Name and give examples of 2 major types of mutations. What do they have in common? How are they different?

Answers

Answer:

The correct answer would be - Two major types of mutations are deletions and substitutions.

Explanation:

The two major types of mutations are deletion and substitution, other than these there are many more mutations that are categorized under gene mutations and chromosomal mutation.

The deletion mutation takes place in the conditions where the DNA deletes or missed copying the nucleotide in a new  DNA molecule. This type of mutation can occur in one or more nucleotides. Whereas Substitution mutation occurs when there is a wrong nucleotide added to the DNA sequence or substitute with other.

Both could be deleterious and takes place at the nucleotide level. Both mutation depends on the number of nucleotide or the location of the mutation on the gene.

According to catastrophists what was the rate of geological change?

Answers

Catastrophism is the theory that the Earth has largely been shaped by sudden, short-lived, violent events, possibly worldwide in scope.[1] This is in contrast to uniformitarianism (sometimes described as gradualism), in which slow incremental changes, such as erosion, created all the Earth's geological features. The proponents of uniformitarianism held that the present was the key to the past, and that all geological processes (such as erosion) throughout the past were like those that can be observed now. Since the early disputes, a more inclusive and integrated view of geologic events has developed, in which the scientific consensus accepts that there were some catastrophic events in the geologic past, but these were explicable as extreme examples of natural processes which can occur.

Forensic scientists have been called by police to come to a home. There is a dead body in the living room, which has been found by the victim's dog walker when she entered the home through the back door. The front door was shut and locked, and there is no sign of other forced entry. The dog walker states that a vase is missing from the living room. What would be the best question for the forensic scientists to ask in this situation?

Where is the missing vase?
How did the victim die?
How did the robber get in the house?
Did the dog walker steal the vase?

Answers

Answer:

I think it might be how did the victim die because they might have died of a heart attack or something normal. Then they can start asking where the vase went.

Annisa has a disorder or disease that the doctors found very difficult to diagnose.
Her primary symptom are that her muscles twitch without her control. Then
her metabolism stopped functioning.
Which body systems are working together in this scenario?

Answers

Answer:

Muscular and digestive systems.

Explanation:

Muscular and digestive systems are the body systems which are working together in this scenario because muscular system allows the movement of muscles and digestive system is the system where metabolism of the food occurs. If there is something wrong with the muscular system, the muscles can't perform their function properly while on the other hand, if the digestive system fails to work properly, the metabolism can't happen in our body and our body can be adversely affected.

which of these is a product of photosynthesis and a requirement for cellular respiration? a) carbon dioxide b) glucose c)water d) sunlight​

Answers

Answer:

b.) glucose

Explanation:

Hello There!

These are the products and requirements for both Photosynthesis and Cellular Respiration

For Photosynthesis

What is required: Sunlight, Carbon Dioxide and Water

The products: Oxygen and Glucose

For Cellular Respiration

What is required: Glucose and Oxygen

The products: Water and Carbon Dioxide

Now that we have some background information about the products and what is required lets look back at the question

which of these is a product of photosynthesis and a requirement for cellular respiration?

Out of the answer choices the correct one would be Glucose.

Glucose is indeed a product of photosynthesis and Glucose is also required for Cellular respiration to take place

Answer:

B. Glucose

Explanation:

Cellular respiration begins with Glycolysis, in which an investment of 2 ATPs are needed in order to break a carbon-carbon bond in 1 glucose molecule. When the bond is broken, high energy electrons are released and carried by ___________ to go to the Electron Transport Chain. The resulting carbon compound, pyruvate, will enter the Krebs Cycle. A net gain of 2 ATP are created. However, if oxygen is not readily available to the cell (and the mitochondria), ____________ and pyruvate will enter Lactic Acid Fermentation to free up the ____________ so it can continue accepting high energy electrons from the breakdown of glucose in Glycolysis. This will, in turn, continue to create a small, but steady supply of ATP energy.

Answers

Answer:

1. NADH

2. NADH

3. NADH

Explanation:

Cellular respiration begins with Glycolysis, in which an investment of 2 ATPs are needed in order to break a carbon-carbon bond in 1 glucose molecule. When the bond is broken, high energy electrons are released and carried by NADH to go to the Electron Transport Chain. The resulting carbon compound, pyruvate, will enter the Krebs Cycle (to produce GTP/ATP as well as NADH and FADH₂ which carries electrons to the electron tranport chain). A net gain of 2 ATP are created. However, if oxygen is not readily available to the cell (and the mitochondria), NADH and pyruvate will enter Lactic Acid Fermentation to free up the NADH so it can continue accepting high energy electrons from the breakdown of glucose in Glycolysis. This will, in turn, continue to create a small, but steady supply of ATP energy which is the 2 ATP generated in the payoff phase of glycolsis.

Why do the different genetic types of albinism result in a similar phenotype?​

Answers

Answer:

Why are there different variations of albinism and why it results in the same basic phenotype?

The phenotypic heterogeneity of albinism is due to the different gene mutations affecting various points along the melanin pathway, resulting in varying degrees of decreased melanin production. Additionally, associated developmental changes occur in the optic system as a result from this hypopigmentation.

1.) what is the optimal pH for pepsin? where is pepsin found?

2.) what is the optimal pH for salivary amylase? what substrate does it act on? where is it found?

Answers

Answer: 1. The digestive power of pepsin is greatest at the acidity of normal gastric juice (pH 1.5–2.5). 1.0–2.0

The optimum pH for pepsin activity of 1.0–2.0 is maintained in the stomach by HCl. When the pH of the medium increases to values greater than 3.0, pepsin is almost completely inactivated. 2.  The optimum pH for the enzymatic activity of salivary amylase ranges from 6 to 7. Above and below this range, the reaction rate reduces as enzymes get denatured. The enzyme salivary amylase is most active at pH 6.8.  around 7

Salivary α‐amylase has a short‐lived action. In fact, it is swallowed with chewed food and subsequently inactivated by extremely low gastric pH; amylase in fact has an optimal pH around 7, and the pH of saliva is generally between 6.4 and 7.0.

"Construct an explanation based on evidence for how the principles impact the

process of natural selection"

Answers

Answer:

The principles are responsible for the natural selection of organisms.

Explanation:

The principles greatly impact the  process of natural selection because these principles are responsible for the natural selection of organisms. If the organisms have all the principles of natural selection, it has more chances of survival as compared to other organisms due to the presence of the favourable characteristics. These favourable characteristics helps the organisms to increase in population because the environment is suitable for them or in other words the organisms can tolerate that environment better than other organisms. for example, polar bear survives in the polar regions because they have a thick skin full of hair that helps in the survival on the cold regions, it is an act of natural selection.
