live in volcanic ash: Archaebacteria
Multicellular eukaryotes that have cell walls and are heterotrophic: Fungi
Multicellular eukaryotes that have cell walls and are autotrophic: Plantae
Explanation:
Prokaryotic organisms can be classified into two groups: Eubacteria and Archaebacteria. Eubacteria (i.e.,“true” bacteria) are unicellular prokaryotic microorganisms that live in normal environmental conditions. On the other hand, Archaea (Archaebacteria) are prokaryotic older organisms that thrive in extreme conditions (in this case, volcanic ash). Moreover, eukaryotic organisms can be classified into four kingdoms: Protista, Plantae, Fungi and Animalia. Protista are unicellular eukaryotes that live in different aquatic environments (i.e., oceans, ponds, streams, etc). Animals are multicellular, mobile, heterotrophic (i.e., organisms that cannot produce its own food) organisms whose cells lack walls. Fungi are heterotrophic organisms that acquire their food by absorbing dissolved organic compounds, whose cells have cell walls (but they lack chloroplasts). Finally, plants are multicellular autotrophic (i.e., organisms that produce their own food) organisms whose cells contain walls and chloroplasts (to produce food by photosynthesis).

The diagram shows the same type of molecules in area A and area B.
With the passage of time, some molecules move from area A to area B. This movement is the result ot the process of
1. phagocytosis
2. pinocytosis
3. diffusion
4. cyclosis
Answer:
3. diffusion, because molecules are moving from a high concentration(A) to a low concentration(B)
Diffusion is the net flow of matter from a location of high concentration to a region of low concentration as a result of the random mobility of molecules. Both stopping and reversing this process are not possible. Thus, option C is correct.
What are the main mechanism in diffusion process?The molecules' kinetic energy causes random motion, which causes diffusion. This mechanism happens in simple diffusion without the help of a carrier protein.
The molecules travel from an area of high concentration to an area of low concentration due to their random mobility.
Chemicals flow across the plasma membrane from areas of high concentration to areas of low concentration in cells to maintain an equilibrium (balance) of internal substances.
This implies that if there are more items inside the cell than outside, they will go outside and vice versa. It happens when the medium around the cell contains more water than the cell itself.
Therefore, This movement is the result of the process of diffusion.

predict if a coelomate or an acoelmate would be larger
Answer:
Explanation:
A coelom is a hollow space surrounded by tissues. The basic structure of most animals comprises three tissue layers, an interior endoderm and an exterior ectoderm that are separated by a mesoderm. Typically, the endoderm forms the innermost digestive tract, the ectoderm the outermost skin layer, and the remaining internal organs are formed from the mesoderm. In derived animals, the endodermal tube is suspended from the dorsal and ventral surfaces by mesoderm, so as to leave open coeloms that allow circulation of fluids. Advanced circulatory systems develop from these coeloms.
The poles of the planet experience many months in a row when the Sun
never sets. Why are the North and South poles still relatively cold during
these times?
The missing options are:
A. The Sun is still low in the sky, so the solar intensity is low.
B. The Sun is low in the sky, so the solar intensity is high.
C. The poles were cooling for six months with no sunlight, and it takes a long time to warm up.
D. Both A and C are correct.
The correct answer is D. Both A and C are correct.
Even though the Sun never sets for many moths in the North and South poles, these are still cold because for them to warm up:
The Sun's rays should impact directly on the poles, as it happens with the rest of the Earth during summer.As they are large pieces of land, it takes a lot of time to warm them, and it takes more than six months to do so, even more with the Sun no impacting directly on them.In conclusion, the poles are cold because they are never positioned directly in front of the Sun since the Earth has an inclined axis. As a result, the rays directly impact the rest of Earth during its yearly journey around the Sun, resulting in high solar intensity, with high temperatures, during summer. Besides, as the Sun's rays have a very low intensity in the poles, they could never warm up these parts of Earth in six months; they need more time.

A trait that does not offer members of a population a great advantage will most likely
A. increase the reproductive rate in successive generations
B. decrease in frequency in successive generations
C. appear at the same frequency in successive generations
D. undergo a series of mutations in successive generations
A trait that does not offer members of a population a great advantage will most likely decrease in frequency in successive generations. Thus, option B is correct.
What is theory of natural selection?
According to Charles Darwin in his theory of natural selection, organisms must compete for scarce resources. Only the fittest can survive. The fittest are organisms that have undergone the required genetic changes that increases their chances of survival. They pass on these genetic changes to the next generation or offspring.
When availability of food decreases, organisms begin to change genetically as they struggle for scarce resources thereby leading to variation in a population. All organisms must compete for survival. Natural selection continues to occur even today.When organisms struggle to survive, they usually mutate to increase chances of reproduction.
Therefore, A trait that does not offer members of a population a great advantage will most likely decrease in frequency in successive generations. Thus, option B is correct.
