You may feel cold when you touch certain kinds of matter because some matter gives off cold air. I’m NOT SURE
Answer:
Hello! so this is what I was able to find related to your question.
Explanation:
The oxidation number of this molecule, called a bromate molecule, is -1. It should be correctly written BrO3-. It has this net charge of negative 1 because the bromine has an oxidation number of +5, while oxygen has it's normal oxidation of -2.
Explanation:
Steroid contains a steroidal ring and are devoid of fatty acid chain. The steroidal nucleus is a fused ring consisting of three six membered rings, and a five membered ring.
Examples of steroidal molecules include, cholesterol, steroidal hormones such as estrogen(estradiol) progestrone, testoterone and corticosteroidal hormones such as cortisol, aldosterone and cortisone.
Answer:
Option B is correct. A nuclear alpha decay
Explanation:
Step 1
This equation is a nuclear reaction. So it can be an alpha decay or a beta decay
An α-particle is a helium nucleus. It contains 2 protons and 2 neutrons, for a mass number of 4.
During α-decay, an atomic nucleus emits an alpha particle. It transforms (or decays) into an atom with an atomic number 2 less and a mass number 4 less.
Thus, radium-226 decays through α-particle emission to form radon-222 according to the equation that is showed.
A Beta decay occurs when, in a nucleus with too many protons or too many neutrons, one of the protons or neutrons is transformed into the other.
Option B is correct. A nuclear alpha decay
Answer:
100% pea plants will be with green pod and with round seeds.
Explanation:
As per the question given, a homozygous pea plant having green pod (gg) and round seeds (WW) is crossed with a pea plant having homozygous green pod (gg) and heterozygous round seeds(Ww). A pea plant homozygous for green pod and round seeds (ggWW) will produce one type of gametes having alleles (gW), whereas, a pea plant homozygous for green pod and heterozygous for round seeds(ggWw) will produces two type of gametes having alleles gW and gw. On crossing, phenotypically, they will produce all pea plants with green pod and round seeds. But genotypically, 50% of green pod pea plants with homozygous round seeds and 50% of green pod pea plants with heterozygous round seeds.
