6. True. In this photo C is the both a transformation of chemical energy to heat and mechanical. Mechanical that runs the factory in the photo, and Heat energy that rises up in the atmosphere to join the other carbon molecules in the air.

7. True. The arrow letter A is the transfer of solar power from the sun, to a chemical reaction to produce food for the plant, which is called photosynthesis. The leaves in the plant has chlorophyll that absorbs light energy and transforms it to food.

8. The answer would be letter C and F. C because It is during the burning of the fossil fuels that the carbon dioxide is release into the atmosphere. When burning the fossil fuels the carbon that was inside the fossils is released. This also happens with diesel and other forms of natural gas.

 While, F is because plant respiration releases some of the carbon remains of the photosynthesis. While plants do absorb carbon dioxide, part of their end product also includes reformed carbon dioxide. Most of the other processes in the phot uses carbon or absorbs carbon dioxide to aid their sustenance.

9. A carbon cycle for living things would be A or B to F wherein the plants absorb carbon dioxide to aid their production of food, and then releasing carbon dioxide again as a by product of their food production. This also happen to aquatic plants.

An example of a non-living carbon cycle would be, D or E to C. This would be the absorption of the carbon on our sea waters or to our soil, this then gets trapped in there until it is release like through the forms of fossil fuel burning.

10. The law of conservation of mass and energy states that matter can neither be created nor destroyed, this is very much evident in the carbon cycle. Because the carbon from the light energy from the sun, or in our atmosphere, ends up back to our atmosphere just to continue its cycle. The fact that the carbon cycle is a cycle not just a linear equation proves that energy can neither be created nor destroyed.

Periaqueductal gray neurons send descending axons into various regions of the medulla releasing serotonin.
Evgesh-ka [11]

Answer:

True

Explanation:

Periaqueductal gray matter is found in the middle portion of brain.  When this grey matter is stimulated it activates neurons that releases enkephalin. Enkephalin further direct the stimulation to the raphe nuclei  with in the brain stem that releases serotonin. In this process, the ascending and descending axons are released  from  

a) subcortical nuclei

b) spinal trigeminal nuclei  

c) the spinal cord

Hence, the given statement is true

What happens in crossing over? Why is it important for sexually reproducing organisms, and what is one of the consequences of er
BaLLatris [955]

Answer:

Crossing over increases the genetic variation  

Errors in crossover formation result in chromosomal rearrangements (duplications and deletions) and may also cause chromosome nondisjunction

Explanation:

Crossing over, also known as recombination, refers to the exchange of genetic material (DNA) between non-sister chromatids of homologous chromosomes during meiosis. Crossing over increases the genetic variation of the resulting gametes, allowing different genetic combinations to be passed from parents to offspring. Unequal crossing over is a type of error associated with chromosomal duplication and/or deletion events. Unequal crossing over occurs when homologous sequences are not paired precisely. Moreover, errors in crossing over may also cause chromosome nondisjunction, thereby leading to aneuploidies.

1. · Explain the origin of coal and name its various varieties.
scZoUnD [109]

Answer:

Coal gas is a flammable gaseous fuel made from coal and supplied to the user via a piped distribution system.It is produced when coal is heated strongly in the absence of air. ... Facilities where the gas was produced were often known as a manufactured gas plant (MGP) or a gasworks.

Coal tar is a thick dark liquid which is a by-product of the production of coke and coal gas from coal. It has both medical and industrial uses. Medicinally it is a topical medication applied to skin to treat psoriasis and seborrheic dermatitis (dandruff). It may be used in combination with ultraviolet light therapy.

: a bituminous coal suitable for making into coke.

To map genes of a bacterial strain, conjugation must be interrupted at given times. Suppose you have Hfr cells of genotype a+b+c
OLEGan [10]

Answer:

The answer is not in any of the options and is the following:

to eliminate any remaining Hfr cells.

Explanation:

In a medium that has a streptomycin antibiotic it is used to kill Hfr donor cells after the conjugation is interrupted. This is entirely due to the streptomycin sensitivity allele (str-s) which are found in Hfr strains. The presence of the streptomycin resistance allele, located in the receptor, is used for the specific destruction of Hfr donor cells after conjugation occurs.

A healthy way to gain weight would be to simply add more calories to your diet. Group of answer choices
marissa [1.9K]

<u>Answer</u>:

A healthy way to gain weight would be to simply add more calories to your diet is a <u>TRUE</u> statement.

<u>Explanation</u>:

The number of "calories" that an individual consumes and burns daily plays an important role in determining his/her weight. A person who consumes more calories than he burns daily could become overweight whereas if a person is consuming fewer calories than what he burns could cause him to lose weight.

The best way to gain weight is to "add more calories" to one's diet while also keeping in mind the number of calories being burnt daily. The newly added calories should sum up greater than the total calories burnt regularly.

Hence, the statement about adding calories in the diet to gain weight is true.
