Answer:
Natural pollinators, like bees, pollinate flowers randomly, essentially mixing up their genomes and increasing genetic diversity. This leads to different types of future plants. However, artificial pollination is so labor intensive, it's hard to replicate the same variety in pollination.Aug 8, 2017
Explanation:
Artificial pollination is the type of pollination carried out by humans. It is a mechanical technique used to pollinate plants when natural pollination is insufficient or undesirable. It does not require the help of insects or weather.
Natural pollination consists of the transfer of pollen between the male and female organs of the flowers, without human intervention. In other words, pollen is transferred from the stamens to the stigma of the flowers, where it fertilises the ovules, making seed and fruit production possible.
When the genetic material found within an offspring is diverse, what type of reproduction is responsible?
a
Sexual reproduction, because the genetic material comes from both parents
b
Sexual reproduction, because the genetic material comes from one parent
c
Asexual reproduction, because the genetic material comes from both parents
d
Asexual reproduction, because the genetic material comes from one parent
Answer:

If the DNA sequence is --- AAA TAT CCG TAG CAA ATG, write the mRNA sequence, tRNA anticodon sequence, and the six amino acids for this.
adenine(A) binds with uracil(U)
Thymine(T) binds with Adenine(A)
guanine(G) binds with cytosine(C)
The complementary mRNA, which contains the codons is
UUU AUA GGC AUC GUU UAC
The complementary tRNa , which contains the anticodons is
AAA UAU CCG UAG CAA AUG
The six aminoacids are
phenylalanine-isoleucine-glycine-isoleucine-valine-tyrosine
The bases tend to exist as a pair in the DNA’s double helix structure. The bases are bonded by hydrogen bonds.
Their bonds are mentioned as follows:
Adenosine (A) is paired with thymine (T) Cytosine (C) is paired with guanine (G)However, the base thymine (T) is present only in the nucleotide of DNA and the base uracil (U) is present only in the nucleotide of RNA.
Based on the understanding of the nucleotide and central dogma concepts, the following sequences are determined:
DNA Sequence: AAA TAT CCG TAG CAA ATGmRNA Sequence: UUU AUA GGC AUC GUU UACtRNA anticodon: AAA UAU CCG UAG CAA AUGSix amino acids: PHE ILE GLY ILE VAL TYRSix amino acids are namely Phenylalanine, Isoleucine, Glycine, Isoleucine, Valine, and Tyrosine.

How humans changed the balance of the park ecosystem
Answer:
Humans change ecosystems in many ways, such as habitat destruction, pollution, introduction of invasive species, and overexploitation of species.
The most common way that humans damage ecosystems is by destroying habitat. For example, we remove trees, change the flow of water, and change grasslands into farms. These practices can lead to local extinctions of species and cause other species to migrate to new areas.
I dont know if this is helpful but i hope it helps

Instinct or learned behavior?
A lizard becoming ill after eating a poisonous insect?
The response of a lizard becoming ill after eating a poisonous insect is most likely an instinctual behaviour rather than a learned behavior.
What is instinctual behaviour?Instinctual behavior, also known as innate behavior, is a type of behavior that is genetically programmed in an organism and does not require prior learning or experience. These behaviors are often complex and are typically exhibited in response to specific environmental stimuli or triggers. Instincts are common in animals and are often associated with survival and reproduction.
Examples of instinctual behavior in animals include migration, hibernation, nest building, territoriality, and courtship displays. In many cases, instinctual behavior is triggered by external environmental cues such as changes in light, temperature, or food availability.
Humans also exhibit instinctual behavior, although to a lesser extent than many other animals. For example, newborn infants exhibit innate reflexes such as rooting, sucking, and grasping. Some researchers also believe that certain aspects of human behavior, such as language acquisition and social bonding, may have an innate or instinctual component.

All of the following are characteristics of proteins EXCEPT:
A They contain genetic information
B They can catalyze chemical reactions.
c They can transport materials.
D They can repair tissues.
Answer: A.
Explanation: Proteins are made by decoding genetic information carried by DNA, but contain no genetic information themselves. Although the sequence of amino-acids in a protein matches the code in DNA, there is no process for using protein as a template for DNA.
Proteins may be structural, like collagen in tendons or keratin in hair and fingernails, or enzymes active in metabolism, or in transport, such as haemoglobin that transports oxygen, or in transporting ions into and out of cells against a concentration gradient.

If a cell normally has 32 chromosomes, what would be the results of going through mitosis?
Answer:
For mitosis, the DNA content of the daughter cells and the mother cell will always be identical. Since the number of cells have doubled, so has the DNA. The 16 chromosomes in the mother cell will be duplicated, then the duplicates split and evenly divided into the daughter cells. The 16 chromosomes in each daughter cell will be non-duplicated at first.

Shull's hybrid corn seeds created a new type of science in the United States—biotechnology. After the success of his seeds, other individuals entered the field and created their own hybrids. This caused the industry to grow and gave farmers a bigger selection of seeds from which to choose. Today, farmers can purchase everything they need for a successful corn crop from their seed distributors. The hybrid seed industry in the United States makes billions of dollars each year.
B.
From 1866 to 2011, farmers produced many bushels of corn each year. They could have produced more corn if weather conditions had been favorable. The drought during the Dust Bowl was hard on farmers growing corn. Hybrid corn seeds had no effect on corn production. The impact on society and the economy were small compared with the impact of the Dust Bowl droughts.
C.
Shull developed hybrid corn seed about 100 years ago. Some farmers bought the seed when it was first produced, but others did not. Farmers would have grown corn either way. Hybrid corn seed did not have an effect on corn production overall. It helped the economy by making more money for Shull and other scientists that produced hybrid corn seeds.
D.
Shull's creation of hybrid corn seed allowed farmers to produce more corn consistently throughout the years. Overall, the number of bushels harvested each year trends higher, as shown in the graph, between 1918 and 2011. Increased corn production meant more income for the farmers, which allowed them to take better care of their families and farms. Hybrid seed performed, even during the Dust Bowl, when non-hybrid farmers struggled to produce corn.
