A. overtime racoons learn to get food from garbage cans.
B. over time a person increases muscle mass with exercise
C. overtime honeysuckle flowers developed a sweet smell to attract pollinators
D. overtime corn plants are bred to make larger corn cobs and kernels
Answers
Over time corn plants are bred to make larger corn cobs and kernels have occurred as a result of natural selection. Hence, option D is correct.
What is natural selection?The process through which populations of living things adapt and change is known as natural selection. A population's members are naturally varied, which means that they are all distinctive in some ways. This variety indicates that some people have characteristics that are more environment-appropriate than others.
The development of giraffes' long necks is a prime illustration of natural selection in action. Animals with necks of average length, like deer or antelope, were the ancestors of current giraffes.
Over time corn plants are bred to make larger corn cobs and kernels have occurred as a result of natural selection. Hence, option D is correct.

Answer:
How Do Cows Reproduce?
12 to 14 months is the age of puberty in a cow, but early maturing breeds do reach puberty by the time they are around 7 to 9 months of age. Cattle producers are working towards using science to bring that age down so that milk and meat producers can start using their cattle at a younger age. Usually, it's best to wait until they are at least 15 months of age before breeding cattle. This is so that their bodies have fully matured before trying to get them to reproduce. Even with the early maturing breeds you should wait around 13 to 15 months of age before you can breed them. The Estrous Cycle of Cattle averages a 21-day period. The length of ovulation varies partly depending on the species. The mean time of ovulation for dairy cows is 15 ± 2.6 hours. But the ovulation time does vary greatly, here are some other examples: Short- horn, 12.69 ± 1.15 hours; Angus, 13.93 ± 1.68 hours; and Hereford, 13.5 ±.87 hours. (www.sciencedirect.com/science/article/pii/S0022030241953912) A cow's gestation period (how long after insemination the mother is pregnant with the calf) is approximately nine months. But if your cow has calved before, there's a good chance she'll give birth after the same number of days as before. Some things you should consider when breeding cattle are as follows:
Safety- Your safety is more important than the animals, so it is smart to learn good safety measures when breeding such a large animal.
Fertility- You should get the IBR vaccine for your cows because IBR can cause the unborn calves to die. This situation is also known as an IBR abortion. Appropriate management of the bull is also an important factor when considering infertility. For example, you must have an appropriate bull to cow ratio for your farm and pastures.
Mating or insemination? - many farmers take the less natural rout of artificial insemination to grow there heard because they do not have to have a prized bull to have their cow breed with one. It can save farmers money to use artificial insemination, but it also flattens out the gene pool because lots of people are using the same animals so there’s less diversity. There are pro’s and con’s to both sides so make sure you do your research before deciding what method to take for breeding.
Breeding plan- Setting up a breeding program involves setting a breeding goal, making the selection of parents, and then carrying out the mating or artificial insemination. Your breeding plan should be specific to you and your farm.

a. Food must be digested and combined with carbon dioxide
b. Food must be digested and combined with oxygen
C. Food must be eliminated from the body
d. None of the above
Answers
The energy from the food is accessed by the digestion of food, in the presence of oxygen. Thus, option B is correct.
What is digestion?Digestion is the process of breaking down of food into smaller particles. The digestion of food is a chemical process that releases energy, and results in the other body processes.
The chemical reaction for the breakdown of food is processed with the availability of the oxygen for the formation of energy.
Thus, the metabolism process is accomplished with the digestion of food after combining it with oxygen. Thus, option B is correct.

Why is protein synthesis important when we talk about genetic variation?
Answers
Answer:
Protein synthesis is the process all cells use to make proteins, which are responsible for all cell structure and function. In transcription, DNA is copied to mRNA, which is used as a template for the instructions to make protein. In the second step, translation, the mRNA is read by a ribosome. The key to a protein molecule is how the amino acids are linked. The sequence of amino acids in a protein is a type of code that specifies the protein and distinguishes one protein from another. A genetic code in the DNA determines this amino acid code.

Answers
Answer: V(t)=5000(9/10)^t
Explanation:
If the car loses 1/10 of its value each year, that means 9/10 of the value remains each year.
So each year, the car's value is multiplied by a factor of 9/10 or 0.9
If we start with the initial value, $5000 and keep multiplying by 9/10 his function gives us the car's value t years from now:

It's a little difficult to see the difference between the finch 1 and finch 2 population lines, but their trends should match those of the food. This answer is assuming the finch 1 population aligns with the seeds line and the finch two population lines up with the fruit line: The finch 1 population has a beak adapted to eating seeds and the finch 2 population has a beak better adapted to eating fruit
Explanation:
Since we are given data for both the food source and the finch population, the answer will most likely reflect that. Therefore eliminating choices A (disease) and C (feathers). Again, this answer is assuming the finch 1 population aligns with the seeds line and the finch two population lines up with the fruit line. The lines for the finch population will match with the availability of food, so less seeds mean less finch 1 and when the amount of seeds rise up you can see the population of finch 1 also rises.

acidification is the consequence of a collection of greenhouse gases in the ocean.
D. Climate change is caused by increased solar activity, whereas ocean acidification is the consequence
of warming of the oceans.
E. Climate change is caused solely by the ozone hole because the hole lets in more radiation, whereas
ocean acidification is the consequence of accumulation of methane in the ocean sediments.
Answers
Answer:
Explanation:
A because Climate Change and Ocean Acidification Impacts on Marine Ecosystems. ... Acidification harms shell-forming plants and animals including surface and deep-water corals, many plankton, pteropods (marine snails), mollusks (clams, oysters), and lobsters.
While the term “ocean acidification” refers to the overall alteration in ocean chemistry caused by atmospheric carbon dioxide inputs, “coastal acidification” refers to a different mechanism by which coastal chemistry can change. Thus, option A is correct.
What ocean acidification different from climate change?The average pH of the ocean is 8.1 right now, making it basic (or alkaline), but when more CO2 is absorbed, the pH decreases and the ocean becomes more acidic.
Because of human activity, atmospheric carbon dioxide concentrations are rising, which causes more carbon dioxide to evaporate and enter the ocean.
Due to its extensive effects, ocean acidification is consequently the global warming's evil twin. In actuality, the disruption of the natural carbon cycle, which is the cause of both processes, is the same issue.
Therefore, This describes how the atmosphere, land plants, and oceans constantly exchange carbon.
