Which of the following is the source of the carbon found in glucose molecules?

Answers

Answer 1

Answer:

Carbon dioxide

Explanation:

When the plant makes the glucose molecule, it gets the carbon and oxygen atoms it needs from carbon dioxide, which it takes from the air. Carbon dioxide doesn't have any hydrogen in it, though, so the plant must use another source for hydrogen. The source that it uses is water

Mitosis is the process by which a parent cell becomes two identical daughter cells. So, the correct option is (D)

What is mitosis ?

Mitosis is the process in which cell duplication, or reproduction takes place. Wherein one parent cell gives rise to two genetically identical daughter cells. Mitosis is the duplication and distribution of chromosomes which carries the genetic information.

It is an important process in single celled eukaryotes as it is the mode of asexual reproduction. The main function of Mitosis is to produce more cells.

Life starts with single cell in multicellular organism which is formed from two gametes. Mitosis takes place one cell is divided into two cells as this single celled multicellular organism only carries genetic information in the form of DNA but not enough cells. These two cells further divide mitotically into four cells, then into 8 , then 16 and then 32.

It is essential to life because it give rise to new cells for growth and replacement of dead cells. It may take few minutes or some hours, depending on the type of cells. It depends on time, temperature and chemicals.

Thus, mitosis is the process by which a parent cell becomes two identical daughter cells. So, the correct option is (D).

To test a new drug that has the potential of curing people of the common
cold a company asked human volunteers who were coughing and sneezing
to participate in a clinical study. The objective of the experiment was to test
whether the new drug could cure the volunteers in the experimental group of

O A To prove that the common cold cannot be cured
B. To provide the volunteers in the study with something to drink
O C. To help researchers conclude that results are related to the new
drug and not to the orange juice
O D. To confuse anyone who is trying to steal their new drug and sell it

Answer: C

Explanation: A good experiment does everything it can to eliminate confounding, or the influence of external sources on the data being measured. Orange juice could be a factor that plays a role in curing the symptoms, so provide a group with and without orange juice gives you the ability to show that the influence of orange juices didn’t have an effect on the cold, or did, but it gives you a baseline to show the effects of the medicine with and without orange juices.

Telophase is regarded as the final stage of mitosis before cytokinesis takes

down.

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

separated by the newly formed nuclear membrane which is evident in the

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.

The protein that carries oxygen in our blood is known as hemoglobin.

Iron is a component of hemoglobin, which enables it to absorb oxygen from the air we breathe and transport it throughout the body.

What is Hemoglobin?

The iron-containing oxygen-transporting metalloprotein known as hemoglobin, often known by the abbreviations Hb or Hgb, is found in the red blood cells of almost all vertebrates as well as some invertebrate organs. The oxygen from the respiratory organs is transported to the rest of the body by hemoglobin in the blood.

The normal ranges for haemoglobin are different for males and females, and they also vary depending on the ethnicity of the population. Additionally, age is a factor, particularly for women.

When you have anemia, your body doesn't produce enough healthy red blood cells to supply your tissues with enough oxygen. Anemia, commonly known as low hemoglobin, can make you feel exhausted and frail.

The microscope can be used to demonstrate the segregation of chromosomes during cell division. The law of segregation of characters is a Mendel's Law.

Each allele or gene variant is located at a specific chromosome location known as a gene locus.

The Law of Segregation indicates how one offspring receives one allele from each parent for each locus in a diploid organism.

The development of microscopy confirmed the idea that offspring receives one allele (which is located at a specific chromosome) from each parent for each gene locus.

Construct a Venn diagram that compares and contrasts sexual and asexual reproduction.

Answers

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.
