0)“If Jupiter was not there, there could be more terrestrial planets”. Explain how
what would happen if there was no Jupiter?
There would be minor changes in the planets' orbits about the Sun, but very little else. However, Jupiter does a great job of shepherding and absorbing small objects in the Solar System. With Jupiter gone, the main effect on Earth would be an increase in the rate of impacts from asteroids and other space flotsam.

A population of plants growing in a field is examined over a period of years. The plants have either white or yellow flowers.
What best explains the observations?
A. White flowers increase the plant's fitness, so the population is under directional selection.
B.Yellow flowers increase the plant's fitness, so the population is under directional selection.
C.Yellow flowers increase the plant's fitness, so the population is under disruptive selection.
D.White flowers increase the plant's fitness, so the population is under disruptive selection.
Thebest explanation for the observation is that white flowers increase the plant's fitness, so the population is under directional selection.
What is genetic variation?Genetic variation refers to the differences that exists in the genes of organisms of the same species or different species.
The gene for flower color in the plants has two alleles for yellow and white flower color.
Over time, the proportion plants with white-colored flower increased while that of yellow decreased.
Therefore, the best explanation for the observation is that white flowers increase the plant's fitness, so the population is under directional selection.

Select all that apply.
The risk of unknown side effects if we allow it.
The cost of human suffering if we don’t allow it.
The effects on future generations if we allow it.
The risk that genes will not end up in future generations if we allow it.
The ethical concerns related to editing the genes of germline cells include the risk of unknown side effects and effects on future generations.
What is gene editing?Gene editing refers to the genetic engineering technologies aimed at modifying the content of genes.
Germinal gene editing assumes the edition of the germinal line and therefore it affects the gene content of future generations.
In conclusion, the ethical concerns related to editing the genes of germline cells include the risk of unknown side effects and effects on future generations.

Cytokinesis is when the cell
separates into two identical
daughter cells. Cytokinesis is
which phase of cell division?
Answer:
D.) Last
Explanation:
If cytokinesis is when the cell separates into two identical daughter cells, this means that DNA replication and mitosis must have already occurred. The duplication of the parent cell's DNA and organelles is what makes the daughter cells identical. These processes must occur before the cell literally divides.

how does one type of rock is transformed to another type of rock?
Answer:
This can happen through the rock cycle. But there are 3 processes which are crystalization, erosion and sedimentation, and metamorphism.
Explanation:
There are several types of rocks, but only one large furnace in which parts of a single large rock are cooked and changed into the various types of rocks. Our planet is a massive rock and a massive furnace. All rocks are divided into three categories, or classes. They're classified as sedimentary, metamorphic, or igneous, with variances in how they're generated.
I'll show you a schematic of the Rock Cycle instead of a detailed answer. It shows how one type of rock may be converted (metamorphic) into another under certain conditions. Just bear in mind that some types of rocks, such as sedimentary rocks, may form in a matter of hours, while others, such as metamorphic rocks, take millions of years to create.

You’ve found some fossil bones while digging in your backyard. could they be dinosaur bones? using carbon dating, you determine that 3% of the original radioactive carbon-14 is still radioactive. (the rest has decayed into nitrogen-14.) how many half-life cycles has it gone through? approximately half-life cycles.
Since 3% of the original radioactive carbon-14 is still radioactive, the carbon-14 radioisotope has undergone five half-lives.
What is Half-Life?Half-life of a substance is the time it takes for half the original amount of the substance to decay.
Radioactive elements decay spontaneously according to their half-lives.
Since 3% of the original radioactive carbon-14 is still radioactive, the number of half-lives undergone is determined as follows:
After one Half-Life, 50% remains
After two half-lives, 25% remains
After three half-lives, 12.5% remains
After four half-lives, 6. 25% remains
After five half-lives, 3.125 % remains.
Therefore, the carbon-14 radioisotope has undergone five half-lives.

A bird-watcher sees a small yellow bird in a tree. explain to the bird-watcher how he can use a dichotomous key to identify the bird. assume he does not know anything about dichotomous keys. then, write two steps of a dichotomous key that would be helpful for the bird-watcher.(2 points)
At each step, a dichotomous key divides proof of identity into two mutually preferential options. To use the key, the scientist begins at the top and determines which of the two options applies to their organism. The key directs them to a new question based on their response.
What is dichotomous key?This key aids in the identification of organisms by directing the attention to identify the organisms.
The steps to use a dichotomous key are:
Organize the characteristic of the organism.Divide the specimen.Draw a dichotomous key either text-based or graphical.Check out for the unknown organism.Thus, these are the steps that the bird-watcher can use for identifying the bird.

What is the amount of heat energy needed to raise the temperature of
200 g of water from 10°C to 40°C? (water = 4.18 J/g°C)
Answer:
25116 J
Explanation:
Q = m × c × ΔT
c = 4.186 J/g°C
M=200 g
So,
Q = 200 × 4.186 × (40-10)
=200 × 4.186 × 30
=25116 J

13. What happens when a protein is deNtured?
Denaturation involves the breaking of many of the weak linkages, or bonds (e.g., hydrogen bonds), within a protein molecule that are responsible for the highly ordered structure of the protein in its natural (native) state. Denatured proteins have a looser, more random structure; most are insoluble.

Explanation:
if destructive interference occurs between a wave with a six foot trough and a three foot crest, what factors will determine the height of the resulting wave?
Destructive interference formed when the two meeting waves are out of phase and in some cases, the two wavers maxima are 180 degrees out of phase. The height of waves is determined by the wind speed, how the long wind blows, and crucially the fetch.
The longer the duration of wave, the larger will be the wave heights. The longer the fetch, the large will be wave heights.
What is interference?Some waves jump to cross over or meet with each other. When they do, the reaction between the waves is called interference.
If at a given location, both interfering waves are supersede in the same direction (both up or both down) then it is known as constructive interference.
