The theory of plate tectonics states that the Earth's solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere, the molten upper portion of the mantle. Oceanic and continental plates come together, spread apart, and interact at boundaries all over the planet. It was proposed by Alfred Wegener.

4. The top part A of the flask-shaped reproductive organ X in the flower of a plant secretes a surgery substance
into its lower part B which goes towards the bottom part of the flask-shaped organ. When a tiny grain D
coming from the top part E of another reproductive organ Y in the flower falls on part A, it grows a long
tube F through the organ X in response to the sugary substance and reaches the bottom part C of flask-

Sometimes after an intense exercise routine, an individual will have sore muscles 1 to 2 days following the exercise; this is called delayed onset muscle soreness. Although not completely understood, it is believed that one cause of this is damage that occurs to the Z disks and contractile filaments in the muscles. When the body attempts to repair this damage, an inflammatory response occurs that causes soreness a couple of days after the exercise has taken place. Which of these situations would likely lead to less delayed onset muscle soreness in an individual?

a. a mutation in the Z-disk protein that caused the attachment of the Z disk to the titin protein to be stronger
b. a mutation that would reduce the amount of lactic acid buildup in muscle tissue
c. a mutation in the Z-disk protein that caused the attachment of the Z disk to the titin protein to be weaker
d. a mutation that weakens the calcium binding ability of troponin

Answers

Answer:

The correct answer is option A. a mutation in the Z-disk protein that caused the attachment of the Z disk to the titin protein to be stronger

Explanation:

As delayed onset muscle soreness is thought to be led by the inflammatory response of the body in order to repair damage to the Z disks and contractile filaments in muscles, due to the intense exercise.

Mutation in the Z-disk protein would strengthen the connection between Z disks and contractile filaments as it is logical that this mutation could withstand more pressure or intense exercise before damage occurs to these tissues.

Answer:

Proteins store energy long term, provide lubrication, and insulate the body

Explanation:

Proteins store energy long term, provide lubrication, and insulate the body  - this is false, this describes the role of fats. Proteins in the form of enzymes catalyze chemical reactions  - this is true, enzymes are an important class of proteins in the bodyProteins provide structures in the body, such as hair and muscles  - this is true, for example our hair is made of a protein called keratin Proteins in the cell membrane help transport substances into and out of cells  - this is true, proteins form important pumps and channels in the cell membrane

What is the difference between a niche and a habitat?

Answers

the role a species plays in the ecosystem is called its niche. A habitat is the physical environment in which a species lives.

A local ecosystem includes a variety of grasses that grow on spongy soil. In spring, heavy rainfall and melted snow cover the soil in a few inches
of water. The ecosystem dries up by late summer. What term BEST describes this ecosystem?
A. pond
B. estuary
C. wetland
D. stream bed

Answers

Answer:

The correct answer is C. Wetland.

Explanation:

A wetland is a generic name for habitats located between hard ground and open water. Wetlands include, for example, wet and waterlogged shallow land, shallow lakes and seas, marshes, floodplain forests, and flowing waters.

Wetlands provide a breeding ground for many animal and plant species and can act as a buffer in flood areas and prevent severe and sudden floods. Rainfall, waters entering the catchment area, soil and ground elevation differences in the area, and water evaporation form the hydrological conditions of the wetlands. Wetlands are one of the most valuable and endangered habitats on Earth. Swamps, overgrown lakes, flood-prone areas, shallow bays, water-covered beach areas and mangrove beaches are all endangered habitats.

If bacteria do not contain a nucleus will bacteria still have DNA?

Answers

Of course not the DNA is found in two basic forms: a chromosomal loop and ring-like plasmids. The chromosomal loop is literally a looping string of DNA. Since there is no true nucleus in a prokaryotic cell, the DNA is suspended in cytoplasm, or the fluid filling the cell.

what satellites are used to study expanses of the oceans surface

Answers

Answer:

The Geostationary Operational Environmental Satellite-16 (GOES-16) is the first of NOAA's next generation of geostationary weather satellites. Among the many missions of this satellite, it will collect ocean and climate data.

Explanation:

Using satellites, NOAA researchers closely study the ocean. Information gathered by satellites can tell us about ocean bathymetry, sea surface temperature, ocean color, coral reefs, and sea and lake ice. Scientists also use data collection systems on satellites to relay signals from transmitters on the ground to researchers in the field—used in applications such as measuring tidal heights and the migration of whales. Transmitters on satellites also relay position information from emergency beacons to help save lives when people are in distress on boats, airplanes, or in remote areas.

What are the roles of different organelles in a cell?

Answers

Answer:

Functions of different cell organelles:

Nucleus: contains all the genetic material, acts as information center and tells all the organelles what to do, RNA transcription.

Mitochondria: generates energy through respiration

Endoplasmic recticulum (rough): transport and storage of material; (smooth ER): creation of lipids and fats

Ribosome: protein creation by RNA translation  

Golgi apparatus: responsible for synthesis, packing and processing of proteins

Chloroplast: responsible for glucose creation (by photosynthesis)

Cytoplasm: is region where all chemical reactions take place  and is the jelly like fluid that holds all the organelles in place inside of the cell

lysosome: responsible for breakdown of larger molecules

Flagellum (or flagella): tail like organelle, assists motion

Vacuole: helps in maintenance of homeostasis  and stores waste products or other materials like water / food

cell membrane: separates cell from the rest of the environment  and controls what comes in and out of the cell

cytoskeleton: supports cell structure
