Plants take energy
from the sun
and make food, which for plants is

Answers

Answer:

Photosynthesis

Explanation:

Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.

Answer:

[tex]\boxed {\boxed {\sf Glucose}}[/tex]

Explanation:

Plants (plus some bacteria and algae) are autotrophs and undergo a process called photosynthesis.

They obtain light energy from the sun and capture it using a green pigment called chlorophyll, water from the soil is drawn up through the roots with capillary action, and carbon dioxide diffuses into stoma on leaves.

Then, in the chloroplast, these substances are turned into oxygen and glucose. Both of these are used in cellular respiration, which creates energy for the plant to grow and carry out cellular and biological functions. Therefore, glucose is often called "food" for the plant.

What type of compound is water according to its chemical bonds?​

Answers

Explanation:

Water as a Compound and Molecule

A compound forms whenever two or more atoms form chemical bonds with each other. The chemical formula for water is H2O, which means each molecule of water consists of one oxygen atom chemically bonded to two hydrogen atoms. Thus, water is a compound. It's also a molecule, which is any chemical species formed by two or more atoms chemically bonded to each other. The terms "molecule" and "compound" mean the same thing and can be used interchangeably.

Sometimes confusion arises because the definitions of molecule and compound haven't always been so clear-cut. In the past, some schools taught that molecules consisted of atoms bonded via covalent chemical bonds, while compounds were formed via ionic bonds. The hydrogen and oxygen atoms in water are covalently bonded, so under these older definitions, water would be a molecule but not a compound. An example of a compound would be table salt, NaCl. However, as scientists came to understand chemical bonding better, the line between ionic and covalent bonds became fuzzier.

Answer: water is a polar molecule

Explanation: water H2O has two covalent bonds between Oxygen and Hydrogen atoms. Both are non-metals and share outer electrons for forming a covalent bond.

Oxygen has much greater electronegativity and it pulls shared electrons with greater force. So bond is polar and because molecule is V-shaped, Oxygen has permanent

Negative partial charge. Also molecule is polar and makes Hydrogen bonds with other water molecules.

What is the food chain?

A food chain describes which creature in the ecosystem consumes another. The food chain is a succession of living things that transmit nutrients and energy from one creature to the next. When one organism ingests another, this happens. Following the chain, starts with the producer organism and finishes with the decomposer organism.

The sequence of events in an ecosystem known as a "food chain" occurs when one live organism consumes another organism, which is then eaten by a bigger organism. A food chain is created by the transfer of nutrients and energy from one creature to another at various trophic levels.

The feeding habits or connections between living things are also explained by the food chain. Trophic level is the term used to describe the orderly phases in a food chain, from producers at the bottom through primary, secondary, and tertiary consumers. A trophic level is any position along a food chain.

Therefore, the owl population would decrease if their prey's population decreased.

One hot summer day Thomas left a glass of full of water outside when he went back to get it the next day half of the water was gone what type of interaction with the Earth system was this
A.Lithosphere-Biosphere
B.Hydrosphere-Atmosphere

Answers

Answer:

B

Explanation:

Hydrosphere-Atmosphere

B. Hydrosphere-Atmosphere

The hydrosphere comprises the totality of Earth's water. The atmosphere comprises the totality of Earth's air. The liquid water in the glass that was left outside evaporated, turning into gaseous water vapor that escaped the glass. The water as a liquid in the glass and as a vapor as a gas are both part of the hydrosphere. But once some of the liquid water became gaseous water vapor, that water became part of the Earth's atmosphere.

For a circular or square patch of habitat, the ratio of edge habitat to interior habitat __________ as the size of the patch decreases. View Available Hint(s) For a circular or square patch of habitat, the ratio of edge habitat to interior habitat __________ as the size of the patch decreases. decreases increases in square patches and decreases in circular patches increases remains unchanged increases in circular patches and decreases in square patches

Answers

Answer:

increases

Explanation:

Habitat is defined as a particular environment where a group of organisms normally lives. Some examples of habitat include, among others, forests, deserts, lakes, grasslands, etc. Moreover, an edge habitat refers to a habitat area that is in contact with another. This part of the habitat has ecological importance because it is used by many species in order to find food, refuge and rest. In the question above, it is expected that a greater number of smaller habitats increase edge habitat surface area when compared to the interior habitat area. The ratio between the edge habitat surface area and total habitat area may have a huge impact on entire ecosystems.

Translation: Methionine-Glycine-Leucine-Serine-Aspartic acid (abbreviation: MGLSD)

Explanation:

The genetic code refers to the universal rules by which cells decodes information encoded within genetic material, either DNA or the resulting messenger RNA (mRNA), into proteins. In the genetic code, each triplet of nucleotide bases or 'codon' in the DNA/RNA sequence determines a specific amino acid in the protein. The AUG codon in mRNA is a start codon that specifies Methionine (M) amino acid, while UAG, UAA, and UGA are stop codons that determine the end of the protein.
