The focus on neuroscience box "brain reward when making eye contact with attractive people" describes an fmri study. the results

showed that when we make direct eye contact with a physically attractive person, a specific area on each side of the brain is activated. when the attractive person's eye gaze is shifted away from the viewer, brain activity in these areas decrease. other researchers have expanded on these findings and identified additional brain areas that are selectively responsive to the reward value of attractive faces. these are the:

Can you list the types of organisms in order in which they would appear during primary succession?
nignag [31]

Answer:

Primary succession is one type of the ecological succession which takes place on the land devoid of vegetation or barren land.

The species which first flourishes on this barren land are known as pioneer species which includes the species of bryophytes and pteridophytes like lichens and mosses.

These lichens and mosses help breakdown the barren rocks through chemical leaching and help increase the nutrient content. This allows the ferns and small pteridophytes to grow.  

Then the area is colonized by the intermediate species which includes herbs, shrubs later trees. These intermediate species help attract the animals and thus help establish the biological community.

Thus, Lichens mosses → herbs→ shrubs →trees.

Explain why offspring of plants exposed to radiation may have characteristics not found in the original population.
iVinArrow [24]
Radiation can damage DNA. This could result in a change in the proteins which make up the plant's physical structure. 

<span>For example, a plant might have a gene for purple pigment which makes its flowers purple. Radiation might change the DNA sequence so that the directions for making the purple pigment tell it to stop prematurely, and the result might be white flowers rather than purple flowers.</span>

Why are pigments such as chlorophyll needed for photosynthesis
Vlad [161]

Answer:

The chlorophyll pigment have photosystem 680/ PS I which captures the sunlight. Then the pigments gets excited and photosynthesis starts. Without chlorophyll photosynthesis can't happen.

Explanation:

Photosynthesis occurs in the chlorophyll pigment of the plant. They have the capacity to trap light energy and convert its energy to form glucose and oxygen.  

The chlorophyll is a double layer membrane structure. In it two photosystems works i.e. photosystem I and photosystem II. In the photosystem I light is trapped.  

In the chlorophyll thylakoids are present which have photosystem 680. It captures the photons coming from the sun. The photons are the light of different wavelengths which are absorbed by plants.  

The photon have more energy, and when it comes in contact with PS 680, the pigments get excited. Then they release high energy electrons which helps to form ATP, NADPH. Because it is a light dependent reaction.

Glucose and oxygen are formed in the stroma as it does not require light. It is a light independent reaction.

Therefore, chlorophyll is first require to capture photons coming from sun.

Many kangaroo rats live in the Sonoran desert of the southwestern United States. They have a variety of adaptations for living i
SVETLANKA909090 [29]

Adaptations. The kangaroo rat is almost perfectly adapted to life in the desert. They can survive without ever drinking any water, getting needed moisture from their seed diet. They have excellent hearing and can even detect the silent sound of an owl approaching.

Hope this helps!

BTW can I have brainliest for all the effort I put into writing all of this?
