A trade of chromosome segments among non-sister homologous chromatids happens and is referred to as crossing over.
Crossover happens while chromosomes, usually homologous times of the equal chromosome, spoil after which reconnect however to the specific quit piece. If they spoil on the equal location or locus withinside the collection of base pairs, the end result is an trade of genes, referred to as genetic recombination.
What are homologous chromosome?Homologous chromosomes are made from chromosome pairs of about the equal length, centromere position, and marking pattern, for genes with the equal corresponding loci.
Thus it s well expalined.

prokaryotic cells have nulcleus
Answer:
not nucleus, only nucleoid
Answer:
Prokaryotic cells are surrounded by a plasma membrane, but they have no internal membrane-bound organelles within their cytoplasm. The absence of a nucleus and other membrane-bound organelles differentiates prokaryotes from another class of organisms called eukaryotes.

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.

Answer:
This stored form of glucose is made up of many connected glucose molecules and is called glycogen. When the body needs a quick boost of energy or when the body isn't getting glucose from food, glycogen is broken down to release glucose into the bloodstream to be used as fuel for the cells.

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.

A cross between a yellow snake and a blue snake produces offspring that are all green. What type of inheritance is this?
Answer:
co dominance
Explanation:
codominance is a type of inheritance in which both allels are dominat over each other and the two allels are expressed to an equal degree in an offspring,that is why the cross between yellow and blue snake give another green colour offsprings in stead of giving all blue or all yellow offsprings depending on which allel is dominant.
as example we can take human blood group AB which is inherited from blood group A and B and both allel A and B are dominant over each other.

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.
Energy in an ecosystem flows directly from _______. a. producers to tertiary consumers b. producers to secondary consumers c. tertiary consumers to secondary consumers d. secondary consumers to tertiary consumers please select the best answer from the choices provided a b c d
Answer:
A.
Explanation:
Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next.
Energy in an ecosystem flows directly from producers to tertiary consumers. So, the correct option is A.
What do you mean by Ecosystem?An Ecosystem may be defined as an area where organisms of different species are present together in a given time and interact with one another in order to survive.
In an ecosystem, producers produce the energy in the presence of sunlight through the process of photosynthesis. And then passes its energy to primary consumers (herbivores), then primary consumer passes their energy to secondary consumers (carnivores), then secondary consumers pass their energy to tertiary consumers. According to Lindeman, only 10% of energy get transferred to each trophic level.
Therefore, Energy in an ecosystem flows directly from producers to tertiary consumers.

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
