Answer:

C. Non-covalent interactions between the protein and specific bases in the major groove of DNA

Explanation:

Activator or repressor proteins are proteins with specific DNA-binding domains that have affinity by one or two DNA strands. In general, these proteins interact with the major groove of the B-DNA structure since this structure exposes more functional groups for binding. Non-covalent interactions are a type of interaction that does not involve the sharing of electrons. The interaction between proteins and DNA is due to the combination of different non-covalent interactions, which can be classified into four major types: van der Waals, hydrophobic, hydrogen and ionic interactions.

Answer:

Gymnosperms

Explanation:

Gymnosperms produce both male and female cones, each making the gametes needed for fertilization; this makes them heterosporous. Megaspores made in cones develop into the female gametophytes inside the ovules of gymnosperms, while pollen grains develop from cones that produce microspores.

Gymnosperms are name of the group of spermatophytes that are cone-bearing plants. The correct option is C.

In contrast to angiosperms, or flowering plants, whose seeds are encapsulated by mature ovaries or fruits, a gymnosperm is any vascular plant that propagates through a bare seed, or ovule.

Many gymnosperm seeds are borne in cones and are not visible until the plant matures.

Gymnosperms are a small class of plants that rarely flower and produce "bare seeds." This means that the seeds are produced on the reproductive structure's surface rather than within it, as in a fruit.

Gymnosperms are a spermatophyte plant group that includes cone-bearing plants.

Thus, the correct option is C.

Answer: A cookie contains a lot of processed simple sugars.

Answer:

Gravitropism (also known as geotropism) is a coordinated process of differential growth by a plant or fungus in response to gravity pulling on it. Gravity can be either "artificial gravity" or natural gravity. It is a general feature of all higher and many lower plants as well as other organisms.

Answer:

The map distance = 33.3 cM

Explanation:

Let us take,

BBLL  as blue shell, long antenna .........Parent 1

bbll  as green shell, short antenna .......... Parent 2

Then, cross between parent 1 and parent 2, which is

BBLL X bbll

The F1 generation will be heterzygous

BbLl as blue shell, long antenna ...... F1 offspring

By the test cross,

BbLl X bbll :

given,

BL/bl = 82 : Parental

bl/bl = 78 : Parental

Bl/bl = 37 : Recombinant

bL/bl = 43 : Recombinant

Total = 240

Recombination frequency =  {  [tex]\frac{Number of recombinants}{Total offspring}[/tex]}*100

= (80/240)*100 = 33.33 %

Thus, the map distance = 33.3 cM

Answer:

D. very little precipitation and few, specialized plants

Explanation:

its the answer on edge

The two characteristics which polar and dry climates have in common include very little precipitation and few specialized plants. Thus, the correct option is D.

A polar climate is a place where the climate generally has a temperature below the freezing, icy, and it is covered in snow. These areas do not get enough amount of direct heat and sunlight from the sun. Polar climates are located at the North Pole of the Arctic, and at the South Pole on the continent of Antarctica.

The dry climate are found in deserts which are very dry and the temperature of these areas are very high.

Both of these climates show some common characteristics such as very little precipitation and few specialized plants which can survive in these conditions.

Therefore, the correct option is D.

Explanation:

The field of forensic science is important to the criminal justice system. Forensic personnel must pay close attention to detail during the collection, preservation, and analysis of physical evidence. If evidence is mishandled, manipulated, or misinterpreted it can potentially destroy a case and/or the lives of all individuals involved

Answer:

Explanation:

In 1904, Scotland Yard officials introduced fingerprint matching to US law enforcement officials at the World’s Fair. The fact that forensic science was not born from the scientific community meant that forensic scientists were not always bound to the quest for knowledge, but instead for the purpose of solving crimes. This difference led to misaligned incentives. Expert witnesses were often paid per conviction in many states.

In the late 1980s, DNA evidence, which was born in the scientific community, has helped identify the guilty and exonerate the innocent. Many other forensic techniques, such as hair microscopy, ballistics analysis, and arson investigations, have not been subjected to the rigorous scientific evaluation that DNA analysis has. Other techniques, such as blood typing, have been properly validated.

These invalidated techniques have led to the Innocence Project, which holds that forensic science techniques should be shown to be valid and reliable through research and assessment of validity and reliability, and subject to accreditation and certification to assure quality. States are eligible to receive grant money if they do so. This change has resulted in the growth of many organizations, such as the ASCLD/LAB, that accredit forensic scientists.

The indigenous 'medicine man' flees seeing Dr. Campbell because both Dr Campbell and the medicine man, were in conflict with each other.

Explanation:

'Medicine Man' is a movie directed by John McTiernan, starring Sean Connery(as Dr. Robert Campbell) and Lorraine Bracco(as Dr. Rae Crane). The film is about Dr. Campbell who sets into the forest of Amazon and finds the cure to cancer.

The Medicine man is the one who informed Dr. Campbell about the flowers containing 'ju-ju' (powers to heal). But after Campbell cured a little boy having gas by 'alka-seltzer', they both were in conflict of each other.

So, when Dr. Campbell showed up with the man and a little boy suffering from malignant neoplasms at the medicine man doorsteps, the indigenous medicine man flees from there.
