High school biology is in a hurry,,, thank you lalala

1. The function of lysosomes is to break down and engulf damaged or senescent cells and organelles in the cell, and kill viruses or germs that invade the cell (to be carried out) and are selective (controlled by genes). 2. I think so....It is chloroplasts, double membranes that produce oxygen. It is the mitochondria that produce carbon dioxide, which is also a double membrane.

However, cyanobacteria can also photosynthesize to produce oxygen, but there are no chloroplasts, only chlorophyll, so I don't know if I should consider it...3 The nucleus is not an organelle 4 In the thylakoid membrane, it is a photosynthetic pigment that is used to absorb light (the mobile phone is very tiring to play by hand...).Look >

Organelles and cells that can be broken down and damaged will be lysolyzed by lysosomes, so that intact cells will not be dissolved.

Not necessarily, as yeast produces CO2

The nucleus is not an organelle. Organelles are found in the cytoplasm, whereas the cytoplasm (which refers to the part of the cell outside the nucleus within the plasma membrane.

On the thylakoid membrane in chloroplasts. Chloroplasts contain two major groups: green pigments (including chlorophyll a and chlorophyll b) and yellow pigments (including carotene and lutein).

Lysosomes can break down damaged organelles, and cannot hydrolyze their own cells only when the cell has complete life activities, once the cell dies or breaks, the lysosomes will break down useful substances in the cell for use by other cells.

It is not necessarily a double-layer membrane that can produce gas, and oxygen is produced on the thylakoid film in photosynthesis, a monolayer membrane.

Organelles are divided into: mitochondria; Chloroplast; Endoplasmic reticulum; Golgi apparatus; lysosomes; Vacuoles, ribosomes, centrosomes. Among them, chloroplasts and vacuoles are only found in plant cells and lower animal cells, and centrosomes are only found in lower plant cells and animal cells.

Also, the nucleus is not an organelle.

The pigments are distributed on the thylakoid films.

Hope, thank you.

1. Lysosomes include primary lysosomes, secondary lysosomes and residual bodies (or postlysosomes). The size of primary lysosomes is not very different from that of mitochondria. Secondary lysosomes are large and can reach several microns in diameter. The remnants are relatively small.

2. Lysosomes decompose aging and damaged organelles may be similar to cell fusion, and primary lysosomes release enzymes in lysosomes into organelles through fusion with organelles or phagocytosis to form secondary lysosomes and remnants of various sizes and shapes. Remnants can be excluded from the cell by a form similar to exocytosis. During this process, the enzymes of the lysosomes themselves are not easily released into the cytoplasm.

3. If a small amount of lysosomal enzymes are released into the cytoplasm, the impact will not be great, because the optimal pH of most lysosomal enzymes is about 5, and the pH value of most cytoplasmic enzymes is about 7.

Photosynthetic bacteria and cyanobacteria are prokaryotes that do not have a double biofilm, but can produce oxygen and carbon dioxide gas.

The nucleus is not an organelle.

The pigments of chloroplasts are distributed on thylakoid films.

Lysosomes contain hydrolase enzymes that hydrolyze a variety of macromolecular organic matter and are able to break down damaged organelles. It is a process of directed induction.

The second question didn't understand what it meant.

The Zhejiang Science Edition defines the nucleus as the largest organelle in the cell, and the human education version has not been changed.

The pigments of chloroplasts are used in photoreactions and are present on the basal granule, which is the membrane of the endocyst.

OK. The gas that can be produced on a biofilm is not necessarily a double membrane.

The nucleus is not an organelle, on the thylakoid membrane in chloroplasts.

Lysosomes are selective in engulfing senescent and damaged organelles.

It must be a double membrane (I've done it).

The nucleus is not an organelle.

The pigments of chloroplasts are distributed on thylakoid films.

The statement is wrong with a (answer).

Because there are no orthogonal and inverse experiments for the relative trait of the flower in Figure B, it is only a mating method, and it cannot be concluded that it is inherited from nuclear genes.

Hemoglobin is inside red blood cells.

Plasma proteins are free in the blood plasma.

Blood: Composed of plasma and blood cells.

Plasma: Blood that does not contain cellular components.

Serum: The fluid released by the condensation of blood clots after the blood clotting in isolation, that is, serum. Roughly speaking, the difference between serum and plasma is mainly that serum does not contain fibrinogen.

Blood: 1 blood cell (red blood cells have hemoglobin).

2 Plasma: 1 plasma protein 2 serum.

Question 1 is selected b

aHemoglobin synthesized by young red blood cells is not secreted, but remains in red blood cells, so the Golgi apparatus is not needed.

c. The totipotency of hematopoietic stem cells is greater than that of young erythrocytes.

dTheir amino acid composition is similar, but the amino acid composition of the key sites is different.

The second question selects the generation of cells of the genotype Ca and B, which is produced by the absence of homologous chromosomes at the time of minus, and does not belong to genetic recombination.

Men with normal D phenotype may also carry the A gene, so the probability of albinism is not zero.

1: The first question please turn to the high school biology textbook elective book, continuous culture of bacteria 2: There are three kinds of genetic mutations, chromosomal variations, and genetic recombination for heritable variations, because bacteria do not have chromosomes, all of them cannot carry out the last two items, only gene mutations.

3: Fermentation has a broad and narrow sense, if you are a Chongqing candidate is not required to master, if not, please read the high school biology textbook elective fermentation project.

4: It can be understood in this way, bacteria are prokaryotes, plants are eukaryotes, the same result is only cell wall ribosomes, and the antigenicity, pathogenicity and sensitivity to phages of bacteria are related to the cell wall of bacteria, so it can only be the cell wall.

5: The definition field is different, and the second obvious x cannot be 0

Your ** is so hard to see, are you this question? We're also taking the test.

The molecular formula of glucose is C6H12O6 and the molecular formula of the polymer formed by the dehydration condensation of 100 glucose molecules as monomers is (C).

Characteristics of the process of condensation of glucose monomers to form polymers.

See Answer Process.

Analysis: When the two molecules of glucose are condensed, one molecule of water is removed, and when the N molecule glucose monomer is condensed into a polymer, (N 1) molecular water is removed, so when 100 glucose molecules are condensed, (100 1) molecule water is removed, and the molecular formula of water is H2O, so when a polymer is formed.

The removed h is (100 1) 2=198, the removed o is (100 1) 1=99, the molecular formula c of the multimer is 6 100=600, h is 12 100 198=1002, and the o is 6 100 99=501, so the molecular formula of the multimer is c600h1002o501. Answer: C ...

This question is so simple, choose C, why, because a glucose is C6H12O6, 100 dehydration condensation (will lose H2O, that is, less H element and O element) is C600, the number of H is 12 times 100 — 2 (every time one water is removed, two H will be removed) times 99 (a total of 99 water removed, why? Wait for the first o is 6 times 100 — 1 (for each water removed, an o is removed) times 99So choose C

Anyway, you remember, the number of amino acids - the number of peptide chains = the number of peptide bonds = the number of water molecules removed, in this topic, it is 100 — 1 (because the title says "polymers", no special instructions, it is a peptide chain) = 99 (water"h2o"）
