Most of the mass in the solar system is contained in
(A) the Sun
(B) Jupiter
(c) the inner planets
(d) the outer planets
Answers
Answer:
A} the sun
Explanation:
The sun is the greatest and heavier then the other planet
Most of the mass in the solar system is contained in the Sun. Option A is correct.
The majority of the solar system’s mass lies between 99.8% and 99.9% in the Sun. The remainder is distributed among the planets, their satellites, comets, asteroids, and the surrounding interstellar dust and gas.
The solar system's gravitational field is dominated by the sun, which makes up 99.85%. The planets, condensed from the same disc of matter that created the sun, make up 0.135%.
The sun is located at the center of the solar system and is the largest object in the Solar System by far. It is 109 times the size of the Earth. About one million Earths would fit inside the sun.
Therefore, the correct option is option A.

What is an event of a convention current in the air
Answers

how does geographic isolation cause an increase in differences between two groups
Answers
Answer:
What was once a continuous population is divided into two or more smaller populations. This can occur when rivers change course, mountains rise, continents drift, or organisms migrate. The geographic barrier isn't necessarily a physical barrier that separates two or more groups of organisms. It might just be unfavorable habitat between the two populations that keeps them from mating with one another.

Answers
Answer:
Magnitude
Explanation:
Magnitude is expressed in whole numbers and decimal fractions. For example, a magnitude 5.3 is a moderate earthquake, and a 6.3 is a strong earthquake. Because of the logarithmic basis of the scale, each whole number increase in magnitude represents a tenfold increase in measured amplitude as measured on a seismogram.
What is the function of each of these structures in the cell membrane? a) phospholipid bilayer b) peripheral protein c) integral protein d) glycolipid & glycoprotein e) cholesterol
Answers
Answer:
The correct answers are described in the Explanation section.
Explanation:
The function of the structures in the cell membrane are as follows:
a) phospholipid bilayer: comprised of fatty acids and alcohol, the phospholipid bilayer acts as a hydrophobic barrier to avoid the uncontrolled transport of molecules and ions.
b) peripheral protein: they are proteins present in the external surface of the cell membrane. This proteins form temporary bonds between the cells and other molecules, attaching and detaching at specific times.
c) integral protein: this proteins have one part of its structure in the surface and other part within the cell membrane. They have different roles, including: receptors, transporters, linkers, channels, among others.
d) glycolipid & glycoprotein: proteins that have carbohydrate-bearing portions in its extracellular environment. They maintain the stability of the cell membrane and facilitate cellular recognition.
e) cholesterol: cholesterol structure helps to the packing of the phospholipids, which restricts the passage of the molecules.

in the dihybrid cross for pea plants shown below, ris dominant for round peas, ris recessive for wrinkled peas, y is dominant for yellow peas, and y is recessive for green peas. a student could accurately make which statements about the offspring of this cross
A. There is a 50% chance of having round, yellow peas
B. There is no chance of having round, yellow peas
C. There is a 100% chance of having round, green peas
D. There is no chance of having any wrinkled, green peas
Answers
Answer:
D, there's no chance of having any wrinkled, green peas
In the given scenario, there is no chance of having any wrinkled, green peas. The correct option is D.
What is dominant and recessive characters?When a trait has two different forms at the gene level, dominant and recessive traits exist. The dominant trait is the trait that first appears or is visibly expressed in the organism.
The recessive trait is one that is present at the gene level but is masked and does not manifest itself in the organism.
A trait that is expressed only when the genotype is homozygous; a trait that is masked by other inherited traits but persists in a population among heterozygous genotypes.
Dominant inheritance refers to the inheritance of traits that are typically passed vertically from parent to child, with both the parent and the child affected by the trait or disorder associated with that gene.
In the given image, there is no recessive alleles, all are in combination with the dominant one, so it is not possible to have wrinkled, green peas.
Thus, the correct option is D.

Convergent evolution is a process where organisms independently evolve traits. Some molecular data place the giant panda in the bear family (Ursidae) but place the lesser panda in the raccoon family (Procyonidae). Consequently, the morphological similarities of these two species are probably due to
Answers
Answer:
analogous structures
Explanation:
Analogous structures play similar and/or identical functions in unrelated organisms. For example, moths and bats both have wings, even though they aren't related. Convergent evolution is a process that generates analogous structures in organisms that don't share a common ancestor with such structures. Moreover, homo-logous structures are shared traits between organisms that share a common ancestor. On the other hand, divergent evolution is a process associated with the accumulation of phenotypic differences between organisms within a species, which eventually lead to speciation.

Jonas and his family are moving to another part of the city. As Jonas, his brother, and his Dad were driving one of the trucks filled with furniture to their new home, Jonas noticed that the truck seemed to take longer to stop now that it was heavier with the furniture. Which Newton's Law explains why this happens?
Answers
Answer:
Newton's 2nd Law of Motion
Explanation:
A force applied to an object at rest causes it to accelerate in the direction of the force. It is easier for the empty truck to stop than a full truck, because the full truck has more mass than the empty one.
This phenomenon is explained by the law of inertia i.e. the first law of Newton.
What is Newtons's first law?According to Newton's first law, unless pushed to alter its motion and direction by the operation of an external force, every object will continue to be at rest or in uniform motion in a straight line. It is also known as the law of inertia.
A body's inertia is a quality that makes it resist changes to its state. The amount of a body's inertia in translational motion is determined by its mass. A heavier body's consistent motion or state of rest is challenging to alter, and the opposite is true for lighter bodies. This is why the truck filled with furniture takes longer to stop.
Thus, when Jonas noticed that the truck seemed to take longer to stop now that it was heavier with the furniture. It is explained by the first law of motion (law of inertia).
