Researchers have been studying how emissions from both volcanoes and human activities, such as the burning of fossil fuels, impact the atmosphere. Both types of emissions contribute to the total CO2 levels in the atmosphere. Graph 2 shows that atmospheric CO2 levels have been steadily increasing over time. This increase in CO2 levels has been linked to the increase in global surface temperatures.Explain why the total mass of carbon must be decreasing in a different step of the slow carbon cycle based on the on the increase in atmospheric CO2.

How are invertebrates better? PLZ help ASAP

Answers

Invertebrate, any animal that lacks a vertebral column, or backbone, in contrast to the cartilaginous or bony vertebrates. More than 90 percent of all living animal species are invertebrates. Worldwide in distribution, they include animals as diverse as sea stars, sea urchins, earthworms, sponges, jellyfish, lobsters, crabs, insects, spiders, snails, clams, and squid. Invertebrates are especially important as agricultural pests, parasites, or agents for the transmission of parasitic infections to humans and other vertebrates. Invertebrates serve as food for humans and are key elements in food chains that support birds, fish, and many other vertebrate species.Apart from the absence of a vertebral column, invertebrates have little in common. Indeed, they are distributed between more than 35 phyla. In contrast, all vertebrates are contained within a single phylum, the Chordata. (Phylum Chordata also includes the sea squirts and some other invertebrate groups.) Invertebrates are generally soft-bodied animals that lack a rigid internal skeleton for the attachment of muscles but often possess a hard outer skeleton (as in most mollusks, crustaceans, and insects) that serves, as well, for body protection.

The ________ photosynthetic reactions convert light energy into chemical energy, which is stored in molecules like ATP. In the _________ photosynthetic reactions, this energy is used to convert CO2 into carbon sugars. A) light dependent; chloroplast
B) chloroplast; light independent
C) light dependent; light independent
D) light independent; light dependent

Answers

Answer:

Explanation:

light-dependent reactions require sunlight. In the light-dependent reactions, energy from sunlight is absorbed by chlorophyll and converted into stored chemical energy, in the form of the electron carrier molecule NADPH (nicotinamide adenine dinucleotide phosphate) and the energy currency molecule ATP (adenosine triphosphate). The light-dependent reactions take place in the thylakoid membranes in the granum (stack of thylakoids), within the chloroplast.

While In the light-independent reactions, the energized electrons from the light-dependent reactions provide the energy to form carbohydrates from carbon dioxide molecules. The light-independent reactions are sometimes called the Calvin cycle because of the cyclical nature of the process.

So the answer is definitely C

Answer:

Your answer would be C; Light dependent, light Independent

you are a molecule of carbon. choose a starting point in the carbon cycle and describe the process you would go through to move through the entire cycle

Answers

The carbon cycle is a natural way to recycle carbon in the environment. It usually starts with the atmosphere and ends by getting released into the atmosphere itself.

What are the steps of carbon cycle?

The carbon released into the atmosphere through either respiration, combustion of fossil fuels, vehicles, etc.

The main steps involved in carbon cycle are:

Carbon moves to plants through atmosphere.
From plants it goes to animals.
When plants and animals die, the carbon is then released to the soil.
Carbon also released from the fossil fuels on burning.
It also comes from oceans to the atmosphere.

Thus, it can be concluded that the molecule of carbon starts from atmosphere and ends by being released to the atmosphere.
