High levels of salt (Na Cl-) can disrupt the tertiary structure of proteins. What effect do you think increasing concentrations of salt would have on lactase activity
Answers
Increasing concentrations of salt would disrupt lactase activity by disrupting its tertiary structure. This enzyme breaks down lactose.
What is an enzyme?An enzyme is a protein that acts to lower the activation energy of a given chemical reaction.
Lactase is an enzyme that acts to break down lactose (a disaccharide) into galactose and glucose.
Different conditions in the media (in this case, concentrations of salt) may disrupt enzyme activity by altering its tertiary 3D structure.

The photograph shows rockweed. Which feature allows rockweed to
withstand the constant wave action of its environment?
A. The ability to carry out chemosynthesis
B. The ability to firmly attach to rocks
C. The ability to produce its own light
D. The ability to carry out photosynthesis
Answers
Answer:
B
Explanation:
This is the answer because if the rockweed is able to firmly attach its self to the rocks it would be able to withstand the constant wave action
The tendency to firmly attach to rocks allows rockweed to withstand the constant wave action of its environment.
RockweedIt is a brown alga and grows in the rich intertidal zone.
The holdfast of a rockweed permits it to withstand the constant wave action of its surroundings.
Holdfast is a tiny stem-like composition which allows the weed to anchor firmly to the rocks.
The rockweeds possess some of the advantages over the normal weeds that permits them to sustain in water like the intense developed root systems.
Thus, the correct answer is option B, that is, the ability to firmly attach to rocks.

Which are the four major groups of human pathogens?
A. bacteria, Viruses, Fungi and Protists
B. Protists, insects, bacteria and viruses
C. Fungi, Protists, Toxins and Bacteria
D. Viruses, Fungi, Protists and Toxins
Answers
Bacteria, Viruses, Fungi and Protists are the four major groups of human pathogens. Therefore, option (A) is correct.
What are human pathogens?Bacteria are microorganisms that are made up of a single cell and can be the source of illnesses such as strep throat, TB, and infections of the urinary system. The common cold, influenza, and COVID-19 are all illnesses that can be caused by viruses, which are non-living particles that can only multiply inside of a living host cell.
Infections such as ringworm, athlete's foot, and thrush can be caused by fungi, which are multicellular organisms that can spread from person to person. Protists are single-celled organisms that are capable of causing a variety of diseases, including giardiasis, malaria, and amoebic dysentery.
Insects and toxins, despite the fact that they are capable of inflicting harm on humans as well, are not considered to be major classes of human pathogens.

e following question
eous rocks are formed?
Answers
Igneous rocks contain randomly arranged interlocking crystals. The size of the crystals depends on how quickly the molten magma solidified: magma that cools slowly will form an igneous rock with large crystals. lava that cools quickly will form an igneous rock with small crystals. their visual appearance shows individual crystals interlocked together to form the rock mass. The cooling of magma deep in the Earth is typically much slower than the cooling process at the surface, so larger crystals can grow. Intrusive igneous rocks form in magma chambers that are deep underground. Many kilometers below the Earth's surface, molten rock called magma flows into cracks or underground chambers. There, the magma sits, cooling very slowly over thousands to millions of years. An intrusion is a body of igneous (created under intense heat) rock that has crystallized from molten magma. Gravity influences the placement of igneous rocks because it acts on the density differences between the magma and the surrounding wall rocks (country or local rocks). The most common river rocks used in landscaping and decorative construction are made of granite. Granite belongs to the "intrusive" category of igneous rock, which means it formed below the earth's surface as magma slowly cooled and crystallized. The rocks that form Earth's crust are continually destroyed and remade in an endless process called the rock cycle. Rock is formed by melting; by cooling and solidifying; by changing through heat and pressure; by weathering and erosion; and by compression and cementation.

Answers
Answer:
The researcher centred on the potential uses of biochar, charcoal primarily used for agricultural and to improve the quality of post mining sites.
A method called mountaintop removal was used by mining firms. This means that they remove rock and mineral deposits off the top of the mountain to gain access to within the coal seams. The resulting soil is infertile and strongly acidic. The compacted soil after mine proves harder to bring seed into the soil.
The researchers try to use biochar to help reforest the soil at the post-mining site. Before it was reseeded and replanted, they got permission to add a layer of biochar to a post-mining site. the team created “planting cells” of biochar‐enhanced soil on the post‐mining site and that showed improvment in the sapling growth.
