"where does the energy for the calvin cycle come from?"

Answers

The nucleus is where energy come from 

Final answer:

The Calvin cycle uses ATP and NADPH, which contain energy from sunlight, to turn carbon dioxide into carbohydrates, such as glucose, for long-term energy storage.

Explanation:

The energy for the Calvin cycle is derived primarily from ATP and NADPH, which are compounds rich in chemical energy. These molecules are produced during the light-dependent reactions of photosynthesis.

The ATP and NADPH, carrying energy captured from sunlight, are utilized by the Calvin cycle to convert carbon dioxide into carbohydrate molecules, such as glucose, which serve as long-term energy storage for the cell. Specifically, the Calvin cycle harnesses the energy in the form of 6 ATP and 6 NADPH to produce Glyceraldehyde-3-phosphate (GA3P) molecules that will eventually form the backbone of carbon atoms for carbohydrates, primarily glucose. Thus, the Calvin cycle effectively converts the short-lived energy stored in ATP and NADPH into a more stable form of energy in carbohydrates, a process essential for life on Earth.

What is the result of meiosis II?

two diploid daughter cells
four haploid daughter cells
two haploid daughter cells
four diploid daughter cells

Answers

I think two haploid daughter cells

Answer: Option B

Explanation:

In some species there is a very small interphase, or interkinesis before the cell enters in the the process of meiosis II.

The two daughter cells that are produced after meiosis I go though the process of meiosis II. During the process of meiosis II the two sister chromatids which lies in daughter cells separate, resulting in formation of four haploid daughter cells. This process is similar to mitosis.

Based on the table, which domains contain only one cell type? Fungi and Eukarya Bacteria and Archaea Eukarya and Fungi Plantae and Bacteria

Answers

The right answer is Bacteria and Archaea.

A prokaryote is a unicellular organism (bacterium, cyanophyceae) that does not have a nucleus. The DNA is circular, usually unique and grouped in a nucleoid. This region contains the genetic material, but is not separated from the rest of the cell. This is precisely what separates the prokaryote from the eukaryote.


Archaea are prokaryotic unicellular microorganisms. Archaea, which often look like bacteria, have long been regarded as specific extremophile bacteria, until phylogenetic research on prokaryotes, begun in 19652, culminated in the publication in 1977 of a phylogenetic tree based on the sequences of the ribosomal RNA genes of the organisms studied, a tree in which the prokaryotes were split into two distinct domains, that of the bacteria and that of the archaea.

Final answer:

The domains that contain only one cell type are Bacteria and Archaea as all organisms within these domains are unicellular.

Explanation:

In the context of biological classification, cell type is one way to categorize living organisms. The question refers to 'domains', one of the highest taxonomic ranks in this system. In terms of cell type, all organisms in the domains Bacteria and Archaea are unicellular, meaning they only have one cell type. However, other domains like Eukarya include both unicellular organisms (like some fungi and protists) and multicellular organisms (including animals, plants, and most fungi).

Answers

Final answer:

Osteons, or Haversian systems in compact bone, resemble the concentric growth rings in a tree trunk. They provide structural strength and help in the body's mineral balance.

Explanation:

The statement that the structural unit of compact bone (osteon) resembles the growth rings of a tree trunk is true. Osteons, or Haversian systems, are cylindrical structures that consist of concentric rings, called lamellae, of compact bone tissue that encircle a central canal (the Haversian canal).

Immunity how does our immune system protect us from disease pogil answers

Answers

Our immune system protects us from foreign and damaging organisms through our antigens. Once a pathogen (damaging cells/harmful) is detected within the body, the immune system deploys white blood cells to defend the host and eliminate the threat. The Immune System acts as our body’s security system.

Final answer:

The immune system is a complex network of cells, tissues, and organs that work together to protect the body from harmful pathogens. It includes key components such as white blood cells, antibodies, and the complement system.

Explanation:

The immune system is a complex network of cells, tissues, and organs that work together to protect the body from harmful pathogens, such as bacteria, viruses, and parasites. its components are -

White blood cells: These cells are the main players in the immune system. They include neutrophils, macrophages, and lymphocytes.Antibodies: Antibodies are proteins produced by B cells and play a critical role in identifying and neutralizing harmful pathogens.Complement system: The complement system is a group of proteins that work together to enhance the immune response.

The immune system has two main phases: the innate immune response and the adaptive immune response. The innate immune response is the first line of defense and provides immediate, nonspecific protection. It includes physical barriers (e.g., skin), chemical barriers (e.g., stomach acid), and certain white blood cells. The adaptive immune response is specific to a particular pathogen and develops over time. It involves the production of antibodies and memory cells that provide long-term immunity. Our immune system is crucial for protecting us from diseases. It employs a network of cells, tissues, and organs to identify and eliminate harmful pathogens. Understanding how our immune system works can help us make informed choices to stay healthy.

I chose this because it's the only one not explained about these types of rocks and they aren't used a lot. (this just my opinion so you don't have say im right).

Answer:

D. They are very productive agriculturally.

Explanation:

Laterite soils are of rusty red color. Their red appearance is because of the fact that they have very high content of iron and iron oxide. They are formed in wet tropics naturally. They are not at all suitable for agriculture because they are highly acidic in nature. Not only this but also, they have very low water retention capacity. These two properties make them unsuitable for cultivation.

Stages of mitosis and what happens in each stage.

Answers

There are 4 stages in Mitosis...
Prophase:
It is the first phase in which the chromatin coil to become chromatids, and those chromatids pair up and the nuclear membrane surrounding them dissolves. The centrioles move to each end (pole) of the cell.
Metaphase:
Where the paired chromatids align in the centre of the cell and spindle fibres attach to them at the centromere. 
Anaphase:
The centrioles act as anchors, tearing the paired chromatids away from each other using the spindle fibres. Each paired chromatid moves to either (the opposite) end of the cell.
Telophase:
Where the chromatids elongate to form chromatin, and a nuclear membrane begins to form around the chromatin at each end of the cell. Cytokinesis occurs in this stage as the cell separates into two daughter cells. In animal cells, there is cleavage as the two cells are starting to separate. In plant cells, a plate begins to form.
