3.Stems have trichomes
Roots
1 show positive gravitrotropism
2 absorb water and Minerals
3 bears root hairs
Roots are the underground part of the plant, and the main function is the absorption of water and minerals from the soil, conduction, storage of reserve foods and mainly in the anchorage of the plant. The chief distinction from the stems is the lacking of buds and leaf scars, but have root cap and branches that originate from internal tissues than from buds. And Stems are the part of the plant, that possesses buds, leaves and roots at its basal ends. The primary function of the stem supports the leaves and to transport minerals and water to the leaves, where it proceeded to convert into useful products by the process of photosynthesis, and then further these are transported to other parts of the plants including roots.

How do plants grow without soil
Answer:
Using a growing method called "hydroponics," you can grow plants in a watery solution of mineral nutrients instead of soil. The word “hydroponic" comes from the Greek words hydro (“water") and ponos (“labor"). The keys to plant growth are a variety of mineral nutrients, including nitrogen, phosphorus, and potassium.
Explanation:
Final answer:
Plants can grow without soil by receiving essential elements and nutrients through methods like hydroponics and aeroponics, where these are provided in a water solution. The process of photosynthesis, which requires sunlight, also plays a vital role in plant growth by creating the energy plants need.
Explanation:
Plants can grow without soil through methods such as hydroponics and aeroponics, which use nutrient solutions to feed the plants. In these systems, essential elements required for plant growth, such as nitrogen, phosphorus, potassium, and various micronutrients, are dissolved in water, creating a soil-less growing environment. While soil can provide these nutrients, plants primarily absorb inorganic nutrients and water through their roots and carbon dioxide from the air for photosynthesis, the process by which they gain energy and grow. In addition to nutrients and carbon dioxide, sunlight is crucial as it powers photosynthesis. Plants also exhibit adaptations for growth such as the apical meristem which is an area of active cell division allowing for lengthening of the stems and roots. Hence, as long as plants have access to their essential elements, water, and sunlight, they can thrive even without soil.
4. What does a total solar eclipse look like from Earth?
5. What is the difference between a new moon and a lunar eclipse?
4. When you look up to the sky, it appears as a dark circle with halo light at its edges moving across the face of the sun. As it does, depending on the relative position of the person on earth – that determines where they are on the umbra or penumbra of the eclipse, the place becomes a daytime twilight (umbra) or partial twilight (penumbra).
5. A new moon is formed when the moon is in between the sun and the earth. This is converse to the case of a lunar eclipse where the earth is between the sun and moon. In a new moon, the face of the moon that is faced towards the earth is dark because it is not lit by the sun. It is important to note that a solar eclipse is not formed because the moon’s orbit, around the earth, is tilted at an angle.

Tobin learns that using aluminum cans and plastic bottles can damage the environment. He begins writing the proposal below to suggest a way to reduce their impact.
People should be worried about the environmental effects of using cans and bottles. People use about 200 billion aluminum cans and 500 billion plastic bottles each year. To meet this demand, many new aluminum cans and plastic bottles are made each year. Making new aluminum cans requires minerals and making new plastic bottles requires fossil fuels. Getting these materials from the Earth can damage the environment and cause pollution.
Recycling cans and bottles decreases the amount of new materials that are needed to make more of them. About 68% of aluminum cans are recycled, but only about 7% of plastic bottles are recycled. Many of these plastic bottles end up in landfills or in the ocean.
Which argument would best complete Tobin's proposal?
A.
Encouraging people to use more aluminum is one of the best ways to protect the ocean.
B.
Encouraging people to recycle plastic bottles is the best way to protect the environment.
C.
People should make sure to dispose of their plastic bottles in landfills and not in the ocean.
D.
People can reduce their effect on the environment by recycling more of their aluminum and plastic.

A. rose water
B. red tide
C. crimson summer
D. scarlet wave
Answer: B. Red tide
Explanation:
Answer: B. red tide
Explanation:
Red tide is a phenomena that is caused by algal bloom specifically due to the growth and abundance of unicellular algae called as dinoflagellates and diatoms. These organisms impart red color to the coastal waters. Such kind of algal blooms release toxins in the water. They deplete the concentration of oxygen in the water body.
The shellfish consume these small unicellular organisms as they filter large amount of water. The shellfish population accumulates large amount of toxins on consumption of these small organisms. The shellfish are harvested and consumed by the human population can make them sick and may lead to mortality of large population.

Mung beans planted early in the spring produce flowers at the same time as mung bean plants planted early in the summer due to the A) age of the plant. B) length of darkness. C) amount of moisture. D) amount of fertilizer.
C) amount of moisture
Answer: Option B
Explanation:
The mung beans is planted early in the spring season and produce flowers at the same time if it is planted in the early summer.
This is so because the time for which the seeds need sunlight is limited. The beans will get energy and light in the same amount even if it is planted at the starting of the summer season,.
This is due to the darkness that the beans receive when it is not being exposed to the sunlight and outer environment.
Hence, the correct answer is option B
Many cows are given antibiotics as part of their regular diet. It has been determined that these antibiotics can be detected in the milk of these cow. How do you think this might effect the yogurt making process?
Answer:
When providing antibiotics to cows, it provides unspecified chemicals that can range to many different issues. These chemicals can both affect the cow and its produce. Asserting the fact into yogurt, this antibiotic(dependant on its chemical) can affect the product within both positive and negative ways. If the chemical is positive, it can increase mass,taste and even quality. If it is negative, it can create a bad taste,bad quality and even transmit diseases!
Antibiotics in a cow's diet can lead to antibiotic-resistant bacteria. These resistant bacteria could affect the probiotic bacteria used in the yogurt-making process potentially hindering the fermentation and production of yogurt.
Explanation:Antibiotics given to cows can be detected in their milk which might affect the yogurt production process. These antibiotics could potentially select for antibiotic resistance in bacteria, including those involved in yogurt fermentation. The routine use of antibiotics in livestock feed can cultivate bacteria resistant to antibiotics. This could thereby affect the bacteria that is necessary for the yogurt-making process.
Furthermore, these resistant bacteria may produce mobile genetic elements, transferring resistance genes amongst each other, and these could also impact the probiotic bacteria used in yogurt production. Probiotics are beneficial bacteria integral to human gut health and to the creation of yogurt. The likely outcome would be a disruption in the fermentation process, possibly hindering the production of yogurt.

