Which structure found in humans only in the embryonic stage shows that humans are related to other species?
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.
I need help 1 more time How does the Sun manage to maintain an environment in its core that is conducive to nuclear fusion? I'll mark 1 more Brainliest so plz I really need this done before Monday
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.
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 innards and the pressure pushing outward . it keeps the sun's size, denseness, and hotness stable, thus making nuclear fusion possible.

If brown hair is represented by the allele "B" and blond hair is represented by the allele "b" then what must the genotype(s) be of someone who has brown hair?
Answer:
Bb or BB
Explanation:
since brown hair was the dominant allele it only has to have one big B to serve as a heterozygous dominant trait. Therefore, the person has brown hair. If you were looking for blond hair it would have to be bb because it is a recessive trait and you need two recessive traits to make up a certain genetic trait.

The atoms of certain element each contain 36 protons and 8 valence electrons. Which statement correctly identifies this element and describes its chmical reactivity?
Answer:
This question lacks options, the options are:
A The element is krypton, Kr, and it is not very reactive.
B The element is chlorine, Cl, and it is highly reactive.
C The element is krypton, Kr, and it is highly reactive.
D The element is chlorine, Cl, and it is not very reactive.
The correct answer is A
Explanation:
An atom is identified by its atomic number, which is the number of protons it contains. In this question, it is said that the atoms of a certain element each contain 36 protons. Using the periodic table, the element with atomic no. 36 is KRYPTON.
Also, Krypton posseses 8 valence electrons in its outer shell. In accordance to the octet rule, Krypton has no further need to engage in any chemical reaction to fill its electron shell because it is already filled (8 valence electrons). This accounts for the reason Krypton belongs to "Noble gases" and very unreactive.

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
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.
which of the following is correct about cells?
Answer:
The answer is the c part that states, in prokaryotes, there are no membrane-bound organelles.
The organelles are surrounded by the single or double membranes such as Lysosomes, mitochondria, nucleus, Golgi Bodies, chloroplasts, Endoplasmic Reticulum and so on.
However, these all are not present in the prokaryotes type of cell.
