Explanation:
The emmanation of Cells was known about 3.5 billion years ago. The cell is the basic unit of life, in which all living organisms are made up. Robert Hooke in 1665 discovered what we called cell theory today. Alot of scientist worked to the successful discovery of cell such as matthias schleiden,Theodor Schwann and others.
1. robert brown who is botanist as well as a Scottish. in his experiment on plant cell, that small dense round bdy substance were present in the plant cell which he later called nucleous.
2. First to identify and name cells
In the year 1665, Robert Hooke brought about the discovery of cell, he identified cell. However, he was able to identify cell using a microscope where he sees a dead cell which he called cork.
3. Arround 1830s Theodor Schwann who is a botanist and Matthias Schleiden are carrying experiment on tissues after series of experiment they arrived at unified cell theory. and that new cell came u from existing cell.
Theodor Schwann later concluded that all animals are also made up of cells, and that was arround 1839.
4. In the year 1837, Matthias Schleiden discovered that that old plant's cell Nuclei usually form the new cell. However, with series of experiment,
Matthias Schleiden who is German scientist Concluded all plants are made up of cells In 1838.
5. Zacharias Janssen who hails from Dutch, in 1590, co-invented the first microscope with Hans. They are regarded as a spectacle maker. However, the first spectacle was attributed to Italy in 14th century. Anton van Leeuwenhoek was the man that use the microscope to observe specimen in 1675 with a lens.

The first energy-generating steps in glycolysis begin when glyceraldehyde 3-phosphate undergoes an energetically favorable reaction in which it is simultaneously oxidized and phosphorylated by the enzyme glyceraldehyde 3-phosphate dehydrogenase to form 1,3-bisphosphoglycerate, with the accompanying conversion of NAD+ to NADH. In a second energetically favorable reaction catalyzed by a second enzyme, the 1,3-bisphosphoglycerate is then converted to 3-phosphoglycerate, with the accompanying conversion of ADP to ATP. Which of the following statements is TRUE about this reaction?
a. The cysteine side chain on the enzyme is oxidized by NAD+.
b. The energy stored in the phosphate bond of glyceraldehyde 3-phosphate contributes to driving the reaction forward.
c. The ΔG° for the oxidation of the aldehyde group on glyceraldehyde 3-phosphate to form a carboxylic acid is more negative than the ΔG° for ATP hydrolysis.
d. The reaction glyceraldehyde 3-phosphate---->1,3-bisphosphoglycerate should be inhibited when levels of NADH fall.
Answer:
The answer is option B.
Explanation:
It is stated that "the enzyme glyceraldehyde 3-phosphate dehydrogenase to form 1,3-bisphosphoglycerate" which indicates that the energy from the broken bonds of the glyceraldehyde 3-phosphate provides energy for the reaction to take place.
So the correct answer is option B.

In your summary be sure to use at least two of the following terms cells, energy, organism, macromolecules, homeostasis
Answer:B
Explanation:
Answer:
The Grand View College (GVC) 2 focuses on understanding the basic components, structures, and functions of living organisms. This includes exploring the cells, macromolecules, and processes that allow an organism to have homeostasis and to obtain, use, and store energy.
Cells are the basic unit of life and have many complex components and functions. They have specialized membranes and organelles, are capable of moving, and interact with their environment to maintain homeostasis. Understanding how these components work together and the ways they communicate is essential.
Macromolecules, such as proteins and carbohydrates, are responsible for the majority of the work done by cells. A deeper understanding of macromolecules helps one understand how cells interact with the environment and how they use energy.
Energy is vital for organisms to maintain their homeostasis. This energy can come from sunlight, chemical reactions, and respiration. Understanding how these processes interact with the cell’s structure and components can help explain the role energy plays in an organism.
Homeostasis is essential for any organism to remain healthy and function properly. It is the result of a combination of factors, including the cell’s structure, components, and potential hazards in the environment. Knowing how organisms handle these factors is important to understanding their ability to maintain homeostasis.
The GVC 2 is a great way to delve deeper into biologists’ understanding of living organisms. By examining the components, structures, and processes that make up an organism, it becomes easier to understand the role they play in its ability to maintain homeostasis and use energy efficiently.

