Answer:

La cromatina es una sustancia dentro de un cromosoma que consiste en ADN y proteínas. El ADN lleva las instrucciones genéticas de la célula. Las principales proteínas de la cromatina son las histonas, que ayudan a empaquetar el ADN de una forma compacta que cabe en el núcleo celular. Los cambios en la estructura de la cromatina se asocian con la replicación del ADN y la expresión génica.

Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

Answer:

The process by which plants turn carbondioxide and water into carbohydrates and oxygen using  light energy trapped by chlorophyll, is called photosynthesis.

It destroys animal habitats and causes topsoil to erode- deforestation 2) pollutes groundwater with dangerous chemicals- injecting fracking fluids into the ground 3) harms aquatic creatures and vegetation- oil spills during transport on a ship.

In order to enhance the amount of hydrocarbons that may be extracted, drilling operations use fracking fluid (also known as frac fluid). The fluid stops the well from corroding. Among other things, it prevents blockages, bacteria from growing, and lubricates the extraction process.

In summary, the chemical composition varies from well to well and is complicated. Depending on the exposure amount, several of these substances can be dangerous to human health.

According to estimates from the oil and gas sector, chemical additives only make up about 1%.

Therefore, It destroys animal habitats and causes topsoil to erode- deforestation 2) pollutes groundwater with dangerous chemicals- injecting fracking fluids into the ground 3) harms aquatic creatures and vegetation- oil spills during transport on a ship.

Answer:

There isn't wind all the time, so wind being used as a major energy source is very unlikely.

Answer:

there isnt always a lot of wind so it wouldnt be a reliable energy source

Explanation:

Answer:

Positive Human Interaction When people build dams channeling off large bodies of water, the water builds up along the edge of the lake, pond, or stream creating very fertile soil from the constant watering and these areas on the outside of lakes and ponds are used by humans for growing and farming crops.

Explanation:

Answer:

This process of making sugar and oxygen is called photosynthesis. Pond weed uses the carbon dioxide which is dissolved in the water it is in. The amount of dissolved carbon dioxide can be varied by adding sodium hydrogen carbonate (carbon dioxide solution) to the water.

Answer:

Cellulose - It is described as a complex carbohydrate that forms the main constituent of the cell wall in most plants and is important in the manufacture of numerous products like pharmaceuticals, textiles, etc.

Chlorophyll - Any of a group of green pigments that are found in the chloroplasts of plants and in other photosynthetic organisms such as cyanobacteria.

Chloroplast - An organelle found in the cells of green plants and in photosynthetic algae, where photosynthesis takes place.  

Bryophyte - Any plant of the division Bryophyta, defined "sensu lato" to comprise the mosses, liverworts, and hornworts, and corresponding to all embryophytes that are not vascular plants.

Pterophyte - It is characterized as any fern(seedless plant) that is a division of Pteridophyta.

Gymnosperm - Any plant such as a conifer whose seeds are not enclosed in an ovary or those who don't bear seeds or fruits. Example; Cycads.

Cone - A cone-shaped flower head of various plants like banksias and proteas.

Angiosperm - Any flowering plant characterized by having ovules enclosed in an ovary and thus, produces fruits, as well as, seeds.

Flower - A reproductive structure in angiosperms and often conspicuously colorful and typically including sepals, petals, and either or both stamens and/or a pistil.

Cuticle - A noncellular protective covering outside the many invertebrates and plants.

Vascular tissue - The complex tissues that consist of various cell types and primarily responsible for transporting liquid and other nutrients throughout the plant or animal body.

Xylem - A vascular tissue in the land plants primarily responsible for the distribution of water and minerals that are taken up by the roots and also the key component of the wood.

Phloem - A vascular tissue in land plants primarily responsible for the distribution of sugars and the nutrients manufactured in the shoot.

Roots - The part of the plant which is generally underground that anchors and supports the plant body. It absorbs and stores water and nutrients, and in some plants is able to perform vegetative propagation.

Root hairs - The rhizoid of a vascular plant or a tabular outgrowth of a trichoblast, hair-forming cell on the epidermis of a plant root.

Stems - The above-ground stalk of a vascular plant that supports individual parts of a plant like leaves, flower, fruits, etc.

Leaves - The green and flat organ that represents the most prominent feature of the most vegetative plants.

Photosynthesis - The process by which plants and other photoautotrophs convert light energy into chemical energy. For example; Plants use air, water, along with sunlight to synthesize their food(carbohydrates and waste oxygen).

Answer:

Presence of predators.

Explanation:

Presence and absence of predators is the main cause of the presence of spines on stickleback fish populations because these spines helps in the protection against predators. The stickleback fish populations that lives in marine ecosystem have spines because there are many predators are present while on the other hand, stickleback fish populations of freshwater ecosystems have no spines due to no predator so they acquire the adaptation of having no spines.

In this exercise we have to explain the variations of the aquatic system, so we have to:

In this case, as long as a large increase in a specific population of fish takes place, we know that the predators of this system are needed.

They are:

Answer:

c. it ensures that the replicated DNA is an exact copy of the parent DNA

Explanation:

This means that each of the two strands in double-stranded DNA acts as a template to produce two new strands. Replication relies on complementary base pairing, that is the principle explained by Chargaff's rules: adenine (A) always bonds with thymine (T) and cytosine (C) always bonds with guanine (G).

Answer:a

a possible explanation for this occurrence is that a test tube or dropper was accidentally used repeatedly without being sterilized, causing sample cross-contamination. DNA in this test case did not confirm that the father of the second child was another client of the fertility clinic who had never met the mother...therefore this is a possibility.

Hello. You have not submitted the experiments to which this question refers, which makes it impossible for it to be answered. However, I will try to help you in the best possible way.

A dependent variable is one that is influenced by an element, in order to present a result, that is, it is a variable that does not establish itself, being dependent on another variable to establish itself. An example of a dependent variable can be seen in an experiment that seeks to determine the differences in growth rates of bean plants that were fertilized with different organic fertilizers. As you can see, this is an experiment where the different organic fertilizers influence differences in the growth rate of bean plants. Thus, the growth of these plants depends on the fertilizer, this growth being the variable dependent on the experiment.

A control group, in turn, is an element of the experiment that does not receive the element that is being tested in the same experiment. The control group is important, because it allows the researcher to see the results of a system where the tested element does not exist, thus being able to determine the real differences that the tested element is capable of causing. Using the same example presented in the paragraph above, we can see that the different organic fertilizers are the elements tested in the experiment. These fertilizers will be applied to the plants, however it is important that at least one of these plants does not receive any fertilizer, so that the difference between a system with fertilizer and a system without fertilizer can be evaluated. This plant that received no fertilizer is the control group.

D. I'm pretty sure at least
