volcanic eruptions can affect climate by
Answers
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
Explanation:
A group of students wanted to know if millipedes prefer moist or dry environments. They suspected that millipedes would prefer moist environments because they had observed that millipedes are usually found under decaying logs.
Answers
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.

Describe how positive control in prokaryotes can be altered by the external environment
Answers
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.
Which of the following statements best describes the role of adenylyl cyclase in
the epinephrine signaling pathway?
A.It converts a polymer to its monomer subunits.
B.It moves substances across the plasma membrane.
ect!
C.It accelerates the production of a second messenger.
D.It transfers phosphate groups from to protein substrates.
Answers
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.
Referring to the image above, what are the abiotic factors in this image?
A
Water, Plants, and Birds
B
Birds and Plants
С
Soil, Plants, and Birds
D
Water, Sunlight, Soil, and Air
Answers
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.

What are the 3 main pros and 3 main cons of climate change ? and explain why they are a pros and a cons.
Answers
1. Trauma from floods
2. Droughts
3. Heat Waves
4. More heat = longer allergy seasons and more respiratory diseases.
The pros to climate change would include anything positive. Soooo
1. Fewer winter deaths
2. Low energy costs
3. Better agricultural yields
4. Fewer droughts.
Here is your conclusion.
Climate change may have a couple of pros but overall it’s terrible and we don’t want it to happen. It’s dangerous and could end the world. We need to take care of our earth and it’s as simple as not littering. Climate change is bad and just about every living thing would go extinct. Aka animals and humans.

Answers
Answer:
Option C

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.

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.

What would best describe the structure of the plasma membrane?
1.rigid (not flexible)
2.gaseous
3.solid
4.fluid (flexible)
Answers
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.
Do all living things obtain the matter and energy they need to live and grow in the same way?
Answers
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.
How do living things obtain energy?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.

What other factors did you modify for BEE? Why do you think you need to consider these factors with caloric intake?
Answers
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

Answers
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]
