Answer:

A genetic disorder is a disease that is caused by the change in the sequence of DNA. Down Syndrom and Huntington disease are two examples of genetic disorders.

Explanation:

A genetic disorder is a change in the sequence of the DNA that results in a disease or condition. These disorders are caused by the mutation of one or multiple genes, by damage in chromosomes, or by environmental factors.

Down syndrome is a known genetic disorder where there is an extra copy of chromosome 21 instead of the two copies. People with Down Syndrom have intellectual difficulties and a different physical complexion that can lead to some problems.

Huntington disease is a genetic disorder that causes the degeneration of neurons, which brings emotional, cognitive, and movement problems that worsen with time since it is a progressive disease.

Answer: carbohydrates

Explanation:

Lactose is a disaccharide and it is an example of a carbohydrate. So the correct option is A.

A disaccharide can also simply be called a double sugar. It is that type of sugar that is formed when two monosaccharide molecules or simple sugars are combined by the formation of a glycosidic linkage. Disaccharides are soluble in water, like monosaccharides. Sucrose, lactose, and maltose are commonly known disaccharides.

The carbohydrates, which on acid or enzyme hydrolysis, release two molecules of monosaccharides which are either of the same type or different are called disaccharides.

The loss of the water molecule results in the formation of an oxide linkage and after that, the two monosaccharides are formed by that linkage. The joining of two monosaccharide units via an oxygen atom results in the formation of a glycosidic linkage.

Sucrose is the most common disaccharide which gives D -(+)- glucose and D-(-)- fructose on hydrolysis.

Therefore the correct option is A.

Answer:

1. The correct option is B: Isoelectric focusing

2. The correct option is A: At a pH of 6.0

Explanation:

1. Gel electrophoresis is a technique used to separate proteins on the basis of size. Since these two proteins are of similar size (or molecular weight), it will prove to be ineffective to achieve the desired result.

2. Since valine has an uncharged side chain, it will not be affected by pH value so it needs to be maintained at the value where it does not exert direct influence on the protein with histidine.

Answer: The thoracic cavity contains the heart, lungs and many of the main vessels of the circulatory system. It is found anterior to the vertebral cavity.

Explanation:

The thoracic cavity is the second largest hollow space of the body and it is the space limited by the ribs, the vertebral column, and the sternum. It is the upper region of the body starting from the neck and ending where the diaphragm ends. So, it is separated from the abdominal cavity by the diaphragm. It contains 12 ribs, and 7 of them attach directly to the sternum, 3 attach to the sternum via cartilages and 2 do not attach to the sternum at all and are called floating ribs. The cavity contains several organs, such as the lungs, heart, great vessels and esophagus.

The abdominal cavity spaces around the organs are filled with the core muscles that attach to the posterior spine. Besides. the ribs vertically, horizontally and across the abdominal region.

The vertebral cavity is the posterior portion of the dorsal cavity, it contains the spinal cord within the vertebral column, the meninges and the fluid-filled spaces between them. It is formed by the vertebrae through which the spinal cord passes.

The thoracic cavity is anterior to the vertebral cavity, because anterior describes the front or direction toward the front of the body.

Answer:the third one I guess

Explanation:

The rate of photosynthesis can slow down due to low water pressure in vacuoles and without water, the mitochondria cannot convert carbon dioxide to glucose during photosynthesis. So the correct option is C. The ribosomes are directly involved with the translation of mRNA to form proteins.

Green plants and certain other creatures convert light into chemical energy through a process called photosynthesis. Light energy is gathered and utilized during photosynthesis in green plants to change the water, carbon dioxide, plus minerals into oxygen- and energy-rich organic molecules.

It is hard to overstate the role that photosynthesis plays in sustaining life on Earth. There would eventually be little food or other organic materials on Earth if photosynthesis stopped. The majority of life would vanish, and eventually, the atmosphere of Earth would contain almost no gaseous oxygen. Only chemosynthetic bacteria, which can use the chemical energy of certain inorganic substances and are not reliant on the conversion of light energy, would be able to survive in such an environment.

The fossil fuels (coal, oil, and gas) that drive modern society today were created by plants using energy from photosynthesis carried out millions of years ago. Green plants and tiny critters that fed on plants grew more rapidly in the past than they were eaten, and as a result, sedimentation as well as other geological processes buried their remnants in the Earth's crust.

Therefore, the correct option is C.

Answer:

C. Oxygen

Explanation:

Mitochondria are membrane-bound organelles found in the eukaryotic cells. They are regarded as the "power house" of a cell because of the vital role they play in the synthesis of energy needed to drive an organism's cellular activities. Their role in production of energy (in form of ATP) comes from the cellular respiration that occurs in them.

The kreb's cycle and oxidative phosphorylation of aerobic cellular respiration occurs in the mitochondria. As the name "aerobic" implies, oxygen is strictly involved in the process of respiration occuring in the mitochondria. Hence, if researcher removes all of the mitochondria from a cell, the cell will be unable to use OXYGEN, which is necessary for the cellular respiration in the mitochondria.

The main difference between a natural resource and an ecosystem service is that natural resources are tangible and can be directly used by humans, while ecosystem services are intangible and are the benefits that humans get from ecosystems.

Natural resources are often used to provide ecosystem services. For example, water is a natural resource that is used to provide the ecosystem service of regulating temperature.

Ecosystem services are essential for human well-being. They provide us with food, water, shelter, and other essential resources. They also help to regulate our climate, clean our air and water, and provide us with a place to recreate.

Answer:

Explanation: A water molecule, because of its shape, is a polar molecule. That is, it has one side that is positively charged and one side that is negatively charged. The molecule is made up of two hydrogen atoms and one oxygen atom. The bonds between the atoms are called covalent bonds, because the atoms share electrons. The hydrogen atoms have one electron each.

Because they share those electrons with the oxygen atom, the electrons tend to stay close to the oxygen atom and the outside of the hydrogen atom tends to be positively charged. The oxygen atom has eight electrons. Most of those tend to stay away from the hydrogen atoms, and cause the outside of the oxygen atom to have a negative charge.

Answer: It has one side that is positively charged and one side that's negatively charged.
