The mechanics of pterosaur flight is still not clear, three features of S. crassirotris' skeleton are:
1. Pterosaur bones were hollow and air-filled, like the bones of birds.
2. They had a keeled breastbone that was developed for the attachment of flight muscles and an enlarged brain that shows specialised features associated with flight.
3. The backbone over the shoulders fused into a structure known as a notarium, which served to stiffen the torso during flight, and provide stable support for the scapula.
What time period did the Scaphognathus live in?Scaphognathus live, 167.7 million years ago - 145 million years ago in Germany.
Hence, they have hollow and air-filled bones, keeled breastbone and notarium to flying.

Developmental psychologists investigate topics such as language acquisition in childhood, biopsychological changes experienced by adolescents, cognitive functioning in old age, etc.
2. How do adolescent brains develop?---> B. Biopsychology
Biopsychology refers to branch of psychology that investigates the biological basis or influence on our behavior. Specifically, biopsychology examines how brain anatomy and function influence our behavior, how hormones influence our behavior, how physical deformities in the brain affect behavior, the role of genetics in behavior, etc. A biopsychologist might study topics such as the effect of suffering a stroke on behavior and cognition, how brain abnormalities are linked to mental or learning difficulties, the influence of genetics on personality, etc.
3. How can I lead a happier life?---> A. Positive psychology

Which of the following will most likely happen to these rodent populations over time?
A:The populations will become two different species.
B :The populations will learn to live on top of the soil.
C:The population with the highest birth rate will move to the other soil type.

Exocytosis is a process by which cells A. remove bulk material from the cell via wosicions
B. remove bulk material from the cell via pores C. bring bulk material into the cell via vesicles D. bring bulk material into the cell via pores
Exocytosis is the process by which cells B. remove bulk material from the cell via pores
The prefix, "exo" suggests "out" or "external". Also, the suffix, "cytosis" relates to anything that has to do with cells.
Exocytosis in concise terms can be described as the movement of large polar molecules and waste materials out of a cell through pores by active/bulk transport mechanism. This mechanism is the opposite of endocytosis.
The process involves:
the formation of an encapsulated membrane, which is a vesicle formed within the cell containing the packaged materials that is to be expelled.the vesicle is moved to the cell membranethe vesicle is expelled through the pores and the contents are released out of the cell.See attachment for image showing the mechanism of Exocytosis.
Thus, the right option is B. remove bulk material from the cell via pores.

What is structure of eye?Three coats enclose the optically clear aqueous humour, lens, and vitreous body in the eye.
The cornea and sclera form the outermost coat; the choroid, ciliary body, and iris form the middle coat, which contains the main blood supply to the eye and extends from the back to the front.
The eye functions as a sensory organ. It collects light from our surroundings and converts it into nerve impulses. The optic nerve sends these signals to the brain, which creates an image and thus provides sight.
Thus, as per the labeling number, Vitreous gel, Optic Nerve, Macula, Fovea, Retina, Lens, Pupil, Cornea, Iris respectively are the parts of eye.

When Anna eats an apple, the sugars in that apple are broken down into the substance called glucose. Glucose is then burned in her body for energy. One of the body parts that needs this energy is the heart, which beats due to electrical impulses. A byproduct of this glucose breakdown is the heat that warms her body and is later released.
Which identifies the energy transformations that take place in Anna’s body as this process takes place?
A.) Mechanical energy is converted to kinetic energy, which is then converted to potential energy.
B.) Chemical energy is converted to thermal energy and electrical energy.
C.) Electrical energy is converted to chemical energy and thermal energy.
D.) Mechanical energy is converted to potential energy which is then converted to kinetic energy.

Which of the following solar phenomena is thought to cause short term climate changes?
A) solar flares
B) prominences
C) sunspots
D) solar winds
Answer:
Solar flares
Explanation:
The magnetic field lines near sunspots often tangle, cross, and reorganize. This can cause a sudden explosion of energy called a solar flare. Solar flares release a lot of radiation into space. If a solar flare is very intense, the radiation it releases can interfere with our radio communications here on Earth.
true or false? Embryonic stem cells are more limited in what they can become than somatic stem cells
Answer:
true
Explanation:
Embryonic stem cells.
These are pluripotent (ploo-RIP-uh-tunt) stem cells, meaning they can divide into more stem cells or can become any type of cell in the body. This versatility allows embryonic stem cells to be used to regenerate or repair diseased tissue and organs.
