In another experiment, the leu gene was found to be located 5 minutes from the pro gene. In which location(s) in the gene map could the leu gene be located? (Note that the distances depicted between the genes on the map are not to scale.)

Mosquitoes and Housefly are grouped under the phylum Arthropoda because they both posses jointed legs (or appendages).

Animals that have jointed appendages are called Arthropods (i.e animals with jointed legs). They are triploblastic (i.e they have 3 germ layers) and exhibit bilateral symmetry. They are both six-legged arthropods sub-grouped under the class Hexapoda (coined from the word "hexa" meaning six and "Poda" meaning leg). Their body are divided into three parts; head, thorax and abdomen.

Answer:

The correct answer is: a. True.

Explanation:

There are several membrane transport systems responsible for the passage of ions like Na+ and K+.

Cell membranes are semipermeable, which means they can regulate which molecules may and cannot flow through them. Some molecules may simply drift in and out of a cell (this is called simple diffusion), while others require specific structures to enter and exit (this type of diffusion is called facilitated diffusion), and still, others require an energy boost to pass the cell membrane (this is known as active transport).

Both simple diffusion and facilitated diffusion are types of passive transport: they happen without the energy boost that ATP gives, unlike active transport.

In passive transport, molecules follow their chemical gradients and travel through the most concentrated compartment to the less concentrated one to equal the concentrations. In active transport, on the other hand, the cell makes an effort to enter or exit ions against their chemical gradients and this is done particularly to maintain said gradients (they are required for the correct functioning of the cell).

Sodium and Potassium are two of the most important ions when it comes to maintaining these gradients: sodium is very concentrated in the outside of the cells (the extracellular compartment), while potassium is highly concentrated in the intracellular compartment. These differences in concentrations are maintained thanks to the Na+/K+ pump, a form of active transport. Apart from the Na+/K+ pump, these ions go through the membrane through passive transport as well, without requiring energy.

Answer:

Low vitamin E levels may result in Muscle weakness: for the central nervous system, vitamin E is vital. It is one of the major antioxidants in the body and a shortage causes oxidative stress that can lead to weakening in muscles.

Explanation:

The body needs to work with vitamin E and become a necessary vitamin. It is fat-soluble, thus it has to be effectively absorbed in fat from the food. Before being released to the bloodstream for usage, vitamin E is mostly kept in the liver.

The deficiency is unusual and usually caused by an understatement. There are also modest levels of preterm newborns.

Eight kinds of vitamins exist. A blood test allows a physician to know how much a person has of an alpha-tocopherol form. Use this information to establish if the total vitamin E level of a person is present.

A standard level is typically between 5.5 and 17 milligrams (mg/L) per litre. For premature infants and youngsters under 17 years, the typical range may be different. The Normal scope may also be somewhat different amongst laboratories.

If an adult has less than 4 mg/L of vitamin E in his or her blood, supplementation is usually necessary.

Vitamins and minerals are considered essential nutrients—because acting in concert, they perform hundreds of roles in the body. They help shore up bones, heal wounds, and bolster your immune system. They also convert food into energy, and repair cellular damage.

Answer:

A to produce ATP as you are subconsciously producing ATP and you can not control it

Explanation:

To find food, to reproduce, and to avoid predators all are the functions of behavior except the production of ATP. Thus, the correct option is A.

Behavior is the range of actions and manners which are made by individuals, systems or artificial entities in a given environment. This can include other systems or organisms as well as inanimate physical environment.

The four main functions of behavior of an organism are attention, escape, access, and sensory needs. These four functions allow us to understand and categorize someone's actions, as well as determine the behavior of organisms such as finding food, reproduction, and avoiding the predators.

Therefore, the correct option is A.

