Location D
Answer:
location b is the answer
At location B in the diagram, the granite is likely to be formed. so, the correct option is (B).
What is Granite?
Granite is a coarse-grained intrusive igneous rock which is composed of quartz, alkali feldspar and plagioclase. It is formed from magma with a high content of silica and alkali metal oxides which cools slowly and solidifies underground.
It is a light-colored plutonic rock found throughout the continental crust, mainly in mountainous regions consisting of coarse grains of quartz, potassium feldspar and sodium feldspar. All these minerals make up more than 80% of the rock.
Granite is used in counter tops, floor tiles, paving stone, curbing, stair treads, building veneer, and cemetery monuments.
Thus, at location B in the diagram, the granite is likely to be formed. so, the correct option is (B).

Identify how Newton's third law of motion was responsible for the astronaut's return to the space station.
Answer:
sorry i cant understand clearly
Explanation:
i hope its help more
Answer: The equipment will "push back" on the astronaut with the same amount of force.
Explanation: Newton's third law of motion can be summed up as "For every action, there is an equal and opposite reaction." This means that when the astronaut applies force to push the object, that object will apply an equal amount of force to the astronaut.
The area of the cell that is associated with the production of ribosomes is the:
1. nucleolus
2. nucleus
3. nuclear pores
Answer:
Nucleolus
Explanation:
This is a more technical answer. The Nucleolus is located inside the nucleus and this is the location where the ribosomes are produced. They then leave through the nuclear pores to be sent out into the cell.
The area of the cell that is linked with production of ribosomes is nucleolus. The correct option is 1.
What is nucleolus?The nucleolus is a circular shape within the nucleus of cells that produces and assembles the cell's ribosomes. Ribosomal RNA genes are also transcribed in the nucleolus.
The nucleolus has the most visible realm in the nucleus of a eukaryotic cell, and its basic task is ribosomal RNA (rRNA) melding and ribosome biogenesis.
The nucleolus, as the site of ribosome biogenesis, is critical to cell metabolic activity.
It is made up of ribosomal DNA (rDNA), which is found in tandem arrays in nucleolus event coordinator regions.
The nucleolus synthesizes ribosomal subunits from proteins and ribosomal RNA, or rRNA.
It then starts sending the subunits to the rest of the cell, where they join together to form complete ribosomes.
Thus, the correct option is 1.

Which of the options below identify the genetic hiearchy in ascending order?
A. Chromosome, Cell, DNA, Gene and Nucleus
B. Gene, DNA, Chromosome, Nucleus and Cell
C. Cell, Nucleus, Chromosome, DNA and Gene
D. None of the above
Answer:
I hope this helps just to let you know this is what I searched just being honest :)
Explanation:
DNA
But your genes also mean that you probably look a bit like other members of your family. For example, have you been told that you have 'your mother's eyes' or 'your grandmother's nose'?
Genes influence what we look like on the outside and how we work on the inside. They contain the information our bodies need to make chemicals called proteins. Proteins form the structure of our bodies, as well playing an important role in the processes that keep us alive.
Genes are made of a chemical called DNA, which is short for 'deoxyribonucleic acid'. The DNA molecule is a double helix: that is, two long, thin strands twisted around each other like a spiral staircase.
27 DNA.gif
The DNA double helix showing base pairs
The sides are sugar and phosphate molecules. The rungs are pairs of chemicals called 'nitrogenous bases', or 'bases' for short.
There are four types of base: adenine (A), thymine (T), guanine (G) and cytosine (C). These bases link in a very specific way: A always pairs with T, and C always pairs with G.
The DNA molecule has two important properties.
It can make copies of itself. If you pull the two strands apart, each can be used to make the other one (and a new DNA molecule).
It can carry information. The order of the bases along a strand is a code - a code for making proteins.
Genes
A gene is a length of DNA that codes for a specific protein. So, for example, one gene will code for the protein insulin, which is important role in helping your body to control the amount of sugar in your blood.
Genes are the basic unit of genetics. Human beings have 20,000 to 25,000 genes. These genes account for only about 3 per cent of our DNA. The function of the remaining 97 per cent is still not clear, although scientists think it may have something to do with controlling the genes.
Chromosomes
If you took the DNA from all the cells in your body and lined it up, end to end, it would form a strand 6000 million miles long (but very, very thin)! To store this important material, DNA molecules are tightly packed around proteins called histones to make structures called chromosomes.
105-Gene-unwrapped.gif
The packaging of DNA into chromosomes
Human beings have 23 pairs of chromosomes in every cell, which makes 46 chromosomes in total. A photograph of a person's chromosomes, arranged according to size, is called a karyotype.
The sex chromosomes determine whether you are a boy (XY) or a girl (XX). The other chromosomes are called autosomes.
106-autosomes.gif
The karyotype of a male human being
The largest chromosome, chromosome 1, contains about 8000 genes. The smallest chromosome, chromosome 21, contains about 300 genes. (Chromosome 22 should be the smallest, but the scientists made a mistake when they first numbered them!).
The DNA that contains your genes is stored in your cells in a structure called the nucleus.

