Answer:

eubacteria

Explanation:

I took the quiz :)

The organisms that belong to the Prokaryotic domain of life and it comes in three different shapes, such as cocci, rods, and spirals are known as Eubacteria.

What do you mean by the Prokaryotic domain?

The prokaryotic domain may be characterized as the kingdom of Prokaryotes is significantly made up of two domains namely, Archaea and Bacteria. These eubacteria are classified under the domain of bacteria which is represented by the relation based on the DNA experimental approach.

According to the context of this question, there are mainly three types of eubacteria commonly found. They are round (coccus), rod-like (bacillus), comma-shaped (vibrio), or spiral. All these types of different body plans, structures, and functions with respect to their morphology.

Therefore, eubacterium is a type of organism that belongs to the Prokaryotic domain of life and it comes in three different shapes, such as cocci, rod, and spiral.

What molecules are required for the Calvin cycle? (3 answers)

Answers

Answer:After the energy from the sun is converted and packaged into ATP and NADPH, the cell has the fuel needed to build food in the form of carbohydrate molecules. The carbohydrate molecules made will have a backbone of carbon atoms. Where does the carbon come from? The carbon atoms used to build carbohydrate molecules comes from carbon dioxide, the gas that animals exhale with each breath. The Calvin cycle is the term used for the reactions of photosynthesis that use the energy stored by the light-dependent reactions to form glucose and other carbohydrate molecules.

Explanation:The Interworkings of the Calvin Cycle

In plants, carbon dioxide (CO2) enters the chloroplast through the stomata and diffuses into the stroma of the chloroplast—the site of the Calvin cycle reactions where sugar is synthesized. The reactions are named after the scientist who discovered them, and reference the fact that the reactions function as a cycle. Others call it the Calvin-Benson cycle to include the name of another scientist involved in its discovery (Figure 5.14).

This illustration shows that ATP and NADPH produced in the light reactions are used in the Calvin cycle to make sugar.

Answer:

CO2, ATP, and NADPH

Some fossil snakes have remnants of hip bones and legs even though these animals had no legs. These remnant structures are best described as:

Answers

Some fossil snakes have remnants of hip bones and legs even though these animals had no legs. These remnant structures are best described as: vestigial structures.

Vestigial structures are organic structures that do not appear to fulfill any important biological function in the organism that possesses them.

These structures are preserved as an inheritance of the evolutionary process, because at some point in the history of evolution an ancestor of the current species had that structure.

These types of structures, which can be bones, organs, structures in the skin or any other part of the body, no longer offer any meaningful function for the body.

The presence of vestigial structures in animals is considered proof that evolution and natural selection exists.

Therefore, we can conclude that some fossil snakes have remnants of hip bones and legs even though these animals had no legs. These remnant structures are best described as vestigial structures.

Ciliated ependymal cells: A) help form the blood-brain barrier. B) circulate cerebrospinal fluid. C) form myelin in the brain and spinal cord. D) serve as wandering phagocytes during brain injury.

Answers

Ciliated ependymal cells: circulate cerebrospinal fluid.

Ependymal cells are a type of epithelial cell that is associated with the cavities of the body through which the cerebrospinal fluid circulates.

They are part of glial cells, which share space with neurons in the nervous system.

They create the membranes that keep cerebrospinal fluid circulating through the ependymal canal of the spinal cord and the cerebral ventricles.

For this, the ciliated structure that these cells present is essential for a correct movement of the cerebrospinal fluid, preventing it from spilling through other tissues and passing to areas of the body where it should not be.

The cilia move rhythmically creating tiny currents for fluid to flow through the central nervous system.

A small fraction of highly specialized and modified ependymal cells, called choroidal cells, are responsible for generating this essential fluid.

Therefore, we can conclude that ciliated ependymal cells circulate cerebrospinal fluid.

What is Plant cell?

Plant cells are defined as eukaryotic cells that contain a true nucleus as well as specialized structures known as organelles that perform certain specialized functions. Plant and animal cells both contain a nucleus with similar organelles but plant cells differ due to the presence of a cell wall outside the cell membrane.

In the given figure, labelled organelles function are as follows:

Vacuole stores food, extra water, and waste while cell membrane permits selective passage of things into and out of the cell. The cell's nucleus serves as the activity's control centre, while the cytoplasm is the fluid that gives the cell its jelly-like consistency. Chloroplasts contain a substance called chlorophyll that is a green pigment that aids in photosynthesis. The cell wall of a plant gives it form, stiffness, strength, and protection.

What are Neurotransmitters?

Neurotransmitters may be defined as the type of chemical substances that are correspondingly liberated at the end of a nerve fiber by the arrival of a nerve impulse and, by diffusing across the synapse or junction. They are released in the location known as the synaptic cleft.

The receptors of these neurotransmitters are present in the plasma membrane of postsynaptic cells which selectively bind the transmitter. They are integral membrane glycoproteins with multiple transmembrane segments.

Answers

Answer:

Explanation:

The one valence electron from sodium would be transferred to the bromine atom so they can both have an octet.

Which two atoms form an ionic bond?

Answer : A

Explanation : Ionic bond is a type of chemical bond and binds the chemical molecules together. Ionic bond is formed by the transfer of electrons from an electropositive element ( metal) to the electronegative element (non metal).

Sodium is an electropositive element and contains one positive charge. Bromine is an electronegative element with a single negative charge over it. Sodium gives the electron to bromine and results in the formation of ionic bond.

Thus, the correct answer is option (C).

Explanation:

Which of the following sentences state a significant conclusion that Gregor Mendel drew from his experiments with pea plants? Traits are inherited in discrete units and are not the result of "blending." Genes are composed of DNA. Recessive genes occur more frequently in the F1 generation than do dominant ones. There is considerable genetic variation in garden peas.

Answers

Mendel concluded that the alternative forms of each trait are coded by discrete factors, which were called alleles that combine in pairs to express the trait. Traits are inherited in discrete units and are not the result of "blending."

------------------------

After making many crosses that involved different traits -such as plant height, or flower colors-, Mendel observed that, per trait, the F1 only expressed one of the alternative forms, while de other one disappeared.

Mendel named dominant the expressed variant.

Mendel then let these new plants auto pollinate and observed the results in the second generation, F2.

He saw that the variants that had previously disappeared among the F1, reappeared again. Both alternatives for each trait were present in the F2.

Mendel named recessive the second alternative variant.

Mendel explained his results by arguing that discrete factors were responsible for these phenotypes.

These factors should have been present in the F1 in pairs.

One of them came from one parental plant, and the other factor came from the other plant.

These factors separated again during sex cells formation, producing two types of gametes, each with only one factor.

Mendel conclusion about his experiments was that per trait -flower color of plant length-, each plant had a pair of factors -which he named alleles-, and that each factor coded for one of the alternative forms of the traits -white or purple, tall or short-.

He thought that alleles separate -segregate- during the process of gamete formation.

The First Mendel's Law is the first conclusion he took about his experiments and is known as the segregation principle.
