Answer:
Answer is as follows
Explanation:
Similarities:1. They are similar as energy is the main source in these both reactions.
Differences:1. In light reactions energy is taken from sunlight while in dark reactions the created energy in light reactions is used.
Final answer:
The light reactions and dark reactions of photosynthesis are similar in that they both contribute to the process of carbohydrate synthesis in plants. They differ in that light reactions need sunlight to produce ATP and NADPH, while dark reactions do not, using these molecules to fix CO₂ into carbohydrates.
Explanation:
One way the light reactions and dark reactions (Calvin cycle) of photosynthesis are similar is that both processes are crucial for the synthesis of carbohydrates in plants. Both sets of reactions are part of the overall process of photosynthesis, which is how plants convert light energy into chemical energy stored in glucose. A key difference between the two is that light reactions require sunlight to produce ATP and NADPH, while dark reactions do not require light and instead use the ATP and NADPH produced by the light reactions to fix carbon dioxide into carbohydrates like glucose. The light reactions occur in the thylakoid membranes of the chloroplasts, whereas the Calvin cycle occurs in the stroma of the chloroplasts.

6.C
7.A
Explanation:
B. Bacteria can exchange genes for resistance to antibiotics in this way. Bacteria can take up genetic material from other bacteria or the environment during a process called transformation. This is relevant to humans because we can modify bacterial ADN with a gene of our choice and due to this transformation process, other bacteria can take up this modified ADN. B. All animals are heterotrophs. This means we can not produce food for ourselves inside our bodies. Instead, we have to consume it from another source in nature, for example, animal meat, fruits or vegetables.B. Species have specific adaptations to their local environment. In Darwin's finches for example, he found out that very similar birds had different peaks and head shape. He wanted to find out why they were so different yet so similar. He found out that depending on the food source available on the environment, the birds had a particular shape of peaks and head so they can feed properly.This adaptations and changes allow the birds to survive in a particular local environment.C. Mutualistic relationship. A mutualistic relationship is a biological interaction in which both organisms benefit. In this particular case, the Dinoflagellates provides energy to the coral and the coral protects the dinoflagellates against predators. This question is the same as the 4th one.C. recessive. The recessive hypothesis exposes that viruses were intracellular parasites that lost the required genes for replication and maintenance. So, they depend on host cells and their replication genes and processes to live.A. Analogous structure. An analogous structure is a trait that has a similar role, but whose origin is different. In this particular case, the insects, birds, and bats have different origins and ancestors but they all evolve wings to fly.Question 7 (5 points)

What statement correctly compares chemical reactions with nuclear reactions?
Chemical reactions involve the transfer or sharing of electrons without changing the nuclei, while nuclear reactions involve changes in the nucleus, leading to different elements and the release or absorption of a massive amount of energy.
Explanation:Chemical reactions and nuclear reactions differ fundamentally in the processes and changes that occur at the atomic level. In a chemical reaction, electrons are transferred or shared between atoms, leading to the formation and breaking of chemical bonds. However, during these reactions, the nuclei of the atoms remain unchanged, and the number of atoms of each element is conserved, indicating adherence to the law of conservation of mass. On the other hand, a nuclear reaction involves changes to the nuclei themselves, which can result in the transformation of elements and a notable release of energy.
Nuclear reactions often involve the rearrangement of nucleons (protons and neutrons) within the nucleus, leading to the emission or absorption of particles, such as alpha (α) particles, beta (β) particles, or gamma (γ) rays. These reactions are accompanied by enormous energy changes, far exceeding those of chemical reactions. Nuclear reactions can lead to a change in mass that, according to Einstein's equation E=mc², corresponds to a significant release or absorption of energy. Unlike the case of chemical reactions, in nuclear reactions the laws of conservation of mass and energy are not individually valid but are combined into the law of conservation of mass-energy.
The energy changes in nuclear reactions can be observed in processes such as fission, where heavy nuclei split apart releasing energy, or fusion, where light nuclei combine to form a heavier nucleus, also releasing energy. The amount of energy involved in nuclear reactions is orders of magnitude greater than for chemical reactions, illustrating the major difference in energy scales between the two types of reactions.

The DNA double helix is antiparallel. This means that the two strands
A. are parallel and are identical to each other.
B. cross over each other many times.
C. are parallel and run in opposite directions.
D. are parallel and are the mirror images of each other.
C. are parallel and run in opposite directions.
Explanation – Deoxyribonucleic acid (DNA) is double stranded molecule present inside the nucleus of the cell and has double helical symmetry. The two strands run or proceeds antiparallel to each other which means that one strand proceeds from 5' to 3' direction while the other strand proceeds from 3' to 5' direction.
It so happens because the nitrogenous base from one strand binds to its complimentary base pair of the other strand. Hydrogen bond is the bond that connects nitrogenous bases of two strands.

why is it impossible for exponential growth to continue forever?
Answer: If the population of certain organism starts to grow exponentially, will reach a point in which there are to many organisms, and the food is limited, so the organisms start to compete with each other for food. So the population "regulates" itself, which makes the exponential growth impossible to continue forever.

Identify the products of cellular respiration and photosynthesis
Answer:
Cellular respiration:
[tex] C _ 6 H _ { 1 2 } O _ 6 \implies 6 C O _ 2 + 6 H _ 2 O + 3 8 A T P [/tex]
Photosynthesis:
[tex]6CO_2+12H_2O \implies C_6H_{12}O_6 +6O_2+6H_2O[/tex]
Explanation:
The process of breaking down the sugar into a form of usable energy by the cell is called cellular respiration.
It can be shown by an equation as:
[tex] C _ 6 H _ { 1 2 } O _ 6 \implies 6 C O _ 2 + 6 H _ 2 O + 3 8 A T P [/tex]
So the product here includes ATP which is the energy along with carbon dioxide and water.
While photosynthesis is the process where sunlight is used to convert the carbon dioxide into sugars to be used as energy.
[tex]6CO_2+12H_2O \implies C_6H_{12}O_6 +6O_2+6H_2O[/tex]
Here the products are sugars, oxygen and water.
