Answer:

A. Explains how organisms change in response to the environment.

Explanation:

A scientific theory is an EXPLANATION of an aspect in the natural world. In other words, it just tells why something happens. Now it is not just a guess, it is well-supported by evidence and previous studies.

Now to knock out your other choices:

B. is wrong because:

A scientific theory does not predict. It can serve as a basis for a prediction, or what you call a hypothesis, but it does not predict an outcome.

C. is wrong because:

As mentioned earlier, a theory is WELL-SUPPORTED by evidence and previous research.

D. is wrong because:

A theory does not become a scientific law.

Biology Photosynthesis questions

Mazyrski [523]

I cannot do the part A task...... I can do the chart (: annddd the questions below..

Glucose: Glucose is a sugar made from sunlight, with the molecular formula C6H12O6.

chloryphll: The energy that is absorbed of the photon is transferred to an electron in a process called charge separation.

ATP: is a product of the first stage of photosynthesis, and it provides energy for the second stage. energy transfer; that is, ATP is able to store and transport chemical energy within cells.

Carbon dioxide: is involved in the production of refrigeration systems, welding systems, water treatment processes

chloroplast: contains the molecule chlorophyll, which absorbs sunlight for photosynthesis.

stomoata: control the flow of gases in and out of leaves.

Thylakoid: A thylakoid is a membrane-bound compartment inside chloroplasts and cyanobacteria. They are the site of the light-dependent reactions of photosynthesis. surrounded by a lunon.

stroma; involved in the Calvin Cycle – carbon fixation, reduction and regeneration. the stroma the supportive tissue of an epithelial organ, tumor, gonad, etc.

----------------------------------

Q2: oxygenic photosynthesis and anoxygenic photosynthesis.

Q3: The general principles of anoxygenic and oxygenic photosynthesis are very similar, but oxygenic photosynthesis is the most common and is seen in plants, algae and cyanobacteria.

Q4: water, light and carbon dioxide, while the products are oxygen and sugars.

Q5: carbon dioxide + electron donor + light energy ==> carbohydrate + oxidized electron donor + water

CO2 + 2H2A + photons ==> [CH2O] + 2A + H2O

*anatomy & physiology question*

Nimfa-mama [501]

Answer:

32 mm

Explanation:

The field of view is the total area visible through the microscope . The diameter of the field of view can be measured.

There is an inverse relationship between the magnification and the field diameter. As magnifications decreases, the field diameter increases by the same proportion, and as magnifications increases, the field diameter decreases by the same proportion.

The relationship between field diameter and magnification is:

magnification of A * field diameter of A = magnification of B * field diameter of B

120X * 8 mm = 30X * B

B = 120X / 30X * 8 mm

B = 32 mm = 32000 μm

The field diameter of 30X magnification is 32 mm (32000 μm)

Stella [2.4K]

Answer:

Polygenic inheritance

Explanation:

When multiple genes present at different loci on chromosomes regulate a single genetic trait, the trait is said to be polygenic and the inheritance is a polygenic inheritance. The phenotype of the individual is regulated by an allele of each gene in an additive manner. The sum total of phenotypic effects of each allele of all the genes determines the final phenotype of the individuals.

These traits not present in discrete contrasting pairs (such as tall and short) but exhibit quantitative variations. For example, skin color in humans is regulated by multiple genes and the phenotype of the individual ranges from very light to very dark with many intermediates in between.

In bacteria, translation of the mrna begins near the 5' end of the mrna molecule, when a(n).

AlladinOne [14]

When an mRNA attaches to the small ribosomal subunit in bacteria, translation of the mRNA starts close to the 5' end of the mRNA molecule.

As soon as mRNA is transcribed in bacteria, it is translated into protein. In contrast to eukaryotic cells, bacteria lack a distinct nucleus that divides DNA from ribosomes, removing a barrier to translation. Transcription and translation take place concurrently in these species. mRNA translation initiation in bacteria begins as soon as the messenger RNA (mRNA) molecule's 5' end has been created. Transcription and translation are interdependent processes that take place in these prokaryotic species. A short ribosomal-binding region that is located near the mRNA's 5' end helps bacterial mRNA bind to the small ribosomal subunit at the beginning stages of translation.
