Malthus, who thought that populations could outgrow their food sources was the scientist who most inspired Darwin to pursue his studies of evolution.
What do you mean by Evolution?Evolution may be defined as a procedure of gradual transformation that takes place over many generations, during which species of animals, plants, or insects slowly modify some of their physical characteristics.
Malthus was not only a scientist but an economist who understood the poulation growth. This idea of Malthus fascinated Darwin to work on evolution and its processes.
Therefore, the correct option for this question is B.

Why is knowing information about embryo development important?
Answer:
It helps you understand how life forms and what it takes for life to develop as well as the changes through this life cycle
Explanation:
Knowing information about embryo development is important because it helps us to understand how an organism grows and develops from a single cell into a complex being.
Why knowledge about embryo development important?An embryo is the stage of development that follows fertilization and begins when the zygote, a single cell formed by the union of a sperm and egg, begins to divide and differentiate into the various cell types that will make up the organism.
This knowledge can be used in various fields, such as reproductive medicine, to help improve fertility treatments and increase the chances of successful pregnancies. It can also be used in fields such as genetics and evolutionary biology to understand how traits are inherited and how species have evolved over time. Understanding embryo development can also provide insights into the causes of birth defects and developmental disorders, and help researchers develop treatments or interventions to improve the health and well-being of individuals.

Explanation: We know for certain the son is NOT ww because the son has the dominant trait for the widow's peak. Both the parents are Ww because their daughter lacks a widow's peak, which means they both must carry the recessive gene. If we conduct a Punnett Square with the parents genotypes which are both Ww, the son has a 25% chance to be WW, and a 50% to be Ww and a 25% chance to be ww (which he is not since he has a widow peak!). The son could be WW or Ww. In order to find out which genotype the son has, we'd have to look as his offspring!

In your own words, explain why an organism would require all four of the main biomolecules. What would occur if any of these biomolecules were missing? Are any of the biomolecules more important than the others? Is there one that we could live without?
Answer:
An organism requires all four main biomolecules because each provides a specific and necessary function for the organism. None of the biomolecules is more important than another, and if any of them were missing, life would not be possible.
Explanation:
The main biomolecules of living beings are carbohydrates, proteins, lipids and nucleic acids, each with a specific function and necessary for the development of life.
The presence of these four biomolecules is necessary because each one fulfills specific and irreplaceable functions, such as:
Carbohydrates: are the main source of energy, forming part of organic biomolecules such as glycolipids, glycoproteins or sugars that form the structure of nucleic acids.Proteins: important for their structural function and for molecules such as enzymes, which contribute to organic functions. They are also part of the cell membranes.Lipids: are the molecules that predominantly form the cell membranes. Additionally, they form functional molecules, such as hormones, and are a reserve energy source.Nucleic acids: DNA and RNA are not only necessary for organic biosynthesis, but also determine the structure and function of each organism. The reproductive and perpetuation function of the species is based on the transfer of genetic material contained in the DNA to the offspring.What would occur if any of these biomolecules were missing?If one of the main biomolecules were missing, the function it provides could not be supplied by another, which would imply the non-viability of a living being. If carbohydrates are missing there is no source of energy, without proteins there would be no tissues like muscle and no enzymes to facilitate organic reactions and without lipids there would be no cells. The absence of nucleic acids, per se, would determine the impossibility of all organic processes.
Are any of the biomolecules more important than the others?No one biomolecule is more important than another. Each one of them fulfills a specific and necessary function that cannot be supplied by another biomolecule.
Is there one that we could live without?All organic molecules are necessary, fulfilling an important function. The lack of any biomolecule in the organism is incompatible with life.
An organism requires all four of the main biomolecules because they're all important for the effective functioning of the organism.
It should be noted that the main biomolecules include protein, lipid, carbohydrates, and nucleic acids. They all play a vital role in how an organism functions.
If any of these biomolecules were missing, the function that can be provided by the biomolecule can't be provided by another biomolecule since they all play different roles. Also, there's no biomolecule that's important than another.

Select statements true of fracture zones.
Select statements true of fracture zones. Choose one or more:
A. Earthquakes can occur along fracture zones.
B. Fracture zones are situated perpendicular to mid-ocean ridge segments. C. New crust is formed via seafloor spreading along fracture zones.
D. Fracture zones can act as transform boundaries between two actively spreading ridge segments.
Fracture zones are situated perpendicular to mid-ocean ridge segments.
What are fracture zones?Fracture zones are a consequence of plate tectonics, they are an oceanic feature that is linear and sometimes travels thousands of kilometers due to the action of displaced mid-oceanic ridge axis segments. These zones are seismically inactive since the two fracture zones move in the same direction.
These fracture zones are important since by studying them it is possible to determine the direction and speed that their movements can have.
Therefore, we can confirm that fracture zones are situated perpendicular to mid-ocean ridge segments.

Earth Science: Q14. Explain the principles of the plate tectonics theory.
Answer: Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core. The plates act like a hard and rigid shell compared to Earth's mantle. The key principle of plate tectonics is that the lithosphere exists as separate and distinct tectonic plates, which float on the fluid-like (visco-elastic solid) asthenosphere. The relative fluidity of the asthenosphere allows the tectonic plates to undergo motion in different directions.

Which arrow represents the centripetal force responsible for this motion?
W
X
Y
Z
Answer:
The Answer is Y
Explanation:
Y is the arrow pointing towards the center of the circle and the centripetal force always goes toward the center of the circle.
The arrow that represents the centripetal force responsible for this motion is : Arrow Y
Direction of arrow YArrow Y points towards the center of the circle which is the same direction as the centripetal force acting on body whcih follows a curved path. centripetal force moves to the center of the circle ( i.e circular path ) of the object.
