Answer:
Examination of vertebrate embryos reveals that during corresponding stages of early development,
the embryos appear to be very similar. For example, all vertebrate embryos pass through stages in
which they have gill pouches. The pouches eventually develop into the gill apparatus in fish; in laterevolving vertebrates that do not have gills, the gill pouches undergo further refinement and develop
into structures associated with the head and neck. Similarly, all early vertebrate embryos have tails,
which persist in some animals but regress during the later stages of development of humans. Thus,
the individual development of an animal occurs through a series of stages that paint a broad picture
of the evolutionary stages (phylogeny) of the species to which it belongs.
"Ontogeny recapitulates Phylogeny", Haeckel
Explanation:
sure po ito
Examination of vertebrate embryos well-known shows that in corresponding levels of early improvement, the embryos appear very similar.
For example, all vertebrate embryos by skip thru levels in which they have got gill pouches. The pouches subsequently turn into the gill equipment in fish; in later evolving vertebrates that don't have gills, the gill pouches go through similar refinement and develop into systems related to the pinnacle and neck. Similarly, all early vertebrate embryos have tails, which persist in a few animals however regress at some point in the later levels of improvement of humans.What is ontogeny recapitulates phylogeny?These scientists claimed that ontogeny recapitulates phylogeny (ORP). This word shows that an organism's improvement will take it thru every one of the personal levels of its evolutionary history, or its phylogeny.
Thus, the man or woman improvement of an animal happens thru a chain of levels that paint an extensive picture of the evolutionary levels (phylogeny) of the species to which it belongs.

Why do the different genetic types of albinism result in a similar phenotype?
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.
Explanation:
The graph of a population that is growing exponentially in the absence of limiting factors is
O N-shaped.
O S-shaped

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?
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"
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.
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?
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.

Distinguish between natural selection and artificial selection.
Answer: Natural selection is based on the adaptive characteristics of animals. Artificial selection is based on the desirable characters selected by humans. Only beneficial or favorable traits are inherited over the successive generations by natural selection. Natural selection is performed on all the types organisms; Artificial selection is processed on some selective organisms of humans desires. ... Natural selection results in the transformation of the entire population of a species; Artificial selection brings out the new variety of that species.
Explanation:
Answer:
answer in explanation
Explanation:
Natural selection occurs over a long period of time and happens naturally. artificial selection happens relatively fast and occurs when humans choose a certain trait they like and help the animal with that trait reproduce.

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?
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.

1. Deoxyribonucleic Acid
2. In biology, a gene is a basic unit of heredity and a sequence of nucleotides in DNA or RNA that encodes the synthesis of a gene product, either RNA or protein. During gene expression, the DNA is first copied into RNA.
3. nucleus
Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA).
4. As described above, DNA can be found in three organelles: the nucleus, mitochondrion, and chloroplast. Only eukaryotes have a nucleus, which is a large structure that's surrounded by a membrane. Nuclear DNA comes in the form of long, linear pieces of DNA called chromosomes.

Look at the speedometer at the top. What do you notice about the speed when the skater goes from a height of 6m down to 0m and back up to 6m?
Answer:
First increases then decreases.
Explanation:
The speed of skater tends to increases when it moves from high elevation of 6 m to the low height area due to sloppy region while on the other hand, when the skater moves again from 0 m or from the ground level to 6 m height its speed decreases when reaches to the highest point. First the speed of the skater increases due to moving in the direction of gravity while on other hand, the speed of the skater decreases due to movement of skater against the gravity of earth.
