Answer:

D. It transports carbohydrates to the roots.

Explanation:

Phloem is mainly used to transport nutrients from their region of production to the region that needs or stores the nutrient.

In photosynthesis, the method that plants make food, starch is produced. As the root hair cells needed energy to function, nutrients is needed so that it can respire and produce energy.

Therefore, when starch is produced, they will travel down the plants by the phloem to the roots where the nutrients is used.

brainlest please

As it delivers carbohydrates to the roots, the phloem in a leaf is vital to a plant's roots. So, the correct option is D.

The plant tissue known as phloem is in charge of moving sugars, nutrients, and other organic substances from the leaves, where they are made by photosynthesis, to the other sections of the plant, such as the roots, flowers, and fruits.

Phloem has a bidirectional transport system that enables it to carry materials both across and down the plant. Sieve-tube elements and companion cells, which make up phloem tissue, are specialised cells.

A vascular tissue called phloem is in charge of moving sugars (carbohydrates) from the leaves to the roots and other sections of the plant. The plant may transfer the byproducts of photosynthesis through its whole system thanks to a process called as translocation.

Therefore, the correct option is D.

ATCG are called the Nitrogenous Base. The DNA(deoxyribonucleic acid) is made up of a phosphate group, 5 Carbon sugar called deoxyribose and Nitrogenous base.

This Nitrogenous bases are further divided into purine and pyrimidine

Purine includes- Adenine and Guanine while pyrimidine includes Thymine and Cytosine or Uracil in the RNA.

When Base pair occurs, Adenine pairs with Thymine while Guanine pairs up with cytosine in DNA.

Answer:

Option-A

Explanation:

In the given question, the artificial ecosystem was prepared by the scientist which included the animals and plants. The light and dark conditions were controlled by a switch and bulb.

In the beginning, the amount of Carbon in the form of carbon dioxide was low due to the utilization of carbon dioxide by plants to perform photosynthesis. Then the amount of carbon dioxide increased in the atmosphere, the reason could be due to less consumption of carbon dioxide. The carbon dioxide is not uptake by plants during night conditions when photosynthesis process slowed down or stops.

Therefore, the dark condition was created by the scientist by switching off the lights and the number of energy molecule decreased as no photosynthesis was occurring.

Thus, Option-A is the correct answer.

Answer:

House sparrows from England were released in the United States. They have competed with native bluebirds. These house sparrows are invasive species.

Explanation:  

House sparrows are invasive species that were introduced in the United States and once established these birds started to compete with native species and managed to displace many native birds. They seriously affected farmlands. Now they are everywhere always associated with human being presence.  

Biologic Invasive species: It refers to new species that disperse and establish in a new area far or out of their original distribution range. Once established, these species expand their distribution from the first invaded spot and overgrows. As they expand, they compete with other species for resources, such as food sources, water, shelter, radiation, exposure, among others. Species are considered to be invasive because of their high reproductive rate, population growth, and interaction with native species, which provokes huge damages in the native ecosystems. It is very common for these species to scape and start new populations in the new area, where they have less environmental pressure and better conditions than in their origin area -fewer predators, more resources, better nitches-, and these factors favor their establishment.

There are some typical steps in an invasion process:

1) Introduction or dispersion to the new area,

2) Naturalization. The new species establishes in the new area. It can grow, reproduce, and make use of resources.

3) Overgrowth and uncontrolled expansion.

4) Interaction with other species.

5) Stabilization.

In some cases biologic invasions are natural processes, that occur in small groups of individuals that can expand to other ecosystems, and the appearing or despairing of barriers promotes their expansion. But these biologic invasions have been accelerated by human beings, referring to this as "human-assisted invasions".

Explanation:

not sure about what does complex means, but if we according on theory of superposition - the top layer of rocks is younger than bottom

it means that the toppest layer is modern

We can observe three strata of fossil-bearing rocks in the diagram. We must take into account the idea of fossil succession in order to determine the conclusion regarding the organisms identified in these layers.

