The three pillars of Darwin's theory of evolution are genetic variety, fitness, and adaptation. Overproduction and competition are other crucial components of this process.
What Darwin's theory of evolution by natural selection?Charles Darwin's theory of evolution is known as natural selection. Due to the limited supply of resources in nature, animals have inherited traits that aid in both survival and reproduction.
Typically, produce more offspring than their contemporaries, leading to an increase in the frequency of such traits across successive generations.
Natural populations exhibit variation, and every population has more offspring than the environment can support. The result of this Overproduction is that those people who have the highest level of environmental genetic fitness will have offspring who are better able to compete in that environment.
Therefore, Genetic variation, fitness, and adaption are all factors in Darwin's theory of evolution.Overproduction and competition are other crucial components of this process.

In your own words, describe the base-pairing rules in any DNA molecule (Hint: Think about the BFF's)
Answer:
There are four different bases, each of which pairs with only another. Adenine (A) pairs with Thymine (T), and Guanine (G) pairs with Cytosine (C). This rule is universal to all DNA. A good way to remember is apples in the tree (adenine and thymine), cars in the garage (cytosine and guanine) (credit to the Amoeba Sisters)

Which of the following is involved in the opening of stomata for the gas exchange of the plant?
Answer: Osmotic Pressure, lb/in2
Explanation:
Osmotic pressure is involved in the opening of stomata for the gas exchange of the plant.
What are stomata?In the epidermis of tree leaves and needles, there are cell structures called stomata that play a role in the exchange of water and carbon dioxide between plants and the atmosphere.
Transpiration and gas exchange is made possible by stomata. It is surrounded by two guard cells that regulate how the stomata open and close. Stomata open during the day for gaseous exchange and to release water vapour during transpiration. The stomata open and close in response to changes in the turgor pressure within the guard cell.
Hence, osmotic pressure is responsible for the opening and closing of stomata.

All Hawaiian honeycreeper bird species have similar skeletal and muscle structures. However, each Hawaiian honeycreeper species has a bill specialized for eating certain foods. What would a scientist most likely conclude based on this observation? Artificial selection shaped the bill for eating certain foods. Increased genetic variation resulted in similar skeletal and muscle structure. Changes in each honeycreeper species occurred independently, but resulted in similar traits. Honeycreepers arose from a single species that migrated to Hawaii and adapted to different niches over time.
Answer:
The correct answer is - Honeycreepers arose from a single species that migrated to Hawaii and adapted to different niches over time.
Explanation:
All Hawaiian honeycreeper bird species share similar muscle and skeletal structures. This suggests that all Hawaiian bird species arose from a common ancestor and evolved due to different environmental conditions such as eating particular foods for particular species.
It is believed to be a single species of honeycreeper who migrated from the mainland to Hawaiin island and adapted to different niches over time by the process known as natural selection.

What happens when an antibody and antigen react?
Answer:
Antigen-antibody interaction, or antigen-antibody reaction, is a specific chemical interaction between antibodies produced by B cells of the white blood cells and antigens during immune reaction. The immune complex is then transported to cellular systems where it can be destroyed or deactivated.
Explanation:
Antibodies attach to a specific antigen and make it easier for the immune cells to destroy the antigen. T lymphocytes attack antigens directly and help control the immune response. They also release chemicals, known as cytokines, which control the entire immune response.

a. GAC c. UGC
b. CGG d. UGG
2. What process was involved in number 1?
a. Fertilization b. Replication
C. Transcription d. Translation
Answer:
d
Explanation:

c goes with g
The mRNA triplets compliments ACC is UGG and the process involved is transcription.
DNA transcription
DNA transcription is a process carried out by messenger RNA, which has as its ultimate goal the formation of proteins.
This transcription occurs with the combination of nitrogenous bases, which combine in such a way:
C - G
G - C
A - U
T - A
So, the transcription of the ACC base would be equivalent to UGG, and the process is called transcription.

Why do you think
organisms in the
same kingdom are
not all identical?
Answer:
Evolution, mutation, and adaptation
Explanation:
Since different organisms adapt to different environments and receive different mutations, they adapt differently and slowly change. That is why there are different species of birds, just look at the galapagos islands, there are thousands of species of finches that changed to survive on each island. The same could be said for every organism since the early organisms that we evolved from were widespread, some evolved differently than others, leading to different fish, different lizards, different early mammals, and so on. That is why humans look different than dogs or cats, we evolved best to our environment so we could survive.
Answer:
Though they are in the same kingdom which makes them makes the species they are built of different genes received from each parent.

What does it mean if something is pure-breeding for a trait?
Answer:
they want to make sure the animal gets the traits of the parents
Explanation:
Need help. Will give brainliest. Answer all these questions.
Answer:
1. The daughter cells are genetically identical because they each contain the same diploid chromosome complement as the original parent cell. It can be seen in the stages shown above that mitosis maintains the chromosome number or complement of a cell.
2. Much of the growth in an adult is attributed to the growth plate in the bones, which is line of cells at each end of the bone that divides rapidly during puberty. As the bones elongate, the muscles also elongate as they are stimulated to grow by stretching and hormonal changes. When puberty is completed, the growth plate calcifies into solid bone and can no longer grow. Muscles can continue to enlarge with athletic activities and can sometimes split with excessive force, but muscle cells typically do not continue to divide. Cells such as your skin, hair, and interior mucus surface cells continue to divide because they are in direct contact with things from the outside world. Bone marrow also continually divides to produce red and white blood cells. Many other cells in your body do not continue cell division.
3. The number of Chromosomes stay the same when the cell divides because before a cell divides it produces new copies of the Chromosomes in the nucleus so when division takes place two genetically identical 'daughter cells', containing the same genes, are formed.
4. – in cells capable of dividing, the period between cell divisions is called interphase – cells spend most of their time in interphase because this is the phase where they perform their functions (obtaining energy, synthesizing products, repair damage, fight disease, duplicate their genetic material and get ready for division)
5. Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes. The offspring that arise by asexual reproduction from either unicellular or multicellular organisms inherit the full set of genes of their single parent. Asexual reproduction is the primary form of reproduction for single-celled organisms such as archaea and bacteria. Many eukaryotic organisms including plants, animals, and fungi can also reproduce asexually. In vertebrates, the most common form of asexual reproduction is parthenogenesis which is typically used as an alternative to sexual reproduction in times when reproductive opportunities are limited. While all prokaryotes reproduce without the formation and fusion of gametes, mechanisms for lateral gene transfer such as conjugation, transformation and transduction can be likened to sexual reproduction in the sense of genetic recombination in meiosis.
6. Since each of the parent cell’s chromosomes were replicated during interphase, there are two copies of each chromosome in the cell during prophase. Once the chromatin has condensed into individual chromosomes, the genetically-identical chromosomes come together to form an “X” shape, called sister chromatids .
