Answers
Answer:
Atomic Models Of Elements: Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). ... Atoms are made up of protons and neutrons located within the nucleus, with electrons in orbitals surrounding the nucleus.
Lithium:Lithium is a chemical element with the symbol Li and atomic number 3. It is a soft, silvery-white alkali metal. Under standard conditions, it is the lightest metal and the lightest solid element. because it is present in trace amounts in virtually all rocks.
Florine:Fluorine is a chemical element with the symbol F and atomic number 9. It is the lightest halogen and exists at standard conditions as a highly toxic, pale yellow diatomic gas. As the most electronegative element, it is extremely reactive, as it reacts with all other elements, except for argon, neon, and helium.
Electron:Electron is a free and open-source software framework developed and maintained by GitHub. It allows for the development of desktop GUI applications using web technologies: it combines the Chromium rendering engine and the Node.js runtime.
Neutron:The neutron is a subatomic particle, symbol n or n⁰ , which has a neutral charge, and a mass slightly greater than that of a proton. Protons and neutrons constitute the nuclei of atoms.
Proton:A proton is a subatomic particle, symbol p or p⁺ , with a positive electric charge of +1e elementary charge and a mass slightly less than that of a neutron. Protons and neutrons, each with masses of approximately one atomic mass unit, are jointly referred to as "nucleons".

Answers
Answer:
B
Explanation:
An example of chemical digestion is the breakdown of nucleic acids, or nucleotides, which is in option e. Chemical digestion involves the breakdown of large, complex molecules into smaller ones, so here the correct option is option e.
Chemical digestion is a process that occurs in the digestive system, specifically in the stomach and small intestine, where complex macromolecules are broken down into smaller, simpler units through chemical reactions facilitated by digestive enzymes. Proteins are large macromolecules made up of chains of amino acids. Hence, here the correct option is option e.

which of these is an example of an abiotic factor
A:creosote plant
B:rocky desert soil
C:kangaroo rat
D:coyote
Answers
Answer:
[tex]\boxed {\boxed {\sf B. \ Rocky \ desert \ soil}}[/tex]
Explanation:
An abiotic factor is a part of an ecosytem, but it is not alive. Some examples include water, rocks, sunlight, and the atmosphere.
On the other hand, a biotic factor is a living part of an ecosystem. Some examples are animals, plants, and fungi.
Let's look at the answer choices.
A creosote plant (choice A) kangaroo rat (choice C) and coyote (choice D) are all living organisms. Therefore, they must be biotic factors.
However, rocky desert soil (choice B) is not living. It's a part of the ecosystem, but since it's not alive it must be abiotic.
Pyramids depicting the number of organisms or biomass may be inverted, upright, or even diamond-shaped.
Energy pyramids, however, are always upright. Why?
Answers
Answer:
The correct answer is - as energy lost at every trophic level.
Explanation:
In any ecological ecosystem the energy pyramids always upright unlike other pyramids such as biomass showing the number of organisms, that can be diamond shape, inverted or upright.
The main reason behind this is due to the fact that it is only a pyramid in the ecosystem that always unidirectional in the food chain which is always some energy lost with an increase in the trophic level in the food chain. This loss of energy always gets back to the atmosphere in each step of the food chain.
As the energy is lost at every trophic level, the energy pyramids are always upright. A further explanation is below.
In whatsoever biological environment, the energy pyramid always seems to be straight, unlike some of the other pyramidal, including such biomass, which might be diamond-shaped, overturned, as well as upstanding.Essentially the food chain is simply a pyramid, and there is always some power loss as that of the primary consumers throughout the chain increases.
Thus the response above is right.

Which is not a cost for organisms that sexually reproduce?
Answers
Answer:
Identical shape and structure.
Explanation:
Those organisms that reproduce sexually have high variations and differences between the parent and its offspring. They are not identical to each other because the offspring gains half characteristics from male parent and half from the female parent making it different from its parent. Identical feature is present in the organisms that reproduce through asexually means from only one parent so the identical shape and structure is not the cost of sexual reproduction.
Outline the effect of the following mutations:
TAG-> TAT
TAC-> TCC
Answers
Answer:
TAG-> TAT >> sense mutation
TAC-> TCC >> missense mutation
Explanation:
A sense mutation is a type of mutation that changes a stop codon into a sense codon, thus producing an elongated protein. The TAG codon (UAG in the RNA) is a stop codon, while TAT (UAU) encodes for tyrosine, thereby TAG-> TAT is a sense mutation. On the other hand, a missense mutation is a type of point mutation where a single nucleotide change generates a new codon which encodes a different amino acid. In this case, the TAC codon (UAC) encodes for tyrosine, while TCC (UCC) codon encodes for serine, and therefore TAC-> TCC is a missense mutation (Tyr to Ser mutation).

Because of reflection of light away from the marking
Explanation:
It is because the light from a vehicle falls on the road and its markings which then gets illuminated as light is reflected only in one direction.
But in case when the road is wet, light of vehicle reflects in different directions away from the markings on the road and hence they do not illuminate.
The reason why the given phenomenon about the effect of light and while driving is; Due to total internal reflection of light away from the marking.
What is reflection of light?Reflection of light is simply defined as the phenomenon where light is sent back after being incident on a surface.
Now, in this question, the light from a vehicle falls on the road and its markings and then gets illuminated as light is reflected only in one direction.
However, when the road is wet, the headlight of vehicles tend to reflect away from the markings on the road in different directions which make them not to illuminate.
Thus, we conclude that reason why the given phenomenon about the effect of light and water on driving is due to total internal reflection of light away from the marking.

Relate plant structure and function to the process of photosynthesis and respiration
Answers
Answer: Photosynthesis is a process through which green plants prepare their food by using carbon dioxide and water as reactants in the presence of sunlight energy. The food produced in the form of carbohydrate. Respiration is the process in which the biochemical oxidation of the food occurs.
Explanation:
The plant structures like leaves are specialized for performing the process of photosynthesis. These leaves have chlorophyll pigment which traps the light energy from sun which is required for splitting the molecules of water in the process of photosynthesis. Respiration occurs through stomata in leaves. But it also occurs in stems through lenticels and in specialized roots called pneumatophores via tiny pores.

13-22 Aquaculturists (people who farm marine resources, typically in semi-enclosed areas off the coast) have development methods of growing various invertebrates as food sources, such as clams, mussels, and oysters. Other widely consumed species, such as squid, have never been successfully grown in controlled marine environments, and so they remain wild caught. Why
Answers
Answer: There are several problems associated with handling of the squid.
Explanation:
Squid is a deep sea creature which becomes enormously big in size and difficult in handling in artificial water body or aquaculture.
It consumes and requires huge amount of food in the pre-larval stages typically phytoplankton and it becomes difficult to provide such food to them.
The maintenance of temperature, and salinity for the squid in aquaculture is difficult.
The sticky arms of the squid adhere to the surface of tub or human handler making it difficult to handle and can be poisonous to humans too.
