Answer:

Highlights:

*Researchers in the sciences do not see access to the scientific literature as an especially important problem.

*Authors consider factors such as journal reputation and the absence of publication fees when deciding where to submit their work. In contrast, free access is not a significant factor in their submission decisions.

Implications:

*While open access has the potential to expand the authorship and readership of the scientific literature, that potential has not yet been realized.

*Librarians who encourage scientists to publish in open access journals should be aware of the authors' priorities and perspectives. Authors in the sciences tend to focus on citation impact, reputation, and accessibility to a specialized readership—not breadth of readership, copyright, or access status.

*Journal publishers that charge publication fees may want to consider alternative sources of revenue. Authors' resistance to publication fees is a major barrier to greater participation in open access initiatives.

Hello there!

How is density different from weight and mass you say? It's simple!

1. Unlike weight, density is composed of mass and volume.

2. By dividing the mass over the volume, you can determine an object's density, while weight is the product of mass and gravity.

There are different types of asexual reproduction:

Binary Fission

Budding

Fragmentation

Vegetative Propagation

Sporogenesis

Binary Fission

The term “fission” means “to divide”. During binary fission, the parent cell divides into two cells. The cell division patterns vary in different organisms, i.e., some are directional while others are non-directional. Amoeba and euglena exhibit binary fission.

It is one of the simplest and uncomplicated methods of asexual reproduction. The parent cell divides into two, each daughter cell carrying a nucleus of its own that is genetically identical to the parent. The cytoplasm also divides leading to two equal-sized daughter cells. The process repeats itself and the daughter cells grow and further divide.

Fragmentation

Fragmentation is another mode of asexual reproduction exhibited by organisms such as spirogyra, planaria etc. The parent body divides into several fragments and each fragment develops into a new organism.

Regeneration

Regeneration is the power of growing a new organism from the lost body part. For eg., when a lizard loses its tail, a new tail grows. This is because the specialized cells present in the organism can differentiate and grow into a new individual. Organisms like hydra and planaria exhibit regeneration.

Budding

Budding is the process of producing an individual through the buds that develop on the parent body. Hydra is an organism that reproduces by budding. The bud derives nutrition and shelter from the parent organism and detaches once it is fully grown.

Vegetative Propagation

Asexual reproduction in plants occurs through their vegetative parts such as leaves, roots, stems, and buds. This is called vegetative propagation. For example, potato tubers, runners/stolon, onion bulbs, etc., all reproduce through vegetative propagation.

Spore Formation

Spore formation is another means of asexual reproduction. During unfavourable conditions, the organism develops sac-like structures called sporangium that contain spores. When the conditions are favourable, the sporangium burst opens and spores are released that germinate to give rise to new organisms.

In asexual reproduction, a single cell is divided to produce offspring. Simple cell-by-cell division is not possible in multicellular organisms. Most of the multicellular organisms have a complex body design. They have a higher level of organization like tissues, organs and organ systems. Thus, they need a special mode for reproduction.

Advantages of Asexual Reproduction

Following are the advantages of asexual reproduction:

Mates are not required.

The process of reproduction is rapid.

An enormous number of organisms can be produced in very less time.

Positive genetic influences pass on to successive generations.

It occurs in various environments.

Disadvantages of Asexual Reproduction

The major disadvantages of asexual reproduction are:

Lack of diversity. Since the offsprings are genetically identical to the parent they are more susceptible to the same diseases and nutrient deficiencies as the parent. All the negative mutations persist for generations.

Since only one organism is involved, the diversity among the organisms is limited.

They are unable to adapt to the changing environment.

A single change in the environment would eliminate the entire species.

Asexual Reproduction Examples

Following are the examples of asexual reproduction:

Bacterium undergoes binary fission in which the cell divides into two along with the nucleus.

Blackworms or mud worms reproduce through fragmentation.

Hydras reproduce through budding.

Organisms such as copperheads undergo parthenogenesis.

Sugarcane can be grown through vegetative propagation.

Answer:

Explanation: The merging of male and female gametes during fertilization and the presence of two parents constitute sexual reproduction. The offspring differ from each other and their parents because they receive a variety of genes from both parents. The benefits of sexual reproduction include the offspring's ability to adapt to new surroundings due to genetic variation, which gives the species a survival advantage.

It is less likely that the disease will impact every person in a group. There is only one parent in asexual reproduction. The children are exact replicas of their parents and one another. Asexual reproduction has several benefits, including When conditions are favourable, the population can grow quickly because only one parent is required.

E. coli and other bacteria reproduce asexually. This has the benefit of enabling them to quickly create large numbers of bacteria. The identical genetic makeup of every microbe is a drawback. Every one of the germs would perish if an antibiotic were applied. There would be no people left. Random mutation is the sole process that can add variation to the population.

The majority of animals, including rabbits, reproduce sexually. Because the alleles that the mother and father each possess are combined in the offspring, sexual reproduction brings variety to the species. The fact that sexual reproduction requires more time than asexual reproduction is a drawback. Before the development of the progeny, a mate must be located and the egg fertilized with sperm. However, the benefits of adding genetic diversity to the species overcome this drawback. Given the diversity in the population, it's possible that not every rabbit would be afflicted if a disease struck the rabbit population. It follows that some people would live and be able to reproduce and have more children.

Answer:

A stimulus that the nervous system would react to a electrical impulse being made in response to the stimulus.

Explanation:

The system which send messages back and forth between the brain and the body is known as nervous system. It is the brain which controls all the body functions.

The changes in the environmental conditions to which the living organisms respond is defined as the stimuli. Every organisms responds when an external stimulus acts on it. The response given to the stimulus by various organisms is known as coordination.

One of the best examples for the stimulus and response is touching a hot object and withdrawing the hand. When you accidentally touch a hot object, we will withdraw our hand automatically. Here the heat of the object is the stimulus and withdrawing hand is the response.

Similarly if we are hungry, we will eat some food. It is also an example of stimulus and response.

Thus the change in the environment is the stimulus and the reaction of the organism to it is the response.

Answer: The statement that correctly compares the masses of subatomic particles in an atom such as carbon is "The mass of a neutron is slightly larger than the mass of a proton, and the mass of an electron is much smaller than that of a proton or neutron." This is because an atom such as carbon is composed of protons, neutrons, and electrons. Protons and neutrons are approximately the same mass and are much more massive than electrons. Therefore, the mass of a neutron is slightly larger than the mass of a proton, and the mass of an electron is much smaller than that of a proton or neutron.
