Answer:
The percent chance that the offspring will have a single comb is 
%
Explanation:
Given,
The allele for single comb represented as "a" is recessive to the allele for pea comb represented as "A"
Genotype of male - Aa
Genotype of female - Aa
Gamete of Male - A, a
Gamete of female - A, a
Cross between Aa and Aa will produce
AA, Aa, Aa, aa
Thus, out of four offspring only one has "aa" genotype and hence this individual will express the recessive trait i,e aa
The percent chance that the offspring will have a single comb is
%
This organism is a coyote brush or the Baccharis pililaris. It is a shrub that is a family of daisy. They are mostly found in California, Washington and Oregon. This plant takes a different shape depending on the environment where it is found. It grows in a chaparral biome where there is little biodiversity and a habitat of only few species.
Answer:
c. a high percentage of very long chain saturated fatty acids
Explanation:
Saturated fatty acids do not have double bonds (they are saturated with hydrogens), so their tails are relatively straight. Unsaturated fatty acids, on the other hand, contain one or more double bonds, which often produces an elbow or bend. (You can see an example of an unsaturated bent tail in the phospholipid structure diagram that appears at the beginning of this article.) Saturated and unsaturated phospholipid fatty acid tails behave differently when the temperature drops:
- At colder temperatures, the straight tails of saturated fatty acids can be tightly bound, producing a dense and quite rigid membrane.
- Phospholipids with unsaturated fatty acid tails cannot bind so closely due to the bent structure of their tails. For this reason, an unsaturated phospholipid membrane remains fluid at lower temperatures than a saturated phospholipid membrane.
Most cell membranes contain a mixture of phospholipids, some with two saturated (straight) tails and others with a saturated tail and an unsaturated (folded) tail. <u>Many organisms — fish, for example — can adapt physiologically to cold environments by changing the proportion of unsaturated fatty acids in their membranes, that is, increasing the proportion of saturated long-chain fatty acids.</u>
In addition to phospholipids, animals have an additional component in their membrane that helps them maintain fluidity. Cholesterol, another type of lipid that is embedded between the membrane phospholipids, helps decrease the effects of temperature on fluidity.
I'm pretty sure it's answer D. It's the only answer choice that really makes sense.
Answer:
Longest interval during which no tree-cutting sample occurred: 9 years (1203 AD - 1212 AD)
First year in that interval: 1203 AD
Explanation:
Lets complete the question first.
Q) A study uses tree rings to determine the year in which a tree was cut. The data is shown in the leaf and stem diagram in the ATTACHMENT.
The three digits number in the left column represents centuries and decades AD. The numbers on the right represents the years.
For example, consider the first input in the diagram
119 | 5 6
which means it represents 2 samples.
1195 AD, 1196 AD.
The longest interval with no tree-cutting samples is found from 1203 AD to 1212 AD.
