Based on the picture, which statement about plants and earthworms in this garden is true? A. Earthworms are harmful to the roots of plants because they remove nutrients and water from the soil, which plants need to produce food. B. The plants use oxygen from the soil to produce food, and the earthworms use carbon dioxide released by the plants to produce energy C. Earthworms loosen and fertilize the soil near the roots, which helps the roots of the plants get nutrients and water from the soil. D. The plants serve as food for the earthworms for energy, and the earthworms then give this energy to the plants in the garden.​

explanation:

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.

the level of progesterone is low at the pre-ovulatory phase of the cycle but it gradually increases and the levels are high at the luteal phase. if pregnancy occurs, the level of progesterone will be high throughout the pregnancy.

if egg is fertilized and the mother gets pregnant, progesterone starts preparing the uterus for the implantation. it starts building up the lining of uterus and make it hostile of the period of pregnancy.
