Answer:
Folds are usually formed by Compression
Explanation:
Compression has to do with applying force to a material or substance to give another shape, in order to get a fold compression is used.
Answer:
because somethings could go out into the ocean and harm sea animals like turtles some get stuck in plastic and some die because of water poeple throw away and if that continued we may make all the sea life die because of that
Answer:
c. is inactivated by binding lactose
Explanation:
Lactose is a sugar mostly present in milk or dairy products. It is degraded in the body by an enzyme called LACTASE. Since lactase is an enzyme (protein), it must be encoded by a structural gene (Lac gene). However, the expression of this structural gene can be inhibited by the absence of lactose.
Ideally, when lactose is present, it binds to a DNA binding protein called Lac repressor protein (inhibitor) causing the inhibitor protein to lose its shape and fall off, allowing transcription of the lac gene to occur. In other words, the presence of lactose deactivates the inhibitory function of lactose repressor protein.
Answer:
repulsion (trans)
Explanation:
Repulsion refers to the phenomenon by which each homologous chromosome contains one dominant and one recessive allele from two different linked genes. A <em>trans</em> arrangement occurs when an individual is heterozygous for two linked genes, where the recessive allele for one particular gene is located on the same chromosome as the dominant allele for the other linked gene, thereby dominant and recessive alleles are said to be “in repulsion”. Conversely, a <em>cis</em> arrangement occurs when both dominant alleles are located on one chromosome and both recessive alleles on the other.
