Which of these is NOT part of the digestive system?
pancreas medulla

small intestine

Answer:

The positive control is control when there is an activator present which acts as a regulatory protein so the operon and activator binds and initiates the stimulation of transcription to express the gene. In absence of this activator or regulatory protein, the operon will be inactivated.

External environmental stimuli can lead to alteration of the positive control in prokaryotes such as excess lactose in the environment. These environmental stimuli can induce transcription in prokaryotes.

In this example, if glucose is not available in the environment, the transcription of the lac operon will be induced by the presence of lactose in the environment.

Explanation:

Whenever any clinical trail is conducted then the complete process is kept unbaised. Double blind testing can be defined as an experiment in which neither the researcher nor the person who is getting placebo and who is getting treatment knows. This is done in the clinical trials to keep the whole process unbaised.

Answer:

Explanation:

because matter from both plates form the volcano....the magma is formed from the core.

Answer:

The gases and dust particles thrown into the atmosphere during volcanic eruptions have influences on climate. Most of the particles spewed from volcanoes cool the planet by shading incoming solar radiation. The cooling effect can last for months to years depending on the characteristics of the eruption.

Hope this helped, have a good day

Answer:

Volcanoes can impact climate change. During major explosive eruptions huge amounts of volcanic gas, aerosol droplets, and ash are injected into the stratosphere. Injected ash falls rapidly from the stratosphere -- most of it is removed within several days to weeks -- and has little impact on climate change

A. single-gene

Explanation:

It is controlled by a single gene that has two alleles. The allele for a widow's peak is dominant over the allele for a hairline with no peak.

Answer:

The suspicion of the students are very correct. Millipedes prefer damp environments. They need water moisture to survive.

Explanation:

Millipedes are known as arthropods. An Arthropod is an animal without a spinal vertebra, which possesses a segmented body, paired jointed appendages, and an exoskeleton.

They are found to be very ardent and quicker at recycling natural waste than animals and plants.

Without adequate moisture, Millipedes can die within 48 hours.

Explanation:

Answer:

Proteins made by free-floating ribosome's remain in that cell: whereas, proteins that travel through the endomembrane system leave by secretory vesicles.

Explanation:

A free-floating ribosome creates proteins within cells, but unlike normal ribosomes, this protein is left to float freely in the cell’s cytosol.

Furthermore, proteins that are synthesized in the rough endoplasmic reticulum will most likely be secreted into the extracellular environment.

Habitat destruction :

Habitat destruction is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or die, thereby reducing biodiversity and species abundance.

An artesian well needs the pressure of a confined aquifer.

Answer:

An Artesian well needs the pressure of a confined aquifer.

Explanation:

yes I took the test ,

The basic principle on which Artesian well is working is actually the 'pressure', hence need the pressure to get water from confined aquifer.

Answer:

Explanation:

This means all living organisms must obtain and use energy to live. Energy is the power to do things. ... A living organism can either make its food or depend on others to make food for them. For example, green plants produce their food from a process called photosynthesis.

Living things obtain energy and food to grow but different organisms do in different ways plants depend on the sun for photosynthesis.

Every living thing has a unique method of getting nutrients. Protozoans and other animals are among the creatures that obtain nutrition by eating food. Through the process of photosynthesis, plants and algae produce their own sustenance.

Animals consume food and drink to get the substance and energy they require for their biological activities.

A producer is an organism that produces its own nourishment. Sugars, a source of both energy and substance, are produced by plants using the energy from sunshine.

Therefore Plants are one type of creature that can produce its own food, to obtain energy.

#SPJ2

Answer:

The organelles found only in plant cells include- chloroplast, cell wall, plastids, and a large central vacuole. The chloroplasts contain a green pigment chlorophyll that is responsible for the process of photosynthesis. What is the composition of a plant cell wall? The cell wall of a plant is made up of cellulose

Animal cells are eukaryotic cells or cells with a membrane-bound nucleus. Unlike prokaryotic cells, DNA in animal cells is housed within the nucleus. In addition to having a nucleus, animal cells also contain other membrane-bound organelles, or tiny cellular structures, that carry out specific functions necessary for normal cellular operation

Answer: the plant cell has a cell wall, chloroplasts, plastids, and central vacuole structures not found in animal cells. Plant cells do not have lysosomes or centrosomes.

Answer:

4. Fluid (Flexible)

Explanation:

Plasma membranes must be very flexible in order to allow certain cells, such as red blood cells and white blood cells, to change shape as they pass through narrow capillaries. The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.

Answer:

Water, Sunlight, Soil, and Air

Explanation:

Abiotic factors are the non-living components of an ecosystem. These are physical factors, such as water, sunlight, soil, and air.

In contrast, biotic factors are the living components and include birds and plants.

The way the biotic and abiotic factors interact with one another forms the ecosystem. The biotic factors rely on the abiotic factors to sustain their life.

Answer:

The activity factor was modified. Ambulating indicates that the person is active. Even small activities require energy. So, people who can walk around and aren’t bedridden expend more calories than people who need to be on bedrest all day. Also, when the stress factor was changed to severe infection, the caloric requirement increased. This increase is probably because the immune system requires more energy to fight off the infection

Answer:

A) photosynthesis and respiration

Explanation:

Answer:

C.It accelerates the production of a second messenger.

Explanation:

Adenylyl cyclase is an enzyme that catalyzes the conversion of adenosine triphosphate (ATP) to cyclic adenosine monophosphate (cAMP), a second messenger that activates the protein kinase A (PK-A) protein by dissociation of its regulatory subunit from the catalytic subunit. The first step of the epinephrine signaling pathway consists of the hormone binding to the epinephrine receptor localized on the cell surface. This binding activates a G protein inside the cell, which in turn activates the adenylyl cyclase enzyme. Subsequently, adenylyl cyclase converts ATP molecules into cAMP molecules. Since cAMP transports the message of the epinephrine hormone within the cell this molecule (cAMP) is considered to be a second messenger. Finally, cAMP activates the PK-A enzyme which phosphorylates different proteins and thus triggers different biological processes.

Answer:

Option C

Explanation:

The answer to this question is option C or "the leaves." The major site of photosynthesis in a plant is where the chloroplasts are located because it contains chlorophyll which is where photosynthesis takes place, chloroplasts is in all the green parts of a plant stem, leaves, and even the branches but it takes place mainly in the leaves of a plant because there is more leaves then roots or branches.

Hi there!

Photosynthesis involves carbon dioxide (CO2) and water (H2O) as the reactants with glucose (C6H12O6) and oxygen (O2) as the products. We can write a basic chemical equation:

[tex]CO_{2} + H_{2} O - (light) -> C_{6} H_{12} O_{6} + O_{2}[/tex]

The equation has to be balanced, so the final equation for photosynthesis would be:

[tex]6CO_{2} + 6H_{2} O - (light) -> C_{6} H_{12} O_{6} + 6O_{2}[/tex]

The chemicals in correct order are:

[tex]CO_{2}\\H_{2}O\\ C_{6}H_{12}O_{6}\\ O_{2}[/tex]
