b. more wheat and less canola grown as crops
c. greater threat to forests from insect pests
d. greater biodiversity of wetland species
e. better agricultural conditions in northern Alberta
f. improved air quality in urban areas
thanks!
Answer:
a. more stable weather conditions --- NE
b. more wheat and less canola grown as crops ---E
c. greater threat to forests from insect pests ----E
d. greater biodiversity of wetland species ----E
e. better agricultural conditions in northern Alberta ----E
f. improved air quality in urban areas-----NE
Explanation:
The climate of Alberto change with the increase in temperature which disturb the weather condition of the region. This increase in temperature decreases the production of wheat crop so more wheat crop is cultivated for fulfilling the needs. This increase in temperature make the environment more suitable for different organisms. The climate is cold during winter so increase in temperature causes condition suitable for agriculture in northern Alberta. Improved air quality in urban areas is not possible due to more production of carbondioxide gas which leads to increase in temperature.
DNA: TTA CGC AAC TGG CTA ATT
mRNA: AAU GCG UGA CCG AUU AAC
Identify the type of mutation that occurred in the sequence above and evaluate the significance of these changes. (Will it have any problems in protein synthesis?)
Hint: 1st determine if it was copied to mRNA correctly. When you find the error, that is the mutation. 2nd use the chart if a different amino acid is created, this will determine if it will affect protein synthesis.
Answer:
See the answer below.
Explanation:
The correct mRNA sequence from the DNA according to the base pairing rule should be:
AAU GCG UUG ACC GAU UAA
Instead of:
AAU GCG UGA CCG AUU AAC
This thus means that some of the nucleotide bases have been wrongly substituted.
The most important change is the codon 'UUG' becoming 'UGA', while the former codes for the amino acid leucine, the latter represents a stop codon. A stop codon will result in a non-functional or defective protein.
Hence, the type of mutation is nonsense mutation which results in a sudden cessation of protein synthesis as a result of a codon being prematurely changed to a stop codon.
The significance of this kind of mutation is that a defective on non-functional protein will result which will have a serious phenotypic implication in organisms.
Where are metamorphic rocks likely to form?
Answer: deep in planets crust
Explanation:
Although metamorphic rocks typically form deep in the planet’s crust, they are often exposed on the surface of the Earth. This happens due to geologic uplift and the erosion of the rock and soil above them. At the surface, metamorphic rocks will be exposed to weathering processes and may break down into sediment.
Explain how is it possible to have twins that are not identical
Fraternal (dizygotic) twins come from 2 different fertilized eggs that both grow in the mother's womb. They have different DNA (2 eggs from the mother, 2 sperm from the father) and are not identical, although they often look alike.
Identical (monozygotic) twins come from one fertilized egg that has split in two. These twins share the same DNA and are completely identical.
Identical twins develop from the same egg and sperm,the embryos split and form identical twins ,they are the same sex. But some are fraternal twins, they develop with two diferent sets of sperm and eggs by the same parents. They can be from diferent, this is like having diferent babies at the same time.

Water makes up a large percentage of the body’s cells. For a cell to remain in homeostasis, there must be a mechanism to control water changes in the cells. The movement of water from an area of high water concentration to an area of low water concentration is . osmosis,diffusion,active transport or stable transport
Answer:
Explanation:
active transport
Does evolution occur at the individual or population level?
Answer:
populations
Explanation:
this is because individual species are not changing. Populations are evolving. Since people in a group differ, those of the population are more able to live and replicate owing to a specific range of environmental conditions.
hope this helped!
Explanation:
the process of evolution occurs only in population and not in individuals . all single individual can not evolve alone evolution is the process of changing the gene frequencies with in a gene pool .

what is the level of organization in an organism ?
Cellular organization is one of the characteristics of a living organism which states that each living organism is made up of a single cell or more than one cell.
It is made up of various components such as chemicals like micro molecule that form the macro molecule, at chemical level the structural composition are organized together to make cells
At Cellular level of organization form the tissue and it is complex to cell but simpler to organ which makeup of various together.
The cluster of interacting organs is necessary as the organ which are the structural level that individuals do the specific function.
Organs are gather together form organ system and it is a complex system made up of organs that are similar in their function.
