Which of the following is characteristic of gymnosperms?

1 answer:

7 0

The name gymnosperm means "naked seed," which is the major distinguishing factor between gymnosperms and angiosperms, the two distinct subgroups of seed plants. This term comes from the fact that the ovules and seeds of gymnosperms develop on the scales of cones rather than in enclosed chambers called ovaries.

What is the primary function of the endocrine system

harkovskaia [24]

Answer:

To maintain body homeostasis

Explanation:

The endocrine system consists of the endocrine glands that release hormones directly int the blood. Those hormones bind to their receptors on the target cells and thus regulate their function. The major glands are:

pineal gland-releases melatonin, controls sleep cycle

pituitary gland-control growth, blood pressure, thyroid glands and metabolism etc.

pancreas-secretes insulin and glucagon, control of blood sugar levels

ovaries, testes-reproductive role (release female and male hormones)

thyroid gland-controls metabolism and protein synthesis

parathyroid gland-controls Ca levels

hypothalamus-connects nervous and endocrine systems, controls other glands

adrenal glands-release adrenalin and steroid hormones.

Three lots with parallel side boundaries extend from the avenue to the boulevard as shown answer

larisa86 [58]

Three lots with parallel side boundaries extend from the avenue to the boulevard as shown in the diagram attached.

Given;
x + y + z = 140 meters

According to the proportion theorem,

$\frac{x}{40} = \frac{y}{30}$

Solving for x, using cross multiplication:

$\frac{x}{1} = \frac{40y}{30}$

Similarly,

x/40 = z/35

solving for z by cross multiplication,

z = 35x/40
z = 7x/8

Now, the third proportions,
y/30 = z/35

Solving for y,

y = 30z/35
y = 6z/7

x + y + z = 140

4y/3 + 6z/7 + 7x/8 = 140

(224y + 144z + 147x)/168 = 140

224y + 144z + 147x = 23520

Substitutoing z = 7x/8,

224y + (144 × 7x/8) + 147x = 23520

224y + 126x + 147x = 23520

224y + 273x = 23520
Now,
Substitute y = 3x/4

(224×3x/4) + 273x = 23520

168x + 273x = 23520

441x = 23520

x = 53.33

Now,
We know that
y = 3x/4
so,
y = 40

And,
z = 7x/8
Z = 46.66
