Answer:

The sequence on the complementary strand is B.TAACGGGTAC.

Explanation:

In DNA's molecule two complementary DNA strands interact forming a double helix by base pairing. This base pairing follows rules called "Watson-Crick base pairing". In this rule a specific pyrimidine pairs only with a specific purine, Adenine (A) with Thymine (T) and Cytosine (C) with Guanine (G).

If we Know the base sequence of one strand of DNA, we can deduce the base sequence of the other.

The noncyclic pathway is a FLOW of electrons from water, to photosystem II, to PHOTOSYSTEM I to NADPH. Energy is released as ELECTRONS move through the first electron transfer chain. This energy pumps HYDROGEN IONS into the thylakoid compartment, and then they power the formation of ATP as they flow back out. Sunlight provides the energy needed to keep this cycle going.

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

Luminous energy is trapped by chlorophyll in Photosystem II.
When the pigment molecules absorb light, electrons provided by water molecules get in a higher energy level.
The excited electrons go through the electron transport chain from Photosystem II to a less energetic level in photosystem I.
When the excited electrons leave photosystem II, they are replaced by new electrons extracted from the water molecules.
Luminous energy absorbed move the electrons from the photosystem I to another electron acceptor, from where they get transported again and used to produce NADPH molecules.
When electrons leave Photosystem I, they are replaced by new electrons coming from photosystem II.
When the water molecule breaks down, hydrogen ions remain in the thylakoid lumen, from where they are pumped to the stroma by the ATP synthase.
The released energy is used to produce ATP molecules.
Hydrogen ions go back from the stroma to the thylakoid compartment.

The final products are oxygen, ATP, and NADPH.

Gas giants have rings and satellites. True or False

Soloha48 [4]

That statement is True
Gas giants refer to the large planets the made up from large composition of gas.
These planets are located significantly further from the sun compared to another planet, which makes them have more debris left over from their formation, which will turn either into rings or moons (satellites) that surround these planets.

What type of rock does direct pressure make

natka813 [3]

I think it is called the METAMORPHIC ROCK.

It formed not only when the pressure changes but also with the heat.

Good luck :)

Why is breaking and rearranging bonds in the process of photosynthesis and cellular respiration important? WILL GIVE BRAINLIEST

____ [38]

Answer:

Photosynthesis

All organisms in the plant kingdom are autotrophs/producers and therefore carry out photosynthesis. Photosynthesis occurs in the chloroplast (figure 1) of plant cells which are concentrated predominantly in the leaves. The chloroplasts contain the green pigment chlorophyll, giving leaves their green color, and is responsible for capturing light energy to power photosynthesis.

Picture

Figure 1

All living things need a few basic things to survive, we learned these things as the four basic needs of living things. Plants are no exception to this and require space, gases, food, and water like all other living organisms.

The two basic needs, water and gas are especially important for a plant to carry out photosynthesis. The water and gas makeup two of the three reactants of photosynthesis. The needed water (H2O) is absorbed from underground into the roots of the plant and is then transported to each cell by the vascular tissue xylem.

Picture

Figure 2 https://upload.wikimedia.org/wikipedia/commons/d/db/ Photosynthesis.gif

Plants cannot carry out photosynthesis without carbon dioxide (CO2), the gas animals exhale. Plants take in CO2 and release O2 (the opposite of animals) by the process of transpiration (respiration in animals).

Although plants do not have lungs or lung-like structures, they do have small pores on the underside of their leaves that regulate transpiration. These pores are called stoma or stomata and allow CO2 and O2 to enter and exit the plant leaves. Each stoma is surrounded by two guard cells that open and close the stoma. Stomata remain open when the plant is in need of CO2, during photosynthesis, and closed during times of photosynthetic inactivity. You will be conducting a lab during which you will test when stomata tend to be open vs when they tend to be closed.

In addition to CO2 and H2O, plants must also have sunlight or light energy. As mentioned above, the light energy absorbed by the chlorophyll powers the process of photosynthesis. Sunlight is responsible for breaking the molecular bonds of the CO2 and H2O and then rearranging the atoms into the products of photosynthesis, glucose (C6H12O6) and oxygen (O2). Through photosynthesis, light energy is converted into stored energy, the glucose (food).

To summarize: Energy from the sun is converted into stored chemical energy or food called glucose in the plant cell by the process of photosynthesis. The green pigment- chlorophyll- is located in the chloroplast and captures the sunlight. The energy from the sun is then used to change the carbon dioxide and water into the sugar glucose and oxygen. Glucose is a sugar that is stored energy for later use.
