Answer: The particles that can pass through the cell membrane are the GREEN SOLVENT PARTICLES.

Explanation:

OSMOSIS can be defined as the thermal movement of solvent (water molecules) through a selectively permeable or semi-permeable membrane from a region of high concentration of the solvent to one where they are in low concentration.

The cell is bound by a membrane called plasma membrane. This membrane is selectively permeable and allows water and certain dissolved solvents to pass through it. As a result, the plasma membrane of the cell regulates the movement of materials between the cell and it's environment.

From the osmosis gizmo, it portrays a typical example of osmotic reaction occuring between a cell immersed in a solution of purple solute particles dissolved in green solvent particles. In order to maintain an osmotic balance between the cell and the solution surrounding it, the solvent (which is the green solvent particles) will move from the region of higher concentration to a lower region through the cell membrane

Answer:

Both deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are composed of nucleotides. A nucleotide is composed of three smaller molecules; a five-carbon, a phosphate group, and a nitrogenous base.

A DNA nucleotide contains the five-carbon sugar deoxyribose, a phosphate group, and one of four nitrogenous bases; adenine (A), guanine (G), cytosine (C), and thymine (T).

RNA  contains the five-carbon sugar ribose, a phosphate group, and one of four nitrogenous bases; adenine (A), guanine (G), cytosine (C), and uracil (U). Uracil takes the place of thymine (T).

Both thymine and uracil pair with adenine.

So DNA and RNA nucleotides differ according to which five-carbon sugar is present, and whether the nitrogenous base thymine or uracil is present. DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. DNA contains the nitrogenous base thymine, while RNA contains the nitrogenous base uracil.

Explanation:

Answer: Okazaki fragments are short sequences of DNA nucleotides (approximately 150 to 200 base pairs long in eukaryotes) which are synthesized discontinuously and later linked together by the enzyme DNA ligase to create the lagging strand during DNA replication.

Answer:

The correct answer is - C. oxidation of substances organic.

Explanation:

The major function of the mitochondria is to perform cellular respiration and produce energy in the form of ATP by oxidating organic molecules. All the process requires energy to be processed, however, the main and primary process that would disturb if by the destruction of the mitochondria occur which is the oxidation of glucose to convert it to pyruvic acid to generate energy.

The Krebs cycle that takes place in mitochondria and performs oxidation of organic molecules will also be disturbed and there will be no energy for any process.

Answer:

Of the 23 pairs of chromosomes in any normal human cell, the first 22 pairs provide directions for an individual's body and brain development. Scientists now estimate that about half of a person's personality traits and cognitive abilities can be traced to genetic influence and that psychological disorders arise from the interactions of many genes.

Explanation:

Chromosomes are small molecules that have the ability to carry all the genetic information needed to form a living being. These chromosomes are donated by an individual's parents and are used to form 23 pairs that determine all the internal and external characteristics of an organism. Among these 23 pairs, one pair will be responsible for determining the individual's gender, and the other 22 pairs will be responsible for the instructions that will make up the entire body and brain of the individual. Many scientists believe that chromosomes are responsible for even a part of a person's personality traits and that the genes they carry are directly related to the existence of psychological disorders.

The correct fillers for the given statements are: "22" and "personality and cognitive abilities"

Chromosomes are thread-like minute structures found in the nucleus of the plant and animal cells. These are the structures that help in transferring genetic information from one generation to another. Half chromosomes come from the mother and half come from the father's reproductive cells.

Thus, the correct answers are : "22" and "personality and cognitive abilities"

Answer:

The correct answer is - a) biochemical separation, identification, and quantification of mixture components.

Explanation:

Most hemoglobin disorders can be diagnosed by molecular diagnostic techniques such as protein-based techniques like electrophoresis and chromatography. Protein-based methods can diagnose early thalassemia disorders and hemoglobinopathies but in the case of α-thalassemia may be masked in the presence of β-thalassemia.

Molecular genetic testing plays a very important role in the biochemical separation of molecules or components, identification, and quantification of individuals carrying thalassemia and hemoglobinopathies traits and other hemoglobin disorders.

Answer:

carbon dioxide is more soluble in water than oxygen and hence is mostly transported in the dissolved form in our blood.

Carbon dioxide can be transported through the blood via three methods. It is dissolved directly in the blood, bound to plasma proteins or hemoglobin, or converted into bicarbonate.

The majority of carbon dioxide is transported as part of the bicarbonate system.

Answer:

D

Explanation:

Pollutants tend to an increase in concentration in the fatty tissues of animals compared to the concentration of the same pollutant in the environment.

Also, tend to increase in the fatty tissues of organisms at each trophic level.

Hence, as a result of this, the highest concentration of the insecticide is accumulated by the organisms at the highest level of the food chain. So, the tertiary consumers accumulate the highest concentration of the insecticide.

Answer:

- These morphological features belong to Down syndrome.

- Diagnosis: Down syndrome (Trisomy Extra chromosome 21).

- Etiology: the presence of three copies of the autosomal chromosome 21 instead of two copies in body (somatic) cells.

- Most important health problem: Down syndrome increases the risk of developing Alzheimer's disease (other health problems include heart congenital defects, vision problems, hearing loss, hypothyroidism)

- Diagnostic test: Amniocentesis

Explanation:

Down syndrome (DS) is the most frequent chromosomal abnormality which is generally caused by the presence of an extra copy of autosomal chromosome 21, thereby it is an autosomal trisomy (trisomy 21). DS is often associated with intellectual disability and increased risk of developing Alzheimer's, as well as health problems including, among others, heart congenital defects, vision problems, hypothyroidism, blood disorders, hypotonia, endocrine problems, dental problems, seizures, etc. Amniocentesis is the most common invasive prenatal diagnostic procedure which is used to identify chromosomal abnormalities such as trisomy 21 (Down syndrome). Amniocentesis is done between 15 weeks and 20 weeks of pregnancy.

Answer:

An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are sometimes called producers.Organisms are characterized into two broad categories based upon how they obtain their energy and nutrients: autotrophs and heterotrophs. Autotrophs are known as producers because they are able to make their own food from raw materials and energy. Examples include plants, algae, and some types of bacteria.
