Can genetic engineering cause harm to humans?
Answer:
There are many risks involved in genetic engineering. The release of genetically altered organisms in the environment can increase human suffering, decrease animal welfare, and lead to ecological disasters. The containment of biotechnological material in laboratories and industrial plants contributes to the risk of accidental release, especially if the handling and storage are inadequate.

Why does a floating leaf indicate that photosynthesis is occurring?
Answer and Explanation:
A floating leaf indicates that photosynthesis is occurring because it means the leaf is producing oxygen, a biproduct of photosynthesis. It is possible that photosynthesis is occurring in a leaf that is not floating because it's possible that the leaf is denser than the solution and can't float.

What items are used to identify the genetic makeup of an unknown organism?
Answer:
Polymerase chain reaction machine
Primers
Petri dishes
Test tubes
Pipettes
DNA Polymerase
Free nucleotides
The organism to be identified
Explanation:
To identify the genetic makeup of an unknown organism, the nucleotide sequences fond in the Deoxyribonucleotide (DNA) of a known organism is matched to the DNA of some known organisms. If there is a certain degree of sameness in most of the matched parts, then the unknown organism can be said to be related to the known organism. This is a comparative study.
To carry out this identification, items used include; primers, the PCR machine, test tubes, DNA polymerase, free nucleotides, etc.

On the planet Kermit, in the Muppet population, there are two autosomal loci of interest. The first locus has alleles A and a, and the second locus has alleles B and b. A and B are the dominant alleles at the respective loci. The loci act in an epistatic manner, identical to the way two genes interact to produce coat color in labradors. The phenotype here is muppet hair color. We have the following results:
Muppet hair color as a function of two-locus genotypes
Two-locus genotype Muppet hair color

Why is genetic variation among individuals beneficial?(1 point)
A) More genetic variation means higher rate of survival versus species that have less genetic variation.
B) Genetic variation staves off extinction because it creates a fit population.
C) Some individuals will have inherited traits that give them a competitive advantage that make them more likely to survive and reproduce.
D) Genetic variation leads to more new traits in the population which means evolution can occur faster.
Answer:
Some individuals will have inherited traits that give them a competitive advantage that make them more likely to survive and reproduce.
Explanation:
it was the correct answer from the test
Genetic variations may lead to the diversity in the phenotypes of surviving individuals. It reduces the chances of extinction.
What do you mean by Genetic variations?Genetic variations may be defined as the presence of differences in sequences of genes between individual organisms of a species.
Genetic variation among individuals is beneficial because some individuals will have inherited traits that give them a competitive advantage that make them more likely to survive and reproduce.
Therefore, it is discussed above that genetic variation among individuals is beneficial.

Explanation:
When exercising routinely, timing the food that you eat around your exercise activities is important. Carbohydrate intake is particularly influential, with different ideal timings for simple carbohydrates and complex carbohydrates. The best types of carbohydrates to eat during and/or immediately after exercise are simple carbohydrates, whereas complex carbohydrates are ideally consumed a couple of hours before exercise. Complex carbohydrates take longer to digest and enter the bloodstream and can help build glycogen stores.
Sort the following food items into their respective bins based on whether they are simple, complex, or noncarbohydrate-rich foods.

-analog signals
-interference
-continuity
-zeros and ones
Digital signals transform sounds into zeros and ones.
Zeros and ones or binary code?Digital sound is all that sound placed on media encoded in binary code. This encoding transforms the microphone signal into a digital code that follows various parameters such as Nyquist's theorem, sample rate, bit depth, bit rate, dithering, etc.
Whit this information, we can conclude that digital signals transform sounds into zeros and ones(binary code).

DNA replication is said to be semiconservative. Which of the following statements correctly explains what this means?
Answer: DNA is a double stranded molecule. When DNA is copied the two strand of DNA (old strands) separate and new nucleotides match up with the two separated strands.
This process creates two identical double stranded DNA molecules are formed. Each DNA molecule contains one strand of the original DNA molecule and one newly synthesized (made) strand.

The semi-conservative nature of DNA replication illustrates that each strand in the DNA double helix function as a template for the synthesis of a new or complementary strand.
What is DNA replication?DNA replication may be defined as a type of biological process that deals with the synthesis of two identical replicas of DNA from one original DNA molecule during cell division.
The semi-conservative model of DNA was proposed by Watson and Crick. This model implies that each double helix of DNA is composed of one new and one old strand.
In semi-conservative replication, the parental double helix is half conserved and each parental single strand remains intact.
Therefore, DNA replication is said to be semi-conservative due to the process of each new double strand consisting of one parental strand and one new daughter strand.
