Answer:
The correct answer would be an option B.
Asexual reproduction is a reproduction in which offspring are produced from a single parent.
It does not involve fusion of gametes and crossing over due to which the offspring contain identical genome as that of parents.
This reduces the genetic diversity in a population due to which all the organisms of a population are at equal risk of extinction under unfavorable conditions such as high temperature, antibiotics, change in pH of surrounding medium et cetera.
Thus, the disadvantage of asexual reproduction is the lack of genetic diversity due to which a single antibiotic is able to kill millions of genetically identical bacteria.
Answer:
Dinoflagellates are classified as members of the Protista Kingdom.
Explanation:
The responsible organisms, Dinoflagellates, are classified as members of the kingdom Protista. It is also considered an algal protist. When it grows uncontrollably it is called a "bloom". This bloom is not always harmful, but when it is, it can prove fatal to many other organisms in its food chain.
b. contains a KDEL sequence near its C-terminus.
c. has a membrane-spanning domain length equals the
d. thickness of the cis-Golgi membrane.
e. was imported directly into the cis-Golgi posttranslationally.
f. has a mannose-6-phosphate tag.
Answer:
C. has a membrane-spanning domain length equals the thickness of the cis-Golgi membrane.
Explanation:
Secretory pathway is the pathway that transport proteins to the cell surface membrane. For this, the membrane proteins are labeled radioactively and move through the various organelles to carry the proteins to the surface membrane.
After six hours, all the radioactivity is concentrated in the cis-Golgi apparatus this means that The protein carries membrane-spanning domain which widens or make the cis-Golgi menbrane thick.
Hence, the correct answer is "C".
B: Fossil fuels lead to global climate change.
C: The US imports much of its petroleum from foreign countries which set the prices.
D: All of the above.
The fossil fuel use in the United States makes the U.S. vulnerable to the political wishes of foreign countries because the US imports much of its petroleum from foreign countries which set the prices, i.e., option C.
Fossil fuels are came from the decomposition of plants and animals.
These fuels can be found in the Earth's crust and encompasses carbon and hydrogen which can be burned for energy. Fossil fuels entail coal, oil, and natural gas.
The fossil fuel use in the United States makes the U.S. vulnerable to the political wishes of foreigncountries because the US imports much of its petroleum from foreign countries which set the prices.
Thus, the correct option is C.

2)Which best describes the aquifers?
Aquifers 1 and 3 may result in a reduced river flow.
Aquifer 2 may result in reduced surface water levels.
Aquifers 2 and 3 may result in decreased wetland and spring discharge.
Aquifer 3 may result in an increase in productivity.
3)How can recycling materials lead to environmental sustainability?
a.
Recycling materials helps decrease the amount of new materials taken from the environment.
b.
Recycling materials helps increase the rate of carbon sequestration.
c.
By recycling materials, the amount of biomass available for energy purposes is increased.
d.
All of the above
1. The correct answer is B. Conservation tillage practices help the soil erosion and also maintains soil nutrient levels.
Conservation tillage is termed as the tillage system which helps to conserve energy, soil, water through retention of crop residue and reduction of tillage intensity.
2. Correct answer is A. Aquifers 1 and 3 may result in a reduced river flow. Aquifer is termed as the underground layer of rock fractures, water-bearing permeable rock.
Hydrogeology is termed as study of water flow which is found in aquifers.
3. Correct answer is A. Recycling materials helps decrease the amount of new material which are taken from environment.
Most household can be recycled. Some other examples which are recycled include textiles, plastics, organics, and metals. Metals such as drinking bottles and food cans which are made from steel and aluminium can be recycled.
B. Flowers
C. Seeds
D. Cones
