In order to improve the graph and make it more detailed in order to get a better perception why the honey bee populations are decreasing, there's few things that can be added.
- Number of bee keepers over the period
The number of the honey bee colonies is directly connected as to how many bee keepers there are. If there's a trend of a decline in the bee keepers, than there will be a trend in the decline of the honey bees.
- Area of trees suitable for the honey bees
The trees are crucial for the honey bees to be able to produce honey, thus it is very important that they have a certain area of trees on which they can feed upon. If there's a decline in the number of trees for the bees, than the bees will be dying from starvation.
- Pollution
The honey bees are animals that are very sensitive to changes in the environment, especially when it comes to pollution. If the levels of pollution are increasing in areas where there's honey bees, it will certainly affect their numbers in a negative manner.
Answer:
plant: This Elodea leaf cell exemplifies a typical plant cell. It has a nucleus, and a stiff cell wall which gives the cell its box-like shape. The numerous green chloroplasts allow the cell to make its own food (by photosynthesis).
The central vacuole takes up most of the volume of the cell. It is transparent, but you can see where it's pressing the chloroplasts up against the cell wall, especially at the ends of the cell.
Like animal cells, the cytoplasm of this plant cell is bordered by a cell membrane. The membrane is so thin and transparent that you can't see it, but it is pressed against the inside of the cell wall.
animal :This human cheek cell is a good example of a typical animal cell. It has a prominent nucleus and a flexible cell membrane which gives the cell its irregular, soft-looking shape.
Like most eukaryotic cells, this cell is very large compared to prokaryotic cells. For scale, notice the pair of dark blue bacteria cells sticking to the right edge of the cheek cell. The bacteria are only a fraction of the size of the nucleus, but their tiny size is typical for bacteria.
Answer:
Valine-Leucine-Proline-Lysine-Histidine
Explanation:
The central dogma of biology is the process by which DNA is used to synthesize RNA and subsequently amino acid sequence (PROTEIN). The processes of transcription and translation is used in gene expression. Transcription is the process whereby the information encoded in a DNA molecule is used to synthesize a mRNA molecule. Transcription is catalyzed by RNA polymerase enzyme, which uses complementary base pairing rule i.e Adenine(A)-Thymine(T), Guanine(G)-Cytosine(C) pairing.
N.B: Thymine is replaced by Uracil in the mRNA
For the above DNA sequence: CAC GAC GGA TTC GTA, the mRNA sequence will be: GUG CUG CCU AAG CAU
Translation is the second process of gene expression which involves the synthesis of an amino acid sequence from an mRNA molecule. The mRNA is read in a group of three nucleotides called CODON. Each codon specifies an amino acid (see attached image for genetic code)
Based on the attached genetic code, an mRNA sequence: GUG CUG CCU AAG CAU will encode an amino acid sequence: Valine(Val) - Leucine (Leu) -Proline (Pro) -Lysine (Lys) - Histidine (His).
GUG specifies Valine amino acid
CUG specifies Leucine amino acid
CCU specifies Proline amino acid
AAG specifies Lysine amino acid
CAU specifies Histidine amino acid
Answer:
Bart was 16 years old when he moved to New Jersey. He was not happy there were very few kids his age in his new neighborhood. During the winter, he noticed that his elderly neighbor, Mr. Jones, was attempting to remove snow from his sidewalk. Bart ran over to Mr. Jones and offered to help him. When summer came, Bart wanted to go swimming in Mr. Jones' pool, and the elderly neighbor smiled and allowed him, with pleasure.
Explanation:
This is a good example of a Life Skills question, where you are being questioned on what is the correct way to deal with people in certain situations. If Bart had helped the elderly neighbor, he would have a positive interaction with him, meaning that he would then not be afraid to approach him in summer.
