Polymers are made of monomers, and both are kinda of compounds? True or false
Answer:
true
Explanation:
i am not sure but i hope it will help you
True, polymers are made of monomers, and both are kinds of compounds
Explanation:
A polymer is a long chain composed of several monomer units which are chemically combined together. Or polymer is a material or substance made up of repeating units called a monomer.The monomer is a simple repeating unit in a polymer. When the several small monomer units combine with each other via a chemical reaction and give out a large chain-like molecule this process is called polymerization.So from this, we can conclude that polymers are made of monomers, and both are kinds of compounds

Answer:
[tex]\huge\mathfrak\pink{ur}\huge\fbox\green{answer}[/tex]
The hydrogen bond is one of the strongest intermolecular attractions,
A single hydrogen atom can participate in two hydrogen bonds, rather than one. This type of bonding is called "bifurcated" (split in two or "two-forked"). It can exist, for instance, in complex natural or synthetic organic moleculesAnswer:

We usually get some questions about how many hydrogen bonds these compounds can create, we use it to differentiate between the boiling point of each one of them so it would be great if you could help me.
So what I know that H2O has 4 hydrogen bonds those are 2 from hydrogen atoms and 2 from other molecules that has 2 hydrogen atoms connected to the 2 lone pair of electron that the oxygen has.
In HF, It has 2 hydrogen bonds. The same explanation implies here. In NH3, 2 hydrogen bonds because N doesn't have the required amount of lone pairs to make more hydrogen bonds.

Dihybrid cross experiments led Mendel to propose his law of independent assortment.
Which statement best describes this law?
A. The law of independent assortment states that alleles of different genes are inherited together.
B. The law of independent assortment states that when two inherited alleles are heterozygous, the dominant allele is the one that is expressed.
C. The law of independent assortment states that alleles of different genes are inherited independently of each other.
D. The law of independent assortment states that alleles are separated when gametes form, causing gametes to carry only one allele for each gene.
Answer:
c
Explanation:
The answer is c: The law of independent assortment states that alleles of different genes are inherited independently of each other.
According to Mendel's law of independent assortment, the alleles of two or more distinct genes are sorted into gametes in a manner that is independent of one another. The allele a gamete acquires for one gene does not affect the allele a gamete receives for another gene, in other words. Thus, option C is correct.
What Mendel propose his law of independent assortment?According to Gregor Mendel's law of independent assortment, genes are inherited independently of one another. Due to the fact that two genes are found on the same chromosome, linked genes constitute an exception to the rule of independent assortment; however, this effect is usually lessened when chromosomes cross over.
According to Mendel's law of independent assortment, the alleles of two or more distinct genes are independently selected into gametes. In other words, an allele for one gene does not impact the allele for another gene that a gamete acquires.
Therefore, The law of independent assortment states that alleles of different genes are inherited independently of each other.

satellites will be forced to Earth's surface
high-frequency radio waves used for radio communications will be blocked
Answer: extra currents in the ground will disrupt power grid operations and high-frequency radio waves used for radio communications will be blocked
Explanation:
In the case of a severe geomagnetic storm, extra currents on the ground will disrupt power grid operations and signals from radio navigation systems will be disrupted and be inaccurate.
A geomagnetic storm is caused by a CME (coronal mass ejection) from the sun that smacks against the earth's magnetic field and causes issues such as
Power grid failuresRadio signal disruptionsDamage to critical electronicsEtc.
Extra currents in the ground caused by the geomagnetic storm will disrupt power grid operations. We can also expect a disruption of all radio signals and communications due to changes in the ionosphere during the storm.
Satellites in the Earth's orbit would likely sustain critical damage and may be rendered inoperable, however, since satellites do not use technology to stay in orbit (this is done by the earth's own gravity) they will not fall to the surface, which is why this option is wrong. The final option is also wrong because high-frequency radio waves used for radio communications will be disrupted and unreliable but not blocked.
That is why In the case of a severe geomagnetic storm, power grid operations and signals from radio navigation systems will be disrupted and be inaccurate.
