Two principal types of connective tissue in a muscle are

Connective tissue that are found in muscle are of 3 types-Endomysium,Perimysium and epimysium.

Explanation:

Endomysium is called as areolar connective tissue that have nerve and capillaries.

It attaches  with epimysium and perimysium and form collagen fibers of tendons.

Perimysium is  a sheath of connective tissue that transmit lateral contractile movement.

Epimysium is the layer that is formed by  irregular connective tissue .

This layer covers the muscle and provide  protection from friction against muscle and bone.

This layer contain fascia and other connective tissue.

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.

if you add everything up correctly you should get 69 i got this because 50 plus 19 is it
