What experiment led directly to Dalton's atomic theory?
Answer:
Dalton's experiments on gases led to his discovery that the total pressure of a mixture of gases amounted to the sum of the partial pressures that each individual gas exerted while occupying the same space. In 1803 this scientific principle officially came to be known as Dalton's Law of Partial Pressures.

17. Animal cell do not have chloroplasts. Why not?
Answer:
Animals don't need chloroplasts because they acquire sugar from their diet; they just need mitochondria. Vacuoles are found in both plant and animal cells. A big, solitary vacuole is found in each plant cell and is used to store water and nutrients.

what is the functions of lipid?
The main biological functions of lipids include storing energy, as lipids may be broken down to yield large amounts of energy. Lipids also form the structural components of cell membranes, and form various messengers and signaling molecules within the body.
Answer:
function as energy storehouses, and function as important signaling molecules.
This three main types of lipids are triacylglycerols (also called triglycerides), phospholipids, and sterols.
Explain how water makes its way to the leaves in the tops of the tallest trees against the force of gravity. Name what the climbing of water is called and the two other properties that are responsible for making this possible.
Answer: Capillary action occurs because water is sticky, thanks to the forces of cohesion (water molecules like to stay close together) and adhesion (water molecules are attracted and stick to other substances).

How is a dolphin fin similar to a dogs leg
Answer:
Dogs and dolphins have a lot in common. Even though these animals may be from different species, and live in entirely different environments, they do share one commonality: they're friendly and curious. Both dogs and dolphins will be the first to investigate a new person or situation
Explanation:
The dolphin fin is similar to a dog's leg in the following ways: Both are used for movement.
What are the use of dolphin's fins?The dolphin fin helps the dolphin to swim and navigate in water, while the dog's leg is used for walking and running. Both are composed of bone and muscle. The dolphin fin has a skeletal structure made up of bones and muscles, which allow it to move in different directions. The dog's leg also has a skeletal structure made up of bones and muscles, which allow it to support the dog's weight and move in different directions.
Both are adapted to their respective environments. The dolphin's fin is shaped to help it move quickly and efficiently through water. The dog's leg is adapted to help it run and navigate on land. Both have joints. The dolphin fin has a joint where it connects to the body, which allows it to move in different directions. The dog's leg has joints that allow it to bend and move in different directions.

Regions that have similar climate characteristics can be widely spread apart, but typically have which of the following in common?
Varying altitudes and similar precipitation
Corresponding latitudes and continental locations
Corresponding temperature and wind patterns
Similar ocean currents and vegetation
Answer:
B.) Corresponding latitudes and continental locations
Explanation:
I got it right on the test :)
The regions that have similar climate characteristics can be widely spread apart, but typically have corresponding latitudes and continental locations (Option B).
The amount of precipitation and solar radiation largely determine the climatic conditions of a given region.Regions that have similar climate characteristics are found in similar latitudes to receive a similar amount of solar radiation.Moreover, these regions also are found in similar continental locations because it affects the amount of precipitation.In conclusion, regions that have similar climate characteristics can be widely spread apart, but typically have corresponding latitudes and continental locations (Option B).

Answer:
This approach is a technique used to appraise the environmental impact associated with all stages of a product's life. (from raw material extraction through materials processing, manufacture, distribution, use, repair and maintenance, and disposal-recycling).
Explanation:
Everything that is produced goes through these five main stages:
1.) material extraction
2.) manufacturing
3.) packaging
4.) transportation
5.) use and end of life
At each of these stages, there are inputs and outputs, flow-throughs, value losses, and potential gains.
Put the steps of HIV cellular infection and replication in the correct order:
- The T helper cell is killed.
- New HIV virion is assembled.
- New HIV buds off the T helper cell getting it's envelope while the Protease enzyme matures the new virus.
- The Integrase enzyme integrates the viral genome with the T helper cell's genome.
- Uncoating of the capsid.
- Reverse Transcriptase turns the ssRNA genome into ds DNA.
- Merging of viral envelope with the T helper cell membrane.
- The T helper cell copies the HIV genome and makes HIV proteins.
- Attachment of the gp proteins in the HIV envelope to CD4 on the T helper cell.
holy person produces antibodies to packages that invade the body. But with the infection of H. I V, the body was, is the ability to produce antibodies and how is that possible? Um, and it shows that the matter said Axe and destroys CD for he cells, which help Erkki South. So we have determined the function of this and how we can affect, as we see in this of antibody production. So basically, the helper peace. So is the middleman in turned immune response. So we have an antigen presenting cell that presents an androgen that activates Alberti sell. The activation of that T cell releases side of kinds that activate B cells. Activation of B cells triggers proliferation of plasma cells, which Ruiz antibodies and thus is able to fight the whatever pathogen has entered the body. But if the virus directly kills off helper T cells, then there's no way for the immune system to actually launch a defense against HIV or any other pathogen. Because the cells and T cells, which carry out cell mediated and Hugh Meral immune responses, are not able to be activated and carried out. So let's see which answer best matches that a cease the CD 40 sells a record intermediate are required intermediate in a series of salty cell signal events that must be completed before B cells. Commager. Yes, that is true. As depicted by this diagram. Let's see if there's any other true statements he states the city for T cells have CD four molecules Cove in when we bound to their source cell surfaces and do not induce apoptosis and other cells during an immune response. So, really, we have nothing to the inducing a pop doses really has nothing to do with, uh, the question. It also does not see the forties city for T cells do not induce apoptosis. So that is just a false statement. Um, and it's just not relevant to the question. See, states That CD for T cell counts are about 1000 per micro liter and a healthy person, but drop over 400 per micro liter. So once again, this is not relevant to how C D four T cells and the loss of them, uh, contribute to the loss of any body synthesis. And D says that CD four cell precursors air formed in the bone marrow and then migrate to the thymus where they developed their T cell receptors. So once again, not relevant. So we can see that B, C and D are just irrelevant to the question of antibody synthesis and the connection to CD four C T cells, which, uh, the correct answer to is a

Protein promotes metabolic reactions, supports tissue growth and repair, and synchronizes biological processes. Proteins give your body a structural foundation while also ensuring optimal pH and fluid balance. Thus option B, C, D is correct.
What is function of protein?Amino acids make up proteins. These substances aid in transforming T cells, B cells, and antibodies—important immune system components—into germ-fighters that recognize and eliminate potentially infectious cells as they enter your body.
Amino acid chains are the building blocks of proteins, which fold into distinctive three-dimensional structures.
The final folded shapes of proteins are well-suited for their tasks, and the bonds inside protein molecules assist to stabilize their structure.
An enzyme is a biological catalyst that speeds up a chemical reaction without changing its equilibrium, according to a short and straightforward definition.
Therefore, protein perform a wide variety of functions in a cell.
