Answer:Are the offspring genetically the same or different from their parents?
Explanation:Changes (mutations) to genes can result in changes to proteins, which can affect the structures and functions of the organism and thereby change traits. Variations of inherited traits between parent and offspring arise from genetic differences that result from the subset of chromosomes (and therefore genes) inherited.
Answer:How can offspring be different from parents?
Explanation:Although an individual gene may code for a specific physical trait, that gene can exist in different forms, or alleles. ... In other cases, each parent provides a different allele of a given gene, and the offspring is referred to as heterozygous ("hetero" meaning "different") for that allele.

What evidence suggests that epigenetic effects may cause these phenotypic differences in monozygotic twins
Answer:
Epigenetic marks (e.g., DNA methylation patterns) in older twins are more pronounced than in younger twins
Explanation:
Epigenetics refers to any heritable phenotypic change that does not involve alterations in the DNA sequence but impacts gene expression. Epigenetic modifications can be classified into three types: DNA methylation, histone modifications (i.e., acetylation, methylation, phosphorylation, etc) and regulatory non-coding RNA (ncRNAs) pathways. Epigenetic modifications in (epi)genome enable to explain how two individuals with identical genetic material (such as monozygotic twins) can have different phenotypes. In older twins, epigenetic differentiation will be higher than in younger ones due to the divergence between epigenomes as a result of age.

Amylose is Select one: a. a long, straight glucose chain. b. branched glucose chains. c. a long, straight fatty acid chain. d. branched amino acid chains.
Answer: A long, straight glucose chain (a major constituent of starch)
Explanation: Starch is mostly amylose (straight chain glucose polymer) but has varying amounts of branched glucose chains (amylopectin).
Fatty acids are hydrocarbons with a carboxylic acid group (-COOH) attached, so they are hydrophobic (don't mix with water) at one end and hydrophilic (water soluble at the COOH end)
Simple carboxylic acids don't have a long enough hydrocarbon chain to have this characteristic, e.g. CH3COOH acetic acid
Typical fatty acids found in nature include stearic acid with an 18-carbon chain
CH3-(CH2)16-COOH

Which structure is représented by the letter A in the diagram above?
Answer:
The stigma, a female structure which collects pollen and passes it to the ovary
Explanation:
The structure represented by the letter A in the diagram is the stigma.
The stigma of a flower represents part of the female reproductive structure. The surface of a mature stigma is sticky and as such, it is able to attract pollen grains from the anther. A pollen that lands on the stigma germinates and its pollen tube grows through the style of the stigma down to the ovule where one of the sperm cells of the pollen fertilizes the egg cell of the ovule to form a diploid zygote and the other sperm cell fuses with the polar nuclei of the ovary to form a triploid cell that eventually becomes the endosperm.
The sepal and the petal are labeled as D and C in the diagram respectively while the stamen is made up of B and H.

When the rule of 70 applies to population, dividing 70 by the percentage of population growth should equal the time (in years) that the population needs to be double (option A)
Explanation:
The rule of 70 is useful to calculate the time in which a variable of any type can be duplicated. The calculation is done by dividing the number 70 by the percentage of growth of the variable.
If the rule of 70 is applied to the population, it is possible to calculate, based on its growth rate, the time that population would need to double.
If, for example, the growth rate of a population is 3 percent:
70 / 3 = 23,33
This indicates that a population, with a growth rate of 3% would need about 23,33 years to double.

Incomplete question. The full question read;
6. Which isn’t a word that shows the outlet isn’t completely sure about a particular statement?
Answer:
certainly
Explanation:
Of course, media outlets would not use the word "certainly" to refer to a particular statement they are not sure of because the word is used connotatively when what is been said is believed to be true.
Hence, other words such as "possibly", "likely" are used when they are not completely sure about a statement.
Synonyms are different words same nearly meaning. 'certainly' is a word that shows the outlet isn't completely sure about a particular statement.
Synonyms:
These are different words same meaning. For example Likely and possibly.
Likely:
It means there are possibilities that work is going to be done.
Certainly:
This shows the full in the statement.
Expected:
There is an expectation that the work will have been done.

Short hair (L) is dominant over long hair (1) in rabbits. Two heterozygous rabbits are mated. Show the punnett square. What phenotypes are expected, and in what
ratios of the bunnies produced? Parents Genotypes:
Answer:
When two heterozygous short haired rabbits are crossed, the short hair being dominant and the long hair recessive, the phenotypes in the offspring will be 75% short hair and 25% long hair, with a short hair:long hair ratio of 3:1.
Explanation:
The crossing of two hybrid individuals for a trait has the probability of producing offspring that exhibit the dominant trait at 75% and the recessive trait at 25%, with the ratio of the dominant trait to the recessive trait being 3:1.
Considering the hair length trait, in rabbits the short hair (L) is the dominant trait and the long hair (L) is recessive, two heterozygous hybrid individuals Ll are crossed:
Genotype of the parents:
♂ Ll ♀ LlLl X Ll
Punnett Square
Alleles L l
L LL Ll
l Ll ll
Where the offspring have a genotype:
Ll 50%
LL 25%
ll 25%
With a ratio Ll:LL:ll of 3:1:1.
Phenotype:
Short hair 75%.
Long hair 25%.
Phenotypic ratio short hair: 3:1 long hair.
In the crossing of two heterozygous short-haired rabbits, taking into account the dominance of the short hair, phenotypes in the offspring will be 75% short hair and 25% long hair, with a short hair:long hair ratio of 3:1

Marissa is conducting an experiment in which she needs to test for acids in water. She is using a substance she believes will turn green when put into different acid solutions. She finds that sometimes the substance turns green but other times it does not. Marissa wants to use this substance in her experiments, but it must consistently turn green in the presence of acid. Which approach should she take to solve her problem?
Answer: she wants the water to turn green and green is neutral on the PH scale. If the water is turning acidic she might want to add a bit of baking soda to balance out the acidity with a bit of alkaline. Minerals can balance acid. If the water is too much of a base she may consider adding something a little acidic to balance it.
