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.

Matter is anything that has mass and takes up space. It includes molecules, atoms, fundamental particles, and any substance that these particles make up. Matter can change form through physical and chemical changes, but through any of these changes matter is conserved.
In other words, matter doesn't change into a different substance in a physical change. ... Changes of state—for example, from solid to liquid or from liquid to gas—are also physical changes. Some of the processes that cause physical changes include cutting, bending, dissolving, freezing, boiling, and melting.

Question 1 of 10
In which sealed container would the organisms be able to continuously cycle
O2 and CO2 gases?
A. A terrarium with a plant and a snail
B. An aquarium with fish and plastic plants
C. A terrarium with tadpoles and a pool of water
D. An aquarium with rocks and snails
Answer:Option A
Explanation: The snail breaths in the O2 which will then exhale CO2, therefore the plant will take that and process the CO2 back into O2.
The organisms would be able to continuously cycle O2 and CO2 gases in a sealed container of a terrarium with a plant and a snail. Thus, the correct option is A.
How do O2 and CO2 cycle in the environment?The carbon dioxide is utilized by the photosynthetic plants in order to synthesize their own food through the process of photosynthesis. They form oxygen as a product which is then utilized by other living organisms for respiration and exhaling carbon dioxide in the surroundings.
A terrarium with a plant and a snail follows the same principle of exchanging oxygen and carbon exchange within the sealed container environment which is described above.
An aquarium with fish and plastic plants does not exchange carbon dioxide and oxygen because plastic plants are not able to perform photosynthesis.
Therefore, the organisms would be able to continuously cycle O2 and CO2 gases in a sealed container of a terrarium with a plant and a snail. Thus, the correct option is A.

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.
What role do DNA and genes play in the inheritance of traits?
Answer:
Genes provide instructions for making proteins, and proteins determine the structure and function of each cell in the body, it follows that Genes are responsible for all the characteristics you inhert
5. You cross one black (Bb) mouse with one brown (bb) mouse. Complete the Punnett square to find the expected ratio of black to brown mice pups. All six mice pups in the litter have brown fur. Explain this result.
I think all the mice had brown fur due to epistasis
Explanation:
The expected results would be 50% black and 50% brown and the ratio could be 2:2. But, if epistasis occurred and the brown fur gene overshadowed the black fur gene, then all the offspring could have brown fur.
The Punnett square to find the expected ratio of black to brown mice pups is to be considered when all the mice had brown fur because to epistasis.
Completion of the Punnett square:The expected result should be 50% black and 50% brown and the ratio should be considered as the 2:2.
In the case when epistasis should be arisen and brown fur gene should be overshadowed the black.
Hence, the same should be considered.

A. Describe the role of the promoter in eukaryotic gene expression. Explain how a negative regulatory molecule could inhibit transcription at the promoter.
B. Identify TWO events that occur during RNA processing. Explain how RNA splicing increases the variation of mRNA molecules.
C. Describe the role of miRNA in gene expression.
Answer:
Explanation:
A. The role of promoter in eukariotic gene expression is It is to bind transcription factors that regulate transcription initiation. This molecule is so important because control the binding of RNA polymerase to DNA. The promoter region may be short or very long; the longer the promoter is, the more protein binding space is available. A negative regulatory molecule has the possibilty to inhibit transcription at the promoter because these molecules block the binding of RNA polymerase to the promoter region, thus not allowing the initiation of transcription, in some particular cases, the negative regulator binds to the lac repressor and will bind to the promoter in the same site where RNA polymerase would bind to.
B. Two process that occur during RNA processing are RNA splicing and 5′ capping, 3′. RNA splicing is a procces known for removing the introns from the pre-RNA and stuck back together the restant parts, exons. This process has as a goal form a mature mRNA that does not contain the intron sequences. RNA splicing has effect on variation of mRNA molecules because through a process called alternative splicing more than one mRNA can be made from the same gene.
C. Even though they are not quite the same thing miRNA and negative regulatory molecules have the same role, which is inhibit the translation and silence genes. They regulate gene expression by binding to the 3'-UTR of their target mRNAs and destabilizing the mRNA and translational silencing, repressing protein production. Even so, under specific circumstances, miRNA can activate translation or regulate transcription.

1. In cattle (R) is incompletely dominant over white (W) hides. Roan is the name of the color that results from the incomplete dominance. What are the
possible results if a white male is crossed with a roan female? Make sure to give genotypic AND phenotypic ratios in your answer.
When white male (WW) is crossed with a roan female (RW), 2 roan (RW, RW): 2 white (WW, WW) offspring are produced.
What is genotype?"The internal makeup of genes is called genotype."The alternative form of gene is called allele.The allele that is expressed in the generation is called dominant allele and the allele whose expression is masked and is only expressed if both of its copy is present is called recessive allele.What is phenotype?"The expressed characters are called phenotype."What is incomplete dominance?"In this condition both alleles of a gene are expressed, which will result in an intermediate or different phenotype."Here, it is given that red (R) is incompletely dominant over white (W) hides, which means that when RR is crossed with WW it produces RW (roan color). So, when RW (roan color) is crossed with WW (white color) it produces RW, RW, WW and WW.Hence, 2 roan (RW, RW) : 2 white (WW, WW) offspring are produced.
