Explanation:
RNA polymerase moves in the part of the DNA that has been opened and forms a complement to one of the strands of DNA called RNA.
RNA is made because DNA is always in the nucleus,but ribosomes for making proteins are found in the _______
Answer:
Cytoplasm
Explanation:
In eukaryotes, there is a definite nucleus where the ribosome and mRNA production takes place. The ribosomes and mRNA come out of the nucleus into the cytoplasm where the ribosomes work upon and catalyze the formation of proteins. Meaning that in eukaryotic cell, ribosomes make proteins in the cytoplasm.
Explanation:
Ribosome existed in the rough endoplasmic reticulum and existed freely in cytoplasm

List all the gametes that are possible with each of the following genotypes.
a. Aabb
d. AABb
b. AaBB
e. AAbb
C. AaBb
f. aabb
All the possible gametes for Aabb would be Ab and ab; that of AABb would be Ab and AB; that of AaBB would be AB and aB; that of AAbb would be Ab; that of AaBb would be AB, Ab, aB, and ab; and that of aabb would be ab respectively.
Gametes formationThe formation of gametes for a dihybrid involves the crossing of the two traits involved.
Thus: Aabb is equivalent to crossing Aa and bb
Aa x bb
Ab Ab ab ab
Hence, all the gametes would be Ab or ab.
For AABb: AA x Bb = AB Ab AB Ab
The gametes are either AB or Ab
For AaBB: the gametes are either AB or aB
For AAbb, only Ab gametes are produced
For AaBb: the gametes would be AB Ab aB and ab
For aabb: only ab gametes are produced.

How does a noncompetitive inhibitor decrease the rate of an enzyme-catalyzed reaction?.
Describe the relationship between rocks and fossils found in the same rock layer.
Answer:
The three concepts are summarized in the general principle called the Law of Fossil Succession: The kinds of animals and plants found as fossils change through time. When we find the same kinds of fossils in rocks from different places, we know that the rocks are the same age. Scientists look for ancestors and descendants through geologic time.

What is the role of oxygen in photosynthesis and in cellular respiration?
A) Oxygen is used in photosynthesis to produce glucose and is released during cellular respiration
B) Oxygen is released in photosynthesis and used in cellular respiration to produce energy
C) Oxygen is combined with carbon dioxide in photosynthesis to release energy and released from carbon dioxide during cellular respiration
D) Oxygen is released from glucose during photosynthesis and combines with carbon dioxide to produce energy during cellular respiration
The main role of oxygen in photosynthesis and respiration is that Oxygen is released in photosynthesis and used in cellular respiration to produce energy.
Role of oxygen in photosynthesis and respirationIn photosynthesis, water and carbon dioxide reacts to form oxygen and glucose while on the other hand, In cellular respiration, oxygen is used to break down glucose in order to release energy in the form of ATP.
So we can conclude that the main role of oxygen in photosynthesis and respiration is that Oxygen is released in photosynthesis and used in cellular respiration to produce energy.

Refer to the diagram to answer the question. Which statement is true regarding how muscles contract?
Question 16 options:
Sarcomere A is contracted.
Sarcomere B is relaxed.
D represents Myosin.
C represents Myosin.
The figure is not found here, but myosin is the protein required for muscle contraction, whereas sarcomeres are functional units of muscles.
What is a sarcomere?A sarcomere can be considered as the functional unit of a muscle, which is a type of contracting tissue.
A sarcomere is a unit composed of thick myosin fiber filaments and thin actin protein filaments.
These protein filaments work together to contract and expand sarcomeres and thus produce muscle movement.

What are the gonads in the male reproductive system.
Both men and women have gonads. In males, they are the testes, or testicles, the male s#x glands that are part of the male reproductive system. They are located behind the p#nis in a pouch of skin called the scrotum. The female gonads, the ovaries, are a pair of reproductive glands.
A large population of turtles lives on Island A. During a major storm, half of these turtles are washed onto a neighboring Island B. Over millions of years, the two populations diverge, or grow differently, leading to natural selection on the two islands. The two populations of turtles from Island A and Island B are brought back together after another storm. What can be said about these turtles?
What that can be said about these turtles is that Even though they were geographically Isolated, they are no longer two species because they are living together again.
What is population?Population refer to total number of living organisms of species that interact with their environment and living in a same place at the same time.

Are heated air and wind shear the cause for severe storms? Explain.
Answer:
Yes, they are very much the main cause of severe storms because the heat molecules get into the atmosphere and clouds, causing chemical reactions and damage. At some point in time, the energy built up, as well as the damage done, must undo itself. This is done through a storm. It is the environment's way of cleaning itself.
As a part from this video below states, wind shear is a leading cause in severe storms.

Assume all of the presynaptic synapses identified produce epsps. If two of these synapses fired simultaneously, which synaptic combination brings the initial segment closest to threshold based on spatial summation?.
The synapses that are nearer to the axon hillock would bring the initial segment closest to the threshold based on spatial summation.
What is neuron synapsis?In neurosciences, the term synapsis makes reference to the connection between two nerve cells (neurons).
Synapsis is produced by the connection between axons and dendrites among different neurons.
Spatial summation refers to the start (trigger) of the action potential in neurons via two or more presynaptic cells.

What does fossil evidence show about evolution?
Answer:
Answer below
Explanation:
Fossils provide physical examples of what organisms have looked like over time. For example, we can look at giraffes over time, who have evolved to have had long necks. When we look as fossil records of giraffes and similar species, we see that the longer ago that animal lived, the shorter their neck was, and as time progresses, the neck gets longer. However, we also see that in general the giraffes with longer necks, regardless of time period, will have lived longer and healthier lives (we can usually tell this just by how big the fossil is), as with longer necks the animal was able to reach more food and live longer. That giraffe then reproduced and shared their longer neck traits, while those with genetic markings to make their necks shorter will have died before reproducing. Therefore, we can see all forms of evolution through fossils.
