Over many generations, directional selection will act on this population, favoring thicker coats. The curve will shift to this extreme phenotype. There will be a higher number of individuals expressing thicker undercoats. Option B. Shift toward a thicker coat.

Directional selection is one type of natural selection that responds to environmental pressures by increasing the proportion of individuals with an extreme phenotypic trait.

There must be a selective pressure or environmental pressure acting on populations to lead the species to increase the number of individuals expressing that extreme phenotype.

This selection presents more frequently in those cases in which interactions between living organisms and the environment modify in the same direction.

In the exposed example,

Directional selection will act on this snow rabbit population favoring the extreme phenotypic trait of thicker undercoat.

Over many generations, most animals will express this trait to survive colder winters.

The curve will show a shift to the extreme of the thicker coat. A higher frequency of individuals carrying thicker undercoats.

D because all the other answer are negative feedback

A  herd of buffalo running away after one of them spots a lion. Option C

Positive feedback amplifies itself and has an increasing or reinforcing effect. In this illustration, when a buffalo sees a lion, it starts to run away, which causes other buffalos to follow suit.

The response is amplified when more buffaloes begin to run, which reinforces the first response and causes the entire herd to flee the perceived threat. Positive feedback loops can quickly and significantly alter a system, either in a positive or negative way.

Answer:

The key difference between sandy soil and loamy soil is that sandy soil is less fertile due to the low content of nutrients, moisture, and humus, whereas loamy soil has more nutrients, moisture, and humus and is more fertile.

Explanation:

if it helped uh please mark me A brainliest :))

loam soil provides a well-balanced environment for plant growth, with good drainage, moisture retention, and nutrient availability.

Sandy soil, on the other hand, drains quickly but lacks moisture retention and nutrient-holding capacity, requiring additional irrigation and fertilization.

The choice of soil type depends on the specific needs of the plants and the environmental conditions in which they are grown.

Loam soil and sandy soil are two distinct types of soil with different characteristics and properties.

Loam soil is considered to be ideal for plant growth due to its balanced composition.

It is a combination of sand, silt, and clay particles. Loam soil has a granular texture and is often described as crumbly.

It has good drainage capabilities, allowing excess water to flow through while retaining enough moisture for plant roots.

The presence of silt and clay particles helps in retaining nutrients, making them available to plants.

Loam soil is fertile and provides a suitable environment for root development.

It offers a good balance of air spaces and moisture-holding capacity, promoting healthy plant growth.

Sandy soil, on the other hand, primarily consists of larger sand particles.

It has a gritty texture and is characterized by its high drainage capacity.

Sandy soil drains water quickly, which can be beneficial in preventing waterlogged conditions.

However, due to its coarse texture, it does not retain moisture well, making it prone to drought.

Sandy soil also has low nutrient retention capability, as nutrients tend to leach away with excessive watering or rainfall.

As a result, sandy soil often requires more frequent irrigation and the application of fertilizers to compensate for the lack of nutrients.

Answer:

cells duplicate so when there is no cell it cant make any

Explanation:

The statement that there must be a preexisting cell in order for a new cell to form is known as cell theory.

The scientific idea that cells make up living organisms, that they are the fundamental structural and organizational unit of all species.

They all originate from previously existing cells is known as cell theory. It was first proposed in the middle of the nineteenth century.

Because cells are the building blocks of all life, cell theory is essential for our understanding of biology.

We can have single-celled organisms like yeasts and bacteria. All living things grow and develop on the basis of cell division, or the division of a cell from one to two to four.

A vital process for life is mitosis. A cell divides into two identical daughter cells after duplicating all of its components, including its chromosomes.

Thus, the statement "cell arises from pre-existing cells" comes from cell theory.

Answer:

B. False

Explanation:

Prior to the replication of a DNA strand or molecule, the double stranded DNA molecule needs to be unwound i.e. separated into two single strands. One strand called the LEADING STRAND that runs from the 3' - 5' direction while the other strand called the LAGGING STRAND runs from the 5' - 3' direction.

The unwinding of the DNA template is carried out by an enzyme called DNA HELICASE, which binds to the DNA molecule and unwinds the double strands into two strands at the same time. This means that the unwinding into leading or lagging strand is not easier than the other since it occurs simultaneously, hence, this question is FALSE.

Yes, it is true that pitcher plants are carnivorous. Pitcher plants are a type of carnivorous plant that have evolved to obtain essential nutrients from insects and other small organisms.

The answer in True.

These plants typically grow in nutrient-poor soil conditions and have adapted to capture and digest insects as a way to supplement their nutrient intake.
The main feature of pitcher plants is their modified leaves, which form a pitcher-like structure. This structure is filled with a liquid that contains enzymes and other substances that can break down the captured prey. The rim of the pitcher, called the peristome, is slippery, causing insects to fall into the trap. Once trapped, the insects are digested, and the nutrients are absorbed by the plant.
There are several types of pitcher plants, including the North American Sarracenia, the tropical Nepenthes, and the Cephalotus from Australia. Each species has unique adaptations and trapping mechanisms that help them capture different types of prey.
In summary, pitcher plants are indeed carnivorous, as they have adapted to obtain essential nutrients from insects and other small organisms. They do so through their unique pitcher-like structures, which are designed to trap and digest prey. This adaptation allows them to thrive in nutrient-poor soil conditions.
