Which of the numbered labels is pointing to a transport organelle in the diagram?

Answers

Answer 1
Answer: Endoplasmic Reticulum

ER Golgi apparatus, because it packages proteins received from the ER cytoplasm 

The Golgi body are the ones that slightly alter, organize and prepare so-called parcels to be delivered for all the organelles in the cell. They receive these packages mainly in the rough endoplasmic reticulum. These packages that set out by Golgi body are macromolecules that used and synthesized by cells in many operations. If ER is absent then it would only mean that Golgi body would have no use other than simply lysosomes but these macromolecules plays a dynamic role in many organelles –nutrients, ATP and cell metabolism. It'll have a ripple effect if ER is absent in the cell.

Why is the demand for environmental scientists and specialists expected to increase?

Answers

The goal of environmental science is to demonstrate the importance of the interrelationships between the different physical and biological components of the biosphere and to develop a set of scientific concepts and concepts to directly assess the causes and possible relationships to crises. environmental shaking our societies.

Earth's environment is constantly changing, especially in recent years with the advent of industry, deforestation and increased pollution that has disrupted many systems at the level of the biosphere (physical and biological), so the need of environmental scientists so that it can predict future events and how to restore the biosphere system.

Which example represents a DISADVANTAGE of asexual reproduction? A) Genetic variety slowly causes hundreds of species of beetles to form from a single species. B) A single antibiotic is able to quickly and easily kill millions of genetically identical bacteria. C) Millions of bacteria are quickly produced by cell division, in one afternoon in a jug of milk that has been left on the counter. Eliminate D) Male anglerfish must live on larger females as parasitic mates, since they encounter other anglerfish so infrequently in the deep ocean.

Answers

Answer:

The correct answer would be an option B.

Asexual reproduction is a reproduction in which offspring are produced from a single parent.

It does not involve fusion of gametes and crossing over due to which the offspring contain identical genome as that of parents.

This reduces the genetic diversity in a population due to which all the organisms of a population are at equal risk of extinction under unfavorable conditions such as high temperature, antibiotics, change in pH of surrounding medium et cetera.

Thus, the disadvantage of asexual reproduction is the lack of genetic diversity due to which a single antibiotic is able to kill millions of genetically identical bacteria.

Once the dye had been applied to the shirt, all that remained was to ______ it.A. dry
B. freeze
C. rinse
D. soak

Answers

Answer: D. soak

A dye is a colored substance that has the affinity for the substrate on which it is applied. A dye is typically an organic compound, which is mixed with a suitable binder, to keep it in a liquid state. It is used to provide color to the cloths.

When the dye has been applied to the shirt, all that remained was to soak it because, the binder or solvent will be absorbed by the shirt by capillary action, and the dye will impart it's color.

Once the dye had been applied to the t-shirt, all that remained was to soak it. This happens when you do a dip dye and you need to soak the shirt after applying the first or initial coloring. You can also dip the dyed shifty for other colors. The answer would be letter D.

How can plant crops be modified so that they do not need to be sprayed with pesticides that are also harmful to humans like normal crops are?A. They can be given human DNA so that the pests will not want to eat them.
B. They can be given bacterial DNA to produce a toxin that only works on bugs and other pests.
C. They can be given DNA to allow them to resist harsh conditions.
D. They cannot be modified to be better than organic crops.

Answers

The correct option for the modification done that needs to be sprayed with pesticides is option (b) They can be given bacterial DNA to produce a toxin that only works on bugs and other pests.

Here, we deal with the concept of genetically engineered crops, also called "genetically modified organisms" i.e., GMOs. GMOs approach the specific genes from bacteria of other organisms that produce the required toxins that are harmful only to pests that are inserted into the DNA of crops.  

GMOs are examined by crops like Bt cotton or Bt corn. They are genetically modified genes from the bacterium Bacillus thuringiensis (Bt), which are produced by the toxic proteins of certain insects. The use of genetically modified organisms is a complex issue related to the potential health effects, environmental impact, regulatory oversight, and many more.

All of the following are positive aspects of PACs EXCEPT?A. Members of PACs have access to candidates and parties.

B. PACs allow their members to support a range of candidates with a single contribution.

C. Candidates receive contributions from so many PACs that the effect of any single PAC is diluted.

D. PACs allow organizations to form a close connection to the legislators they support.

Answers

The correct answer is option C, Candidates receive contributions from so many PACs that the effect of any single PAC is diluted.

Reason -

Different parties that contribute to a certain candidate assumes to at least have a recognition to their contribution but since there are several donors (big or small), usually the donors with small amount of donation get neglected and the effect of their contribution is felt diluted. This seems to generate a negative aspiration in the donor.

I think the answer is C 

Why does the oxidation of organic compounds by molecular oxygen to produce CO₂ and water release free energy? A) The covalent bonds in organic molecules and molecular oxygen have more kinetic energy than the covalent bonds in water and carbon dioxide.
B) Electrons are being moved from atoms that have a lower affinity for electrons (such as
C) to atoms with a higher affinity for electrons (such as O).
C) The oxidation of organic compounds can be used to make ATP.
D) The electrons have a higher potential energy when associated with water and CO₂ than they do in organic compounds.
E) The covalent bond in O₂ is unstable and easily broken by electrons from organic molecules.

Answers

The oxidation of organic compounds by molecular oxygen to produce CO2 and water releases free energy because electrons are being moved from atoms that have a lower affinity for electrons.