A negative feedback loop is a reaction that causes a decrease in function. Often, it causes the output of a system to be lessened; so, the feedback tends to stabilize the system. This can be referred to as homeostasis, as in biology, or equilibrium, as in mechanics.
What is baseline imbalance?This is simply known as a form of art that pertains to systematic error when producing an intervention groups in any clinical trial. In this type of imbalance, the groups differ in baseline traits due to the fact that the participants were selected or assigned.
There are different ways to balance a load. Why is the figure considered to be an example of a negative feedback system as opposed to a positive feedback system is that The figure shows the correction of an imbalance back to a baseline.
Therefore, A negative feedback loop is a reaction that causes a decrease in function. Often, it causes the output of a system to be lessened; so, the feedback tends to stabilize the system. This can be referred to as homeostasis, as in biology, or equilibrium, as in mechanics.

How have plants evolved?
Give at least 5 examples.
Answer:
Over time, plants had to evolve from living in water to living on land. In early plants, a waxy layer called a cuticle evolved to help seal water in the plant and prevent water loss. ... To allow the plant to retain water and exchange gases, small pores (holes) in the leaves called stomata also evolved (Figure below)
Explanation:
1 DNA evidence suggests that the first eukaryotes (green plants) evolved from prokaryotes (through endosymbiotic events) between 2500 and 1000 million years ago. ... Cyanobacteria have a close evolutionary relationship with eukaryotes. They have the same photosynthetic pigments as the chloroplasts of algae and land plants.
2Plants adapt their growth, including key steps in their life cycle such as germination and flowering, to take advantage of environmental conditions. ... All land plants evolved from an aquatic ancestor, and it was after colonisation of the land that the gibberellin mechanism evolved.
3 700 million years ago
The researchers found that land plants had evolved on Earth by about 700 million years ago and land fungi by about 1,300 million years ago — much earlier than previous estimates of around 480 million years ago, which were based on the earliest fossils of those organisms.
4 The earliest trees were tree ferns, horsetails and lycophytes, which grew in forests in the Carboniferous period. The first tree may have been Wattieza, fossils of which have been found in New York State in 2007 dating back to the Middle Devonian (about 385 million years ago).
5 Plants adapt to their environment from necessity. Plants may also adapt by growing lower and closer to the ground to shield themselves from wind and cold. Desert environments may have some of the following adaptations, these help the plant to conserve food, energy and water and still be able to reproduce effectively.

why CO2 still being produced for a few minutes after death?
Explanation:
As best as anyone can gauge, cell metabolism likely continues for roughly four to 10 minutes after death, depending on the ambient temperature around the body.
During this time period, oxygenated blood, which normally exchanges carbon dioxide with oxygen, is not circulating. Thus, cell respiration—which uses oxygen to make cellular energy while creating carbon dioxide as a by-product—creates carbon dioxide that is not transported out of the cell. This lowers the pH of the cell, resulting in an acidic intracellular environment. This acidic environment causes intracellular membranes to rupture—including those around the cell's lysosome, which contains enzymes for digesting everything from proteins to fats and nucleic acids. Once the membranes have burst, these enzymes are released and begin to digest the cell from the inside out. This process is known as autolysis (or self-digestion).
