Answer: The body systems that are involved are:
--> Nervous System and
--> muscular system.
Explanation:
The body is made up of different organ systems which usually works together to bring about proper functioning of the living organism. Examples of the body systems includes:
--> The nervous system: This system enables the animal to detect and respond to stimuli rapidly.
--> The muscular system: This system enables the organism to move from one location to another.
Both the nervous system and the muscular system work together to bring about coordination of activities. When you step on a tack and jeck away, sensory receptors detects stimuli from the external environment and pass the information received as an electrical impulses to the brain through the nerve fibres. The information is processed in the central processing region which is the brain.
The effectors such as the muscles goes into action upon receiving nerve impulses from the brain. Such actions includes muscular contractions which helps you to pick up the tack and put it on your desk.
Explanation:
<u>C. A red allele is present on both homologous chromosomes</u>
<u></u>
Homologous chromosomes are pairs of chromosome of similar lengths, banding patterns, and centromere positions, with genes at the same loci. For dominance, gene copies are present on both of the chromosomes; the dominat variant overrides the effect of the other recessive allele.
Further Explanation:
DNA molecules contain chromosomes that may have different forms called alleles. DNA, which is the genotype, is transcribed into mRNA and later translated into amino acids which are connected together by rRNA to form proteins which constitute the phenotype of an organism. DNA sequence mutations form new alleles, impacting the associated mRNA, and thus the encoded protein.
Homozygous individuals have a chromosome containing two variants of the same allele. Dominant homozygous individuals bear two copies of the dominant allele, whereas recessive homozygous individuals hold two copies of the recessive allele.

Answer:
A. double-blind
Explanation:
Based on the scenario being described within the question it can be said that the type of trial that she has joined is known as a double-blind study. This is a type of study in which individuals are chosen randomly for each clinical intervention and the results are not given to the researchers until after the trial. This also includes any and all information that may influence the researchers behavior or thoughts on the study.
Answer:
In ecology and Earth science, a biogeochemical cycle or substance turnover or cycling of substances is a pathway by which a chemical substance moves through biotic and abiotic compartments of Earth.
Explanation:
<em>Unknown source.</em>
The correct answer is C. Cladistics is a branch of phylogeny. Cladistics is concerned with all branching. It is a way of grouping branches together while phylogeny is a way of tracking relationships in evolution. Phylogeny shows the history of an organism's evolution.
