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.

Answer:

Geotropism is the influence of gravity on plant growth or movement. Simply put, this means that roots grow down and stems grow up. ... In this case, the stimulus is gravity. Upward growth of plant parts, against gravity, is called negative geotropism, and downward growth of roots is called positive geotropism.

Answer: Both DNA and RNA have four nitrogenous bases each—three of which they share (Cytosine, Adenine, and Guanine) and one that differs between the two (RNA has Uracil while DNA has Thymine). ... One of the most significant similarities between DNA and RNA is that they both have a phosphate backbone to which the bases attach.

Explanation:

Hope i could help please give brainliest i would apreciate it!

Answer: They both have suga-phosphate backbone. They are made up of monomers called nucleotides.

Explanation: Nucleotides are monomeric units of nucleic acids. Nucleotides are made up of three parts: the pentose (5-carbon) sugar, a phosphate group and a nitrogenous bases. Both DNA and RNA have four nitrogenous bases but the only difference is that DNA contains Thymine while RNA contains Uracil. They both have adenine, cytosine and guanine in common. The sugar-phosphate backbone forms the rail of both DNA and RNA, each having a pentose-phosphate group but the difference is that DNA contains deoxyribose while RNA contains ribose sugar.

PLATO AND EDMENTUM PEOPLE your answer is:

134/200

Explanation:

The expression represents the correct way to calculate the frequency of the dominant allele is 134/200.

A Dominant allele may be defined as a type of allele that significantly produces the identical phenotype whether its paired allele is identical or different.

The frequency of the dominant allele can be calculated by the following formula:

[tex]\frac{2 * Number of dominant individual + Number of heterzygote individuals}{2 * Total number of individuals}[/tex]

=  [tex]\frac{2* 50 + 34}{2*100}[/tex]

= 100 +34/200 = 134/200.

Therefore, the expression represents the correct way to calculate the frequency of the dominant allele is 134/200.

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.

Answer:

C

Explanation:

The girls should be sure all other conditions remain constant throughout all three groups to get a valid result. The correct option is C.

The accuracy with which a method measures what it is intended to measure is referred to as its validity.

If research has high validity, it produces results that correspond to real physical or social properties, characteristics, and variations. One sign that a measurement is valid is high reliability.

The consistency of a measure is defined as whether the results can be reproduced under the same conditions.

The validity of a research study refers to how well the findings among study participants correspond to true findings among similar individuals outside of the study.

This definition of validity applies to all clinical studies, including those on prevalence, associations, interventions, and diagnosis.

To make it a valid result the girls should keep a constant condition throughout the experiment to get out a positive result.

Thus, the correct option is C.

7. A nerve signal from the brain arrives at the intersection of the nerve and muscle cells and releases acetylcholine from the neuron. This triggers chemical changes in the muscle cell involving ions, including Ca2+. Calcium triggers the thick filaments, made of myosin, to attach to the thin filaments, made of actin, in the muscle cell, and the myosin pulls the actin toward the center of the muscle cell. ATP causes the release of the actin fibers, allowing the muscle to relax and the process to begin again.

The energy needed for biological functions comes from ATP molecules produced during cellular respiration (Option 3), involving the digestive, cardiovascular, and respiratory systems.

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.

The bionic pancreas assists in maintaining homeostasis by regulating blood sugar levels to normal through the administration of insulin, but it does not cure diabetes.

Explanation:

According to the passage, the bionic pancreas makes corrective actions that return blood sugar levels back to normal. This artificial device helps maintain homeostasis by adjusting the amount of insulin in response to the blood glucose levels, similar to how natural pancreatic function maintains blood sugar levels through the secretion of insulin and glucagon. This bionic device works to regulate blood sugar levels, but it does not cure diabetes, produce more sugar, or break down blood cells.

Answer:

D. Fossil fuel

Explanation:

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.

Bacterial Disease:

Common name : Typhoid

Scientific Name: Typhi

History About disease:

Typhoid can be described as an acute illness which is caused by the bacteria: Salmonella enterica serotype Typhi.

Typhoid fever was responsible for a widespread plague in Athens in 430BC. This outbreak proved to be fatal for one third of the population of Athens. It is difficult to determine the cause of plagues and infectious diseases in early history, although some speculation is usually allowed.

Jamestown, an English colony in Virginia, is also thought by some historians to have died out as a result of typhoid fever. The fever proved fatal for more than 6000 settlers between 1607 and 1624, and may have been responsible for eliminating the entire colony.

Military and war environments have often been subjected to the presence of typhoid fever throughout history. In excess of 80,000 soldiers died as a result of typhoid fever or dysentery in the American Civil War. Likewise, the Spanish-American War led to infections with typhoid both on the field and in training camps.

Answer No 2:

The bacteria that cause typhoid fever spread through contaminated food or water and occasionally through direct contact with someone who is infected.The majority of people in industrialized countries pick up typhoid bacteria while traveling and spread it to others through the fecal-oral route.

This means that Salmonella typhi is passed in the feces and sometimes in the urine of infected people. You can contract the infection if you eat food handled by someone with typhoid fever who hasn't washed carefully after using the toilet. You can also become infected by drinking water contaminated with the bacteria.

Typhoid vaccine is used for the eradication of typhoid.

Answer No 3:

Name: Ebola

Scientific name: Zaire ebolavirus

Ebola is thought to first occur in Sudan in 1976. Ir infected over 248 people.  the second Ebola virus emerged from Yambuku, Zaire, Ebola-Zaire (EBOZ).The third strain of Ebola, Ebola Reston (EBOR), was first identified in 1989 when infected monkeys were imported into Reston, Virginia, from Mindanao in the Philippines. Since then, the virus has been infecting people from time to time, leading to outbreaks in several African countries.

Answer No 4:

Ebola isn’t as contagious as more common viruses like colds, influenza, or measles. It spreads to people by contact with the skin or bodily fluids of an infected animal, like a monkey, chimp, or fruit bat. Then it moves from person to person the same way. Those who care for a sick person or bury someone who has died from the disease often get it.

Other ways to get Ebola include touching contaminated needles or surfaces.

You can’t get Ebola from air, water, or food. A person who has Ebola but has no symptoms can’t spread the disease, either.
