In feedback inhibition, does an enzyme’s substrate attaches to an allosteric site?
Answer:
They bind to an allosteric site which induces a conformational change that increases the affinity of the enzyme's active site for its substrate. This increases the reaction rate.

hypothesis stated: the density of a liquid affects properties and how it interacts with other liquids.
How does density affect the position of a liquid relative to other liquids?
Answer:
The density of a liquid is shown by the object sinking or floating. Therfore, using this information if the object sinks then the object is more dense than the object that floats. When it comes to the density of liquids if the liquid sits on top of the water and does not mix, the liquid is less dense than water. If the liquid sinks into the water and the water sits on top, the liquid is more dense than the water.

Suggested evidence of natural selection at work in humans is the observation of Select one: a. low hemoglobin levels despite high elevation in Tibetan populations over generations b. increase in hemoglobin level when the average person travels from low to high elevation c. an increase in body fat in preparation for winter months at high elevation d. increase in muscle mass from extensive weight training over several months e. mountaineers using oxygen tanks when climbing at high altitude
Answer:
a. low hemoglobin levels despite high elevation in Tibetan populations over generations.
Explanation:
Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.
Simply stated, natural selection entails the survival of the fittest. Therefore, the species that are able to adapt to the environment will increase in number while the ones who can't adapt will die and go into extinction.
A suggested evidence of natural selection at work in humans is the observation of low hemoglobin levels despite high elevation in Tibetan populations over generations. This is as a result of a low level of oxygen in the blood of a living organism such as humans.

The root system of a grass plant interacts with the vascular system to increase the ability of the plant to Group of answer choices
a.absorb carbon dioxide for photosynthesis
b.manufacture pigments for protection
c.obtain nutrient molecules
d.carry on gas exchange and absorb inorganic substances
The root system of a grass plant interacts with the vascular system to increase the ability of the plant to obtain nutrient molecules. That is option C.
Importance of the root systemThe plant is made up of the root and the shoot systems which continually communicates for the growth and maintenance of the whole plant.
The root system is part of the plant that grows downwards. It has the following functions:
It holds the plant to the soil.It absorbs water and nutrients from the soil.It Conducts absorbed water and nutrients to stemTherefore, the root system of a grass plant interacts with the vascular system to increase the ability of the plant to obtain nutrient molecules.

The principle of natural selection states that the best adapted organisms are most likely to survive and reproduce. Was this demonstrated in your experiment? Explain.
Answer:
Yes
Explanation:
Natural selection was first postulated by Charles Darwin. It is the idea that organisms that are best adapted to their environment are able to survive and reproduce thereby transmitting their favorable characteristics to their offspring.
In our experiment, the insects that were able to survive were allowed to reproduce thereby transmitting their favorable characteristics to their offspring. This is a demonstration of natural selection.

Explanation:
In the pictures above, someone is holding ice cubes; it feels cold and they begin to
melt. Which of the following describes what is occurring?
Answer:
As shown in the pictures above, the ice is absorbing heat energy from the hand and the surroundings, which results in the melting of the ice- a process of change of state from solid to liquid. The hand feels cold .
Note: The question is incomplete as it is lacking some details.
Explanation:
Melting is a change of state process which involves the change from solid to the liquid state. Solids when they absorb heat, change to liquids at a temperature known as the melting point. This change of state occurs because the molecule of the substance acquires enough energy which to be able to overcome the intermolecular forces holding the ice crystals together, as a result, the molecules begin to melt.
In the picture,the melting of the ice held by the hand is because the ice absorbs heat from the hand as well as from the surroundings . As a result of this loss of heat from the hand, the hand feels cold after. The process of this heat transfer is by conduction whereby heat is conducted away from the hand in order to melt the ice which is contact with the hand.

bicycle tyres become flat when the weather is cold.Why?
Answer:
The tires lose air pressure in the winter because it contracts. If you have 35 lbs in the summer, with 85 degrees, when it gets cold, down to -10, your air pressure can get down to about 25 lbs. So before it gets bitter cold, inflate your tires up a little. You don’t want to be putting air in your tires once it is freezing out. Sometimes the schrader valve doesn’t seat properly because of frost and the rubber seal is hard. I have had several tires go flat on me because of this.

Give 4 ""combining evidence"" in favor of organic evolution.
Answer:
1. Fossil record
2. Comparative anatomy
3. Embryology
4. Biogeography
Explanation:
Evolution is descent with modification. The organic evolution theory states that present complex life forms have evolved from the earlier (simpler) forms of life over time. Some of the most important pieces of evidence in support of the theory of organic evolution are:
1. Fossil record: fossils are dead remains of past living organisms preserved in the rocks of the remote past. These fossils demonstrate the existence of past living organisms that are related to present-day organisms.
2. Comparative anatomy refers to the study of similarities in the anatomy of different species, which provides direct evidence for identifying common ancestry between related species.
3. Embryology: the more recent the ancestor is that two species share, the greatest similarities in embryo structures and the more closely related the species are. In this regard, it is important to highlight that often homologous organs/structures (i.e., organs/structures descended from a common ancestor) can be observed only in embryos.
4. Biogeography refers to the spatial distribution of organisms and species. Species distribution reflects the evolutionary process when it is combined with geological change. For example, taxa that had already appeared before the separation of the continents are often distributed worldwide.

In this Food Web Pyramid Which type of consumer gets only 10% of the energy stored in plants?
A. Herbivore
B. Carnivore
C. Omnivore
D. Secondary Consume
Answer:
Herbivore, of course, I'm really sure that we all know exactly what a herbivore is, but as a refresher, a herbivore is like a vegetarian, they have a diet strictly based on plants. Carnivore's eat meat, not vegies, and an omnivore eats both, most humans are labeled as omnivores, except vegetarians. So your answer is Secondary Consume. This is because they only receive 10% in vegies, Primary Consume get 90%, Herbivores are Primary Consume's.