Explain the relationship between coral and algae, and how a problem with algae photosynthesis caused coral bleaching in the Great Barrier Reef.
The relationship between Coral and Algae and how a problem with Algae photosynthesis caused Coral bleaching in the Great Barrier Reef happens in a way that when Coral reefs become stressed as a result of changes in condition such as the temperature, lights or nutrients,These Coral beef therefore expel the symbiotic algae living in there tissue which they have feeding relationship with, the expulsion of those algae will make them to turn to white completely.
However,warmer water temperatures can give rise to Coral bleaching.
The relationship between coral and algae is mutualism.
There is a mutualistic relationship between corals and algae because both coral and algae provides benefits to each other. The coral provides a protected habitat and raw materials which the algae need for photosynthesis. whereas the algae produce oxygen and remove waste materials from coral.
A problem with algae in the process of photosynthesis caused coral bleaching because warm water restrict algae from photosynthesis which leads to the death of algae which results in the coral bleaching in the Great Barrier Reef so we can conclude that the relationship between coral and algae is mutualism.

Answer: I believe it may be latent heat.
The amino acids in the original partial sequence (N-term-...P-I-E...-C-term) have little to no impact on protein structure and function. However the amino acid sequence near the C-terminal end of the protein is required for normal function. Any amino acid changes in this region of the protein will result in a nonfunctional protein. Given this information, which reversion mutation in the gene would restore the normal function of the protein?
a. Insertion of 2 base-pairs in the region of the proline codon
b. Deletion of 5 base-pairs in the region of the proline codon
c. Deletion of 2 base-pairs in the region of the proline codon
d. Deletion of 1 base-pair in the region of the proline codon
e. Insertion of 1 base-pair in the region of the proline codon
f. Insertion of 4 base-pairs in the region of the proline codon
Answer:
OPTIONS : B,C,E,F
Explanation:
The Reversion mutation in the gene that would restore the normal function of the protein :
All the options given can restore the normal function except options : A and D
For Deletion of 5 base-pairs in the region of the proline codon
Normal sequence 5' - G | CCG | AUC | GAA | CU - 3' while the mutated sequence is : 5' - G | CCG | AUG | AAC | U - 3' . this shows that the removal of the 5 case pairs will only remove 2 amino acids restoring the normal protein in the process and not affect the C terminal of the amino acids and also the reading frame will be restored
normal protein.
For Deletion of 2 base-pairs in the region of the proline codon
The Normal sequence 5' - G | CCG | AUC | GAA | CU - 3' while Mutated sequence 5' - G | CCG | AUG | AAC | U - 3'
This shows that the deleted base pair is from this codon hence removing the two base pairs will lead to the reading frame been restored and also the C terminal amino acids, but this will result to a protein with a less than one amino acid

Explanation:
Annette's maternal grandfather died of Huntington's disease when he was 53 and Annette was 8. Huntington's is a rare autosomal dominant degenerative neural disorder that usually hits people in their late forties, early fifties. Annette loved her grandfather very much and was deeply affected by the painful progression of his disease. She wants to get pregnant but does not want to risk giving birth to a child that will suffer as much as her grandfather. If she tested positive for Huntington's, what is the probability of her first child to develop Huntington's? Of her second child? Of her mother? (Note that since Huntington’s is so rare, you can assume that neither grandmother, nor father or partner have the Huntington’s mutation).
Answer and Explanation:
Huntington disease is caused by a mutation in the gene that codifies for the Huntingtin protein (Htt). The mutation produces an altered form of the protein leading to the neuron´s death in certain areas of the brain.
Huntington disease characterizes for being,
• Hereditary, passing from generation to generation. To express the disease, a person must have been born with an altered gene.
• Autosomal, affecting men and women equally, because the mutated gene is located on an autosomal chromosome.
• Dominant, which means that by getting only one copy of the altered gene coming from any of the parents, the receiving person will express the disease. The mutation in the gene dominates over the normal gene copy.
• Expressed by heterozygosis. Most people affected by the disease are heterozygous, with a normal copy and a mutated copy.
An affected heterozygous person has 50% of chances to give a normal recessive allele or an altered dominant allele. When one of the progenitors is a carrier and the other one is a healthy person, the progeny have 50% of probabilities of inheriting a dominant allele expressing the HD from the affected parent.
In the exposed example, Annette probably is heterozygous, Hh, and she marries a healthy man, hh.
Parental) Hh x hh
Gametes) H, h h, h
F1) 1/2 Hh, 1/2 hh
The probability of the first child to develop HD is 50%, or 1/2
The probability of the second child to develop HD is also 50%
The probability of both children to develop HD is 1/2 x 1/2 = 1/4, or 0.25
Now, Annette´s grandpa had the disease, Hh
Annette´s grandma did not, hh
The probability of her mother to develop HD is 50% because she could just inherit the dominant allele from her father.
Why is cell division important after fertilization?
Answer:
Perhaps most importantly, without cell division, no species would be able to reproduce—life would simply end (or would have ended a long time ago). Every human, as well as every sexually reproducing organism, begins life as a fertilized egg (embryo) or zygote.
Cell division is important after fertilization because it is necessary for growth and multiplication.
CELL DIVISION:
Cell division is the process by which a single cell is duplicated to produce more copies of itself. Fertilization is the process that joins a sperm and egg cell together in sexual reproduction to form the zygote. However, the diploid (2n) zygote needs to grow and multiply. Hence, the zygote formed as a result of fertilization undergoes a form of cell division called mitosis. Therefore, cell division is important after fertilization because it is necessary for growth and multiplication.Learn more at: https://brainly.com/question/3327479?referrer=searchResults

