Answer:
Circadian rhythms.
Explanation:
Stimulus in biology can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). All living organisms (both plants and animals) respond to changes in their environment and as such an appropriate reaction or response is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.
In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ.
Since both plants and animals respond to environmental stimuli, it simply means that, these living organisms have physiological cycles referred to as circadian rhythms.
Circadian rhythms is a natural internal process that controls the physical, mental, and behavioral changes in living organisms such as the sleep-wake cycle. The circadian rhythm is simply the internal body "24 hour" clock.
For example, there are large changes in the activities that happens with respect to the organs such as kidney, liver and endocrine glands within the body of living organisms throughout the day. Also, they experience timely shift in blood pressure, amino acid levels, body temperature, metabolism, etc.
Hence, living organisms are usually more energetic and at alert when the aforementioned activities and others are at their highest point once a day as a result of circadian rhythms.

Animals are less likely to eat the plant and It tastes bad so they wont want to eat it again.
What are Adaptation?The process by which organisms adapt to their environment in order to increase their chances of surviving in that environment is known as evolutionary adaptation, or simply adaptation.
The biological process through which organisms adapt to brand-new surroundings or alterations in their current environments is known as adaptation.
Wallace and Darwin both went beyond basic adaptation when formulating the notion of evolution by natural selection by describing how organisms adapt and evolve.
Therefore, Animals are less likely to eat the plant and It tastes bad so they wont want to eat it again.

Why does temperature decrease with higher altitude?
A.
Air is held strongly together by gravity, so there is less heat transfer.
B.
Air density is lower, so there is less heat transfer.
C.
Air density is higher, so there is less heat transfer.
D.
Air pressure is higher, so there is less heat transfer.
Answer:
air density is lower, so there is less heat transfer
Explanation:
Radiation is absorbed by the ground of Earth and this heats the surroundings along with tropospheric air through conduction and convection process. ... Thus, we can conclude that temperature decrease with higher altitude as air density is lower, so there is less heat transfer.
Answer:
The correct answer would be B.
Air density is lower, so there is less heat transfer.

why animals need to move quickly
Answer:
Animals move for a variety of reasons, such as to find food, a mate, a suitable microhabitat, or to escape predators. For many animals, the ability to move is essential for survival and, as a result, natural selection has shaped the locomotion methods and mechanisms used by moving organisms.

Which description accurately describes the cell membrane?
a. a single permeable layer of phospholipids that have hydrophobic heads and hydrophilic tails
b. a semi-permeable double layer of phospholipids that have hydrophilic heads and hydrophobic tails
c. a single permeable layer of phospholipids that have hydrophilic heads and hydrophobic tails
d. a semi-permeable double layer of phospholipids that have hydrophobic heads and hydrophilic tails
e. a barrier of polypeptides that prevents molecules from entering or leaving the cell
Answer:
b. a semi-permeable double layer of phospholipids that have hydrophilic heads and hydrophobic tails
Explanation:
B is correct as the cell membrane is selectively semi-permeable. It is selectively semi-permeable because this quality allows it to control what can and can't enter the cell, and how it does so.
The cell membrane also has a phospholipid bi-layer comprised of a double layer of phospholipids which have hydrophilic head and hydrophobic tails. This is because the heads are made of phosphate and are polar and are therefore attracted to water (hydrophilic), while the tails are made of lipids (i.e. fats, oils) which do not mix with water and are therefore hydrophobic.
The properties of each phospholipid is also why they form the double layer structure, the hydrophilic heads naturally face outwards into the water and protect the hydrophobic tails on the inside.

How does the body structure evolve for animals as they transmit between the two environments?
Answer:
Biologists believe that new species evolve from existing species by a process called natural selection. ... Organisms that inherit that favorable new gene are likely to become more abundant than others of the species.

In a study published in the journal Nature, scientists studied eight ponds in Florida: four that were populated by a species of fish and four that were not. As they studied the ponds, they noted that the areas around the four fish-populated ponds showed decreased populations of dragonflies and dragonfly larvae, whereas the four without fish showed abnormally large populations of dragonflies and larvae. Dragonflies feed on bees, butterflies, and other pollinators.
Required:
Predict what would happen to the rate of pollination of flowers in a field next to a pond with no tish.
Answer: the rate of pollination of flower, in a field next to a pond with no fish, will DECREASE.
Explanation:
POLLINATION is defined as the process by which flowering plants, through the aid of external agents such as insects,wind, water and other animals, are able to transfer pollen grains from an anther to a receptive stigma. Insects are the most common pollinators. They visit flowers to obtain nectar and pollen as source of food. Flowers use various features, such as colour and scent, to attract and guide insects to the food source within them. In the process of reaching their source of food, insects bring about pollination.
From the study conducted by scientist in Florida, eight(8) ponds where subjected to the the study. The first four (4) ponds had species of fishes that fed on dragonflies and dragonfly larvae, hence the reason for a decrease in the population of the dragon flies in the area around it. While the remaining four (4) ponds had NO fish and the area around it is populated with dragonflies and dragonfly larvae. This is so because of the absence of fish.
It was then noted that the dragon lies fed of the insect pollinators such as the bees and butterflies. Since these dragonflies and its larvae are abundant in the field which is close to the pond with no fish, they will grossly depend on the insect pollinators as their source of food thereby decreasing the rate of pollination in the field next to the pond with no fish.

