Answer:

1) alternate, opposite and whorled

2) the primary functions Of the stem are to support the leafs to conduct water and minerals to leafs, where they can be converted into usable products by photosynthesis

3) stesms stores food, water, and nutrients. cells of steam , meristems, produce new living tissues. underground stem, aerial stem and subaerial steam are three different stem

4) the are six elements 1 nodes 2 internodes 3 terminal or apical bud 4 lateral or axillary bud 5 petiole 6 pedecel. while the two organd are 7 leaves and 8 flowers

5) roots = in botany that parts of vascular plant normally underground FUNCTIONS are anchorage of plant absorption of water and dissolved minerals and conditions of these to stem, and storage of reserve foods

In what two ways are active transport proteins similar to enzymes

Ksju [112]

They change conformation/shape when the right molecule bind in their active site.
They enable reactions to proceed ‘downhill’. For enzyme, when the reactants are more than the products, the reaction proceeds to the right of the reaction. Career proteins also carry molecules down their concentration gradient.
Both career proteins and enzymes are not denatured during the process of their biological activity

A steel bar has a mass of 4,000 kilograms and a volume of 0.5 cubic meters . Calculate its density. Write your answer as a whole

mixer [17]

The equation for density is:

$D=\frac{m}{V}$

where the mass is in grams and the volume is in $cm^{3}$ .

We are given 4,000 kilograms, and we know that there are 1,000 grams in 1 kilogram, so we need to multiply to convert to grams:

$4,000*1,000=4,000,000g$

We are also given 0.5 $m^{3}$ , and we need to convert to $cm^{3}$ . We know that there are 100 cm in 1 m, and since we are talking about cubic volume, we must also raise 100 to the 3rd power: $100^{3}=1,000,000cm$ . So now we know that there are 1,000,000 $cm^{3}$ in 1 $m^{3}$ . We need to then multiply 1,000,000 cm by 0.5 in order to find the volume that was given in the question:

$1,000,000*0.5=500,000cm^{3}$

So now that we have the correct units, let's plug them into the equation:

$D=\frac{4,000,000g}{500,000cm^{3}}$

$D=\frac{8g}{cm^{3}}$

So now we know that the density is 8g/cubic centimeter.

How does the study of the time progression of fossils support the process of evolution?

Airida [17]

Answer:

Thanks to the fossil record, direct evidence of the evolution and change of species can be given over the years. The fossil record tells us the natural history of the species in the different geological ages and allows us to see the changes in the distributions of the species, extinction and diversification from comparison and measurement.
