What determines the similarities in anatomical features among organisms?

D) Genes and chromosomes

QUESTION 14

What controls the cell's ultimate production of proteins?

B) DNA

QUESTION 16

What is true about the relationship of DNA and chromosomes?

A) Chromosomes manufacture the proteins that build the DNA molecule.

Chromosomes carry genetic information in a molecule called DNA

QUESTION 18

What role does mRNA play in the delivery of genetic code information?

B) mRNA copies the code from one segment of DNA that represents one gene and then carries it out of the nucleus to a ribosome.

Messenger RNA (mRNA) carries the genetic information copied from DNA in the form of a series of three-basecode “words,” each of which specifies a particular amino acid.

QUESTION 19

A snapping turtle has 52 chromosomes. Which statement correctly compares the number of chromosomes in a body cell with that in a sex cell of a snapping turtle?

A) The body cell has 2n; the sex cell has 1n.

QUESTION 20

Which of these statements is true?

C) Meiosis involves two cycles of cell division.

QUESTION 21

Which phase of cell division includes the pinching off or cleaving of the cell into two new cells?

D) telophase

Telophase refers to the last stage of the mitosis in which the cellular content of the parent cell is divided equally into the two daughter cells.

QUESTION 22

Which statement describes the chromosomes by the end of anaphase of mitosis?

A) The chromosomes reach opposite sides of the cell and begin to be incorporated into two new nuclei.

QUESTION 23

Which phase of cell division results in the formation of four new haploid cells?

D) telophase II

QUESTION 24

Which statement describes the chromosomes by the end of telophase II of meiosis?

D) The chromosomes of each of two diploid cells reach opposite sides of the cell, incorporating into two haploid nuclei.

Which sequence represents the correct levels of organization for multicellular organisms

Anna71 [15]

Multicellular organisms have five levels of organization ranging from simplest to most complex. Level one is cells, level two is tissues, level three is organs, level four is organ systems, and level five is organisms.

I give you brilliant

Alekssandra [29.7K]

Answer:

As soon as the concentration passed 39, the plants died. Adding to that, I have also found out that the lower the concentration of the sugar, the more the average height becomes.

Explanation:

Plant growth and development are tightly controlled in response to environmental conditions that influence the availability of photosynthetic carbon in the form of sucrose. Trehalose-6-phosphate (T6P), the precursor of trehalas in the biosynthetic pathway, is an important signalling metabolite that is involved in the regulation of plant growth and development in response to carbon availability. In addition to the plant’s own pathway for trehalas synthesis, formation of T6P or trehalas by pathogens can result in the reprogramming of plant metabolism and development. Developmental processes that are regulated by T6P range from embryo development to leaf senescence. Some of these processes are regulated in interaction with phytohormones, such as auxin. A key interacting factor of T6P signalling in response to the environment is the protein kinase sucrose non-fermenting related kinase-1 (SnRK1), whose catalytic activity is inhibited by T6P. SnRK1 is most likely involved in the adjustment of metabolism and growth in response to starvation. The transcription factor bZIP11 has recently been identified as a new player in the T6P/SnRK1 regulatory pathway. By inhibiting SnRK1, T6P promotes biosynthetic reactions. This regulation has important consequences for crop production, for example, in the developing wheat grain and during the growth of potato tubers.
