Answer:
That sample, nicknamed the Genesis Rock, sample number 15415, was an anorthosite, a piece of the moon’s primordial crust. Geologists, hoping to learn more about the moon and its origins, selected the Hadley-Apennines landing site for precisely this reason. While not the oldest lunar sample brought back from the moon, geologists at the Manned Spacecraft Center (now known as the Johnson Space Center) later concluded that this rock was about 4 billion years old

genetic possibilities from independent assortment of its single gamete.
An organism with five pairs of chromosomes can have
A diploid organism with five pairs of chromosomes can have 2^5 = 32 possible gamete combinations. It is due to random assortment.
Gamete combinations and random assortmentA gamete is a germinal cell, which contains only one set of chromosomes in diploid organisms.
Random assortment refers to the random separation of homo-logous chromosomes during meiosis.
The random assortment is known to increase genetic variation by increasing the number of possible genetic combinations.

Answer:
The water is transported to the top most leaves (and rest of its parts) of a tall tree by three actions:
1) root pressure (osmosis)
2) capillary action (adhesion)
3) evapotranspiration (cohesion)
Explanation:
The trees contain a series of interconnected tissues (xylem and phloem) that act as network for transport of water and nutrients throughout the tree. The root pressure and capillary action push the water, while the transpiration from the leaves pull the water. The root pressure is generated by osmotic movement of water from soil to the root tissues. The capillary action is caused due to adhesion of water molecules. However, root pressure and capillarity is thought to support only few meters of water column. The rest of the water transport (esp. in tall trees) is attributed to negative pressure generated by evaporation of water from leaves. This negative pressure creates a vacuum and pulls the water from the roots.

Rachel Carson wrote in Silent Spring, "The chemical war is never won, and all life is caught in the crossfire." Respond
Answer:
Yes.
Explanation:
Yes, the statement is right because in chemical war, great damage occurs to all living organisms that has a bad effect on our environment. These chemicals are very dangerous so its usage in the war has long term effects on the environment and the organisms that live in it. Both the opponents receive great damage from this chemical war and the destruction of the natural beauty of the place vanished where this war occurs so this vanished of beauty and organisms is the defeat of both the opponents that fought this war.

How can a gene that contains introns be made shorter for genetic engineering purposes? What does it use and how does it use it?
Answer:
reverse transcriptase to reconstruct the gene from its mRNA
Explanation:
Genetic engineering may be defined as the process of using the recombinant DNA (rDNA) technology in order to alter the genetic makeup of the organism. It is also called as the genetic modifications. It uses the science of biotechnology to modify and manipulate the genes of an organism.
A gene containing introns can be made shorter and still remain functional for the genetic engineering purposes by using the reverse transcriptase for reconstructing the gene from the mRNA.
It uses the reverse transcriptase of the mRNA.

When scientists examine the gases ejected during a volcanic eruption, the majority of the gas is water vapor. How does the process of subduction provide a water source for volcanic gases?
Answer: Volcanic gases are gases given off by active (or, at times, by dormant) volcanoes. These include gases trapped in cavities (vesicles) in volcanic rocks, dissolved or dissociated gases in magma and lava, or gases emanating from lava, from volcanic craters or vents.
Answer:
When an oceanic crust and a continental crust converge, the denser oceanic crust subducts under the continental crust. During this process, seawater is added to the volcano’s magma. Much of this water is heated and ejected during an eruption as water vapor.

What 3 things make up a nucleotide (unit of DNA/RNA)?
how does respiration take place in insects?
Answer:
please give me brainlist and follow
Explanation:
Instead of lungs, insects breathe with a network of tiny tubes called tracheae. Air enters the tubes through a row of holes along an insect's abdomen. The air then diffuses down the blind-ended tracheae. Since the biggest bugs have the longest tracheae, they should need the most oxygen to be able to breathe.
