Answers

Answer 1

Answer:

I think it is Chemical reactions produce glucose, ADP and NADPH

Explanation:

Answer 2

Photosynthesis is a chemical reaction that takes place to convert light energy. The photosynthetic light-dependent reaction forms glucose, ATP, and NADP⁺. Thus, option A is correct.

What is a light-dependent reaction?

A light-dependent reaction is a photosynthetic reaction that occurs in the presence of sunlight and produces chemical energy in the form of NADPH and ATP.

The products of the photosynthetic light-dependent reaction are used in light-independent reactions. In light-dependent, the photosystem gets excited and produces ATP from ETC, leading to reduction of NADP⁺ and photolysis of the water molecule.

Therefore, ADP and NADP+ are produced at the intermediary stage of the light-dependent reaction which makes them different from the light-independent reaction.

down.

There is also formation of two new nuclei of the daughter cells which are

Question 2:
In 1–2 sentences, explain what biome comprises most of Antarctica and why the continent is described as being part of this biome.

Answers

Answer:

question 1

Low-pressure areas are places where the atmosphere is relatively thin. Winds blow inward toward these areas. This causes air to rise, producing clouds and condensation. Low-pressure areas tend to be well-organized storms

question 2

Scientists that work in Antarctica mostly refer to the majority of the continent as being cold desert or polar desert. The difference between cold and polar desert is very technical, mainly dealing with mineral salt chemistry.

6 anaerobic

7 alcoholic and lactic acid.

8 Alcoholic fermentation is a biotechnological process accomplished by yeast, some kinds of bacteria, or a few other microorganisms to convert sugars into ethyl alcohol and carbon dioxide. ... Alcoholic fermentation begins with the breakdown of sugars by yeasts to form pyruvate molecules, which is also known as glycolysis.

9 In this reaction, a phosphate group (in red) is transferred from phosphocreatine to ADP to form ATP very rapidly, allowing muscle contraction to continue for about 10 seconds. When phosphocreatine is depleted, the muscles must turn to metabolism of fuel molecules to produce more ATP to power physical activity.

10 At this point, the runners' muscle cells are producing most of their ATP by lactic acid fermentation, which can usually supply enough ATP to last about 90 seconds.

12 After that, the body begins to break down other stored molecules, including fats, for energy. If photosynthesis is the process that "deposits" energy in a "savings account," then what is cellular respiration? It is the process that "withdraws" energy.

13 Cellular Respiration and Photosynthesis are almost opposite processes because photosynthesis removes carbon dioxide from the atmosphere while cellular respiration puts back carbon dioxide. Cellular respiration uses oxygen and has it's waste product of carbon dioxide (CO2).

[tex]BrainiacUser1357[/tex]

The model that shows the positions of the Sun, Moon, and Earth that have the greatest effect on ocean tides is the spring tide model.

What happen during the spring season?

During spring tides, the Sun, Moon, and Earth are in alignment, which causes the gravitational pull of the Sun and Moon to reinforce each other, leading to higher high tides and lower low tides.

Spring tides occur twice a month, during the new moon phase and the full moon phase.

In contrast, neap tides occur when the Sun, Moon, and Earth form a right angle, which causes the gravitational pull of the Sun and Moon to counteract each other.

This leads to lower high tides and higher low tides. Neap tides also occur twice a month, during the first and third quarter moon phases.

It's important to note that the positions of the Sun, Moon, and Earth aren't the only factors that affect ocean tides. Other factors, such as the shape of the coastline and the depth of the ocean floor, can also influence the height and timing of tides in a particular area.

The Venn diagram makes a comparison between categories. Intersection: Cell division/Asexual: diploid, somatic, mitosis, genetically identica/Sexual: haploid, gamete, meiosis, chromosomes separate , genetically different.

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

   

A Venn Diagram is represented as two or more circles with some degree of superposition between them. It is used to make comparisons expressing similitudes and differences between things.

Each circle represents a category -in this example, sexual and asexual reproduction-.

The superposed area is named intersection and shows things in common between the two categories.

We already know that sexual reproduction occurs by the process of meiosis, while asexual reproduction occurs by mitosis.

In superior organisms, there are two types of cells: Somatic cells and germ cells.

The somatic cells are diploid (2n), meaning that each cell has a pair of equal chromosomes. The somatic cells are all the body cells except for the sexual ones, and they reproduce by the process of mitosis.

In somatic cells, one of the sets of chromosomes is inherited from the maternal side, while the other homologous set of chromosomes is inherited from the paternal side. Hence, the number of chromosomes in these double sets of the somatic cells is diploid, 2n.

Mitosis is a process through which, from a diploid somatic cell (2n), two identical daughter diploid cells (2n) are produced.

First, occurs duplication of the cell content, and then the separation into two new cells happens.

Germ cells suffer mitosis and meiosis.  

Through meiosis, germ cells produce gametes, called sperm and egg cells, through the gametogenesis process.  

Gametes are haploid (n) with half the number of chromosomes that might be found in the somatic cells.  

During gamete formation, the pairs of homologous chromosomes separate after crossing over. Then, sister chromatids also separate. The result is the formation of four gametes.  

Each gamete has different information from the combination of homologous chromosomes belonging to the father and to the mother.

Gametes' destiny is to merge in the process of fecundation, during which a new diploid cell called zygote emerges through fertilization.

The zygote is a complete cell that suffers successive mitosis to form the new organism.

Answers

It is common for Sama-Banjou people to have an enlarged spleen, this is the result of environmental factors as a larger spleen helps them to dive better.

In most people, an enlarged spleen is not common and it is often related to specific conditions and diseases. Due to this, the percentage of people with an enlarged spleen is quite low.

Despite this, it has been found many Sama-Banjou people have an enlarged spleen and this is the result of environmental factors. Indeed, Sama-Banjou people have relied on diving to survive for centuries as they collect seashells from the seafloor.

This condition has led to bigger spleens, these bigger spleens increase the amount of oxygen while diving, and therefore, help them to dive for longer periods.

What is a nitrogen cycle?

The nitrogen cycle is the process by which nitrogen is converted into different chemical forms and moves between the biosphere, atmosphere, and geosphere. The stages of the nitrogen cycle, in order, are:

Nitrogen fixation: Nitrogen gas in the atmosphere is converted into a usable form, such as ammonia or nitrite, by nitrogen-fixing bacteria.

Nitrification: Ammonia or nitrite is converted into nitrate by nitrifying bacteria.

Assimilation: Nitrate is taken up by plants and converted into organic nitrogen compounds, such as proteins and nucleic acids, through the process of assimilation.

Ammonification: Organic nitrogen compounds are broken down by decomposers, such as bacteria and fungi, into ammonia or amino acids.

Denitrification: Ammonia or nitrite is converted back into nitrogen gas by denitrifying bacteria, completing the cycle.

What are anaerobic respirations?

All living cells undergo respiration, a chemical activity that releases energy from glucose. Without oxygen, anaerobic respiration occurs and produces less energy but does it more quickly. Fermentation refers to anaerobic respiration in microorganisms.

When you work out vigorously, your muscles engage in anaerobic respiration. Compared to aerobic respiration, less energy is released because glucose is not completely broken down.

During intense activity, lactic acid accumulates in the muscles. Later, the lactic acid must be oxidized to produce carbon dioxide and water.

Therefore, the correct option is D) Anaerobic respiration.