Suppose the stereocilia of one hair cell become permanently bent toward the kinocilium. What will most likely happen as a consequence
Answer:The options are not given, here are the options from another website.
a. A single pitch will be constantly perceived
B. A single pitch will no longer be perceivable
c. A or B depending on the hair cell's location
d. A or B depending on the bending's direction.
The correct option is d.
A or B depending on the bending's direction
Explanation:
This is because stereocilia are normal bent where there is a shearing force that occur when there is a up and down movements of the basilar membrane . When stereocilia bend towards the kinocilium, it make it depolarizes the cell and lead to the afferent activity to rise up and when the stereocilia bend away from the kinocilium , it hyperpolarizes the cell and lead to a reduction in afferent activity.
The consequences of this are that a single pitch will be noticed, or no pitch will be noticed. This will depend on the direction the stereocilia have bent.
We can come to this answer because:
Stereocilia are cellular accessories that help cells move around.They can curve up or down, generating different but very important effects.If the curvature is made towards the kinocilium, we can notice the formation of a pitch, as the cell becomes polarized.If the curvature is in the opposite direction to the kinocilium, the cell will be depolarized and it will not be possible to visualize the pitch.In this case, we can state that the consequences of the curvature of the stereocilia will depend on the side towards which this curvature is directed.

Part C Firefly luciferase is the enzyme that allows fireflies to illuminate their abdomens. Because this light generation is an ATP-requiring reaction, firefly luciferase can be used to test for the presence of ATP. In this way, luciferase can test for the presence of life. The coupled reactions are 1.2.luciferin+O2ATP⇌⇌oxyluciferin+lightAMP+PPiΔG∘=−31.6 kJ/mol If the overall ΔG∘ of the coupled reaction is -4.80 kJ/mol , what is the equilibrium constant, K, of the first reaction at 6 ∘C ?
Answer:
K = 9.620 × 10⁻⁶
Explanation:
From the given information:
Temperature T= 6° C
= (273 + 6)K
= 279 K
The correct and well presentation of the reactions are:
1. [tex]Luciferin + O_2[/tex] ⇆ oxyluciferin + light ΔG₁°
2. ATP ⇄ AMP + PP[tex]_i[/tex] ΔG₂° = -31.6 kJ/mol
The overall ΔG° = -4.80 kJ/mol
Let's first determine the ΔG₁° for the equation (1)
ΔG° = ΔG₁° + ΔG₂°
- ΔG₁° = - ΔG° + ΔG₂°
ΔG₁° = ΔG° - ΔG₂°
ΔG₁° = ( -4.80 - (-31.6) ) kJ/mol
ΔG₁° = 26.8 kJ/mol
Using the formula:
ΔG° = -RTIn K
[tex]In \ K =\dfrac{-\Delta G^0}{RT} \\ \\ log \ K = -\dfrac{\Delta G^0}{2.303RT}[/tex]
[tex]log \ K = -\dfrac{\Delta G_1^0}{2.303RT} \\ \\ log \ K = -\dfrac{26.8 \times 10^3 \ J/mol}{2.303\times 8.314 \ J/mol/K \times 279 \ K} \\ \\ log \ K =- 5.017[/tex]
K = antilog (-5.017)
K = 9.620 × 10⁻⁶

This paramecium has a nucleus and is comprised of one cell. Which terms best describe this organism?
Answer: The term that best describes this organism is that it's a UNICELLULAR PROTISTA.
Explanation:
Unicellular organisms are that are made up of just one cell. They are also called single- celled organisms. Examples of unicellular organisms include: Amoeba, chlamydomonas and paramecium.
The paramecium is a protist which is SINGLE-CELLED and is made up of eucaryotic cells in which the cell structure is complex with a well-defined NUCLEUS.
The structure of this organism helps it to survive in its environment. It has cilia that helps it move food into its gullet.
The food vacuole circulate along a definite path in the cytoplasm. The anterior and posterior contractile vacuole, with radiating channels draining into them, helps to get rid of excess water from the body. The food vacuoles circulate along a definite path in the cytoplasm. The anterior and posterior contractile vacuole, with radiating channels draining into them, helps to get rid of excess water from the body.
The NUCLEUS is used by the organism for sexual reproduction. This occurs in a process known as conjugation whereby the whole organism pair with another similar whole organism and exchange their nuclei.
