Hypoxia is known to cause a disruption of somitogenesis. If a mouse embryo were temporarily exposed to low levels of oxygen during the final stages of somitogenesis, what would you expect to see in the vertebral column of the newborn mouse

Answers

Answer 1

In mammals, hypoxia may cause defects during fetal development. In this case, it would be expected to observe an abnormal development of the caudal (tail) vertebrae

Somitogenesis refers to the process during embryo development in which somites form. These somites are cells that will give rise to structures associated with the vertebrae body plan. Somites form sequentially from the head to the tail, where each new somite forms on the caudal or tail region of the previous one.

Somitogenesis represents the first sign of segmentation of the developing vertebrate embryo. During somitogenesis, the unsegmented paraxial or presomitic mesoderm in the trilaminar embryonic stage is segmented in order to form pairs of somites. Moreover, caudal vertebrae refer to the bones that form the tail of vertebrates, which derive from caudal somites.

Embryo hypoxia refers to the condition in which the developing embryo does not receive sufficient oxygen (O2) supply. It has been shown that hypoxia during embryo development can increase the incidence of malformations. In this case, embryo hypoxia affects normal caudal somite segmentation, thereby leading to defects in the caudal (tail) vertebrae.

The layers are formed due to difference of density of solutions.

The main cause of the order of the layers is the difference of weight and density of different liquids in the container. The liquids that has more weight means higher density will sink below the liquids that has less weight means lower density so due to difference in  their density corn syrup is located at the bottom due to higher density and rubbing alcohol is present at the top of the container due to lower density.

https://brainly.com/question/24277427

What caused the order of the layers can be attributed to the densities of the liquids.

The density of a substance is an indication of how heavy the substance is in relation to its volume. Mathematically, it is given as mass/volume.Hence, a liquid with a higher density will always be at the bottom of a liquid with a lower density provided that both of them are of the same volume.

In order words, immiscible liquids poured together in the same container will separate out according to their densities - starting with the highest density liquid occupying the bottom with the lowest density liquid staying topmost.

Which statement explains why athletes experience a burning sensation in
their muscles after vigorous exercise?
A. Their muscles have taken in too much oxygen.
B. The conditions in their muscles have become anaerobic.
C. The temperature in their muscles has become too high.
D. Their muscles have become flooded with glucose.

Answers

Answer:

B. The conditions in their muscles have become anaerobic.

Explanation:

In humans, cellular respiration occurs naturally in an aerobic condition (presence of oxygen) but anaerobic respiration can be adopted in specific or extreme cases. One of those cases is after or during a VIGOROUS EXERCISE.

What happens is that, after a vigorous exercise by an athlete, oxygen becomes insufficient in their muscle cells due to high consumption. Hence, their muscle cells switch to anaerobic respiration (lactic acid fermentation), which causes the build up of lactate in the muscle tissues. This lactate build up cause athletes to experience a painful and burning sensation in their muscles.

Hence, it all begins when "conditions in their muscles become anaerobic after an exercise".

Explanation:

Dispersion refers to the change in an organism's range or distribution area. Different ecological and biogeographical processes might be involved in organisms' dispersion. The term "jump dispersion" refers to a few individuals in a short time that can cross a barrier and occupy a new area. In this situation, the establishment is not always for sure. For this to happen, they must reproduce and start a new population of a certain size that can survive the new conditions.  

Biologic Invasions refer to new species that establish in a new area far or out of their original distribution range. Once established, these species might be considered exotic or invasive, according to their reproductive rate, population growth, and interaction with native species.

The exotic species is the one that has been introduced and got to establish, but causes no damage or alteration to native ecosystems.

The invasive species is introduced into a new area, establishes, expands its distribution from the first invaded spot, and overgrows. As they expand, they compete with other native species for resources such as water, place, radiation, exposure, shelter, source of food, among others. Species are considered to be invasive because of their reproductive rate, population growth, and interaction with native species, which provokes huge damages to the native ecosystem.

It is very common for these species to escape and start new populations in the new area, where they have less environmental pressure and better conditions than in their origin area -fewer predators, more resources, better nitches-, and these factors favor their establishment.

There are some typical steps in an invasion process:

1) Introduction or dispersion to the new area,

2) Naturalization. The new species establishes in the new area. It can grow, reproduce and make use of resources.

3) Overgrowth and uncontrolled expansion.  

4) Interaction with other species.  

5) Stabilization.  

Biologic invasions are natural processes, that occur in small groups of individuals that can expand to other ecosystems. Their expansion is promoted by the appearance or disappearance of barriers.  But these biological invasions have been accelerated by human beings, referring to this as human-assisted invasions. These are the cases in which men transport species from one place to the other for different uses or purposes.

Once a species has become invasive, it turns very hard to eliminate it, especially because it requires big mechanical and economical effort. However, they can be controlled to avoid their wider expansion. There are different ways of controlling invasive species

Answers

Answer:

B. The apple orchard releases toxic chemicals into the water of the  bay.

Explanation:

Option B is the correct answer. It is the most likely explanation for the results in the graph.

From the graph, we can see that the population of the fishes sharply dropped. Since the fertilizer is applied to the apple orchard and the orchard was planted beside the bay, during the rain it is possible that the water has washed some of the fertilizers into the bay. The chemicals used in making fertilizer are harmful and toxic.

This reveals that the toxic chemicals released from the apple orchard are responsible for the decline in the population of the fish.

Sigmoidal plots of activity versus substrate concentration are exhibited by a. holoenzymes. b. Michaelis-Menten enzymes. c. allosteric enzymes. d. monomeric enzymes. e. isozymes.

Answers

Answer:

The correct answer is C

Explanation:

Allosteric enzyme is an enzyme that has more than one active site on the surface of the enzyme. Generally, the binding to one of these active sites affects the affinity of the other active sites on the enzyme; this causes the enzyme not to follow the Michaelis-Menten's enzyme kinetics. Thus, when the activity versus substrate is plotted on a graph, a sigmoidal curve shown instead of an hyperbolic curve (like other enzymes).  

Most carbohydrates manufactured in leaves and other photosynthetic parts are transported through the phloem to the rest of the plant by the process of translocation. osmosis. transpiration. receptor-mediated transport. turgor pressure.

Answers

Answer:

Translocation

Explanation:

Translocation is the movement of sugar that is produced by the source( i.e the part of plants where sugar is produced for other plant parts which could be leaves) to the sinks( i.e the active growing parts of plants where sugar is been deposited for use) where it is used up.

Translocation is done through the phloem tissue to sinks. Sinks could include leaves, fruits, shoots, young developing seeds, tubers and stems.

Translocation is done through the pressure flow model where concentration of sugar that is high at the source creates a low solute potential which helps water movement into the phloem from the adjacent xylem. This movement creates a high pressure potential in the phloem that produce the movement of phloem sap by bulk flow from source to sink.
