See the answer below

Explanation:

Zara should keep the clownfish and the goldfish in separate tanks - the goldfish in a freshwater tank and the clownfish in a salt water tank.

If the goldfish is kept in a salt water tank instead of freshwater, it may die due to dehydration because the salt water would be hypertonic to the cells of the fish. Water would move osmotically from the cells of the fish into the surrounding water and the fish may eventually die due to dehydration.

If the clownfish is kept in freshwater instead of salt water, it may die due to excessive water. The freshwater would be hypotonic to the cells of the fish and water would move osmotically from the surrounding water into the cells of the fish. Eventually, the cells would become turgid and may start lysing, leading to the death of the fish.

Answer: In recent times, reproductive biotechnologies have emerged and started to replace the conventional techniques. It is noteworthy that for sustained livestock productivity, it is imperative to start using these techniques for facing the increasing challenges for productivity, reproduction and health with impending environment conditions. These recent biotechniques, both in male and female, have revolutionized

Answer:

#1, #2, and #4 are correct. #3 is incorrect.

Answer:

This simply explain the concept of osmosis. A solution of 0.8% is lower in conc. (hypotonic)compare to that of 0..2%(hypertonic)Therefore, the inner cells layer would lose water to higher hypertonic concentrated medium.

      water flows from .8% to salt solution of 0.2%

This follows the concept of osmosis which is the movement of water molecule from the region of higher water potential(.08) to region of lower water potential(0.2) but high solute potential, through  a semiportable ,membrane, the plasma membrane.

Answer:

The cells specialized in passive diffusion have a greater amount of membrane structures called transport proteins.

Explanation:

Facilitated diffusion is a transmembrane transport mechanism, which consists of the passage of substances through the cell membrane by means of a transporter.This process does not require energy, as it is a passive transport, and depends on an ionic gradient or concentration.

The carriers of facilitated diffusion can be integral membrane proteins, so a cell specialized in this type of transport must have abundant transport proteins.

Answer:

Down syndrome, Turner syndrome and Klinefelter syndrome.

Explanation:

Down syndrome, Turner syndrome and Klinefelter syndrome are the genetic disorders which are found in chromosome. Down syndrome is a common genetic disorder that occurs when a person has three copies of 21st chromosome. It is also called  trisomy 21. Due to this disorder, delays occur in physical and mental developmental and disabilities of human body parts.

Answer:

1. Chromosome 11 is made of over 130 million base pairs.

2. Approximately how many genes are found on

chromosome 11? 2000

3. autism (neurexin 1), acute intermittent porphyria, albinism, ataxia-telangiectasia, Beckwith–Wiedemann syndrome, Best's disease, beta-ketothiolase deficiency, beta thalassemia.

4.Autism is related to some changes in chromosome 11, although it is characterized as a psychological disorder. It is usually identified in childhood, between 1 and a half years and 3 years, although the initial signs sometimes appear in the first months of life. The disorder affects the child's communication and ability to learn and adapt. Chromosome 11 Duplication Syndrome is a chromosomal alteration that interferes with child development, which may trigger motor, cognitive, language and socialization delays, inability to perform simple motor activities, weight and height deficit, facial dimorphisms and congenital malformations. Jacobsen's syndrome is an inherited disorder caused by the deletion of a specific region of the long arm of chromosome 11, which covers the 11q24.1 band. Patients with this disorder have a phenotype characterized by delayed neuropsychomotor development, craniofacial anomalies, diverse heart defects and blood dyscrasias. Signs and symptoms include: Heart defects; mental delay; difficulty feeding in childhood; attention deficit; hyperactivity; skeletal malformation, among others.

Answer:

Hurricane.

Explanation:

Hurricane and tornadoes are the catastrophic events that occur when the warm air from the gulf of Mexico and the cold air from the north combines together. These hurricanes and tornadoes causes a lot of damage and destruction if the speed and intensity are higher. These hurricanes produced in different region and causes destruction in another region due to its mobility.

