a structure that is composed of at least two different tissue types and has discrete boundaries is called a(n)

Answers

Answer 1

An organ is defined as any anatomical structure with discernible structural boundaries, at least two distinct tissue types, and a distinct function distinct from the structures around it.

What do we mean by tissue?

Simply put, tissues are groups of cells that have a similar shape and function. They form a cellular organisational level between cells and organ systems.

The four basic types of tissue are connective tissue, epithelial tissue, muscle tissue, and nervous tissue. Connective tissue holds other tissues together and supports them (bone, blood, and lymph tissues). Epithelial tissue serves as a covering (skin, the linings of the various passages inside the body). The Old French word tissu, which means "a ribbon, belt, or piece of woven material," is where the noun tissue originates. As a verb, "weave fabric strands" is what tissue means. Tissues are now thought of as disposable paper used for wrapping gifts or blowing our noses.

most rna molecules have three phosphate groups at the 5 end, but dna molecules never do. explain this difference.

Answers

RNA is composed of two strands of nucleotides joined together in a double helix, while DNA is composed of a single strand.

What is the difference between RNA and DNA?

DNA is a double-stranded molecule shaped like a double helix that stores genetic information. RNA is a single-stranded molecule that converts the genetic information encoded in DNA into proteins.

The structural variations between DNA and RNA are to blame for this. DNA is made up of two strands of nucleotides linked together in a double helix, whereas RNA is made up of a single strand. Phosphate groups in DNA are connected to the sidewalls of base pairs, whereas phosphate groups in RNA are associated to the 5' end of the molecule. This enables the RNA molecule to connect with other molecules in the cell more easily and engage in a range of biological functions.

the endergonic conversion of adp to atp requires more than 30 kj/mol. the hydrolysis of phosphoenolpyruvate to pyruvate drives the conversion of adp to atp. what must be true about this hydrolysis?

Answers

The hydrolysis reaction is more exergonic than the endergonic conversion of ADP (the endergonic conversion of adp to atp requires more than 30 kj/mol) which is the truth about how phosphoenolpyruvate is converted to pyruvate to promote the conversion of adp to atp.

An ATP molecule becomes an ADP when the tail of the molecule's phosphate group is severed (via hydrolysis) (adenosine diphosphate). That hydrolysis produces energy and is an exergonic reaction. The phosphate is attached to ATP by weak bonds. Although they are not strong (if they were strong, it would take a lot of energy to break them), they are known as high energy bonds. Consider ATP as a spring-loaded molecule with the last phosphate simply tacked on.

Since I could not find the data groups, I will explain what the mean is and how to get it, and then I will provide an example for you to understand and use as a guide.

What is the mean?

The Mean, together with media and mode, is a central tendency measure. It is used in statistical analysis to identify the tendency of a data set concerning information inclination.

This measure is used to expose the result of a research in a resumed way to avoid providing extensive information.

The Mean is the average value of a data set.

To calculate the mean you just have to add all the data and divide it by the amount of data you have.

Which complex in the electron transport chain does not contribute to the proton gradient across the mitochondrial membrane?

Answers

The complex in the electron transport chain does not contribute to the proton gradient across the mitochondrial membrane is complex II

Electron transport is the final part of aerobic respiration which occurs in mitochondria to produce ATP. At this stage the NADH and FADH2 produced from previous processes such as glycolysis and the Kerb cycle are transferred to the inner mitochondrial membrane to be converted into ATP in the electron transport chain.

The electron transport chain involves three enzyme complexes embedded in the mitochondrial inner membrane that can transport enzymes and pump protons. Complex II is a component of electron transport that only accepts electrons from FADH2 and does not pump protons across the mitochondrial membrane. Therefore, this process produces a small amount of ATP.

Answers

Hibernation and camouflage are not directly related to precipitation levels, as hibernation is a type of sleep that occurs during the winter months and camouflage is a method of concealment used by animals. However, the amount of precipitation in an area is largely determined by its climate.

What is hibernation?

Hibernation is a condition of hibernation that certain animals adopt during the winter or cold weather to save energy. Hibernation causes an animal's heart rate, breathing rate, and body temperature to drop dramatically, allowing it to subsist on stored energy until conditions improve.

In general, hibernation and camouflage have no direct association with precipitation amounts. Hibernation is a sort of slumber that certain animals experience throughout the winter, while camouflage is a way of hiding employed by animals to fit in with their surroundings.

what types of mutant commonly result from regulatory mutations that increase the rate of transcription of a gene? see section 4.1 (page 107

Answers

The types of mutant commonly result from regulatory mutations that increase the rate of transcription of a gene is hypermorphic.

Generally speaking, increasing the rate of transcription causes the generation of extra gene product, which causes extra gene activity.

A mutant could produce an active product with a new and different function or more of the active product (hypermorph) if it has a gain-of-function allele (neo morphs). Last but not least, antimorph alleles, sometimes referred to as dominant negative mutations, have an activity that is dominant and opposing to that of the wild-type product.

As a result, mutant alleles can arise from mutations (changes in a gene's sequence) that do not produce the same quantity or kind of active product as the wild-type allele. One of five categories—amorph, hypomorphic, hypermorph, neomorph, and antimorph—can be applied to any mutant allele.
