11. Match the term with the definition regarding the anatomical position1. Arms A Erect 2. Eyes B. At the sides 3. Head c. Flat on the floor 4. Feet D. Level 5. Body E. Facing forward
The standard anatomical position refers tothe points of reference to compare and describe parts of the body. 1.B) Arms at the sides/2.E) Eyes Facing forward/3.A) Erect head/4.C)Feet Flat on the floor/5. D) Body Level
There is a standard anatomical position to describe an individual's body and general anatomy.
The individual's position must be standard to allow comparisons with minimal variation while comparing or describing the anatomy and the position of different structures.
The standard anatomical position has different reference points, such as a straight head or the palms of the hands facing forward.

In humans, one function of the skin is to prevent water loss. Skin releases water or holds in water when necessary.Which two structures in plants have a similar function to skin?
> roots and chloroplasts
> phloem and roots
> cuticle and stomata
> stomata and phloem
Cuticle and stomata in plants have a similar function to skin.
What are the functions of cuticles?
The cuticle is well known for its functions as a diffusion barrier limiting water and solute transport across the apoplast and for its protection of the plant against chemical and mechanical damage, as well as pest and pathogen attack.
In some higher plants, the cuticle is a water-impervious protective layer covering the epidermal cells of leaves and other parts and limiting water loss. It consists of cutin, a waxy, water-repellent substance allied to suberin, which is found in the cell walls of corky tissue.
The cuticle itself comprises three layers: the cuticular layer; cuticle proper; and epicuticular waxes. The cuticular layer is the innermost layer, which overlays the primary wall and consists of cellulose and other polysaccharides along with cutin and wax.
Can organisms plan and willingly change theirmutations in their genes? Why or why not. simple answer 1 sentence please
Organisms cannot willingly change their mutations as these things occur by chance and within the genetic code which the organisms have no direct power over.
How do plant cells that do not have chlorophyll get food?
All plants cells have chlorophyll so there is no problem
Why is a cap added to mRNA, but not to tRNA or rRNA?A-Transfer RNA and rRNA exhibit complex structures with double stranded regions. The three-dimensional shapes of these molecules keep the 5\' end of the RNA away from the enzymes that process the cap.B-Transcription and processing of mRNA occur in the nucleus, where cap binding proteins are found. These proteins, which add and modify the cap, are not found in the cytoplasm, where tRNA and rRNA are transcribed and processed.C-Each of the three types of RNA are transcribed by different RNA polymerases. Only RNA polymerase II, involved in mRNA synthesis, contains a domain capable of interacting with enzymes that form the cap.D-Only mRNA contains introns. Capping occurs simultaneously with intron removal because the same enzymes and proteins involved in both of these processes must bind to RNA at the same time.
The correct option is C ' Each of the three types of RNA are transcribed by different RNA polymerases. Only RNA polymerase II, involved in mRNA synthesis, contains a domain capable of interacting with enzymes that form the cap.'
All the different type of RNA's undergo the process of transcription. However, their transcription is carried on by different types of RNA polymerases.
The transcription of the mRNA is carried by RNA polymerase II. The process of capping is essential so that the mRNA is stopped from degradation.
The rRNA is transcribed by RNA polymerase I which cannot add a cap tothe RNA.
The tRNA is transcribed by the RNA polymerase II, but the domain is different which cannot undergo the process of capping.
Which of the following types of cells can directly kill cells and secretes a chemical known as perforin which accomplishes the killing by producing pore-like openings in the membranes of cells?a. Cytotoxic T cells b. Helper T cells c. Antibodies d. Natural killer cells
Cytotoxic T cells
Perforin is the cytosolic protein and upon degranulation forms pores in the target cell. Perforin protein helps in the transport of water and ions.
Perforin is present in the granules of cytotoxic T cells. These cells have the ability to kill virus infected cells and cancer cells. Cytotoxic T cells bind with the class 1 MHC molecules. These cells are also known as CD8+ T cells.
