Which pair of statements most accurately describes Earth's position relative to
the sun in late March and in late September?
Answer:
A
Explanation:
According to the text, which amino acid(s) contains a side chain..
a. in which molecules form covalent disulfide bridges with each other?
b. that is hydrophobic?
c. that forms hydrogen bonds?
d. that is basic?
Answer:
(b) that is hydrophobic
Explanation:
e.g, alanine
Cause, Alanine possess hydrophobic side chain and the most appropriate answer is (d) part......
Alanine is an aliphatic amino acid, because the side-chain connected to the α-carbon atom is a methyl group (-CH3), alanine is the simplest α-amino acid after glycine. The methyl side-chain of alanine is non-reactive and is therefore hardly ever directly involved in protein function..
Hope it will help you☺☺☺☺☺

How do the physical and chemical properties of wood contribute to the function of the synthetic products made of wood?
Wood's tensile strength is reduced. Another risk factor for the strength of the wood is the loading time. The rigidity of wood is affected by temperature.
What is wood?Wood is one of the most common and useful natural materials. It is the main tissue that supports and conducts nutrients in trees and other plants. Wood comes in a variety of colours & grain patterns and is produced by numerous botanical species, comprising both gymnosperms & angiosperms.
Its wood's tensile strength is reduced. Another risk factor for the strength of the wood is the loading time. The rigidity of wood is affected by temperature. Unfavourable weather and unexpected temperatures will have an impact on the wood's strength. Among its attributes are mechanical, chemical, and physical qualities.
Therefore, wood's tensile strength is reduced. Another risk factor for the strength of the wood is the loading time.

Li + N2
Li3N
Answer:
Combination or synthesis
Explanation:
The given reaction is:
6Li + N₂ → 2 Li₃N
This reaction is a synthesis or combination reaction. 6 moles of Li combines with nitrogen gas to produce 2 moles of Li₃N.
In a synthesis reaction, two substances combines together to give singular product. The formation of compounds from the union of the constituent elements falls into this category of reaction.What is the lon # for Beryllium (Be)?

A pharmacist mixed some 10%-saline solution with some 15%-saline solution obtain 100 mL of a 12%-saline solution. How much of the 10-saline solution did the pharmacist use in the mixture
Answer:
10%-saline solution = 60mL
15%-saline solution = 40mL
Explanation:
Let
10%-saline solution = x
15%-saline solution = y
x + y = 100
0.1x + 0.15y = 100*0.12
x + y = 100 (1)
0.1x + 0.15y = 12 (2)
from (1)
x = 100 - y
Substitute x = 100 - y into
0.1x + 0.15y = 12
0.1(100 - y) + 0.15y = 12
10 - 0.1y + 0.15y = 12
- 0.1y + 0.15y = 12 - 10
0.05y = 2
y = 2 / 0.05
y = 40mL
Substitute y = 40 into
x + y = 100
x + 40 = 100
x = 100 - 40
x = 60mL
10%-saline solution = 60mL
15%-saline solution = 40mL
