Answer:

<h2>A. algae.</h2>

Explanation:

An algae can reproduce sexually or asexually. Sexually involving sex cells like gametes. Its sexual reproduction is given by meiosis which consists of the separation of genetic information forming another ''body''. During this process an alternation of generations life cycle is developed, because it change their nuclear phases, involving diploid and haploid phases.

"You discover a new species of snail, Biologica terificia, and find that its haploid number is 4 (n = 4). The somatic cells of B
Georgia [21]

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.

1. What does the electric field strength
antiseptic1488 [7]

Answer:

Option A. magnitude

Explanation:

Electric field is the area around the electric current where its effect is observed. If the lines of electric field are close to each other, it means electric field is stronger and if the lines are far away from each other so it indicates that the electric field is weak. There is inverse relationship between electric field and distance from the charge. If the distance is higher, so the electric field is weak and vice versa.

Use the codon chart to convert this sequence into an amino acid: UCU-CGA-GCC-GUU-GGG-UGA
RUDIKE [14]

The answer is Ser-Arg-Ala-Val-Gly-STOP


It is known that three nucleotide bases on mRNA are called codon and that each codon codes for the specific amino acid. According to the genetic code chart, the following mRNA sequence will code for the following amino acid sequence:

mRNA sequence:       <span>UCU CGA GCC GUU GGG UGA</span>

Amino acid sequence: Ser   Arg    Ala   Val    Gly   STOP
