If f (5x + 8) = 3x + 2, find (6)

If f (5x + 8) = 3x + 2, find (6)

Let (5x + 8) = (6) get x = - 2 / 5, and take x = - 2 / 5 into 3x + 2 to get f (6) = 4 / 5

How to solve 5x-8 = 3x + 2?
There's another one: 4 × (x - two thirds) = one fifth

5x-8=3x+2
5x-3x=2+8
2x=10
x=5

How to solve 3x-7 = 2.5x-3.4

3x－7＝2．5x－3．4
3x-2.5x=7-3.4
0.5x=3.6
x=7.2

How to solve (5x-90) * 3 = (3x 90) * 2

(5x-90)*3=(3x+90)*2
15x-270=6x+180
15x-6x=270+180
9x=450
x=450÷9
x=50

How many pathways are there for the formation of effector B cells in organisms

1. After phagocytosis, the antigen was presented to B cells by T cells
2. Antigen directly stimulates B cells to proliferate and differentiate into effector B cells
3. After antigen entry, memory cells were stimulated to proliferate and differentiate into effector B cells

What are the continuous dividing cells in organisms? What are the animal cells? What are the plant cells?

Poorly differentiated: hematopoietic stem cells neural stem cells spermatogonia undifferentiated: embryonic stem cells
Plant: seed (embryo) root meristem cell bud

There are some mistakes in the following understanding of substances or cells in organisms ()
A. Restriction enzyme, tRNA, antibody, receptor, carrier and memory cell all have specific recognition function. B. starch and fat of the same quality are oxidized and decomposed respectively, and the oxygen consumption of starch is lower than that of fat. C. Penicillium and Diplococcus pneumoniae can carry out aerobic respiration, and heredity follows Mendel's law. D. effector T cells can induce apoptosis of target cells by contacting with target cells

A. Restriction enzyme, tRNA, antibody, receptor, carrier and memory cell all have specific recognition function, a is correct; B, the proportion of C and h in fat is higher than the same quality of sugar, so the same quality of starch and fat are oxidized and decomposed respectively, the oxygen consumption of starch is lower than that of fat, B is correct; C, Penicillium, Diplococcus pneumoniae are all

In biology, autotrophic bacteria belong to producers. Do they have chloroplasts in their bodies?

This is not necessarily. In high school biology, there are the following situations: 1. In autotrophs, eukaryotes generally have chloroplasts. 2. Prokaryotes have only one organelle: ribosome, so there is no chloroplast, but they can carry out photosynthesis because they have chlorophyll in their bodies. 3. There is a special kind of bacteria, called nitrifier

Is there any living thing below 10000 meters!
I'd like to know

A microbial kingdom was discovered in the 10000 meter deep sea by Japan and Britain

_____________________________________________________________
During the exploration of the 10 000 meter deep Mariana Trench, the Japanese ocean research and Development Institute and the Southampton Institute of Oceanography have for the first time isolated the crusted marine unicellular foraminifera from the surface sediments of the seabed
The average number of foraminifera isolated from the surface sediments is 449 per square centimeter. More than 85% of the foraminifera are long and thin bag shaped and have soft shell. They are all new species not recorded in taxonomy, The newly discovered crustacean foraminifera and the common crustacean species in the ocean took two evolutionary paths about 800 to 1 billion years ago, which can be called living fossils on the sea floor. The results are published in the American Journal of science today
Deep sea bottom is the extreme environment of darkness, low temperature, high pressure and extreme lack of nutrition. Like space, it is difficult for human beings to reach it. Scientists have always believed that marine organisms have undergone great changes after differentiation in shallow sea, and there are many species that still maintain ancient characteristics in deep sea bottom. Therefore, we hope to observe the dynamics of sediments and water boundary in deep sea bottom, The research results show that there are foraminifera in the deepest ocean of the world, which went to different evolutionary paths from 800 to 1 billion years ago. This conclusion supports the above theory
It is generally believed that the biota living in the trench is an ecosystem mainly relying on photosynthesis. However, due to the lack of food in the deep sea, eukaryotes living in this extreme environment may coexist with bacteria to absorb nutrients, Through genetic gene analysis and histological study with electron microscope, we can understand the environmental adaptation mechanism of organisms in the extreme environment of deep sea and the physiological structure of symbiosis with bacteria, which is of positive significance to the discovery of functional genetic genes
Due to the existence of various shapes of trenches in the deep sea, recent research indicates that there are different kinds of biological groups in different trenches. This research can understand the generation of trenches and the evolution of trench biological groups, and can fill the gap in the history of life development. (Chen Chao)

Mariana Trench
The Mariana Trench is the deepest trench in the world's Shanghai Ocean. The deepest part of the Mariana Trench is called the Challenger abyss, Its name is in memory of the British ship "Challenger 8" who discovered it. How deep is the Challenger abyss? In 1951, the Challenger 8 detected a depth of 10836 meters; in 1957, the Soviet Union's Vityaz measured a depth of 11034 meters by using acoustic reflectors; in 1960, the US manned submersible "riaster" successfully reached the Challenger abyss The depth measured by plumb is 10912m; the depth measured by Japanese ship takuyo in 1984 is 10924m; the depth measured by Japanese submarine Haigou in March 1995 is 10911.4m（
