The level of the organization includes coral, fish, eels, and the water in a tropical weather system near the Amazon Rainforest is biome. The correct option is A.
What is a biome?While aquatic biomes encompass both oceanic and freshwater biomes, terrestrial biomes are based on land. A place is categorized as a biome based on the species that call it home.
Scientists can identify a biome by defining the temperature range, soil type, and amounts of light and water that are specific to that location and create niches for particular species.
The Conifer Forest is another name for them. The evergreen trees with conical shapes are part of the vegetation. The taiga biome experiences moderate precipitation. Short, rainy summers alternate with long, chilly winters. There is a lot of snowfall in the winter and a lot of rainfall in the summer.

How is fumigant different from pesticides ? Name one natural substance which can be used in place of fumigant
Fumigants are chemicals that are used to kill pests by releasing a gas that penetrates into areas where pests may be hiding. These chemicals are often used to control pests in large, enclosed spaces such as grain storage facilities or ships.
Pesticides, on the other hand, are chemicals that are used to control, repel, or kill pests. Pesticides can be applied in various forms, such as liquids, granules, or sprays, and can be used to control pests on crops, gardens, and other outdoor areas.
One natural substance that can be used in place of a fumigant is thyme. Thyme is a herb that contains a chemical called thymol, which has insecticidal properties. Thymol can be used to control a variety of pests, including mites, insects, and nematodes. It can be applied in various forms, such as a spray or a dust, and is considered to be less toxic and safer to use than synthetic fumigants.
How can people exercise good and wise Dominion over the process of photosynthesis for God's glory
Wise dominion over the process of photosynthesis can be exercised in such a way that all the people and animals can benefit from it and we can use it correctly.
Photosynthesis is a process that plants and other organisms use to convert light energy into chemical energy that can then be released to fuel the organism's activities via cellular respiration. Some of this chemical energy is stored in carbohydrate molecules, such as sugars and starches, which are formed by the reaction of carbon dioxide and water.
Photosynthesis is performed by the majority of plants, algae, and cyanobacteria; these organisms are known as photoautotrophs. Photosynthesis is responsible for producing and maintaining the oxygen content of the Earth's atmosphere, as well as supplying the majority of the energy required for life on Earth.

Why do cancer cells divide and multiple uncontrollably?
Answer:
Most cancer-causing DNA changes occur in sections of DNA called genes. These changes are also called genetic changes. A DNA change can cause genes involved in normal cell growth to become oncogenes. Unlike normal genes, oncogenes cannot be turned off, so they cause uncontrolled cell growth.
Explain how natural selection could lead to a change in allele frequency leading to a change in the color of the frogs.
Answer:
Due to increasing the survival.
Explanation:
The natural selection causes a change in allele frequency leading to a change in the color of the frogs because the colour of the frog helps it in hiding from predators. The population of that frog specie increases which has the ability to hide from the predators in that environment while on the other hand, the population of frog decreases which can easily be seen by the predator due to its colour so this change in allele frequency will leads to natural selection.
What is Mendel's law of segregation What do we called his factors today and where are they located?
The two alleles for a particular gene separate throughout the development of gametes, according to Mendel's law of segregation, leaving just one allele for each gamete. This indicates that just one allele from each parent is passed on to the offspring for a particular gene when the gametes combine at fertilization.
Mendel's factors have come to be known as genes. A gene is a section of DNA that contains the instructions for making a particular protein, which in turn defines a certain trait.
Chromosomes, which are situated in the nucleus of cells, are where genes are found. Each gene in diploid organisms like pea plants has two alleles, one of which is inherited from each parent.
Mendel's law of segregation explains Mendel's observed inheritance of single traits in his pea plants and it is the basis for Mendel's Punnett square, a tool that is widely used today to predict the possible outcomes of genetic crosses.

What products are made in light-dependent reactions (photosynthesis)?
What products are made in light-independent reactions (photosynthesis)?
Products: ADP, ATP, NADPH, NADP+, Oxygen, Sugars
The products of the light-dependent reactions are= ATP, NADPH, and O2, and the products of light-independent reactions are= Sugars, ADP, and NADP+.
Photosynthesis has two parts: one is light-dependent and another one is a light-independent reaction (also known as-Calvin cycle). The process is vice versa, where few inputs of the light-dependent reaction are used to make the outputs for the light-independent reaction, and few inputs of the light-independent reaction are used to make the outputs for the light-dependent reaction.
The goal of a light-dependent reaction is to convert light energy into chemical energy. And the location of light-independent reaction is at Chloroplasts—stroma.

Is the claim, "Despite not being a plant, you get your energy from the sun." accurate?
Write a paragraph explaining your reasoning.
Answer:
Yes (kind of), because even though we do not use the sun as directly as say plants, we still rely on the sun on a daily basis, however we don't necessarily get our energy from it, like plants do.
The sun produces light as well as heat, also known as solar energy. This makes it possible for life to exist on Earth, and we can use solar energy to power a wide variety of useful things, however sun/solar energy is not the only way to get electricity.
As we know, plants need sunlight to grow, although humans don't grow by being exposed to sunlight, sunlight helps grow plants which animals, including humans, need for food as well as oxygen they produce.
Most livestock we eat, cows for example, need plants to survive and many people eat meat, and even if you don't you'd eat plants which, once again, need sunlight to grow. Also, without heat from the sun, Earth would freeze.

Why does an increase in number of cells cause growth?
Growth in all organisms occurs through the process of mitotic cell division. Cell division is the process of dividing old cells to form new cells, thereby increasing the number of cells needed for growth and various other activities in the body. It is a major and regular process essential to all life.
During mitosis, cells divide to form two identical daughter cells. All cells undergo mitosis and in this way the number of cells in the body increases and the organism grows.
Body tissue grows by increasing the number of cells that make it up. Cells in many tissues of the body divide and grow very rapidly into adulthood. As we grow, many cells mature and specialize in specific tasks in the body.

An organism can pass a gene mutation to its offspring if the mutation occurs in gamete as a result of sexual reproduction .
A mutation can be transmitted down to an organism's progeny if it happens in a germ-line cell (a cell that will develop into gametes, such as egg or sperm). This implies that the mutation will be present in each and every cell of the growing embryo. A parent's genetic mutation may be carried on to their child through their egg or sperm.
Throughout a human's life, these inherited mutations are prevalent in almost every cell of their body. Cystic fibrosis, haemophilia, and sickle cell disease are examples of hereditary mutations. Large-scale evolution only takes into account mutations that can be passed on to future generations. These are known as germ line mutations and they happen in reproductive cells such as eggs and sperm. Environmental factors contribute to mutations.
