Possible variations of a gene that controls a specific trait
A) Heredity
B) Phenotype
C) Gene
D) Allele
Answer:
D
Explanation:
Alleles are the different possibilities for the trait (brown, blue, green.)
Possible variations of a gene that controls a specific trait are referred to as alleles. Therefore, the correct option is D.
Alleles are different types or forms of a gene that reside at the same locus on a certain chromosome. They contribute to the wide variety of traits seen within populations and can exist in several forms, such as dominant or recessive.
For example, there may be alleles for blue eyes, brown eyes, or green eyes, for a gene that affects eye color. Different alleles play a role in the variety of phenotypes (observable characteristics) that people can display.
Therefore, the correct option is D.

Fossil A is found closer to the surface compared to Fossil B. Which of the following conclusions can be made based on this
statement? (1 point)
Fossil B is most likely older than Fossil A.
O The species of Fossil A existed at the same time as the species of Fossil B.
The species of Fossil A evolved from the species of Fossil B.
O Fossil A is from an older species than Fossil B.
Answer:
Fossil B is most likely older than Fossil A
Explanation:
Fossil B was found deeper in the ground than Fossil A.
If I drop a bone in soil, over time it will settle deeper and deeper down in the earth's surface.
The species of Fossil A is could not have evolved from Fossil B because evolution is not real. The fossil record shows absolutely 0 evidence of evolution over time. All organisms did not come from one cell, they were created individually. If evolution was real wouldn't we see change in humans over time? Wouldn't we see new species popping up everywhere we look? Just because species look the same does not mean that they evolved from one another. For example, if you were creating 10 different species of animals for yourself, and you had a plan that they would all have a pair of eyes and be able to see, wouldn't you put eyes in all of your creations?
Fossil A could not be older than Fossil B because it has settled for a shorter period of time, and is higher up to the surface.
If the two species existed at the same time, they would be at equal heights in the soil.
This leaves only Fossil B to be older than Fossil A which would explain settling over time causes the older fossil to be deeper in the earth.

Why are proteins so small but so important to living organisms .
Explanation: because carry out all the functions in the human body necessary for living. Proteins make up hormones that are required for living. Insulin - responsible for stabilising blood sugar. Haemoglobin - responsible for carrying oxygen around the body. Melatonin - responsible for helping us get to sleep. Adrenalin - responsible for the flight-fight-freeze response. There are many more but here are just a few.
Answer:
Protein is a nutrient your body needs to grow, as well as to support and maintain your life. ... For example, proteins help cells develop and communicate, act as enzymes and hormones, conduct the transport of nutrients throughout your bloodstream and repair damaged tissue. In other words, you can't live without protein.
Explanation:
The principal enzyme involved in DNA replication is called _____________. The enzyme joins ________________ to synthesize a new _______________ strand of DNA. DNA replication is called ______________ because each new DNA molecule is made up of one original and one new strand.
complementary
DNA polymerase
nucleotides
semiconservative
Answer:
The principal enzyme involved in DNA replication is called _DNA polymerase_. The enzyme joins _nucleotides_ to synthesize a new __complementary_ strand of DNA. DNA replication is called __semiconservative__ because each new DNA molecule is made up of one original and one new strand.
Explanation:
DNA replication is the process through which DNI molecule duplicates. This event takes place during the S stage of the interphase. So when the cell divides during mitosis or meiosis, each cell will get a complete set of chromosomes.
DNI replication is semi-conservative because each new molecule carries an original DNI strand and a new one. The fact that the new molecule is composed of an original strand makes it semi-conservative. The old existing strands are used to synthesize the new complementary strand.
The origin of the replication requires helicase enzymes to break hydrogen bonds and separate the two original strands. The topoisomerase enzyme is necessary to release tension. Other proteins are also needed to join the strains and keep them separated. Once the molecule is opened, there is a region named replication forks. DNA polymerase makes the new nucleotides enter into the fork and pairs them with the corresponding nucleotide of the original strand. Adenine pairs timine, and cytosine pairs guanine.
DNA strands are antiparallel, and replication occurs only in 5´-3´direction. So one of the strands will replicate continuously, while the other strain will be formed by short fragments known as Okazaki fragments.
Primers are needed to make the DNA polymerase work. Primers are small units of RNA and are placed at the beginning of each new fragment.

Put the following layers of the digestive tract wall in order from the lumen to the deepest layer: 1. lamina propria 4. digestive (mucous) epithelium 2. muscularis externa 5. serosa 3. submucosa 6. muscularis mucosae
Answer:
4. digestive (mucous) epithelium
1. lamina propria
6. muscularis mucosae
3. submucosa
2. muscularis externa
5. serosa
Explanation:
The first layer of the digestive tract, starting from the lumen, is the epithelium. This has different characteristics depending on the digestive tract section. Then there is a loose connective tissue called lamina propria. Next, there is a layer of muscle called muscularis mucosae. It is only present in the digestive mucosae. The next layer is the submucosa, which has dense connective tissue and the submucosal plexus. Then it follows the muscular externa, which has muscle, and it is in all the digestive tract except for the esophagus and stomach. Lastly, we have the serosa layer.

2. A (glaciation)
3. B (the appearance of a particular organism)

i. C
ii. D
iii. B
iv. A
Explanation:
1. Pioneer species in succession refers to species that first colonize a barren land or rock. They include species that can adapt to the condition of the land and subsequently break it down for other organisms to grow. Pioneer species in primary succession include ferns, lichens etc.
2. Primary succession occurs as a result of effects or negative impacts on an area. Specifically, primary succession in an area of Alberta today occurs because of the effects of GLACIATION, which is the covering of land surface with ice.
3. The appearance of a particular organism such as pioneer species in an aquatic succession can be an indicator of primary succession.
4. * Humus is an organic component of soil that is produced from decomposed organisms.
* Primary succession is the process of changing an environment from bare rock and a few species to a complex community with many species.
* Pioneer species are simple and hardy plants that first colonize a barren ground or rock.
* Climax community is a stable community that results from the process of succession.

Chloroplast
Nucleus
DNA
Answer:
DNA
Explanation:
Answer:
Explanation:
Los cloroplastos son los orgánulos celulares que en los organismos eucariotas fotosintetizadores se van ocupando de la fotosíntesis. Están limitados por una envoltura formada por las dos membranas concéntricas y contienen muchas vesículas, los tilacoides, donde se encuentran organizados los pigmentos y demás moléculas que convierten la energía lumínica en energía química, como la clorofila.
El término cloroplastos sirve alternativamente para designar a cualquier plasto dedicado a la fotosíntesis, o específicamente a los plastos verdes propios de las algas verdes y las plantas. Aunque el reciente descubrimiento adiciona a más individuos en la lista, como lo es en el caso de Elysia chlorotica, que al digerir al alga Vaucheria litorea, adquiere los cloroplastos a sus tejidos, y gracias a esto, puede realizar la fotosíntesis.
