VARVARA [1.3K]

Answer: conditioned

Bobby touches his newborn brother's palm, and his little brother takes hold of Bobby's finger and will not let go. This is known as the conditioned reflex.

Explanation:

A conditioned reflex is a response or behaviour learned after birth. So, once the newborn acquires this learned response, they can perform them even without thinking about it.

Thus, Bobby's brother (the newborn) holding on to his finger and not letting go shows that it is a conditioned reflex

Approximately 90% of human cancer cells exhibit significant levels of telomerase. Does this mean that telomerase is an oncogene?
alukav5142 [94]

Answer:

No, telomerase is not an oncogene. It prevents the senescence that would occur due to shortened telomeres, but the cell proliferation might still be mitogen-dependent.

Explanation

telomerase is not responsible for causing  deregulation while oncogenes cause deregulation .

Telomeres length shorten after the cell division which stops them to divide again and cell die.

Telomerase prevents this decline in some kinds of cells, including stem cells, by lengthening telomeres, and the hope was that activating the enzyme could  prevent senescence.

Bond [772]

When we compare male and female, the prevalence of osteoporosis and the rate of fractures are much higher in postmenopausal women than in men of the same age.  Because of that, this condition is often called “woman’s disease”. One of the explications is that women have smaller and thinner bones than men. Also, estrogen decreases when women reach menopause, which can cause bone loss.</span>
