Photosynthesis-

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's metabolic activities. Photosynthesis occurs in the chloroplast of a plant, which contains chlorophyll. In order for photosynthesis to take place, it needs to have water and carbon dioxide, the two very important raw materials necessary for this process. In the presence of carbon dioxide, such cells are able to convert this solar energy into energy-rich organic molecules, such as this energy-rich molecule known as glucose. Oxygen the by product of photosynthesis is inhaled by heterotrophs which aids in cellular respiration and other internal processes and then exhales carbon dioxide. ... In like manner, carbon dioxide passes from blood to the alveoli and exhaled after

Answers

Answer:This is an example of asexual reproduction.

Explanation:

Reproduction is defined as the ability of living organisms to produce offspring, that is, new individuals of their type. Living organisms have developed many methods of reproducing. These can be either ASEXUAL or SEXUAL.

Asexual reproduction: In asexual reproduction, an individual produces an offspring by itself, that is, only one parent is present. This type of reproduction is common among flowering plants. Examples of asexual reproduction includes:

--> Fission

--> Budding

--> Spore formation

--> Fragmentation and

--> Vegetative propagation.

The sweet potato vine is reproduced by an asexual means known as vegetative propagation. Here, a new plant grows from any portion of an old one other than the seeds. When stem cutting are taken from the vine, new storage roots are formed within few days.

Brady took a cutting from a sweet potato vine in his family garden and placed the vine in a small vase filled with water. After about a week, tiny roots had begun to grow which is an example of - Asexual reproduction.

Asexual reproductionis a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes.Examples of asexual reproduction include:   Fission  Budding  Spore formation  Fragmentation and  Vegetative propagation.In the given scenario sweet potato is cultivated by vegetative propagation.Brady takes stem cuttings from the vines, which then root and form new storage roots.Sweet potatoes are relatively easy to propagate by rooting vine cuttings directly in the ground or in a well-drained rooting media

What epigenetic marker changes cause chromatin to open up?

Answers

Answer Several lifestyle factors have been identified that might modify epigenetic patterns, such as diet, obesity, physical activity, tobacco smoking, alcohol consumption, environmental pollutants, psychological stress, and working on night shifts.:changes to the histone tails act indirectly on the DNA. For example, lysine acetylation may create a binding site for chromatin-modifying enzymes (or transcription machinery as well). This chromatin remodeler can then cause changes to the state of the chromatin. hope this helps ❤️❤️❤️

Explanation:

The changes with respect to the epigenetic marker should result to the chromatin at the time of opening up because When transcription factors could access the DNA binding sites.

Reasons of chromatin:

It is the material that comprises of the chromosome that involved the DNA and protein. The major protein is called as the histones. It should be acted as the packaging elements with respect to the DNA.

how does the coconut plant adapt in goa​

Answers

Goa's climate is tropical, hot all year round, with a long and sunny season, which runs roughly from mid-October to mid-May, and a rainy season due to the south-west monsoon, more or less from late May to early or mid-October, and characterized by stuffy weather, cloud cover and frequent rains, which occur almost daily .

The coconut seed is especially well adapted to increasing its range by the method of ocean dispersal. The seed floats when its outer layers dry out. The buoyant coconuts drift on ocean currents and end up on tropical beaches where they germinate and take root.

Coconut tree grows only in the tropical climate. This plant live on the sandy soil, requires a lot of sunlight and regular rainfalls. Coconut tree does not tolerate low temperatures and low percent of humidity.

Answers

Answer:

A phosphate backbone is the portion of the DNA double helix that provides structural support to the molecule. DNA consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are held together by bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.

Answers

Answer:

The ethics of artificially inserting traits in animals has been in the practice for years in the form of selective breeding, but should scientists really be editing DNA to the extent they are today? I don't believe they should. Life itself should construct itself without us interfering. Making a brand new plant just because it looks nice doesn't account for many factors, including the fact that it could be harmful to nearby plants if pollinated. In addition, generic engineering costs quite a lot of money, which should be used on other more cost effective methods, such as improving agriculture rather than creating a whole new plant that could harm entire crops. Genetic engineering isn't a necessity and humans should not play God with plant and animal life.

Design your own scenario related to Bacteria or Viruses. Identify the independent and dependent variables.

Answers

Answer:

An experiment where an antibiotic is tested against bacteria. The antibiotic can vary in its concentration for example, different amounts are applied to a sample of bacteria to see if it is affected by the action of the antibiotic and if so, in what concentration. So, the independent variable is the concentration of antibiotic while the dependent variable is the survival (or not) of the bacteria.

Explanation:

An independent variable is a variable that represents a quantity that the scientist modifies in an experiment. A dependent variable represents a quantity whose value depends on how the independent variable is modified. This is the variable being studied and measured.

So, an example of this applied to bacteria or viruses could be:

An experiment where an antibiotic is tested against bacteria. The antibiotic can vary in its concentration, different amounts are applied to a sample of bacteria to see if it is affected by the action of the antibiotic and if so, in what concentration. So, the independent variable is the concentration of antibiotic while the dependent variable is the survival (or not) of the bacteria.

To complete the experiment, an antibiotic whose effect is already known can be used as a positive control. That is, it is already known to kill the bacteria. And as a negative control you can simply use water, which has no effect and is known not to kill the bacteria. In this way, we validate the results and make sure that there is not something else that is affecting the bacteria and that only the antibiotic being studied has an influence.

_____ allows the cell to grow larger and replicate its DNA in order to prepare for cell division, known as _________. The __________ is the cell that divides to become two new _________.

Answers

Answer:

_Mitosis_ allows the cell to grow larger and replicate its DNA in order to prepare for cell division, known as __meiosis__. The __parent cell_ is the cell that divides to become two new _daughter cells__.

Explanation:

The excerpt explains cell division. Let us define some of the terms used:

Mitosis: Mitosis is a stage in the cell cycle where a parent cell divides/replicates into two identical daughter cells. They are identical because they contain the same number of genetic information after division. Mitosis is responsible for cell growth in all somatic cells

Meiosis: Meiosis is a type of cell division in germ (reproductive) cells where the parent cell divides into two daughter cells which contain half the number of genetic information (haploid) as the parent cell.

Parent cell: This refers to the original cell that undergoes division into two or more daughter cells

Daughter cells: The daughter cells are the resulting cells produced after cell division.

For a better understanding of the whole cell division cycle, please read-up the stages contained in both the mitosis and meiosis.

C.The oceans would contain more carbonic acid.
D.There would be more ice on Earth's surface.

Answers

Answer:

I think the answer will be:

D. There would be more ice on Earth's surface.

Explanation:

Without the greenhouse effect, the Earth would have an average temperature of -18°c and life would not be able to survive.

The Earth would be different if the greenhouse gasses didn't even exist.

The Earth's surface would be covered in more ice.

So, option D. is correct.

Define greenhouse effect.

The greenhouse effect happens when solar energy passes through a planetary system and heats its surface, but the air prevents the energy from going directly to space, leading in a warming climate.

MITOSIS AND MEIOSIS*

Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. ... During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.

What meiosis means?

Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. ... Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome.

What is mitosis explain?

Mitosis is a process where a single cell divides into two identical daughter cells (cell division). During mitosis one cell? divides once to form two identical cells. The major purpose of mitosis is for growth and to replace worn out cells.

What is meiosis important?

Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.

What is Mitosis important?

Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged.

What is Mitosis means?

Mitosis is a process where a single cell divides into two identical daughter cells (cell division). ... The major purpose of mitosis is for growth and to replace worn out cells.
