An organism that is eukaryotic, multicellular, and lacks a cell wall would be classified in which kingdom : (Choose all the apply)
A- Protista
B- Fungi
C- Animalia
D- Archaebacteria
E- Eubacteria
The correct answer to the given question of organism and it's kingdom is option C. Animalia.
Kingdom Animalia is characterized by heterotrophic, eukaryotic organisms that are multicellular and whose cells lack cell walls.
Kingdom citizens Despite the fact that they are unable to produce their own sustenance, which is one of the most distinctive characteristics of plants, Animalia lack a cell wall, which is present in plant cells. With the exception of a few, the majority of animals are mobile, which helps them, among other things, to successfully respond to stimuli and seek food. Additionally, one can go deeper into the structure, sexuality, and growth traits of animals.
The classification diagram for the animal kingdom makes it easier to understand the various groups that animals fall under. The group's knowledge of many animal kingdom facts is also aided by the kingdom chart.

8. Why did the warning label on the bag say "not for direct infusion?" What does that mean?
Answer:
The treatment of severe hypernatremia can be challenging, especially in patients with preexisting conditions that may seem to limit therapeutic options. Such a situation recently resulted in an ill-conceived decision to give sterile water for injection IV to an elderly patient who had been admitted to an ICU with pneumonia, CHF, respiratory failure, and severe hypernatremia. The physician did not want the patient to receive any further infusions containing sodium. But the patient also was severely hyperglycemic. The physician's concern with giving sodium or dextrose to a patient with CHF and a high blood sugar led to an order to change the patient's peripheral IV to "free water" at 100 mL/hr.

The tree tells us that modern humans and Neanderthals are more closely related than either is to the fossils from the Denisova Cave.
What are Fossils?
Fossils are the remains of ancient plants and animals that have been preserved in rock, often over millions of years. Fossils may include bones, shells, impressions, or traces of organisms that are embedded in sedimentary rock. They provide evidence of the history of life on Earth and offer clues to the past environment.

calculate the total number of oxygen, nadph, and atp molecules that are produced when 12 water molecules complete the light-dependent reactions
6 O2 molecules, 12 NADPH molecules, and 18 ATP molecules are produced when 12 water molecules complete the light-dependent reactions.
What are light-dependent reactions?
In the presence of sunshine, light-dependent processes take place in the thylakoid membrane of the chloroplasts. These processes transform the solar energy into chemical energy. The photosynthesis process is carried out by the photosystem, which receives energy from the sun through the chlorophyll in plants.
They need light to function, and their overall conversion of water molecules to oxygen produces ATP molecules from ADP and Pi and NADPH molecules from the reduction of NADP+. The Calvin cycle can employ the ATP and NADPH that are created on the stroma side of the thylakoid membrane.
The "normal" form of the light-dependent processes, known as non-cyclic photophosphorylation, involves the removal of electrons from water and their passage via PSII and PSI before arriving at NADPH. Light must be absorbed twice throughout this process, once in each photosystem, in order to produce ATP. In fact, it uses light energy (photo) to create ATP from ADP, hence the name "photophosphorylation" (phosphorylation).

drag the correct labels onto the nucleotides in the rna transcript. not all labels will be used.
The information contained in the DNA sequence of one or more genes is converted during transcription into a strand of RNA, also known as an RNA transcript. As a mobile molecular copy of the original DNA sequence, the resulting single-stranded RNA molecule functions as ribonucleotides with the bases adenine (A), cytosine (C), guanine (G), and uracil (U).
What is RNA?
All living cells contain ribonucleic acid, also known as RNA, a nucleic acid that resembles DNA in structure. But unlike DNA, RNA is typically single-stranded. As opposed to DNA's deoxyribose backbone, an RNA molecule's backbone is built up of alternating phosphate groups and the sugar ribose. Adenine (A), uracil (U), cytosine (C), or guanine are the four bases that are joined to each sugar (G). Cells contain a variety of RNA forms, including messenger RNA (mRNA), ribosomal RNA (rRNA), and transfer RNA (tRNA). Some RNAs also have a role in controlling how genes are expressed. RNA serves as certain viruses' genomic material.
The RNA product is nearly identical to the non-template DNA strand, also known as the sense strand, and complementary to the DNA template strand.
The main distinction is that all of the T nucleotides in RNA are changed to U nucleotides, which are integrated during RNA synthesis whenever an A is present in the adjacent antisense strand. RNA polymerases are enzymes that carry out transcription by joining nucleotides to create an RNA strand (using a DNA strand as a template).

Explain thoroughly salinity, density, oceanic currents, and temperature as it relates to density. Oregon’s Rain shadow effect.
Salinity (from Latin: salinitas) is a measure of the amount of salts existing in natural bodies of water. The density of a body is defined as the quotient between the mass and volume of that body. Ocean current or marine current is a continuous and directed flow of water within the ocean, being generated by forcings such as wind and Coriolis effect. Rain shadow, also known as Chinook or Föhn effect, consists of an area usually surrounded by mountains that has much lower precipitation rates than the surrounding area.
What is Rain shadow effect?Mountains and other topographic features can have a tremendous influence on precipitation. Rain shadows can be some of the driest places on Earth; The Atacama Desert, in the shadow of the Andes Mountains, can go decades without receiving any rain. Several factors, including prevailing winds, topographic features, and local weather patterns contribute to the formation of rain shadows or dry regions on the sheltered side of some mountain ranges.
Prevailing winds are predictable winds that occur frequently in specific locations. When a mountain range runs perpendicular to the prevailing winds, the winds carry moisture towards those mountains on the downwind side. If the winds have an extensive search - the distance the wind is able to travel over open water - the air will accumulate considerable moisture. When prevailing winds push this moisture-laden air against topographic features like mountains, forcing it upward, rain results.

True. The oxygen atoms in water molecules are the source of the oxygen gas generated during photosynthesis. The plant's stomata are the entry point for the carbon dioxide required for photosynthesis.
The process of photosynthesis is where plants and certain bacteria produce oxygen. Oxygen is both consumed and produced by plants during respiration (via photosynthesis). Ozone (O3), a molecule made up of three oxygen atoms, is another product of aerobic respiration, as is carbon dioxide (CO2). When an organic molecule is oxidized, CO2 is frequently the end result. For example, photosynthesis requires six molecules of CO2 to make one molecule of glucose, and as a byproduct, six molecules of oxygen are also released.In the presence of sunshine, photosynthesis is the process through which plants absorb carbon dioxide and water.

Negative Feedback Mechanism
