Answer:
B
Explanation:
The total amount of energy in the cosmos has never changed and will never change since it cannot be generated or destroyed, hence option B is correct.
What is energy?This does not imply that energy cannot change forms or even move between objects though it does. Energy may transform from more useful forms into less useful forms, but it cannot be generated or destroyed.
Energy gaining or loss is one of two things that can happen to a substance when it loses or gains energy, either its temperature changes or its condition changes.
Therefore, It turns out that some energy gets transformed into a useless form in every real-world energy transfer or transformation (unavailable to do work), hence option B is correct.

Answer:
B
Explanation:
Experiment tools and methods were not as precise as they are now. Since tech has evolved so has the ways to look at atoms meaning that they will see new and different things.
This atomic model has changed over time. Scientists used the model to make predictions. Sometimes the results of their experiments were a surprise and they did not fit with the existing model. Scientists changed the model so that it could explain the new evidence. And Because more experiments gave more data, theories and models for atoms changed to be more accurate over time.

Describe the relationship between photosynthesis and cellular respiration.
Answer:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

Orange trees planted in a grove or orchard would most likely fall in which category of population distribution?
a.even
b.random
c.clumped
d. density
Answer:
A) Even
Explanation:
got it right on edge :)
Orange trees planted in a grove or orchard would most likely fall in the even category of population distribution. The correct option is a.
What is population distribution?Population distribution is how the population of something, plants, animals, or humans is distributed in specific areas. It specifies where people live or where they are not living.
There are three types of population distribution:
Uniform dispersion - In this distribution, the population is uniformly or evenly distributed in the areas. Even distribution comes under this distribution.Random dispersion - there are no predictable patterns in this dispersion. They are randomly present anywhere.Clumped dispersion - This distribution shows the bunch or group of population is areas then there is no population, and then there is a a bunch of population in another place.Thus, the correct option is a. even.

Which option describes a strong argument against the development of nuclear power? A nuclear power company is proposing a nuclear power plant near a quiet, small waterside town. The company is promoting this development by stating that nuclear power does not produce pollutants.
Answer:
The correct answer is B) The company is promoting this development by stating that nuclear power does not produce pollutants.
Explanation:
Whilst the process of power generation itself does not produce environmental pollutants like fossil fuels which features the emission of carbon monoxide when they are partially combusted, it does leave behind radioactive wastes, in the same way, combusted charcoal or wood leaves ash behind.
The challenge with radioactive wastes is that they are inimical to human health and can remain so for hundreds of centuries.

Which of these DNA sequences will produce the following m-RNA: AGC-UAC-ACU?
Hint: Remember in mRNA Thymine is replaced by Uracil.
A TCG-ATG-TGA
B TCG-TAC-ACT
C TCG-ACG-TGA
D AGC-TAC-ACT
Answer
A, because If you just match the base pairs in the question to A they would match up
The DNA sequences will produce the following m-RNA: AGC-UAC-ACU is TCG-ATG-TGA. The correct option is A.
What is a DNA sequence?Finding the nucleic acid sequence, or the order of nucleotides in DNA, is the process of DNA sequencing. The four bases—adenine, guanine, cytosine, and thymine—are arranged in this way using any technique or technology.
Adaptor molecules that can recognize and bind to the codon, as well as the amino acid at a different place on their surface, are necessary for the translation of mRNA into protein.
These adaptors are made up of a collection of tiny RNA molecules called transfer RNAs (tRNAs), each of which is made up of roughly 80 nucleotides.
Therefore, the correct option is A. TCG-ATG-TGA is the sequence of m-RNA: AGC-UAC-ACU.

Which of the processes offers the GREATEST evolutionary advantage of sexual versus asexual reproduction?
А
meiosis
B В
mitosis
С
budding
D
binary fission
Answer:a
Explanation:
The process that offers the GREATEST evolutionary advantage of sexual versus asexual reproduction is MEIOSIS.
Meiosis is a type of cell division that is used by organisms of sexual reproduction to produce haploid (n) gamete cells.Meiosis produces new genetic variation in offspring due to:
the random separation of alleles in gametes when chromosomes separate crossing-over or recombination which is the interchange of genetic material between non-sister chromatidsgametes randomly fuse to produce a diploid (2n) organismIn conclusion, the process that offers the GREATEST evolutionary advantage of sexual versus asexual reproduction is MEIOSIS because it is capable of introducing new alleles and increasing genetic variation in a population.

Answer:
This was the only treatment options adopted for the Ebola in 1995 in the Democratic Republic of Congo. The assumption was that immune response is generated by the virus in the WBC of the infected individuals. These response produce antibodies.
A total if 8 patients were transfused with these blood contained antibodies, but one of these died, the remaining 7 patients survived.

how does matter move from the hydrosphere into the biosphere explain in your own words
Water mover form hydrosphere i.e river to biosphere i.e atmosphere by a process of evaporation.Thus, we can say that matter is move from hydrosphere to biosphere.
What is hydrosphere and biosphere?Hydrosphere:-
The hydrosphere is the collective mass of water which is found on under, or above the surface of earth. Although earth hydrosphere is 4 billions old. A planet's hydrosphere can be liquid, vapor or ice.
Biosphere:-
The region or area of surface where living organisms survive their life are called as biosphere. The biosphere is a narrow zone on the surface of the earth where soil, water, and air combine to survive life.
Evaporation:-
The process in which water or liquid converts into vapor is called as evaporation. In the case of water it starts vaporization at 100 degree C.
So, we can say that the conversion of matter from hydrosphere to biosphere is successfully achieved by evaporation.
Therefore, Water mover form hydrosphere i.e river to biosphere i.e atmosphere by a process of evaporation.Thus, we can say that matter is move from hydrosphere to biosphere.

Which of the following describes a second class lever
1. The fulcrum is located between the effort force and the load.
2. The effort force is located between the fulcrum and the load force.
3. The load force is located between the effort force and the fulcrum.
Answer:
I think the answer might be number 2
In the second class lever, the load is between the effort force and the fulcrum. The correct option is 3.
What is a fulcrum?The term can refer to the juncture or assistance on which a lever rotates, as well as the focal point of a critical activity or situation.
The term "fulcrum point" in zoology refers to an anatomical structure that serves as point of support.
The load in second-class levers lies among both the effort and the fulcrum. A wheelbarrow is a prominent example, where the effort moves a great distances to lift a substantial load, with the axle and wheel acting as the fulcrum.
In a second-class lever, the effort is distributed over a large area in order to raise the load a short distance.
Thus, the correct option is 3.