organisms use nitrogen in which one of the following ways?
Final answer:
Organisms use nitrogen in different ways, such as through nitrogen fixation by bacteria for plants and by consuming nitrogen-containing compounds for heterotrophs. Legumes have a symbiotic relationship with nitrogen-fixing bacteria, which contributes to their nitrogen acquisition.
Explanation:
Living organisms use nitrogen in several ways:
Plants: Plants acquire nitrogen as nitrate or ammonia dissolved in water. Nitrogen fixation is the primary source of nitrogen used by plants in most ecosystems.
Heterotrophs: Nitrogen is obtained from the food they eat, primarily from proteins, nucleic acids, and nucleotides.
Legumes: Legumes have a symbiotic relationship with certain nitrogen-fixing bacteria known as rhizobia. These bacteria fix free nitrogen, release it in the form of ammonia, which combines with carbon compounds in the plant cells to produce amino acids.
Mendel is considered the Father of Genetics. His famous pea plant experiments helped to formulate several laws in genetics that have stood the test of time with very little modification. Match each law or term with the correct description/definition.
Johann Gregor Mendel, known as the father of genetics, developed two key laws regarding heredity while studying pea plants: the Law of Segregation and the Law of Independent Assortment. These laws explain how traits are passed from parents to offspring and laid the foundation for Mendelian genetics.
Explanation:Johann Gregor Mendel, an Austrian monk, is widely acknowledged as the father of genetics. His experiments on pea plants in the mid-19th century provide an understanding of heredity, which is the transmission of genetic characteristics from parent to offspring. Fundamentally, Mendel developed two laws from his experiments: the Law of Segregation and the Law of Independent Assortment.
The Law of Segregation states that each inherited trait is defined by a pair of genes. Parents pass on a random copy of these genes to their offspring. Hence, offspring have two copies of each gene — one from each parent.
The Law of Independent Assortment postulates that different traits are passed independently of one another from parents to offspring. This law explains the diverse combinations of traits in offspring.
In his work, Mendel demonstrated that traits are transmitted from parents to offspring independently of other traits following dominant and recessive patterns. This discovery laid the foundation of classical or Mendelian genetics.

Which is a disease that begins as a rash with small red bumps that develops into blisters? A. tuberculosis B. mononucleosis C. hepatitis B D. chicken pox
Chickenpox is a disease that begins as a rash of small red bumps that develops into blisters. So the correct option is D.
What is chicken pox?Varicella-zoster, another name for chickenpox, causes a red rash that blisters and then crusts over. It spreads rapidly. Vaccines can help you avoid getting chickenpox and its subsequent complication, shingles.
A skin rash is brought on by the illness known as chickenpox. The varicella-zoster virus is the pathogen responsible for the illness. (The actual chickenpox is also known as varicella-zoster.) If they haven't had a chickenpox vaccination, the majority of people will contract the virus while they are young.
A youngster who has chickenpox can readily infect other kids with the illness. Due to widespread childhood vaccination, chickenpox is considerably less frequent nowadays. Before the first chickenpox vaccine was authorized in the United States in 1995, practically everyone contracted the disease. There weren't many issues.
You cannot contract chickenpox from another individual after having it once. You can contract chickenpox at any age if you haven't had the vaccination. It is safer to contract chickenpox as a child or avoid it by getting vaccinated because adults who contract it may become really ill.
Therefore the correct option is D.

Roles of gases between photosynthesis and cellular respiration?
Answer:
Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O Photosynthesis: 6CO2 + 6H2O → C6H12O6+ 6O2Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water. While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration. We breathe in that oxygen, which is carried through our blood to all our cells. In our cells, oxygen allows cellular respiration to proceed. Cellular respiration works best in the presence of oxygen. Without oxygen, much less ATP would be produced.
Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere. The exchange of carbon dioxide and oxygen during photosynthesis and cellular respiration worldwide helps to keep atmospheric oxygen and carbon dioxide at stable levels.

A) Progesterone controls the release of eggs.
B) Progesterone Kills sperm Cells.
C) Sperm are made of Progesterone
D) Women normally have no Progesterone in their bodies.
Birth control pills contain progesterone because Progesterone controls the release of eggs.
How does progesterone prevent birth.Progesterone and estrogen are hormones that are synthesized in birth control pills. They keep hormone levels steady, which prevents ovulation. The ovary doesn't get the signal to release an egg if estrogen levels aren't high enough. Keep in mind that if you don't have an egg, you won't be able to conceive.Ovulation is prevented when estrogen and progestin are combined (the release of eggs from the ovaries). They also alter the uterine lining (womb) to prevent pregnancy, as well as the mucus at the cervix (uterine opening) to keep sperm (male reproductive cells) out.learn more about progesterone here:
