Which statement accurately describes the energy needs for cellular respiration and photosynthesis?

Cross section of different areas of the same plant show cells with very different structure. What does this tell you about the d

BaLLatris [955]

Explanation:

-these are likely different tissue systems or organs

-they each may execute different specified functions

Cells sharing a similar origin, group together in the body to form tissues; these typically share physical features and are arranged in regular patterns. All living things, grow, respire, reproduce etc. these processes are carried out by cells, which are thus integral to their survival.

Further Explanation:

These tissues form systems that may be

meristematic- temporary, found at growth regions called meristems; they are undifferentiated or incompletely differentiated and continuously undergo growth and division
non meristematic- permanent tissue, already differentiated and are made up of plant tissue that no longer divides

Meristems differentiate into three main plant tissue types, which make up several tissues in various amounts:

ground
dermal
vascular tissues

Secondary tissue types are either complex, made up of several different call types, or simple, made up of the same cell type. Dermal tissue covers the plant's outermost layer, and mediates gaseous exchange. While two types of complex vascular tissue, are the xylem and phloem.

Xylem vessel elements: mature xylem vessel is made up of dead cells called vessel elements aligned end-to-end where these ends have been dissolved and the protoplasm is absent. These form long, continuous tubes that facilitate the unobstructed flow of water and minerals to other areas within the plant.

You are observing a sample of cells in the lab to determine why they did not divide properly. You notice that the chromosomes ar

Mandarinka [93]

Answer:

The kinetochore of the chromosomes

Explanation:

<em>What could be damaged that is hindering the spindle fibers from attaching to the chromosomes are the kinetochores of the chromosomes.</em>

At the metaphase stage of the cell division, the chromosomes align at the equator of the cell and the spindle fibers engage each chromosome at a region known as the kinetochore.

The kinetochore is made up of complex proteins and lies around the centromere region of the chromosome. The microtubules of the spindle fibers attach to this region during the metaphase stage.

<u>If the kinetochore is damaged, it means the spindle fiber will not be able to attach to the chromosome. </u>

What two substances are indicated by the cobalt chloride and the lime water tests? is it possible that other substances are prod

shutvik [7]

The cobalt chloride and lime water test is a test to identify the products of combustion.

Two substances that are indicated by the cobalt chloride and lime water tests are water and carbon dioxide. In this test, the clear lime water turns milky that proves the presence of carbon dioxide. The blue cobalt chloride paper turns pink that proves the presence of water.

No, it is not possible to produce any other substances while burning a candle in this test. When the candle is burning, the substances produced are carbon dioxide and water.

As the territory of Africanized bees continues to expand, what is the most likely outcome?

dalvyx [7]

Answer:

Competition among nectar- and pollen-feeding invertebrate pollinators and resource partitioning are affected by introduced Africanized Honey Bees. When Africanized Honey Bees compete with other species of honey bees for flowers, the Africanized bees may displace the other bees from the food sources.

Three human disorders−−fragile X syndrome, myotonic dystrophy, and Huntington's disease−−are conceptually linked by a common mod

Fed [463]

Answer:

The correct answer is ''All three are caused by disparate genes, but each gene was found to contain repeats of a unique trinucleotide sequence.''

Explanation:

Four groups of trinucleotide repeats related to DNA expansion have been characterized in the human genome. CGGI GCC, CAGIGTC, CTGIGAC and recently GW CTT sequences. The CGGl GCC sequences are usually located in the noncoding regions of different genes and when expanded they associate with fragile sites on the chromosomes. The CAGIGTC repeats are part of the coding region and are related to different neurodegenerative disorders. You can try to make a classification depending on the unit that is repeated, having on one side a group that are caused by repeats of the CAG trinucleotide (cytosine, adenine, guanine). Huntington's disease (HD) is a progressive disorder of motor, cognitive and psychic function. The disease is inherited in an autosomal dominant manner, and is caused by the expansion of CAG trinucleotide repeats in exon 1 of the gene called huntingtin (HTT or IT-15). Unstable mutations have also been found in which the repeat unit does not is composed of three nucleotides, if not four, such as type 2 myotonic dystrophy, where the tetranucleotide CCTG repeats. Fragile X Syndrome consists of an abnormal expansion of the cytosine-guanine-guanine trinucleotide (CGG) in the FMR1 gene, which prevents intellectual disability and also influences the formation of connective tissue
