Answer:
Option D = 3.4 g/mL
Explanation:
Given data:
Volume of water = 21.2 mL
Volume of water + object = 27.8 mL
Mass of object = 22.4 g
Density of object = ?
Solution:
First of all we will calculate the volume of object.
Volume of object = Volume of water+ object - volume of water
Volume of object = 27.8 mL - 21.2 mL
Volume of object = 6.6 mL
Density of object:
d = m/v
d = 22.4 g/ 6.6 mL
d = 3.4 g/mL

The human body processes and eliminates food waste using the organs of the excretory system. Which organelle performs a similar function in humans at the cellular level?
Answer:
Lysosome
Explanation:
The lysosome is a part of the endomembrane system. It is a series of sacs containing digestive enzymes that are surrounded by membranes. Lysosomes are produced by the Golgi apparatus. They break down waste products so some components can be released outside the cell and others can be recycled.

The amount of carbon on this Earth does not change. However, where the carbon is located does change. These locations are referred to as sources and sinks. Sources are areas that add carbon to the atmosphere and sinks are areas that remove carbon from the atmosphere. The sources and the sinks are important to the regulation of green house gasses. Carbon dioxide is one of several green house gasses that keep our planet warm. Too few greenhouse gases in the atmosphere would allow our planet to freeze, too many cause our planet to warm up too much. In the space below describe how humans are disrupting the natural cycle and contributing to the green house gasses in the atmosphere.
Answers
Answer:
In this stylized representation of the human-intensified greenhouse effect, human activities, predominantly the burning of fossil fuels (coal, oil, and gas), are increasing levels of carbon dioxide and other heat-trapping gases, increasing the natural greenhouse effect and thus Earth’s temperature.
Explanation:
One problem that was brought about by human action and is definitely affecting the hydrosphere globally is that of the greenhouse gases (so called because of their heat-trapping “greenhouse” properties) emitted to the atmosphere. Of the greenhouse gases released by anthropogenic activities, carbon dioxide has received much attention.

what are 3 modifications to pyruvate in the intermediate phase
Answers
Answer:
Simplified diagram of pyruvate oxidation. Pyruvate—three carbons—is converted to acetyl CoA, a two-carbon molecule attached to coenzyme A. A molecule of coenzyme A is a necessary reactant for this reaction, which releases a molecule of carbon dioxide and reduces a NAD+ to NADH.
Simplified diagram of pyruvate oxidation. Pyruvate—three carbons—is converted to acetyl CoA, a two-carbon molecule attached to coenzyme A. A molecule of coenzyme A is a necessary reactant for this reaction, which releases a molecule of carbon dioxide and reduces a NAD+ to NADH.
In eukaryotes, this step takes place in the matrix, the innermost compartment of mitochondria. In prokaryotes, it happens in the cytoplasm. Overall, pyruvate oxidation converts pyruvate—a three-carbon molecule—into acetyl two-carbon molecule attached to Coenzyme A—producing an t, N, A, D, H, end text and releasing one carbon dioxide molecule in the process. Acetyl C, o, A, end text acts as fuel for the citric acid cycle in the next stage of cellular respiration.
Pyruvate oxidation steps
Pyruvate is produced by glycolysis in the cytoplasm, but pyruvate oxidation takes place in the mitochondrial matrix (in eukaryotes). So, before the chemical reactions can begin, pyruvate must enter the mitochondrion, crossing its inner membrane and arriving at the matrix.
In the matrix, pyruvate is modified in a series of steps:
More detailed diagram of the mechanism of pyruvate oxidation.
1. A carboxyl group is removed from pyruvate and released as carbon dioxide.
2. The two-carbon molecule from the first step is oxidized, and NAD+ accepts the electrons to form NADH.
3. The oxidized two-carbon molecule, an acetyl group, is attached to Coenzyme A to form acetyl CoA.

The two-carbon molecule from the first step is oxidized, and NAD+ accepts the electrons to form NADH.
The oxidized two-carbon molecule, an acetyl group, is attached to Coenzyme A to form acetyl CoA.
Image credit: "Oxidation of pyruvate and the citric acid cycle: Figure 1" by OpenStax College, Biology, CC BY 3.0
Step 1. A carboxyl group is snipped off of pyruvate and released as a molecule of carbon dioxide, leaving behind a two-carbon molecule.
Step 2. The two-carbon molecule from step 1 is oxidized, and the electrons lost in the oxidation are picked up 2 \text{NADH}NADHstart text, N, A, D, H, end text are generated from \text{NAD}^+NAD
Step 3. The oxidized two-carbon molecule—an acetyl group, highlighted in green—is attached to Coenzyme A (\text{CoA}CoAstart text, C, o, A, end text), an organic molecule derived from vitamin B5, to form acetyl \text{CoA}CoAstart text, C, o, A, end text. Acetyl \text{CoA}CoAstart text, C, o, A, end text is sometimes called a carrier molecule, and its job here is to carry the acetyl group to the citric acid cycle.
The steps above are carried out by a large enzyme complex called the pyruvate dehydrogenase complex, which consists of three interconnected enzymes and includes over 60 subunits. At a couple of stages, the reaction intermediates actually form covalent bonds to the enzyme complex—or, more specifically, to its cofactors. The pyruvate dehydrogenase complex is an important target for regulation, as it controls the amount of acetyl \text{CoA}CoAstart text, C, o, A, end text fed into the citric acid cycle^{1,2,3}

Why make acetyl \text{CoA}CoAstart text, C, o, A, end text? Acetyl \text{CoA}CoAstart text, C, o, A, end text serves as fuel for the citric acid cycle in the next stage of cellular respiration. The addition of \text{CoA}CoAstart text, C, o, A, end text helps activate the acetyl group, preparing it to undergo the necessary reactions to enter the citric acid cycle.

2. Humans clear land for farming: Secondary succession.
3. A lake dries up, forming a marsh: Secondary succession.
4. A wind storm builds new sand dunes: primary succession.
What are main differences between primary and secondary succession?
Primary succession happens in a region without any initial verdure. Secondary succession occurs in a region with initial verdure. Primary succession is started either due to a biological factor or an outer agent. An external factor initiates secondary succession.
Thus, these are the answer.
