The deficiency of growth hormone during bone formation would cause a decreased proliferation of the epiphyseal plate cartilage. Growth hormone is a peptide hormone secreted by the pituitary gland under the control of the hypothalamus. It directly through IGF-I stimulates osteoblasts proliferation and activity, promoting bone formation. In addition it also stimulates osteoclast differentiation and activity, promoting bone resorption. Therefore, growth hormone is an important hormone in bone formation.

O QUE É UM CLONE? EXPLIQUE COMO OCORRE A CLONAGEM EM MAMÍFEROS.
Pavlova-9 [17]

Answer:

A clonagem é a obtenção de duas células idênticas com o mesmo código genético que o produto da reprodução assexuada.

Nos mamíferos, a clonagem ocorre através de células somáticas, onde há um núcleo doador e um oócito que se unem por meio de um choque elétrico, formando o embrião que resultará em um ser vivo clonado, um exemplo de essa era Dolly, a ovelha.

Explanation:

Na clonagem de mamíferos, o embrião é responsável por ter caracteres da ovelha doadora, ou seja, será a imitação do código genético desse animal que empresta a célula doadora ao úbere.

If a biologist wanted to analyze the evolutionary relationship in a gene that is found in both eukaryotes and bacteria, which of
riadik2000 [5.3K]

Answer:

A) histone coding genes

Explanation:

Histones are the proteins involved in the packing of DNA in eukaryotes. They are positively charged proteins and are not found in bacteria. To analyze the evolutionary relationship in a gene between eukaryotes and bacteria, one must choose the gene present in both of them. The tRNA, rRNA and hexokinase encoding genes are common to both bacteria and eukaryotes. Therefore, one of these genes may be chosen for the study. However, histone encoding genes are not present in the genomes of bacteria. Therefore, the study of the histone encoding gene would not be useful for the mentioned purpose.

Some people worry that the increasing number of cell phones will cause cancer because of the energy of the radio waves they emit
-BARSIC- [3]

Answer:

No.

Explanation:

There is no clear evidence which indicates that cell phones will cause cancer because they emit very low intensity of radio waves but it can cause other diseases. Diseases such as brain tumor, male infertility and ear hearing function can be adversely affected by using cell phones due to the radio wave they emit. So we can say that cell phones will not the cause of cancer disease.