3. Spiral.

Explanation:

In crime scene investigation, individuals who are certified professionals (investigators) in collecting evidence after an unfortunate incident such as murder has occurred use the following strategic investigative methods or techniques;

1. Line method: investigators move from one side of the crime scene to another in a single direction. This method is best used in areas that comprises of obstacles e.g rocks, trees, pillars etc.

2. Zone method: crime area is divided into multiple square areas and each is assigned to an investigator. This method is best used in buildings such as hospital, office, school etc., because these investigators are assigned to each zone of the divided crime area.

3. Spiral method: from the outside or the center of the crime scene, the investigator walks down a circular path and works their way inward or outward.

Answer:

Somatic cells

Explanation:

A somatic cell mutation in an organism is passed on to the daughter cells in an organism. But this type of mutation doesn't affect the future generations because only genes carried by sperm or ova can become part of offspring's gene material.

Answer: there will be 24 daughter cells I believe.

Explanation:

Explanation:

It is happening when a sodium atom loses an electron to a chlorine atom and because of that sodium atom is becoming a positive sodium ion and the sodium ions and chloride ions form an ionic lattice.

Sodium - Na

Chloride - Ch

Sodium and Chloride are both elements that cannot be found separately and free in nature but they are found as bonded together.

Answer:

Function of protein also temporarily changed.

Explanation:

If the structure of a specific organ protein is changed temporarily due to the local environment of protein, the function of the protein also changed temporarily because the structure of protein changed which does not allow suitable environment for the proper functioning of the protein so we can conclude that the function of the protein also temporarily changed.

Answer:

TRUE!! All prokaryotic organisms are unicellular.

Explanation:

Answer:

the last one is:

 In the process of meiosis, alleles separate and are added to the gametes in an independent manner. While each gamete (egg or sperm cell) therefore contains one allele for each gene, it's impossible to know which allele, because alleles segregate in a random manner. However, it's possible to calculate probabilities that the offspring will have a given allele using Punnett squares.

Explanation:

Crossing over process results in new combinations of alleles in the gametes (egg or sperm) formed, which ensures genomic variation in any offspring produced.

Chromosomal crossover, or crossing over, is the exchange of genetic material during sexual reproduction between two homologous chromosomes' non-sister chromatids that results in recombinant chromosomes.

This process, also known as crossing over, creates gametes that contain new combinations of genes, which helps maximize the genetic diversity of any offspring that result from the eventual union of two gametes during sexual reproduction.

Crossing over is an enzyme-mediated process, where the exchange of genetic material between non-sister chromatids of homologous chromosomes takes place.

Explanation:

Answer:

With increase of deer, there will be a decrease of producers.

Explanation:

Increasing of deer populations means decreasing of producers. As more and more deers are eating plants, the producer population will decrease. Thus, the producer population are in demand and deers will eventually need to fight for food with other deers–– this is known as competition, which is a biotic factor. An abiotic factor can be lack of oxygen once the producer population has been decreased due to the increase deer population.

Answer:

1. Concentration of O2 in the alveoli must be more than that of the blood

2. Concentration of CO2 in the blood must be more than that of the alveoli

3. Movement does not stop (find the explanation below).

Explanation:

Gaseous exchange i.e. taking in of O2 and taking out of CO2, takes place in the alveoli/air sac of the lungs. However, the movement in and out of O2 and CO2 from the alveoli into the bloodstream and vice versa follows the principles of SIMPLE DIFFUSION. Diffusion is the process whereby substances move from a region of high concentration to a region of low concentration until they are evenly distributed. Based on this, the following will occur:

1. The concentration of O2 in the alveoli must be more than that in the blood in order for oxygen to enter the blood via diffusion.

2. The concentration of CO2 in the blood must be more than that in the alveoli in order for carbon dioxide to leave the blood and enter the alveoli via diffusion.

3. When the rate of diffusion is at equilibrium i.e. no net movement is occuring die to equal concentration of the substance on both sides, the substances begin to move in the opposite direction at an equal rate. Note that, at equilibrium, MOVEMENT DOES NOT STOP, however, there is an equal rate of movement.
