Answer:
The correct answer is ''All of the choices are correct.''
Explanation:
Pregnant women are a risk group for listeriosis, the disease caused by the Listeria monocytogenes bacteria found in contaminated food. This organism can cross the placenta and affect the fetus. Due to the decrease in cellular immunity, pregnant women are part of the population at risk and are 17-20 times more likely to develop listeriosis after the consumption of contaminated food and it usually occurs from the third trimester and appears as a disease mild with not very high fever, joint and muscle pain. Listeriosis can cause miscarriages during the first three months of pregnancy. As the third trimester is reached, the mother is at greater risk. It presents a 40-50% fetal or neonatal mortality. In the first or second trimester it produces septic abortions and intrauterine fetal death, in the third trimester she produces chorioamnionitis and premature labor. In 1/3 cases it can occur asymptomatically in the fetus / neonate. In newborns, listeriosis can cause blood infections and meningitis.
All of the answers would be correct,

Ans.
Testes and ovaries are male and female reproductive organs, respectively. These organs are similiar as testes produce male gametes or sperms by the process of spermatogenesis and ovaries produce female gametes or ova by the process of oogenesis.
These gametes fuse together to form zygote that develops into a multicellular organism. Thus, the correct answer is 'option A). both produce sex cells.'
Price of photosynthesis will increase as the quantity of collisions between enzymes and substrate will increase. this is the top-quality temperature. The enzymes begin to denature, so the fee of photosynthesis decreases.
Increase in enzyme attention will growth the charge of photosynthetic and respiratory reactions, furnished that there are substrates available to bind to. once all substrate is bound by enzymes, the reactions, the response will no longer increase, since there may be not anything for extra enzymes to bind to.
Enzymes are proteins that catalyze, or affect the fee, of chemical reactions without themselves being altered inside the process. precise enzymes catalyze every mobile reaction. the main position of enzymes at some point of the respiratory reaction is to help in transferring electrons from one molecule to some other.

An egg is the organic vessel containing the zygote in which an animal embryo develops until it can survive on its own, at which point the animal hatches. An egg results from fertilization of an ovum. Most arthropods, vertebrates, and mollusks lay eggs, although some do not, such as scorpions and most mammals.
Reptile eggs, bird eggs, and monotreme eggs are laid out of water, and are surrounded by a protective shell, either flexible or inflexible. Eggs laid on land or in nests are usually kept within a favorable temperature range (warm) while the embryo grows. When the embryo is adequately developed it hatches, i.e. breaks out of the egg's shell. Some embryos have a temporary egg tooth with which to crack, pip, or break the eggshell or covering.
