<h3><u>Answer;</u></h3>
When particles were pulled together so tightly they combined.
<h3><u>Explanation</u>;</h3>
- The solar nebular hypothesis describes the formation of our solar system from a nebula cloud made from a collection of dust and gas.
- It is believed that the sun, planets, moons, and asteroids were formed around the same time around 4.5 billion years ago from a nebula.
- According to this theory, the Sun and all the planets of our Solar System began as a giant cloud of molecular gas and dust.
A. The surface area to volume ratio increases
Answer:
Epithelial tissue is composed of cells laid together in sheets with the cells tightly connected to one another. Epithelial layers are avascular, but innervated.
Epithelial cells have two surfaces that differ in both structure and function.
The epithelial cells are nourished by substances diffusing from blood vessels in the underlying connective tissue. One side of the epithelial cell is oriented towards the surface of the tissue, body cavity, or external environment and the other surface is joined to a basement membrane. The basement layer is non-cellular in nature and helps to cement the epithelial tissue to the underlying structures.
Answer:ATP, Endergonic, Phosphate group, ATP synthase, Exergonic
Explanation:
1. ATP is the energy currency of the cell. The energy released from the hydrolysis of ATP is use to drive cellular work.
2. ATP are used to drive endergonic reaction. Endergonic reaction are energy requiring hence ATP is hydroxyze to release energy to power endergonic reaction.
3.ATP is formed when a phosphate group is transferred to ADP. Which is an example of endergonic reaction
ADP+Pi+free energy→ATP+H2O.
4. The oxidative phosphorylation of ADP to ATP is catalyze by the enzyme ATP synthase.
5. ATP synthesis is an endergonic reaction in which free energy is needed to phosphorylate ADP to ATP and the reaction is driven by Exergonic reaction.
Answer:
a. do not immediately increase in number when placed in a culture
Explanation:
When bacteria placed in a new culture it shows a pattern of growth which is known as sigmoid growth. It has four phases lag, log, stationary, and death.
The lag phase occurs because bacteria do not start dividing immediately just after the placed in the new culture media because bacteria first adapt to the new environment and prepare enzymes needed for metabolizing the new substrate.
As the bacteria pass this lag phase it starts to divide at an exponential rate. Therefore it is true that most bacteria do not increase in number immediately after placed in a new culture.
