Mendel drew several key conclusions based on his observations of pea
plants. Which of the following best describes one of his conclusions?
A. A parent can pass on only one factor for each trait to its offspring.
B. An offspring that inherits different versions of the factor for a trait
will not survive.
C. Hereditary factors blend together to produce the traits of
offspring
D. Dominant hereditary factors are those that help an individual
survive and reproduce.
The best statement that describes the conclusion of the given scenario, is that parent can pass on only one factor for each trait to its offspring. The correct option is A.
What is Mendel law?Gregor Mendel proposed the law of inheritance after seven years of research on pea plants.
Mendel's inheritance laws encompass the laws of dominance, segregation, and independent assortment.
In this, the parent can pass on only one factor for each trait to its future offspring.
Thus, the correct option is A.

plants and algae. These organisms are called primary consumers or herbivores. Some examples are rabbits, deer, tadpoles, and caterpillars. organisms are called secondary consumers.
Answer:
Herbivores
Explanation:
A rabbit is very close to the bottom and they are ‘consumers’. They are herbivores, meaning that they mainly eat plant matter. They are also prey animals so larger animals capture and eat them.
Which statement best explains why herbivores are not considered parasites
Answer:
Hello There!!
Explanation:
The answer is=>Parasite means that the organism must live inside (intracellular) or on the outside body of the organism (extracellular). The herbivores do not live on the host (plants) for its survival. They just eat the plants and fruits for getting energy. Therefore, the herbivores cannot be called as parasite.

Take a look at the two boxes below. Each box has the same volume. If each ball has the same mass, which box 1 or 2 would weigh more? Why?
Answer:
Box 1.
Explanation:
The box 1 have the more mass because there are large number of balls present in the box while on the other hand, box 2 has less number of balls in the box. The volume of box boxes are the same as well as weight of the both boxes before placing of balls. Placing of balls changes the weight of both boxes because of the presence of different number of balls in each boxes.

the darker (blue / dark blue) areas are colder, do we expect less dense mattet/stars
since the areas are overall equal in energy density (note that the different color represent very little difference in temperature), we can expect a common origin, because regions of space so vastly apart couldn't possibly smooth out later, they would be to far apart.

D) At what rate is the sea level expected to rise in the next 100 years?
E) Which coastal towns face the greatest risk of flooding because of the rising sea level?
Above are the questions about the present data that would help coastal communities plan for a natural disaster now and in the future in order to prevent floods and other natural disasters. The main reason for this rising of sea level is the release of huge amount carbondioxide gas in the atmosphere that causes global warming which leads to melting of glaciers and the sea level rises.

Which of the following is TRUE about the movement of earth's plates?
A. They do not move because they sit on a layer of solid rock
B. They move along with the layer of slightly softened rock below them
C. They move by floating on a layer of completely melted rock below them
D. They do not move until the solid rock layer beneath them temporarily melts and moves
Answer:
c
Explanation:
the tectonic plates or the crust of the earth sit on molten rock moving across the planet with causes the plates to move causing things like earthquakes and volcanos
Movement of Earth's plate can be due to many reasons and can cause many disasters. They move along with the layer of slightly softened rock below them
What is the 3 causes of this movement?Earth's plates move due to the intense heat in the Earth's core. This causes the movement of soften rock in the mantle layer.
It moves in a convection cell pattern that forms by rising of warm, cooling and then sinking down of material.
The Earth's plates move by floating on a layer of completely melted rock below them.
Thus, the correct option is B.

The endosymbiosis hypothesis is supported by all of the following pieces of evidence except the fact that Group of answer choices chloroplasts reproduce through a splitting process like certain prokaryotes. mitochondria have circular DNA like prokaryotes. chloroplasts have ribosomes like prokaryotes. mitochondria lack ribosomes like prokaryotes.
Answer:
The correct answer is - mitochondria lack ribosomes like prokaryotes.
Explanation:
The Endosymbiotic Theory says that mitochondria and chloroplast in eukaryotic cells are developed by the once aerobic bacteria that were engulfed by a large anaerobic bacteria.
This theory suggests the origin of eukaryotic cells. Various evidence exists such as mitochondria and chloroplasts contain their own circular DNA like prokaryotic cells and mitochondria and chloroplasts have 70S ribosomes like prokaryotes have.
Four relatively recent fossil species were recovered, and when the DNA was extracted, investigators observed that Species W and Z both had long finger bones, and species X and Y had short finger bones. Based upon this information and the hypothetical molecular data below, sequenced from common regions in one gene of their DNA, which two species are the most closely related to each other?
Species W:
AACATTGCTT
TTGTAACGAA
Species X:
AACCGCGCGT
TTGGCGCGCA
Species Y:
AGCAGCGCTT
TCGTCGCGAA
Species Z:
AACCGCGCTT
TTGGCGCGAA
A) Species X and Z
B) Species W and Z
C) Species Y and Z
D) Species X and Y
Answer:
A) Species X and Z
Explanation:
When comparing DNI sequences, you can see that the individuals with the most similar chains are X and Z. They only differ in the penultimate pair of bases. Species X carries guanine-cytosine pair, while species Z carries the Timin-Adenine pair.
Species X: Species Z:
AACCGCGCGT AACCGCGCTT
TTGGCGCGCA TTGGCGCGAA
The other species differ a lot from each other.
