Answer:
Plants absorb essential nutrients from the soil, hence they lack excretory organs. Particulate matter is not taken as these lack mouths.
Explanation:
Organisms like animals have an advanced and specialized system for excretion. But plants lack a well-developed excretory system like that in animals. They do not have special organs for excretion. Thus, excretion in plants is not so complex.

since the new strand made of short segments of RNA nucleotides, has a free 3'end what can attach and add nucleotides
DNA polymerase can attach and add nucleotides to the free 3' end of a new RNA strand made of short segments of RNA nucleotides during DNA replication.
RNA primase first adds a short RNA primer to the 3' end of the template strand, which serves as a starting point for DNA polymerase to attach and add nucleotides in a 5' to 3' direction. DNA polymerase can only add nucleotides to the free 3' end of the RNA primer or an existing DNA strand. Once the RNA primer is replaced with DNA nucleotides, the lagging strand can be joined to the leading strand through DNA ligase.
This process of DNA replication is semi-conservative, meaning that each new double-stranded DNA molecule is composed of one parent strand and one new daughter strand. This mechanism of DNA replication ensures the accurate transfer of genetic information from parent to daughter cells during cell division.

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.

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.

Why does a frameshift mutation usually cause more defects during protein
synthesis than a point mutation?
A. Frameshift mutations affect the whole chromosome.
B. Frameshift mutations only occur during translation.
C. Frameshift mutations can affect many amino acids.
D. Frameshift mutations are silent mutations.
Answer: C
Explanation: Because an insertion or deletion results in a frame-shift that changes the reading of subsequent codons and, therefore, alters the entire amino acid sequence that follows the mutation, insertions and deletions are usually more harmful than a substitution in which only a single amino acid is altered.
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.

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.

Maintaining a balance between the populations of kelp, otters, and urchins is important for the health and sustainability of the kelp forest ecosystem.
What is the carrying capacity of the kelp forest ecosystem?In a kelp forest ecosystem, kelp, otters, and urchins have a complex relationship. Kelp is the primary producer in the ecosystem and provides habitat and food for many organisms.
Otters are the primary predator of sea urchins, which are herbivores that feed on kelp. When otters are present in the ecosystem, they control the urchin population, allowing kelp to thrive. However, when otter populations decline, the urchin population can increase and overgraze the kelp, leading to a decrease in kelp abundance.

During photosynthesis, pigment molecules in chloroplasts must absorb eight photons (four by each photosystem) for every O2 molecule they produce, according to the equation 2H2O+NADP++8photons⟶2NADPH+2H++O2 The standard free‑energy change ( Δ′° ) for the light‑independent production of O2 is 400 kJ/mol. Assuming that these photons have a wavelength of 700 nm (red) and that the light absorption and use of light energy are 100% efficient, calculate the standard free‑energy change for the process.
The standard free-energy change for the photosynthesis reaction is -184 kJ/mol.
Since the reaction involves the production of O₂ and NADPH, we can write the equilibrium constant (K) as:
K = [NADPH]² × [O₂] ÷ [H2O]² × [NADP⁺]
Given that Δ′° = -400 kJ/mol, we can calculate the value of K using the relation:
ΔG° = -RT ln(K)
ΔG° = -400 kJ/mol
Assuming the temperature to be 25°C (298 K), and the gas constant R to be 8.314 J/mol K, we get:
ln(K) = ΔG° ÷ (-RT)
ln(K) = 400,000 J/mol ÷ (-8.314 J/mol K × 298 K)
ln(K) = -51.2
[tex]K = e^{-51.2}[/tex]
K = 3.3 x 10⁻²³
Now, we need to calculate the energy (E) of each photon using the relation:
E = hc ÷ λ
where h is Planck's constant, c is the speed of light, and λ is the wavelength of the photons.
E = (6.626 x 10⁻³⁴ J s x 2.998 x 10⁸ m/s) ÷ (700 x 10⁻⁹ m)
E = 2.84 x 10⁻¹⁹ J
Since 8 photons are required to produce one O₂ molecule, the energy required to produce one O₂ molecule is:
8 x 2.84 x 10⁻¹⁹ J = 2.27 x 10⁻¹⁸ J
To calculate the free-energy change (ΔG) for the process of photosynthesis using the relation:
ΔG = -nFE, where n is the number of electrons transferred, F is Faraday's constant, and E is the potential difference.
In this case, two electrons are transferred to produce one O₂ molecule and two NADPH molecules, and the potential difference (E) is 0.95 V
ΔG = -2 x (96,485 C/mol) x (0.95 J/C)
ΔG = -184,000 J/mol
ΔG = -184 kJ/mol

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.
