Answers
Answer:
Explanation:
Mesozoic Era, second of Earth’s three major geologic eras of Phanerozoic time. Its name is derived from the Greek term for “middle life.” The Mesozoic Era began 252.2 million years ago, following the conclusion of the Paleozoic Era, and ended 66 million years ago, at the dawn of the Cenozoic Era. (See the geologic time scale.) The major divisions of the Mesozoic Era are, from oldest to youngest, the Triassic Period, the Jurassic Period, and the Cretaceous Period. The ancestors of major plant and animal groups that exist today first appeared during the Mesozoic, but this era is best known as the time of the dinosaurs.

A genetics student is studying a plant that seems to have two Mendelian traits, flower color (red is dominant, and yellow is recessive) and seed color (brown is dominant, and green is recessive).
Use the Table button to create a Punnet square. Your Punnet square should show the possible offspring from one parent that is homologous recessive for both traits and the other parent that is heterogeneous for both traits. For flower color, use F and f, and for seed color, use S and s.
Then, based on the Punnet square you made, answer this question: What are the chances that the offspring will have the red flower, green seed phenotype? Show your work.

Answer:
Here is the plato answer !!!
FS fs Fs fS

According to the Punnett square, 4/16 plants will have red flowers and green seeds.
So, (4 ÷16) × 100 = 25% chance of obtaining offspring with red flower and green seed.

Mountain chains in northern Europe and West Africa match the Appalachian Mountains in terms of their ages and the sequences of rock layers that make them up. in 3-5 sentences analyze these observations and explain what conclusions can be drawn from them.
Answers
The above observation shows that the mountain chains in Northern Europe and West Africa are part of the Appalachian Mountains as a result of the same age, matching of rocks, etc
A mountain chain simply means a row of high mountain summits or a contiguous ridge of mountains within a larger mountain range.
The theory of plate tectonics establishes a co-relation with these mountain chains by understanding their movements. It was shown that Europe and Africa were part of the same landmass in the past. Due to the gradual movement of plates, both continents move apart.

Answers
Genetic codes are sets of three nucleotides that specify an amino acid. The three-nucleotide base read in the group is known as a codon.
What is a codon?A codon is a set of three nucleotides that codes for the genetic code of the deoxyribonucleic or the ribonucleic acid. The information in it is translated into proteins.
A codon also codes for the stop and start signal of the translation sequence. Each codon codes for particular amino acids and results in the formation of the proteins for cellular function and activity.
Therefore, the genetic code in a set of three is called a codon.

C o all new cells come from preexisting cells
do all living things are made of one or more cells
Answers
Answer:
A (if it is a multi-answer question) also B. Even also C.
Explanation:
C is definitely not the correct answer because germs and microbes are living things and are made of only 1 cell. The cell is also the smallest unit of life because it is called "the building blocks of life", so it has to be the smallest unit of life. Even C, because cells multiply using an existing cell, just like we humans reproduce. First, it duplicates all of its parts, or contents, including the DNA, then they split to create a new cell, (or if i'm incorrect, 2).

What is the metabolic process that breaks down organic molecules to release energy to be used by cells?
A. cellular respiration
B. light dependent cycle
C. light independent cycle
D. photosynthesis
Answers
Cellular respiration in living tissues is reduced at low temperatures. The amount of kinetic energy needed for chemical reactions like cellular respiration to occur decreases as temperature rises. Thus, option A is correct.
What importance of cellular respiration in an organism?As oxygen tension dropped, so did breathing rate, which eventually reached nil at low oxygen tensions.
Cell density had no bearing on this outcome. We provide a model to explain the observed impact of oxygen tension on cellular oxygen uptake.
As a result, increased cellular respiration is often associated with warmer temperatures.
Carbon dioxide concentration: The rate of respiration is inversely correlated with carbon dioxide concentration.
Increased carbon dioxide levels and a lack of oxygen have a negative impact on aerobic respiration rate.
Therefore, cellular respiration is the metabolic process that breaks down organic molecules to release energy to be used by cells.
