Answer:
Bacteria and protists are unicellular organisms. The difference lies in the type of cells they have. Bacteria are placed in the kingdom Monera and have a prokaryotic cell, whereas protists are placed in the kingdom Protista and have a eukaryotic cell.
Answer:
8 chromosomes
Explanation:
Diploid state is when an organism have two set of chromosomes (2n) i.e. combination of two haploid (n) gametes containing one set of chromosome each. Sexually reproducing organisms whose somatic or body cells are diploid (2n) undergo meiosis to produce gametes or sex cells with haploid number (n).
Therefore, in the newly discovered Biologica terificia species of snail, if the haploid state (n) of their gametes is 4, then their diploid (2n) somatic cells must be 4 × 2 = 8.
The question specifies the chromosomal number at the G1 phase of Interphase. At this stage, the cell is preparing to undergo division by increasing in size and duplicating its organnelles but not yet its genetic material which is not until the next phase called S-phase. Hence, the chromosome number of somatic cells remain 8 at the G1 phase.
Answer:
a. As a blood clot begins to form, the process of its formation gets faster and faster.

Answer:
A double blind experiment
Explanation:
A double-blind experiment refers to an experiment in which the information about the treatment of the studied variable is provided to neither the researcher nor the participant. In this type of experiment, both the participant and the experimenter are unaware that which participant has got the experimental treatment.
This test is used by the drug researcher in which the placebo treatment along with experimental treatment is provided. This experiment is performed to ensure that the results are unbiased and the chances of errors and prediction get reduced.
Thus, A double-blind experiment is correct.
There are many factors that affect the rate of chemical reactions and temperature is one of them.
Typically, the higher the temperature of a chemical reaction the faster the reaction occur, that is, the temperature and the rate of chemical reaction are directly related. This is due to the fact that increasing the temperature of the reaction increases the kinetic energy of the reacting particles and thus they are able to move faster and the reaction also occur faster. Thus, from the options given, the correct answer will be D [40 degree], this is because, it is the highest temperature out of all the options given.
