The parts from least complex to most complex is muscle cell, muscle tissue, stomach. So, the correct option is (B).
What is Digestive System?The human digestive system consists of the gastrointestinal tract with the accessory organs of digestion which involve breaking down food into smaller and smaller components until they can be absorbed and assimilated into the body.
The GI tract consists of series of hollow organs which is joined in a long, twisting tube from the mouth to the anus. The processes of digestion consists of six processes:-
1. Ingestion
2. Propulsion
3. Mechanical or physical digestion
4. Chemical digestion
5. Absorption
6. Defecation.
The complexity of the digestive system involves muscle cell, muscle tissue, stomach and organ system from least complex to most complex.
Thus, the parts from least complex to most complex is muscle cell, muscle tissue, stomach. So, the correct option is (B).

In shorthorn cattle, when a red bull (RR) is crossed with a white cow (WW), all the offspring are roan—a spotted, red and white color. What offspring are expected from mating a roan bull and a roan cow?
Answer:
25% red
50% roan
25% white
Explanation:
When RR (red) is crossed with WW (white), it results in roan color.
RR (red) x WW (white)
RW (roan)
Two roan individuals are then mated.
RW x RW
RR RW RW WW
Offspring
1/4 RR - Red
1/2 RW - Roan
1/4 WW - White
Hence, the offspring are expected to be 25% red, 50% roan, and 25% white.
A sequence of a DNA template strand is shown below.
3’ T C C A A T G G C T T A T T T G C A 5’
Which of these is the correct amino acid chain produced from the DNA template strand?
Arginine – Leucine - Proline – Asparagine – Lysine – Arginine
Serine - Leucine – Proline – Asparagine – Lysine – Arginine
Tryptophan – Phenylalanine – Leucine – Glycine – Asparagine – Phenylalanine
Tryptophan – Phenylalanine – Leucine – Glycine – Asparagine - Serine
The correct amino acid chain produced from the DNA template strand will be Arginine – Leucine - Proline – Asparagine – Lysine – Arginine. The correct option is A.
What is amino acid?Amino acids are molecules that form proteins when they combine. The building blocks of life are amino acids and proteins.
Amino acids are left over after proteins are digested or broken down. To help the body, the human body uses amino acids to make proteins: Food should be broken down.
A codon is a three-nucleotide (DNA or RNA) sequence that forms a unit of genomic information encoding a specific amino acid or signaling the end of protein synthesis (stop signals).
There are 64 different codons, 61 of which specify amino acids and three of which serve as stop signals.
The amino acid sequence for the given template will be:
3' AGGUUACCGAAUAAACGU 5'
So, as per three letter code, the amino acid chain will be:
Arginine – Leucine - Proline – Asparagine – Lysine – Arginine
Thus, the correct option is A.

Osmosis does not require an additional input of energy from the cell.
Osmosis is considered to be a type of
active transport
endocytosis
passive transport
exocytosis
Answer:
Osmosis is considered to be a type of
active transport.
Explanation:
Answer:
passive transport
Explanation:
Osmosis is the process in which water molecules move from a region of higher water potential to a region of lower potential down a water potential gradient across a partially permeable membrane, so little energy is required to carry out this process, thus it is a form or passive transport.

What are the definitions for gene pool and allele frequency?
A. the alleles for a species, the number of times a gene appears
B.the number of alleles: genes that appear in a population
C.all the alleles that appear in a population: the number of times the alleles appear
D.all the genes that are present in a population; the number of times an allele occurs in a gene pool
Answer:
Allele frequency- the percentage with which a specific allele is found in a population. Gene Pool- the sum total of all alleles present in all populations of a particular species. ... evolution involved a change in allele frequency in a population's gene pool over a number of generations.
Explanation:
I hope this helps :)
A gene pool is defined as the number of alleles. and the allele frequency is defined as the genes that appear in a population. Therefore, option B is correct.
What is gene pool ?A gene pool is the collection of all the genes (including alleles) found in a population or species that is capable of reproduction. A big gene pool has a wide range of genetic diversity and is more resilient to environmental stresses.
A gene pool is the collection of all the genes, including all the various alleles, in any population that mates with other individuals from the same or different species. The percentage of an allele within a population is known as the allele frequency.
A population's gene pool will include a high number of genes with a wide range of frequencies. Gene frequencies are proportions of various alleles within a population, and in any given generation, these frequencies will rely on those of the previous generation.

Describe the steps of protein synthesis in a eukaryote.
The first step in protein synthesis is transcription. The transcription consists of the synthesis of messenger RNA by an enzyme(RNA-polymerase). This process takes place inside the nucleus.
The second step is translation the mRNA exits the nucleus and binds to a ribosome. Ribosomes are the sites of protein synthesis. For every three nitrogenous bases of the mRNA an amino-acid is synthesized. Amino acids are brought to the protein synthesis site by transfer RNA. From this process we are left with a polypeptide.
Transcription is the initial stage of the production of proteins. The process of transcription involves an enzyme producing messenger RNA (RNA-polymerase). The nucleus is where this process occurs.

What is a benefit to utilizing fusion reactions instead of fission reactions?
A)Fusion reactions do not require any kind of radiation shielding to prevent exposure.
B)Fusion reactions do not produce harmful radiation and transuranium nuclides.
C)Fusion reactions can proceed in any temperature range.
D)Fusion reactions are easier to control and regulate.
Answer:
B)Fusion reactions do not produce harmful radiation and transuranium nuclides.
Explanation:
___________
The benefit of utilizing fusion reactions instead of fission reactions is that the fusion reaction does not produce harmful radiation and transuranium nuclides. Thus, the correct option for this question is B.
What is meant by Fusion?Fusion may be defined as a type of process that significantly involves the combination of two or more atoms or molecules in order to form one larger molecule. This type of reaction normally occurred in nature as compared to fission.
The process of fission involves the disintegration of numerous smaller molecules or atoms from a larger one. This creates a lot of long-lived radioactive substances in nature that are harmful to live organisms. These types of reactions are not favored by nature.
Therefore, fusion reactions do not produce harmful radiation and transuranium nuclides are the benefit of utilizing fusion reactions instead of fission reactions. Thus, the correct option for this question is B.
