This bacterial overgrowth can happen either when bacteria from one part of the digestive tract travel to the small intestine or when naturally occurring bacteria in the small intestine multiply too much.

Does your child seem much shorter - or much taller - than other kids his or her age? It could be normal. Some children may be small for their age but still be developing normally. Some children are short or tall because their parents are.

But some children have growth disorders. Growth disorders are problems that prevent children from developing normal height, weight, sexual maturity or other features.

Very slow or very fast growth can sometimes signal a gland problem or disease.

The pituitary gland makes growth hormone, which stimulates the growth of bone and other tissues. Children who have too little of it may be very short. Treatment with growth hormone can stimulate growth.

People can also have too much growth hormone. Usually the cause is a pituitary gland tumor, which is not cancer. Too much growth hormone can cause gigantism in children, where their bones and their body grow too much. In adults, it can cause acromegaly, which makes the hands, feet and face larger than normal. Possible treatments include surgery to remove the tumor, medicines, and radiation therapy.

Which statements are true for dna and rna? check all that apply?

LekaFEV [45]

Since there are no given choices, I would just compare and contrast DNA and RNA. These are the two types of nucleic acids in the human body. The structural unit of nucleic acids are composed of repeating units of monomers called nucleotides. Nucelotides are composed of three functional groups: sugars which are specifically pentoses (5-Carbon sugars), phosphate group and nitrogenous base.

Now, the RNA and DNA differ in the composition of these sugars and the bases. Based on the nitrogenous bases and sugar, the DNA has a deoxyribose as the sugar and its 4 bases are adenine, guanine, cytosine and thymine. For RNA, the sugar is ribose while its 4 bases are adenine, guanine, cytosine, and uracil.

They also differ in their structure. DNA is a double stranded β-helix with a long chain of nucleotides. RNA is composed of a shorter chain with a single strand α-helix structure.

Lastly, they differ in their functions. The DNA is responsible for storing the genetic information while the RNA is responsible for transporting the genetic information to the ribosomes which synthesize proteins.

The functions of lipids include storing energy, signaling, and acting as structural components of cell membranes.

Example : Fats

functions of carbohydrates in the body are to provide energy, store energy, build macromolecules, and spare protein and fat for other uses.

Example : Glucose

Nucleic acids function to create, encode, and store biological information in cells, and serve to transmit and express that information inside and outside the nucleus.

Example: DNA

.Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells and organisms, and transporting molecules from one location to another.

Example: Keratin

Proteins produced by the immune system to destroy substances containing antigens are called

Tomtit [17]

Antibodies, also called immunoglobulins, are proteins manufactured by the body that help fight against foreign substances called antigens. When an antigen enters the body, it stimulates the immune system to produce antibodies. (The immune system is the body's natural defense system.) The antibodies attach, or bind, themselves to the antigen and inactivate it.

Part A - Modification of chromatin structure Which statements about the modification of chromatin structure in eukaryotes are tr

Salsk061 [2.6K]

Answer:

Some forms of chromatin modification can be passed on to future generation of cells

Acetylation of histone tails in chromatin allows access to DNA for transcription

DNA is not transcribed when packaged tightly in a condensed form

methylation of histone tails can promote condensation of the chromatin

Explanation:

chromatin modifications that can be passed on includes epigenetic modifications that are heritable changes made to the chromatin structure that does not involve the DNA sequences. Some epigenetic modifications include DNA methylation and Histone modifications. examples of histone modification include acetylation, methylation, phosphorylation, ubiquintylation etc. All these function either in allowing the DNA become more accessible to transcritional factors or vice versa. for exmple, histone tail acetylation encourages unwounding of nucleosomes allowing transcriptional factors to have access to the DNa while histone tails methylation further tightens the nucleosomes promoting condensation of the chromatin.
