Okay what u want me to help you with
Answer:
a
Explanation:
y=-2/3x+7 you multiply everything by 3 to cancel the fraction
3y=-2x+21 add 2x to both sides cuz u want the x and y on the left side for standard form
2x+3y=21
Answer and Explanation:
Many elements can be responsible for this, among them, we can mention the presence and absence of predators in the different places on the rocky coast. This is because predators can influence not only the number of organisms found, but also the types of organisms.
Another element that may be the cause of this variability is the availability of resources necessary for the life of these organisms, in addition, the impact of the waves on the rocks, can cause the variability of the organisms, since some may not be able to resist the impact of the waves.
Answer:
Plants are valuable since they provide our food, materials for shelter, and purify the air (photosynthesis).
Animals such like livestock, supply us with food, fiber and leather.
The Endangered species act can help a local economy because it helps to supply clean air and pure water. It also protects our natural supplies.
Explanation:
A frameshift mutation is an insertion or deletion in a sequence of DNA which disrupts the way the code is read. It occurs when the codons undergo a disruption through the deletion or insertion of one or multiple nucleotides (given that the number removed or added are not multiples of 3) - this alters the open reading frame; the amino acids produced through translation simply occur in a different sequence.
Further Explanation:
During the process of cell division, spontaneous changes within the genome can arise. These mutations are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes. There are two types:
- somatic: these only occur within certain cells, and arise from environmental factors such as UV light
- hereditary: occur within germ cells of the parent and later the fertilized egg which forms a zygote; these are present within all cells of the new organism.
