The cell cycle phases in order consist of interphase (divided into G1, S, and G2 phases), followed by the mitotic phase which includes mitosis (with stages prophase, prometaphase, metaphase, anaphase, and telophase) and concludes with cytokinesis.
Explanation:Phases of the Cell Cycle
The cell cycle is an ordered series of events involving cell growth and cell division that result in two new daughter cells. The cycle can be divided into two main components: interphase and the mitotic phase. Interphase itself consists of three stages:
G1 phase (first growth phase): The cell grows in size and the number of organelles doubles.S phase (synthesis phase): DNA replication occurs, creating an identical copy of the cell's DNA.G2 phase (second growth phase): Proteins needed for cell division are synthesized and the cell prepares for mitosis.The mitotic phase follows interphase, beginning with mitosis (karyokinesis), which includes the stages: prophase, prometaphase, metaphase, anaphase, and telophase. Finally, cytokinesis occurs, where the cell's cytoplasm is divided, concluding the cell cycle and resulting in two genetically identical daughter cells.

what is the history of camera??
Answer:
begins even before the introduction of photography
Explanation:
cameras evolved from the camera obscura though many generations of photographic technology
Final answer:
The history of the camera dates back to the camera obscura utilized since the 16th century. Significant advancements occurred with Nicéphore Niépce's light-sensitive surface in the 19th century, followed by Daguerreotype and the introduction of photographic film. These innovations led to widespread accessibility of photography and the dawn of the motion-picture era.
Explanation:
History of Camera:
The history of the camera can be traced back to the camera obscura, a device used since the 16th century to project images of external scenes. The camera, derived from the Latin 'camera obscura' meaning 'dark chamber', evolved significantly with French inventor Joseph Nicéphore Niépce's creation of a light-sensitive surface in the 19th century. This discovery marked the beginning of modern photography.
Photography developed rapidly in the mid-19th century when Nicéphore Niépce successfully photographed images with a camera, but his early attempts required days of exposure. His colleague Louis Daguerre improved this process with the invention of the Daguerreotype, which significantly reduced exposure time and enhanced image clarity. The introduction of the Daguerreotype in 1839 is often regarded as the birth of practical photography.
Photographic technology advanced further when George Eastman invented photographic film in 1884. The Kodak #1 camera in 1888 and the Kodak Brownie camera by 1900 broadened photography's accessibility to a wider audience. With these developments, including motion-picture cameras and the birth of cinema, photography's impact on society and the arts has been profound and continues to evolve today.

Explanation:
Two different species are discovered in the rainforest and their DNA sequences
are 94% the same. What does this similarity suggest ?
The similarity of 94% in their DNA sequence suggest that they have originated from a common ancestor and are closely related species.
Explanation:
The difference in DNA sequences in different species is due to the accumulation of genetic variation in the course of natural selection and evolution. Less is the difference in DNA sequences of two organisms the more related they are.
Genes determine the characteristics in an organism, and they are DNA sequences determining the protein to be formed. The similarity in DNA sequence of two species establish the evolutionary relationship among them.
Due to the genetic variation in species, the natural selection of the species had caused the evolution of the species adapted well to the environment.

What key reactant is needed to drive cellular respiration
Answer:
Glucose and Oxygen are the key reactant that is needed to drive cellular respiration. Respiration is a energy releasing process in which energy is released due to the breakdown of glucose molecules with the help of oxygen which produces carbondioxide, water and energy in the form of Adenine tri phosphate (ATP). Carbondioxode is a waste product which is removed from the cell and ATP is used by the cell for performing different functions.
When a mustard plant seedling is transferred to an environment with higher levels of carbon dioxide, the new leaves have a lower stomata-to-surface-area ratio than do the seedling’s original leaves.
Which of the following best explains how the leaves from the same plant can have different stomatal densities when exposed to an elevated carbon dioxide level?
Answer:
When higher levels of carbon dioxide is present in the environment and a mustard plant seedling is transferred to an environment, the new leaves have a lower stomata-to-surface-area ratio, it is because the concentration of carbondioxide is high in the surrounding so the plant produce small leaves having less number of stomata. If the concentration of carbondioxide is lower so big leaves are produced having maximum number of stomata.

C)divergent evolution
D)continental drift
Answer:
The correct option is A.
Convergent evolution is one of the defined type of evolution and it is shown by the species belonging to different ancestors show similar characteristics due to the same residing environmental condition.
Explanation:
The creation of analogous structure takes place in the process of convergent evolution. This is illustrated by the occurrence of similar structure in two different species which were not observed in their respective ancestor. This is due to the residence of the associated species in the same environmental condition and facing the same problems of livelihood. One of the most common example is the flying ability of the insects, bats and birds.
What is the difference between chromatin and chromosomes?
Answer:
The main difference between chromatin and chromosome is that chromatin consists of the unravelled condensed structure of DNA for the purpose of packaging into the nucleus whereas chromosome consists of the highest condensed structure of the DNA doublehelix for the proper separation of the genetic material between daughter cells.
Chromatin is the combination of DNA and proteins that make up chromosomes. Chromosomes are condensed during cell division but exist as less condensed chromatin when the cell is not dividing.
To understand chromatin, it is helpful to first consider chromosomes. Chromosomes are structures within the nucleus that are made up of DNA, the hereditary material, and proteins. This combination of DNA and proteins is called chromatin. In eukaryotes, chromosomes are linear structures. For example, in humans, the chromosome number is 46, whereas in fruit flies, the chromosome number is eight.
When a cell is not dividing, the chromosomes are in a less condensed, thread-like form known as chromatin. During cell division, chromatin condenses to form distinct chromosomes that are visible under a microscope. Therefore, chromatin describes the material that makes up chromosomes both when they are condensed and decondensed.

How are dna and genes related to chromosomes?
The answer is D. Chromosomes contain genes, and genes are made of DNA
DNA consists of genes that contain instructions to build proteins and are organized into large structures called chromosomes.
DNA (deoxyribonucleic acid) is a helix-shaped molecule comprised of nucleotide base pairs that contain the genetic blueprint of an organism. It is found within structures known as chromosomes, which are made of tightly coiled DNA and proteins called histones. Genes are specific segments of DNA that carry the instructions for making proteins, which perform a vast array of functions within an organism. Each chromosome contains many genes, and these are organized in a specific sequence that is largely the same across individuals of the same species. For example, all humans have chromosomes with the same genes in the same order, although they may have different variations of those genes known as alleles.
Humans typically possess 23 pairs of chromosomes, with one set inherited from each parent. The egg and sperm cells each contribute 23 chromosomes. Chromosomes are involved in heredity, with genes being the basic units of inheritance that dictate specific traits such as eye and hair color.

"The energy necessary to perform this function comes directly from the
(1)exchange of H2O and O2 during respiration
(2)blood flowing through the organs
(3)ATP molecules produced during cellular respiration
(4)water that is eliminated by the organs"
The energy needed for biological functions comes from ATP molecules produced during cellular respiration (Option 3), involving the digestive, cardiovascular, and respiratory systems.
Explanation:The energy necessary to perform functions in living organisms mainly comes from ATP (adenosine triphosphate) molecules produced during cellular respiration (Option 3). Cellular respiration is an intracellular process that converts glucose and oxygen into carbon dioxide, water, and most importantly, ATP. This process requires the involvement of the digestive, cardiovascular, and respiratory systems. Digestion breaks down food to obtain glucose, while the respiratory system facilitates the exchange of gases, providing oxygen to the body and expelling carbon dioxide. ATP then is used as the main energy source for various biological processes.
