zmey [24]
The answer is <span>All of their offspring will have dimples.
</span>
A - dominant allele for having dimples
a - recessive allele for not having dimples

AA - individuals with dimples     (mother in our case)
Aa - individuals with dimples      (father in our case)
aa - individuals without dimples    

The cross would look like this:
Parents:      AA      x      Aa
Children: AA    AA    Aa    Aa

So, all of the offspring will have dimples

Which of the following describes a benefit of membership in a research community?
mezya [45]

D. An expensive instrument is shared by scientists at a university describes the benefit of membership in a research community

Explanation:

A membership in a research community like university research group is a huge benefit for the researcher.

One of the main advantage is sharing of expensive equipment among the members. The university will be equipped with most of the latest equipment necessary to conduct research like supercomputers, latest imaging equipment, manufacturing units, etc which would otherwise be inaccessible to an individual researcher. The researcher can utilize this huge benefit to conduct various experiments needed for his/her research.

These memberships provides a lot of opportunities to interact with fellow researchers, scientists etc, it provides a platform to showcase each one's research, to discuss various merits and demerits of the research, and to know about other valuable information shared by others.

You see a structural formula in which the symbols for elements are connected by a long dash. You can assume that the chemical bo
masha68 [24]

The correct answer is option B, that is, covalent bonds.  

Covalent bonds are more prevalent in organic chemistry in comparison to ionic bonds. A covalent bond comprises of the concurrent attraction of two nuclei for one or more electron pairs. The electrons situated between the two nuclei are known as bonding electrons.  

Covalent bonds take place between different atoms or similar atoms whose difference in electronegativity is not enough to permit the transfer of electrons to produce ions. The covalent bond is demonstrated by either as a solid line or long dash or as a pair of dots.

What do having the measles and being vaccinated against the measles have in common?
photoshop1234 [79]

They are both forms of active immunity.

<h3>What is active immunity?</h3>

When our own immune system defends us against a pathogen, this is known as active immunity. Our immune system develops active immunity when exposed to a potential disease-causing substance (i.e., pathogen). Active immunity is crucial since it not only "fights off" these pathogens but also lasts a very long period in the form of immunologic memory.

B and T lymphocytes with the ability to recognize a particular pathogen make up immunologic memory. These cells circulate at low levels in human bodies, but if they become "activated" by encountering the pathogen while traveling, they rapidly begin to multiply and send signals to other immune system components to do the same. There are two reasons memory cells are important. They first help our immune systems react swiftly. The immune response is prepared the moment the infection is contacted since they are secondly pathogen-specific.

I understand the question you are looking for is this:

What do "having the measles" and being vaccinated against the measles have in common?

  1. They are both forms of active immunity.
  2. They are both forms of neutral immunity.
  3. They are both forms of passive immunity.
  4. They are both forms of infection.
  5. They are both forms of immune deficiency.

What is kinetic energy and how is kinetic energy related to the temperature of a substance?
Jet001 [13]

Answer:

Kinetic energy is a property of a moving object or particle and depends not only on its motion but also on its mass. The temperature of gases is proportional to the average translational kinetic energy of atoms and molecules. The motion of individual molecules in a gas is random in magnitude and direction.
