Answer:

Nucleic Acids are precursor for Proteins.

Explanation:

Proteins are formed( protein units called amino acids) by the decoding of specific nucleic acids to give specific Proteins.

No nucleic acids don't provide energy, these are building block of genetic material (DNA). While Proteins provide energy.

No proteins don't carry genetic information.

Yes structure of protein is determined by nucleic acids because each nucleic acids code fir specific unit of amino acid which join to form protein.

No subunits of nucleic acids are nucleotides where as subunits of Proteins are called amino acids.

The correct answer is option a: They have no mass. Photons are considered massless particles, which means they have zero rest mass.

Photons are elementary particles of light and electromagnetic radiation. They are the fundamental unit of light and are considered as massless particles that travel at the speed of light in a vacuum. Photons have both wave-like and particle-like properties and are quantized, meaning that they can exist only in discrete packets of energy called quanta. The energy of a photon is directly proportional to its frequency, according to the famous equation E=hf, where E is the energy of the photon, h is Planck's constant, and f is the frequency of the photon. Photons are important in many areas of physics, including quantum mechanics, electromagnetism, and thermodynamics.

Archaea  is a single-celled organism domain. These microbes are prokaryotes because they lack cell nuclei. Archaea were originally classed as bacteria and given the name archaebacteria (in the Archaebacteria kingdom), but this word is no longer used.

Archaeal cells differ from the other two domains, Bacteria and Eukaryota, in several ways. Archaea is further subdivided into many recognized phyla. Classification is challenging because most have not been isolated in a laboratory and have only been found in environmental samples by their gene sequences. It is uncertain if they are capable of producing endospores.

Rob is experiencing premature ejaculation, where he ejaculates seconds after penetration, causing strain in his relationships over the years. a form of sexual dysfunction. a) Rob is experiencing premature (early) ejaculation.

Rob is experiencing premature (early) ejaculation, which is a form of sexual dysfunction. Premature ejaculation is characterized by the inability to delay ejaculation during sexual activity, resulting in ejaculation occurring shortly after penetration or even before penetration.

This condition can lead to significant distress and strain on relationships, as described in Rob's case. Premature ejaculation can have various causes, including psychological factors such as anxiety, stress, or relationship issues, as well as physiological factors.

Treatment options for premature ejaculation may include behavioral techniques, such as the stop-start or squeeze technique, counseling or therapy, and in some cases, medications may be prescribed. It is important for Rob to consult with a healthcare professional to discuss his symptoms and explore appropriate treatment options for his condition.

Extractive reserves are Option A: community-managed protected areas designed to allow for sustainable extraction of certain natural resources (such as fish, rubber, brazil nuts, and rattan) while maintaining key ecosystems in place.

In Brazil, a sustainable use protected area is referred to as an extractive reserve. Although the area is publicly owned, the locals have the right to engage in customary extractive activities including hunting, fishing, and gathering wild flora. Law No. 9.985 of July 18, 2000 defines a variety of sustainable-use, protected areas, including "extractive reserves." The National System of Conservation Units was formed as a result (SNUC). The extractive reserves are public property, although traditional extractive populations—mostly indigenous—are permitted to use the area. These are locations that traditional extractive populations use to support their subsistence farming, small-scale livestock raising, and extraction-based economies.

The reserves are established to ensure sustainable resource usage as well as to save the way of life and culture of these peoples.

The feature that could help identify the fungus is the presence of chitinous cell walls.

All prokaryotes are single-cellular and some eukaryotes are also single cellular so if several single-cellular organisms are presented then by identifying the cell wall compositions we can find out from which group the organism belongs.

Fungi are different from bacteria and archaea. Bacteria have a cell wall made up of peptidoglycan, in the archaea cell wall is made up of pseudo-peptidoglycan.

Fungi's cell membrane is covered by a cell wall which is made up of chitin and they are eukaryotes. They can be multicellular or single-cellular. So chitinous cell wall is the distinguishing feature that helps identify the fungus.

Energy metabolism is the process of generating energy from the nutrients and this process is indispensable for cell homeostasis maintenance and responses to varying conditions. Cells require energy for the growth and maintenance and have evolved to have multiple pathways to generate energy.

Metabolism is the set of life-sustaining chemical reactions in the organisms. Three main functions of metabolism are as:  conversion of energy in food to energy available to run cellular processes; conversion of food to building blocks for proteins, lipids, nucleic acids and some carbohydrates and elimination of metabolic wastes.

Answer:

The answer is that the child will most likely look like half of one of the parent and the other half of the parent, like 50/50.

Explanation:

- The reason for this is each parent will pass only half of their gene to the child and the other half will either be from one of the parents or random (such as from their grandparents, parent's siblings, etc).

- However, sometimes other things can occur. For example, the child can look completely like one of their parents because that parent's genes are dominant.

For example, if you have parents, one with brown eyes, brown hair and the other one have blue eyes and blonde hair. There is a higher chance the child can come out looking like the parent with brown eyes and brown hair. The reason for this is blue eyes and blonde hair are recessive traits.

Explanation:

10x + y = 4(x + y)                         Remove the brackets

10x + y = 4x + 4y                         Subtract 4x from both sides

10x - 4x + y = 4x - 4x + 4y          Combine like terms

6x + y = 4y                                  Subtract y from both sides

6x + y - y = 4y - y                        Combine

6x = 3y                                        Divide by 3

6x/3 = 3y/3

2x = y

Put this result in the equation below

x*y = 8

x(2x) = 8

2x^2 = 8                                      Divide by 2

2x^2/2 = 8/2

x^2 = 4                                         Take the square root.

√x^2 = √4

x = ± 2

y = 2*x = ±4

Answer

The plus answer for x and y is the one we'll see about first.

10x + y = 20 + 4 = 24

24 =? 4(2 + 4)

24 =? 4*6 = 24

The product of it's digits = 2 * 4 = 8.

Explanation: Hydrogen bonds between the water molecules on the liquid surface are relatively strong and pull on each other more than air molecules. This bond strength results in surface tension that tends to minimize the liquid surface area and produce a spherical raindrop.

Precipitation is the one of the main processes in the water cycle. It involves the formation of clouds and transforming into either rain, snow, sleet, or hail. This is possible due to the property of cohesive ability of water molecules. Thus, the correct option is A.

Precipitation is one of the main processes involved in the water cycle. It is the liquid or frozen water which forms into the atmosphere and falls back to the Earth in the form of rain, sleet, snow, or hail. It comes in many different forms. Along with the evaporation and condensation of water, precipitation is one of the three major parts of the global water cycle.

Precipitation is achieved by the cohesive ability of the water molecules which explains the formation of clouds and rain drops. Cohesive forces are responsible for binding the compounds together such as a rain drop containing water molecules.

Therefore, the correct option is A.
