A newly created cell and its nucleus go through a series of modifications known as prophase and interphase in order to prepare for cell division. It is also known as the preparatory phase.
Exists the M phase?When a cell is in the M phase, it divides, first through nuclear division (mitosis), then through cytoplasmic division (cytokinesis). The DNA is replicated in the earlier S phase, and cohesins keep each replicated chromosome's two copies (known as sister chromatids) bound to one another.
Is the M phase the longest phase?Prophase is the first and longest phase of mitosis. Chromatin gathers into chromosomes and the nuclear envelope, which is the membrane that encloses the nucleus, disintegrates during prophase. DNA synthesis or replication takes place during the S phase of a cell cycle, which happens during interphase and comes before mitosis or meiosis. Before a cell starts mitosis or meiosis.

Organisms that use energy to control their internal conditions are
Answer:
regulators
Explanation:
regulators use their metabolism to control their internal environment
When a pregnant woman ingests toxins such as alcohol and
nicotine, the embryo is put at risk because these toxins can
1) diffuse from the mother's blood into the embryo's
blood within the placenta
2) enter the embryo when it eats
3) transfer to the embryo since the mother's blood
normally mixes with the embryo's blood m the placenta
4) enter the uterus through the mother's navel
How does the body structure evolve for animals as they transmit between the two environments?
Answer:
Biologists believe that new species evolve from existing species by a process called natural selection. ... Organisms that inherit that favorable new gene are likely to become more abundant than others of the species. Sometimes the population of a species becomes separated into two areas, by geography or by climate.

What is the relationship between DNA, a gene, and a chromosome?
A. A chromosome contains hundreds of genes, which are composed of DNA
B. A chromosome contains hundreds of genes, which are composed of protein
C. A gene contains hundreds of chromosomes, which are composed of protein
D. A gene contains hundreds of chromosomes, which are composed of DNA
Answer:
A
Explanation:
The correct option is (a). Chromosomes are long thread-like structures present in the nucleus of a cell which contains hereditary information of the cell (genes). Genes are the part of a chromosome and made up of DNA.
Answer:

Which description accurately describes the cell membrane?
a. a single permeable layer of phospholipids that have hydrophobic heads and hydrophilic tails
b. a semi-permeable double layer of phospholipids that have hydrophilic heads and hydrophobic tails
c. a single permeable layer of phospholipids that have hydrophilic heads and hydrophobic tails
d. a semi-permeable double layer of phospholipids that have hydrophobic heads and hydrophilic tails
e. a barrier of polypeptides that prevents molecules from entering or leaving the cell
Answer:
b. a semi-permeable double layer of phospholipids that have hydrophilic heads and hydrophobic tails
Explanation:
B is correct as the cell membrane is selectively semi-permeable. It is selectively semi-permeable because this quality allows it to control what can and can't enter the cell, and how it does so.
The cell membrane also has a phospholipid bi-layer comprised of a double layer of phospholipids which have hydrophilic head and hydrophobic tails. This is because the heads are made of phosphate and are polar and are therefore attracted to water (hydrophilic), while the tails are made of lipids (i.e. fats, oils) which do not mix with water and are therefore hydrophobic.
The properties of each phospholipid is also why they form the double layer structure, the hydrophilic heads naturally face outwards into the water and protect the hydrophobic tails on the inside.

why animals need to move quickly
Answer:
Animals move for a variety of reasons, such as to find food, a mate, a suitable microhabitat, or to escape predators. For many animals, the ability to move is essential for survival and, as a result, natural selection has shaped the locomotion methods and mechanisms used by moving organisms.

Part C Firefly luciferase is the enzyme that allows fireflies to illuminate their abdomens. Because this light generation is an ATP-requiring reaction, firefly luciferase can be used to test for the presence of ATP. In this way, luciferase can test for the presence of life. The coupled reactions are 1.2.luciferin+O2ATP⇌⇌oxyluciferin+lightAMP+PPiΔG∘=−31.6 kJ/mol If the overall ΔG∘ of the coupled reaction is -4.80 kJ/mol , what is the equilibrium constant, K, of the first reaction at 6 ∘C ?
Answer:
K = 9.620 × 10⁻⁶
Explanation:
From the given information:
Temperature T= 6° C
= (273 + 6)K
= 279 K
The correct and well presentation of the reactions are:
1. [tex]Luciferin + O_2[/tex] ⇆ oxyluciferin + light ΔG₁°
2. ATP ⇄ AMP + PP[tex]_i[/tex] ΔG₂° = -31.6 kJ/mol
The overall ΔG° = -4.80 kJ/mol
Let's first determine the ΔG₁° for the equation (1)
ΔG° = ΔG₁° + ΔG₂°
- ΔG₁° = - ΔG° + ΔG₂°
ΔG₁° = ΔG° - ΔG₂°
ΔG₁° = ( -4.80 - (-31.6) ) kJ/mol
ΔG₁° = 26.8 kJ/mol
Using the formula:
ΔG° = -RTIn K
[tex]In \ K =\dfrac{-\Delta G^0}{RT} \\ \\ log \ K = -\dfrac{\Delta G^0}{2.303RT}[/tex]
[tex]log \ K = -\dfrac{\Delta G_1^0}{2.303RT} \\ \\ log \ K = -\dfrac{26.8 \times 10^3 \ J/mol}{2.303\times 8.314 \ J/mol/K \times 279 \ K} \\ \\ log \ K =- 5.017[/tex]
K = antilog (-5.017)
K = 9.620 × 10⁻⁶

This paramecium has a nucleus and is comprised of one cell. Which terms best describe this organism?
Answer: The term that best describes this organism is that it's a UNICELLULAR PROTISTA.
Explanation:
Unicellular organisms are that are made up of just one cell. They are also called single- celled organisms. Examples of unicellular organisms include: Amoeba, chlamydomonas and paramecium.
The paramecium is a protist which is SINGLE-CELLED and is made up of eucaryotic cells in which the cell structure is complex with a well-defined NUCLEUS.
The structure of this organism helps it to survive in its environment. It has cilia that helps it move food into its gullet.
The food vacuole circulate along a definite path in the cytoplasm. The anterior and posterior contractile vacuole, with radiating channels draining into them, helps to get rid of excess water from the body. The food vacuoles circulate along a definite path in the cytoplasm. The anterior and posterior contractile vacuole, with radiating channels draining into them, helps to get rid of excess water from the body.
The NUCLEUS is used by the organism for sexual reproduction. This occurs in a process known as conjugation whereby the whole organism pair with another similar whole organism and exchange their nuclei.

A coin is flipped 150 times. The results of the experiment are shown in the following table:
Heads Tails
84 66
Which of the following statements best describes the experimental probability of getting heads?
It is equal to the theoretical probability.
It is 6% lower than the theoretical probability.
It is 6% higher than the theoretical probability.
The experimental probability cannot be concluded from the data in the table.
Answer:
it is 6% higher than the theoretical probability.
Explanation:
we start with out experimental.
84 times heads out of 150.
84/150 = 56.
=56%
now for theoretical.
since there are 2 sides, there are 2 chances of randomly getting heads.
1/2 = 50%
56% > 50%
therefore your answer is that it is 6% higher. hope my explanation helps!
