Describe step by step, with your own words, the process of replication of a double strand of DNA.

Answers

Answer 1

Answer:

replication. DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.

How often should observations be made in a simulation of natural selection??

Answers

Answer:

A minimum of 3 observations will produce reproducible results

Explanation:

Often, when simulations are carried out to observe for natural selection, it will be safe to conduct >3 observations to reduce the likelihood of errors. Errors could affect the reproducibility of the results which researchers will not want to compromise. The models ( for example the physical natural selection simulation or the virtual natural selection simulation methods) that are used provide for more observations to be made to ensure more accurate results and interpretations are obtained.

Think back about your experience in this lab using a dichotomous key. What might make it hard for someone to use a dichotomous key? Make a list of possible reasons.

Answers

Answer: why it is hard to use dichotomous key in the lab are;

If the organisms you want to use it for are similar.

If you can't see the little characteristics posses by the organisms you are using it for.

If all the pictures does not reveal all the important features of the organisms.

It is very difficult to use it to determine the anatomical structure.

Explanation:

Dichotomous key is an important method that is use in biology to identify organisms by separating or dividing the organisms into two groups. It is a tool created by scientists to help them identify organisms or objects. Once the organisms are group into two, more information is revealed more individually.

outline the digestion of fats ​

Answers

Answer:

In the small intestine , bile salts emulsify fats. They lower the surface tension of the fats , that is , they reduce the attractive forces between the fat molecules . This causes the fats to break into tiny fat droplets suspend in water , forming an emulsion . Note that this is just a physical break -up , but no chemical digestion of fat molecules has occurred . Emulsification increases the surface area to volume ratio of the fats , speeding up their digestion by lipase.

Emulsified fats are digested by lipase (pancreatic and intesɠintestinal lipases ) to fatty acids and glycerol . Thus the end - products of fat digestion are fatty acids and glycerol .

Which do you think is better for the environment: paper or plastic

Answers

Answer:

I think it is plastic

Explanation:

even though it take 400 years for a paper bag to decompose, people use more plastic.

Answer:

Paper is better for environment

Explanation:

Paper is because it decomposes much more quickly than plastic, and because of that it is less likely to be a source of danger and  will not pose a risk to wildlife. Paper is also more recyclable, while plastic can take between 400 and 1,000 years to decompose.

Where are metamorphic rocks likely to form?

Answers

Answer:

You would most likely find metamorphic rocks if you dug deep into the earth. This is because these types of rocks form in areas of extremely high heat and pressure.

Answer: deep in planets crust

Explanation:

Although metamorphic rocks typically form deep in the planet’s crust, they are often exposed on the surface of the Earth. This happens due to geologic uplift and the erosion of the rock and soil above them. At the surface, metamorphic rocks will be exposed to weathering processes and may break down into sediment.

Cancer cells continue to grow in the cultures uncontrollably allowing scientists to test multiple medications on the cancer cells. Specific treatments that are shown to fight the growth of cancer cells in the culture can be used on patients. Cultures are safer to use than injections of unneeded medications into patients.

Answers

Answer:

The statements are correct.

Explanation:  

Cell culture is a technique widely used in molecular biology where cell lines are grown in controlled conditions, thus allowing to make experiments and to test compounds that may result useful to treat diverse diseases, including cancer.  

Immortalized cell lines are characterized for their ability to proliferate indefinitely which are derived from oncogenic tissues. In cancer research, these lines are used as models to test different drugs and to study cellular mechanisms associated with cancer progression including, among others, proliferation, invasiveness, vascularization, etc. In addition, the mechanisms associated with the death of cancer cells such as, for instance, apoptosis, may also be studied by using immortalized lines.

Which scenario causes gene flow

Answers

Answer: Migration is one way that genes are transferred from one population to another.

Explanation:  Gene flow is caused by a significant change in the population of individuals due to the addition of other individuals whose alleles are slightly different from those of the existing individuals

Answer:

Introgression refers to gene flow from another taxon. While low levels of gene flow between species are not uncommon, it is a serious issue when an introduced invasive species hybridizes with a native species and overwhelms its genetic constitution (genetic swamping). This is a major threat in canids, ducks, fish and plants. For example, exotic rainbow trout introduced into the habitats of native cutthroat trout in the Western United States led to hybrid swarms that eventually overwhelmed the local species. Introgression is readily detected by molecular genetic and genomic methods.

What is the relationship between a codon and an anticondon

Answers

tRNAs bring their amino acids to the mRNA in a specific order. This order is determined by the attraction between a codon, a sequence of three nucleotides on the mRNA, and a complementary nucleotide triplet on the tRNA, called an anticodon. This anticodon also specifies the particular amino acid that the tRNA carries.

Answers

Answer:

Explanation:

In carbon cycle, carbon is just being recycled from one thing to other. For example, here we can see that green plants are part of carbon cycle because they go through photosynthesis, a process through with plants take in Carbon dioxide. The carbon is then used to make molecules such as carbohydrates and proteins, and are part of structural support to plant cells as well. Now when this organism (the organism could be an animal or plant) dies, the bacteria decomposes the organic matter (the dead body) and through respiration the carbon dioxide is released back into the environment.

Another way carbon recycles is that animals, plants, and microorganisms all respire (breathe out) CO2 thus carbon dioxide is added to the environment.

Answer:

Hi.. Ok lets start with animals.....Animals give out carbon dioxide during the breathing process and obtain oxygen.The carbon dioxide given out by the animals is obtained by green plants which use it on addition to chlorophyll water and light energy to make their own food.When animals die they decompose to form micro organisms...The micro organisms add nutrients to the soil thus promoting the growth of plants.I think it is the foodchain

Which type: Land breeze or sea breeze would most likely form on a warm, cloudless, summer day? How do you know? Explain

THXSSS PLEASE HELP AND HURRY

Answers

Answer:

Explanation:

Sea breeze is a breeze that comes from the ocean to the land. The breeze is usually more when the temperature difference between land and ocean is high especially when it is summer and hot afternoon.

When the temperature is hot both land and water are been heat up, the land begin to release heat and warm air will rise over the land. Water do not get heat up easily hence the air is cooler leading to high pressure on the ocean air then blows from here to the land.

Answer:

Sea breeze.

This is because sea breeze occur on hot summer days which is due to unequal heating on the land surface and sea surface

Explanation:

Land and Sea breezes are as a result of different rate of heating on land or sea surfaces along coastal areas.

Sea breeze occur in a warm, cloudless summer days because of the unequal heating of the land and water surfaces.

During the day, the land surface heat more that the water surface. The air that is above the land become warm and it is warmer than that on the sea surface but the warm air is lighter than cool air. The warm air above the land surface rise, and the cool air on the sea surface rises and replaced the land warm air . This is sea breeze

D) organisms are made up of large number of cells

The feature of cell theory that is best demonstrated in the image is organisms are made up of a large number of cells. Thus, the correct option for this question is D.

What is Cell theory?

The cell theory was proposed by two famous scientists. i.e. M.J. Schleiden and T. Schwann. There are three assumptions that fall under the cell theory.

All living organisms whether plants or animals are made up of cells.A cell is the smallest unit of all living organisms.It is the basic structural and functional unit of life.

Cell theory was further refined by German biologist Rudolf Virchow in 1855. According to him, all cells are arising from pre-existing cells.

According to the three assumptions given above, the one which is best demonstrated by the image is that Organisms are made up of a large number of cells.

Therefore, the correct option for this question is D.
