Which structures of this organism work together to carry out all of its life
functions?
Answer:
nucleus
Explanation:
Substance A and substance B are mixed together. To separate the mixture, water is added, and substance A is filtered out. Then, the remaining liquid is heated to remove the water, leaving a residue of substance B. Which statement about substance A and substance B could be correct?
Substance A is rice, and substance B is sugar.
Substance A is rice, and substance B is sugar.
Substance A is sugar, and substance B is instant coffee.
Substance A is sugar, and substance B is instant coffee.
Substance A is sand, and substance B is alcohol.
Substance A is sand, and substance B is alcohol.
Substance A is alcohol, and substance B is salt.
The correct answer would be that substance A is rice, and substance B is sugar.
For substance A to be filtered out, it means that A is a water-insoluble substance and for substance B to be recoverable by evaporating off the water, it means that B is water-soluble.
Thus, A can neither be sugar nor alcohol because neither can be recovered by filtration. Also, B can neither be coffee nor alcohol because they can not be recovered as residue through evaporation of water.
Therefore, the only correct answer is that substance A is rice, and substance B is sugar because rice can be filtered out from water while the water-soluble sugar can be recovered by evaporating the water.

If eukaryotes all came about due to endosymbiosis, what would result from that?
Endosymbiosis occurs when larger prokaryotes envelop prokaryotes that perform aerobic metabolism (later known as mitochondria) and prokaryotic cells that do photosynthesis.
These "now" mitochondrion's "came to realise" that they really can not live without the bigger prokaryotes that swallowed them, and therefore they stayed with them.

Explanation:
i hope it helps you
The DNA stands for deoxyribose nucleic acid, it has all the information required for the proper functioning of the human body.
The correct answer is B
The process of the formation of protein from the mRNA is called translation. it requires:-
RibosometRNAmRNAThe mRNA has the introns and the exons in it. Exons are the coding part of the DNA while the introns are the non-coding part and it does not have any specific functions.
Hence, the correct option is B that is Introns do not have any specific function.

In an experiment to investigate a factor affecting photosynthesis, a leaf of a potted plant which had been kept in the dark overnight was covered with aluminum foil as shown in the diagram below 1. Aluminium foil The set up was kept in sunlight for three hours after which a food test was carried out on the leaf. (a) Which factor was being investigated in the experiment? b) What food test was carried out? (i) State the results of the food test (ii) Account for the results in c (i) above
Answer:
Photosynthetic activity.
Explanation:
The photosynthetic activity of the plant was being investigated in the experiment and no photosynthesis will occur because the aluminium foil reflect 95% of sunlight. Starch test is the food test that was carried out in the experiment. Starch from plants is broken down into its constituent sugar molecules by the plant body in order to provide energy to the tissues so if there is no photosynthesis occurs, the plant body uses starch so decrease occur in the concentration of the starch molecules when the starch food test will occur.

It is possible to know their genotypesthe shapes should be shaded as wellExplanation:
It is possible to know the genotypes of the Children ( three of them ) and their genotypes are ; Hh, Hh, Hh
Their shapes should be shaded as well and this because the (3) children posses the dominant allele H in their genotype composition .
Some records associated with your query is lacking connection underneath are the records.
It is feasible to recognize that their genotypes shapes have to be shaded as properly.

Which of the following is not true of integrin? Question 4 options: Integrin molecules serve as stable, permanent anchors that anchor a cell to the extracellular matrix. Integrins undergo extensive conformational changes on binding to molecules on either side of the plasma membrane. Certain intracellular chemical signals can activate integrins from inside the cell, causing them to reach out and grab hold of extracellular structures. When integrin binds to the extracellular matrix, it stretches into an extended, activated state to attach to molecules on the inside of the cell.
Answer:
Integrin molecules serve as stable, permanent anchors that anchor a cell to the extracellular matrix.
Explanation:
Integrins are transmembrane protein receptors that attach the cell cytoskeleton to the extracellular matrix (ECM) in animal cells. These glycoproteins (integrins) are highly dynamic heterodimeric molecules that anchor cells in their position and transduce signals into and out of cells. Integrin-ligand binding activates signaling pathways that are involved in fundamental cellular functions including, among others, organization of the cell cytoskeleton, cell migration, regulation of the cell cycle, etc.
The statement i.e. not true is Integrin molecules serve as stable, permanent anchors that anchor a cell to the extracellular matrix.
The following information should be considered:
