Answer:
Wetlands must have one or more of the following three attributes: 1) at least periodically, the land supports predominantly hydrophytes; 2) the substrate is predominantly undrained hydric soil; and 3) the substrate is saturated with water or covered by shallow water at some time during the growing season of each year.
Explanation:The minimum essential characteristics of a wetland are recurrent, sustained inundation or saturation at or near the surface and the presence of physical, chemical, and biological features reflective of recurrent, sustained inundation or saturation.

which type of microscopy allows us to clearly view the internal contents of cell structures smaller than 200 nm?
Because the cell structures are so small, to clearly view them, requires a microscope that has a higher power of magnification than light microscopes can prove. This is usually an Electron Microscope.
Electron microscopy (EM) is a technique used to obtain high-resolution images of biological and non-biological specimens. It is often used to investigate the detailed structure of tissues, cells, organelles, and macromolecular complexes. (UMass Chan Med School Website)

tumors can coerce the formation of blood vessels to serve the cancer cells within the tissue. what is this process called?
Answer:
Such tumors, unless they secrete hormones, cause few problems. However, most tumors induce the formation of new blood vessels that invade the tumor and nourish it, a process called angiogenesis.
Explanation:
How can you test the idea that solar energy is required for the reduction of NADP+ to NADPH?
Answer:
In addition to biology, evidence drawn from many different disciplines, including chemistry, geology, and mathematics, supports models of the origin of life on Earth. In order to determine when the first forms of life likely formed, the rate of radioactive decay can be used to determine the age of the oldest rocks (see optional problems C and D, below) exposed on Earth’s surface. These are found to be approximately 3.5 billion years old. The age of rocks can be correlated to fossils of the earliest forms of life. A. The graph compares times of divergence from the last common ancestor based on the fossil record with a "molecular time" constructed by comparing sequences of conserved proteins to determine a mutation rate (after Hedges and Kumar, Trends in Genetics, 2003). Explain how such a molecular clock could be refined to infer time or the evolution of prokaryotes. B. Using a molecular clock constructed from 32 conserved proteins, Hedges and colleagues (Battistuzzi et al., BMC Evol. Biol. 2004) estimated the times during which key biological processes evolved. A diagram based on their work is shown. Connect the time of the origin of life inferred from this diagram with the age of the oldest fossil stromatolites and the age of the oldest exposed rock to show how evidence from different scientific disciplines provides support for the concept of evolution. Evaluate the legitimacy of claims drawn from these different disciplines (biology, geology, and mathematics) regarding the origin of life on Earth. The oldest known rocks are exposed at three locations: Greenland, Australia, and Swaziland. The following application of mathematical methods provides essential evidence of the minimum age of Earth.

6. The thick rigid layer that surrounds plant cells and provides support and structure is called the:
(a) Nucleus
(b)Mitochondria
(c) Cell wall
(d)Chloroplast
Answer:
C. Cell wall
Explanation:
The cell wall gives the cell its structure and protection. It also provides support to the cell by making sure nothing happens to it, and it is considered the outer layer of the cell and the layer is very thick and rigid.
Help me I need this done by the end of the class if you are a bot you will get your answer kicked so stop
Answer:
1. In the natural carbon cycle, there are two main processes which occur: photosynthesis and metabolism. During photosynthesis, plants use carbon dioxide and produce oxygen. During metabolism oxygen is used and carbon dioxide is a product.
2. When fossil fuels are burned, they release carbon dioxide and other greenhouse gases, which in turn trap heat in our atmosphere, making them the primary contributors to global warming and climate change.
3. it Disrupts the nitrogen cycle by contaminating the groundwater and making it more difficult for the plants to absorb the nitrogen and causes the phosphorus cycle to accelerate, resulting in an excess of phosphorus in water and soil.
4. The phosphorous cycle is slower than carbon cycle and nitrogen cycle because phosphorous is found mainly in very small dust particles. It moves very slowly from the deposits on land and in sediments and then it is transferred to the organism and from organism it is moved more slowly to the soil.
¿Cuáles son las funciones vitales que realiza la célula y por qué son importantes?
Doy corono
Es la criatura viviente más simple que se conoce, lo que significa que es capaz de realizar las tres funciones vitales, que son la nutrición, la interacción y la reproducción. Consta de dos partes que son la membrana plasmática y el citoplasma.
Proporcionan estructura al cuerpo, ingieren nutrientes de los alimentos, convierten esos nutrientes en energía y realizan funciones especializadas. Las células también contienen el material hereditario del cuerpo y pueden hacer copias de sí mismas. Las celdas tienen muchas partes, cada una con una función diferente.

The normal body temperature of an adult human is between 36.1°C and 37.2°C. The normal body temperature of an adult chicken is between 40.6°C and 41.7°C. Based on this information, do you think most human enzymes and chicken enzymes have identical structures? Explain why or why not.
Answer:
Almost 60% of chicken genes correspond to a similar human gene. Although, researchers uncovered more small sequence differences between corresponding pairs of chicken and human genes, which are 75% identical on average, than between rodent and human gene pairs, which are 88% identical on average

what is the name used to refer to the clogged xylem tissue?
The name used to refer to the clogged xylem tissue is heartwood in contrast to sapwood, a term for the dead, clogged xylem cells near the center of a tree. Heartwood has been the tree as the main column of support.
What is xylem?Xylem has been defined as the vascular bundle which has been used to transport water and other minerals from the root part to other parts of the plant. The main function of the xylem and phloem is to transport water and minerals from root to other parts of the plant.
The last common ancestor of the gymnosperms and angiosperms possessed the same characters such as the pollen, seeds, and the vascular tissue.The gymnosperms are a group of plant that are known as seed- producing plants such as Ginkgo, gnetophytes, cycads etc.
Angiosperms has been the plant that produces flowers and having seeds enclosed within their fruit. Gymnosperms have no production of flowers and fruits and they contain bare seeds on the surface of their leaves.
Therefore, The name used to refer to the clogged xylem tissue is heartwood in contrast to sapwood, a term for the dead, clogged xylem cells near the center of a tree. Heartwood has been the tree as the main column of support.

how are the purposes of the digestive system and circulatory system linked?
Answer:
Explanation:
) Digestive System gets nutrients (good) from food and hands it over to the blood and Circulatory System then carries those nutrients where they need to go. (2) Filters out waste from food and pushes it through intestines and out the body (and you know how and where it gets out).

Answer:
Natural selection is a process where organisms that are better adapted to an environment will survive and reproduce. This means that the advantageous alleles of this variant organism are passed on to offspring. Over many generations, the process of natural selection leads to evolution occurring.

what is the difference between a joint and a fault?
Answer:
Fractures include joints and flaws. A joint is a fracture along which there has been no movement, which is generally generated by tensional pressures. A fault is a fracture or break in the rock that has allowed movement to occur. Near faults, more earthquakes are likely to occur.
