How does the human immune system work

Answers

Answer 1

Answer:

The acquired immune system, with help from the innate system, produces cells (antibodies) to protect your body from a specific invader. These antibodies are developed by cells called B lymphocytes after the body has been exposed to the invader. The antibodies stay in your child's body.

Describe an example of how island biogeography principles were used to explain biodiversity changes in areas that were not specifically islands.

Answers

Answer:

How Biogeography Affects Biodiversity

Alfred Russel Wallace, Father of Biogeography

Figure 1: Alfred Russel Wallace, Father of Biogeography

Some places contain more species than others. For example, Antarctica has fewer species than a temperate deciduous forest, which in turn has fewer species a tropical rainforest. For over 150 years, researchers have sought to make sense of the gross and fine scale spatial patterns in biodiversity, and to elucidate both the proximate and ultimate causes for these patterns.

This article describes some of the major geographic patterns in species richness, and the processes and theories that are thought to account for these patterns. Much of this knowledge has emerged from the tremendous body of work from one scientist, Alfred Russel Wallace (Figure 1), widely regarded as the “Father of Biogeography.” Aside from co-originating the process of Natural Selection with Charles Darwin, Wallace spent extended periods studying the distribution and diversity of plants and animals in Amazonia and Southeast Asia in the mid 1800s. Many of the patterns and processes featured in this article were initially described by Wallace, and careful study of his work indicates that his ideas presaged many of the discoveries made by his numerous successors.

Many of the spatial patterns in biodiversity are overt, others are subtle and yet additional patterns remain undetected. While the existence of these patterns may be obvious — and changes in the environment that are paired with these patterns may also be obvious — the mechanisms that cause the differences in biodiversity along environmental gradients are under still the subject of scientific debate. Because large-scale patterns are the emergent result of complex interactions at many spatial and temporal scales, no single answer is likely to ever emerge, but with continued research our understanding of the processes shaping these patterns increases.

Historical Processes Affecting Biogeography

Darwin's finches of the Galapagos Islands are a classic example of adaptive radiation.

Figure 2: Darwin's finches of the Galapagos Islands are a classic example of adaptive radiation.

All species occurring in at a given place and time either arrived from another place or originated in that location from ancestral species. This fact applies to extinct species that were ancestors of all extant species. Species richness in a given location is the result of three factors — the rate of speciation, the rate of extinction, and the dispersal of species from other locations. In principle, if biogeographers could understand how the current and past environment has shaped these three factors, we would then obtain a comprehensive understanding of what generates all biogeographic patterns of species richness. However, numerous environmental and organismal parameters can drive these historical factors, in both complex and interacting fashions.

In living organisms the cell
cycle is closely regulated.
What do you think will
happen if cell division is not
controlled?

Answers

Answer:

Explanation:

Disruption of normal regulation of the cell cycle can lead to diseases such as cancer. When the cell cycle proceeds without control, cells can divide without order and accumulate genetic errors that can lead to a cancerous tumor

The cell life cycle is controlled meaning that:

The reproduction of the cell is controlled.

The cell has a "programated death" meaning that at some point, all normal cells die.

If there is a problem with these (uncontrolled reproduction or cells that just not die) a tumor will appear.

Where the tumor is just a mass of these cells that reproduce uncontrolled and that don't die naturally.

So the thing that happens if cell division is not controlled, is that a tumor will appear.

Which molecule supplies chlorophyll with electrons

Answers

In light reactions, a molecule of chlorophyll absorbs one photon of light, causing a chlorophyll electron to transfer to a higher energy level. The energized electrons from the chlorophyll molecules flow down a transportation chain to a compound called nicotinamide adenine dinucleotide phosphate or NADP.

▪▪▪Cutest Ghost▪▪▪

Water is the molecule that supplies chlorophyll with electrons.

What happens during photosynthesis?

Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose (sugar) and other carbohydrates. This process also produces oxygen as a byproduct.

During the process of photosynthesis, chlorophyll absorbs light energy, which is used to split water molecules into oxygen and hydrogen atoms. The hydrogen atoms are then used to generate ATP and NADPH, which are used to power the process of carbon fixation. The oxygen atoms are released as a byproduct of water splitting and become a part of the oxygen in the Earth's atmosphere.

Metamorphic rocks are common when two continental plates collide because There is a lot of stress when enormous slabs of crust push together Sediment buries rocks to increase pressure O Magma bodies are common because there is a lot of melting O All of these​

Answers

Answer: Metamorphic rock, estimated to be as old as 3.8 billion years, located near Isua at Qorqut Sound, Greenland.In the rock cycle, there are three different types of rocks: sedimentary, igneous, and metamorphic. Sedimentary and igneous rocks began as something other than rock. Sedimentary rocks were originally sediments, which were compacted under high pressure. Igneous rocks formed when liquid magma or lava—magma that has emerged onto the surface of the Earth—cooled and hardened. A metamorphic rock, on the other hand, began as a rock—either a sedimentary, igneous, or even a different sort of metamorphic rock. Then, due to various conditions within the Earth, the existing rock was changed into a new kind of metamorphic rock.

The conditions required to form a metamorphic rock are very specific. The existing rock must be exposed to high heat, high pressure, or to a hot, mineral-rich fluid. Usually, all three of these circumstances are met. These conditions are most often found either deep in Earth’s crust or at plate boundaries where tectonic plates collide. In order to create metamorphic rock, it is vital that the existing rock remain solid and not melt. If there is too much heat or pressure, the rock will melt and become magma. This will result in the formation of an igneous rock, not a metamorphic rock.

When methane (CH4) combines with oxygen (O2), carbon
dioxide (CO2) and water vapor (H20) are produced.
Which equation represents this chemical reaction?
O A. CO2 + CH4 + 2H20 + 202
OB. CO2 + 2H20 – 202 + CH4
OC. CH4 + 202 – CO2 + 2H20
OD. CH4 + 2H20 - 202 + CO2

Answers

Answer:

C. CH4 + 202 – CO2 + 2H20

Explanation:

CH4+O2-CO2+H20

The above equation represents combustion of methane to produce carbon-dioxide and water.

One carbon atom is present on the reactant side as well as on the product side. Four hydrogen atoms are present on the reactant side  and two hydrogen atoms on product side. In order to balance this equation, we would multiply water molecule by two. Now there are four atoms of oxygen in the product side but only two on reactant side, so we will multiply oxygen molecule by two on the reactant side. Now the equation is balanced.

The balanced chemical equation is:

CH4+202-CO2+2H2O

This equation obeys the law of conservation of mass as the mass of the reactants is same as that of the products.

Answer:

C. CH4 + 202 – CO2 + 2H20