The theory of fossil succession holds that fossils found in rock layers are placed in a specific order. The oldest fossils are found in the bottom layers, while the youngest fossils are found in the top layers, which represents the relative ages of the fossils.

The conclusion that "the organism in Layer C is a modern form of the organism in Layer B" is most likely accurate based on this premise. As a result, the creature in Layer C reflects a more recent or evolved form of the organism in Layer B and existed before the organism in Layer B.

Overall, the concept of fossil succession aids in our comprehension of the relative ages and evolutionary connections of the creatures found in various rock layers.

A parasite

Explanation:

Parasitism is a form of symbiosis where one organism lives on/in another organism, as in the question, and gets a benefit from that organism, while the other organism is harmed. This is denoted by +/-, which means that one is positively impacted and one is negatively impacted, as opposed to commensalism, which is +/0, or mutualism, which is +/+.

An example is tapeworms, which are flatworm parasites that live in the human  intestine; they benefit while the host suffers.

Answer:

Explanation:

Among the causes of protein synthesis disorders, an important place is occupied by various types of alimentary insufficiency (complete or incomplete starvation, lack of essential amino acids in food, violation of a certain quantitative ratio between essential amino acids entering the body).

The protein synthesis correspondingly contributes to the symptoms of the disease by the fact that it produces some dysfunctional or bizarre proteins which significantly stimulate the specific types of disorder in organisms.

Protein synthesis may be defined as a biological process through which cells make protein in order to perform specific functions within the body of living organisms. It occurs in two stages, i.e. transcription and translation.

Transcription is the stage of protein synthesis through which the effective transfer of genetic instructions in DNA to mRNA in the nucleus takes place. While the process of translation involves the process by which a cell makes proteins using the genetic information carried in messenger RNA (mRNA). It occurs in the cytoplasm of the cell.

The disorder of protein synthesis is occupied by numerous kinds of alimentary insufficiency such as entire or incomplete starvation, insufficiency of mandatory amino acids in food, and violation of essential amino acids entering the body.

Answer:

Mars is the red planet; the Moon is an ashy grey; Saturn shines yellow and the Sun is a brilliant, blinding white. But our planet, when seen from the depths of space, whether we rise up above our world only slightly, in low-Earth orbit, or whether we travel to the outer reaches of our Solar System, shines a glorious blue.

Explanation:

Water vapor. The most abundant greenhouse gas, but importantly, it acts as a feedback to the climate. Water vapor increases as the Earth's atmosphere warms, but so does the possibility of clouds and precipitation, making these some of the most important feedback mechanisms to the greenhouse effect.

Carbon dioxide (CO2). A minor but very important component of the atmosphere, carbon dioxide is released through natural processes such as respiration and volcano eruptions and through human activities such as deforestation, land use changes, and burning fossil fuels. Humans have increased atmospheric CO2 concentration by more than a third since the Industrial Revolution began. This is the most important long-lived "forcing" of climate change.

Methane. A hydrocarbon gas produced both through natural sources and human activities, including the decomposition of wastes in landfills, agriculture, and especially rice cultivation, as well as ruminant digestion and manure management associated with domestic livestock. On a molecule-for-molecule basis, methane is a far more active greenhouse gas than carbon dioxide, but also one which is much less abundant in the atmosphere.

Nitrous oxide. A powerful greenhouse gas produced by soil cultivation practices, especially the use of commercial and organic fertilizers, fossil fuel combustion, nitric acid production, and biomass burning.

Chlorofluorocarbons (CFCs). Synthetic compounds entirely of industrial origin used in a number of applications,

You might have heard that the ocean is blue because the sky is blue, and water reflects the skies. Well, the sky is blue; that’s for certain. And the sky is blue because our atmosphere is more efficient at scattering blue (shorter-wavelength) light than red (longer-wavelength) light. This is the reason why the earth looks blue in color.
