Answer:
the proton and the neutron
Explanation:
An atom is made up of subatomic particles; neutrons, protons and electrons. The protons are positively charged subatomic particles found in the nucleus with a mass equal to 1.6 \times 10^{-27} kg. The electrons are negatively charged particles of an atom found in the orbital shells in constant motion. They have a mass equal to 9.1 \times 10^{-31} kg. The neutrons are particles found in the nucleus that have no charge and have a mass equal to 1.6 \times 10^{-27} kg. therefore protons and neutrons are similar in mass.
Answer:
Provide a closed environment.
Clean the hatch chamber with chemical.
Explanation:
Biosecurity is a measure which is taken in order to protect or prevent the population of existing species from infestation of harmful organisms and chemical substances. The hatchery should provide a closed environment in order to prevent the entry of harmful organism. Cleaning of the chamber where eggs were hatched with chemicals in order reduce the infestation of microorganism.
I know this isnt an exact answer but the easiest way to find this is online you really did not need to ask here but heres the answer any way. <span>Cell wall, chloroplasts, central vacuole.</span>
Answer:
True
Explanation:
Meiosis is the kind of cell division that results in the production of daughter cells with each cell having half number of chromosomes as the parent cell. Meiosis is the cell division employed by reproductive cells to produce gametes/sex cells. Meiosis occurs in two stages i.e. Meiosis I and II. The chromosome number reduces by half in gametes in order to ensure that after fertilization of both male and female gamete, the resulting organism has the correct set of chromosomes. e.g diploid organism produces haploid gametes which fuses to produce a diploid organism again.
Mitosis is another type of cell division that results in identical daughter cells. They are identical in the sense that they possess the same number of chromosomes as the parent cell that divided. For example, a diploid cell undergoes mitosis to produce two diploid daughter cells.
The answer is B. <span>hairy stems (dominant).
</span>If:
H - the dominant allele for hairy stems,
h - the recessive allele for non-hairy stems,
then:
HH - dominant homozygote with hairy stems,
Hh - heterozygote with hairy stems,
hh - recessive homozygote with non-hairy stems.
In autosomal dominant traits, the phenotype is
present if both copies of the dominant allele (H) are present (homozygous
individuals HH) or only one copy of the dominant allele is present
(heterozygous individuals Hh).
In this case all of the batch of tomato plants were <span>heterozygous individuals Hh with hairy stems:
</span>
Parental generation: HH x hh
F1 generation: Hh Hh Hh Hh
