I think the answer is Passive
After looking at the above diagram given, Enzymes are the molecules that were used to cut, copy, and to connect the DNA segments. The correct answer is 2. Make sure to check the number choices, they are out of order on this particular question.
The use of chemicals on crops poses known health risks to humans. this statement most support a decision to buy organic produce.
- The agriculture industry has become more industrialized, which has increased the chemical load on the environment.
- Agrochemicals known as pesticides are applied to agricultural fields, public health initiatives, and urban green spaces to protect people and plants from numerous diseases.
- Their side effects, however, can be a significant environmental health risk factor due to their proven capacity to have a wide range of detrimental health and environmental impacts.
- Produce that is organic uses fewer pesticides.
- Because organic food lacks preservatives that extend its shelf life, it is frequently fresher.
- Organic farming typically benefits the environment.
- Animals kept organically are not fed animal byproducts, growth hormones, or antibiotics.

An extinction event is a well-known
and quick decrease in the biodiversity on Earth. Such an occurrence
is recognized by a sharp change in the diversity and abundance of multicellular organisms. It happens when the
rate of extinction surges with respect to the rate of speciation.
In other words, this happens when species cannot adapt generally to the change
in the environment. So the correct answer would be letter a.
Answer:
- The blood group of the father must be B.
- The genotype of blood group would be
. - The Rh factor of the father can either be positive or negative.
- Thus, the genotype of Rh factor of father would be either Rr or rr.
Rh factor:
The phenotype of the mother Rh factor is positive. Thus, she can have Rr or RR as her genotype as positive is a dominant trait.
If the genotype of the mother is RR then all the offspring would be positive for Rh factor. However, one of the offspring is Rh negative, that means the mother must be heterozygous that is, Rr.
The genotype of the father can either be Rr or rr in order to produce offspring with positive as well as negative Rh.
Blood group:
The blood group of the mother is A. Thus, the genotype can either be 
or 
.
However, the blood groups of the children are O+ and B+.
Thus, the genotype of the mother must be heterozygous that is .
The blood group of the father must be B with genotype in order to produce offspring with blood group O and B.
