describe how the ancestors of whales moved from the land to the sea.
Answer:
To swim, they move their tails up and down, rather than back and forth as fishes do. This is because whales evolved from walking land mammals whose backbones did not naturally bend side to side, but up and down.

1.
Helium
Hydrogen
Nitrogen
2.
Hydrogen
Lithium
Helium
3.
Copper
Silver
Iron
Answer:
1: hydrogen
2: helium
3: iron
Explanation:
In medium-sized stars such as the Sun, nuclear fusion almost always means the fusing of hydrogen nuclei to form helium, but larger stars can produce elements as heavy as iron. The correct options are B, C, and C.
What is Nuclear fusion?The primary distinction between these two processes is that fission is the splitting of an atom into two or more smaller ones whereas fusion is the fusing of two or more smaller atoms into a larger one.
In nature, fission reactions are uncommon. Many highly radioactive particles are created during fission.
The Sun and other stars are powered by nuclear fusion reactions. In a fusion reaction, two light nuclei fuse to form a single heavy nucleus. The process releases energy because the overall mass of the resulting single nucleus is less than the mass of the two initial nuclei.
Therefore, the correct options for 1, 2, and 3 are B, C, and C, respectively.

There are several different types of cells in our body including bone, cartilage, blood, muscle, and nerve cells. Regardless of the type of cell they all have the same ___ [ Select ] ___ but different ___ [ Select ] ___
Answer:
This question is incomplete
Explanation:
This question is incomplete and hence makes it difficult to be accurate because of the absence of options. However, for the first blank space, what human cells have in common (with each other in the same body) is the genetic composition thus it can be said that regardless of the the type of cells, almost all of them have the same DNA or genes. However, presence of the same DNA does not mean they carry out the same function. This is as a result of a process known as differentiation.

Are tyere any mammalian cells that would be a good source for dividing cells?
Answer:
Explanation:
This question appear wrong. Cells do not divide other cells as cells have the ability to undergo individual cell division as seen in cell cycle. However, there are some factors that could lead to increased cell division; factors such as cancer and viral infection can lead to increased division of certain cell types.
There is also a cell organelle present in mammalian cells that facilitates the division of a cell - this organelle is known as centriole. Centrioles do this by assisting in the separation of chromosomes during the mitotic phase of the cell cycle.

What name is given to a factor which is preventing any increase in photosynthesis?
Answer: A limiting factor
Explanation: A limiting factor is simply anything in short supply that prevents photosynthesis occurring at its maximum rate. Three factors can limit the rate of photosynthesis: light intensity, carbon dioxide concentration and temperature.
Any factor that prevents any increase in photosynthesis is known as a LIMITING FACTOR.
In photosynthesis, a limiting factor is defined as a factor/agent that constrains photosynthetic activity.The most important factors capable of limiting the rate of photosynthesis include light, carbon dioxide (CO2) level and temperature.For example, photosynthesis cannot take place without light, which is absorbed by chlorophyll pigment molecules to start photosynthesis.In conclusion, any factor that prevents any increase in photosynthesis is known as a LIMITING FACTOR.

Which equation best represents conservation of matter? (1 point)
3H2O + 3CO2 → C6H12O6 + 602
6H2O + 6CO2 + C3H603 + 302
6H2O + 6CO2 → CH12O6 + 602
6H2O + 10CO2 → C5H12O6 + 402
i’m so sorry for asking so many questions!
Conservation of matter is the law that states the amount of matter involved and produced. The reaction, 6H₂O + 6CO₂ → C₆H₁₂O₆ + 6O₂ follows the law. Thus, option C is correct.
What is conservation of matter?Conservation of matter has been the law used in science that defines the amount or the mass of the matter to remain the same even after undergoing a chemical reaction where the reactant yield product.
In some cases, the matter seems to be lost but in reality, it is due to the change in the phase of matter. So, the mass in a system is a constant that is neither added nor removed.
The equation, 6H₂O + 6CO₂ → C₆H₁₂O₆ + 6O₂ best represents the law of conservation as there are 12 hydrogens, 6 carbon, and 18 oxygen on both sides of the reaction.
Therefore, option C. 6H₂O + 6CO₂ → C₆H₁₂O₆ + 6O₂ follows the law of conservation of mass.

Greenhouse gases are measured by their ability to trap outgoing solar radiation and convert it to heat, warming the atmosphere.
Global warming potential is defined as the ability of an atmospheric gas to contribute to increasing global temperatures and
anthropogenic climate change. Carbon dioxide is used as a baseline for global warming potential, with a GWP of 1. What best
explains why CFCs (chlorofluorocarbons) have a GWP
nearly 5000?
Answer:
Greenhouse gases, such as carbon dioxide, methane, nitrous oxide, and certain synthetic chemicals, trap some of the Earth's outgoing energy, thus retaining heat in the atmosphere. This heat trapping causes changes in the radiative balance of the Earth—the balance between energy received from the sun and emitted from Earth—that alter climate and weather patterns at global and regional scales.
Multiple lines of evidence confirm that human activities are the primary cause of the global warming of the past 50 years.1 Natural factors, such as variations in the sun's output, volcanic activity, the Earth's orbit, the carbon cycle, and others, also affect Earth's radiative balance. However, beginning in the late 1700s, the net global effect of human activities has been a continual increase in greenhouse gas concentrations.
This change in concentrations causes warming and is affecting various aspects of climate, including surface air and ocean temperatures, precipitation, and sea levels. Human health, agriculture, water resources, forests, wildlife, and coastal areas are all vulnerable to climate change.
Many greenhouse gases are extremely long-lived in the atmosphere, with some remaining airborne for tens to hundreds of years after being released. These long-lived greenhouse gases become globally mixed in the atmosphere and their concentrations reflect past and recent contributions from emissions sources worldwide. Others, like tropospheric ozone, have a relatively short lifetime in the atmosphere.

Lucy and Jim have been married for 5 years and have decided they would like to try to have a child. However, a rare genetic disorder runs in both or their families, so they decide to go to a genetic counselor to determine the chances that their future child will be affected. The disease achondrogenesis 1a affects the ability of proteins necessary for bone and cartilage development to be modified and packaged properly after leaving the endoplasmic reticulum. The results are devastating. Individuals with this disorder are often stillborn or die soon after birth from respiratory failure. Fortunately, after doing a genetic screening, the genetic counselor determined that while Jim is a carrier for this autosomal recessive disorder, Lucy is not. Therefore, if they do have a child it is unlikely that their child will be affected. Which organelle has been compromised
Answer:
The Golgi complex is compromised
Explanation:
The Golgi complex helps in the process of synthesis and packaging of proteins and lipids, especially those proteins that are for exportation. The organelle´s function is to manage the recently synthesized proteins, to transform them, and to export them to other places.
Different proteins are synthesized in the endoplasmic reticulum and sent to the Golgi complex in vesicles, where it happens the final association of carbohydrates with proteins. Finally, protein is transported from the Golgi complex to its final destiny. Proteins destined to a certain place are packaged all together in the same vesicle and sent to the target organ. In the case of membrane proteins, they are packaged in vesicles and sent to the cell membrane where they get incrusted.
By being affected by the achondrogenesis 1a, the Golgi complex loses its functions and is incapable of finishing the protein synthesis and transport process, affecting other cells and their functions.
