Answer:
Looks like the best answer would be D
Explanation:
You are working in a lab trying to identify a new organism. It looks like a plant, but it could be a fungus. Which of the following tests would NOT be useful in determining which it is?
A. Testing to see if part of the organism grows underground
B. Testing it for Chloroplasts
C. Testing it to see if it absorbs food from the soil
D. Testing it for Chitin
Testing to see if part of the organism grows underground would not be useful in determining whether it is a plant or a fungus.
How other tests would help in determining the organism?Testing it for chloroplastsPlant and green algal cells have a structure called a chloroplast, which is where photosynthesis takes place.A plastid is a sort of body that is formed like a disk, an oval, or a circle and is used to synthesize and store food. Chloroplasts are one type of plastids. The green color of chloroplasts sets them apart from other types of plastids.If the given organism shows a positive test for chloroplast then it is a plant otherwise fungus.Testing to see if it absorbs food from the soilAlmost the majority of the water and nutrients consumed by terrestrial plants are taken up by their roots from the soil.Therefore if the given organism absorbs nutrients from the soil then it is a plant.Testing it for ChitinMost fungi, contain chitin. Alpha-chitin makes up the majority of these fungi's cell walls.If the given organism shows a positive test for chitin then it is a fungus.

Muscle cells contract using ATP. There is little ATP in your blood stream. How do your muscle cells get ATP they need to contract and move you?
Answer: Aerobic ATP Production
Explanation: During everyday activities and light exercise, the mitochondria of muscle fibers produce ATP in a process called aerobic respiration. Aerobic respiration requires the presence of oxygen to break down food energy (usually glucose and fat) to generate ATP for muscle contractions
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

Answer:
Decide which image you would include in a yearbook project about Elizabeth Cady Stanton. Tell what text you would write to go with the image, and explain why you selected the image
To answer that question I said that: I would pick the second picture because it shows a close up view of just her and so it wont be confusing because the other picture had two people.
I prefer the second image of Elizabeth Candy Stanton in a yearbook project. The image determines her leadership towards the women's rights movement.
Who is Elizabeth Candy Staton?
She was an American writer and activist who was a leader of the women's rights and suffrage movement in the U.S. She formulated the agenda for women's rights that guided the struggle well.
Stanton changed the social and political landscape of the United states of America by providing rights for women and slaves.
She established the National Women's Suffrage Association (NWSA) whose main goal is to secure the vote for women and supported a variety of reforms that aimed to make women equal members of society.
The word suffrage means the right to vote Women in the United states fought for suffrage since Andrew Jackson's presidency.
I preferred the second image because it depicts the dedication of Elizabeth to provide equal rights to women as men.

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
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.

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.

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

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.

1. Identify the layer of the atmosphere that is constantly being hit by photons, has very low pressure, and temperatures that decrease from 120° Celsius to -80° Celsius as you move down through the layer.
Answer:
Mesosphere
Explanation:
The Mesosphere is a layer of the atmosphere that is above the Stratosphere and below the Thermosphere. This is the third layer of the atmosphere. Some of its characteristics include;
1. It is constantly being hit by photons: These photons are in the form of meteors that constantly hit this layer of the atmosphere. Meteors which are particles of dust release light energy that makes them visible to the human eyes as shooting stars.
2. The layer is characterized by very low pressure. This makes the air here thin and as the altitude increases, the air becomes very cold.
3. Temperatures decrease from 120° Celsius to -80° Celsius as you move down through the layer: The temperature in this layer decreases as the altitude increases.
