『三』 How many eggs can the bird's tail mantis shrimp lay at one time?

The bird's tail mantis shrimp can reproduce throughout the year, reaching its peak in the warmer months. Eggs are laid at night. Normally, shrimp eggs are carried in large numbers by females, who take care of their eggs untilto hatch.
The details of mantis shrimp mating, egg laying, and hatching in caves are difficult to observe. The sparrow-tailed mantis shrimp is usually monogamous;
It is an arthropod of the class Softshell and the family Odontodactyidae. The body length can reach up to 18 cm, and the appearance is very bright, consisting of red, blue, green and other colors. It is a carnivorous arthropod with a color similar to that of a peacock. The scales of the tentacles are orange-red, with black outer edges at the ends. The front edge of the head and breastplate has black and brown honeycomb patterns with white edges. The large chela hook on the chest has great popping power and can swing out its stick-like shape in an instant. The front pincers smash into the prey.
Benthic life, often inhabiting coral reef crevices and caves, can also live on the bottom of gravel or shells. It is carnivorous and mainly preys on slow-moving gastropods, bivalves, and crustaceans at the bottom of the ocean. When raised in captivity, it can be fed fish, shrimp and other animal foods.
The second pair of mandibular legs of the bird-tailed mantis shrimp is very developed, which is its weapon for hunting and defending against enemies. The front end of its catching limb is in the shape of a single thorn, the end is very sharp like an awl, and the root is convex and thickened. When it is folded, the thickened part can break the hard shells of crustaceans, shellfish, snails and other animals like a hammer; and when it is extended, it can easily pierce the soft tissue of animals. [4]
The reason why it is called "bird-tailed mantis shrimp" is not only that it looks like a peacock, but also that the way it hunts is like a mantis. After tens of millions of years of evolution, the predatory limbs (second pair of mandibular legs) of the sparrow-tailed mantis shrimp have evolved into a pair of powerful "spring iron fists." When prey approaches, it uses its pair of elastic front claw hooks to knock the prey hard, and more than once, the bird-tailed mantis shrimp will pursue it more depending on the situation. It is a very smart carnivore. , just like a boxer using a jab to attack his opponent quickly, but the jab of the mantis shrimp is more powerful and faster.

『四』Is Shanghai Telecom’s data card enough for a family?

Recently, a video on the Chinese government website hit the screen, talking about the benefits achieved by “increasing speeds and reducing fees” Phased results. Every mention and every drop is not only a "red envelope" to the people, but is also of great significance to the transformation and upgrading of the national economy.

2017 is the first year of “unlimited quantity” in China. In other words, communication traffic is no longer so valuable! Along with this, lower and lower tariff prices are quietly changing the Internet environment around us.

In Beijing, Shanghai and Guangzhou, which has the highest consumption level in my country, it is roughly estimated that as long as a family spends about US$30 per month, they can enjoy almost the fastest broadband and mobile phone network speeds in the world, and both are " Unlimited”.

The cost for everyone to connect to the Internet has been minimized and is getting lower.

Since the second half of last year, the focus of competition among telecom operators has been on “unlimited traffic”. In Shanghai, a family of five can enjoy sufficient data as long as they spend 199 yuan. More mobile data, 50Broadband above 0M and 4K HD IPTV.

In some other provinces and cities, some operators have launched "unlimited traffic within the province for 99 yuan", and have launched unlimited packages as low as 49 yuan or even 29 yuan for some key group corporate customers. .

This is not over yet. Starting from 2018, traffic rates are still lowering in various forms. Various packages and marketing activities such as "10 yuan for unlimited traffic in the province" and "1 yuan for 1GB" have made The traffic fee is so low that even Internet companies can’t understand it.

Don’t let go of every user and serve every user well. The three major operators are engaged in almost the last round of incremental competition for increasingly scarce user resources in the market. When every user has a mobile phone, and even the two card slots in the mobile phone are full, the operators will Forget it.

If you are a die-hard user of a certain operator, just participating in various marketing activities through the operator’s WeChat official account, website, etc., and getting free traffic will be enough for you to enjoy it for a long time. .

There is no doubt that communication traffic is entering the "GB" era, and the "M" traffic unit is gradually becoming a thing of the past. At the same time, it is almost certain that China is the most active country in promoting 5G and will also be one of the first countries to launch 5G commercialization. A new battlefield for communication consumption upgrade is beginning.

Compared with small places such as Japan and South Korea, China's three major operators have completed high-quality coverage of 9.6 million square kilometers of land, and the coverage of high-speed mobile communication networks and broadband far exceeds that of the United States and other countries. Big country. It is reported that this year, the Ministry of Industry and Information Technology will promote the elimination of traffic roaming fees, which is the highlight of the Ministry of Industry and Information Technology’s 2018 “speed increase and fee reduction” work.

In May 2015, the Prime Minister proactively proposed specific measures to "increase speeds and reduce fees" at the executive meeting of the State Council. In the past three years since then, telecom operators have achieved visible results on the consumer side. "speed up" and "fee reduction".

It can be said that under the wave of "fee reduction" and the expectation of "speed increase" due to the popularization of Gigabit and the imminent 5G, at this stage, the main contradiction faced by the development of the Internet and all related industries is no longer It is the contradiction between the growing demand for a rich and colorful Internet life among netizens and the backward Internet speed and high Internet tariffs.

The information superhighway is already in place, and the charges are not expensive at all; consumers of digital life are ready. It depends on what kind of consumption upgrade corporate innovators plan to provide them.

To get rich, you must first build roads. Rapid economic development is inseparable from the efficient allocation and transmission of all production resources and productivity. Where is the next broad road leading to the entrance of the village and the doorsteps of people's homes? Perhaps hidden in the optical fibers and base stations, the Internet and mobile Internet world connected by wired and wireless communications, there is almost no suspense that it will become one of the most important parts of the future world, productionResources, information flows, etc. are freely transmitted here. If "increasing speed and reducing fees" can reduce the cost of information transmission in the information world and improve the utilization efficiency of networks, data, etc., then it is equivalent to pressing the "start" button for the economy to take off again.

Therefore, operators are already close to completing the "speed increase and fee reduction" on the consumer side to a certain extent. In the future, operators should focus on the "speed increase and fee reduction" on the industrial side to make information networks better. It can effectively serve manufacturing and Internet innovation, making entrepreneurship and innovation more cost-effective. If the Internet speed and tariff coefficient of Chinese people already have considerable advantages in global horizontal comparisons, then the next step will be the turn of Chinese companies to enjoy such benefits.

At the same time, for the three major operators, the huge enterprise market is also a fertile land that needs to be cultivated. Cloud computing, the Internet of Things, big data, and the Internet of Vehicles all have huge room for imagination. The incremental market is the core direction for the business transformation and capability upgrading of the three major operators.

So, if there is still a second half to “increasing speeds and reducing fees”, then please launch it in the big blue ocean of the enterprise market. This is because what increases speed "increases" the competitiveness of enterprises, while reducing fees "reduces" total social costs.
