Which structure found in humans only in the embryonic stage shows that humans are related to other species?

Answers

Answer:

gill slits

Explanation:

gill slits is the structure which is only present in the embryonic stage of humans. The presence of gill slits tell us the information that humans are related to other organisms such as fish because fish has also gill slits in their embryonic stage. The gill slits only present in the embryonic stage and disappear when the embryonic stage is completed and new stage is started so we can conclude that gill slits is the structure which make the human resembles to other species.

Hey There!_____________________________________ANSWER:[tex]\Huge{\textbf{MEIOSIS:}}[/tex]

Meiosis is a special type of cell division, which occurs only in the germ cells during the process of development and maturation to form gametes. It consists of two successive cell divisions,

Meiosis 1 : First meiotic division, that reduces the NUMBER of chromosomes i.e. the parent cell is diploid(46 Chromosomes) and the daughter cells are haploid(23 Chromosome). It also causes genetic variation in the haploid by cross linkage.Meiosis 2 : Second meiotic division (Meiosis II) starts with two haploid parent cells and ends with four haploid daughter cells. Meiosis 2 like Meiosis 1, does not reduce the NUMBER OF CHROMOSOME that means the forming 4 daughter cells are haploid and their number of chromosome remains the same as the parent. BUT Haploid cells that go into the meiosis 2 have MORE AMOUNT OF CHROMOSOME THAN USUAL, thus MEIOSIS 2 REDUCES the amount of chromosome rather than the number of chromosome.

The DNA of the primitive germs cells is replicated prior to the meiosis 1 only and there is no replication of DNA before Meiosis 2. The four final cells reulting from the two meiotic divisions are not only haploid(i.e. containing 23 chromosome) but they are also containing 1n amount of DNA so that when the gametes fuse together forming a zygote, both the amount and number of chromosome and DNA remains SAME.

_____________________________________[tex]\huge{\text{Why is Meiosis Important?}}[/tex]

Meiosis is essential for the sexual reproduction of eukaryotic organisms because it enables genetic diversity through recombination, and the repair of genetic defects.

It contributes in genetic reassorment which ensures the genetic diversity in the offsprings. The genetic reassortment takes place by following two mechanisms:

During the prophase of meiosis 1, crossing over of genetic material between the homologous maternal and paternal chromosomes takes place which causes exchange of DNA fragments between the chromosome resulting is genetic diversity.During the anaphase of the first meiotic division, there is random distribution of maternal and paternal homologous chromosomes among the daughter cells which are produced as a result of meiotic division._____________________________________Best Regards,'Borz'

When a body dies, the decomposition process is __.

A.) a random group of event dependent mainly on the environment

B.) a predictable sequence of step-by-step events

C.) a very destructive process that has little value to the investigation

D.) a very simple process to investigate and interrupt, usually yielding little evidence

Answers

I would say B or A, though leaning towards A because body decomposition can change depending on the environment (temperature for example)

When a body dies, the decomposition process is a predictable sequence of step-by-step events.

How decomposition starts?Decomposition of human body starts several minutes after death with a step-by-step processes include;autolysisbloatactive decay ( putrefaction)skeletonization.Hence the body decomposition is a predictable stepwise process.

Answers

Answer:

Gravitational equilibrium helps maintain the environment in the Sun's core that is conducive to nuclear fusion. The Sun's gravitational equilibrium balances the gravity pulling inward and the pressure pushing outward. It keeps the Sun's size, denseness, and hotness stable, thus making nuclear fusion possible.

Read the following scenario to answer the following question. Avian influenza is a viral infection with few damaging effects that naturally occurs in wild birds. However, avian influenza is highly contagious and can quickly kill domesticated birds. Some human influenza viruses are similar to the avian influenza. People infected with avian influenza develop typical flu symptoms (fever, cough, muscle aches). However, symptoms may become more severe and life-threatening. If avian influenza evolves into a form that is easily transmissible from person to person, a global pandemic of widespread human death might occur. Which cells would be active during an immune response to a viral infection

Answers

Answer:

T lymphocytes, ADCC, macrophages, natural killer (NK) cells, lymphokines, and monokines.

Explanation:

T lymphocytes, ADCC, macrophages, natural killer (NK) cells, lymphokines, and monokines are the cells that are active during an immune response to a viral infection. These cells attack on the virus that is responsible for the infection. If the immune system is strong and these cells kills all viruses then no viral infection occurs while on the other hand, if these cells can't control the virus, the virus will cause infection in the body so these cells plays a vital role in prevention of infection.
