The two factors are: crossing-over and independent assortment. Crossing over: In Prophase I of Meiosis I, homologous chromosomes line up their chromatids and “cross-over”, or exchange corresponding segments of DNA with each other. This produces genetic variation by allowing more combinations of genes to be produced.
Is a beneficial mutation always
considered beneficial?
A. No, it depends on the organism's personal goals.
B. No, it depends on the organism's environment.
C. Yes, it will always increase the organism's chances of
survival.
D. Yes, it will always increase the organism's chances of
finding a mate.
Answer:
B
Explanation:
B is the correct answer because the environment effects how the body has to adapt.
A beneficial mutation is not always considered beneficial because: (B) It depends on the organism's environment.
While a beneficial mutation can provide advantages to an organism in certain environments or circumstances, its benefits may not be universal. The suitability of a mutation depends on the specific environmental conditions in which the organism finds itself. Organisms inhabit diverse environments with varying challenges and selective pressures.
A mutation is a change in the DNA sequence of an organism's genetic material. Mutations can occur naturally due to errors during DNA replication or as a result of external factors such as exposure to radiation, chemicals, or certain environmental conditions.

what's the definition of speciation
Answer:
The forming of a new species within the course of evolution.
Imagine that you are a baseball, and are being used in a game. Write a story that tells about the different forces you feel during the game. Remember that any time an object’s motion changes, there must be some kind of force acting on it.
Explanation:
It's hard to believe, but everything in the world is in motion, all the time. Even things that look perfectly still are packed with atoms that are vibrating with energy. Understanding how motion works was one of the great milestones of science and it's credited to the brilliant English physicist Sir Isaac Newton. His laws of motion, written over 300 years ago, were so well stated that scientists still use them in most situations today. The basic idea Newton taught us is that motion is caused by forces—which is easy enough to understand: kick a ball (the force) and it flies into the air (the motion). But forces don't always make things move: a bridge has lots of forces acting on it, but it doesn't go anywhere. Also, the "motion" forces produce is sometimes a shift in the direction in which something is moving or a change in its shape. So what exactly are forces and how they do they produce these different kinds of motion? It's time to take a closer look at the science of moving things!

What role do bacteria play in the nitrogen cycle?
Question: What role do bacteria play in the nitrogen cycle?
Explanation/answer: Bacteria plays a central role: Nitrogen-fixing bacteria, which convert atmospheric nitrogen to nitrates. Bacteria of decay, which conconvertsert decaying nitrogen waste to ammonia. Nitrifying bacteria, which convert ammonia to nitrates/nitrites.

Answer:
Nitrogen-fixing bacteria
Explanation:
Nitrogen-fixing bacteria
The role of nitrogen-fixing bacteria is to supply plants with the vital nutrient that they cannot obtain from the air themselves. Nitrogen-fixing microorganisms do what crops can’t – get assimilative N for them. Bacteria take it from the air as a gas and release it to the soil, prima

Peppered moths come in two color variations, as shown below.
Prior to the Industrial Revolution, the majority of the population in England consisted of the light colored variation. The dark colored moth became the dominant variation by the end of the 20th century and remained so for almost 100 years. Today, the light colored variation is dominant again.
What is the best explanation for this?
A. Populations with two variations have a better chance of survival than populations with more.
B. A single variation can be beneficial under some conditions and harmful under other conditions.
C. One variation will always be harmful, and the other will always be beneficial.
D. A single variation can be beneficial in all conditions or harmful in all conditions.
The answer, I do believe, should be option B. Here's my reasoning...
The question doesn't ask about a bunch of other species and how the moth variations relate to the survivability of many species, so I think that rules out option A. Option C is too black-and-white, because the explanation above simply states how a moth was able to survive better on different color variations. The last option, D, is also too black-and-white. So I believe that the answer is B, because sometimes, like prior to the Industrial Revolution, the one variation is better (as seen in the upswing of dominance in different variations).

The breakdown of phospho-creatine by creatine kinase neither occurs in the cytosol (cytoplasm) nor requires oxygen.
What is creatine kinase?Creatine kinase (CK) is a crucial catalytic enzyme required to catalyze the conversion of phosphocreatine.
During this process of conversion, ATP (which is considered the energy coin of the cells) is generated.
Creatine kinase (CK) is a fundamental enzyme to produce ATP in a quick mode and thus generate energy.
