The second law of thermodynamics is a statement of the law of conservation of energy say that heat cannot be completely converted into mechanical energy
Answer:
olfactory lobes
Explanation:
The correct answer would be olfactory lobes.
Murky waters are generally dark, and contains very little (low) light. Fishes that live in murky water need to be specially adapted in order to be able to live in such environment. These adaptations could be in terms of:
- A well developed lucidum tapetum, a layer of protein crystals known as guanine which enables them to see through low light and act as a kind of 'night vision'.
- A well developed olfactory lobe which receives and process information from the olfactory nerve with high efficiency and generally serves to improve the sense of smell.
Answer:Some toxic chemicals can make the body shut down and not function properly.
Explanation: Some gasses alter your cellular membrane like carbon monoxide or cyanide which affects your brain functions
Answer:
The results of the heat wave are the rising of sea levels, the oceans became more acidic, and species disappeared
Explanation:
About 56 million years ago, heat wave occurs due to the increase in the concentration of greenhouse gases which are present in the atmosphere. We know that greenhouse gases such as carbon-dioxide etc were the main cause of global warming. Due to this warming, many temperature sensitive species die, melting of ice occurs which increases the sea level and carbon-dioxide deposition occurs in the ocean water which make the water more acidic and the life of marine animals will be adversely affected.
Answer:
The mitochondria and Golgi apparatus are packaged into the head of the sperm.
Explanation:
Spermatogenesis is the production of male germ cells. Sufficient stimulation with sex hormones, especially testosterone, and a lower temperature, which is achieved by placing the testicles in the scrotum, are required for the correct course of spermatogenesis. Sperm production has three phases: reproductive, growth and maturation. At the beginning of sperm development are spermatogonia, which are male primordial cells. They have a spherical shape and are located at the edges of the seminal canals. Spermatogonia is mitotically divided. On the one hand, in order to preserve their numbers, and on the other hand, their division produces primary spermatocytes, which lie above the layer of spermatogonia. Primary spermatocytes are diploid, but after the first meiotic division, haploid secondary spermatocytes are formed from them. They still have double chromatids, so a second meiotic division soon occurs, the product of which is spermatids. Spermatids are already fully haploid and do not divide further. Spermatids then undergo a process of spermiogenesis, in which the nucleus condenses, forming a flagellum and losing most of the cytoplasm and some organelles. Immature sperm travel through the seed-forming canals to the epididymis, where they are definitively matured. This whole process takes about 72 days.
