A graph over time of salinity and conductivity at an upper estuary site will be less inclined than that at a lower estuary site.
What are salinity and conductivity measurements?Salinity is a measure of the salt content of a water body.
Conductivity is a measure of the electrical conductivity of a solution or substance.
Conductivity increases with increase in salinity.
An estuary is a region where salt water from the sea meet freshwater from a river or stream.
At an upper estuary site where farmers use the water for irrigation, there will be decreased salinity and conductivity with time, while at a lower estuary site where there is a bream and flathead fishing industry, their will be increased salinity and conductivity with time.
Therefore, a graph over time of salinity and conductivity at an upper estuary site will be less inclined than that at a lower estuary site.

Background: You will be the evolutionary biologist, and complete the following activities
to build a cladogram of Xenites. Based on the order of the rock layers in which fossils
were found, species A appears to be the oldest and probably the most primitive.
1. Fill in the table noting which species of xenite has each characteristic, marking each
yes or no. (3 points)
Observing each of the animals shown we have to classify what each one of them has that differs from the other in this way, the evolutionary process of each one is:
Xenite A: Have eyestalksXenite B: Have eyestalks and mouthXenite C: Have eyestalks, tail and mouthXenite D: Have spine and eyestalksXenite E: Have spine, eyestalks and mouth.What is evolutionary process?Evolutionary processes aim, therefore, to generate greater adaptation of species in an environment. This concept of adaptation is related to several other evolutionary processes, mainly speciation, when new species of organisms are formed from gradual changes in preexisting species.
In this case, the most evolved species to the most evolved is:

Economic importance of tilapia fish
Answer:
Tilapia is one of the most productive and internationally traded food fish in the world. The production of farmed tilapia is among the fastest expanding food sectors in the world. Nile tilapia ( Oreochromis niloticus) is the most cultured freshwater species among the farmed tilapia and contributes about 71% of the world total tilapia production.
Tilapia is one of the most important farmed fish species worldwide (FAO 2018) and an important source of protein (Fitzsimmons 2000;Hai 2015). Due to its sequenced genome (Conte et al. 2017), easy reproduction, efficiency in adapting to diverse diets, high resistance to diseases and handling practices, and high tolerance of a wide variety of husbandry conditions, it is considered an ideal model in toxicological research.

You are provided with three liquids - Water, honey and oil. On pouring the three liquids simultaneously without disturbing. What will be the arrangement of these liquids from top to bottom and why? Conduct this experiment at home and paste the picture of it with proper labeling
Answer:
Honey would be on the bottom, water in the middle, and oil on the top.
Explanation:
Honey is on the bottom because it has a is greater density than water, and oil is on the top because it has less density than water.
It all depends on the viscosity of the materials. Honey on the bottom, oil floating on top and in the middle is water.
What kind of liquids float on water ?The liquids which are in lesser weight just floats over the surface of water.
In the attached image it can be seen clearly that the denser of all is honey which has the property of viscosity as well and it just settles down on the surface whereas the lighter of all is the oil which is seen floating on the surface.
Oil and Water is usually the most common type of example of the two types of immiscible liquids. In this no matter what quantity you mix the oil and water in that they do not mix up . The reason why this happens is as of the basic chemical nature of the oil and the water molecules.

Why do plants contain the
greatest amount of energy in the
food pyramid?
Answer:
According to the pyramid of energy, the energy content is maximum in autotrophs or producers. Autotrophs are the plants which prepare their food by photosynthesis. They are the primary producers and primary source of food energy. The flow of energy is unidirectional from producer to consumer level.
Explanation:
According to the energy pyramid, autotrophs or producers have the highest energy content. Autotrophs are plants that prepare their nourishment through photosynthesis. They are the key producers and energy sources for food. Energy flows unidirectionally from producer to consumer.
What is an Energy pyramid?A trophic pyramid, also known as an ecological pyramid, is an illustration of the flow of nutrients through an ecosystem. It is a graphical representation of the proportions of energy available in an ecosystem at each trophic level, or feeding level.
The pyramid of energy is often divided into tiers, with primary producers, like power plants, at the bottom. Above the primary producers come the principal consumers, which include herbivores that eat plants. Then there are secondary consumers, like carnivores that eat herbivores, and so on.
Thus, according to the energy pyramid, autotrophs or producers have the highest energy content.

2. A technique that associates a natural response to a stimulus to an unrelated stimulus; also called Pavlovian conditioning -- classical conditioning
3. The study of animal behaviour in its natural environment - ethology
4. When an animal learns not to respond to a stimulus - habituation
5. Finding a solution to a once unsolvable problem - insightful learning
6. Learning that has taken place but is dormant until a situation requires it - latent learning
How, explain your answer?
Activational effects are the sudden or immediate temporary transient effects of behavioural changes due to the influence of hormones, especially the gonadal or these hormones. The behaviour change in male animals due to an increase in male se hormonal activity can be referred as an activational effect.
Classical conditioning facilitates learning of a behaviour when a conditioned stimulus is associated with an unconditioned stimulus leading to a conditioned response. Animal training by pairing a new unconditioned stimulus with an already known conditioned stimulus, a new conditioned response of behaviour change can be observed.
Ethology refers to the scientific zoological study (includes both laboratories as well as natural field studies) of animals' behavior with relation to their natural environment. It studies and compares about animal behavioral processes changes under various disciplines like ecology, anatomy, evolution etc.
Habituation is an associative learning process that results when an animal learns to resist a stimulus and not to respond to it after repeated exposure.
Insightful learning occurs when various parts of a problem are analyzed and their relationship is understood to arrive at the solution suddenly. Animals must look at a situation as a whole, and observe and analyze it to solve the problem. Some animals like chimpanzees can learn through insightful learning
Latent learning occurs without any associated reinforcements. Animals learn new behaviour through latent learning.

In DNA Replication, ATTTGC is complementary to TAAACG. True or False?
Answer:
True.
Explanation:
It's commonly known that adenine pairs with thymine and guanine pairs with cytosine following complementary base pairing.
The statement "In DNA Replication, ATTTGC is complementary to TAAACG" is definitely true.
What is DNA replication?DNA replication may be defined as the biological process through which two identical replicas of DNA are formed from one original DNA molecule. It occurs in all living organisms acting as the most essential part of biological inheritance.
The process of DNA replication is commonly known for some complementary sequences. For example, adenine pairs with thymine, and guanine pairs with cytosine which effectively follows the process of complementary base pairing.
This base pairing of nucleotides will follow Chargaff's rule which states that the amount of adenine is always equal to the amount of thymine, while the amount of guanine always equal to the amount of cytosine.
Therefore, the statement "In DNA Replication, ATTTGC is complementary to TAAACG" is definitely true.
