Hello my name is Tobie and I will be more than glad to help!
your answer should be alpha particle
consisting of two protons and two neutrons emitted by radioactive materials we get what is called a alpha particle
they are usually formed when identical to the nucleus of the helium-4 atom are emitted by radioactive matter !
What can they do to the body?
Since they have radioactive material in them they are very DANGEROUS! If they are inhaled swallowed or somehow get inside our bodies it can cause serious harm!They can harm sensitive living tissue and can go as far as to causing cancer !
What is their electric charge?
+2 e
What is their symbol ?
α, α2+, He2+
Hope this helps!

Answer:
Explanation:
If im correct, the pea plant study was a way to use plants with their different traits to study Dominant and Recessive traits in plants.
He crossed a smoother pea with a more wrinky one and used the offspring as a way to determine dominant and recessive phenotypes.
I may be incorrect but I hope this helps!
Answer:
Well honestly almost every living things contains cells but in this case yes calcium is made up of cells.
Explanation:
Calcium ions are either pumped out of the cell by a specific plasma membrane, Ca2+-ATPase (PMCA), or back into the sarcoplasmic reticulum by SERCA. The PMCA are encoded by at least four genes, PMCA1 and 4 are the most widely expressed and are the two isoforms expressed in vascular smooth muscle cells.
Answer:
Option B, blocking alpha-1 receptors found in smooth muscle in the bladder neck and prostrate, causing them to relax
Explanation:
The subtype alpha (1A) of alpha (1) adrenoceptors are mainly responsible for expressing and contracting bladder neck, urethra and prostate thereby enhancing bladder outlet particularly in elder men (45 Years above) who have enlarged prostates.
If this alpha-1 andrenoceptors found in smooth muscle of bladder neck and prostrate are blocked somehow, then the muscles will relax and this how antiandrogens are used for treat ing benign prostatic hypertrophy
If these α1A subtype receptors are stimulated by norepinephrine, then smooth muscles are caused thereby producing a physical block at the bladder neck
Hence, option B is correct
