Pretty easy question (s) but I am not good at explaining things so I need help
There is 5 different scenarios. Describe how these scenarios happen.
I'm guessing the rocket scenario is the first one and the asteroid one is the last. That being said...
1) The fuel in the rocket provides it with the energy it needs to propel itself into space. The rocket throttles at the bottom, allow it to break free from the earth's gravity by pushing against the earth's greater mass.
2) If you are inside of the bus, in a fixed spot not moving, and the bus is moving. That means you are moving in the same direction as the bus. If it stops, you're still moving at the speed that it was once originally moving at. Obviously, since you weigh less than the bus you are going to fly forwards.
3) There is no gravity or friction in space, so items won't slow down no matter what. Even if an object such as a meteor is flung into space with the tiniest bit of force it will keep flying through space at a consistent speed, since there's nothing to slow it down... unless it hits something else.
4) Looking back at the previous answer, the asteroid is flying through space at a consistent speed (which is really fast). Suddenly it comes in close range to the moon which is bigger in size, and thus has a stronger gravitational pull, and pulls the asteroid into it's field.
Imagine researchers following up on seeley's study brought some flat periwinkles appledore island into the lab to test for heritability. What results could they observe that would support the hypothesis that shell thickness is heritable in these snails?
Answer:
If thick-shelled snails have thick-shelled offspring and thin-shelled snails have thin-shelled offspring then this is good evidence that shell thickness is heritable.
Explanation:
Inheritance is a natural mechanism by which genetic information contained in the DNA sequence is passed from parents to offspring. Moreover, heritability is a measure of the genetic influence on the variation in a particular phenotypic trait (e.g., height, eye color, etc.) between individuals in a population. The values of heritability for a particular phenotypic trait range from zero (when all variation in a population comes from environmental factors and therefore is not heritable) to one (when all variation in a population comes from genetic factors and therefore is heritable). For example, in this case, if parental snails always have offspring with the same phenotype for the trait ‘shell thickness’, it would indicate that the heritability for this trait is equal to one, thereby evidencing that all of the variability for the trait 'shell thickness' comes from genetic differences.

If you wish to use RNAi to reduce the expression of a gene in an organism. What would you inject into the organism
Answer:
double-stranded RNA (dsRNA) homologous to the gene of interest
Explanation:
RNA interference (RNAi) is a naturally occurring mechanism used by eukaryotic cells to suppress gene expression through regulatory non-coding RNAs (e.g., small interfering RNAs, siRNAs) that are complementary to the target gene of interest. These non-coding RNAs can bind to target messenger RNAs (mRNAs) in the cytoplasm in order to trigger mRNA degradation and/or block translation. The RNAi mechanism is widely used in molecular biology laboratories in order to inhibit the expression of target genes and thus understand gene function. The RNAi mechanism can be induced by transfecting into cells long double-stranded RNA (dsRNA) molecules that are complementary to the target mRNA sequence to be degraded. RNAi is initiated by the enzyme Dicer that cleaves dsRNAs into siRNAs (19 to 25 nucleotides), which are then incorporated into an RNA-induced silencing complex (RISC) in order to suppress gene expression at the post-transcriptional level (i.e., the mRNA is degraded after transcription).
In order to use RNA interference (RNAi) to reduce the expression of a gene in an organism, you should inject a double-stranded RNA (dsRNA) hom-ologous to the gene into the organism.
Gene expression can be defined as the transcription of a gene into a messenger ribonucleic acid (mRNA), followed by its subsequent translation into proteins. Thus, gene expression is typically controlled on two (2) main levels and these are:
TranscriptionTranslationRNA interference (RNAi) is also referred to as post-transcriptional gene silencing (PTGS) and it can be defined as a biological process in which the expression of a gene in an organism with respect to in which RNA molecules are sequentially reduced (suppressed) by double-stranded RNA (dsRNA), through transcriptional or translational repression.
This ultimately implies that, you should inject a double-stranded RNA (dsRNA) hom-ologous to the gene into the organism, if you wish to use RNA interference (RNAi) to reduce the expression of a gene in an organism.

