Name the two main compounds that are exhaled (breathed out) by humans as a result of Aerobic Cellular Respiration
Answer:
carbon dioxide and oxygen
Explanation:
Carbon dioxide is the waste product of cellular respiration that you breathe out each time you breathe. Blood picks up oxygen and releases carbon dioxide in the lungs. The opposite takes place in the cells where the blood releases oxygen and picks up carbon dioxide.

the amount of electrical energy that can be generated by a hydroelectric power plants depends upon
Answer:
The amount of electricity a hydropower plant produces depends on two factors: How Far the Water Falls. The farther the water falls, the more power it has. Generally, the distance that the water falls depends on the size of the dam.
Explanation:
The amount of electrical energy that can be generated by a hydroelectric power plant depends upon the following factors:
The actual flow rate of water. The height of the water that falls. What is a Hydroelectric power plant?A Hydroelectric power plant may be defined as a renewable source of energy that generates electricity through the utilization of water from dams or diversion structures. Such types of plants are mainly used to transform hydraulic potential energy into electrical energy from water.
The actual flow rate and height of the water from it is falling demonstrate the amount of generated electrical energy. If the amount of water is present in excess quantity with a huge rate of flow and more the height of water in the hydroelectric power plant, it reveals that the generated electricity must be high under such circumstances.
Therefore, the rate of flow and height of water overall reveals the amount of electrical energy that can be generated by a hydroelectric power plant.

Water can be formed from the synthesis reaction of hydrogen with oxygen:
2 H2 (g) + O2 (g) → 2 H2O (g)
The complete reaction of 5.12 Liters of O2 with excess hydrogen produces how many moles of H2O?
A) 10.24 moles H2O
B) 114.7 moles H2O
C) 0.457 moles H2O
D) 5.12 moles H2O
Answer:
Explanation:
[2ΔSf(H2O (g))] - [2ΔSf(H2 (g)) + 1ΔSf(O2 (g))]
[2(188.72)] - [2(130.59) + 1(205.03)] = -88.77 J/
g It was noted in the Experimental Pathways feature in Section 10.4 that at least two- thirds of the human genome is derived from transposable elements. The actual number could be much higher, but it is impossible to make a determination about the origin of many other sequences. Why do you suppose it is difficult to make assignments about the origin of many of the sequences in the human genome
Answer:
TEs are repetitive and mobile elements, thereby it is hard to trace their origins
Explanation:
Repetitive elements are patterns of nucleotide sequences in the DNA characterized to have multiple copies throughout the genome. DNA mini-satellite and Transposable Elements (TEs) are some examples of highly repetitive DNA. TEs are repetitive mobile elements that have the ability to jump within the genome and occupy a major part of eukaryotic genomes. For instance, there is a type of TEs called retrotransposons which mobilize through a copy-and-paste mechanism, thus increasing their number in a genome. In consequence, TEs represent highly repetitive and dynamic genomic sequences, and thereby it is hard to trace their evolutionary histories.

Answer:
when cells break down food molecules, some of the energy on the molecules is released as heat. Cells use much of the remaining energy to make ATP. When glucose is broken down during cellular respiration energy is stored temporarily in molecules of ATP.
Explanation:
Identify three immune system organs and their functions.
Answer:
Primary lymphoid organs: These organs include the bone marrow and the thymus. They create special immune system cells called lymphocytes.
Secondary lymphoid organs: These organs include the lymph nodes, the spleen, the tonsils, and certain tissue in various mucous membrane layers in the body (for instance in the bowel). It is in these organs where the cells of the immune system do their actual job of fighting off germs and foreign substances.
Also...
Bone marrow is a sponge-like tissue found inside the bones. That is where most immune system cells are produced and then also multiply. These cells move to other organs and tissues through the blood. At birth, many bones contain red bone marrow, which actively creates immune system cells. Over the course of our life, more and more red bone marrow turns into fatty tissue. In adulthood, only a few of our bones still contain red bone marrow, including the ribs, breastbone, and pelvis.

what observations can be made and what can be concluded from these observations
Answer:
Correct option is A0 Based on the dispersion of white light into its constituent colours, we can conclude that (a) the white light consists of seven colours
Correct option isA0Based on the dispersion of white light into its constituent colours, we can conclude that (a) the white light consists of seven colours(b) the violet light suffers maximum deviation and the red light suffers minimum deviation.
Based on observations from dispersion, it can be concluded that white light is composed of seven colours of light.
What is dispersion of light?Dispersion of light is the separation of white light onto its constituent color as it passes through a refraction prism.
White Light consists of seven colours of varying wavelength.
When light is passed through a refracting prisms, dues the difference in the speed of the different constituents of light, seven colours of light are produced.
Therefore, based on observations from dispersion, it can be concluded that white light is composed of seven colours of light.

A brown guinea pig mates with a white guinea pig. All of the babies have tan, or light brown fur. The hair color trait in guinea pigs is probably ____.
1. Sex linked
2. Recessive
3. Incomplete dominance
4. Codominant
Answer:
It would be sex linked.
Explanation:
As you know (if you do), when two animals mate, they combine their genes to make a baby. So of their skin colors are different like one is brown and one is white, then you get a baby that would look brownish white or have spots that are brown or white.

Ecological Succession: Transformation of Communities over Time
Why does secondary succession occur faster than primary succession?
Answer:
Because there is already presence of soil and nutrients in secondary succession
Explanation:
Ecological succession, which is the series of gradual change that occurs in a community over time, can be of two forms namely: primary succession and secondary succession.
- Primary succession is a kind of succession that occurs in a barren land where no form of life has existed before while secondary succession occurs on a land that has been previously colonized by certain organisms called PIONEER SPECIES, and hence, a substrate containing nutrients called SOIL for growth is available during secondary succession.
This accounts for the reason the secondary succession is faster than the primary succession because there is already presence of soil and nutrients in secondary succession.
Answer:
Soil with nutrients is already present. Seeds are present from earlier occupants, brought in by wind, and/or germinate after fire.

In Drosophila, red eyes is wild-type and purple eyes are mutant. Full-size wings are wild-type and vestigial wings are mutant. Flies with wild-type pr pr vg vg genotypes were crossed with double mutant flies with a pr-pr- vg-vg- genotypes. The F1 flies had pr pr- vg vg- genotypes. The F1 flies with heterozygous genotypes were crossed with double mutant flies with a pr-pr- vg-vg- genotypes One thousand offspring were typed. This cross produced 430 red-eye, wild-type wing flies, 65 purple-eye wild-type wing flies, 60 red-eye, vestigial wing flies, and 445 purple-eye, vestigial wing flies. What is the distance between the loci for purple eyes and vestigial wings in centiMorgans (map units)
