What are some ways you think scientists can affect or utilize the genes of organisms?
Answer:
I'm not quite sure what your looking for
Explanation: scientists can take the genes of one successful crop, animal, etc, and insert that gene into future things so all offspring will be successful. This is called genetically modifying. Another thing scientists can utilize genes for is cloning. There have been ideals of the perfect human for many years and now scientists are trying to alter these genes to have perfect offspring according to your standards.

Explanation:
The principle of superposition states that the oldest sedimentary rock units are at the bottom, and the youngest are at the top. Based on this, layer C is oldest, followed by B and A. So the full sequence of events is as follows: Layer C formed.
All compounds that have been found to be mutagenic in the Ames test are also carcinogenic. View Available Hint(s) All compounds that have been found to be mutagenic in the Ames test are also carcinogenic. True False Submit Part B Why are liver extracts used in the Ames test? View Available Hint(s) Why are liver extracts used in the Ames test? A liver extract is necessary for the bacteria to produce histidine revertants. Liver enzymes activate the bacterial enzymes. Liver enzymes may activate some innocuous compounds, making them mutagenic. The bacteria require the nutrients present in the liver extract for growth.
Answer:
Part A: False
Part B: Liver enzymes may activate some innocuous compounds, making them mutagenic
Explanation:
The Ames test, also known as Salmonella typhimurium reverse mutation assay, is a bacterial short-term technique used to identify if a particular chemical compound may cause mutations in target cells. It has been shown that there exists a positive correlation between carcinogenicity and mutagenicity in the Ames test, but this correlation is not absolute. In the Ames test, a rat liver homogenate (containing liver enzymes) can be added in order to identify substances that are not mutagenic themselves but are metabolized in order to form a mutagen (e.g., benzopyrene).

Will give Brainliest within five minutes of answer - Why do we want to explore Mars more than the other planets/moons even though it is not currently habitable (with its temperatures, atmosphere, etc.)? How can it be habitable?
Answer:
After the Earth, Mars is the most habitable planet in our solar system due to several reasons:
Its soil contains water to extract
It isn’t too cold or too hot
There is enough sunlight to use solar panels
Gravity on Mars is 38% that of our Earth's, which is believed by many to be sufficient for the human body to adapt to
It has an atmosphere (albeit a thin one) that offers protection from cosmic and the Sun's radiation
The day/night rhythm is very similar to ours here on Earth: a Mars day is 24 hours, 39 minutes and 35 seconds
The only other two celestial bodies in orbits near the Earth are our Moon and Venus. There are far fewer vital resources on the Moon, and a Moon day takes a month. It also does not have an atmosphere to form a barrier against radiation. Venus is a veritable purgatory. The average temperature is over 400 degrees, the barometric pressure is that of 900 meters underwater on Earth, and the cherry on top comes in the form of occasional bouts of acid rain. It also has nights that last for 120 days. Humans cannot live on Mars without the help of technology, but compared to Venus it's paradise!
Additional info:
Mars is an obvious target for exploration because it is close by in our Solar System, but there are many more reasons to explore the Red Planet. The scientific reasons for going to Mars can be summarised by the search for life, understanding the surface and the planet’s evolution, and preparing for future human exploration.
Searching for life on Mars
Understanding whether life existed elsewhere in the Universe beyond Earth is a fundamental question of humankind. Mars is an excellent place to investigate this question because it is the most similar planet to Earth in the Solar System. Evidence suggests that Mars was once full of water, warmer and had a thicker atmosphere, offering a potentially habitable environment.

Answer:
To start off, let's discuss how these two heroes are similar. First, these heroes we are talking about are teens. Yes, you heard it here folks these people are in between the age of 14 - 18. They also both help others. For example, Brittany Bergquist and her brother Robbie take time out of their day to provide more talk time for soldiers. On the other hand, team made up of girls and boys help people that need medical assistance 24 hours a day. But most importantly they both enjoy, love, and are amazed by what they are doing.

