<span>The answer should be 67.5gram
If Mary wants to consume 15% of her kcalories from protein, then the target calorie would be: 15% * </span><span>1800 kcal= 270kcal.
Every gram of protein will give about 4 kcal of energy. So, the protein needed in gram would be: 270kcal / (4kcal/gram)= 67.5 gram</span>
DDT stands for dichloro-diphenyl-trichloroethane. The first kind of synthetic/artificial insecticides came into use in the 1940s. The earlier usage of DDT include: a) Killing of malarial vectors, b) Combatting Typhus and other insect borne human diseases, c) As a pest control in crops d) as a pest control in garden, live stock production and even at homes.
The negative impact of DDT could be felt for the first time when the pests that were earlier killed by use of DDT have now become pesticides resistant. In the 1950s in USA, the regulatory measures were adopted to reduce the usage of DDTs as its effects as a pesticides were no more long significant and also it was creating detrimental physical and psychological impacts on the human and environment.
It was in 1972 that the U.S. Environmental Protection Agency cancelled the order for banning the usage of DDT based on the adverse impact it produced on the environment, human and other life forms. Since then continuous studies are being conducted to analyse the impact of DDTs. In some later years it was established that DDT is the cause of producing tumors in liver.
Some of the common negative impacts produced by DDT as per the U.S. Department of Agriculture :
a) The non destructive nature – DDT can not be destroyed and thus it remains persistent in the atmosphere
b) It attacks the tissues of living organisms especially the animals and humans ( fatty tissue)
c) It can penetrate the atmosphere to deeper extent.
Now as per the current stuation, The use of DDT is controlled and other alternatives of pest control organisms is being deduced. As per the treaty of Stockholm Convention on POPs (Persistent organic pollutants) , usage of DDT for malarial control is justified but it puts a restrictive use of DDT as pesticides in other areas.
Answer:
This is the remaining incomplete part of the question.
Requires separation of template strand Uses helicase Occurs during interphase of cell cycle Require primers Occurs in nucleus Requires dNTPs Produces Okazaki fragments Requires DNA polymerase Requires Primase Requires Taq DNA polymerase Requires cycles of heating Occurs in cytoplasm Occurs during anaphase of mitosis

Requires Primase Require primers
Requires DNA polymerase Requires Taq DNA polymerase
Occurs during interphase of cell cycle
Occurs in nucleus Occurs in test tube
Produces Okazaki fragments
A Cuticle, because a cuticle is waxy and it repels water and covers outside of a plant. Unlike a seed, phloem, ad xylem. If you think about your nails wouldn't you think cuticle as well?
Rock A = It is a metamorphic rock that experienced tremendous heat and pressure due to massive, moving tectonic plates.
Metamorphic rocks are rocks that have been somewhat squished and transformed by heat and pressure. These rocks often have different layers as the rocks go through pressure and are literally look like rocks that have been piled up and then stuck together. The best indicator of this rock being a metamorphic rock is the wavy elongated stripes. The stripes are created from the different rock elements being pressed together over time.
Rock B = It is a sedimentary rock made primarily from lithification of organic material.
Sedimentary rocks are rocks that have been formed by different substances that come together due to the different weather conditions. The best indicator of this being a sedimentary rock is how the rock came together and looks like a bunch of shells were glued together.
Rock C = It is an igneous rock that was formed above Earth’s surface.
Most igneous rocks have smooth outer layers. These rocks are often made with solidified magma from volcanoes. The best indicator of this being an igneous rock is the indication of it being a solidified piece of magma.