how does density affect refraction?
Answer:
Density of any substance or medium determine the amount of light that will be refracted.
Explanation:
Density of any substance or medium determine the amount of light that will be refracted.
The higher is the density of any medium, the higher will be the number of atom or molecules in a given medium and hence more obstruction will be produced for light. High density also causes high refractive index.
The light usually bends away from the normal when light travels from a region of low to high density and light bends towards the normal when light travels from a region of high to low density

Levi decides to examine the effect of fertilizer on the growth of tomato plants. He chooses four plants for his experiment and applies varying amounts of fertilizer to the three of them. He does not apply fertilizer to one plant. Over a 15-day period, the plants receive fertilizer on Days 1, 4, 7, 10, and 13. Levi measures the height of all of his plants with a meter stick on Days 3, 6, 9, 12, and 15. He also makes sure to hold all experimental factors constant except for the fertilizer. Which statement describes what Levi did to prepare the control group in his experiment?
This question is incomplete because the options are missing; here are the options:
Which statement describes what Levi did to prepare the control group in his experiment?
A) Levi held all experimental factors constant except for fertilizer.
B) Levi did not apply any fertilizer to one of his plants.
C) Levi applied different amounts of fertilizer to three of his plants.
D) Levi measured his plants on five separate days.
The answer to this question is B. Levi did not apply any fertilizer to one of his plants.
Explanation:
In an experiment, the control group refers to the subject or subjects, in this case, the plants, that do not receive the treatment or variable tested by the researcher. This implies the control group for Levi is the plant with no fertilizer because this is the only plant that does not receive the treatment or fertilizer. Moreover, this acts as a control group because Levi can use this plant to determine if the growth of the other three plants is positively or negatively affected by the use of the fertilizer.
Identify EITHER one nitrogen compound OR one phosphorus compound that is considered a pollutant when released by human activity into the environment. For the compound you identified, describe the human activity and a specific environmental problem that results.
Answer:
Sodium tripolyphosphate (STPP)
Explanation:
Sodium tripolyphosphate (STPP) is a compound of phosphorus that is used to manufacture detergent.
This chemical is released into the environment when detergents are used to wash dishes or in laundry.
This compound finds its way into water bodies and leads to overgrowth of algae. This is known as eutrophication.
As these algae die, decomposition of the organisms lead to a drop in oxygen level of water bodies and increase in biochemical oxygen demand. As a result of these, some aquatic species may begin to die or relocate to other water bodies.
3. Briefly summarize in your own words what alternative explanations have been proposed for melanism that do not have to do with bird predation.
Answer & explanation:
Melanism occurs due to a genetic mutation that causes the excessive and concentrated production of the black pigment, called melanin. The consequence is living beings with darkened skin or fur. There are three types of melanism.
Adaptive melanism occurs by the need to adapt to the environment, a condition that will be passed through the generations. This melanism allows animals to camouflage themselves during hunting or to hide from predators.
Industrial melanism is related to human interference, especially industrial activities, in the lives of animals (dark-colored moths are the best-known cases). Air contamination is one of the main factors for this condition.
There is also pseudo-melanism, which partially affects animals and is generally motivated by genetic mutations. In certain species, the characteristic spots and stripes appear larger and darker than usual. This type of melanism is very present in cats such as tigers, cheetahs, leopards. However, other animals can still be affected.
