Answer: The correct statements are 1 and 2:
1.Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant.
2.Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.
Explanation:
Pollination is the transfer of pollen grains from an anthers to a receptive stigma. In most species of flowering plants, external agents bring about pollination. Also, flowers have evolved special structures and mechanisms to ensure successful pollination.
There are two types of pollination
--> Self pollination: This takes place when mature pollen grains from the anther of a flower fall on the stigma of the same flower or that of another flower on the same plant. This type of pollination brings the male gametes and egg cells of the same plant together. The resultant offspring show very little genetic variation.
--> Cross pollination: This occurs when mature pollen grains of a flower are transferred to the stigma of a flower of another plant of the same or closely related species. This brings the male gametes and egg cells of two different parent plants together. Therefore, there is greater genetic variation among the offspring.
Two cells have surface area to volume ratios of 1:1 and 5:1. Which one has the ability to move nutrients in and expel wastes the best? Explain why
Besides for growth, what other reason would you want a new cell
to have the same exact DNA as the initial parent cell?
SELECT AN ANSWER
-You need to replace cells that are dead or
damaged.
-You want the new cell to have the
capability to live for an infinite amount of
time (avoid death).
-You want to avoid genetic mutations or
abnormalities.
-There is no other reason besides growth.
Answer:
You need to replace cells that are dead or
damaged.I think
In the 2016 movie, The Thinning, starring Logan Paul and Peyton List, a group of
teenagers must past a standardized test or be executed. The politicians who developed
this legislation did it because society was suffering from mass population and
legislatures wanted to thin' it out. Predict which is likely to occur as a result. Select all
that apply.
A. The population of children will Demonstrate more variety of intelligence
B. The population of children will demonstrate less variety in types of intellect
C. Intellect may be lost in areas other than academics
D. This will select for more intelligent children
Answer:
B. The population of children will demonstrate less variety in types of intellect
C. Intellect may be lost in areas other than academics
Explanation:
"thinning out" a population will most definitely result in less genetic variety! Children that aren't good at taking standardized tests (but smart at other areas of intellect) will be "executed". My last answer of the day! Hope this helps :)

For this assignment you will be researching the different types of fungi, and reporting on their usefulness. Choose 5 different fungi and report on the following: Name of fungi What are their major characteristics? Do they have one that separates them out from others? Where do they usually grow? Pros and Cons (are they toxic? Are they beneficial to plants? Nitrogen fixers?) Give two uses that they might have
Answer:
Brown rot fungi that produce hydrogen peroxide which attacks cellulose.
Soft rot fungi that produce an enzyme called cellulase which digests cellulose.
White rot fungi that produce enzymes capable of digesting lignin.
Phycomycetes (Algal fungi)
Ascomycetes (Sac fungi)
Basidiomycetes (Club fungi)
Deuteromycetes (imperfect fungi)
here are present different types of fungi. These fungi are classified based on their morphological structure of the mycelium spore formation, fruiting bodies and mode of life cycles. The fungi are divided into five phyla such as: Chytridiomycota, Zygomycota, Glomeromycota, Ascomycota, and Basidiomycota

How does the genetic code show a shared history among all organisms?
Answer:
All living organisms store genetic information using the same molecules — DNA and RNA. Written in the genetic code of these molecules is compelling evidence of the shared ancestry of all living things. ... Some mammalian genes have also been adopted by viruses and later passed onto other mammalian hosts.
Explanation:
A codon for certain amino acid is the same in every organism.

In the Osmosis Gizmo, the cell is placed in a very small chamber. Suppose a cell is placed in a large container of water with a very low solute concentration. What do you think would happen
Answer:
If a cell is placed in a large container of water with a very low solute concentration the solution will be hypotonic in nature. The water will enter inside the cell through semi-permeable membrane of cell. The cell will swell.

Which of the following best describes the cytoplasm in the cell?
a watery substance where cell processes take place
a hard substance that digests food molecules
a watery substance that keeps molecules from leaving the cell
a hard substance that keeps the cell rigid
Answer: A watery substance where cell processes take place.
Explanation: Process of elimination. The 2nd and last answer choices are both immediately wrong because cytoplasm is not a hard/solid substance. And the third answer choice is wrong because the cell membrane’s job is to prevent organelles from leaving the cell, not the cytoplasm. Therefore the answer is A, a watery substance where cell processes take place.
It is a jelly-like liquid that surrounds everything inside the cell.

Think back to the last lesson we covered. What is the difference between revolution and rotation of a planet?
Answer:
Revolution refers to movement around another object whereas rotation refers to the spinning of an object.
Explanation:
Revolution is defined as the movement of one object around another object whereas rotation is defined as the spinning of an object about its own axis. In revolution the object moves from one place to another around another object while on the other hand, in rotation the object does not moves from one place to another but rotates at one place.

What role do cell membranes and protocells play in the "RNA" world?
Answer:
reibosome
Explanation:
Reibosome is a large molecular complex that assmebles proteins.
Role of Cell membranes and Protocells:
Messenger RNA (mRNA) carries the protein blueprint from a cell's DNA to its ribosomes, which are the "machines" that drive protein synthesis. Transfer RNA (tRNA) then carries the appropriate amino acids into the ribosome for inclusion in the new protein.Protocells are thought to have facilitated the reproduction of RNA and therefore the exchange of genetic information at a time before the advent of DNA and proteins.Learn more:
