Which of these body systems works most directly with the digestive system in the absorption of nutrients?
A) urinary system
B) endocrine system
C) respiratory system
D) cardiovascular system
Answer:
D

PlLEASE HELP ME> I NEED THIS ANSWER RIGHT NOW. The bass and crayfish likely “died off” because the rapid growth of the algae eventually caused the level of dissolved oxygen to decline to a point that these oxygen-dependent organisms could no longer survive. How would you modify this investigation of the pond organisms to determine if the algal bloom really was the cause of the bass and crayfish die-offs?
Answer:
bacteria blooms and decreased underwater photosynthesis causes hypoxia, killing the fish. c. floating algae die, increasing sunlight penetration and heating the water. ... This has led to algal blooms in the pond which periodically reduce the amount of dissolved oxygen available in the water

all plant bodies(root,stem and leaf) are externally covered by epidermis but why woody plant is covered by barks
Answer:
Bark comprises all the tissues surrounding the xylem in woody plants. Broadly, bark includes an inner and mostly living region and an outer, dead one. Of all plant structures, bark has the most complex anatomical structure and ontogenetic origin involving two (and often three) different meristems.
As to why, the bark adds layers to the inside ring of the vascular cambium, the outside is pushed outward. The cells die off, and the fibrous matrix of cellulose and lignin molecules remain. This hard structure forms the bark, and protects the tree or plant from many forms of damage.
What would happen to zygote if the egg and sprem cells weren't formed with the correct number of chromosomes?

The fifth grade craft club is making aprone to sell
Each apron take 1.25 yards of fabrie that costs $3
per yard and 4.5 yards of trim that costs $2 per yard,
What does it cost the club to make one apren? If the
club wants to make $1.75 profit on each apron how
much should they charge per apron?
Answer:
Each apron costs $ 12.75, and to make a profit of $ 1.75 they should be sold for $ 14.50.
Explanation:
Since the fifth grade craft club is making aprons to sell, and each apron take 1.25 yards of fabric that costs $ 3 per yard and 4.5 yards of trim that costs $ 2 per yard, to determine what does it cost the club to make one apron, and, if the club wants to make $ 1.75 profit on each apron, how much should they charge per apron, the following calculations must be performed:
1 apron = 1.25 yards of fabric at $ 3 per yard and 4.5 yards of trim at $ 2 per yard
1.25 x 3 + 4.5 x 2 = X
3.75 + 9 = X
12.75 = X
12.75 + 1.75 = 14.50
Therefore, each apron costs $ 12.75, and to make a profit of $ 1.75 they should be sold for $ 14.50.
