Which of the following is true about the Calvin cycle?

Both ATP and NADPH are needed to make sugars.
Light energy is converted to chemical energy.
Answers
Answer:
1. ATP - decrease
2.NADPH - decrease
3. sugars - decrease
And True- Both ATP and NADPH are needed to make sugars.
Explanation:
Photosynthesis is a form of biosynthesis that produces glucose from the reactants; it uses energy from sunlight, along with carbon dioxide and water. It happens in the chloroplast in two phases; the light-dependent and dark reactions. In the light reaction, solar energy stimulates photosystems, formed from pigments like chlorophylls.
Chlorophyll forms photosystems of proteins known as complex proteins (PS I & PSII). PS II absorbs and moves the reaction center with light energy.
H+, and oxygen, are formed from a water molecule as it's broken apart. From photosystem II, electrons are transferred to photosystem I. ATP is synthesized from ADP along with inorganic phosphate. To form NADPHH, H+ is added to NADPIf PS II no longer works, there will be less ATP, NADPH, (both used later on) and no sugars produced.
In the dark reaction, products of the light reaction are used to make sugars. Here, in the Calvin cycle, the enzyme, RuBisCO, catalyzes the fixation of CO2 with Ribulose 1,5-bisphosphate (RuBP).

A sample of Carbon-14 originally contained 100 g. After three half-lives have
passed, how much Carbon-14 is left?
Answers
Answer:
After 3 half lives 12.5 g of C-14 left
Explanation:
Given data:
Mass of C-14 = 100 g
After 3 half lives mass left = ?
Solution:
At time zero = 100 g
At first half life = 100 g/2 = 50 g
At second half life = 50 g/ 2 = 25 g
At third half life = 25 g/2 = 12.5 g
Thus, after 3 half lives 12.5 g of C-14 left.

Answers
Answer:
ribonucleic acid, a nucleic acid present in all living cells. Its principal role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins, although in some viruses RNA rather than DNA carries the genetic information.
Explanatioim smart now give brainliest plz
Answer:
Ribose, found in RNA, is a "normal" sugar, with one oxygen atom attached to each carbon atom. Deoxyribose, found in DNA, is a modified sugar, lacking one oxygen atom (hence the name "deoxy"). In ribose, carbon atom #2 carries one hydroxyl group (colored red).
RNA is a ribonucleic acid, a nucleic acid present in all living cells. Its principal role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins, although in some viruses RNA rather than DNA carries the genetic information.DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule.Explanation:
Sea turtles spend most of their lives at sea feeding on jellyfish. When it is time to lay their eggs, mature females come ashore. They dig nests in the sand along the coast, lay their eggs, and then return to the sea. The data below show the changing sea levels since the late 1800s.
If the current trend shown in the graph continues, what prediction is most likely regarding the future of sea turtles?
a. Fewer jellyfish will wash up on the beach for the turtles to feed on.
b. More predators will be found on the beaches to threaten the baby turtles.
c. The baby turtles will have to travel farther to reach the ocean.
d. The beaches on which turtles currently lay their eggs may go underwater.
Answers
Answer:
d. The beaches on which turtles currently lay their eggs may go underwater.
Explanation:
According to the graph, the beaches on which turtles currently lay their eggs may go underwater due to increase sea level with the passage of time. In the graph, we can see that sea level increases from 1880 to 2014 and the main reason for this increase is the climate change. Due to global warming the water present on the glacier starts melting and thus increase in sea level occurs so the beaches on which turtles currently lay their eggs may go underwater.

d. To copy original DNA strands into complimentary strands
Answers
Answer:
D
Explanation:
To copy original DNA strands into complementary strands
The option (D) is correct. To copy original DNA strands into complimentary strands.
What are complementary strands of DNA?Complementary DNA (cDNA) is a DNA copy of a messenger RNA (mRNA) molecule produced by reverse transcriptase, a DNA polymerase that can use either DNA or RNA as a template.
Moreover, the complementary strand for DNA must follow the base pairing and polarity rules. Pairing means that A=T and G=C. Polarity means that the strands have to run in opposite directions. First write the correct base pairing below the original sequence and label the 5' and 3' ends.
Therefore, the upper strand of DNA is the "mRNA-like" strand. The lower strand is the strand that is complementary to the mRNA.

A powerful windstorm moves through a densely populated white oak forest. The oaks in this forest have either smooth or rough bark. The storm randomly knocks down 50% of the white oak trees. The remaining oaks grow and produce seeds that germinate and fill in spaces in the forest. All of the new oaks have smooth bark. Which of these processes is described in this example?
Answers
Answer:
Secondary succession.
Explanation:
These processes is known as Secondary succession because disturbance occurs in the environment due to powerful windstorm which eliminates rough bark oak tree while no damaged happen to the smooth bark oak tree. So the next time the plants grow in the place of rough bark oak tree because rough bark oak tree can't withstand in that type of environmental condition and all population is available of smooth bark oak tree due to their survival mechanism.

the number of consumer can never exceed the number of producer in nature why
Answers
Answer:
The number of consumer can never exceed the number of producer in nature because there is a limited amount of producer in the nature so the consumers is the one who eats a producer !
When the number of consumers increases, producers disappear due to overconsumption and consumers disappear due to lack of food and the ecosystem is destroyed. Therefore, in nature the number of consumers can never exceed the number of producers.
What are Producers and Consumers?Producers are plants that make their own food, the energy they need to grow, reproduce, and survive. They are making their own food which makes them special. These are the only living things on Earth that can make their own source of food energy with the help of sunlight, water and air.
Consumers make up the upper trophic level. Unlike producers, they cannot make their own food. They obtain their food by eating plants or other animals, while some eat both.
Scientists distinguish between several types of consumers. Primary consumers form the second trophic level.
Thus, when the number of consumers increases, producers disappear due to overconsumption and consumers disappear due to lack of food and the ecosystem is destroyed. Therefore, in nature the number of consumers can never exceed the number of producers.

What are some of the ways that parasites have adapted to transmission between hosts and resisting the host’s attempts to get rid of the parasite? How do these particular developments help the parasite?
Answers
Organisms depend on other species for resources such as nutrients. Parasites live in or on another organism, which is called the host. The parasite takes what it needs from the host but the host receives nothing in return and often suffers as a result. An example of parasitism is the relationship between fleas and dogs. Fleas live on dogs and feed on their blood. The dog receives no benefit but the fleas are provided with food and a habitat. Fleas attach themselves to hairs and can spread from one host to another by jumping huge distances.

In the case of this plant, whose phenotype is tall and green —both dominant characteristics— and considered pure because both alleles are dominant, the genotype is TTGG.
In the case of a hybrid, the phenotype would be the same but the genotype would be TtGg. A recessive phenotype would be ttgg.Which is an example of codominance
