What structure do fish lose that other vertebrates keep?
Aquatic vertebrates such as fish have developed special adaptations to live in water. Loss of a bone component in their ears known as the "labyrinthine apparatus" is one of these adaptations.
All other vertebrates have this structure, which serves as a sound wave detector and aids in balance and orientation. However, in fish, a more straightforward system of canals filled with fluid and sensory cells has taken the place of this structure.
It is believed that fish evolved without the labyrinthine apparatus to lighten the weight of their heads and increase swimming efficiency.
Fish have evolved various adaptations, such as specialised sense organs and lateral lines, to navigate and live in their aquatic environment despite the absence of this structure.

Answer:
Osmosis
Explanation:
water is drawn into the root hair cell by osmosis.The cell sap is usually more concentrated than the soil water.A concentration gradient exists between the cell sap in the vacuole of the root hair cell and the soil water.This exerts a higher osmotic pressure that leads to drawing of water molecules into the root hair cell by osmosis then finally to the xylem vessels.

Since HG = MP and GK = PN, triangles H G K and M P N are congruent by the Side-Side-Side (SSS) congruence criterion.
Therefore, the corresponding angles and sides of the two triangles are equal. In particular, we have:
Angle H is congruent to angle M (corresponding angles).

What is the result of the cross?Alleles are different gene forms that share the same location on a chromosome and regulate the same trait. An individual can have two alleles (one from each parent) for each gene, and they can be dominant or recessive.
This cross would not produce any white short-eared sheep. Either the long-eared offspring would be white or the short-eared offspring would be black. The cross shows that about 100 of the white short-eared sheep would be produced.

Find every angle of rotation that maps the figure onto itself.
Answer: Assuming the rectangle is not a square, a rotation of 180º, -180º, 360º, -360º will rotate the rectangle back onto itself.
If you want to consider angles beyond 360º, any rotation of k(180º) where k is an integer will work.
If you are looking at that special case of rectangle known as a square, any rotation of k(90º), where k is an integer will do the trick.

what is the basic concept behind relative age dating of fossils a the Upper Rock layers were deposited earlier in the Lower Rock layers b the Lower Rock layers were deposited earlier than the Upper Rock layers c the older fossils contain relatively higher levels of radioactive d the younger fossils contain relatively higher levels of radioactive isotopes in the older fossils
The basic concept behind relative age dating of fossils is that the Lower Rock layers were deposited earlier than the Upper Rock layers. This is because the principle of superposition states that in an undisturbed sequence of sedimentary rocks, the oldest rocks are at the bottom, and the youngest rocks are at the top. As a result, fossils found in the lower layers are generally older than those found in the upper layers. This method of dating does not rely on measuring radioactive isotopes or other methods that require absolute dates, but rather on the relative position of the fossils within the layers of rock.

What information can a scientist learn directly from a single fossil?
A. How many offspring the organism produced
B. The organism's shape and size
C. How the organism is related to others
D. The life expectancy of similar organisms
Answer:
B. The organism's shape and size.
Explanation:
A single fossil can provide information about the shape and size of the organism that it belonged to. Fossils can also provide information about the age of the rock layer in which they were found. However, it is usually difficult to determine other characteristics such as how many offspring the organism produced, its relationships to other organisms, or the life expectancy of similar organisms from a single fossil. These types of information often require the study of multiple fossils or the use of other scientific methods.

Effect on humans:
Origin; Silt suspended in the water surrounding a coral reef near the coast of a small island community in the Caribbean Sea, Effect on one organism; Silt suspended in the water can have negative effects on the coral reef ecosystem. and Effect on humans; The silt suspended in the water can also have negative effects on humans.
Effect on one organism; Silt suspended in the water can have negative effects on the coral reef ecosystem. Silt can reduce the amount of light available to the coral and other photosynthetic organisms, hindering their ability to produce energy through photosynthesis. Additionally, silt can clog the coral's feeding and respiratory structures, causing them to starve or suffocate.
Effect on humans; The silt suspended in the water can also have negative effects on humans. Silt can reduce the water quality, making it cloudy and turbid, and reducing visibility for swimmers, divers, and snorkelers. Silt can also smother and kill seagrasses and other plants, which provide important habitat and food for fish and other marine animals, potentially reducing the amount of seafood available for human consumption.

on lagging strand when DNA polymerase reaches the next okazaki fragment it detaches and moves to the next section of DNA that is primed it continue moving in a 3' to 5' direction and repeats this pattern of detaching and moving to a newly primed section of DNA
The given statement " on lagging strand when DNA polymerase reaches the next okazaki fragment it detaches and moves to the next section of DNA that is primed it continue moving in a 3' to 5' direction and repeats this pattern of detaching and moving to a newly primed section of DNA" is false.
DNA polymerase does not move in a 3' to 5' direction during replication, rather it moves in a 5' to 3' direction. On the lagging strand, DNA polymerase synthesizes short discontinuous fragments called Okazaki fragments in a 5' to 3' direction away from the replication fork. When DNA polymerase reaches the end of one Okazaki fragment and encounters the beginning of the next, it does not detach from the DNA strand, rather it remains bound to the template strand and continues extending the new fragment in a 5' to 3' direction towards the replication fork.
On the leading strand, DNA polymerase moves continuously in a 5' to 3' direction towards the replication fork, without detaching from the template strand. The process of DNA replication involves complex enzymatic reactions, and it is important to understand the correct directionality and mechanisms involved to accurately explain the process.

1.11 Graded Assignment: Discussion: Differentiating Among Newton's First, Second, and Third Laws
So you have to write what are the differences between newtons 3 laws and what they are
1. Newton's first law of motion projects that a object at rest will remain at rest, and a object in motion will remain in motion with a constant velocity, until or unless a force is acted upon by the external environment.
2. Newton's second law of motion projects that the acceleration of an object is considered to be directly proportional to the net force acting on the object and generally inversely proportional to its mass.
3. Newton's third law of motion projects that for every action, there is an equal and opposite reaction.
The first law is also renowned as the law of inertia. The second law thoroughly distinguishes the relationship between applied force and the rate of change of momentum. And finally the third law is also know as the law of action and reaction because it depends on the type of stimulus that is experienced from the environment when the individual is applying force.
