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.

Explain the changes that are taking place in the frog population shown in the image.. Provide an example of a selection pressure that could have led to this change. What type of selection would this show?
Answer:
The male frog call in this population has diverged significantly from both the northern and southern lineage calls. "If females have a reason not to get the mating wrong, and they have some way of telling the males apart - the call - the theory is that this should create evolutionary pressure for the female choice to evolve so that they pick ...

What is the longest phase in a star's life cycle?
Answer:

Explanation:
The mean temperature of the Tauri star isn't enough to support nuclear fusion at its core. The T-Tauri star lasts for about 100 million years, following which it enters the most extended phase of development – the Main sequence phase.
What characteristics would you look for to determine if an organism is a protist or a plant?
Answer:
A few characteristics are common between protists.
They are eukaryotic, which means they have a nucleus.Most have mitochondria.They can be parasites.They all prefer aquatic or moist environments.Explanation:I HOPE ITS HELP
Protists are eukaryotes, which means their cells have a nucleus and other membrane-bound organelles. Most protists are single-celled. Other than these features, they have very little in common. You can think about protists as all eukaryotic organisms that are neither animals, nor plants, nor fungi.

what is bi cuspid valve and where it is present?
Answer:
Bicuspid aortic valve is a type of abnormality in the aortic valve in the heart. In bicuspid aortic valve, the valve has only two small parts, called leaflets, instead of the normal three. This condition is present from birth. It can occur with other heart defects. The heart's ventricles are the two lower chambers of the heart.
location :
Bicuspid valve is one of the four valves of the heart which is situated between the left atrium and the left ventricle. Tricuspid valve is one of the four valves of the heart which is situated between the right atrium and the right ventricle. Bicuspid valve is present in between the left atrium and the left ventricle.

Embryonic stem cells are undifferentiated cells. They can grow and divide giving rise to any type of tissue in a developing embryo. What must be true of the DNA in an organism's stem cells?
Answer:
Stem cells cut and repair their own DNA to promote formation of new tissues.
Explanation:
Stem cells cut itself and then repair their own DNA as a mechanism of activating genes that promote the development of new tissues. Stem cells are special type of cells that the ability to develop into many different types of cell such as muscle cells, brain cells etc. These cells are also capable to repair damaged tissues in the body.

behavioral changephysiological changechemical changes in samples, etcWhen the availability of resources in an area is limited, organisms may leave a population to move to an area with more resources. What is this movement called? birth rate death rate O emigration immigration
Answer:
Emigration immigration
Explanation:
Emigration means an animal leaves its home because the habitat is no longer ideal for them, and they need to find a more suitable environment. Animals that immigrate or emigrate do not return to the land they left.
When the availability of resources in an area is limited, organisms may leave a population to move to an area with more resources, so the movement is called as Emigration. So, the correct option is C.
What is Emigration?Emigration is defined as the act of leaving one resident's country or place of residence with the intention of settling elsewhere while immigration describes the movement of people from one country to another. A migrant emigrates from his old country, and immigrates to his new country.
Emigration affects the economies of the countries which is involved in both positive and negative ways depending on the current state of the countries' economies. This has an economic impact on the countries involved, including the workforce and consumer spending.
Therefore, the correct option is C.

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.

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.
