Because it increases the genetic variability, offering more combinations of genotypes.

3. Scientists who study the cell cycle use fluorescent dyes and lasers that enable them to measure the DNA content of individual cells. They can count the number of cells with 2N and 4N DNA content, as well as in between 2N and 4N (greater than 2N, but not quite 4N yet). a. In what phase(s) of the cell cycle will cells have 2N DNA content

Answers

Answer:

G1 phase

Explanation:

The cell cycle is divided into 2 major phases

1. The interphase

2. The m phase

The interphase, in chronological order, is further subdivided into

G1 phaseS phaseG2 phase

Cells grow and develop at the G1 phase while the G2 phase is characterized by protein synthesis in addition to continued growth.

The DNA of a cell in interphase is doubled at the S phase. This means that if a cell has a 2N amount of DNA at the beginning of the S phase, the amount of DNA at the end would have become 4N. This amount of DNA is shared into 2 daughter cells in equal amounts during mitosis or the m phase, meaning that each daughter cell would have a 2N amount of DNA before entering the interphase.

Hence, cells will have 2N DNA content in a period that spans through the end of the m phase of the cell cycle to the beginning of the S phase of the same cycle. This means that cells at the G1 phase would be the ones with 2N DNA contents.

Cell grows and prepare itself for replication in the G1 phase cell cycle. In G1 phase of cell cycle, cell is in 2n state.

Cell Cycle:

Cell cycle is the life cycle of the cell in which cell grow and divide. This completes in 2 phases,

InterphaseM- phase

Interphase:

Cell grows in this phase and prepare to divide. This includes 3 phases,

G1 phase In this phase cell, grow and prepare for replication.S- phase : Cell synthesizes its DNA via replication. In S- phase cell is in 4n stage. G-2 phase: Cell prepares itself for division.

M- phase:

Cell condenses its chromosome and divide into 2 cell.Since, cell replicates its DNA in S-phase.

Therefore, in G1 phase of cell cycle, cell is in 2n state.

Matter and energy always flow from the
in ecosystems.
A. consumers to the producers
B. heterotrophs to the autotrophs
C. autotrophs to the consumers

Answers

Answer: When organisms use organic matter for cellular respiration, ALL the goes back into carbon dioxide, water, and minerals, while ALL the energy leaves the ecosystem as heat. So matter cycles, energy flows through ecosystems. So It is C

Explanation: A. The producers generate food for themselves and others; consumers do not produce anything, instead eating producers, other consumers or both.

B. Autotrophs make food for their own use, but they make enough to support other life as well.Heterotrophs cannot make their own food, so they must eat or absorb it.

So C is correct

Matter and energy always flow from the in ecosystems from autotrophs to the consumer.

What is ecosystem?

The energy flow in the ecosystem is one of the important factors that enables the survival of such a huge number of animals. An ecosystem is made up of a network of connections between living and non-living elements.

All of the energy needed by living things is provided by the sun. About 1% of all radiant energy is absorbed by green plants and distributed throughout the ecosystem.

According to the first law of thermodynamics, energy cannot be generated or destroyed. The energy source, in this case solar energy, cannot be created or destroyed. It can only be moved from one system to another, just like a form is moved from one form to another.

Therefore, Matter and energy always flow from the in ecosystems from autotrophs to the consumer.

Can the change in cyclin concentration during mitosis be explained by the fact that the cell divides in two and thus divides the material in the cell into two smaller volumes

Answers

Answer:

No, because cell division is expected to decrease not only the net amount of cyclin molecules in daughter cells but also the volume of these daughter cells compared to the original parent cell, and therefore the concentration should be nearly equal.

Explanation:

When a cell divides to produce two daughter cells, the cell components including its previously duplicated genetic material (DNA), organelles, signaling molecules, fatty acids (lipids), proteins, etc., are distributed into daughter cells. These daughter cells have a smaller volume compared to the original parent cell. In consequence, the concentration of cellular components (including cyclin proteins) should be similar between parent cell and daughter cells.

Look at the number of deer in “predation” and “starvation” columns. What conclusions can you draw about the introduction of the wolves on these values?

Answers

Answer:

This is because when the wolves preyed on the deer, their population got regulated. Due to this, the competition for resources amongst the surviving deer population got reduced resulting in low starvation.

This is because the deer's numbers were controlled when wolves preyed on them. As a result, there was less rivalry for resources among the remaining deer population, which led to decreased hunger.

"Predation" and "starvation" are both ecological concepts related to the interactions and dynamics of populations within ecosystems.

Predation is a biological interaction in which one organism, called the predator, hunts, captures, kills, and consumes another organism, known as the prey. Predation is a common relationship in nature, observed across various taxa, such as carnivores hunting herbivores or parasites feeding on host organisms.

Starvation refers to the condition in which an organism suffers from a lack of sufficient food or nutrients required for its survival and normal functioning. When resources become scarce or unavailable, individuals within a population may not obtain enough food to sustain themselves.

Therefore, there was less rivalry for resources among the remaining deer population, which led to decreased hunger.

When there are more molecules, there will be less energy.

Answers

The more molecules move the more kinetic energy they have. I hope that helped
Energy, potential energy, is stored in the covalent bonds holding atoms together in the form of molecules. This is often called chemical energy. Except at absolute zero (the coldest temperature it is possible to reach), all molecules move. This movement is a form of kinetic energy, and the more the molecules move the more kinetic energy they have. Molecules in solids don't move much, they just vibrate. Molecules in liquids move faster and further, but they stick together enough to hold them in a small volume - the liquid. In a gas, however, the molecules are moving fast (over 1,000 miles per hour), moving in all directions, and don't stay together so they spread out and fill the available volume.

I NEED HELP The measure of how resistant a solid is to shape change when a force is applied.

Answers

Hardness is a measure of how resistant solid matter is to various kinds of permanent shape change when a force is applied Macroscopic hardness is generally characterized by strong intermolecular bonds, but the behavior of solid materials under force is complex; therefore, there are different measurements of hardness: scratch hardness, indentation hardness, and rebound hardness. Hardness is dependent on ductility, elastic stiffness, plasticity, strain, strength, toughness, viscoelasticity, and viscosity. Common examples of hard matter are ceramics, concrete, certain metals, and super hard materials, which can be contrasted with soft matter.
