Answers

Answer 1

Answer: Density=Mass/Volume

Explanation:

Answer 2

Answer:

[tex]density = \frac{mass}{volume} [/tex]

explanation :

here some examples

the mass of 20 cm³ of mercury is 272g. calculate it density of mercury.

[tex]density \\ = \frac{mass}{volume} = \frac{272g}{ {20cm}^{3} } [/tex]

Besides poaching, what other major factor is causing a decline in elephant populations?

Answers

Answer:Habitat Loss and conflict with communities

Explanation: Habitat loss and conflict with communities

Most elephant habitat still extends outside protected areas, and the rapid growth of human populations and the extension of agriculture into rangelands and forests formerly considered unsuitable for farming mean that elephant habitat is continuing to be lost.

Increasing conflict with people

As human populations expand, more land is being converted to agriculture. So elephant habitat is shrinking and becoming more fragmented, and people and elephants are increasingly coming into contact - and conflict - with each other.

Elephants sometimes raid farmers’ fields and damage their crops – affecting the farmers’ livelihoods – and may even kill people. Elephants are sometimes killed in retaliation.

With human populations continuing to grow across their range, habitat loss and degradation - and conflict with communities - will remain major threats to elephants' survival.

Besides poaching other major factor is causing a decline in elephant populations is habitat Loss and conflict with communities.

What are the reason behind the decline of the population of elephants?

The reason behind the decline of the population of elephants are poaching, besides poaching other major factor is causing a decline in elephant populations is habitat Loss and conflict with communities.The logistics growth curve has been defined as the population per capita growth rate is decreases and get smaller and the size of population increases maximum applied by resources which are limited  in the environment which is known as the K that has been carrying capacity.

The logistics population growth has been  represented by the logistic growth curve on a line graph and the shape of the curve has S - shaped that represents the slow increase, and rapid growth in the population and after that there has been reduction in the growth.

The best example of the logistics growth has observed in the wild population that includes the sheep as well as harbor seals. In both of the cases the number of the population has been increases and carrying capacity for small period of time.

Therefore, Besides poaching other major factor is causing a decline in elephant populations is habitat Loss and conflict with communities.

When two plants, one with homozygous yellow leaves (YY) and one with heterozygous yellow leaves (Yy) are crossed, then the offspring will have yellow leaves and none of the offspring will have red colored leaves as this is a recessive trait and it requires to be present in homozygous condition to show its effect.

Which of the following statements is true for a molecule that is phosphorylated?
A) It has been reduced as a result of a redox reaction involving the loss of an inorganic phosphate.
B) It has a decreased chemical energy and is less likely to provide energy for cellular work.
C) It has been oxidized as a result of a redox reaction involving the gain of an inorganic phosphate .
D) It has increased chemical potential energy that may be used to do cellular work.

Answers

Answer:

The correct appropriate is Option D.

Explanation:

The phosphorylation mechanism of both a chemical compound, either through inorganic phosphate conversion other than by phosphate conversion from yet another biological phosphate.  Those have improved chemical energy capacity which could be used to do cellular function.  

Some other possible alternatives are not connected to the situation described. So, the solution above is the right one.

The statement 'it has increased chemical potential energy that may be used to do cellular work.' is TRUE about a molecule that is phosphorylated (Option D).

Phosphorylation is a posttranslational protein modification that plays a fundamental role in many cellular processes.

Phosphorylation increases the potential energy of a molecule by adding a phosphate group that contains a high-energy phosphate bond.

The energy released by this phosphate bond can be used to drive many cellular processes.

In conclusion, the statement 'it has increased chemical potential energy that may be used to do cellular work.' is TRUE about a molecule that is phosphorylated (Option D).

Answer:

We divide ER into two types because Smooth ER(SER) do not have ribosomes and Rough ER(RER) have ribosome thus former is also called Agranulated ER and Latter is called Granulated ER. SER is not involved in protein synthesis its main function is synthesis of lipids carbs steroid thus it is found in Adipose cells, interstitial cells, liver cells. RER have ribosomes so they are involved in protein synthesis so they are present in protein synthesising cells such as salivary glands and pancreas.

When do enzymes stop reacting to the substrates?

Answers

This structure is held together by weak forces between the amino acid molecules in the chain. High temperatures will break these forces. The enzyme, including its active site, will change shape and the substrate no longer fit. The rate of reaction will be affected, or the reaction will stop.

Answer:

If the reaction is divalent metal ion-dependent, you can stop the reaction by adding an excess of EDTA to bind the metal.

You can kill the protein by adding perchloric acid, then precipitate the perchlorate with an equivalent amount of potassium carbonate, leaving nothing but carbonic acid in the supernatant, which bubbles off as carbon dioxide. Centrifuge the sample and take the supernatant to analyze for the product.

A rather slow method is ultrafiltration, using a micro-centrifugal ultrafilter (e.g. Microcon) with a molecular weigh cutoff smaller than the molecular weight of the enzyme. This can be done at 4oC to slow down the reaction during the separation.

Which of the following is an example of a non contact force

Answers

Answer:

Gravity, Electrostatic force, Magnetic force

Explanation:

A non-contact force is a force that is applied to an object by another object without contact. Gravity, electrostatic force, and magnetic force all don't need two objects to be touching in order for them to work.

On the other hand, an example of a contact force is friction, because it can only occur if two objects are touching. If you want to tell the difference between a contact and non-contact force, just ask yourself if it can occur if the two objects are not touching. If it can occur while two objects aren't touching, it is non-contact, and if it can't, it is contact.

All the options given describe a force that involves contact except for the force exerted by magnets. Thus, the correct option is C.

Magnetic force is the force exerted by magnets. It can be described as the effect exerted on a charged particle due to the magnetic field of the other particle.

It is a consequence of the electromagnetic force, which is caused due to the movement of electrically charged particles.

Two objects that are oppositely charged will have a magnetic force of attraction, whereas two objects that have the same charge will have a magnetic force of repulsion.