Answer:

b. silencing marks like H3K9 methylation; activating marks like H3K9 acetylation

Explanation:

Genomic imprinting is an epigenetic phenomenon that leads to parent-of-origin-specific monoallelic expression, thereby genes under imprinting are differentially expressed depending on their parental origin. Genomic imprinting involves DNA methylation, histone modification such as histone 3 lysine 9 methylation (H3K9) and non-coding RNA regulatory epigenetic pathways, which act together to silence one parental gene form or 'parental allele'. Maternal imprinting occurs when the maternal allele is silenced (usually caused by methylation of the maternal allele), whereas paternal imprinting occurs when the paternal allele is silenced (methylation of the paternal allele). Moreover, H3K9 acetylation is connected with active promoters (gene transcription). The imprinted genes are generally grouped in genomic regions called imprinting centers (ICs) that regulate gene expression according to the parental origin.

Answer:

1) CO₂

2) 0.2551 g

Explanation:

The balanced reactions are:

CaCO₃ + 2HCl → CaCl₂ + H₂O + CO₂

MgCO₃ + 2HCl → MgCl₂ + H₂O + CO₂

1) The gas produced is CO₂.

2) Calculate mass of CaCO₃:

(0.5236 g) (0.4230) = 0.2215 g CaCO₃

Convert to moles:

(0.2215 g CaCO₃) (1 mol / 100.1 g) = 0.002213 mol CaCO₃

Find moles of CaCO₃:

(0.002213 mol CaCO₃) (1 mol CO₂ / mol CaCO₃) = 0.002213 mol CO₂

Convert to mass:

(0.002213 mol CO₂) (44.01 g / mol) = 0.09738 g CO₂

Calculate mass of MgCO₃:

(0.5236 g) (0.5770) = 0.3021 g MgCO₃

Convert to moles:

(0.3021 g MgCO₃) (1 mol / 84.31 g) = 0.003583 mol MgCO₃

Find moles of MgCO₃:

(0.003583 mol MgCO₃) (1 mol CO₂ / mol MgCO₃) = 0.003583 mol CO₂

Convert to mass:

(0.003583 mol CO₂) (44.01 g / mol) = 0.1577 g CO₂

Total mass of CO₂:

0.09738 g CO₂ + 0.1577 g CO₂ = 0.2551 g CO₂

The CRISPR-Cas9 genome editing system can be used to edit genes and correct mutations associated with inherited diseases. However, this technology also has the potential to edit genes in germline cells in order to irreversibly modify the human species and the natural evolution of life

Explanation:

The CRISPR-Cas9 (Clustered regularly interspaced short palindromic repeats and CRISPR-associated protein 9) system is a natural prokaryotic defense system used by bacteria to defend against invading DNA. In the laboratory, the CRISPR-Cas9 system has been repurposed to create a versatile genome-editing tool that allows us to modify the genome of mammalian cells in a targeted fashion. The CRISPR-Cas9 is a simple gene-editing tool that consists of a single guide RNA (sgRNA) that guides the Cas9 enzyme to the exact genomic location where Cas9 needs to make a cut, which is then repaired by different DNA repair mechanisms. During DNA repair, nucleotides can be replaced and/or deleted, thereby producing desired genomic modifications. The CRISPR-Cas9 has an enormous potential to repair mutations in genes associated with inherited genetic disorders and cancer (i.e., oncogenes might be reversed in vivo by using this technology). However, the CRISPR-Cas9 genome editing system is also a subject of concern due to its dual use. For example, this technology can be used to modify the genome of germline cells by inducing mutations that can be passed across generations, thereby irreversibly modifying human DNA and altering the normal course of evolution.

Answer:

The bag will get smaller

Explanation:

Osmosis can be defined as the process of diffusion or movement of water molecules across a semipermeable membrane from an area of higher concentration of water (i.e., lower concentration solution) to a lower concentration of water. For example, in cells, there are specialized pores called 'aquaporins' which are membrane proteins that form channels to transport water molecules by facilitated diffusion. In this case, the outside of the bag has a higher salt concentration than inside, thereby water molecules will move by facilitated diffusion through pores from inside to outside the bag.
