Answer:
Glucagon is released to stop blood sugar levels dropping too low (hypoglycaemia), while insulin is released to stop blood sugar levels rising too high (hyperglycaemia). The release of glucagon is stimulated by low blood glucose, protein-rich meals and adrenaline (another important hormone for combating low glucose).

Transcription requires an RNA template while translation uses a DNA
template.
Transcription is performed by prokaryotes while translation' is performed by
eukaryotes.
Transcription occurs in the nucleus while translation occurs in the
cytoplasm in eukaryotes.
Transcription produces an mRNA molecule while translation converts the
code from mRNA into a protein
Transcription require RNA polymerase while translation requires ribosomes
to build their end product molecules.
D)
E)
Answer: c) Transcription occurs in the nucleus while translation occurs in the cytoplasm in eukaryotes, D) Transcription produces an mRNA molecule while translation converts the code from mRNA into a protein, E) Transcription require RNA polymerase while translation requires ribosomes to build their end product molecules
Explanation:
The central dogma of molecular biology involves two cellular processes, transcription and translation. The process occurs at different sites in the eukaryotic cells.
The correct options are:
Option C: Transcription occurs in the nucleus while translation occurs in the cytoplasm in eukaryotes
Option D: Transcription produces an mRNA molecule while translation converts the code from mRNA into a protein
Option E: Transcription requires RNA polymerase while translation requires ribosomes to build their end product molecules
The explanation for transcription and translation can be given as:
1. Transcription takes place in the nucleus, whereas translation occurs in the cytoplasm of a eukaryotic cell.
2. Transcription is the process of decoding the message from DNA to mRNA. Translation occurs after transcription, in which messages coded into mRNA are converted into polypeptides.
3. The enzymes are essential for catalyzing processes like transcription and translation. The transcription is carried out by RNA polymerase, whereas translation requires ribosomes to build products.
Thus, translation and transcription are the two parts of the central dogma.

When 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.

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.
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.

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.

These are Vitreous gel, Optic Nerve, Macula, Fovea, Retina, Lens, Pupil, Cornea, Iris respectively.
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.

How does a cladogram represent hypothesized evolutionary relationships?
Answer:
A cladogram is used by a scientist studying phylogenetic systematics to visualize the groups of organisms being compared, how they are related, and their most common ancestors. Cladograms represent hypotheses about the evolution of organisms and are subject to revision when theories are disproved and additional data become available.

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.
