Which best describes arteries and veins?

Answers

Answer 1
Answer:

Arteries carry oxygenated blood away from the heart, while veins carry deoxygenated blood towards the heart. Option A

What is the arteries?

The circulatory system has two different types of blood vessels: arteries and veins. They perform separate tasks and move blood in various ways.

Blood that has been oxygenated leaves the heart and is sent to other regions of the body by way of arteries. Because of their strong and elastic walls, they can endure the intense pressure that the heart's pumping motion creates. Arterioles, which are arteries that branch off into smaller vessels, carry blood to capillaries in tissues.

The basic food produced by a plant is:a- produced by chloroplasts
b- produced by mitochondria
c- absorbed through the roots

Answers

Mitochondria is a powerhouse inside a cell, and Chloroplasts are a specialized organelle found in plant cells and contain chlorophyll. These are responsible for plants green colour and their ability to absorb energy from the sun.

produced by chloroplast

Which organelle, found in this plant cell, breaks down sugars for cellular energy?

Answers

Answer: Mitochondria

Explanation:

The mitochondria is the organelle that is responsible for the process of cellular respiration. During this process the sugar that is produced is broken down into a usable form of energy.

The energy from the bonds of carbohydrates is stored in the form of ATP which is a high energy particle used for the various processes in the plant body.

The mitochondria is also known as the power house of the cell because it is the main site of ATP production.
Mitochondria is the power house of the cell. It breaks down sugar (among another things) to produce energy.

One thing that ALL biogeochemical cycles have in common isthey involve the movement of specific chemicals between living and non-living things.


they involve the changing of carbon into carbon dioxide.


they are pathways for elements that get passed between only non-living things.

Answers


they involve the movement of specific chemicals between living and non-living things.

The biogeochemical cycles move through mainly the biotic and abiotic components of the earth, more elaborately the spheres -biospheres, lithosphere, hydrosphere and atmosphere regions of the ecosystem. These biogeochemical cycles, from its terminology and discernable word morphology- involves the biological, geological and chemical components that make out to complete an exact and purposed cycle. 

Final answer:

All biogeochemical cycles share the common trait of facilitating the movement of specific chemicals between living and non-living entities in an ecosystem. They cycle essential substances like water, carbon, nitrogen, and others through the environment.

Explanation:

All biogeochemical cycles indeed have one crucial aspect in common: they involve the movement of specific chemicals between living (biotic) and non-living (abiotic) components of an ecosystem.

The cycles include important substances like water, carbon, nitrogen, phosphorus, and sulfur which are cycled through the environment.

To specify, these are not cycles that only involve the conversion of carbon into carbon dioxide or paths that get passed between only the non-living things. Instead, in these cycles, elements are passed back and forth between living and non-living matter in a continuous loop, which provides essential nutrients to support life on Earth.

Some protists form long, foot-like projections of their cell membrane and cytoplasm that are used for movement and to capture food. What is the name of these structures?cilia
flagella
mycelia
pseudopods

Answers

Answer;

-Pseudopods

Explanation;

-Pseudopods are temporary cytoplasmic projections of the cell membrane in certain unicellular protists such as amoeba.They are used in some eukaryotic cells to move around or to eat. Most cells that do this are called amoeboids. The amoeba is a common example.

-The functions of pseudopodia include locomotion and the capturing of prey. Pseudopodia are critical in sensing prey that can then be engulfed; the engulfing pseudopodia are called phagocytosis pseudopodia.
