Answer:

i think true water-conducting tissue is a derived character of green algae?

Explanation:

WHY?

Many characteristics of land plants also appear in algae like both are multi cellular, euks, photosynthetic autotrophs so are brown, red, and certain green algae, plants have cell walls made of cellulose and so do green algae

However, charophytes are the only present day algae that share these traits with land plants

1.Rings of cellulose-synthesizing proteins (circular rings of proteins in plasma membrane that make cellulose of cell wall)

2.Structure of flagellated sperm

3.Formation of a phragmoplast ( group of microtubules known as phragmoplast formes b/t daughter nuclei of a dividing cell, giving rise to a cell plate making cross wall that separates the daughter cells)

Comparisons of both nuclear and chloroplast genes point to charophytes as the closest living relatives of land plants

Land plants are not descended from modern charophytes, but share a common ancestor with modern charophytes

WHY NOT?

The origin of embryophytes, as these multicellular plants arose and conquered the land, was a pivotal event in the history of life on earth. Without embryophytes, there would be no animals or humans surviving on the land portion of our planet. The provide food, habitat, energy, oxygen, protection, and numerous vital other functions for the world's creatures. Human beings also benefit from the aesthetic beauty, medicines, and innumerable products derived from these diverse plants.

Calculate the average rate of change in corn yield from 1964 to 2008 (Round to the nearest whole number.)
Anna11 [10]

Answer:

In 1964 2.6 bales per hectare while in 2008, 380 bushels per hectare.

Explanation:

in 1964, the average corn yield was 2.6 bales per hectare which is equals to 570 kg per hectare while in 2008, the average yield of corn was 380 bushels per hectare which is equals to 9655 kg per hectare. This increase in the productivity of corn crop is due to advancement of technology, high yielding seed varieties and reduces post harvest losses. The yield of 2008 is 17 times higher than 1964.

zvonat [6]

Answer;

-No more; no more

Compared with fraternal twins, identical twins are no more similar in physical appearance. Compared with unrelated look-alike pairs of individuals, identical twins report no more similar personalities.

Explanation;

-Compared with fraternal twins, identical twins are much more similar in extraversion, neuroticism and temperament.

-Since fraternal twins are 2 separate fertilized eggs, they usually develop two separate amniotic sacs, placentas, and supporting structures. Identical, or monozygotic, twins may or may not share the same amniotic sac, depending on how early the single fertilized egg divides into two.

Each of 100 laboratory rats has available both plain water and a mixture of water and caffeine in their cages. After 24 hours, t
olchik [2.2K]

Answer:

C. About 18 percent of the variation in blood pressure can be explained by a linear relationship between blood pressure and caffeine consumed.

Explanation:

Here, r = 0.428

∴ We can say it will give a positive curve, as 0.428 indicates it is a positive correlation.

Though the amount of correlation is low, still it is positive and more than 0.4

So, nearly about 18% of the variation in the blood pressure can be observed by the consumption of caffeine water. As consumption of caffeine water and blood pressure is both increasing so we can say that r= 0.428 will give a positive linear curve.
