This table shows how the levels of classification have changed with each major scientist.
Which number belongs in the space labeled X?
A. 5
B. 7
C. 8
D. 10
Answer:
Woese increased the number of levels of Hierarchy from 7 to 10, therefore the answer is D. 10
Explanation:
Carl Woese classified the three domains of life so 10 belongs in the space labelled X.
Who was Carl Woese?Carl Richard Woese was a microbiologist and biophysicist from the United States.
Woese is best known for identifying the Archaea (a new category of life) in 1977 through the phylogenetic taxonomy of 16S ribosomal RNA, a technique he pioneered and which revolutionized microbiology.
In 1967, he also proposed the RNA world idea, though not under that name.
Woese was a professor of microbiology at the University of Illinois in Urbana–Champaign and held the Stanley O. Ikenberry Chair.
Woese classified the various living forms into three categories:
Eubacteria, Archaebacteria, and Eukaryotes.
The three-domain classification is also useful for determining the evolutionary relationships between organisms.
Hence, the correct answer is D i.e. 10

A. Stationary
B. Warm
C. Occluded
D. Cold
When a cold air mass replaces a warm air mass, it's called a Cold front (Option D).
What is a Cold front?A cold front is a limit between two masses of air (one mass that is cool and the other that is warm).
This cold front may be very unstable and thus may be associated with the presence of storms.
In mid-higher latitudes, cold fronts generally advance the Equator by pushing the warm air up.
In conclusion, when a cold air mass replaces a warm air mass, it's called a Cold front (Option D).

Perform a Punnett square cross to find out. *
(2 Points)
0%
25%
50%
75%
100%
Answer:
25 percent
Explanation:
The reason why it is is because of how when you draw the punnet square, you have to write B in the first top part, and b in the second top part. Then, you draw B in the top left corner side, and then b in the lower left corner. When you write the Bb's, BB, and bb, you get a 25% chance that the baby would have blue eyes.

Explanation:
The Gulf of Mexico dead zone that forms each summer at the mouth of the Mississippi River is caused largely by the input of agricultural fertilizers that stimulate phytoplankton blooms, which die, and are subsequently consumed through bacterial decomposition. Decomposition consumes oxygen, leading to very low dissolved oxygen levels and subsequent death or emigration (i.e. leaving the area) of fish and other marine life. Many scientists advocate creating wetlands (as well as restoring them) as a strategy to reduce the severity and extent of the dead zone. The idea is that the plants in the wetlands will remove these nutrients from the water (during growth) and prevent their washing into the river and the Gulf of Mexico. Would the use of created wetlands be considered biotechnology
Answer:
Yes; the use of created wetlands would be considered biotechnology.
Explanation:
The created wetlands will employ the use of scientific tools and techniques, which will largely modify the plants, animals, and microorganisms in the Gulf of Mexico's dead zone. Generally, it has been established that biotechnology allows farmers to grow more food with environmentally sustainable farming techniques, which also improve soil conservation.
Answer:
Yes, the use of created wetlands would be considered biotechnology.
Explanation:
Biotechnology uses biological systems and living organisms to develop and create different products. The new wetland that they create will be made with the usage of scientific tools and techniques in order to replicate an already existing biological system. It will have very modified plants, animals and other organisms in the Gulf of Mexico's dead zone.
I need help with a problem
Amylose is Select one: a. a long, straight glucose chain. b. branched glucose chains. c. a long, straight fatty acid chain. d. branched amino acid chains.
Answer: A long, straight glucose chain (a major constituent of starch)
Explanation: Starch is mostly amylose (straight chain glucose polymer) but has varying amounts of branched glucose chains (amylopectin).
Fatty acids are hydrocarbons with a carboxylic acid group (-COOH) attached, so they are hydrophobic (don't mix with water) at one end and hydrophilic (water soluble at the COOH end)
Simple carboxylic acids don't have a long enough hydrocarbon chain to have this characteristic, e.g. CH3COOH acetic acid
Typical fatty acids found in nature include stearic acid with an 18-carbon chain
CH3-(CH2)16-COOH

b. Salt marshes act as a buffer for storms.
C. Salt marshes support marine life found in estuaries.
d. All of the above
Answer: C

humans who perceived them as barren unproductive areas of little economic value. Direct wetland
filling, point source pollution, nonpoint source pollution, invasive species
coastal salt maarsh
All of the above are benefits of having a healthy salt marsh.Therefore, the correct option is D.
What is a salt marsh?A salt marsh is a type of coastal wetland that is characterized by the presence of salt-tolerant grasses and other plants.
Salt marshes provide essential habitat for juvenile fish, as they serve as a nursery ground for many commercially important species. Additionally, salt marshes act as a buffer for storms by absorbing wave energy and reducing the impacts of flooding and erosion on coastal communities.
Finally, salt marshes support a diverse array of marine life found in estuaries, including crabs, oysters, and other shellfish, which are significant food sources for many animals, including humans.Therefore, the correct option is D.

What is photosystem 1 and photosystem 2 and what do they do? What are the steps ?
P I and PII are proteic compounds present in the thylakoid membrane that contain about 300 chlorophyll molecules each.
Step IFirst of all light with a wavelength of 690nm is absorbed by P II. The light excites an electron that leads to the photolysis of water(H2O--->2H+ +2e- + 1/2O2). The two electrons released go into the electron transport chain. The second compound in electron transport chain is plastoquinone that is reduced when it accepts electrons then oxidised when it loses them to P I. The next two compounds are cytocromes that make hydrogen protons go inside the thylakoid when they recieve the electrons.(I will mention what happens to the H+ in the second step). The next compound in the electron transport chain is a compound that contains Fe and S. The electrons finally reach the last step: Reduction of NADP+ to NADPH+H+.
Step IIIn the second step is ATP synthesis. Hydrogen protons accumulate inside the thylakoid membrane. An electrochemical gradient is formed. The protons can leave the thylakoid according to this gradient through an enzyme.
When the protons flow through , it turns ADP into ATP.
To sumarize: the role of P II is O2 production through photolysis and ATP synthesis(indirectly) The role of P I is NADPH+H+ synthesis.
