<span>The blood pressure measured in the calf is lower than it is in the arm. Blood pressure in the body is highest right at the ascending arch of the aorta. From that point, the pressure decreases as blood moves "distally" from the heart. Purely mechanically, legs are farther away from the heart than are the arms, thus pressure is less.</span>
Eukaryotes are organisms whose cells have a nucleus enclosed within a nuclear envelope.
Answer:
The organism belongs to the Protista kingdom as it is unicellular, has cell walls, and has the ability to produce spores.
The genetic characteristic of two different organisms are induced into a new host organism for the purpose of producing new genes.
<u>Explanation:</u>
In the field of bio technology, Recombinant DNA technology plays a very important role. This helps in the production of genes. The first thing insulin of human was produced with this technology. In this technology, the gene that is to be produced is cut and it is placed inside a host organism where it gets multiplied.
This technology uses five steps in gene production. Firstly, the DNA that is essential will be cut. this is done by restriction site. PCR is used secondly in order to amplify the copies of the genes. Then these are induced into Vectors after which they will again be introduced into a host organism. Then finally the results will be the genes of the desired characteristics.
The arrangement of homeotic genes along chromosomes of vertebrate and invertebrate animals corresponds to the expression pattern of the genes along the anterior-posterior axis of the developing embryo.
<h3>What are homeotic genes?</h3>
- Homeotic genes are a group of body pattern forming genes which control the development along the anterior- posterior axis of the developing embryo.
- These encode transcription factors which control and specify the genes involved in body patterning. These provide identity to the segments during embryo formation.
- Genes located in the 5’ end act on posterior side whereas the genes on 3’ end act on anterior region.
- Homeotic genes are evolutionary conserved and control body specification, patterning and differentiation.
- The loss of function of any of the gene changes the body pattern and affects the development.
