The subatomic particle that is neutral is the Neutron. (An) electron is a negatively charged particle

According to modern atomic theory, the proton can't move from one energy level to another

With the work of the English chemist John Dalton, the current atomic theory, which has continuously undergone refining, started to blossom at the beginning of the 19th century.

The modern atomic theory holds that atoms are no longer indestructible and now contain electrons, protons, neutrons, and other sub-particles. Isotopes are variations of an element's atoms that can exist.

The concepts of atoms and how they create matter are established by current atomic theory. Atoms are composed of negatively charged electrons revolving around a core nucleus made up of electrically neutral neutrons and more massive positively charged protons.

High and low tides are primarily caused by the gravitational pull of the moon on the Earth and the rotating force of the Earth. The gravitational attraction of the sun and moon to the earth is what causes tides.

In mechanics, the force of attraction that acts on all matter is known as gravity, also known as gravitation. It has no impact on identifying the interior properties of common stuff because it is the weakest force known to exist in nature.

Two masses are drawn toward one another by the gravitational force. No matter how absurd it may seem, every subatomic particle of energy in the cosmos attracts every other particle through gravity.

Answer: false

Explanation: biotic factors are living things, these things listed are non-living things

Answer:

Enzymes rely on molecular movement and collisions with the compounds they are meant to bind with -- called substrates -- so they can speed up certain chemical reactions. Increases in temperature increase molecular activity, and can result in a higher rate of collisions between enzymes and substrates. If the temperature rises too high, however, the enzymes could become denatured, and the positive effects of the temperature increase could be nullified.

Explanation:

Many enzymes lose function at lower and higher temperatures. At higher temperatures, an enzyme's shape deteriorates. Only when the temperature comes back to normal does the enzyme regain its shape and normal activity unless the temperature was so high that it caused irreversible damage.

The main skeletal features used to construct a cladogram include the presence or absence of specific bones/structures, bone shape/structure, dental characteristics, skeletal adaptations, and skull morphology.

Cladograms are phylogenetic trees that illustrate the evolutionary relationships between different organisms. When constructing a cladogram, various skeletal features can be used as characters to determine the branching patterns and common ancestry among organisms. Here are some main skeletal features used in cladistic analysis:

Presence or absence of specific bones or structures: The presence or absence of certain skeletal elements, such as wings or limbs, can provide insights into evolutionary relationships.

Bone shape and structure: Comparing the shapes, sizes, and structures of bones can help identify shared characteristics and infer common ancestry.

Dental characteristics: The structure and arrangement of teeth, including the type and number of teeth, can provide information about evolutionary relationships and dietary adaptations.

Skeletal adaptations: Features like the presence of a notochord, presence of a bony skeleton, or modifications for specialized locomotion (e.g., wings, fins, limbs) can be used to infer evolutionary relationships.

Skull morphology: Examination of the skull, including the shape of the cranium, presence and structure of specific cranial bones, and jaw structure, can help determine evolutionary relationships and functional adaptations.

By analyzing these skeletal features and comparing them across different organisms, cladistic analysis aims to identify shared derived characteristics (synapomorphies) that indicate common ancestry and to construct a branching pattern that represents the evolutionary relationships between the organisms being studied.

Explanation:

The statement which is true about the single gonadal tissue cell with 6 picograms of DNA is that the cell has already completed meiosis. So, the correct option is B.

It is a complex molecule that contains all the information necessary to build and maintain an organism. It stands for Deoxyribonucleic acid. It is considered the genetic material in most organisms.

The skin cells in the G1 phase have an average of 12 picograms of DNA. As the amount of DNA in the G1 phase is 2C, hence 2C = 12 pg of DNA.

Now in the same organism, a cell from gonadal tissue is identified and that single cell contains 6 pg of DNA, which means, the amount of DNA is 6 pg that is C. Therefore, after the completion of meiosis, the cell contains half the amount of DNA as compared to the parent cell in G1.

So, Amount of DNA = C = 6 pg.

Therefore, the statement which is true about the single gonadal tissue cell with 6 picograms of DNA is that the cell has already completed meiosis.

The Himalayan region is home to the yak, a type of cattle. They have a reputation for having long, shaggy hair, which is used to create many different textiles, including wool. Yak wool is popular because it is soft, warm, and long-lasting and is frequently used to manufacture clothes and blankets.

Camels are widely known for their capacity to survive in difficult desert situations, and their wool is a valuable resource in many parts of the world. Clothing, rugs, and other textiles are frequently made from camel wool because it is cosy and soft.

Goats are another typical source of wool, especially in warmer locations where other types of wool are less common. Depending on the breed of goat and the quality of the wool, the term "mohair" or "cashmere" is frequently used to describe the wool from goats. Cashmere is appreciated for its warmth and luxurious feel, while mohair is renowned for its softness, sheen, and insulating qualities.

Despite the fact that there are numerous dog breeds with long, shaggy hair, none of them actually produce true wool. Dog hair is not often used to produce textiles since it is formed of a different kind of fibre than wool. Although some dog hair can be spun into yarn and used for crafts, it is not regarded as a true wool and is not widely utilised for the manufacturing of textiles.

Amino acids and Proteins

Explanation:

Plants as well as other living organisms require certain nutrients for their growth and development. One major inorganic nutrient that is needed by plants is NITROGEN, obtained in its compound form called nitrates. Nitrogen is necessary component for building amino acids and proteins in the cell because nitrogen is an integral element in the structure of AMINO ACIDS. Nitrogen makes up the amine functional group of amino acids (NH2).

Hence, If there were no nitrogen compounds in the soil, the most immediate effect on plants growing in that soil would be difficulty in synthesizing AMINO ACIDS and subsequently PROTEINS.

Surface ocean currents

Surface currents refer to movement of the top layer of ocean water. Surface water flows in to replace the sinking water, which in turn becomes cold and salty enough to sink.

examples of surface ocean currents are California Current (Cal) in the Pacific ocean basin and the Canary Current (Can) in the Atlantic ocean basin.

Deep ocean currents

Deep-water currents describe water movement patterns far below the ocean’s surface and the influence of the wind. When ocean water freezes, forming sea ice, salt is left behind causing surrounding seawater to become saltier and denser. Dense-cold-salty water sinks to the ocean bottom.
