6 0

Answer:

Clonal selection can be defined as methods or processes that shows(describes) tthe way  lymphocytes  do react or  respond to the various different types of antigens present in a particular body. Clonal selection is of the notion that  lymphocytes are taken during antigen presentation .

Explanation:

Clonal selection is important as it is  sometimes used during negative selection during T cell maturation. it is believe to be a major cause mutations of antigen-binding affinity in memory cells during clonal expansion .

Solar, wind, and hydroelectric energy<br> are examples of<br> resources.
strojnjashka [21]

Answer:

Renewable Energy Resources.

Explanation:

Unlike fossil fuels which cannot be recovered when destroyed, these sources of energy can be recovered by a means of recycling . Recycling here reduces solid wastes which is one of the causes of land pollution.

Hydroelectric schemes can only be built in mountain regions where rainfall and rivers are plentiful which involves upset of aquatic ecosystem. This poses a dangerous pollution problem though.

Wind generators and solar panels are not very efficient energy producers. However, future schemes for producing solar energy via solar satellites are promising.

huntington disease is a dominant disease caused by expansion of the trinucleotide repeat region of the htt gene that results in
Travka [436]

By haphazardly introducing a transgene harboring a disease-causing mutant variant of the HTT gene into the genome of a mouse or primate, it is possible to produce an animal model with the majority of the symptoms of this condition. Here option B is the correct answer.

Huntington's disease is an uncommon, genetic condition that results in the gradual degeneration of brain nerve cells. Huntington's illness, which frequently results in mobility, cognitive, and psychological problems, has a substantial impact on a person's functional capacities.

A DNA region known as a CAG trinucleotide repeat is involved in the HTT mutation that causes Huntington's disease. Three DNA-building building pieces that are repeated several times in a row make up this region.

Complete question:

Huntington's disease is a dominant disease caused by the expansion of the trinucleotide repeat region of the Htt gene that results in the production of a Huntingtin protein with an expanded number of glutamines. An animal model with most features of this syndrome could be created by

A - knocking in a wild-type copy of the Htt gene to a mouse or primate genome.

B - randomly inserting a transgene containing a wild-type allele of the Htt gene to a mouse or primate genome.

C - randomly inserting a transgene containing a disease-causing mutant allele of the Htt gene into a mouse or primate genome

D - knocking out one copy of the wild-type Htt gene from a mouse or primate genome.

E - knocking out both copies of the wild-type Htt gene from a mouse or primate genome.

olasank [31]

Answer:

Plant is a common example of a Producer.

Producers are also known as autotrophs.They are organisms which make their own food. They do so by getting energy from chemicals or the sun and with the help of water convert the energy into useable forms such as sugar.

The order of Producers that colonize the land After Lichens include

Annual herbaceous plants

Perennial herbaceous plants and grasses

HELP PLEASE!<br> Explain the Linnaean system of classifying organisms.
Nady [450]

Answer:

The Linnaean system is based on similarities in obvious physical traits. It consists of a hierarchy of taxa, from the kingdom to the species. Each species is given a unique two-word Latin name. The recently added domain is a larger and more inclusive taxon than the kingdom.