3. While walking in the forest floor, you found an organism that has the following characteristics: had the consistency and appearance of a sponge, the tips were partially covered with a limy and foul-smelling substance whose odor attracts flies that disseminate its spores. How would you classify this organism? In what kingdom would you place this organism? What are your reasons?
Answer:
What are stinkhorns? Stinkhorns are mushrooms that are found from the tropics to more temperate regions such as Wisconsin. They can suddenly appear in mulch, lawns, and areas with bare soil. These visually-shocking fungi get their common name from their characteristic, unpleasant odor. Although they are often unwanted additions to home gardens, stinkhorns do not cause plant disease. Because stinkhorns can grow on dead organic material, they actually are beneficial in that they contribute to the recycling of plant debris into nutrients that improve soil fertility and can be used by garden plants.
What do stinkhorns look like? Stinkhorns grow into various shapes, but they are bestknown for looking like horns or penises. A few species grow several appendages, resulting in an octopus-like appearance. Some species have a veil attached below the cap that resembles a lacey skirt flowing from the mushroom’s hollow stalk. Stinkhorns can range in color from white, beige, and olive to bright orange or red with black accents. The tips of mature stinkhorns are usually coated in a spore-containing slime. Gardeners often discover immature stinkhorns as they dig in the soil. The immature forms appear as whitish to pink or purple, egg-shaped masses. Stinkhorns develop rapidly sometimes growing up to four to six inches per hour, and can generate enough force to break through asphalt.
Where do stinkhorns come from? Stinkhorns are often first introduced into a garden in organic materials (e.g., soils and mulches) that contain microscopic hyphae (i.e., fungal threads) of stinkhorn fungi. Once stinkhorns mature, they produce a pungent, off-putting odor that is reminiscent of rotting flesh or dung. This smell may disgust people, but it attracts insects, particularly flies. Flies and other insects eat the slimy material at the tips of stinkhorns and carry spores in this slime to new locations as they move around in the environment. In many ways, this process is comparable to the distribution of pollen by bees (but of course without the more appealing scents associated with most flowers).

Group of answer choices
Soil washes away more easily.
Plants are able to grow more easily.
Fewer plants are available for animals.
Nutrients that help plants grow can wash away.
Answer:
Plants are able to grow more easily.
Explanation:
Due to the loss of trees, the roots keep the surrounding soil hydrated allowing plants and trees to grow, without trees the dirt slowly will become very dry and cracked, causing the dirt to become dehydrated, which makes plants die because the water will go straight down low where plants cant reach.
Genetic recombination plays a role in both maintenance and diversity within an organism. Explain how this balance is achieved and the underlying mechanism of recombination that are involved.
Answer:
Crossing-over between homologous chromosomes (prophase 1), the random lining of homologous chromosomes (metaphase 1), and random fertilization are the mechanisms involved in genetic variation.
Explanation:
Crossing-over between homologous chromosomes (prophase 1), the random lining of homologous chromosomes (metaphase 1), and random fertilization are the mechanisms involved in genetic variation.
The Crossing-over events occur between two homologous chromosomes in the equatorial plane and make the daughter cells genetically different from the original one. The Chiasma is the position where two homologous chromatids interchange genetic information, giving a place for new genetic material or information to be provided to descendants. After crossing over, homologous chromosomes get separated again.
On the equatorial plane, homologous paired together, randomly aline with their kinetochores facing opposite poles. The random arrangement of tetrads is different in every cell going through the meiosis process. There is no equal alinement between two cells. When tetrads aline in the equatorial plane, there is no predetermined order for each of the homologous chromosomes of each tetrad to face one of the poles and then migrate to it while separating. Chromosomes of the homologous pair arrange to face any of the poles to migrate forward to it. Each of the chromosomes has two possibilities for orientation at the plane. When the new haploid cells are formed, the number of variations in each cell is also different and depends on the chromosomes that form that cell. The order in the equatorial plane is what introduces variation into the gametes, being almost impossible for two gametes to have the same genetic charge.
Independent assortment occurs when the alleles from two or more different genes distribute in gametes independently from each other. In other words, a gamete receives an allele from a gene that does not depend on nor influence the allele of another gene in the same gamete. This can only be applied to independent genes. An organism gets only one of the members of the chromatids pair of each parent.