Explanation:
The distinguishable between Food that fuels and minutes that matter is one's to benefit soldiers to help communicate with his family while they fight for our country.
On the other hand is to help keep their families warm during the winter for the parents working to make ends meet.
First similarity of these two are that they both used recycled items to solve their problem within their families and meet the needs in their community.
But don't forget about the smart kids that came up with the idea to recycle their belongings to solve the problem and let nothing go to waste.
Another difference is that the solution to the obstacle affected the families and households different because the circumstances were totally opposite and now a family warm while a solider can call home to his family but all with smiles on their faces.
What is Food?Food is a substance consisting essentially of protein, carbohydrate, fat, and other nutrients used in the body of an organism to sustain growth and vital processes and to furnish energy.
The absorption and utilization of food by the body is fundamental to nutrition and is facilitated by digestion.
Plants, which convert solar energy to food by photosynthesis, are the primary food source.
Animals that feed on plants often serve as sources of food for other animals.
What is Fuel?Fuel is a substance that is burned to provide nuclear energy, heat or power.
Materials like coal, wood, oil, or gas can provide heat when burned. Methanol, Gasoline, Diesel, Propane, Natural gas, Hydrogen are types of fuel. Nuclear energy is produced by burning plutonium.
From fuel efficiency or fuel economy, we can measure how long any vehicle could travel, which is the opposite of fuel consumption.
Fuel consumption is the amount of fuel vehicle uses to travel a particular distance.
Fuel efficiency can be measured in kilometers per liter. The efficiency with which the fuel does a conversion of energy is known as fuel efficiency.

If forests are strictly managed according to the maximum sustainable yield model, some biodiversity would still be lost because ________. species whose habitat depends on mature trees in the top canopy layer will be excluded forests are more susceptible to herbivore damage habitats for nesting birds are lost all the trees are of mature size leaving no room for new seedlings nearly all predators will be excluded
Answer: species whose habitat depends on mature trees in the top canopy layer will be excluded
Explanation:
The maximum sustainable yield refers to a biological resource maximum usable production which can be gotten at a particular period of time without the ability of the resource maintaining that particular production level reduced.
If forests are strictly managed according to this model, some biodiversity would still be lost due to the fact that species whose habitat depends on mature trees in the top canopy layer will be excluded.

Describe the functions and organization of tissue systems in a seed plant.
Answer:
tissues is the protect outer covering of plants
Explanation:
Plants consist of many different types of cells that are organized into aggregates called tissues. Tissues are derived from specialized groups of dividing cells called meristems. Meristems are the source of cells and tissues and therefore they are not strictly speaking tissues themselves
Plants are multicellular eukaryotes with organized tissue and specialized organs with specific tasks.
What are the functions and organization of the tissue system in a seed plant?Plants are multicellular eukaryotes, and their tissue systems are made up of many cell types that serve distinct purposes. Meristematic tissue and permanent (or non-meristematic) tissue are the two main forms of plant tissue systems. Meristems, which are areas of plants that experience continuous cell division and expansion, are where the meristematic tissue's cells may be located. Meristematic tissue cells continue to divide and support plant growth despite being either undifferentiated or incompletely differentiated. Permanent tissue is made up of dormant plant cells, which are no longer actively dividing.Secondary tissues can be simple (made up of similar cell types) or complex (composed of different cell types). Dermal tissue is a simple tissue that covers the plant's exterior and regulates gas exchange. One example of a complex tissue is vascular tissue, which is composed of the specialized conducting tissues xylem and phloem.To learn more about the functions and organization of the tissue system in a seed plant, refer to https://brainly.com/question/17774097

Where are the instructions that control a cell's activities found?
A. DNA
B. mitochondria
C. ribosomes
Answer:
A. DNA
Explanation:
Nucleus. The nucleus, a substantial organelle that houses the cell's DNA, is referred to as the “command center” of the cell (deoxyribonucleic acid). Thus, option A is correct.
What is the main function of DNA?
The genetic information contained in the DNA is used by the nucleus to regulate all cellular functions, including growth and metabolism.
Today, DNA has three separate purposes: genetic, immunological, and structural, all of which differ greatly from one another and depend in different ways on the bases and the sugar phosphate backbone.
Genetic information is encoded in the nucleotide order along the backbone. Replication, information encoding, mutation/recombination, and gene expression are the four functions that DNA performs.
Therefore, DNA which is found in nucleus control a cellular activity.
