Which Statement Is True About Biodiversity?

Answers

Answer 1

Answer:

A or C

Explanation:

B and D are plain illogical. C is definately true, but since it's a little too broad I'm thinking that it would be A, since natural disasters can decrease populations which can destroy genetic diversity (see founders effect).

Which organisms do you think might be more closely related to each other: a dog and a turtle or a dog and a silkworm

Answers

Answer:

Most likely a dog and a turtle.

Explanation:

A Dog and a Turtle organisms do you think might be more closely related to each other, So, the correct option is A.

What is an organism?

An organism is defined as any living system which functions as an individual unit where all living things are made up of cells. The concept of organism is based on the concept of the minimum functional unit of life.

Biological organisms are defined as living things capable of responding to stimuli, reproduction, development and homeostasis which are classified by taxonomy into specified groups such as multicellular animals, plants and fungi; or unicellular microorganisms such as protists, bacteria and archaea.

A Dog and a Turtle organisms do you think might be more closely related to each other as both have four legs and belongs to Phylum Chordata.

So, the correct option is A.

Complete question:

Homogenization of rat liver cells results in the rupture of the cell membranes. Centrifugation of this homogenate compacts some of the homogenates into a pellet at the bottom of the centrifuge tube. Bathing this pellet with a solution containing succinate (a four-carbon organic compound), phosphate ions, oxygen, and ADP yields metabolic activity, including the production of ATP and the uptake of oxygen. This pellet most likely contains

1. peroxisomes

2. mitochondria

3. lysosome

4. Golgi complex

5. endoplasmic reticulum

Answer:

2. Mitochondria

Explanation:

Mitochondria are one of the biggest organelles in the cell. They degrade organic molecules, releasing chemical energy from their bindings through a process that consumes oxygen: cellular respiration.

The released energy is stored as ATP through the cellular respiration process and then is used in other cellular activities.

Mitochondria are more grouped in areas or tissues with higher energetical requirements.

As cellular respiration characterizes by consuming oxygen and producing ATP, we can assume that the pellet mostly contains mitochondria.

By considering the components of the pellet, we can deduce that it most likely contains MITOCHONDRIA.

Cellular respiration is a series of reactions by which aerobic cells consume oxygen and nutrients (e.g. glucose) to produce ATP and carbon dioxide.

Cellular respiration has three sequential steps: glycolysis, the Krebs cycle and oxidative phosphorylation.

Mitochondria are the energy center of the eukaryotic cells. The Krebs cycle and oxidative phosphorylation occur in the mitochondria, while glycolysis occurs in the cytoplasm.

The Krebs cycle produces a four-carbon molecule known as succinate.

Adenosine triphosphate (ATP), the energy coin of the cell, is produced from ADP and phosphate (Pi) in the three stages of cellular respiration.

Finally, oxygen is consumed during oxidative phosphorylation.

In conclusion, by considering the components of the pellet, we can deduce that it most likely contains MITOCHONDRIA.

how are two identical DNA molecules formed

Answers

Answer:

Explanation:

DNA is a double stranded molecule. When DNA is copied the two strand of DNA (old strands) separate and new nucleotides match up with the two separated strands. This process creates two identical double stranded DNA molecules are formed. Each DNA molecule contains one strand of the original DNA molecule and one newly synthesized (made) strand.

hope it helps :)

Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin. Several enzymes and proteins then work together to prepare, or prime, the strands for duplication. Finally, a special enzyme called DNA polymerase organizes the assembly of the new DNA strands. The following description of this three-stage process applies generally to all cells, but specific variations within the process may occur depending on organism and cell type.

Mutation is a natural process that changes a DNA sequence. Most DNA changes Faul in a large areas of the genome that sits between genes, and usually they have no effect. When variation occur within jeans, there is more often a consequence, but even then mutations only really cause death or disease. Mutations also generates new variations that can give an individual A survival advantage.

Answers

Answer:

The correct answer is -

1) point mutation

2) deletion

3) inversion

4) frameshift mutation.

Explanation:

Point mutation or substitution mutation is a genetic mutation that takes place when there is a change in a single base nucleotide, it can be replaced with other nucleotides from a DNA or RNA sequence of an organism's genome.

Deletion is a genetic mutation that occurs when there is a loss of a segment of a chromosome. If the particular segment is responsible for an important protein or gene the offspring have to be with one copy only therefore, it is considered a bad mutation.

When there is a reversal of the segment of a chromosome occurs a change takes place in genetic material which is known as the inversion type of genetic mutation.

If any of the above mutations take place including deletion, inversion, replacement or insertion in one or more nucleotides to make a change in the amino acid sequence from the site of mutation forward is frameshift mutation.

Why couldn't yeast use both sugar and artificial sweetener for cell respiration?

Answers

Yeast, sugar eating fungus, use oxygen to release the energy from sugar, much like humans, in the process called "respiration". The more sugar there is, the more active the yeast will be and the faster it will grow. Yeast feeds on sucrose, fructose, glucose, and maltose, which it converts to cellular energy through alcoholic fermentation.
Sugar is more suitable for respiration.
The artificial sweeteners are less effective at promoting yeast respiration than sucrose.

Yeast couldn't use both sugar and artificial sweetener for cell respiration because of the low calorie content of artificial sweetener.

What is artificial sweetener?Chemicals called artificial sweetening agents are used to sweeten food. They do not, however, provide our bodies with extra calories.Which one will have better yield?The sugars will have better yield because natural sugars like sucrose have more calories than artificial sugars.This increased energy will allow the yeast to metabolize faster and hence more carbon-dioxide is released.What is cellular respiration?

"Cellular respiration is a series of metabolic processes that take place inside of cells to transform biochemical energy from food into a compound called as adenosine triphosphate (ATP)."

Mercury is often used in thermometers. The mercury sits in a bulb on the bottom of the thermometer and rises up a thin capillary tube as the temperature rises. Suppose a mercury thermometer contains 3.380g of mercury and has a capillary that is 0.200mm in diameter. How far does the mercury rise in the capillary when the temperature changes from 0.0 0C to 25.0 0C

Answers

Answer:

3.5 cm

Explanation:

Mass of mercury = 3.380

Diameter = 0.200

At t = 0 and 25 degrees we have 13.596 and 13.543 as density

At 0 degree = v = 3.380/13.596 = 0.2485

At 25 degrees = 3.380/13.534 = 0.2497

We use volume of cylinder to get height

At 0⁰ height = 7.91

At 25⁰ = 7.944

The difference in height = 0.035

Multiply by 100 = 0.35 x100

= 3.5cm
