Why do you think some animals can reproduce in large number?
Why do you think some animals can reproduce in large number?
Answer. Explanation: A single individual can produce offspring asexually and large numbers of offspring can be produced quickly. The genetic diversity of sexually produced offspring is thought to give species a better chance of surviving in an unpredictable or changing environment.
What did you notice to the offspring when produced sexually?
Answer: During sexual reproduction, the genetic material of two individuals is combined to produce genetically diverse offspring that differ from their parents. Only half the population (females) can produce the offspring, so fewer offspring will be produced when compared to asexual reproduction.
What are the 2 types of budding?
Chip budding and T-budding are the two most important types of budding for woody ornamentals and fruit trees (see Table 13–1, page 522). Chip and T-budding are much simpler and, therefore, much faster than manual grafting techniques.
What is a budding romance?
A romance that is just beginning and looks promising.
What is life history method?
Life history interviewing is a qualitative method of data collection where people are asked to document their life over a period of time. It is a personal account of their life, in their own words and using their own personal time lines.
What are the 3 basic forms of life history method?
Making another set of distinctions, Allport (1942) suggested three main forms of life history writing: the comprehensive, the topical, and the edited.
What are the three types of budding?
The different methods of budding:
- T-Budding:
- Inverted-T-Budding:
- Patch Budding:
- Ring Budding:
- Chip-budding:
- Forkert Budding:
What is an Autoethnography dissertation?
This qualitative dissertation uses autoethnography as the methodology. Autoethnography is research, writing and story where the researcher is the subject and the researcher’s experiences are the data (Ellis and Bochner 2000).
What is Agamogenesis?
Agamogenesis: reproduction without fertilization by a male: see parthenogenesis; gamogenesis.
Is it possible for humans to undergo asexual reproduction Why?
Humans cannot reproduce with just one parent; humans can only reproduce sexually. Bacteria, being a prokaryotic, single-celled organism, must reproduce asexually. The advantage of asexual reproduction is that it can be very quick and does not require the meeting of a male and female organism.
Is said to be budding bacteria?
Budding bacterium, plural Budding Bacteria, any of a group of bacteria that reproduce by budding. Each bacterium divides following unequal cell growth; the mother cell is retained, and a new daughter cell is formed.
What are the 4 types of asexual reproduction?
There are a number of types of asexual reproduction including fission, fragmentation, budding, vegetative reproduction, spore formation and agamogenesis.
What is a life history trade off?
A trade-off exists when an increase in one life history trait (improving fitness) is coupled to a decrease in another life history trait (reducing fitness), so that the fitness benefit through increasing trait 1 is balanced against a fitness cost through decreasing trait 2 (Figure 2A).
What is yeast budding?
Budding is a type of asexual reproduction in which a new organism develops from an outgrowth or bud due to cell division at one particular site. The small bulb-like projection coming out from the yeast cell is called a bud.
What is the advantage of budding?
Budding is most frequently used to multiply a variety that cannot be produced from seed. It is a common method for producing fruit trees, roses and many varieties of ornamental trees and shrubs. It may also be used for topworking trees that can’t be easily grafted with cleft or whip grafts.
What animals can impregnate themselves?
“It is believed that it can be hard for them to find a mate, and selfing is better than not producing at all.” Other creatures that can impregnate themselves include the New Mexico whiptail lizard and the Komodo dragon, which is also known to mate with their male offspring.
Which plants are used for budding?
In fruit trees, T-budding or Chip budding are grafting techniques that use a single bud from the desired scion rather than scionwood with multiple buds. Budding can be used on many kinds of plants: apples, pears, peaches, and a large number of ornamentals.
What animals can reproduce in large number?
Selina Heppell, head of the Department of Fisheries and Wildlife at Oregon State University, says other fish known to have high numbers of eggs include sturgeon (up to 2.5 million eggs for Atlantic sturgeon) and large tuna (bluefin tuna can produce 10 million eggs a year).
What was the first organism to reproduce sexually?
The rocks were deposited in marine tidal environments 1.2 billion years ago and they contain fossils that tell us about the first sexual reproduction. A fossil called Bangiomorpha pubescens is a multicellular organism that sexually reproduced, the oldest reported occurrence in the fossil record.
How do you write a dissertation content?
Writing and structuring your dissertation
- An introduction to your topic.
- A literature review that surveys relevant sources.
- An explanation of your methodology.
- An overview of the results of your research.
- A discussion of the results and their implications.
- A conclusion that shows what your research has contributed.
How is budding carried out?
Budding is a grafting technique in which a single bud from the desired scion is used rather than an entire scion containing many buds. Most budding is done just before or during the growing season. However some species may be budded during the winter while they are dormant.
What is budding and example?
Budding is an asexual mode of producing new organisms. In this process, a new organism is developed from a small part of the parent’s body. A bud which is formed detaches to develop into a new organism. For example- Both hydra and yeast reproduce by the process of Budding.
Who first used the method of life study method?
The landmark of the life history method was developed in the 1920s and most significantly embodied in The Polish Peasant in Europe and America by W.I Thomas and Florian Znaniecki. The authors employed a Polish immigrant to write his own life story which they then interpreted and analyzed.
How many offspring can an individual have in a lifetime?
Here’s how many children you can have in a lifetime. There is a limit to how many children one person can have, but that number is much higher for men than it is for women. One study estimated a woman can have around 15-30 children in a lifetime, taking pregnancy and recovery time into account.
What is an example of a trade off?
In economics, a trade-off is defined as an “opportunity cost.” For example, you might take a day off work to go to a concert, gaining the opportunity of seeing your favorite band, while losing a day’s wages as the cost for that opportunity.
