Team of scientists is studying several plant species that they think could become new farm crops. The scientists want to apply selective breeding to develop one of the species into useful crop plants. Which property of a plant species would be MOST USEFUL for meeting the scientists' goal? A. very low genetic variation B. very high genetic variation C. producing only a few fruits and seeds each growing season
Answers
Answer:
B. very high genetic variation
Explanation:
Selective breeding is the process by which crops or animals with desired phenotypic traits are chosen to produce offspring, which will contain the desired qualities. In this case, a group of scientists is trying to apply the principles of selective breeding to develop a particular crop plant.
This goal of producing a useful crop plant by the scientists can only be achieved when the plant species in question possess a HIGH GENETIC VARIATION i.e. difference in genetic constitution of individuals of the same species. This allows the individuals in the population to survive better.

What is the Precambrian time period?From roughly 4.6 billion years ago, when Earth first started to form, to the start of the Cambrian Period, 541 million years ago, is the Precambrian Period. It is the earliest era which is followed by the Cambrian period.
Large objects bombarded the Precambrian Earth, the crust was split into the first continents and ocean basins, crustal plates were mobilized, the atmosphere changed from reducing to oxidizing, and early life began and evolved. Climate and geologic events are responsible for the end of this period.
During this period, the amount of oxygen increased rapidly. Therefore, option C is correct.

Why do we need friction in our world?
Answers
Friction is a force that works against motion. While walking, friction helps us maintain our stability and prevents us from slipping. Friction also works the same way with cars and vehicles in general, preventing them from skidding and helping them stop when the brakes are applied. We also need friction to make a fire.
Without friction between the shoes and the ground, you cannot walk properly. If there is no friction, all of us would be sliding around without any control over ourselves. While walking, you're pushing your foot back as you try to step forward. Friction holds your shoe to the ground so you can walk around.

How is antibiotic resistance related to natural selection?
Answers
Answer:
Antibiotic resistance is a consequence of evolution via natural selection. The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will be a fully resistant generation.

d. Mutations are essential for evolution to occur because they are respo

Answers
Answer: option C.
Mutations are essential for evolution to occur because they produce variations within a population.
Explanation:
This is because Mutation refer to change in the genetic content or DNA composition of organisms. Therefore , for evolution to occur there must be Mutation because it is the main source of genetic variation or causes genetic variation needed for evolution.
Mutation is important as the basics of evolution because it produce a new DNA sequence for a gene function, which lead to the formation of new allele.
A major function of the human urinary bladder is
A) storing urine until it is eliminated
B) releasing urine directly into the bloodstream
C) transforming urine into a nitrogenous waste
D) filtering urine out of the blood
Answers
The bladder stores urine, allowing urination to be infrequent and controlled. The bladder is lined by layers of muscle tissue that stretch to hold urine. The normal capacity of the bladder is 400-600 mL. During urination, the bladder muscles squeeze, and two sphincters (valves) open to allow urine to flow out.

How does the lipid portion help maintain water concentration on each side of the bilateral?
Answers
Answer:
Explanation:The phospholipid bilayer formed by these interactions makes a good barrier between the interior and exterior of the cell, because water and other polar or charged substances cannot easily cross the hydrophobic core of the membrane. Can water cross the plasma membrane at all?
It also helps the cell move things in and out. The cell membrane is made of what is called a phospholipid bilayer, which means it has two layers of phospholipids. ... This allows the phosphates to be exposed to water, either in the cell or the environment, while the lipids are protected from water Lipids are essential for all life on Earth. They play many important roles in maintaining the health of an organism. Arguably the most important function lipids perform is as the building blocks of cellular membranes. Other functions include energy storage, insulation, cellular communication and protection.Large quantities of water molecules constantly move across cell membranes by simple diffusion, often facilitated by movement through membrane proteins, including aquaporins. In general, net movement of water into or out of cells is negligible.

What makes one animal more adapted than another?
1. It has acclimatized to its environment during its lifetime.
2. Its phenotype is better suited to its environment.
3. It is more fit, regardless of environment.
4. It will live longer than most other individuals.
Answers
Answer:
The answer is 2. its phenotype is better suited to its environment.
Explanation:
Adaptation is the process by which animals pass on genes that make their offspring increasingly better at surviving and reproducing in their given environment. and also I took the quiz.
Its phenotype is better suited to its environment," is generally the most significant factor. Therefore, option (2) is correct.
What is adaptation?Adaptation is a biological process by which a population of organisms becomes better suited to its environment over time. This process involves changes in an organism's behavioral, anatomical, or physiological traits that enable it to survive and reproduce in its environment.
Adaptations may be the result of natural selection, where certain traits that confer an advantage in the environment are passed on to offspring, leading to evolutionary changes in the population. Adaptations can be observed at different levels, from the molecular to the ecosystem, and they are crucial for the survival and success of species in their environments.

Can two different species of fungi from two different genus' mutate into a new species? i just want to know if it's a possibility, and how gigantic or slim the chances are of it happening.
Answers
Answer:
Yes, it is possible.
Explanation:
In this case, I'm guessing you mean breeding.
If that's the case, they will form hybrids.
Between two different species, inter specific hybrids will be formed.
Between two different genus, intergeneric hybrids will be formed.
There's even rare cases of breeding between two families.
So while it is possible for different species and/or genus to breed and form new species, in interspecific breeding for instance, they will have features similar to the parents but turn out sterile.
So to answer your question, it is possible.
