Answer:
1- The CRISPR-Cas system
2- Genetically modified organisms raise concerns associated with allergic reactions, horizontal gene transfer and outcrossing
Explanation:
The CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats)-Cas (CRISPR-associated) technology is widely used in medicine and research. The CRISPR-Cas is a versatile RNA-programable genome editing system capable of introducing genetic modifications at target DNA sequences. This technology is based on the natural bacterial immune system that cleaves bacteriophages and plasmid DNA sequences. Moreover, Genetically Modified Organisms (GMO) have historically raised three major concerns on human health: 1-the allergenicity of GMO foods, 2-the ability that GMOs might have to insert genes through horizontal transfer and 3-outcrossing between GMOs and (genetically) unmodified crops, which are further consumed as non-GM foods.

What is NOT apart of a seed?
Answer:
A) Stigma
Explanation:
This option makes the most sense of all of them. The food storage option is incorrect because food storage is a part of a seed. The stigma is part of producing the seed, not part of the actual seed. The testa is the seed coat (part of a seed). The plumule is also part of a seed (stem or seedling).

How is energy stored when ADP is converted to ATP?
Answer:
Energy is stored in the bonds between the phosphate groups (PO4-) of the ATP molecule. When ATP is broken down into ADP (adenosine diphosphate) and inorganic phosphate, energy is released. When ADP and inorganic phosphate are joined to form ATP, energy is stored.

The order of the genes on a plant chromosome is A, B, C, where A and B are located 10 cM apart and B and C are located 3 cM apart. What is the probability that the trihybrid ABC/abc will produce any kind of recombinant gamete
Answer:
Double Crossing-over prob = 0.3% Simple Crossing-Over prob A-B = 9.7%Simple Crossing-Over prob B-C = 2.7%Total Crossing-Over prob = 12.7%Explanation:
Available data:
order of the genes on a plant chromosome is A, B, CA and B are located 10 cM apartB and C are located 3 cM apartThe genetic distance = recombination frequency x 100 expressed in map units (MU). One centiMorgan (cM) equals one map unit (MU).
We can use the provided map with the distances between genes to predict the occurrence of any kind of recombinant gamete.
We know that there is a probability of a simple crossing over to occur between genes A and B, or between genes B and C. And we also know that there is a probability of double crossing-over occurrence.
We can get the probability of the double-crossing over by multiplying the recombination frequencies between A-B and B-C. So,
DCO prob = recombination frequency A-B x recombination frequency B-C
= 0.1 x 0.03 = 0.003 = 0.3%
DCO prob = 0.3%
According to this, we would expect to find
0.15% AbC0.15% aBcNow we need to know what are the probabilities of getting a simple crossing-over, SCO. We already have the genetic distances between genes. 10 cM equals 0.1 of recombination frequency, and 3cM equals 0.03 of recombination frequency. However, we can not estimate the probabilities of simple crossing over using only this information, because this data is including the probabilities of the double crossing-over occurrence. So we need to substrate this percentage.
SCO prob A-B = 0.1 - 0.003 = 0.097 = 9.7%
SCO prob A-B = 9.7%
we would expect to find
4.85% Abc4.85% aBCSCO prob B-C = 0.03 - 0.003 = 0.027 = 2.7%
SCO prob B-C = 2.7%
we would expect to find
1.35% ABc1.35% abCThe total Crossing-over probability, TCO, is then the sum of all the crossing over probabilities,
TCO= SCO A-B + SCO B-C + DCO
TCO prob = 9.7% + 2.7% + 0.3%
TCO = 12.7%

What if cellular respiration did not occur
Answer:
cellular respiration is a process that needs oxygen, so when oxygen is not present, they do not happen, but there is glycolysis, which doesn't need oxygen. the process of glycolysis produces 2 ATP and that is what is needed, so to continue glycolysis, the cells go through fermentation.
Explanation:
THE ANSWER IS FERMENTATION!!!!
Answer:
If cellular respiration does not occur, then the level of oxygen present in the cell will get decreased as a result cell can die due to lack of oxygen. This is because cellular respiration provides the energy necessary for cellular activities.

What is Fertilization in plants?Fertilization is defined as the process of sexual reproduction, which occurs after pollination and germination which can be defined as the fusion of male gametes called pollen with female gametes called as ovum to form diploid zygote. It is a physio-chemical process that occurs after pollination of the carpel.
Steps of Fertilization occur in Plants
1. Pollination
2. Germination
3. Fertilization
Fertilization occurs through the pollen tube opening into the ovule through the micropyle and bursting into the embryo sac where the male nucleus fuses with an egg nucleus inside the ovule to form a diploid zygote, which then swells and develops into a fruit. These plants are similar in appearance when grown from seed but with the tuber method they will appear identical but not with the mother.
Thus, they will look the same because the plants grown from seeds are genetically identical to one another but not to the mother plant. So, the correct option is (A).
