With parallel flow, diffusion of urea happened at regions I and II but not at regions III, IV, or V because...
A
Urea was too big to fit through the pores in regions III, IV, or V.
B
There was no concentration gradient for urea in regions III, IV, or V.
С
There was no urea in the blood in regions III, IV, and V.
D
The pore size was too small in regions III, IV, and V.

Answers

Answer 1

Answer:B

Explanation:bc all of the other ones was equal together and the concentration gradient could not spread them

Answer 2

Answer:

The correct answer is

b

Explanation:

First we can elimenate A and D because the pore size is the same.

C is wrong, there is still some urea in the blood, however is less

We are left with B which is the correct answer, i did the gizmo

Please leave a thanks and rate this answer 5 stars, you don't need an acount to do this.

Which of the following is NOT a statement from the cell theory?
O All cells come from pre-existing cells.
•All cells require water for survival.
•All living things are composed of cells.
•Cells are the basic unit of structure and function of living things.

Answers

Answer:

The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells.

Therefore, B is the answer.

"All living cells require water for survival" is NOT a statement from the cell theory.

All cells require water for survival is not a statement from the cell theory.

What is cell theory?

The cell theory is a fundamental principle in biology that states that all living organisms are composed of one or more cells and that the cell is the basic unit of life. The theory was first proposed by German scientists Matthias Schleiden and Theodor Schwann in 1839, and later refined by Rudolf Virchow in 1855. The three main principles of the cell theory are:

All living organisms are composed of one or more cells.The cell is the basic unit of life and structure for all living organisms.All cells come from pre-existing cells through the process of cell division.

The cell theory is considered one of the most important and enduring concepts in biology, and it forms the foundation for understanding the structure and function of cells and the organization of life on Earth.

A: ROCK, CLAY ,GRANITE
B: SOIL,ROCK,ORGANIC LAYER
C: CLAY,ORGANIC LAYER, GRANITE
D: GRANITE, ROCK, SOIL

Answers

soil, rock, organic layer

Explanation:

Permeability is the ability of a layer of rock to transmit fluid such as oil or water

The factors that affect the permeability of a rock layer includes the sizes of the rock particles, the ratio of the available voids to the solid mass of the rock, the presence of trapped air and the presence of organic matter

Rocks such as gravels, and  sparingly cemented sands have high permeability

The most impermeable of the options are granite and clay which for granite has large particle mass and contain no voids while clay has very fine particles packed together with little room for water

Therefore, water moves easily between layers  soil, rock, organic layer

SOIL, ROCK, ORGANIC LAYER

Consider the separate stages of an animal virus life cycle. Assemble a list of structures and processes that are unique to the virus and would make good drug targets for an antiviral agent. Explain your rationale for each choice.

Answers

Answer:

Explanation:

In order to make an antiviral agent, we need to find good drug targets, that is, to find structures and processes that are only present in the virus, so there is no harm on human cells when this antiviral agent is being applied.

In the virion of a naked virus, only nucleic acid and  protein are present forming the nucleocapsid. The nucleic acid and proteins of the capsid, specially, are found only in the virus and therefore make good drug targets. For example, we can express antibodies to recognize the proteins of the capsid and guide the immune system to destroy them.

Although virus particles are  metabolically inert, one or more key enzymes are present  within the virion in some viruses, for example, the reverse transcriptase. This enzyme is only found in viruses and if we find a way to inhibit the activity of this reverse transcriptase, like for example finding a competitor substrate, the virus will not be able to synthesize the DNA needed for its replication.

Regarding processes in the virus life cycle, they all have similar steps: first the attachment of the viral particle onto the cell, then the penetration of the virus, then the synthesis of early and intermediate enzymes using the host cell machinery, and finally the assembly of these viral components and lysis of the host cell to release new viral particles.

The attachment of a virion to a host cell is a highly  specific process. Recognition proteins on the virus recognize  specific receptors on the host cell. Substances that compete with the virion for these specific receptors can be used. If there is no attachment, there is no infection.

What is role of inheritance in breast cancer?

A woman's risk of breast cancer nearly doubles if she has a first-degree family (mother, sister, or daughter) who has the disease.

Her risk is nearly three times higher if she has two first-degree relatives. A woman's risk of developing breast cancer is considerably higher if her father or sibling had the disease.

Gene changes that are connected to breast cancer are typically acquired.  Only the breast cancer cells experience acquired DNA alterations over time.
