1 answer:

3 0

Crowdsourcing is a practice wherein a person or group or person engage a crowd or group for a common goal for the purpose of innovation, problem solving or efficiency. New technologies, social media and web 2.0 are used in crowdsourcing. The following are the disadvantages of cowdsourcing: (1)Confidentiality and security. This is the deadliest disadvantage of crowdsourcing. It is essential to keep certain things from competitors but in crowdsourcing, you are dealing with large and anonymous group of people in there may be a malefactor or a direct competitor. (2) Communication. It can be difficult due to time and language barriers. (3) Management. There is an increased need of management because it will mean dealing with a large number of people. (4) Approach. Crowdsourced people may not be as serious or interested. They may not be paying very close attention because they are deeply involve in the project. (5) Quality. There is no guarantee that the result will be of sufficient quality or effective. Some of the respondents may cheat because some of them may just submit copied or plagiarized ideas

What are the four types of tissues?

ElenaW [278]

The term ''tissue'' refers to a group of similar cells. Being a combination of equal cells, a tissue has the same function in any part of the body.

The four types of tissues are:

. The epithelial tissue

. The connective tissue

. Muscle tissue

. The nervous tissue

. The epithelial tissue serves as a cover, among these are the skin and the lining of several ducts inside the body. It is divided into two general classifications: Simple Epithelium and Stratified Epithelium.

. The connective tissue supports and joins other tissues such as bone, blood and lymphatic as well as adipose tissue and reticular tissue.

. Muscle tissue consists of striated or voluntary muscles that move the skeleton and smooth muscle, such as the one that surrounds the stomach. It is divided into three types: Skeletal Muscle Tissue, Cardiac Muscle Tissue and Smooth Muscle Tissue.

. Nervous tissue is formed by nerve cells or neurons and serves to carry messages to and from various parts of the body. This tissue is present mostly in the brains and spinal cord. It has two types of tissue: The Nerve Cell and the Neuroglia.

Lelu [443]

The question is incomplete. Complete question is as follows :

What is/are the phenotype(s) of the recombinant offspring of the F2 generation?

Parental generation: True-breeding flies with red eyes and long wings were crossed to flies with white eyes and miniature wings. All F1 offspring had red eyes and long wings.

The F1 female flies were then crossed to males with white eyes and miniature wings. The following results were obtained for the F2 generation:

129 red eyes, long wings

133 white eyes, miniature wings

71 red eyes, miniature wings

67 white eyes, long wings

Answer:

Red eyes, miniature wings and white eyes, long wings

Explanation:

In absence of linkage parental and recombinant offspring are produced in equal number. When there is linkage crossover does not take place in expected frequency so recombinants are produced in lesser number than parental type offspring.

Here in F2 generation red eyes, miniature wings and white eyes, long wings are produced in lesser number (71 and 67). Also the original parents had red eyes, long wings and white eyes, miniature wings. Hence, Red eyes, miniature wings and white eyes, long wings are the phenotype of the recombinant offspring of the F2 generation.

In a particular plant, green seed color is dominant to yellow seed color. If a homozygous

Sergio039 [100]

Answer: 100% will be heterozygous green.

Explanation:

Since both parents (green and yellow) are homozygous and green is dominant, when they are crossed all the resultant offsprings will have both genes of green and yellow in their genotype but will appear as green( phenotype) because the green colour is dominant and has masked the yellow colour which is recessive.

Which molecule is responsible for the wide diversity of life on earth?

Elden [556K]

A phylogeny is an evolutionary ”tree” of related
organisms that can be constructed by using
information obtained from the genetic material.
Genetic information is contained in all living cells,
in the form of long DNA molecules that take the
shape of connected double- stranded spirals
(DNA stands for deoxyribonucleic acid). DNA
spirals, or “helixes”, are tightly compressed in the
nucleus of every cell. Their information is
organized into a code made up of four small
molecules — the building blocks of DNA. The
molecules, called nucleotides, are labelled:
A (adenine), C (cytosine), G (guanine) and T
(thymine).
It is possible to draw conclusions about the
evolution of a group of plant or animal species,
and the relationships among them, by comparing
selected pieces of DNA.
