When two different sperm fertilize two eggs,

a.) fraternal twins result.
b.) identical twins result.
c.) twins of different sexes always result.
d.) twins of the same sex always result.

Answers

Answer 1

Answer:

When two different sperm fertilize two eggs, fraternal twins result (option a).

Explanation:

Fraternal twins are the result of the separate fertilization of two maternal eggs by two paternal sperm, with the obtention of two zygotes with different DNA.

Although the embryonic development of fraternal twins occurs at the same time in the maternal uterus, each embryo will have an individual placenta and embryonic sac, with different development and characteristics, sometimes including sex.

The other options are not correct because:

    b. Identical twins come from the division of the zygote after fertilization, obtaining siblings with the same DNA and who share the same placenta and embryonic sac.

    c. Twins of a different sex do not always occur.

    d. Same sex twins always occur when they are identical twins.

3- While a one-rep maximal test is an effective way to measure muscular strength, testing for muscular endurance is trickier. One way to test endurance is through exercises that ask you to lift a certain percentage of your body weight. For example, the pushup test, in which you see how many pushups you can complete in a set amount of time, is a common test of muscular endurance. Another way is to lift a fixed percentage of your one-repetition max for a certain exercise – such as measuring how many weighted squats or bench presses you can complete in 60 seconds.

Which of the following is an EXOGENOUS source of injury to a cell?
A fever
B bacterial toxins.
C ultraviolet radiation.
D genetic malformation

Answers

Answer:

C. ultraviolet radiation.

Explanation:

Cell injury occurs when cells undergo specific changes when subjected to an internal factor or an external factor. Such change causes "illness" to the person.

Under "toxic injury," two sources may cause an injury to the cell. These are endogenous and exogenous factors. Endogenous factors originate within the body while the exogenous factors originate from the environment.

Among the choices above, it is only the ultraviolet radiation that is considered an exogenous factor because it originates from outside the person's body. Prolonged exposure to UV light damages the cells which can lead to cancer.

Here people would be getting useful tips to continue their lives and clubs would be there , where people can discuss their growth , their income , their spiritual growth and the tips and tricks they use to lead a happy life . This way people would start to develope a friendly nature , a helping attitude and gratitude towards those who helped them . This would help improve the social and moral values of my community . I would also create free red talks on the topics which are most difficult to catch , so that people would be abke to get their hans on resources which are otherwise too expensive to purchase . I would call scholars who are willing to give free support to the community and ask them to provide free lectures . I would provide a certificate to the people who volunteered . This way people in my community will be benefitted and those who volunteered will experience a moment of truth ( in marketing it is said to be a way in which someone becomes a trusted or loyal member of a program or organization ) . To keep my community people involved in my program I would give some freebies that are attractive to sight so that they would frequent my program .
