Biology-Calculate The Fluid Pressure At Piston A.-Calculate The Force Exerted On Piston B.-Which Principle

Answers

Answer 1

Answer:

80N

Explanation:

in both sides, pressure is the alwyays the same whatever the area is..

First we calculate the pressure at piston A:

P= F÷a

given that,

#F= 20N

#a=1m^2

P= 20÷1

P= 20 Pa.

At piston B:

pressure is the same = 20Pa

Area= 4m^2

P=F/a

F= P×a

F= 20 × 4

F= 80N

A receptor site that a molecule can bind to that changes the shape of the active site is called a(n)
a) allosteric site
b) active site
c) disulphide bridge
d) MHC receptor

Answers

Answer:

a) allosteric site

Explanation:

An allosteric site is a site on an enzyme other than the active site where a molecule that is not a substrate binds. This changes the shape of the enzyme, making it harder for the substrate to bind and inhibits enzyme activity.

Why are the Kreb's cycle and ETC
considered aerobic processes?

Answers

Answer:

Without oxygen, the electron transport chain becomes jammed with electrons. Consequently, NAD cannot be produced, thereby causing glycolysis to produce lactic acid instead of pyruvate, which is a necessary component of the Krebs Cycle. Thus, the Krebs cycle is heavily dependent on oxygen, deeming it an aerobic process.

The statement explains the importance of enzymes that check for and repair mistakes during DNA replication is the enzymes prevent many genetic mutations from being expressed.

What is RNA polymerase?

RNA polymerase is an enzyme that aids in the transcription of DNA into RNA during transcript in the nucleus. The enzymes prevent many genetic mutations from being expressed.

Primase is an enzyme that synthesizes short RNA sequences called primers. These primers serve as a starting point for DNA synthesis during replication as the DNA polymerases cannot begin the synthesis of the new strand, they only extend it after primase begins it and primase produces RNA molecules, the enzyme can be said to be a type of RNA polymerase.

Therefore, The statement explains the importance of enzymes that check for and repair mistakes during DNA replication is the enzymes prevent many genetic mutations from being expressed.

In order from smallest to largest, the ecological levels of organization are
A: biome, ecosystem, community, population, individual

B:community, individual, population, ecosystem, biome

C: individual, population, ecosystem, community, biome

D: individual, populations, community, ecosystem, biome

Answers

Answer:

D: individual, populations, community, ecosystem, biome

In order from smallest to largest, the ecological levels of organization are individual, populations, community, ecosystem, biome. So, the correct option is (D).

What is an Ecosystem ?

Ecosystems are the complex living organisms and their physical environment and all their concerned correlation in a specific unit of space.

An ecosystem can be classified as

1.Abiotic constituents

It consists of minerals, climate, soil, water, sunlight, and all other non living materials.

2. Biotic constituents

It includes all its living organisms.

By combining these constituents together generates two important forces:

The flow of energy from the ecosystem The galloping of nutrients within the ecosystem.

Ecosystems have varied sizes like some are tiny enough to be encompassed within single water droplets while others are big enough to embody entire topography and regions.

Organic matter engendered by autotrophs directly or indirectly bolster heterotrophic organisms. Heterotrophs are the consumers of the ecosystem which cannot make their own food. They utilize, reorganize, and finally decompose the complex organic substance made up from autotrophs.

Thus, in order from smallest to largest, the ecological levels of organization are individual, populations, community, ecosystem, biome. So, the correct option is (D).

There is a relationship between the number of prey organisms and the number of predator organisms in an ecosystem. Identify this relationship and explain how it occurs.

Answers

Answer:

This relation should be called Predator-Prey relationship. In the predator prey relationship, one species is feeding on the other species. The prey species is the animal being fed on, and the predator is the animal being fed. they affect the success and survival of each other’s species. The predator prey relationships greatly affect the populations of each species, for example if we take lynx as predator and hare as prey after some time the population of hare will start declining and population of lynx will increase because hare is being EATEN and lynx is the predator here.

What was known before Franklin and Wilkins conducted their studies of DNA? Select three options.

DNA is found in the nucleus of a cell.
The human genetic code is made of 50,000 genes.
Organisms store and transmit genetic information.
DNA has a double-helix structure.
Cells contain protein molecules.

Answers

The correct answer will be-

  1. DNA is found in the nucleus of a cell

   2. Organisms store and transmit genetic information

   3. Cells contain protein molecules.

Explanation:

The study of DNA started much before the discoveries of Rosalind Franklin and Maurice Wilkins.

Nucleus of cell was discovered by Robert Brown in 1831 but the material present inside the nucleus called "nuclein" (DNA) came from the studies of Johann Friedrich Miescher in 1869.

Proteins as a constituent of cell were discovered by the experimental analysis of Gerhardus Johannes Mulder in 1837.

DNA as a genetic material came from the experimental studies of Frederick Griffith in 1928, Oswald Avery, Maclyn McCarty, and Colin MacLeod in 1944, and Hershey and Chase in 1952.

Franklin and Maurice Wilkins are known for their work on the the structure of DNA as they were able to produce high-resolution X-ray photographs of DNA fibres called Photo 51 in 1952 using X-ray diffraction technique. By 1953 Franklin concluded concluded that DNA shows helical structure with phosphates on outer side.

Thus, 1. DNA is found in the nucleus of a cell

        2. Organisms store and transmit genetic information

        3. Cells contain protein molecules.

            are the correct options.
