Answer:
5
Explanation:
The Hardy-Weinberg equilibrium principle says that allele frequencies in a population will remain constant in the absence of the four factors that could change them. Those factors are natural selection, mutation, genetic drift, and migration (gene flow). In fact, we know they are probably always affecting populations.
Answer:
D. 5
Explanation:
There are 5 factors can be involved in changing the allele frequency.
Which of the following describes an adaptation that relates to reproduction?
A. Hawks have sharp beak to help them quickly catch their prey
B. Elks attach leaves and grasses to their antlers to help them appear larger
C. Polar bears have white fur to help them blend into their surrounding
environment
D. Whales have a thick layer of fat called blubber to help keep them warm
Answer:
B. Elks attatch leaves and grasses to their antlers to help them appear larger.
Explanation:
Reason 1: If the Elk appears larger other male Elks would be too scared to fight that Elk for a female. Reason 2: The female Elk will be more attracted to the larger male Elk even if it's largeness is fake.

What is it called when genetic information is exchanged between homologous chromosomes during prophase 1?
A. Meiosis
B. DNA Replication
C. Crossing Over
Answer:
C. Crossing Over
Explanation:
Crossing over, also called recombination, is the process by which non-sister chromatids of homologous chromosomes exchange a segment of their chromosomal material with one another. The process of crossing over occurs only in the prophase I stage of meiosis.
The process is responsible for genetic variation in the gametes produced, thereby, leading to organisms that are genetically unique.
Answer:
C. Crossing Over
Explanation:
The crossing over is called when genetic information is exchanged between homologous chromosomes during prophase 1.
Which of the following is NOT a characteristic of life?

The acceleration of an object is measure by its change in velocity per unit time. The equation for acceleration is: a =v/t. Acceleration is represented by 'a'. Velocity is represented by 'v'. Time is represented by 't'. Rearrange the equation to solve for time.
Answer:
t=v/a
Explanation:
To solve for Time
Since acceleration is change in velocity/time
a=v/t
Cross multiply
a×t=v
at=v
Divide both side by a since we want to find Time
at/a=v/a
t= v/a

why is it difficult to farm in tilted/inclined landscapes?
Answer:
Farming can lead to the loss of natural habitats.This is destroying natural habitats and changing the very nature and look of our rural landscape.
hope it helps
It is difficult to farm in an incline landscape because initial cost is high, high operational cost, Limited crops can be grown. Thus, due to these following reason, inclined farming becomes difficult.
What is vertical farming?Vertical farming is a practice of growing crops on a hilly or incline land.
However, it may have some disadvantages like high operational cost, high labor cost, only a limited number of crops can be grown.
Hence, due to these reason, tilted farming is difficult.

When a single species, such as ancestor of the Galapagos finches, has evolved into several different forms that live in different ways we say that_ has occurred.
A.adaptive radiation
B.coevolution
C.mass extinction
D.punctuated equilibrium
Answer:
A
Explanation:
In evolutionary biology, adaptive radiation is a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms, particularly when a change in the environment makes new resources available, alters biotic interactions or opens new environmental niches.
Scientists recently discovered that three different types of squid, a marine animal, previously thought to be three different species, were actually all members of one species. Their earlier ideas were based on using squid carcasses (dead bodies). The new, more accepted classification is most probably based on an analysis of

Which statement best describes a characteristic of an ecosystem
Answer:
Infrastructure
Infrastructure is an important characteristic as it influences accessibility to the environment by land managers, and tourists alike. Unfortunately it can also increase the invasive potential introduced species, such as weeds and feral animals as road vehicles are well known to act as vectors for invasion of both weeds and feral animals. On the other hand roads improve access to implement various management programs, and also provide access for land users.

fungus

A. Strangler fig
B. Boa constrictor
C. Beetle
D. Poison dart frog
Answer:
Beatle
Explanation:
Beetle in the food web below is likely to store the most energy. So, the correct option is (C).
What is Food Web?A food web is defined as the natural interconnection of food chains and is a graphical representation of what-eats in an ecological community. Food web is also known as consumer-resource system.
A food web consists of many food chains while a food chain follows only one path as animals find food. For example, Falcon eats snake, which has eaten frog, which has eaten grasshopper, which has eaten grass. Thi shows the many different pathways that plants and animals are connected.
In this, the lower trophic level organisms have more energy than the upper trophic level because only 10% of the energy flows from one trophic level to the next. In the above case, beetles have the highest energy compared to other organisms.
Thus, Beetle in the food web below is likely to store the most energy. So, the correct option is (C).
